  • First Europeans 'weathered Ice Age'

    11/07/2014 2:56:57 AM PST · by Natufian · 14 replies
    BBC ^ | 11/6/2014
    The genetic ancestry of the earliest Europeans survived the ferocious Ice Age that took hold after the continent was initially settled by modern people. That is the suggestion of a study of DNA from a male hunter who lived in western Russia 36,000 years ago. His genome is not exactly like those of people who lived in Europe just after the ice sheets melted 10,000 years ago. But the study suggests the earliest Europeans did contribute their genes to later populations.

    A genetic analysis of a 45,000-year-old thigh bone narrows down the time when modern humans and Neanderthals first interbred.A 45,000-year-old leg bone is raising questions about just how close modern-day humans are to our thick-browed Stone Age ancestors. DNA from the femur of a Siberian man is helping to pinpoint when modern humans and Neanderthals first interbred, researchers say. But what does this mean for the human connection to a species that disappeared nearly 30,000 years ago? The thigh bone, spotted six years ago on the banks of the Irtysh River in Siberia by a Russian artist who carves jewelry...

    Britons are to be the first in the world to test a new vaccine against the deadly ebola virus. Altogether 60 healthy volunteers will be given the vaccine next month in a trial led by Oxford University scientists. If the vaccine performs as well in humans as in monkeys, the trial will be extended to 80 people in The Gambia and in Mali. The entire trial programme is being fast-tracked – subject to ethical approval – with the intention of using the vaccine in people at high risk in West Africa early next year.

    An international team of scientists conducting an analysis of the genetic diversity and cranial measurements of 10 African and Asian human populations conclude that anatomically modern humans may have dispersed out of Africa earlier than previously thought, and in more than one stage: initially into Asia by taking a southern route through Arabia as much as 130,000 years ago; and later into Northern Eurasia on a more northerly route 50,000 years ago. The timing and nature of early modern human dispersal out of Africa has long been disputed among scholars, with competing theories or models about how and when it...

    What makes for a beautiful visage, and why, may have been discovered accidentally on a Russian fur farm BEAUTY, the saying has it, is only skin deep. Not true. Skin is important (the cosmetics industry proves that). But so is what lies under it. In particular, the shape of people’s faces, determined by their bone structure, contributes enormously to how beautiful they are. And, since the ultimate point of beauty is to signal who is a good prospect as a mate, what makes a face beautiful is not only an aesthetic matter but also a biological one. How those bone...

    Scientists claim to have identified the missing link between human speech and monkey chatter. Researchers analysed the distinctive "lip-smacking" sounds made by wild gelada baboons of the Ethopian highlands and found striking similarities to human speech. Their noises are so human-like that Thore Bergman, an assistant professor with the University of Michigan, thought he heard people talking while he was hanging out with the creatures. "I would find myself frequently looking over my shoulder to see who was talking to me, but it was just the geladas," he said. "It was unnerving to have primate vocalizations sound so much...

The startlingly blue people, all descendants of a French immigrant named Martin Fugate and still living near his original settlement on the banks of Troublesome Creek when hematologists studied them in the 1960s, turned out to have a rare blood condition called methemoglobinemia. A recessive gene was pairing with itself to change the molecular composition of their blood, making it brown as opposed to red, which tinted their skin blue. The hematologists'...

    DNA Study Contradicts Human/Chimp Common Ancestry by Brian Thomas, M.S. | Nov. 15, 2011 Evolutionary biologists argue that since human and chimp DNA are nearly identical, both species must have evolved from a common ancestor. However, creation scientists have pointed out that their DNA is, in fact, very dissimilar. The vast majority of each species' DNA sequence is not genes, but instead regulated gene expression. A new report unmistakably confirmed that the regulatory DNA of humans is totally different from that of chimps, revealing no hint of common ancestry. Biologist John F.

Romney, the former Massachusetts governor, also said he would not place restrictions on carbon emissions if elected and did not favor spending heavily on climate solutions.

    Explosive volcanic eruptions might be attention grabbing, but a new review of research finds that their environmental impact pales in comparison to human activities. According to the research, humans put out the same amount of carbon dioxide in three to five days that all of the volcanoes on Earth put out in one year. "Anthropogenic carbon dioxide emissions dwarf global volcanic carbon dioxide emissions," study researcher Terrance Gerlach, of the U.S. Geological Survey, said in a statement. Carbon dioxide, or CO2, is the main greenhouse gas responsible for climate change. Gerlach crunched the carbon dioxide numbers from earlier studies of...

