Shock wave from sun has opened up a crack in Earth’s magnetic field, and it could trigger a geomagnetic storm
A mysterious shock wave in a gust of solar wind has sent a barrage of high-speed material smashing into Earth’s magnetic field, opening up a crack in the magnetosphere. The barrage of plasma could lead to a geomagnetic storm today (Dec. 19), according to spaceweather.com.
The shockwave’s origins aren’t exactly known, but scientists think it could have come from a coronal mass ejection launched by the sunspot AR3165, a fizzing region on the sun’s surface that released a flurry of at least eight solar flares on Dec. 14, causing a brief radio blackout over the Atlantic Ocean.
Sunspots are areas on the sun’s surface where powerful magnetic fields, created by the flow of electrical charges, knot into kinks before suddenly snapping. The resulting release of energy launches bursts of radiation called solar flares, or plumes of solar material called coronal mass ejections (CMEs). Once launched, CMEs travel at speeds in the millions of miles per hour, sweeping up charged particles from the solar wind to form a giant, combined wavefront that (if pointed toward Earth) can trigger geomagnetic storms.

Geomagnetic storms occur when energetic solar debris (mostly consisting of electrons, protons and alpha particles) gets absorbed by, and subsequently compresses, Earth’s magnetic field. The solar particles zip through the atmosphere near the poles where Earth’s protective magnetic field is weakest and agitate oxygen and nitrogen molecules — causing them to release energy in the form of light to form colorful auroras such as the northern lights.
The storms can also create cracks in the magnetosphere which remain open for hours at a time, enabling some solar material to stream through and disrupt satellites, radio communications, and power systems.
Thankfully today’s potential storm, predicted to be a G-1 class, will be fairly weak. It may cause minor fluctuations in power grids and impair some satellite functions — including those for mobile devices and GPS systems. It could also cause an aurora to appear as far south as Michigan and Maine.
More extreme geomagnetic storms, however, can have far more serious effects. They can not only warp our planet’s magnetic field powerfully enough to send satellites tumbling to Earth, but can disrupt electrical systems and even cripple the internet.
The upcoming storm is just the latest in a string of solar attacks fired at Earth as the sun ramps up into the most active phase of its roughly 11-year solar cycle.
Astronomers have known since 1775 that solar activity rises and falls in cycles, but recently, the sun has been more active than expected, with nearly double the sunspot appearances predicted by the National Oceanic and Atmospheric Administration.
Scientists anticipate that the sun’s activity will steadily climb for the next few years, reaching an overall maximum in 2025 before decreasing again.
The largest solar storm in recent history was the 1859 Carrington Event, which released roughly the same energy as 10 billion 1-megaton atomic bombs. After slamming into Earth, the powerful stream of solar particles fried telegraph systems around the world and caused auroras brighter than the light of the full moon to appear as far south as the Caribbean.
If a similar event were to happen today, scientists warn it would cause trillions of dollars’ worth of damage, trigger widespread blackouts, and endanger thousands of lives. A previous solar storm in 1989 released a billion-ton plume of gas that caused a blackout across the entire Canadian province of Quebec, NASA reported.
But this may not even scratch the surface of what our star is capable of hurling at us. Scientists are also investigating the cause of a series of sudden and colossal spikes in radiation levels recorded in ancient tree rings across Earth’s history. A leading theory is that the spikes could have come from solar storms 80 times more powerful than the Carrington Event, but scientists have yet to rule out some other potentially unknown cosmic source.
Scientists crack aging mystery: Gene length is the deciding factor
Scientists believe they’ve cracked the secret of aging.
A major genetic analysis of people, rodents and fish found the length of their DNA was directly linked to their biological age.
Shorter genes were associated with shorter lifespans, while longer genes were linked to better health and longevity.
Scientists believe if they can hijack this mechanism, it could pave the way for a fountain of youth drugs that could slow — or even reverse — aging.
Dr Thomas Stoeger, lead author of the study from Northwestern University in Illinois, said: ‘I find it very elegant that a single, relatively concise principle seems to account for nearly all of the changes in the activity of genes that happen in animals as they age.’
Scientists said having longer genes can lead someone to live longer (stock photo)
The length of a gene is based on the number of nucleotides within it. Each string of nucleotides translates to an amino acid, forming a protein.
