Findings from the study, which has yet to be published or reviewed in detail by other scientists, were presented at a meeting of the American Society of Human Genetics in Baltimore.
  • Ancient Ethiopian man's genome illuminates ancestry of Africans

    Handout photo of the entrance to the Mota cave where the remains containing the ancient genome were found in EthiopiaBy Will Dunham WASHINGTON (Reuters) - DNA extracted from the skull of a man buried 4,500 years ago in an Ethiopian cave is providing new clarity on the ancestry of modern Africans as well as shedding light on an influx of people from the ancient Middle East into the Horn of Africa. Until now, genome sequencing efforts on ancient people have focused on remains from cooler, drier climes that tend to better preserve DNA. The cave, sitting 6,440 feet (1,963 meters) above sea level in southwestern Ethiopia's Gamo highlands, was discovered in 2011, University of Cambridge geneticist Andrea Manica said.

  • Ice Age Mammoth Bones Discovered on Michigan Farm

    Ice Age Mammoth Bones Discovered on Michigan FarmTwo Michigan farmers made an unexpected discovery in a wheat field last week: the ice-age bones of a mammoth that was likely slaughtered by ancient humans. An excavation and analysis of the bones suggest they come from an adult male mammoth that had an unlucky end. "We think that humans were here and may have butchered and stashed the meat [in a pond] so that they could come back later for it," Daniel Fisher, a University of Michigan paleontologist who led the excavation, said in a statement.

  • Killer Show! Murder Weapons and Death Masks Star in New Exhibit

    Killer Show! Murder Weapons and Death Masks Star in New ExhibitA shovel used to bury the body of a murder victim in 1910, an antique-looking gun that fired a shot at Queen Victoria in 1840 (it missed) and death masks from convicted criminals: These are among the strange and grisly artifacts associated with some of the most notorious crimes in recent British history. And they are now on display in the "Crime Museum Uncovered" exhibit that opens today (Oct. 9) at the Museum of London. The exhibit's storied artifacts are on loan from the Crime Museum — a private gallery of objects retained from prisoners and crime scenes, which is located at the Metropolitan Police headquarters at New Scotland Yard in London.

  • Marble Caves and Neolithic Stones Shine in UK Photo Contest

    Marble Caves and Neolithic Stones Shine in UK Photo ContestOn a cold, drizzly afternoon, Brent Bouwsema drove with his wife and two children to photograph some of the oldest stones in the British Isles. Geologists think the Callanish Stones, which are made of an ancient type of rock called Lewisian gneiss, were built in the Neolithic period about 5,000 years ago. Bouwsema took a photo of the moss-covered pillars, and ended up as one of the winners of the "100 Great Geosites" photography contest, The Geological Society of London announced today (Oct. 9).

  • Apollo Photos Redux: The Story Behind the NASA Moon Pics Posted to Flickr

    Apollo Photos Redux: The Story Behind the NASA Moon Pics Posted to FlickrThe addition of tens of thousands of the Apollo astronauts' moon photos to an online repository drew worldwide media interest this week, but lost in many of the headlines were the facts behind the four-decade-old photographs. Numerous news articles declared the photos were "never before seen" and attributed the upload to NASA, neither of which were true. "Contrary to some recent media reports, this Flickr gallery is not a NASA undertaking, but an independent one," said Kipp Teague, the founder of the Project Apollo Archive, in an introduction he wrote for the newly-added gallery.

  • Scientists predict drier Horn of Africa as climate warms

    A woman feeds her drought-stricken cattle with dried corn leaves in MogadishuBy Megan Rowling BARCELONA (Thomson Reuters Foundation) - The Horn of Africa is becoming drier in step with global warming, researchers said on Friday, contradicting some climate models predicting rainier weather patterns in a region that has suffered frequent food crises linked to drought. A new study using a sediment core extracted from the Gulf of Aden found the East African region covering Somalia, Djibouti and Ethiopia has dried at an unusually fast rate over the past century. Lead author Jessica Tierney, an associate professor at the University of Arizona, told the Thomson Reuters Foundation the research team was confident the drying was linked to rising emissions of climate-changing greenhouse gases, and was expected to continue as the region heats up further.

  • Computer science now top major for women at Stanford University

    Stanford University's campus is seen from atop Hoover Tower in Stanford, CaliforniaBy Sarah McBride SAN FRANCISCO (Reuters) - Computer science has for the first time become the most popular major for female students at Stanford University, a hopeful sign for those trying to build up the thin ranks of women in the technology field. Based on preliminary declarations by upper-class students, about 214 women are majoring in computer science, accounting for about 30 percent of majors in that department, the California-based university told Reuters on Friday. If more women majored in technological fields like computer science, advocates say, that could help alleviate the dearth of women in engineering and related professions, where many practitioners draw on computer science backgrounds.