    An improvement in the dating of fossils suggests that the Neanderthals, a heavily muscled, thick-boned human species adapted to living in ice age Europe, perished almost immediately on contact with the modern humans who started to enter Europe from the Near East about 44,000 years ago. Until now bones from several Neanderthal sites have been dated to as young as 29,000 years ago, suggesting there was extensive overlap between the two human species. This raised the question of whether there had been interbreeding between humans and Neanderthals, an issue that is still not resolved. RSS Feed RSS Get Science News...

"The past few decades have been unique in the past 200,000 years in terms of the changes we see in the biology and chemistry recorded in the cores,'' University of Colorado glaciologist Yarrow Axford said. "We see clear evidence for warming in one of the most remote places on Earth at a time when the Arctic should be cooling because of natural processes." Mr Axford is the chief author of the study...

    To the Editor: The Naval Health Research Center serves as the Navy hub for the Department of Defense's Global Emerging Infections Surveillance and Response System (GEIS), in which it monitors influenza-like illness among recruit trainees of all military services, military dependents, and crew members of large Navy ships (population, >1000). The center works in collaboration with the Border Infectious Disease Surveillance Project of the Centers for Disease Control and Prevention (CDC), which monitors populations located on the border between California and Mexico. The first two human cases of novel swine-origin influenza A (H1N1) virus (S-OIV), known as swine flu, in...

    VIENNA (AFP) – They can make fabric resistant to stains, improve the taste of food and help drug research, but nanoparticles could also pose a danger to human health, experts warned Wednesday. Susanne Stark, of the Consumer Information Association, told a seminar in the Austrian city of Salzburg that companies should be forced to indicate on labels whether a product contains the tiny particles. "There are more questions than answers on the effects of nanoparticles" on human health, the chemist said. Cosmetic and food products should indicate whether their products contain nanoparticles by 2012, she said. Nanoparticles, measuring no more...

    When we daydream about the future, we tend to focus on the fabulous belongings we're going to have. Jet packs, flying cars, weapons to kill aliens, cell phones that make today's sleek models look clunky -- you name it, we're going to have it. We don't tend to focus, however, on who we'll be in the future. Most of us probably picture ourselves exactly the same, though maybe thinner, as surely we'll all have robot personal trainers by then. While we see the world's technology evolving to meet our needs, we may not think about how we ourselves might be...

    Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a "soliciting purr" to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a "cry", with a similar frequency to a human baby's. The team said cats have "tapped into" a human bias - producing a sound that humans find very difficult to ignore.
  • Cats Do Control Humans, Study Finds

    If you've ever wondered who's in control, you or your cat, a new study points to the obvious. It's your cat. Household cats exercise this control with a certain type of urgent-sounding, high-pitched meow, according to the findings. This meow is actually a purr mixed with a high-pitched cry. While people usually think of cat purring as a sign of happiness, some cats make this purr-cry sound when they want to be fed. The study showed that humans find these mixed calls annoying and difficult to ignore. "The embedding of a cry within a call that we normally associate with...
  • How Neanderthals met a grisly fate: devoured by humans

    A fossil discovery bears marks of butchering similar to those made when cutting up a deerOne of science's most puzzling mysteries - the disappearance of the Neanderthals - may have been solved. Modern humans ate them, says a leading fossil expert. The controversial suggestion follows publication of a study in the Journal of Anthropological Sciences about a Neanderthal jawbone apparently butchered by modern humans. Now the leader of the research team says he believes the flesh had been eaten by humans, while its teeth may have been used to make a necklace.

    snip It's even conceivable, he said, that our genes eventually will change enough to create an entirely new human species, one no longer able to breed with our own species, Homo sapiens. "Someday in the far distant future, enough genetic changes might have occurred so that future populations could not interbreed with the current one,'' Sussman said in an e-mail message. snip It's also the topic of a new book, "The 10,000 Year Explosion,'' by anthropologists Henry Harpending and Gregory Cochran of the University of Utah, Salt Lake City. "For most of the last century, the received wisdom in the...
