  • Link established between Jupiter moon surface and ocean below
    A study of Jupiter's moon Europa indicates that the icy surface may not be as thick as once believed, possibly offering scientists easier access to the ocean trapped beneath it. Using Hawaii's Keck II Telescope, scientists detected a spectroscopic signal caused by a magnesium-based substance that wouldn't have been possible without contact with the ocean below. "We now have evidence that Europa's ocean is not isolated. ... That means that energy might be going into the ocean, which is important in terms of the possibilities for life there," said Mike Brown, lead author of the study.

  • Scientists confirm existence of ancient crater beneath Iowa
    Using a series of aerial imagery, scientists confirmed the existence of a 470-million-year-old meteorite crater beneath Decorah, Iowa. The Decorah Impact Structure was found during an analysis of core samples between 2008 and 2009, where scientists discovered a unique sample of shale that they believe an ancient seaway deposited at some point after the crater was formed.

  • U.S.-Russian crew will launch to space station in record time
    A new launch plan is expected to send a crew of U.S. and Russian astronauts to the International Space Station in record time -- six hours compared with the typical two days. The crew will perform its final training for the Russian Soyuz capsule launch and will be the first manned flight to test the new travel plan. (3/6) LinkedInFacebookTwitterEmail this Story
  • Domestic dogs may have been around 33,000 years ago, study says
    Dogs may have become domesticated as early as 33,000 years ago, according to findings published in the journal PLoS ONE. The conclusion is based on an analysis of an ancient canine skull found in the Altai Mountains of Siberia that is believed to be more closely related to domesticated dogs than their wild wolf relative. While it's been widely accepted that domesticated dogs were rampant as early as 10,000 years ago, the Altai skull is one of two oldest-known possible domestic dog remains.

  • Study: Ancient wealthy Egyptians weren't immune to disease
    Analysis of skeletal remains excavated from the Qubbet el-Hawa necropolis, near the modern city of Aswan, Egypt, reveals that well-off ancient Egyptians may have been just as likely to contract malnutrition or disease despite their wealth. "Although the cultural level of the age was extraordinary, the anthropological analysis of the human remains reveals the population in general, and the governors -- the highest social class -- lived in conditions in which their health was very precarious, on the edge of survival," said researcher Miquel Botella Lopez.

  • Could salty food be the cause behind autoimmune diseases?
    Diets high in salt may contribute to autoimmune diseases such as multiple sclerosis and inflammatory bowel disease, according to a study published in the journal Nature. The findings, based on studies of cultured cells and rodents, suggest salt promotes the development of an immune cell often identified as the culprit behind various autoimmune diseases. Researchers plan to look at whether there is a link between a high-salt diet and human autoimmune diseases. Now blog (3/6) LinkedInFacebookTwitterEmail this Story
  • Cancer researchers plan massive genome project
    Researchers at the National Cancer Institute are looking to pool their work into a broader project that would catalog a survey of cancer tumors. The idea comes after scientists have begun wrapping up the Cancer Genome Atlas, a project that has cost more than $375 million and involved more than 150 researchers and nearly 10,000 cancer samples. Now, researchers hope to multiply that work to include 10,000 samples of every type of common cancer. Insider blog (3/6) LinkedInFacebookTwitterEmail this Story

  • Young researchers feel funding squeeze
    The average age of first-time NIH research project grant winners is 42 for those with a doctorate degree, 44 for medical and doctorate degree holders and 45 for people with a medical degree. These averages have remained steady since 2000, according to data. Many young researchers are leaving the life-sciences field. Young postdocs may be more likely than established investigators to take risks and explore ideas with significant translational impact, but an inability to obtain funding impedes their research, says Jeremy Herskowitz, who received a fellowship from BrightFocus Foundation for his Alzheimer's disease studies.
