  1. How do blind cavefish find their way? The answer could be in their bones.

    05.24 / 20:54 eurekalert.org Eurekalert.org - Biology
    (University of Cincinnati) Blind cavefish typically have skulls that bend slightly to the left. A study by UC suggests this orientation might help them find food as they navigate in a perpetual counter-clockwise direction around a…
  2. South Sudan wildlife surviving civil war, but poaching and trafficking threats increase

    05.24 / 20:54 eurekalert.org Eurekalert.org - Biology
    (Wildlife Conservation Society) The first aerial assessment of the impact of South Sudan's current civil war on the country's wildlife and other natural resources shows that significant wildlife populations have so far survived, but poaching and commercial wildlife trafficking are increasing, as well as illegal mining, timber harvesting and charcoal production, the Wildlife Conservation Society (WCS) said in a report issued…
  3. Grant to fund research of microplastics in Delaware Bay

    05.24 / 20:54 eurekalert.org Eurekalert.org - Biology
    (University of Delaware) University of Delaware researchers have received funding to study the distribution and concentration of microplastics in the Delaware Bay. This small debris can cause problems in the aquatic food chain. The UD team is hoping their findings can help government regulators shape new policy to protect the…
  4. Are wolverines in the Arctic in the climate change crosshairs?

    05.24 / 16:56 eurekalert.org Eurekalert.org - Biology
    (Wildlife Conservation Society) Will reductions in Arctic snow cover make tundra-dwelling wolverines more vulnerable to climate change than previously thought? That's a question scientists hope an innovative method described in a new study co-authored by WCS (Wildlife Conservation Society) will help…
  5. Fossil beetles suggest that LA climate has been relatively stable for 50,000 years

    (American Museum of Natural History) Research based on more than 180 fossil insects preserved in the La Brea Tar Pits of Los Angeles indicate that the climate in what is now southern California has been relatively stable over the past 50,000…
  6. LA lawns lose lots of water: 70B gallons a year

    05.24 / 14:57 eurekalert.org Eurekalert.org - Biology
    (University of Utah) In summer 2010, Los Angeles was losing about 100 gallons of water per person per day to the atmosphere through the evaporation and plant uptake of lawns and trees. Lawns accounted for 70 percent of the water loss, while trees accounted for 30 percent, according to a University of Utah study published in Water Resources…
  7. Disaster risk management: Science helps save lives

    05.24 / 14:57 eurekalert.org Eurekalert.org - Biology
    (European Commission Joint Research Centre) Natural and man-made disasters threaten millions of people every year and cause billions of property damage. How much do we know about them? And how can we use that knowledge to save lives and money? A recent report, compiled by the European Commission's Science and Knowledge Service (JRC), seeks to answer these and other questions and to help prepare for the time when disaster…
  8. LSTM and partners develop molecule that may lead to first synthetic one-dose antimalarial

    05.24 / 14:57 eurekalert.org Eurekalert.org - Biology
    (Liverpool School of Tropical Medicine) Researchers at LSTM, working in partnership with the University of Liverpool and other colleagues, have developed a molecule which has the potential to become the first fully synthetic, one-dose treatment for…
  9. Dartmouth-led study finds heavier precipitation in the northeast began in 1996

    05.24 / 04:19 eurekalert.org Eurekalert.org - Biology
    (Dartmouth College) Over the past century, the Northeast has experienced an increase in the number of storms with extreme precipitation. A Dartmouth-led study finds that the increase in extreme Northeast storms occurred as an abrupt shift in 1996, particularly in the spring and fall, rather than as a steady change over several decades. The findings were published in an early online release of the American Meteorological Society's 'Journal of…
  10. A fresh look inside the protein nano-machines

    05.24 / 04:19 eurekalert.org Eurekalert.org - Biology
    (Université de Genève) Proteins perform vital functions, they digest food and fight infections. They are in fact nano-machines, each one of them designed to perform a specific task. But how did they evolve to match those needs, how did the genes encode the structure and function of proteins? Researchers from the University of Geneva, Switzerland, the Institute for Basic Science, Korea, and the Rockefeller University, United States, have conducted a study that tackles this yet…
  11. Lizards may be overwhelmed by fire ants and social stress combined

    05.23 / 22:20 eurekalert.org Eurekalert.org - Biology
    (Penn State) Lizards living in fire-ant-invaded areas are stressed. However, a team of biologists found that the lizards did not exhibit this stress as expected after extended fire ant exposure in socially stressful environments, leading to questions about stress…
  12. Stingless bees have specialized guards to defend their colonies, study reveals

    05.23 / 20:25 eurekalert.org Eurekalert.org - Biology
    (Fundação de Amparo à Pesquisa do Estado de São Paulo) Several species of stingless bees have specialized guards or soldiers to defend their colonies from attacks by natural enemies. The differentiation of these guardian bees evolved in the last 25 million years and coincided with the appearance of parasitic 'robber' bees, which represent a major threat to many stingless bee species. These discoveries were made by a group of researchers in Brazil in collaboration with…

  16. Pope's encyclical boosted his credibility on climate change, especially among liberals

    05.23 / 16:26 eurekalert.org Eurekalert.org - Biology
    (Annenberg Public Policy Center of the University of Pennsylvania) The Pope's 2015 encyclical on climate change did not directly influence people's beliefs about the seriousness of climate change or its effect on the poor, a study in Cognition has found. The papal message did, however, indirectly influence people's beliefs about climate change by raising the Pope's credibility on that issue, most strongly among…
  17. Oyster farming to benefit from new genetic screening tool

    05.23 / 16:26 eurekalert.org Eurekalert.org - Biology
    (University of Edinburgh) Oyster farmers are set to benefit from a new genetic tool that will help to prevent disease outbreaks and improve yields. The technology -- developed by scientists at the University of Edinburgh's Roslin Institute -- will enable hatcheries to rapidly assess the genetic make-up of their oysters, so they can select animals with desirable characteristics from which to…
  18. Cowbird moms choosy when selecting foster parents for their young

  19. Immunotherapy target suppresses pain to mask cancer

    05.23 / 16:26 eurekalert.org Eurekalert.org - Biology
    (Duke University) Duke University researchers found that a molecule called PD-L1, which is blocked by the immunotherapy drug nivolumab, acts not only on immune cells but also on the nerve cells that signal pain. That insight could lead to a simple test that measures subtle differences in pain sensitivity to gauge whether or not a cancer patient is responding to immunotherapy. This study also identifies PD-L1 as a previously unrecognized neuromodulator and pain…
