Metabolism doesn’t slow down in middle age: shocking study

Packing on the poundage? Sorry, suckers: We can’t use middle age as our excuse for that spread anymore!

A revelatory new study has determined that metabolism, long thought by most of humankind to decline progressively during adulthood, is actually stabilized between the ages of 20 and 60 — when it actually starts tanking.

An international team of killjoy researchers, whose work was published Friday in the journal Science, discovered that metabolism is at its highest in infants — naturally — who burn calories about 50% faster than adults. That rate declines yearly by about 3% until they reach the age of 20 or so, when metabolism plateaus through middle adulthood. At 60, the slump returns at a depressing rate of about 1% more per year until we drop dead.

What this means: We can no longer blame middle age as the primary reason for amassing newfound weight. For accuracy, researchers accounted for metabolic differences in volunteers, such as body size muscle to fat composition.

“Metabolic rate is really stable all through adult life, 20 to 60 years old,” said study author Herman Pontzer, an associate professor of evolutionary anthropology at Duke University, who spoke to NBC News on Thursday about the research.

Pontzer went on to pontificate about new data that’s likely to send a shiver down the lucrative wellness industry’s collective spine:

“There’s no effect of menopause that we can see, for example. And you know, people will say, ‘Well when I hit 30 years old, my metabolism fell apart.’ We don’t see any evidence for that, actually,” said Pontzer. His new book, “Burn” (Avery) is about new frontiers in bariatric health.

At 60, the metabolic rate slumps full-force — about 1% more per year until death. Also, “there’s no effect of menopause that we can see, for example,” study author Herman Pontzer said. “You know people will say, ‘Well when I hit 30 years old, my metabolism fell apart.’ We don’t see any evidence for that, actually.”

As part of a global experiment, 6,400 participants, aged 8 days to 95 years were asked to perform “doubly labeled water” test, in which some of the hydrogen and oxygen atoms were replaced with their isotopes, making their pathway easily traced through urine samples.

“By calculating how much hydrogen you lose per day, and how much oxygen you lose per day, we can calculate how much carbon dioxide your body produces every day,” Pontzer explained to NBC News. “And that’s a very precise measurement of how many calories you burn every day, because you can’t burn calories without making carbon dioxide.”

The findings, said Pontzer, were a long time coming as scientists now have access to such a large test group.

Pontzer also said, “This was the first time that we had the ability to do this with a really big data set that would allow us to pull apart the effects of body size and age and gender and all these things on our energy expenditures over the day.”

The study is shedding new light on how our cells age, indicating that our metabolism has less to do with physical activity and more with our biology.

“People thought, ‘Well, maybe it’s because you’re less active, or maybe it’s because people tend to lose muscle mass as they get into their 60s, 70s and older,’ ” said Pontzer. “But we can correct for all those things. We can say, ‘No, no, no, it’s more than that.’ It’s that our cells are actually changing.”

In an editorial published in tandem with the study, University of Wisconsin geriatrics researchers Timothy Rhoads and Rozalyn Anderson suggest that the study results point to a link with age-related diseases, such as Alzheimer’s, often appearing around 60.

“The [health] decline from age 60 is thought to reflect a change in tissue-specific metabolism, the energy expended on maintenance,” they wrote, according to NBC News. “It cannot be a coincidence that the increase in incidence of noncommunicable diseases and disorders begins in this same time frame.”

Shocking video of passenger mutiny over wrongful removal of two Black men from flight

Video caught the moment passengers on an EasyJet flight out of London came together to protest the removal of two Black men from the flight.

The incident occurred on Thursday as a flight was taxiing and preparing for takeoff from London Gatwick Airport to Malaga in Spain. According to passenger Luke Gayle, flight attendants alerted police and had the plane return to the gate to remove two Black men from the flight for “huffing at a member of the crew” when they were asked to put their shoes back on until after takeoff.

As the police came aboard to remove the two men, passengers can be heard protesting on the video, telling the men, “no, don’t get off,” as well as “sit down.”

Following the protests of passengers, the men were permitted to stay on the flight and the flight crew was replaced. However, in a statement to the Daily Mail, EasyJet said the crew was replaced due to them exceeding time limits on their shifts and not because of complaints from the incident.

