Feeling older than you are? It could be how you sleep
  + stars: | 2024-03-26 | by ( Sandee Lamotte | ) edition.cnn.com   time to read: +5 min
CNN —Not getting enough sleep may cause you to feel five to 10 years older than you really are, according to two new studies. A lack of energy and motivation can certainly contribute to feeling older while limiting a person’s ability to remain physically and socially active, both of which contribute to feeling young, Balter said. For every night of poor sleep during that time, people reported feeling about a quarter of a year older than their chronological age. “These findings support that sleep, a vital biological phenomenon, might hold the key to feeling young,” Balter and her colleagues wrote in the study. “If you suspect that your sleep deprivation is due to a sleep disorder such as insomnia or sleep apnea, it’s crucial to seek evaluation and treatment from a healthcare professional,” he said.

A neutron star is the collapsed core of a supergiant star that's gone supernova. Pulsar neutron stars, like the one astronomers believe SN 1987A left behind, emit pulses of X-rays. AdvertisementStudying SN 1987A has deepened astronomers' understanding of supernovae and the role they play in our ever-evolving universe. Before JWST, astronomers lacked a telescope powerful enough to observe the compact object that SN 1987A left behind. Advertisement"We interpreted this as being conclusive evidence that the emission lines we were seeing were the result of radiation from the neutron center," Kavanagh said.

Sea otters eat constantly and one of their favorite snacks is the striped shore crab. Researchers found that the return of the crab-eating sea otters to a tidal estuary near Monterey, California, helped curb erosion. Hunting bans and habitat restoration efforts helped sea otters recover some of their former range. For the new study, researchers analyzed historic erosion rates dating back to the 1930s to assess the impact of sea otters' return. Other research has shown that sea otters help kelp forests regrow by controlling the number of sea urchins that munch kelp.

These ghost clouds look beautiful, but they are a visible sign of deadly air pollution. Of all of the theories, however, the impact of shipping regulations is swiftly becoming one of the most discussed. But this is not an argument against cutting air pollution, Diamond said, it’s an argument for tackling it alongside reducing carbon emissions. The cooling impact of air pollution is far outweighed by the heating impact of burning fossil fuels. It’s when air pollution is tackled without also reducing carbon emissions, that “we can get into trouble,” Diamond said.

Snoozers have the same sleep quality when they wake up immediately vs. when they snooze, a new study found. In fact, when people were allowed to snooze for 30 minutes, they were actually more alert. This contradicts what people previously thought about snoozing, that it hurts sleep quality. Next, the scientists closely monitored 31 regular snoozers in the lab to see what effects snoozing had on their sleep quality. AdvertisementAdvertisementThe test results found no serious physical differences in sleep quality between the two scenarios.

But this study marked the first time that RNA - much less stable than DNA - has been recovered from an extinct species. While not the focus of this research, the ability to extract, sequence and analyze old RNA could boost efforts by other scientists toward recreating extinct species. The Tasmanian tiger resembled a wolf, aside from the tiger-like stripes on its back. The last-known Tasmanian tiger succumbed in a Tasmanian zoo in 1936. Private "de-extinction" initiatives have been launched aimed at resurrecting certain extinct species such as the Tasmanian tiger, dodo or woolly mammoth.

CNN —A spate of Quran-burning protests in Sweden and Denmark has caused angry demonstrations in Muslim-majority countries, heightened security fears at home and left both Scandinavian nations questioning whether they need to review their liberal laws on freedom of speech. But both countries signaled Sunday that they are exploring legal ways to prevent such protests, amid security and geopolitical concerns. While freedom of speech has long been a constitutional right in Sweden and Denmark, the scrapping of blasphemy laws was a more recent development. But neither country tightened their free speech laws in response to these attacks. “Sweden is right now the target of influence campaigns, supported by states and state-like actors, whose purpose is to harm Sweden and Swedish interests,” said Bohlin.

VILNIUS, Lithuania (AP) — Turkish President Recep Tayyip Erdogan on Monday introduced a new condition for approving Sweden's membership in NATO, calling on European countries to "open the way" for Turkey to join the European Union. It was the first time that Erdogan linked his country's ambition to join the EU with Sweden's efforts to become a NATO member. The White House readout of the Biden-Erdogan call did not mention the issue of Turkish membership in the EU. Sullivan didn't mention the EU membership issue. Previously non-aligned Sweden and Finland applied for NATO membership last year following Russia's invasion of Ukraine.

CNN —For the first time, astronomers have assembled a glowing portrait of the Milky Way galaxy using cosmic “ghost particles” detected by a telescope embedded in Antarctica’s ice. Over the years, astronomers have showcased stunning images of the Milky Way through electromagnetic radiation from visible light or radio waves. These tiny, high-energy cosmic particles are often referred to as ghostly because they are extremely vaporous and can pass through any kind of matter without changing. The IceCube detector is seen under a starry night sky, with the Milky Way appearing over low auroras in the background. Cosmic rays are mostly made up of protons or atomic nuclei that have been stripped from atoms, according to NASA.

