  • Study: Modern desert camel linked to Arctic ancestors
    Scientists have discovered a link between an ancient camel excavated in Canada's High Arctic tundra and the modern creatures from Africa and Asia. The mummified camel bones came from an area that 3.5 million years ago resembled a northern "boreal-type" forest, said the lead author of the study, which was published in the journal Nature Communications.

  • Study: Female marsupials prefer use of their left paws
    Some female marsupial species are more likely to prefer their left paw for tasks such as eating and building nests than the males, according to a study. In contrast, male humans are more likely to be left-handed than their female counterparts. "We showed for the first time that sex-dependent handedness is reversed in marsupials if compared to other mammals," said researcher Yegor Malashichev. "So they demonstrate an alternative way of developing handedness." Researchers plan to further study handedness in different types of marsupials and wild bats.

  • Mummy head shows advanced medical practice during Dark Ages
    Analysis of a preserved mummy head reveals a surprising amount of accuracy and skill in medical science during Europe's Dark Ages, according to a study. The specimen, which dates between 1200 and 1280 A.D., consists of a head and part of shoulders with the brain removed. "It's state-of-the-art. I suppose that the preparator did not do this just one time, but several times, to be so good at this," said researcher Philippe Charlier.

  • Crystal found in shipwreck confirmed to be calcite
    A small crystal stone discovered in a 16th-century British shipwreck off the island of Alderney has been confirmed to be made of calcite, according to a study published in the Proceedings of the Royal Society A. The confirmation supports an earlier theory that Vikings and other sailors used "sunstones" as a means to navigate waters on cloudy days.

  • Scientists: Sun could reach second peak of activity this year
    Some scientists are predicting that the sun may be getting ready for a second peak in its 11-year activity cycle this year, possibly lasting into next year. The sun is in a calm after a particularly active 2011. The last time it had a double-peaked activity cycle was in 1989 and 2001. If a second peak does occur, scientists point to activity in the sun's southern hemisphere as the main cause. Space.com (3/5) LinkedInFacebookTwitterEmail this Story
  • Researchers use algae gene to boost oil content in plant leaves
    Scientists at Michigan State University used a gene from green algae to boost the oil content in the leaves of the Arabidopsis thaliana plant, a breakthrough that could have implications for bioenergy production, according to a report in the journal The Plant Cell. "If oil can be extracted from leaves, stems and seeds, the potential energy capacity of plants may double," the lead researcher said. DomesticFuel.com (3/5) LinkedInFacebookTwitterEmail this Story
  • Researchers study use of cell signal in delaying stem cell aging
    Researchers at Georgia Regents University are assessing the potential use of a cell signal called stromal derived factor-1 in improving stem cell survival and staving off cell aging. Researchers modified cells to generate more than the normal levels of SDF-1 and found that this increased cell survival after transplant. The approach could potentially treat damaged bones and osteoporosis. The researchers plan to test the approach in older and younger orthopedic patients. The Augusta Chronicle (Ga.)

  • Scientist hopes $5.25M project leads to more transparent research
    A group of psychologists, in collaboration with the journal Perspectives on Psychological Science, is hoping to launch an initiative that will make their field's research more transparent. The project, which has been pledged $5.25 million from private donators, will solicit work from researchers willing to work in the open and allow their work to be duplicated. In a Q-and-A, the project's lead psychologist, Brian Nosek, talks about the project and his hopes for future research.
