  • Scientists solve mystery of polar bear Knut's death

    Journalists watch the full-sized polar bear Knut model covered with the original fur during the presentation to the media at the natural history museum in BerlinKnut, the star polar bear who was hand-reared at Berlin zoo after his mother rejected him, had a type of auto-immune inflation of the brain that is found in humans, scientists said on Thursday. Knut, who was just four when he drowned at the zoo in 2011, was reared by his keeper Thomas Doerflein. Knut had an epileptic fit and drowned in a pool in his enclosure.

  • German scientists find rare dinosaur tracks By Josie Le Blond BERLIN (Reuters) - German scientists have found an unusually long trail of footprints from a 30-tonne dinosaur in an abandoned quarry in Lower Saxony, a discovery they think could be around 145 million years old. "It's very unusual how long the trail is and what great condition it's in," excavation leader Benjamin Englich told Reuters at the site, referring to 90 uninterrupted footprints stretching over 50 meters. Englich said the elephant-like tracks were stomped into the ground sometime between 135 and 145 million years ago by a sauropod - a class of heavy dinosaurs with long necks and tails.
  • Massive Aztec human skull rack found in Mexico City

    Matos Moctezuma, an archaeologist from Mexico's National Institute of Anthropology and History points to a drawing of the Templo Mayor Aztec complex, during a news conference at the Anthropology Museum in Mexico CityArcheologists have discovered a massive ceremonial skull rack from the heyday of the Aztec empire in the heart of Mexico City, a find that could shed new light on how its rulers projected power by human sacrifice, the team said on Thursday. The skull rack, known as a tzompantli in the Nahuatl language of the Aztecs, was used to display the bleached white craniums of sacrificed warriors from rival kingdoms, likely killed by priests atop towering temples that once stood nearby. Dug up behind the capital's colonial-era cathedral, the as yet partially uncovered skull rack was likely built between 1485 and 1502 and may have been about 112 feet (34 meters) long and 12 meters (40 foot) wide, lead archeologist Raul Barrera said.

  • Elusive Sea Creature with Hairy, Slimy Shell Spotted After 31 Years

    Elusive Sea Creature with Hairy, Slimy Shell Spotted After 31 YearsThe Allonautilus scrobiculatus, a species of mollusk in the same family as the nautilus, was spotted off the coast of Papua New Guinea in the South Pacific in early August, the scientists said. The Allonautilus' shell has been known to science since the 1700s. The Allonautilus is so rare likely because it is completely reliant on scavenging to survive, Ward said.

  • Human Eye's Blind Spot Can Shrink with Training The blind spot of the human eye can be shrunk with certain eye-training exercises, thus improving a person's vision slightly, a small new study suggests. In the study of 10 people, researchers found that the blind spot — the tiny region of a person's visual field that matches up with the area in the eye that has no receptors for light, and hence cannot detect any image — can shrink 10 percent, with special training. That amount of change "is quite an improvement, but people wouldn't notice, as we are typically unaware of our blind spots," said study author Paul Miller, of the University of Queensland in Australia.
  • Sexual Harassment in the Animal Kingdom? How Female Guppies Escape

    Sexual Harassment in the Animal Kingdom? How Female Guppies EscapeAnimal-behavior scientists discovered that female fish who were most bothered by this type of sexual harassment started to swim in a different, more efficient way. Researchers from the University of Glasgow and the University of Exeter, both in the United Kingdom, tested the effects of this harassment on Poecilia reticulata guppies. "In the wild, especially during the dry season, [guppies] can be trapped together in small pools for months," said study lead author Shaun Killen, a biologist at the University of Glasgow.

  • New guidelines for cancer doctors aim to make sense of gene tests

    Freitas, a 3-year-old cancer patient, is carried by his parents before an injection in a hospital in BarretosBy Julie Steenhuysen CHICAGO (Reuters) - The American Society of Clinical Oncology (ASCO) has issued guidelines on how cancer doctors should approach the use of new genetic tests that screen for multiple cancer genes at the same time, including counseling patients about genes whose contribution to cancer is still poorly understood. The guidelines aim to educate doctors about the risks and benefits of new genetic tests, argue for regulation to assure quality and call for more equitable reimbursement of the cost of the tests from private and public insurers. The falling price of genome sequencing has made it possible for cancer doctors to cheaply test for a wide variety of mutated genes that could guide treatment or predict a person's risk for cancer.

  • FDA wants food companies to hand over their pathogens

    Handout image of electron micrograph of a Listeria bacterium in tissueBy Julie Steenhuysen CHICAGO (Reuters) - Investigations into foodborne illness are being radically transformed by whole genome sequencing, which federal officials say is enabling them to identify the source of an outbreak far more quickly and prevent additional cases. Previously, samples from sick patients were sent to state and federal labs, where disease detectives ran tests to see if the infections were caused by the same bug. When enough matches emerged, typically a dozen or so, epidemiologists interviewed sick people, looking for a common food that was causing the outbreak.

  • Amazing 'Red Lightning' Photographed from Space

  • Why Does Comet 67P Sing? Scientists Think They Know

    Why Does Comet 67P Sing? Scientists Think They KnowThe sound waves picked up by Rosetta are moving through the comet's magnetic field. In space, no one can hear you scream — that's because on Earth, sound waves move through the air, and there is no atmosphere in space. In empty space, there is no atmosphere, so the sound waves don't have a material to travel through.