“EasyJet does not discriminate against any individual. Safety is our highest priority and there is nothing to suggest that discrimination played any part in the issue onboard,” the statement read, adding, “Our crew must ensure that safety requirements are followed by all passengers and as part of their role must check prior to take-off that everyone is compliant with these.” 

EasyJet said it will be investigating the incident.

Virginia girl’s shocking shooting death leads to arrest of teen suspect

A juvenile suspect was reportedly arrested Saturday afternoon following a manhunt connected to the fatal shooting of a Virginia middle school student.

Lucia Bremer was shot multiple times on Friday, forcing a nearby high school in Henrico County, Va., to be placed on a temporary lockdown.

The eighth-grader was taken to a hospital where she died of her wounds, the Richmond Times-Dispatch reported. The suspect was reportedly last seen fleeing the shooting before the manhunt began.

The suspect, who has not been identified because of his age, was taken into custody at a home about a half-mile from where the shooting happened, according to the Henrico Citizen.

The suspect has been charged with second-degree murder, reports said.

VIRGINIA TEEN GIRL DEAD AFTER SHOT MULTIPLE TIMES NEAR HIGH SCHOOL; SUSPECT AT LARGE, REPORTS SAY

“Detectives worked tirelessly throughout the night to follow up on leads provided by our community partners,” Henrico police said while announcing the arrest Saturday. 

Bremer’s family confirmed her death in a statement posted to Facebook on Saturday, writing they were “saddened to report that our beloved daughter and joyful farmer, Lucia Whalen Bremer, was killed in a senseless act of gun violence on March 26,” the Times-Dispatch reported. “Thank you for keeping our family in your thoughts as we navigate the next few weeks.”

Melanie Phipps, principal of Bremer’s Quioccasin Middle School in Richmond, described Lucia as “funny” and ‘wise,” adding that she was “heartbroken and devastated” over her killing.

She said students and staff were planning a virtual gathering for Sunday to grieve Bremer’s loss and the school plans to have an increased police presence Monday so everyone feels safe on a “most difficult day,” according to the Citizen.

David Whitehouse, Bremer’s English teacher said, “In a year of difficult days and weeks, this will be the most difficult of my entire career.”

Bridgewater’s Ray Dalio Warns Government Could Restrict Bitcoin Investments, Impose ‘Shocking’ Taxes – Bitcoin News

The founder and chief investment officer of Bridgewater Associates, the world’s largest hedge fund firm, has warned that the government could “impose prohibitions against capital movements” into assets such as bitcoin. He added that regulators may also impose changes in taxes that “could be more shocking than expected.”

Ray Dalio Warns About Government Prohibitions and Taxes

Ray Dalio, founder and chief investment officer of Bridgewater Associates, wrote a post on Linkedin last week entitled: “Why in the World Would You Own Bonds When…”

He pointed out that the bond markets currently offer “ridiculously low yields,” which “do not meet these asset holders’ funding needs.” The executive wrote, “There is now over $75 trillion of US debt assets of varying maturities,” adding that their holders will at some point want to sell them to get cash to buy goods and services with.

However, Bridgewater’s chief investment officer estimates that “at current valuations, there is way too much money in these financial assets for it to be a realistic expectation that any significant percentage of that bond money can be turned into cash and exchanged for goods and services.” He elaborated: “It has to be accommodated … via printing a lot of money and devaluing it, and restructuring a lot of debt and government finances, usually including large increases in taxes.”

Dalio explained: “Based both on how things have worked historically and what is happening now, I am confident that tax changes will also play an important role in driving capital flows to different investment assets and different locations, and those movements will influence market movements.”

The billionaire fund manager emphasized that “If history and logic are to be a guide, policymakers who are short of money will raise taxes and won’t like these capital movements out of debt assets and into other storehold of wealth assets and other tax domains,” warning:

They could very well impose prohibitions against capital movements to other assets (e.g., gold, bitcoin, etc.) and other locations. These tax changes could be more shocking than expected.

The Bridgewater Associates founder used Elizabeth Warren’s proposed wealth tax as an example, stating that it “is of an unprecedented size.” Citing his study of “wealth taxes in other countries at other times,” he expects this proposal “will most likely lead to more capital outflows and other moves to evade these taxes.”

Consequently, “The United States could become perceived as a place that is inhospitable to capitalism and capitalists,” Dalio opined, emphasizing that “the chances of a sizable wealth tax bill passing over the next few years are significant.” In conclusion, the Bridgewater executive cautioned:

One should be mindful of tax changes and the possibility of capital controls.

