A scan of the skull of a 319-million-year-old fossilized fish has led to the discovery of the oldest example of a well-preserved vertebrate brain, shining a new light on the early evolution of bony fish.

The fossil of the skull belonging to the extinct Coccocephalus wildi was found in a coal mine in England more than a century ago, according to researchers of the study published in the journal Nature on Wednesday.

The fossil is the only known specimen of the fish species so scientists from the University of Michigan in the US and the University of Birmingham in the UK used the nondestructive imaging technique of computed tomography (CT) scanning to look inside its skull and examine its internal bodily structure.

Upon doing so, came a surprise. The CT image showed an “unidentified blob,” a University of Michigan press release said.

The distinct, 3D object had a clearly defined structure with features found in vertebrate brains: It was bilaterally symmetrical, contained hollow spaces similar in appearance to ventricles and had extending filaments that resembled cranial nerves.

“This is such an exciting and unanticipated find,” study coauthor Sam Giles, a vertebrate paleontologist and senior research fellow at the University of Birmingham, told CNN Thursday, adding that they had “no idea” there was a brain inside when they decided to study the skull.

“It was so unexpected that it took us a while to be certain that it actually was a brain. Aside from being just a preservational curiosity, the anatomy of the brain in this fossil has big implications for our understanding of brain evolution in fishes,” she added.

C. wildi was an early ray-finned fish – possessing a backbone and fins supported by bony rods called “rays” – that is thought to have been 6 to 8 inches long, swum in an estuary, and ate small aquatic animals and aquatic insects, according to the researchers.

The brains of living ray-finned fish display structural features not seen in other vertebrates, most notably a forebrain consisting of neural tissue that folds outward, according to the study. In other vertebrates, this neural tissue folds inward.

C. wildi lacks this hallmark feature of ray-finned fish, with the configuration of a part of its forebrain called the “telencephalon” more closely resembling that of other vertebrates, such as amphibians, birds, reptiles and mammals, according to the study authors.

“This indicates that the telencephalon configuration seen in living ray-finned fishes must have emerged much later than previously thought,” lead study author Rodrigo Tinoco Figueroa, a doctoral student at the University of Michigan’s Museum of Paleontology, said.

He added that “our knowledge on the evolution of the vertebrate brain is mostly restricted to what we know from living species,” but “this fossil helps us fill important gaps in the knowledge, that could only be obtained from exceptional fossils like this.”

Unlike hard bones and teeth, scientists rarely find brain tissue – which is soft – preserved in vertebrate fossils, according to the researchers.

However, the study noted that C. wildi’s brain was “exceptionally” well preserved. While there are invertebrate brains up to 500 million years old that have been found, they are all flattened, said Giles, who added that this vertebrate brain is “the oldest three-dimensional fossil brain of anything we know.”

The skull was found in layers of soapstone. Low oxygen concentration, rapid burial by fine-grained sediment, and a very compact and protective braincase played key roles in preserving the brain of the fish, according to Figueroa.

The braincase created a chemical micro-environment around the enclosed brain that could have helped to replace its soft tissue with dense mineral that maintained the fine details of the brain’s 3D structures.

Giles said: “The next steps are to figure out exactly how such delicate features as the brain can be preserved for hundreds of millions of years, and look for more fossils that also preserve the brain.”

Neanderthals hunted and butchered giant elephants

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.



CNN
 — 

Some 125,000 years ago, enormous elephants that weighed as much as eight cars each roamed in what’s now northern Europe.

Scientifically known as Palaeoloxodon antiquus, the towering animals were the largest land mammals of the Pleistocene, standing more than 13 feet (4 meters) high. Despite this imposing size, the now-extinct straight-tusked elephants were routinely hunted and systematically butchered for their meat by Neanderthals, according to a new study of the remains of 70 of the animals found at a site in central Germany known as Neumark-Nord, near the city of Halle.

The discovery is shaking up what we know about how the extinct hominins, who existed for more than 300,000 years before disappearing about 40,000 years ago, organized their lives. Neanderthals were extremely skilled hunters, knew how to preserve meat and lived a more settled existence in groups that were larger than many scholars had envisaged, the research has suggested.

A distinct pattern of repetitive cut marks on the surface of the well-preserved bones — the same position on different animals and on the left and right skeletal parts of an individual animal — revealed that the giant elephants were dismembered for their meat, fat and brains after death, following a more or less standard procedure over a period of about 2,000 years. Given a single adult male animal weighed 13 metric tons (twice as much as an African elephant), the butchering process likely involved a large number of people and took days to complete.

Stone tools have been found in northern Europe with other straight-tusked elephant remains that had some cut marks. However, scientists have never had clarity on whether early humans actively hunted elephants or scavenged meat from those that died of natural causes. The sheer number of elephant bones with the systematic pattern of cut marks put this debate to rest, said the authors of the study published Wednesday in the journal Science Advances.

The Neanderthals likely used thrusting and throwing spears, which have been found at another site in Germany, to target male elephants because of their larger size and solitary behavior, said study coauthor Wil Roebroeks, a professor of Paleolithic archaeology at Leiden University in Germany. The demographics of the site skewed toward older and male elephants than would be expected had the animals died naturally, according to the study.

“It’s a matter of immobilizing these animals or driving them into muddy shores so that their weight works against them,” he said. “If you can immobilize one with a few people and corner them into an area where they get stuck. It’s a matter of finishing them off.”

What was most startling about the discovery was not that Neanderthals were capable of hunting such large animals but that they knew what to do with the meat, said Britt M. Starkovich, a researcher at the Senckenberg Centre for Human Evolution and Palaeoenvironment at the University of Tübingen in Germany, in commentary published alongside the study.

