  • Deep impact: Deep-sea wildlife more vulnerable to extinction than first thought
    on March 22, 2018 at 7:03 pm

    The existence of the unusual yeti crabs (Kiwaidae) -- a family of crab-like animals whose hairy claws and bodies are reminiscent of the abominable snowman -- since 2005, but already their future survival could be at risk. New Oxford University research suggests that past environmental changes may have profoundly impacted the geographic range and species diversity of this family. The findings indicate that such animals may be more vulnerable to the effects of human resource exploitation and climate change than initially thought. […]

  • The mouse brain can prioritize hunger by suppressing pain when survival is at stake
    on March 22, 2018 at 6:10 pm

    Different behaviors are often studied in isolation, leaving unanswered questions about how the brain processes needs and prioritizes behaviors to ensure survival. Now, researchers have shown that pain and hunger interact in complex ways in mice: extreme hunger suppresses less-urgent inflammatory pain, but leaves them able to feel and react to more life-and-death kinds of pain. The study pinpoints a highly specific neural circuit that creates this analgesic effect. […]

  • Physical disability boosts parenting effort, beetles study shows
    on March 22, 2018 at 4:50 pm

    Animals that carry a physical impediment can work harder to rear their young as a result, an insect study has shown. They may behave this way in case they are not able to reproduce again, scientists suggest. […]

  • Despite high blood sugar, cavefish live long, healthy lives
    on March 21, 2018 at 6:14 pm

    Mexican cavefish have insulin resistance, a hallmark of many human metabolic disorders and a precursor to type 2 diabetes that can lead to an overworked pancreas, excess fat storage and chronically elevated blood sugar. Despite dysregulated blood sugar, the fish don't suffer the same health consequences people do. Study offers a fresh opportunity to understand how animals thrive with traits that sicken humans and could point the way to new interventions for disease. […]

  • Hunting squid slowed by rising carbon levels
    on March 21, 2018 at 1:47 pm

    Scientists have found that high carbon dioxide levels cause squid to bungle attacks on their prey. Investigators said that the oceans absorb more than one-quarter of all the excess carbon dioxide (CO2) released into the atmosphere by humans and this uptake of additional CO2 causes seawater to become more acidic. […]

  • Elephant and cow manure for making paper sustainably
    on March 21, 2018 at 1:09 pm

    It's likely not the first thing you think of when you see elephant or cow dung, but this material turns out to be an excellent source of cellulose for paper manufacturing. Upcycling manure into paper products could be a cheap and environmentally sound method to get rid of this pervasive agricultural waste. […]

  • The curse of zombie fossils
    on March 21, 2018 at 1:08 pm
