Imagine watching your favorite nature documentary. The predator lunges rapidly from its hiding place, jaws wide open, and the prey … suddenly goes limp. It looks dead. https://phys.org/news/2025-06-sharks-upside-good.html Plants & Animals Tue, 24 Jun 2025 13:10:25 EDT news669989413 A new study shows that, contrary to previous assumptions, female common frogs can reject males and have developed a variety of mate avoidance behaviors to do so. The research was led by Carolin Dittrich and Mark-Oliver Rödel from the Museum für Naturkunde in Berlin and was published in the open access journal Royal Society Open Science. https://phys.org/news/2023-10-female-common-frogs-fake-death.html Plants & Animals Wed, 11 Oct 2023 12:06:42 EDT news616244797 Climate change may lead to a reduction in international mobility for populations with the lowest income levels in sub-Saharan Africa, North Africa and the former Soviet Union by up to 10% by 2100. This could rise to up to 35% under more pessimistic scenarios, according to a modeling study published in Nature Climate Change. https://phys.org/news/2022-07-climate-areas-dangerous-harder.html Environment Fri, 08 Jul 2022 09:01:03 EDT news576489662 Across many animal species there is great evolutionary pressure on males, who often engage in combat for the rights to copulation. This phenomenon, called sexual selection, often ends up favoring males with larger weapons, such as horns or pincers. Interestingly, scientists have noted that males endowed with smaller weapons adopt alternative reproductive tactics in some species. For example, instead of fighting other more powerful males, they may try to sneak around or disperse in search of a lonely female. https://phys.org/news/2021-01-size-male-weapons-affects-anti-predator.html Plants & Animals Thu, 28 Jan 2021 10:26:55 EST news531051998 For many of us, the COVID-19 pandemic has led to drastic changes in how we move about in our daily lives. Adhering to social distancing rules, millions of people are now working and socializing from home—only venturing out for essential trips. This shift marks a stark contrast to a mere few months ago when many were able to freely move about, not only of necessity but for desire and fun. https://phys.org/news/2020-04-pradigms-mobility-immobility-upended-pandemic.html Social Sciences Tue, 28 Apr 2020 08:40:01 EDT news507280967 It happens to everyone: You stay up late one night to finish an assignment, and the next day, you're exhausted. Humans aren't unique in that; all animals need sleep, and if they don't get it, they must make it up. https://phys.org/news/2013-03-molecular-key-exhaustion-deprivation.html Cell & Microbiology Thu, 07 Mar 2013 12:59:54 EST news281883588 Physicians use inhalation anesthetics in a way that is incredibly safe for patients, but very little is known about the intricacies of how these drugs actually work in children and adults. Now, researchers have uncovered what cells respond to anesthesia in an organism known as the C. elegans, according to a new study from the Seattle Children's Research Institute. C. elegans is a transparent roundworm used often in research. The study, "Optical reversal of halothane-induced immobility in C. elegans," is published in the December 20, 2011 issue of Current Biology. https://phys.org/news/2011-12-uncovers-clues-anesthetics.html Cell & Microbiology Thu, 22 Dec 2011 09:28:02 EST news243768435