“The yield is mindboggling: more than 2,500 daily portions of 4,000 calories per portion. A group of 25 foragers could thus eat a straight-tusked elephant for 3 months, 100 foragers could eat for a month, and 350 people could eat for a week,” wrote Starkovich, who was not involved in the research.

“Neanderthals knew what they were doing. They knew which kinds of individuals to hunt, where to find them, and how to execute the attack. Critically, they knew what to expect with a massive butchery effort and an even larger meat return.”

The Neanderthals living there likely knew how to preserve and store meat, perhaps through the use of fire and smoke, Roebroeks said. It’s also possible that such a meat bonanza was an opportunity for temporary gatherings of people from a larger social network, said study coauthor Sabine Gaudzinski-Windheuser, a professor of prehistoric and protohistoric archaeology at the Johannes Gutenberg-University in Mainz, Germany.

She explained the occasion could perhaps have served as a marriage market. An October 2022 study based on ancient DNA from a small group of Neanderthals living in what’s now Siberia suggested that women married outside their own community, noted Gaudzinski-Windheuser, who is also director of the Monrepos Archaeological Research Centre and Museum of Human Behavioural Evolution in Neuwied.

“We don’t see that in the archaeological record but I think the real benefit of this study is that now everything’s on the table,” she said.

Scientists had long thought that Neanderthals were highly mobile and lived in small groups of 20 or less. However, this latest finding suggested that they may have lived in much bigger groups and been more sedentary at this particular place and time, when food was plentiful and the climate benign. The climate at the time — before the ice sheets advanced at the start of the last ice age around 100,000 to 25,000 years ago — would have been similar to today’s conditions.

Killing a tusked elephant would not have been an everyday event, the study found, with approximately one animal killed every five to six years at this location based on the number found. It’s possible, however, that more elephant remains were destroyed as the site is part of a open cast mine, according to the researchers. Other finds at the site suggested Neanderthals hunted a wide array of animals across a lake landscape populated by wild horses, fallow deer and red deer.

More broadly, the study underscores the fact that Neanderthals weren’t brutish cave dwellers so often depicted in popular culture. In fact, the opposite is true: They were skilled hunters, understood how to process and preserve food, and thrived in a variety of different ecosystems and climates. Neanderthals also made sophisticated tools, yarn and art, and they buried their dead with care.

“To the more recognizably human traits that we know Neanderthals had — taking care of the sick, burying their dead, and occasional symbolic representation — we now also need to consider that they had preservation technologies to store food and were occasionally semi sedentary or that they sometimes operated in groups larger than we ever imagined,” Starkovich said.

How do you lose a radioactive capsule? Australian investigators are wondering too


Brisbane, Australia
CNN
 — 

The discovery of a tiny lost radioactive capsule beside a remote highway in Western Australia raises many questions – not least how it escaped layers of radiation-proof packaging loaded onto a moving truck.

It’s one of the many puzzling aspects of a case investigators will examine in the coming weeks as they try to piece together the timeline of the capsule’s movements from January 12, when it was packaged for transport, to February 1, when a recovery team found it by the side of the road.

The capsule – just 8 millimeters by 6 millimeters – was used in a density gauge fitted to a pipe at Rio Tinto’s Gudai-Darri iron ore mine to measure the flow of material through the feeder.

Rio Tinto said in a statement Monday the capsule was packaged for transit to Perth, 1,400 kilometers (870 miles away), with its presence inside the package confirmed by a Geiger counter before it was transported by a third-party contractor.

Normally, the trip would take more than 12 hours by road, but roughly two hours in, the capsule exited the vehicle as it traveled south, and somehow crossed one lane of traffic, to end up two meters (6.5 feet) from the northbound side of the two-lane highway.

Lauren Steen, general manager of Radiation Services WA, a consultancy that writes radiation management plans, said industry insiders were just as baffled as the public when they heard the capsule was missing.

“The whole team were scratching our head. We couldn’t figure out what had happened,” said Steen, whose company was not involved in its disappearance.

“If the source had been placed in a certified package and transported under all of the requirements of the code of practice, then it’s an extremely unlikely event – one-in-a-million,” she said.

The truck thought to be carrying the capsule arrived in Perth on January 16, four days after its departure from the Gudai-Darri iron ore mine. But it wasn’t until January 25, when workers from SGS Australia went to unpack the gauge for inspection, that it was discovered missing.

In a statement, SGS Australia said it had been hired by Rio Tinto to package the capsule but it had nothing to do with its transportation, which was carried out by a “specialist transporter.”

“We performed the contracted service to package the equipment at the mine site and unpackage it following transportation using qualified personnel for our customer in accordance with all standards and regulations,” it said.

“The transportation of the package, organized by our client and delegated to a specialist transporter, was not within the scope of SGS services. Our personnel noticed the loss of the source at our Perth laboratory when opening the package and reported this incident immediately.”

The name of the company contracted to transport the package has not been released.

The missing capsule triggered a six-day search along a stretch of the Great Northern Highway. Then on Wednesday morning, a car fitted with special equipment traveling south of the small town of Newman detected a higher radiation reading. Handheld devices were then used to hone in on the capsule nestled in the dirt.

In Australia, each state has its own laws regarding the handling of radioactive substances and codes of practice that comply with guidelines set by the Australian Radiation and Nuclear Safety Agency (ARPANSA), a government body that works closely with the International Atomic Energy Agency (IAEA) and World Health Organization (WHO).

In Western Australia, the rules are governed by the Radiation Safety Act 1975, which Steen says is well overdue for review. “It hasn’t been rewritten since the 70s, so I think that kind of speaks for itself,” she said.

Steen said over the decades technological advancements had made the use of radiation sources within mining equipment much safer – and because it was safer, devices were being used more frequently. As of 2021, over 150 projects were operating in Western Australia, the hub of the country’s mining exports, according to the state’s Chamber of Minerals and Energy.