Therefore a very long gene yields a large protein, and a short gene yields a small protein. A cell needs to have a balanced number of small and large proteins to achieve homeostasis, and problems occur when that balance gets out of whack.
In the study, researchers looked at genetic data from several large datasets, including the Genotype-Tissue Expression Project, a National Institutes of Health-funded tissue bank that archives samples from human donors for research purposes.
The research team first analyzed tissue samples from mice, rats and killifish of various ages.
In all animals, the researchers noticed subtle changes to thousands of different genes across samples.
This means that not just a small subset of genes that contributes to aging. Aging, instead, is characterized by systems-level changes.
This view differs from prevailing biological approaches that study the effects of single genes.
Since the onset of modern genetics in the early 20th century, many researchers expected to be able to attribute many complex biological phenomena to single genes.
And while some diseases, such as hemophilia, do result from single gene mutations, the narrow approach to studying single genes has yet to lead to explanations for the myriad changes that occur in neurodegenerative diseases and aging.
After completing their animal research, the researchers turned their attention to humans. They looked at changes in human genes from ages 30 to 49, 50 to 69 and then 70 and older.
Measurable changes in gene activity according to gene length already occurred by the time humans reached middle age.
‘There already seems to be something happening early in life, but it becomes more pronounced with age,’ Dr Stoeger said.
‘It seems that, at a young age, our cells are able to counter perturbations that would lead to an imbalance in gene activity. Then, suddenly, our cells can no longer counter it.’
Northwestern’s Luis Amaral, a senior author of the study, said: ‘The result for humans is very strong because we have more samples for humans than for other animals.
‘It was also interesting because all the mice we studied are genetically identical, the same gender and raised in the same laboratory conditions, but the humans are all different.
‘They all died from different causes and at different ages. We analyzed samples from men and women separately and found the same pattern.’
But the scientists found that with aging activity within cells shifts towards shorter genes, upsetting the balance.
This is counterbalanced in people with very long genes, because they have longer proteins available in cells.
Dr Stoeger said: ‘The changes in the activity of genes are very, very small, and these small changes involve thousands of genes.
‘We found this change was consistent across different tissues and in different animals.’
Scientists hope the study — published in Nature Aging — will spur the development of therapies to slow or reverse aging.
Currently, medications target symptoms rather than the causes of getting older which the Northwestern experts said was like using painkillers to reduce a fever.
Dr Amaral said: ‘Fevers can occur for many, many reasons. It could be caused by an infection, which requires antibiotics to cure, or caused by appendicitis, which requires surgery.
‘Here, it is the same thing. The issue is the gene activity imbalance. If you can help correct the imbalance, then you can address the downstream consequences.’
Watch man ‘having the time of his life’ smoking crack on subway
This straphanger is going off the rails.
A man caught on video smoking what appears to be crack on a city subway train has social media abuzz and New Yorkers fired up.
“Oh man!” shouts the wired, bug-eyed passenger after lighting up and sucking on a glass pipe.
“Check him out, y’all. He having the time of his life!” observes the video-taker in the 23-second clip shot aboard an uptown 4 train last month.
The pepped-up passenger — wearing a blue surgical mask around his forehead — then spins around, stands against the subway doors and shouts, “Ayo, damn man!”
A peeved passenger with a buzzcut stares straight ahead during the floor show while others put some distance between themselves and the apparent crackhead.
“That shouldn’t be happening on the train. It’s just crazy,” said Mine Bah, a 23-year-old rapper and Bronx Community College student who posted the October video to his Instagram Malcolmx_2 last month. The Brooklyn man told The Post a pal recorded the incident and he posted it from the phone. The post has over 38,000 likes.
Joked lady__d88: “My guy [buzzcut man] just sitting next to him breathing it in too trying to catch a hit 😭😭😭.”
“This was non-existent before the 2020 lockdowns. Now it happens daily,” replied Ministry of Otaku.
Activist Jason Curtis Anderson tweeted the video on Thursday, snarking, “Is smoking crack on the subway even a crime anymore?”
Martin Scorsese might be taking another crack at Gangs Of New York
There’s always more Martin Scorsese news. No matter what’s happening in the world, you can bet your bottom dollar that we, the entertainment media, won’t miss the opportunity to talk about America’s patron saint of movie takes so hot they set the internet ablaze. And when the 79-year-old filmmaker is not criticizing the culture’s box office obsession or having Guillermo Del Toro come to his aid, he’s making film art. Lots of it. In addition to finishing up Killers Of The Flower Moon, attempting to keep Devil In The White City on track, and releasing a documentary about David Johansen of the New York Dolls, he’s also heading back to New York.