  • Science will prevail in doping firestorm - WADA chief

    Sir Craig Reedie, president of the World Anti-Doping Agency, attends a meeting at Jamaica's Olympic Association in KingstonBy Nick Mulvenney BEIJING (Reuters) - Science will ultimately put out the doping firestorm that has engulfed athletics in the run-up to the world championships, Craig Reedie, head of the World Anti-Doping Agency (WADA), said on Friday. The governing body of athletics, the IAAF, has been in crisis since data from thousands of blood samples was leaked to two media organisations this month. Three weeks of further leaks and allegations that the IAAF has been soft on dopers have overshadowed the run-up to its biennial showpiece, which opens in Beijing with the men's marathon on Saturday.

Wikipedia relies on the wisdom of the crowds, allowing anyone to create or edit any Wiki page while others go in and tweak, update or delete revisions.
  • Wormhole Created in Lab Makes Invisible Magnetic Field

    Wormhole Created in Lab Makes Invisible Magnetic FieldRipped from the pages of a sci-fi novel, physicists have crafted a wormhole that tunnels a magnetic field through space. "This device can transmit the magnetic field from one point in space to another point, through a path that is magnetically invisible," said study co-author Jordi Prat-Camps, a doctoral candidate in physics at the Autonomous University of Barcelona in Spain. The idea of a wormhole comes from Albert Einstein's theories.

  • July was hottest month recorded worldwide: U.S. scientists

    A man washes his face to cool off during a warm summer day in BaghdadJuly was the warmest month ever on record worldwide and 2015 has been so far the hottest year, the U.S. National Oceanic and Atmospheric Administration said on Thursday, just over three months to go before world leaders seek to reach a climate agreement in Paris. In its monthly global climate report released online on Thursday, NOAA said many countries and the world's oceans experienced heatwaves, with the Earth's oceans temperature also hitting record highs last month. This July was the all-time highest monthly temperature in the records that date back to 1880, at 61.86 degrees Fahrenheit (16.61 degree Celsius), according to NOAA.

  • 'Base Jumping' Spider Soars from Rainforest Treetops

    'Base Jumping' Spider Soars from Rainforest TreetopsIn addition to these arachnids, lots of small insects (including many species of ants and bristletails) are known to engage in similar behavior — leaping from the tippy tops of trees with total confidence, even though they don't have wings to help them along, said Stephen Yanoviak, an associate professor of biology at the University of Louisville and lead author of the new study. Selenops, often called "flatties" because of their exceedingly thin bodies, blend in well in tropical forest environments, the researchers said. Then, they took the spiders high up into the forest canopy and turned the cups upside down.

  • Scientists call for new review of herbicide, cite 'flawed' U.S. regulations U.S. regulators have relied on flawed and outdated research to allow expanded use of an herbicide linked to cancer, and new assessments should be urgently conducted, according to a column published in the New England Journal of Medicine on Wednesday. There are two key factors that necessitate regulatory action to protect human health, according to the column: a sharp increase in herbicide applied to widely planted genetically modified (GMO) crops used in food, and a recent World Health Organization (WHO) determination that the most commonly used herbicide, known as glyphosate, is probably a human carcinogen. The opinion piece was written by Dr. Philip Landrigan, a Harvard-educated pediatrician and epidemiologist who is Dean for Global Health at the Mount Sinai Medical Center in New York, and Chuck Benbrook, an adjunct professor at Washington State University's crops and soil science department.

  • Scientists researching brain disorders create super-clever mice By Kate Kelland LONDON (Reuters) - Scientists have genetically modified mice to be super-intelligent and found they are also less anxious, a discovery that may help the search for treatments for disorders such as Alzheimer's, schizophrenia and post traumatic stress disorder (PTSD). Researchers from Britain and Canada found that altering a single gene to block the phosphodiesterase-4B (PDE4B) enzyme, which is found in many organs including the brain, made mice cleverer and at the same time less fearful. "Our work using mice has identified phosphodiesterase-4B as a promising target for potential new treatments," said Steve Clapcote, a lecturer in pharmacology at Britain's Leeds University, who led the study.
  • Scientists use bioengineered yeast instead of poppies to make opioids

    Handout photo of Stanford University team members Trenchard, Smolke, Galanie and ThodeyBy Will Dunham WASHINGTON (Reuters) - Scientists have invented a speedy method to make potent painkilling opioids using bioengineered baker's yeast instead of poppies, but need to fine-tune the process to make it commercially viable, according to a study published on Thursday. The new method, if it can be made more efficient, could significantly change the multibillion-dollar pain medication manufacturing business, but raises concerns about aggravating the growing problem of opioid abuse. The scientists said they altered the yeast's genetic make-up in a way that coaxed the cells to convert sugar into two opioids - hydrocodone and thebaine - in three to five days.

  • Tennis Ball-Size Octopuses Suction Each Other During Sex

    Tennis Ball-Size Octopuses Suction Each Other During SexThe larger Pacific striped octopus, or LPSO for short, engages in a variety of odd behaviors — from startling prey into its outstretched arms with a sneaky tapping motion to suctioning onto its partner during mating. Though scientists first observed the species in the 1970s, LPSOs have remained relatively unstudied until recently, said Roy Caldwell, a professor of integrative biology at the University of California, Berkeley, whose study outlining the LPSO's odd tendencies was published today (Aug. 12) in the journal PLOS One.