Under the Radiation Safety Act 1975, only specially trained and licensed operators can package radioactive substances, but different rules apply to contractors hired to transport it, Steen said.

“Any transport company can transport radioactive material provided they have got the license to do so,” she said.

Under the act that license can be obtained by attending a one-day course and passing a test certified and approved by the regulator.

The licensee must have oversight of a transportation plan submitted to the regulator but does not have to supervise the journey in person. There are no rules about the type of vehicles used for transport.

Steen says clearly something went wrong – and she hopes the results of the investigation will be shared with the radiation community so they can avoid such issues in future.

Discussion has already started about the need for tougher penalties – in WA, mishandling radioactive substances carries a fine of just 1,000 Australian dollars ($714) – a figure described as “ridiculously low” by Australian Prime Minister Anthony Albanese to reporters on Wednesday.

The rules around packaging radiation sources depend on how much radiation they emit. In some cases, the device could be encased in three layers. In the case of the capsule, the gauge could be considered one layer of protection before it was placed into an “overpack,” a container that was likely bolted shut.

In a statement, DFES said when the package was opened the gauge was found to be broken, with one of the four mounting bolts missing. Referring to the capsule, the statement added, “the source itself and all screws on the gauge were also missing.”

One theory investigators may examine is if the gauge broke and the capsule fell out of the overpack through a hole used to secure the lid.

It’s expected to be several weeks before the Radiological Council submits its report to the WA health minister. Meanwhile, Rio Tinto is carrying out its own investigation.

CEO Simon Trott said the company would be willing to reimburse the government for costs associated with the search – if requested.

WA Emergency Services Minister Stephen Dawson said the offer was appreciated but the government would wait for the outcome of the investigation to apportion blame.

He said he didn’t know how much the search had cost but at least 100 people were involved including police, firefighters, health department and defence force personnel.

Staff from the National Emergency Management Agency, the Australian Nuclear and Science Technology Organization and the Australian Radiation Protection and Nuclear Safety Agency also took part.

On Thursday, relieved DFES officials released new images of the capsule being taken to Perth where it will be safely held in a facility.

This time, it traveled in a convoy of enclosed white vehicles – with big stickers warning of the presence of a radioactive substance.

Iranian couple handed prison sentence for dancing in the streets



CNN
 — 

An Iranian couple, both social media influencers, have been given lengthy prison sentences after a video emerged of them dancing in a main square in the capital Tehran.

In a video shared widely on social media, Astiyazh Haghighi, 21, is seen dancing without a headscarf with her fiancé Amir Mohammad Ahmadi, 22, in Azadi Square. The couple posted the video themselves.

Each was charged with “spreading corruption and vice,” and “assembly and collusion with the intention of disrupting national security,” receiving sentences of ten and a half years, according to activist group Human Rights Activists News Agency (HRANA).

However Mizan, a news agency affiliated with Iran’s judiciary, said each individual was sentenced to 5-year prison term on the charges of “assembly and collusion with the intention of disrupting national security.”

The two are accused of encouraging people to assemble and inviting them to riot in an Instagram post made on October 26, Mizan Online also said.

Judge Abolqasem Salavati presided over their case and meted out the sentences, along with a ban on posting videos on social media for two years and a ban on leaving the country for two years, according to HRANA.

Security forces first raided the couple’s home in the early morning hours of October 30, a source told CNN, and took them to interrogation and then later transferred them to prison.

Haghighi was initially sent to Evin prison’s Ward 209 but then transferred to Qarchak women’s prison where she is currently detained, HRANA reports. Both Haghighi and her partner are being denied access to a lawyer, it added.

Haghighi and Ahmadi each has close to a million followers on Instagram and also have separate YouTube channels with a total of more than half a million followers.

This comes after the country has been roiled in nationwide protests over the death in custody of Mahsa Amini, a young woman accused of flouting the country’s compulsory hijab laws. Iran has cracked down by executing protesters, accused of killing security forces, which critics say were the result of hasty sham trials.

Their lengthy sentences have been compared by critics to that of Sajjad Heydari, an Iranian man who notoriously beheaded his wife last year. Heydari, who killed his 17-year-old wife in February 2022, was sentenced to just eight years and two months in prison, according to the country’s semi-official Khabar Online website.

Lackluster supernova reveals a rare pair of stars in the Milky Way

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.



CNN
 — 

An unusual star system created more of a fizz and less of a bang when it exploded in a supernova.

The lackluster explosion, known as an “ultra-stripped” supernova, led researchers to discover the two stars 11,000 light-years away from Earth.

It’s the first confirmed detection of a star system that will one day create a kilonova – when neutron stars collide and explode, releasing gold and other heavy elements into space. The rare stellar pair is believed to be one of only about 10 like it in the Milky Way galaxy.

The discovery was a long time coming.

In 2016, NASA’s Neil Gehrels Swift Observatory detected a large flash of X-ray light, which originated from the same region in the sky where a hot, bright Be-type star was located.

Astronomers were curious if the two could potentially be linked, so data was captured using the Cerro Tololo Inter-American Observatory’s 1.5-meter telescope in northern Chile.

One of those interested in using this data to learn more about the star was Dr. Noel D. Richardson, now an assistant professor of physics and astronomy at Embry-Riddle Aeronautical University.

In 2019, Clarissa Pavao, an undergraduate student at the university, approached Richardson while taking his astronomy class to ask if he had any projects she could work on to gain experience with astronomy research. He shared the telescope data with her and throughout the pandemic, Pavao learned how to work with the data from the telescope in Chile and clean it up to reduce distortion.

“The telescope looks at a star and it takes in all the light so that you can see the elements that make up this star — but Be stars tend to have disks of matter around them,” Pavao said. “It’s hard to see directly through all that stuff.”