According to Deadline, Scorsese will direct the first two episodes of a Gangs Of New York television series. Written by playwright and Shantaram writer Brett Leonard and based on Herbert Asbury’s 1927 book, the series will not follow Scorsese’s 2002 film, which starred Leonardo DiCaprio, Cameron Diaz, or Daniel Day-Lewis. Yes, dear reader, if you can believe it, Daniel Day-Lewis will not be coming out of retirement for prestige television.
As noted by Deadline, this is the second attempt at apdapting Scorsese’s Oscar-nominated historical epic to TV. In 2013, he announced a series that would’ve focused on Gang Of Chicago and Gangs Of New Orleans in addition to New York. “This time and era of America’s history and heritage is rich with characters and stories that we could not fully explore in a two-hour film,” Scorsese said at the time of that announcement. “A television series allows us the time and creative freedom to bring this colorful world, and all the implications it had and still does on our society, to life.”
When Scorsese will have the time for this is anyone’s guess. His latest documentary, Personality Crisis: One Night Only, premiered at the New York Film Festival last night. First, however, he needs to recast Keanu Reeves and replace Todd Field, both of whom dropped out of Devil In The White City last week.
NFL Week 5 Power Rankings: All hail the NFC East (for now), as Cowboys crack top 10, Giants make sizable leap
Before the season, most laughed at the NFC East.
NFC Least, they said.
A month into the season, nobody is laughing now. The last remaining undefeated team in the league is the 4-0 Philadelphia Eagles, fresh off a comeback victory in the slosh over the Jacksonville Jaguars on Sunday. They remain atop my Power Rankings this week, but there are two other 3-1 teams in the NFC East.
The Dallas Cowboys, who have won three straight games with backup quarterback Cooper Rush, and the New York Giants, who somehow find themselves with three victories despite being anything but pleasing to the eyes, are both one game behind the Eagles.
The Cowboys have the look of a team that will stay there, with a big game against Philadelphia on the road looming in two weeks after a tough one with the Los Angeles Rams this week. The Giants don’t have that same look, but coach Brian Daboll deserves a ton of credit for getting this team off to a fast start. We will know a lot more about the Giants this week when they play the Green Bay Packers in London this Sunday.
For now, the top of the division is a combined 10-2, with only the 1-3 Washington Commanders dragging the division down, with two of their losses having come to the Eagles and the Cowboys.
The Eagles are the story for now. They faced the NFL’s best run defense in the Jaguars and ran through them for over 200 yards in the rain. They rallied from 14-0 down to win, 29-21, thanks to a fierce pass rush combined with that run game.
Quarterback Jalen Hurts didn’t put up gaudy numbers, but he again played a big part in the victory, which is why he’s smack dab in the middle of the MVP conversation.
The Cowboys are winning with defense and some timely throws by Rush. But any talk of a quarterback controversy when Dak Prescott is back healthy is absurd. It’s Prescott’s team and the Cowboys will be much better when he’s back.
As for the Giants, they’ve taken the old-school approach to winning, which is running the football and playing sound defense. Thanks to the resurgence of Saquon Barkley, who leads the league in rushing, the Giants have the top-ranked run offense in the league. They are also ninth in scoring defense.
At times, the Giants are ugly to watch. There is no dynamic passing game, but the old-time football has them at 3-1. I doubt they can continue to win without improving the passing game, which could be tough with their top two quarterbacks banged up. But the start deserves praise.
So, for now, let’s hail the NFC East — and especially the Eagles.