Dalio has been studying bitcoin over the recent months. In November last year, he admitted that he may be wrong about bitcoin but was nonetheless worried about governments outlawing cryptocurrency. In December, he said bitcoin could “serve as a diversifier to gold and other such storehold of wealth assets.” Then, in January this year, he said that “bitcoin is one hell of an invention,” revealing that his firm looking closely at the cryptocurrency.

“Shocking” genetic data suggest Ebola lurked in survivor for 5-6 years

Enlarge / A staff member of the N’zerekore hospital lifts his shirt sleeve as he prepares to get his anti-ebola vaccination in N’zerekore on February 24, 2021. Nzerekore Hospital was where the first cases of Ebola were found at the end of January 2021.

The Ebola viruses behind a new outbreak in Guinea are stunningly similar to viruses identified during the massive West Africa outbreak that spanned 2013 to 2016, according to a new genetic analysis. The finding suggests that virus may have silently persisted in a survivor for at least five years and that the current outbreak was sparked by that unlucky person, rather than a spillover from an animal reservoir.

In the genetic analysis posted online Friday, a group of international researchers report that Ebola viruses collected from the current outbreak in Guinea have only a dozen or so genetic differences from Ebola variants collected from the same area of Guinea in 2014. Based on what researchers know about the pace at which Ebola collects such genetic substitutions—its evolutionary rate—that number of accumulated differences should have totaled over 110 in that timespan, not 12.

“This number of substitutions is far less than what would be expected during sustained human-to-human transmission,” they researchers write in their analysis. Instead, they note such a sluggish evolutionary rate is a “hallmark of persistent infections.”

“Therefore, the index case of the 2021 Guinea cluster was likely infected from a persistent source, such as via sexual transmission from an [Ebola] survivor,” they conclude.

The Ebola virus is known to persist in some survivors, particularly in places where it can lay low from the immune system, such as the testicles or eyeballs. A 2016 study reported resurgence of the virus in a survivor’s seminal fluid more than 500 days after the initial infection.

Still, the more than five-year span was “shocking” to many virologists and public health experts. And it raises a variety of concerns for the many survivors of past outbreaks, some of whom may have had mild cases of Ebola without realizing it. In particular, many people known to have survived Ebola face stigmatization, and the possibility of years-long persistence is likely to amplify that problem.

In the 2013-2016 West Africa outbreak, more than 28,000 people were infected with the virus, and over 11,000 died. It is the largest Ebola outbreak in history. Most of the cases and deaths were in Guinea, Liberia, and Sierra Leone. The outbreak began with a case reported in an 18-month old boy in December 2013; the boy is believed to have caught the virus from bats.

The current outbreak, which was declared February 14, has sickened at least 18 and killed nine.  Vaccination efforts are now underway to stop the spread of the virus.

Shocking Mika Zibanejad benching may echo with Rangers

We’d say the last time something like this happened was when John Tortorella benched Marian Gaborik in the third period of Game 5 of the Rangers’ 2012 conference finals against the Devils, except doing such a thing was pretty much standard operating procedure for the coach.

Hence, no shock value there.

This, though, on Thursday night in Newark was different. This was different with David Quinn, who for the first time in his three seasons behind the bench brought down the hammer on one of the Rangers’ marquee players by dramatically reducing Mika Zibanejad’s ice time in the first period before sitting him for the first 10:46 of the second.

Finally, after weeks of giving Zibanejad the benefit of the doubt he had earned not only down the stretch last season, but through the entirety of the center’s work under Quinn, the coach had seen enough, following another period in which The Swede was a cipher on the ice.

And so he sat him. Sat him after a team-wide desultory opening 20 minutes, in which the Devils only could build a 1-0 lead thanks to Igor Shesterkin’s exceptional play in nets, and sat him through the midpoint of the second, by which time the Blueshirts had tied it 1-1 on Chris Kreider’s power-play goal.

Shock value here, all right.

“I didn’t love his game, I didn’t love what we were seeing — I didn’t love a lot about our first period — but obviously he’s had a tough start to the season and maybe sitting him for a while would give him a little jolt and give our team a little jolt,” Quinn said after the Blueshirts stormed back for a 6-1 victory. “I did like what I saw when he came back out.