She sent her initial results — which resembled something like a scatterplot — to Richardson, who recognized that she had pinned down an orbit for the double-star system. Follow-up observations helped them verify the orbit of the binary star system, named CPD-29 2176.

But that orbit wasn’t what they were expecting. Typically, binary stars whirl around one another in an oval-shaped orbit. In CPD-29 2176, one star orbits the other in a circular pattern that repeats about every 60 days.

The two stars, a larger one and a smaller one, were whirling around one another in a very close orbit. Over time, the larger star had begun to shed its hydrogen, releasing material onto the smaller star, which grow from 8 or 9 times the mass of our sun to 18 or 19 times the mass of our sun, Richardson said. For comparison’s sake, our sun’s mass is 333,000 times that of Earth.

The main star became smaller and smaller while building up the secondary star — and by the time it had exhausted all of its fuel, there wasn’t enough to create a massive, energetic supernova to release its remaining material into space.

Instead, the explosion was like lighting a dud firework.

“The star was so depleted that the explosion didn’t even have enough energy to kick (its) orbit into the more typical elliptical shape seen in similar binaries,” Richardson said.

What remained after the ultra-stripped supernova was a dense remnant known as a neutron star, which now orbits the rapidly rotating massive star. The stellar pair will remain in a stable configuration for about 5 to 7 million years. Because both mass and angular momentum were transferred to the Be star, it releases a disk of gas to maintain balance and make sure it doesn’t rip itself apart.

Eventually, the secondary star will also burn through its fuel, expand and release material like the first one did. But that material can’t be easily piled up on the neutron star, so instead, the star system will release the material through space. The secondary star will likely experience a similar lackluster supernova and turn into a neutron star.

Over time — that is, likely a couple billion years — the two neutron stars will merge and eventually explode in a kilonova, releasing heavy elements like gold into the universe.

“Those heavy elements allow us to live the way that we do. For example, most gold was created by stars similar to the supernova relic or neutron star in the binary system that we studied. Astronomy deepens our understanding of the world and our place in it,” Richardson said.

“When we look at these objects, we’re looking backward through time,” Pavao said. “We get to know more about the origins of the universe, which will tell us where our solar system is headed. As humans, we started out with the same elements as these stars.”

A study detailing their findings published Wednesday in the journal Nature.

Richardson and Pavao also worked with physicist Jan J. Eldridge at the University of Auckland in New Zealand, an expert on binary star systems and their evolution. Eldridge reviewed thousands of binary star models and estimated there are likely only 10 in the entirety of the Milky Way galaxy similar to the one in their study.

Next, the researchers want to work on learning more about the Be star itself, and hope to conduct follow-up observations using the Hubble Space Telescope. Pavao is also setting her sights on graduating — and continuing to work on space physics research using the new skills she has acquired.

“I never thought I would be working on the evolutionary history of binary star systems and supernovas,” Pavao said. “It’s been an amazing project.”

Hong Kong is criminalizing CBD as a ‘dangerous drug’ alongside heroin


Hong Kong
CNN
 — 

Two years ago, cannabidiol was booming in Hong Kong. The compound, known as CBD, was popping up in cafes, restaurants and stores, with businesses eager to join an exciting new market already well-established in countries around the world.

That all came to an end on Wednesday, when CBD was criminalized in the city and declared a “dangerous drug” on the same level as heroin and fentanyl.

CBD is a chemical found in hemp and marijuana plants. It’s non-psychoactive, meaning it won’t get you high; instead, CBD is often marketed for everything from helping to relieve pain and inflammation to reducing stress and anxiety.

It has surged in global popularity in recent years, with brands adding it to shampoos, drinks, body oils, gummy bears and dog treats. In the United States and Europe, you might find it sold in coffee shops and farmers’ markets, mom-and-pop and high-end department stores, and even drugstore chain CVS.

But last June, draft legislation banning CBD was introduced to Hong Kong lawmakers, and went into effect February 1.

Under the new legislation, possession and consumption of any amount of CBD is punishable by seven years in prison and a fine of 1 million Hong Kong dollars ($127,607). Manufacturing, importing or exporting CBD is punishable by life imprisonment.

Even travelers could face penalties, with the government warning people not to risk “buying these products or bringing them back to Hong Kong.”

The same penalties and conditions apply for cannabis, also known as marijuana.

The ban has forced CBD-focused businesses to close, while other brands have had to roll back or get rid of CBD products.

“It’s a shame because there’s a missed opportunity for sure,” said Luke Yardley, founder of Yardley Brothers Craft Brewery, which had previously sold four products containing CBD – a lager and three nonalcoholic drinks. “I think that anything that you can’t get intoxicated from, and helps you to relax, is probably a good thing.”

The health benefits and risks of CBD have long been debated. In the US, most CBD products are not regulated by the Food and Drug Administration (FDA), which means that people can purchase items off the shelf.

Some research has found that the compound can ease pain and may be useful for those who have trouble sleeping. The FDA has approved one drug with CBD to treat rare, severe forms of epilepsy.

But concerns have also been raised, with some experts saying there isn’t enough scientific research into how CBD works or its potential effects.

In January, the FDA announced CBD products will require a new regulatory pathway in the US, saying: “We have not found adequate evidence to determine how much CBD can be consumed, and for how long, before causing harm.”

In Hong Kong, which has strict cannabis laws, the government’s concern revolves around the possible presence of its sister compound THC (tetrahydrocannabinol) in CBD products. THC is also found in cannabis plants and is responsible for the “high.”

In the US and Europe, CBD products can carry up to 0.3% – a trace amount – of THC, but even that is not acceptable in Hong Kong. And while CBD products could avoid this trace amount by using a pure form of CBD, most manufacturers mix other compounds for higher potency.