  • Beating parasites wins three scientists Nobel prize for medicine By Simon Johnson and Ben Hirschler STOCKHOLM/LONDON (Reuters) - Three scientists from Japan, China and Ireland whose discoveries led to the development of potent new drugs against parasitic diseases including malaria and elephantiasis won the Nobel Prize for Medicine on Monday. Irish-born William Campbell and Japan's Satoshi Omura won half of the prize for discovering avermectin, a derivative of which has been used to treat hundreds of millions of people with river blindness and lymphatic filariasis, or elephantiasis. China's Tu Youyou was awarded the other half of the prize for discovering artemisinin, a drug that has slashed malaria deaths and has become the mainstay of fighting the mosquito-borne disease.
  • Nobel prize for solving puzzle of ghostly neutrino particles By Simon Johnson and Ben Hirschler STOCKHOLM/LONDON (Reuters) - A Japanese and a Canadian scientist won the 2015 Nobel Prize for Physics on Tuesday for discovering that elusive subatomic particles called neutrinos have mass, opening a new window onto the fundamental nature of the universe. Neutrinos are the second most bountiful particles after photons, which carry light, with trillions of them streaming through our bodies every second, but their true nature has been poorly understood. Takaaki Kajita and Arthur McDonald's breakthrough was the discovery of a phenomenon called neutrino oscillation that has upended scientific thinking and promises to change understanding about the history and future fate of the cosmos.
  • Scientists call for urgent trials to judge flu drugs for pandemics

    Four capules of Tamiflu are pictured on a Tamiflu box in BurbankBy Kate Kelland LONDON, Oct 8 (Reuters) - - Scientists still don't know if two commonly-used flu drugs -- Roche's Tamiflu and GlaxoSmithKline's Relenza -- really work in seasonal or pandemic flu outbreaks and say robust clinical trials are urgently needed to find out. While such medicines are stockpiled by governments around the world and were widely used in the 2009/2010 H1N1 "swine flu" pandemic, no randomised trials were conducted then, so evidence is scant on how effective that approach was. Publishing a report on the use of such antiviral drugs - known as neuraminidase inhibitors - against flu, experts co-led by Wellcome Trust director Jeremy Farrar said this had been a huge wasted opportunity and one that should not happen again.

  • Ruffling the feathers: scientists formulate bird family tree The evolutionary relationships among the world's 10,000 bird species have been tough to decipher. But scientists on Wednesday unveiled the most comprehensive account of the avian family tree ever formulated, detailing how modern bird groups are connected based on genome-wide data from 198 living bird species.    They focused in particular on understanding the group called Neoaves, encompassing more than 90 percent of all birds, the exceptions being large flightless birds like ostriches and a group including ducks and chickens. "It means that all of these aquatic birds may have evolved from a single common ancestor, as opposed to evolving an aquatic ecology multiple times independently," Cornell University ornithologist Jacob Berv said. "So the common ancestor of the woodpecker and the chickadee in your garden was a vicious, hawk-like meat-eater," Prum said.

  • Nobel Prize in Physics Honors Flavor-Changing Neutrino Discoveries

    Nobel Prize in Physics Honors Flavor-Changing Neutrino DiscoveriesTakaaki Kajita and Arthur B. McDonald will share this year's Nobel Prize in physics for helping to reveal that subatomic particles called neutrinos can change from one type to another — a finding that meant these exotic particles have a teensy bit of mass. Neutrinos are the second-most abundant particles in the cosmos, constantly bombarding Earth. In their separate experiments, Kajita and McDonald each showed that neutrinos change between certain flavors — a process called neutrino oscillation.

  • Heating up hair science "I was always wondering how we can think about this from a mechanical engineering perspective," she added.   So Reid stepped out of the salon and into her laboratory. There she teamed up with fellow researchers Amy Marconnet and Jaesik Hahn to answer this question - what is the perfect amount of heat to apply when straightening hair without causing permanent damage? Reid said too much heat applied over a long period of time could destroy the natural curve in hair leaving it permanently damaged.  "We are wanting to see the point at which hair becomes permanently straightened, it's otherwise called heat damage.

  • Scientists find genes that protect African children from malaria

    A displaced girl is tested for malaria in Tomping camp, where some 17,000 displaced people are being sheltered by the UN, in JubaBy Kate Kelland LONDON (Reuters) - Scientists have identified specific genetic variations that protect some African children from developing severe malaria and say their discovery will boost the fight against a disease that kills around half a million children a year. In the largest study of its kind, the researchers said identifying the variations in DNA at a specific location, or locus, on the genome helps explain why some children develop severe malaria and others don't in communities where people are constantly exposed to the mosquito-borne disease. In some cases, they said, having a specific genetic variation almost halves a child's risk of developing a life-threatening case of the disease.