Biggest Movers

|---|---|---|---|---|
1 |

After a slow start, they showed how good they are in rallying to beat the Jaguars. They are the clear top team in the league. | — | 4-0-0 |
2 |
|
That was a big-time, comeback victory against the Ravens on the road. That speaks volumes about this team. | 1 | 3-1-0 |
3 |
|
Going to Tampa Bay and beating up on the Bucs gets them back on track after that loss to the Colts. They looked like the Chiefs offense of old in that game. | 2 | 3-1-0 |
4 |
|
They have to be better than what they showed against the Patriots, or they won’t be winning games against better teams down the road. The run defense isn’t good right now. | — | 3-1-0 |
5 |
|
The Tua Tagovailoa situation clouds their fast start. It’s Teddy Bridgewater this week against the Jets, which will be a tougher game than maybe they thought. | 3 | 3-1-0 |
6 |
|
The defense carried this team the first three weeks, but got beat up against the Chiefs. They haven’t played a complete game yet. | — | 2-2-0 |
7 |
|
At 3-1, they are in first place after a victory over the Saints in London. The good news is they got Justin Jefferson back on track. The defense, though, has to be better. | 4 | 3-1-0 |
8 |
|
Cooper Rush has done a great job in place of Dak Prescott as the Cowboys have won three straight. The defense is carrying the team. | 5 | 3-1-0 |
9 |
|
That defense is outstanding, even with guys missing time. DeMeco Ryans is doing a great job, and they looked like a playoff team against the Rams. | 6 | 2-2-0 |
10 |
|
They just don’t look good right now. Matt Stafford isn’t playing well behind a bad offensive line and they lack playmakers not named Cooper Kupp. | 3 | 2-2-0 |
11 |
|
Their defense is awful right now, which limits their chances to win. That is not a Ravens team we’ve come to expect. | 3 | 2-2-0 |
12 |
|
They’ve won two straight in typical Titans fashion: Using their toughness. They have righted things since that Bills debacle. | 4 | 2-2-0 |
13 |
|
They evened up their record by beating Miami, but now face a big division game at Baltimore. They still don’t seem to be clicking on offense just yet. | 5 | 2-2-0 |
14 |
|
They showed well early against the Eagles, but then fell apart. Trevor Lawrence has to be better, and really has to do a better job of taking care of the football. | 5 | 2-2-0 |
15 |
|
They did some good things on offense against the Texans, bouncing back from that Jaguars loss. They still need to be better on defense. | 5 | 2-2-0 |
16 |
|
At 3-1, they are one of the early surprises of this season. They don’t win pretty, but they find a way. The quarterback injuries are concerning. | 7 | 3-1-0 |
17 |
|
The injuries have impacted their defense, but they had their chances against the Falcons. Now 2-2, they haven’t looked like a playoff team yet. | 5 | 2-2-0 |
18 |
|
At 2-2, they haven’t come close to looking like the team many expected. They’ve been just off on both sides of the ball at different times this season. | 4 | 2-2-0 |
19 |
|
At 1-2-1, they are limping into their Thursday night game with the Broncos. The Jonathan Taylor injury situation bears watching. | 2 | 1-2-1 |
20 |
|
At 2-2, they had to have the road game at Carolina and they got it with an impressive second half. Now they face the league’s top team in the Eagles at home in prove-it game. | 1 | 2-2-0 |
21 |
|
They faced a must-win game against the Broncos, and they won it. Maybe that’s the game that gets this team going, but now they get the Chiefs on the road. | 4 | 1-3-0 |
22 |
|
At 2-2, they are tied for first place in their division. Give Arthur Smith credit for this team’s start. | 4 | 2-2-0 |
23 |
|
They showed a lot of fight against Green Bay after being forced to play Bailey Zappe at quarterback because of injuries. But they are limited in a lot of ways. | 3 | 1-3-0 |
24 |
|
Injuries have hurt them a lot, but at 1-3 they are one of the early-season disappointments. The good news is nobody is running away with the division. | 3 | 1-3-0 |
25 |
|
They can’t pass the football or protect their quarterback. That limits what they can do, which looks like it will be a season-long problem. | 1 | 2-2-0 |
26 |
|
Zach Wilson looked good in his first game back from injury, which is encouraging for the future. Robert Saleh has this team heading in the right direction. | 1 | 2-2-0 |
27 |
|
Geno Smith is playing outstanding football at quarterback. Their offense has become fun to watch. The defense has issues. | 4 | 2-2-0 |
28 |
|
It’s Kenny Pickett time now, which is a good thing. But at 1-3, this might be a season for him to learn and grow and not about wins and losses. | 6 | 1-3-0 |
29 |
|
They are fun to watch since they score a lot, but that defense is awful. They can’t stop anybody, which is going to make for a long season. | 1 | 1-3-0 |
30 |
|
The Baker Mayfield experiment just isn’t working. He is playing poorly, and this team could be headed for a coaching change. | 1 | 1-3-0 |
31 |
|
They have lost three straight and have looked bad in doing so. Are changes coming, both with starters and coaches? | 1 | 1-3-0 |
32 |
|
They showed something in coming back against the Chargers, but they aren’t good enough to win games like that. This is going to be a long season. | — | 0-3-1 |

Rupee Hits All-Time Low As Major Currencies Crack Against Dollar
The rupee hit a new all-time low against the dollar, marking the third straight session of record low levels breached, plunging well past 81.50 per dollar on Monday as the greenback rose sharply to multi-year highs against most major currencies on fears of a global recession from the rising borrowing rates worldwide.