But a child born in poverty in America is more likely to face poverty in adulthood than in many Western countries. Recent research shows that's more likely to happen in Denmark, Germany, Australia, and the UK. Their finding: "Intergenerational poverty in the U.S. is four times stronger than in Denmark and Germany, and twice as strong as in Australia and the UK." Bocconi University, Rockwool Foundation and Stockholm UniversityThis table shows what the researchers call "intergenerational persistence of poverty" across five countries. So yes, you're more likely to experience the American Dream in many countries outside the US.

Experiencing negative changes in workplace leadership and fairness was associated with the strongest long-term impact on a worker's sleep. LumiNola/E+/Getty ImagesSleep problems included initiating or maintaining sleep, poor-quality sleep and daytime tiredness two to four times a week that lasted one month to three months. Within a two-year period of time, over half of the participants (53%) reported changes in their workplace environment. However, if the changes at work were negative, sleep issues increased — in fact 1 in 4 people in the study with a worse job environment developed problems getting enough rest. Having negative changes in the leadership and fairness sector was associated with the greatest long-term impact on sleep, more than negative changes in coworker relationships or collaboration, the study found.
BACKGROUNDRussia's invasion of Ukraine in February last year convinced Sweden and Finland to ditch long-held policies of military non-alignment. WHY DOES TURKEY OBJECT TO SWEDISH NATO MEMBERSHIP? Unlike Turkey, Hungary does not have a list of demands, but says grievances need to be addressed before it can ratify Sweden's accession to NATO. WHEN WILL TURKEY AGREE TO SWEDISH NATO MEMBERSHIP? NATO Secretary-General Jens Stoltenberg has said it would be inconceivable that the alliance would not support Sweden if it were threatened.
Hazardous "forever chemicals" called PFAS are contaminating drinking water, food, and air. It may be impossible to completely avoid PFAS, but there are a few simple ways to reduce your exposure. A 2019 study found that people had lower PFAS levels in their blood after eating at home, and higher levels after eating fast food or at restaurants. A few types of water filters can diminish PFAS levels, though they may not completely remove the chemicals from the water. It was previously updated to reflect disagreements in the scientific community about the degree of PFAS exposure from Teflon.
WHY DOES TURKEY OBJECT TO SWEDISH AND FINNISH MEMBERSHIP? The PKK is designated a terrorist group in Turkey, Sweden, the United States and Europe. Sweden and Finland want to proceed together, but with Turkey's ire directed mainly at Sweden, Finland could eventually lose patience with the process. COULD NATO EXPEL TURKEY, ALLOWING SWEDEN AND FINLAND TO JOIN? But Sweden, Finland and NATO want to avoid a long drawn-out process.
Researchers proposed it takes 4 days of quality sleep to recover from just 1 hour of sleep debt. Why it's hard to catch up on sleepPsychiatrist and sleep medicine expert, Dr. Alex Dimitriu, is of the mindset that you can catch up on sleep, but only if you haven't let your sleep debt grow too great. By definition, one hour of sleep lost equals one hour of sleep debt. "If the sleep debt is greater, the time to recover becomes markedly longer, and complete recovery may not be possible, so it's important to not let sleep debt go too far," Dimitriu, founder of Menlo Park Psychiatry & Sleep Medicine, told Insider. How to pay back sleep debtPaying back sleep debt is like paying back credit card debt: Try to pay all, or as much, of the total balance so that the debt doesn't grow too large.
NEW YORK — Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. With animal fossils hard to come by, the researchers extracted environmental DNA, also known as eDNA, from soil samples. Studying really old DNA can be a challenge because the genetic material breaks down over time, leaving scientists with only tiny fragments. In their study, published Wednesday in the journal Nature, they compared the DNA to that of different species, looking for matches. He worked on the study that previously held the “oldest DNA” record, from a mammoth tooth around a million years old.
CNN —A core of ice age sediment from northern Greenland has yielded the world’s oldest sequences of DNA. They then compared the DNA fragments with existing libraries of DNA collected from both extinct and living animals, plants and microorganisms. It was super exciting when we recovered the DNA (to see) that very, very different ecosystem. They found no DNA from carnivores but believe predators — such as bears, wolves or even saber-toothed tigers — must have been present in the ecosystem. Further study of environmental DNA from this time period could help scientists understand how various organisms might adapt to climate change.
CNN —Wolves are pack animals, living in family groups led by a matriarch and her mate. Researchers found that gray wolves in Yellowstone National Park infected with a parasite known as Toxoplasma gondii were more likely to leave the group of wolves they were born into or become a pack leader. Kira Cassidy/NPSRisky behavior of infected animalsScientists have been monitoring wolves in Yellowstone National Park since the species was reintroduced there in 1995. Pack behavior is observed via trail cameras and plane flyovers, and about a quarter of the wolves wear radio tracking collars and undergo blood tests. “The more we learn about wolf behavior, the better we can understand how to conserve the species,” she said.