“I was just going to see how he was playing, how he was competing, how he was skating. If I thought I saw an uptick in his play, I was going to continue to play him and if not, he was going to continue to sit. That’s really what it came down to.”

This was a headline-packed game. Kreider, off on one of his patented Did. You. See. Chris! streaks, recorded his second hat trick within five games, giving him nine goals in the past six matches. Shesterkin, who has elevated his game over the fortnight, was forced to leave with 5:52 remaining after sustaining an apparent right-leg injury that could force him to miss a spell of time. If so, it will have significant ramifications for this 9-9-3 team that has gone 5-2 in the last seven.

But the benching of Zibanejad will reverberate. You never know how a player as prideful as Zibanejad will react to something like this. You also don’t know how his teammates and best buds will react. Let’s not forget. He was one of the best players in the world last season. He was one of the best centers in the league the year before that. And he was benched.

“I think he’s letting the stats and all the pressure slow him down a little bit,” Quinn said. “I think it’s getting to him.

“This is a guy who has been a fearless player, he’s been a courageous player and he still is a guy who gets in the battle but something is just missing. We certainly continued to try and let him play his way through it, he certainly earned that opportunity, but right now we’ve got to continue to play the guys who are playing well.”

Zibanejad played with purpose through his final 13 shifts and 9:05 of ice, continuing to excel on the penalty-kill unit that went 4-for-4 in this one. He was involved, jumped on a free puck to set up Alexis Lafreniere for the dart that made it 6-1 at 18:27 of the third for the freshman’s sixth point (3-3) in the past six games.

(And, whoa boy, Quinn has suddenly gotten so much better at developing youngsters, correct?)

Zibanejad’s decline has been cloaked in mystery. Its long-range, big-picture ramifications are stark. But the small-picture ramifications of this benching will be stark, too. There is no question his mates have his back, with Kreider issuing an unsolicited captain-like testimonial in support of his beleaguered friend and colleague. You could almost hear Mark Messier standing up for Brian Leetch. Almost.

This was a night of significance for the Rangers and for Quinn, who benched a star and whose team responded with 40 dominant minutes in its wake.

“I think anytime you sit one of your top players that certainly gives everybody a bit of a wake-up call and I just thought we got better as the game went on,” the coach said. “If that had something to do with it, I don’t know.”

The Rangers and Quinn had been waiting on Zibanejad for 20 games. The coach didn’t wait for 21. Now we all wait to see how the alternate captain responds to this.

California deputy arrested, accused of staging ‘shocking ambush’

A California sheriff’s deputy was arrested and charged after the district attorney’s office said he staged a “shocking ambush.”

Deputy Sukhdeep Gill, with the Santa Clara County Sheriff’s Office, was taken into custody on Friday and charged with felony vandalism and misdemeanor falsely reporting a crime.

The incident happened last January when just after 10:30 p.m. Gill used the emergency broadcast button on his police radio to report that shots had been fired, according to a release by the district attorney.

Officers from multiple sheriff’s departments responded and a manhunt began for the alleged shooter.

Gill told an officer at the scene that he had parked on the shoulder of a dirt road in Morgan Hill to urinate and as he was walking back to his car, he was shot by a person in a vehicle that had turned its lights off.

Gill said he fired two shots at the vehicle but the car drove away.

The district attorney’s office said that Gill had no serious injuries.

“It appeared he had been shot only once, and in a miraculous spot — his body-worn camera, which was destroyed,” the release stated.

During the investigation into the alleged shooting, Gill’s “story fell apart,” the agency said. Other evidence, including ballistics, also “exposed serious discrepancies in the deputy’s account.”

“This case is bewildering and deeply disappointing,” District Attorney Jeff Rosen said in a statement. “Deputy Gill’s actions abused the trust of his fellow officers and diverted public safety resources away from protecting the community to investigate a made-up crime.”

Gill, 27, could not be reached for comment on Saturday. His attorney, Nicole Pifari, said, “I can tell you we look forward to getting a look at the investigation and the related evidence to understand why these charges are being pursued.”

The deputy has been with the sheriff’s office since 2016. He was placed on administrative leave pending the criminal and administrative investigations.

The Santa Clara County Sherrif’s Office said in a press release that if the allegations against Gill are true, his actions “are not representative of the upstanding men and women of the Sheriff’s Office, who risk their lives every day to serve and protect our community with honesty and integrity.”