From 2019 to early 2022, Hong Kong authorities launched nearly 120 “operations” seizing and testing CBD products from restaurants and shops to warehouses, Secretary for Security Tang Ping-keung said last year. He added that more than 3,800 products were found to contain THC, though did not give further detail on the proportion or percentage of THC in those products.

In a written response to questions raised in the Legislative Council, Tang suggested the government’s traditionally tough stance on THC should be applied to CBD “to protect public heath.”

“We have adopted ‘zero tolerance’ towards drugs and we understand that it is a matter of public concern,” he said. “Therefore, the government plans to control CBD.”

The Action Committee Against Narcotics, a group of representatives from “the fields of social work, education, medical and community service” that advises the government on anti-drug policy, said in a statement last November that it supported the CBD ban and the government’s goal of “a drug-free Hong Kong.”

Many businesses began bracing themselves for regulatory changes in 2022, ahead of the government’s official announcement this January.

Yardley Brothers Craft Brewery stopped making its CBD beverages late last year in anticipation of the ban, and all its leftover products had sold out by December, said Yardley.

He said the CBD drinks had been “very popular,” amounting to roughly 8% of the business, as they offered adults a nonalcoholic option to enjoy when out with friends. At some bars, regulars “come in every weekend for a glass of CBD lemonade,” he said.

Now “there’s less choice for consumers in Hong Kong. That’s not necessarily a step in the right direction,” he said.

Some companies have been forced to shut down completely.

Med Chef, a restaurant that opened in 2021, once boasted of offering Hong Kong’s “first full menu of CBD-infused cocktails, appetizers and entrees.” In a news release during its launch, the restaurant founder emphasized the health and wellness benefits of CBD.

But by early November 2022, it had closed its doors. “We have worked hard in the past to present CBD in its most acceptable form and integrate our food and beverage concepts,” the restaurant wrote in a farewell post on Instagram. “It’s a pity that things didn’t go the way we hoped. Under the latest policies of those in power, we ultimately aren’t able to continue forward with everyone.”

Hong Kong’s first CBD cafe, Found, had also made headlines when it opened in 2020. It sold a variety of CBD products including infused coffee and beers, oils to help sleep, powder to sprinkle into food and pet products to help ease stiff joints.

It closed at the end of September 2022, telling patrons on Instagram that their positive feedback had shown that “CBD could help to cope with the stresses of daily life.”

“Sadly, in spite of the demonstrable positive impact, it has now become apparent that the Hong Kong government intends to adopt new legislation to prohibit the sale and possession of CBD,” it wrote.

Yardley said the government’s concerns about THC were valid – but argued they could have implemented better regulations, such as requiring certifications or standards of safety around CBD samples.

“It’s quite an extreme response to just fully ban it,” he said.

And while the brewery will continue operating, with plans for alternative nonalcoholic beverages to fill the gap, Yardley hopes CBD will be back on the menu. “I hope for the future that it might become legal again,” he said.

This story has been updated to include details of the draft legislation and its introduction.

Myanmar coup anniversary: A world looks away from country’s descent into horror



CNN
 — 

Content warning: This story contains descriptions of violence against children and images viewers may find disturbing.

Bhone Tayza had been impatient to start school. A broken arm had kept the 7-year-old home while the other kids began their lessons, but now that his cast was off, he couldn’t wait to join in.

His mother, Thida Win, was still worried. “Just stay home for today,” she recalls telling her son on his third day back at school last September – but he went anyway.

Hours later, the airstrike hit.

Thida Win was home, in the central Sagaing region of Myanmar, when army helicopters began firing “heavy weapons” including machine guns near her house, she said. She took cover until the shooting stopped, then sprinted to the nearby school, frantic. She finally found Bhone in a classroom, barely alive in a pool of blood, next to the bodies of other children.

“He asked me twice, ‘Mom, please just kill me,’” she said. “He was in so much pain.” Surrounded by armed soldiers of Myanmar’s military who had swarmed the school grounds, she pulled Bhone into her lap, praying and doing her best to comfort him until he died.

He was one of at least 13 victims, including seven children, in the September attack – and among the thousands killed nationwide since the military seized power in a coup on February 1, 2021.

The junta ousted democratically elected leader Aung San Suu Kyi, who was later sentenced to 33 years in jail during secretive trials; cracked down on anti-coup protests; arrested journalists and political prisoners; and executed several leading pro-democracy activists, drawing condemnation from the United Nations and rights groups.

Two years on, the Southeast Asian country is being rocked by violence and instability. The economy has collapsed, with shortages of food, fuel and other basic supplies.

Deep in the jungle, rebel groups have taken the fight to the military. Among their number are many teenagers and fresh graduates, whose lives and ambitions have been upended by a war with no end in sight.

For months after the coup, millions across Myanmar took part in protests, strikes and other forms of civil disobedience, unwilling to relinquish freedoms won only recently under democratic reforms that followed decades of brutal military rule.

They were met with a bloody crackdown that saw civilians shot in the street, abducted in nighttime raids and allegedly tortured in detention.

CNN has reached out to Myanmar’s military for comment. It has previously claimed in state media it is using the “least force” and is complying with “existing law and international norms.”

Since the coup, at least 2,900 people in Myanmar have been killed by junta troops and over 17,500 arrested, the majority of whom are still in detention, according to advocacy group Assistance Association for Political Prisoners (AAPP).

Though mass protests have faded, allegations of atrocities by military troops – including the school strike in the village of Let Yet Kone – continue to emerge.

Daw Aye Mar Swe, a teacher at the school, said she ushered students into classrooms as the military helicopters approached, shortly before the horror descended.

The airstrike hit the roof, sending debris falling all around them. The room filled with dark smoke – and then the soldiers arrived.

They began “shooting at the school for an hour nonstop … with the intention to kill us all,” she told CNN.

