But a big problem persists as long as the coronavirus continues to spread: long COVID. Long COVID is a condition involving new, returning or ongoing health problems four or more weeks after initial coronavirus infection. “The long COVID community and the COVID cautious community are pretty furious about it,” Hennessy says. And of the people who were aware of long COVID, more than 20% said they at least somewhat agreed with the statements “those with Long COVID may just be depressed” and “Long COVID symptoms are often just the normal aches and pains of life.”“They’re told that their brain fog or other symptoms are not real, and that’s demoralizing,” Rylance said. Young adults and children can also have long COVID, with more than 1% of kids ever having long COVID as of 2022, according to a national survey.

What the team discovered while piecing together Vittrup Man’s life is shedding light on the movements and connections between different Stone Age cultures. Vittrup Man was likely born and grew up along the coast of the Scandinavian Peninsula, perhaps within the frigid climes of Norway or Sweden. Studying Vittrup Man has helped researchers gain insights about the genetics, lifestyles and ritual practices that can be traced to Stone Age societies, Sjögren said. A cartoon included with the new research depicts how Vittrup Man was possibly sacrificed in a swamp. But it’s also possible that Vittrup Man was in the wrong place at the wrong time.

CNN —Tardigrades, also known as water bears, commonly survive in some of Earth’s most challenging environments. Under stress in extreme cold or other harsh environmental conditions, tardigrades’ bodies produce unstable free radicals of oxygen and an unpaired electron, aka a reactive oxygen species that can wreak havoc on the body’s proteins and DNA if they overaccumulate. The survival mechanism kicks off when cysteines, one of the amino acids that forms proteins in the body, come into contact with these oxygen free radicals and becomes oxidized, the researchers found. The free radicals become, so to speak, the hammer used to smash the glass on a fire alarm. “We came up with this idea (that) maybe it’s those species that are actually signaling to the tardigrades to enter their tun state,” she said.

Lion attacks: How to stay safe on safaris in Africa
  + stars: | 2024-01-25 | by ( Forrest Brown | ) edition.cnn.com   time to read: +17 min
It was July of 2022, and the co-founder of Discover Africa Safaris was out in the bush near the Khwai River in northern Botswana. African lions are fully capable of attacking, killing and even eating humans, and it’s generally estimated about 250 people a year die in lion attacks. WLDavies/E+/Getty ImagesOnly about 23,000 lions remain in sub-Saharan Africa, found mostly in Eastern and Southern Africa, Muruthi said. Before your trip, It's important to study up on safety tips -- such as remaining inside your safari vehicle when lions and other wild animals approach. Secondly, fleeing indicates to the lion you’re frightened and now possible prey, turning what might have initially been a mock charge to test you into a real attack.

Read previewThe popular Paleo diet is based on the belief that we are better off eating like our ancestors by sticking to a largely meat-heavy diet. "One way to think about it is as soon as anybody tells you that the Paleo diet was one thing, you can stop listening," said Pontzer, who wasn't involved in the study. The paleo diet is a high-protein diet that emphasizes unprocessed foods. AdvertisementThere is no one Paleo dietThis isn't the only research that disproves the model often held up by proponents of the modern-day definition of the Paleo diet.

The footprints, found at several sites in southern Africa, were recently identified as the oldest birdlike tracks ever found, preceding the earliest known skeletal fossils of avians by about 60 million years. Some called the tracks birdlike, but others weren’t so sure. Ellenberger may have muddied the waters by assigning many differently shaped tracks to the ichnogenus, “and not all of them are birdlike,” Abrahams said. They could belong to other reptiles or cousins of dinosaurs that evolved birdlike feet,” Clarke said. During a trip to Maphutseng, a fossil locale in Lesotho, the team found a number of birdlike tracks from the Triassic Period.

That’s what scientists have interpreted from the pose of the dinosaur’s fossil skeleton. The study authors identified it as an alvarezsaurid, a type of small theropod (bipedal meat-eating dinosaur) with a long tail and legs and short front limbs. Alvarezsaurids are part of a larger dinosaur group called maniraptorans, which includes birds and birdlike dinosaurs that were their closest relatives.

How head lice reveal secrets about human origins
  + stars: | 2023-11-13 | by ( Manav Tanneeru | Katie Hunt | ) edition.cnn.com   time to read: +5 min
CNN —Head lice have been constant, if unwanted, human companions for as long as our species has been around. Some 20 years ago, David Reed, a coauthor of the new study and a researcher and curator at the Florida Museum of Natural History, found that human head lice are composed of two ancient lineages, with origins predating Homo sapiens. Doing so allowed researchers to detect the hybrid lice and better capture the genetic diversity of head lice. Ascunce said she had hoped the information they gleaned might answer whether Neanderthal head lice are still around today, but the 15 genetic markers, known as “microsatellites,” that they studied in the lice nuclear DNA didn’t reveal that information. “New ongoing studies are being done using whole genome sequences from human lice, so stay tuned for more exciting research on that.”