Bloomberg quoted the rupee last changing hands at 81.5038 per dollar, after opening at its weakest level of 81.5225 and hitting a record low of 81.5587, compared to its Friday’s close of 80.9900.
PTI reported that the domestic currency fell 38 paise to an all-time low of 81.47 against the US dollar in early trade.
“The panic is created by the dollar index which witnesses strong buying as a strong hedge against interest rate hikes and inflation cycle. The rupee downtrend will continue as long as positive triggers are not witnessed from the inflation forefront,” Jateen Trivedi, Vice President – Research Analyst at LKP Securities, told ANI.
“The next trigger for the rupee next week is the RBI policy which shall provide some respite to the rupee fall. The rupee range can be seen between 80.50-81.55 before RBI policy,” he added.
Later in the week, the Reserve Bank of India is set to raise rates too, but by how much has split policy watchers widely.
Due to the RBI’s market intervention to protect the weakening rupee and for the country’s trade settlement, India’s foreign exchange reserves have been steadily declining for the past few months. Another potential explanation for the rupee’s decline is this depletion.
The Indian rupee is likely to remain weaker as investors expect that the US Fed will continue to hike interest rates aggressively to cool inflation, Sriram Iyer, Senior Research Analyst at Reliance Securities, told PTI.
“Focus now shifts to RBI’s meeting this week, with its decision due on Friday. We expect RBI to hike rates by 50 bps to cool stubbornly high inflation and prevent the currency from weakening further,” Mr Iyer added.
Interest rate hikes in the United States and an aggressive policy stance by the Federal Reserve forced a dozen other nations to do so last week, underscoring global economic slowdown risks, which has led to the onslaught of relentless sell-off in global financial markets and a dollar rally.
The dollar rally is also a reflection of investors increasing flight-to-safety bets as Asian markets risk experiencing crisis-level stress again, as two of the most significant currencies in the region have collapsed under the assault of unrelenting dollar strength – the yen and the yuan.
Due to the widening gap between the ultra-hawkish Federal Reserve and the dovish policymakers in China and Japan, the yuan and the yen are falling.
The drop in the yuan (renminbi) and the yen is making matters worse for everyone and endangering the region’s reputation as a top destination for risk investors. At the same time, other Asian countries heavily rely on their foreign exchange reserves to offset the effects of the dollar.
“The renminbi and yen are big anchors, and their weakness risks destabilizing currencies to trade and investments in Asia,” Vishnu Varathan, head of economics and strategy at Mizuho Bank, told Bloomberg.
“We’re already heading toward global financial crisis levels of stress in some aspects; then the next step would be the Asian financial crisis if losses deepen,” he added.
If the decline in the currencies of the two largest economies in the region causes foreign investors to withdraw money from Asia, a full-fledged crisis could develop.
The declines could spark a vicious cycle of competitive devaluations, a drop in demand, and a loss of consumer confidence.
“Currency risk is a bigger threat for Asian nations than interest rates,” Taimur Baig, chief economist at DBS Group in Singapore, told Bloomberg. “At the end of the day, all of Asia are exporters, and we could see a reprise of 1997 or 1998 without the massive collateral damage.”
Not just Asian currencies, the dollar’s ascent has pushed the British pound to a new lifetime low, and analysts are now calling for a sterling parity with the dollar.
The pound led declines among major currencies Monday, slumping to a record low, and the euro wobbled to a two-decade low at $0.9660 as war risks escalated in Ukraine before steadying at $0.9696.
Other currencies, too, were nursing losses, as reflected by a dollar gauge hitting a record high, with the Aussie currency touching $0.6510, its lowest since mid-2020.