She shoved her students under beds for cover, but it was of little use. One young girl was shot in the back. As she tried in vain to stem the bleeding, she urged her crying students: “Say a prayer, as only God can save us now.”

When the shooting was over, the soldiers ordered everybody outside, she said. The students huddled together on the school grounds while the soldiers raided the rest of the village and made arrests, said Daw Aye Mar Swe. She recalled seeing Bhone Tayza among the wounded.

The National Unity Government (NUG), Myanmar’s shadow administration of ousted lawmakers, said 20 students and teachers were arrested after the airstrikes.

It’s not clear what happened to them. CNN could not independently verify details of the incident.

At the time, a spokesperson for the military said government forces entered the village of Let Yet Kone to clear rebel “terrorists” and accused the Kachin Independence Army, a rebel group, and the People’s Defence Force (PDF), an umbrella organization of armed guerrillas, of using children as “human shields.”

Thida Win and Daw Aye Mar Swe denied these claims. “There is no PDF here, or shooting (done by the PDF),” the teacher said. “(The military) shoot us without any purpose or research.”

For some bereaved parents, the agony of losing their children was compounded by being denied a proper goodbye.

After the strike, two residents, who declined to be identified due to fears for their security, said the military took the bodies away and buried them in another township several miles away.

Thida Win corroborated this account, saying she had cried and begged the soldiers to “let me bury my son on my own … but they took him away.” When she contacted a military commander the next day, he said Bhone had already been cremated. To this day, she has not collected his ashes, saying she would not sign any documents issued by the junta that killed her son.

“There are no words … my heart is broken into pieces,” she said.

In between these large-scale attacks, smaller battles are unfolding every day between the military and rebel groups that have sprouted up across the country, allying themselves with long-established ethnic militias.

Some of these groups effectively control parts of Myanmar out of the junta’s reach – and many are composed of young volunteers who left behind families and friends, for what they say is the future of their nation.

Shan Lay, 20, was a high school senior when the coup took place. Now, he spends his days on the front lines as a member of the MoeBye PDF Rescue Team, a small group of combat medics that treats and evacuates injured PDF fighters in eastern Myanmar.

It can be a dangerous job; Shan Lay recalled one instance when their vehicle was shot at and destroyed by military soldiers, forcing the team to jump from the car and run to safety.

Another member of the rescue team, Rosalin, a former nurse, described once hiding in what was supposed to be a secret clinic. The building had been surrounded by junta soldiers and aircraft were circling overhead, so the team waited for nightfall so they could escape in the dark. “I thought I was going to die, and I was ready to relinquish my life,” she said.

CNN is referring to Shan Lay and Rosalin by their “revolution names,” aliases many in the resistance movement adopt for their safety.

Videos of their daily operations, shared by the rescue team, reveal improvised tools and treacherous conditions. Often, they wear no helmets or protective gear, ducking gunfire in just flip flops, t-shirts, long pants and backpacks.

The clips show the group carrying injured fighters on rocky dirt paths, and providing medical care during bumpy rides on pickup trucks; sometimes they have nothing more than boiled water to sterilize wounds, Rosalin said.

When the fighting lulls, they treat injured civilians displaced from their homes and distribute food.

Their jobs are made more difficult by the remote terrain, choppy telecommunications, and unpredictable dangers. When they spoke to CNN over Zoom in January, they had hiked to a higher altitude for better phone service, and were running late after responding to a PDF fighter who had lost his foot after stepping on a land mine.

Rosalin said the junta left them no choice but to fight back after crushing their peaceful protests.

“We know we may have to give up our lives. But if we don’t fight like this, then we know we won’t get democracy, which is what we want,” she said. “As long as this dictatorship is present and we do not have democracy, this revolution will continue.”

Even those not on the front lines have found other ways to resist; there are underground hospitals and schools operating out of the junta’s view, and people have boycotted goods or services related to the junta.

“It’s a remarkable, remarkable show of courage and determination by people,” said Tom Andrews, the UN Special Rapporteur on the situation of human rights in Myanmar.

However, despite the rebels’ best efforts, it’s a desperately uneven fight. And after two years of conflict, their funds and resources are dwindling.

“Before, we had our own homes and pots, we had our own rice, we had some of our money,” said Rosalin. “But we had to leave behind our homes and go live in the jungle.” Finding food and accommodation is challenging, she added.

Shan Lay said some people had sold their houses and land to buy weapons and bullets – but it’s still not enough, and a difficult road lies ahead.

The fighting “is more violent” now, he said. “(The junta) are using larger weapons than before.”

Resources are slim in other rebel bases too, with footage from Myanmar’s eastern Karenni state showing uniformed youth training in the mountains, making homemade ammunition in jungle workshops and storing the rounds in refrigerators.

The pictures are a far cry from the military’s powerful arsenal of tanks and warplanes.

The junta demonstrated its devastating firepower just weeks after the school attack with one of its deadliest airstrikes on record.

Crowds had gathered in the A Nang Pa region of Myanmar’s northern Kachin state to celebrate the 62nd anniversary of the Kachin Independence Organization (KIO), the political wing of the rebel Kachin Independence Army (KIA).

Though the event was organized by the KIO, it was aimed at the public, with artists, singers, religious figures and industry leaders invited, according to a businessman who attended. He described a day of festivities, with people bathing in a stream, playing golf and eating noodles under teak trees before watching a musical performance by a famous singer.

When the airstrike happened, “It was like the end of the world,” the businessman said. Footage of the moment of impact, shared with CNN by the KIO, show people sitting around tables facing the stage when there came a dazzling light and loud crash – followed by flashes of orange light, then darkness.

“I heard people crying, speaking and moaning,” said the businessman. “I was standing in a horrific scene.” Bodies appeared to be everywhere; he saw people trapped under debris and some who had lost limbs.