CNN —Of all 14,669 varieties of plants and animals found in Europe that were registered on the International Union for Conservation of Nature’s Red List of Threatened Species by the end of 2020, one-fifth of them face the risk of extinction, a new analysis has found. The thousands of species found in Europe that appear on the Red List account for nearly 10% of the continent’s total biodiversity, according to the paper. IPBES originally estimated that 1 million plant and animal species across the world were at risk of extinction, including about half a million insect varieties, based on inferences from Red List data. The data on invertebrates provided by the new analysis suggests the number of species threatened with extinction globally is actually closer to 2 million, Hochkirch said. Hochkirch said he hopes the analysis will spur further conservation action for insects and other threatened species in Europe.

[1/3] A group of chimpanzees listen to other chimpanzees heard at a distance in the West African forests of Cote d'Ivoire, studied as part of research by the Tai Chimpanzee Project, in this undated handout photograph. But in this case, it involved not people but chimpanzees in Tai National Park in southwestern Ivory Coast, West Africa's largest protected area of rainforest. Inter-group violence is ubiquitous in chimpanzees, Lemoine said. They were more likely to advance into dangerous territory after descending a hill if the rival chimpanzees were further away. Chimpanzees and the closely related bonobos are the species nearest genetically to humans, sharing about 98.8% of our DNA.

It is a scenario that has unfolded innumerable times in the history of human warfare. Inter-group violence is ubiquitous in chimpanzees, Lemoine said. While atop border hills, the chimpanzees typically refrained from noisily eating or foraging, instead resting and listening. They were more likely to advance into dangerous territory after descending a hill if the rival chimpanzees were further away. Chimpanzees and the closely related bonobos are the species nearest genetically to humans, sharing about 98.8% of our DNA.

“They are way smarter than you think,” Ms. Hillemacher said. Now, in a study published in the journal PLOS One on Wednesday, Ms. Hillemacher and her colleagues say they have found evidence that roosters can recognize themselves in mirrors. The mirror test is a common, but contested, test of self-awareness. The mirror test has since been used to assess self-recognition in many other species. But different cognitive processes are active in different situations, and there’s no reason to think that the mirror test is accurate for animals with vastly different sensory abilities and social systems than what chimps have.

The scientists found large whales such as humpbacks and North Atlantic right whales were among the most vulnerable to climate change, and that other toothed whales and dolphins were also at high risk. The scientists looked at the animals' degree of exposure to climate change and sensitivity and capacity to adapt to it. “The U.S. is one of the most data-rich countries when it comes to marine mammals, and those data should be driving what are arguably some of the world’s strongest laws to protect marine mammals," she said. But the way climate change affects the giant animals is global in nature, so the broader approach is helpful, she said. Climate change also could affect the distribution and behavior of marine mammals, the study states.

Being a vegetarian might be in your DNA
  + stars: | 2023-10-04 | by ( Madeline Holcombe | ) edition.cnn.com   time to read: +4 min
The study published Wednesday in PLOS One found that there are four genes associated with how well someone is able to adhere to a vegetarian lifestyle. Several of the genes that the study found to be associated with vegetarianism had to do with metabolizing lipids, Yaseen said. Although this study may not provide a definitive answer, it is an important look into nutrition, he said. “This study shines a light on a relatively under-explored area of research: the genetics behind dietary preferences,” Ordovás said. “The association of genetic variants with long-term strict vegetarianism suggests a biological basis for this dietary choice, beyond just cultural, ethical, or environmental reasons.”

CNN —Researchers working at a cave in southern Spain have found evidence that the skeletal remains of ancient humans buried there were dug up, modified and even used as tools by subsequent generations. While these types of remains are known as “skull cups,” that doesn’t necessarily mean they were used as containers, Milella said. “Modification and manipulation of human remains are indeed well known for this time, with examples also from the same region. In that sense, Marmoles Cave is consistent with what we know about the funerary behavior of these cultures,” he said. And it is also possible that those who modified the remains may have known the people that they belonged to when they were alive.

Almost 6,000 years ago, communities used a cave in Spain as a burial place. AdvertisementAdvertisementScraping and cutting of these bones left traces "that can only be attributed to human action," Martínez Sánchez said. "The actions of fragmenting and manipulating the bones may well be related to specific ritual events performed inside the cave," Martínez Sánchez said. "They're often viewed as sort of passageways to another world to the ancestors, to other kinds of worlds that are seen as sacred liminal spaces, spaces that are somewhere in between the land and the living and the land of the ancestors," she said. There's a chance they may have disturbed the human remains as well.

Scientists are studying a new threat emerging from melting permafrost: ancient viruses. The authors of the study — published in PLOS Computational Biology, a peer-reviewed scientific journal — used computer simulations to model how ancient viruses could survive, evolve, and persist in our modern-day communities. This research marks the first "extensive exploration of the ecological risk" these viruses pose, according to the authors. In many of the simulations conducted in the study of the ancient viruses, researchers found that they could thrive in modern communities without making a catastrophic impact, but still caused "non-negligible ecological change." This means the viruses most likely to re-emerge successfully could also be the most likely to pose an ecological risk.

CNN —Modified skulls found in an ancient burial site in Japan were deliberately reshaped in both men and women as an expression of collective identity. It’s possible, the researchers suggested, that the Hirota cranial reshaping played a part in their trading success. For the new study, the scientists 3D-scanned and digitally modeled 19 adult Hirota skulls to conduct more detailed morphological analysis. Certain indentations were also identified in Hirota skulls but were absent in those of Jomon and Doigahama individuals. At the Hirota site, each marker indicates where burials were found along with the notes on their sex and approximate age group.
