  • Researchers examine how Tyrannosaurus ate Triceratops
    An analysis of bite-scarred Triceratops fossils from the Hell Creek Formation in Montana helped researchers develop a theory on how Tyrannosaurus fed. Researchers discovered the characteristic tooth marks of Tyrannosaurus on 18 Triceratops specimens, with marks mostly seen on the skulls. Researchers believe that Tyrannosaurus tried to pull the head off Triceratops to feed on neck muscles, after finding that the specimens had extensive puncture and pull marks on their neck frills with no signs of healing, meaning that the bites were inflicted when the animals were dead.

  • Ornithomimus may have used feathers for protection and courtship
    The dinosaur species Ornithomimus may have evolved feathers for courtship or protecting its young, according to a study in the journal Science. Researchers discovered that the arms of a complete adult fossil had vaned or stiff feathers such as those in flying birds, while the arms of the young had filamentary feathers. They suggested that the feathers might not be used for flying; instead they were used for shielding juveniles or for sexual displays, since the species came from an evolutionary branch of birds long before flight originated.

  • Statue carved from meteorite might be a hoax, experts say
    Many experts doubt the claim that a statue of Buddha, called the Iron Man and believed to be made from a piece of meteorite, was created 1,000 years ago and taken by the Nazis during an expedition to Tibet in the late 1930s. An analysis of the statue done by Achim Bayer of Dongguk University in Seoul, South Korea, has pointed out several indications that it is a fake and was possibly produced between 1910 and 1970 in Europe. The statue's pants, "European shoes" and full beard attest to its more recent origin, Bayer wrote. Deities in Mongolian and Tibetan art generally have wispy, thin beards.

  • Calif. "meteorite" is just an Earth rock, scientist says
    A microscopic analysis revealed that a rock thought to be a meteorite from a fireball seen over Northern California on Oct. 17, is just a normal Earth rock. Peter Jenniskens, head of the Cameras for Allsky Meteor Surveillance, thought the stone, found in a backyard in Novato, Calif., was a meteorite based on its density and magnetic response. "I sincerely thought it was, based on what appeared to me was remnant fusion crust," Jenniskens said. "On closer inspection, that crust was a product of weathering of a natural rock, not from the heat of entry." Scientists are still hoping to find a meteorite from the fall.

  • Spacecraft witnesses massive release of ethylene gas on Saturn
    NASA's Cassini spacecraft witnessed a 150 degree Fahrenheit temperature increase and a massive release of ethylene gas by Saturn as the probe collects data on a 2-year storm that surrounded the planet. The temperature during the gas release reached up to minus 64 degrees Fahrenheit, scientists said. "To get a temperature change of the same scale on Earth, you'd be going from the depths of winter in Fairbanks, Alaska, to the height of summer in the Mojave Desert," said the study's lead author Brigette Hesman of the University of Maryland.

  • Scientists seek better system for forecasting aftershocks
    A series of damaging earthquakes this year is prompting U.S. scientists to call for speeding up work developing an improved and reliable system that can be used for forecasting possible aftershocks in the days after a powerful earthquake. "No other recorded earthquake has triggered as many large aftershocks around the world. We believe this was because it was the largest 'strike-slip' earthquake (where the two sides of a fault slip horizontally past each other) ever recorded, involving horizontal motions," said Roland Burgmann, a professor in the Department of Earth and Planetary Science at the University of California, Berkeley.

  • Study looks at fecal microbial flora in pediatric Crohn's disease
    Australian researchers assessed fecal samples from 19 children with Crohn's disease and 21 controls, and found significantly reduced Firmicutes bacteria levels in those diagnosed with the condition. They also noted a greater proportion of Bacteroidetes and Proteobacteria in the Crohn's group than in the control group. The findings appear in the Journal of Clinical Microbiology.

  • Prenatal intake of probiotics may lower babies' risk of eczema
    Babies born to mothers who took probiotics during the last two months of pregnancy and first two months of breast-feeding had a lower risk of developing eczema than the placebo group, according to a Finnish study. The findings, based on 241 pregnant women and their babies, appear in the Journal of Allergy and Clinical Immunology. Reuters (10/25) LinkedInFacebookTwitterEmail this Story

  • DARPA announces selection of 7 robot designs for robotics challenge
    The Defense Advanced Research Projects Agency announced that it chose seven robot designs for its $2 million DARPA Robotics Challenge, which aims to develop robots capable of working with humans during a disaster. The agency is interested in robots with potential to perform many tasks that humans do, including climbing a ladder or opening a door using the handle.

  • Cellular Dynamics lands up to $7M stem cell contract from NIH
    The National Institutes of Health awarded Cellular Dynamics International a three-year contract worth as much as $7 million to provide human induced pluripotent stem cell lines and permanently differentiated cells for use in preclinical testing. "This contract enables NIH researchers to easily access our human iPS cell-derived cells and accelerate the pace of their research," CDI Chief Operating Officer Chris Parker said.