Videos of the aftermath show buildings reduced to rubble and body bags lined up on the ground.

CNN is not naming the businessman for his safety.

The strike killed up to 70 people, according to the KIO. CNN cannot independently verify the number.

When CNN requested comment from the junta regarding the attack, CNN’s email – and an official response – were published in the government-owned Global New Light of Myanmar newspaper. Military spokesperson Maj. Gen. Zaw Min Tun claimed responsibility for the attack, calling it a necessary military operation targeting “a den where enemies and terrorists were hiding.” He also claimed the military had “never attacked civilians,” calling such reports “fake news.”

KIO leaders deny this. They say the venue was a day’s walk from the nearest KIA battalion, and though some KIO members were in uniform at the event, they were not carrying weapons or military equipment.

Andrews, the UN special rapporteur, also cast doubt on the junta’s claim of not striking civilians. “That statement is absurd,” he told CNN in January. “There is clear evidence we have of airstrikes on villages.”

As millions of civilians in Myanmar grapple with their grim post-coup reality, much of the world looks the other way.

“It has been two years of the devastation of the military junta and the military at war with its own people,” Andrews said. “We’ve seen 1.1 million people displaced, more than 28,000 homes destroyed, thousands of people have been killed.”

The economy is in freefall, with Myanmar’s GDP contracting 18% in 2021. While the World Bank forecasts a slight uptick to 3% growth in 2022, some experts say this is “wildly over-optimistic.”

About 40% of the population were living under the poverty line last year, “unwinding nearly a decade of progress on poverty reduction,” the World Bank said last July. Prices for basic goods like food and fuel have skyrocketed.

But little support has come from the outside. The European Parliament passed a motion in 2021 supporting the NUG as “the only legitimate representatives of the democratic wishes of the people of Myanmar,” and it remains one of the few places that has done so. But no military aid has followed.

Though the European Union and other governments have provided funding for humanitarian aid, relief remains limited. Groups such as the Red Cross say their operations on the ground have been hindered by fighting and financial challenges. In a December report, the UN Office for the Coordination of Humanitarian Affairs (OCHA) said its response plan for Myanmar was “drastically underfunded,” amounting to $290 million out of the $826 million required.

The conflict “has been forgotten,” Andrews said, contrasting the international community’s muted response to Myanmar versus the rush to provide weapons, funding and other assistance to Ukraine in its war against Russia.

The Ukraine model could be applied to Myanmar, he added – not in terms of importing weapons, but in taking “coordinated actions such as economic sanctions that target the junta’s source of revenue, that target their weapons, that target the raw materials that they’re using to build weapons inside the country.”

Andrews pointed to signs that the junta is struggling too, which makes international aid all the more critical for turning the tide. There are reports the military controls less than half of the country and that its operations are suffering from financial difficulties, thanks in part to sanctions already in place, he said. But more is still needed.

“If (the conflict) remains in the shadows of international attention, then we are providing a death sentence to untold numbers of people,” Andrews warned.

Thida Win, the mother of Bhone Tayza, had a similar plea. She is still grieving the loss of a son she described as studious, intelligent and kind, for whom she “had so much hope.”

“I want to ask the world to support us so our children’s death will not be in vain,” she said. “Will you just look away from us? How many kids have to risk their lives?”

Ultraprocessed foods linked to ovarian and other cancer deaths, study finds

Editor’s Note: Sign up for CNN’s Eat, But Better: Mediterranean Style. Our eight-part guide shows you a delicious expert-backed eating lifestyle that will boost your health for life.



CNN
 — 

Eating more ultraprocessed foods raises the risk of developing and dying from cancer, especially ovarian cancer, according to a new study of over 197,000 people in the United Kingdom, over half of whom were women.

Overly processed foods include prepackaged soups, sauces, frozen pizza and ready-to-eat meals, as well as hot dogs, sausages, french fries, sodas, store-bought cookies, cakes, candies, doughnuts, ice cream and many more.

“Ultra-processed foods are produced with industrially derived ingredients and often use food additives to adjust colour, flavour, consistency, texture, or extend shelf life,” said first author Dr. Kiara Chang, a National Institute for Health and Care Research fellow at Imperial College London’s School of Public Health, in a statement.

“Our bodies may not react the same way to these ultra-processed ingredients and additives as they do to fresh and nutritious minimally processed foods,” Chang said.

However, people who eat more ultra-processed foods also tend to “drink more fizzy drinks and less tea and coffee, as well as less vegetables and other foods associated with a healthy dietary pattern,” said Duane Mellor, a registered dietitian and senior teaching fellow at Aston Medical School in Birmingham, UK, in an email.

“This could mean that it may not be an effect specifically of the ultra-processed foods themselves, but instead reflect the impact of a lower intake of healthier food,” said Mellor, who was not involved in the study.

The study, published Tuesday in the journal eClinicalMedicine, looked at the association between eating ultraprocessed foods and 34 different types of cancer over a 10-year period.

Researchers examined information on the eating habits of 197,426 people who were part of the UK Biobank, a large biomedical database and research resource that followed residents from 2006 to 2010.

The amount of ultraprocessed foods consumed by people in the study ranged from a low of 9.1% to a high of 41.4% of their diet, the study found.

Eating patterns were then compared with medical records that listed both diagnoses and deaths from cancer.

Each 10% increase in ultraprocessed food consumption was associated with a 2% increase in developing any cancer, and a 19% increased risk for being diagnosed with ovarian cancer, according to a statement issued by Imperial College London.

Deaths from cancers also increased, the study found. For each additional 10% increase in ultraprocessed food consumption, the risk of dying from any cancer increased by 6%, while the risk of dying from ovarian cancer rose by 30%, according to the statement.

“These associations persisted after adjustment for a range of socio-demographic, smoking status, physical activity, and key dietary factors,” the authors wrote.