“It’s a king US dollar — we’ve been seeing currencies across Asia come under pressure,” Sian Fenner, senior Asia economist for Oxford Economics, said on Bloomberg TV. “It’s adding to inflationary pressures and more central banks raising rates more than we have historically seen.”
Indian scientists crack giant puzzle behind dwarf galaxies
How do small galaxies — the basic building blocks of the universe — gather masses?
The ill-understood cosmic process can now become clearer to scientists thanks to a group of Indian astronomers who have provided a crucial link in drawing the bigger picture of galaxy growth and evolution.
Using India’s first space observatory Astrosat, astrophysicists at Inter University Centre for Astronomy and Astrophysics (IUCAA), Pune, and their collaborators in the USA and France have shown how the star-forming entities on the outskirts of a dwarf galaxy migrate towards the central region of the galaxy, contributing to its growth in mass and luminosity.
Thanks to high-quality telescopes, scientists’ grasp on big galaxies like the Milky Way or Andromeda has improved in the last two decades. The Milky Way, for instance, is known as one of the giant galaxies with billions of stars, even though very little star formation is happening currently.
But giant galaxies are surrounded by tens of dwarf galaxies — irregular in shape, often forming stars. Their mass could be 50 times lower than the Milky Way. How such dwarf and giant galaxies assemble their stars and evolve is still one of the major puzzles.
IUCAA scientist Kanak Saha, his PhD student Anshuman Borgohain and their partners in Observatoire de Paris, IBM Watson Research Division and Tezpur University along with a veteran Indian astronomer decided to probe the problem with 17 hours of observational data captured by Astrosat’s Ultraviolet Imaging Telescope.
“We got evidence that these galaxies are accreting matter from outside. We witnessed the ‘live’ formation of these farway dwarf galaxies!” Saha told DH.
The team looked at 11 blue dwarf galaxies that are 1.3-2.8 billion light years away. The key challenge was to detect such faint, extremely blue, star-forming clumps that were too far away to see although they have a million solar masses of material within them.
“The UltraViolet Imaging Telescope’s resolving power and deep-field imaging techniques have been the key to spotting some very young, large star-forming clumps. They form on the periphery and then spiral into the galaxy within a specific time, adding to the growth of the galaxy,” said Saha.
A good part of the research work consists of meticulously calculating the time required for the star forming clumps to migrate inside the galaxy. The time span, according to Saha, could be one-tenth of the life of a galaxy or within a billion year.
“It has been a mystery how some small galaxies can have such active star formation,” said team member Bruce Elmegreen of IBM Watson Research Division, USA, adding that such observations suggest accreting gas in the far outer parts can be forced to move towards the centre because of the inward pull exerted by giant gas and stellar complexes.
The findings appeared last week in Nature.
A Crack Stayed Opened in Earth’s Magnetic Field for 14 Hours

On Thursday, July 7, 2022, photographs in the United States and Canada had the chance to capture a stunning sight. A crack opened in Earth’s magnetic field which lasted for nearly 14 hours, allowing solar winds to enter and cause a colorful aurora in the sky.
While a crack in the magnetic field sounds dangerous, it is actually quite normal. “We’ve discovered that our magnetic shield is drafty, like a house with a window stuck open during a storm,” Harald Frey, lead author of a study on this discovery back in 2003, says. This phenomenon is caused by co-rotating interaction region (CIR) from the Sun, which is sometimes launched in Earth’s direction.
However, while most magnetic fields are thought to last a short amount of time, this one endured for several hours, leading to a G1-class geomagnetic storm. Fortunately, however, this event did not cause any power outages or issues with satellites—which can sometimes occur during these cracks in the magnetic field. Instead, the leaked solar winds produced beautiful northern lights in the U.S. and Canada.
On Thursday, July 7, the Earth experienced a crack in its magnetic field which lasted 14 hours.

This allowed people in the U.S. and Canada the opportunity to see beautiful northern lights in the sky.
Often I manage to capture the aurora when the kP is 2, this morning was one of those times. With asolar wind of 334 km/s one would think not. But the CIR shock is what’s important, and being out there when it occurs thank you’s to @SNHWx @Vincent_Ledvina @nenecallas @halocme pic.twitter.com/BIm2ggNXm2