When it comes to death from cancer among women, ovarian cancer is ranked fifth, “accounting for more deaths than any other cancer of the female reproductive system,” noted the American Cancer Society.

“The findings add to previous studies showing an association between a greater proportion of ultra-processed foods (UPFs) in the diet and a higher risk of obesity, heart attacks, stroke, and type 2 diabetes,” said Simon Steenson, a nutrition scientist at the British Nutrition Foundation, a charity partially supported by food producers and manufacturers. Steenson was not involved in the new study.

“However, an important limitation of these previous studies and the new analysis published today is that the findings are observational and so do not provide evidence of a clear causal link between UPFs and cancer, or the risk of other diseases,” Steenson said in an email.

People who ate the most ultraprocessed foods “were younger and less likely to have a family history of cancer,” Chang and her colleagues wrote.

High consumers of ultraprocessed foods were less likely to do physical activity and more likely to be classified as obese. These people were also likely to have lower household incomes and education and live in the most underprivileged communities, the study found.

“This study adds to the growing evidence that ultra-processed foods are likely to negatively impact our health including our risk for cancer,” said Dr. Eszter Vamos, the study’s lead author and a clinical senior lecturer at Imperial College London’s School of Public Health in a statement.

This latest research is not the first to show an association between a high intake of ultraprocessed foods and cancer.

A 2022 study examined the diets of over 200,000 men and women in the United States for up to 28 years and found a link between ultraprocessed foods and colorectal cancer — the third most diagnosed cancer in the United States — in men, but not women.

And there are “literally hundreds of studies (that) link ultraprocessed foods to obesity, cancer, cardiovascular disease, and overall mortality,” Marion Nestle, the Paulette Goddard professor emerita of nutrition, food studies and public health at New York University told CNN previously.

While the new UK-based study cannot prove causation, only an association, “other available evidence shows that reducing ultra-processed foods in our diet could provide important health benefits,” Vamos said.

“Further research is needed to confirm these findings and understand the best public health strategies to reduce the widespread presence and harms of ultra-processed foods in our diet,” she added.

Green comet will swing by Earth for the first time in 50,000 years

 — 

A recently discovered green comet will soon zip by Earth for the first time in 50,000 years. It was last visible in the night sky during the Stone Age.

Discovered on March 2, 2022, by astronomers using the Zwicky Transient Facility’s wide-field survey camera at the Palomar Observatory in San Diego County, California, the comet made its closest approach to the sun on January 12, according to NASA.

Named C/2022 E3 (ZTF), the comet has an orbit around the sun that passes through the outer reaches of the solar system, which is why it’s taken such a long route — and long time — to swing by Earth again, according to The Planetary Society.

The icy celestial object will make its closest pass by Earth between February 1 and February 2, around 26 million miles to 27 million miles (42 million kilometers to 44 million kilometers) away, according to EarthSky.

Even during its closest approach, the comet will still be more than 100 times the moon’s distance away from Earth, according to EarthSky.

As the comet nears Earth, observers will be able to spot it as a faint green smudge near the bright star Polaris, also called the North Star. Comets reflect different colors of light due to their current positions in orbit and chemical compositions.

Early morning skies, once the moon has set after midnight for those in the Northern Hemisphere, are optimal for viewing the comet. The space object will be more difficult to see for those in the Southern Hemisphere.

Depending on its brightness, C/2022 E3 (ZTF) may even be visible to the unaided eye in dark skies, but binoculars or a telescope will make the comet easier to see.

The comet can be distinguished from stars by its streaking tails of dust and energized particles, as well as the glowing green coma surrounding it.

The coma is an envelope that forms around a comet as it passes close to the sun, causing its ice to sublimate, or turn directly to gas. This causes the comet to look fuzzy when observed through telescopes.

After passing by Earth, the comet will make its closest approach of Mars on February 10, according to EarthSky.

If clouds or inclement weather get in the way of skywatching, The Virtual Telescope Project will share a livestream of the comet in the skies above Rome. And don’t miss the other celestial events to see in 2023.

Orbiter captures image of a bear’s face on Mars

Sign up for CNN’s Wonder Theory science newsletter. Explore the universe with news on fascinating discoveries, scientific advancements and more.



CNN
 — 

As a NASA orbiter turned its camera to the Martian surface, the face of a bear seemed to be looking back.

A camera aboard the Mars Reconnaissance Orbiter, called the High Resolution Imaging Experiment, or HiRISE, captured an image of the unusual geological feature in December.

A circular fracture pattern on the Martian surface shapes the head, while two craters resemble eyes. A V-shaped collapse structure creates the illusion of the nose of a bear.

The circular fracture might be due to the settling of a deposit on top of a buried impact crater that had been filled in with lava or mud. The noselike feature is possibly a volcanic vent or a mud vent.

The University of Arizona, which developed the camera with Ball Aerospace, shared the image on January 25.

The photo is reminiscent of another celestial “face” glimpsed by a NASA space observatory in October 2022, when the sun appeared to smile due to dark spots called coronal holes.

And last March, the Curiosity rover spotted a rock formation that resembled a flower on Mars.

The HiRISE camera has been taking images of Mars since 2006, when the Mars Reconnaissance Orbiter began circling the red planet. The powerful camera was designed to capture detailed images of the Martian surface, including features as small as 3 feet (1 meter).

The orbiter circles Mars every 112 minutes, flying from about 160 miles (255 kilometers) above the south pole to 200 miles (320 kilometers) over the north pole.

The spacecraft and its suite of instruments help NASA scientists study the Martian atmosphere, weather and climate, and how they change over time. The orbiter searches for evidence of water, ice and complex terrain and scouts future landing sites for other missions.

Most recently, the orbiter returned stunning images of what winter looks like on Mars.
