Fat mice have metabolisms that help keep them fat, new research shows. (AP Photo/Robert F. Bukaty)

  Thelivers of obese mice respond to sugar many times slower than those in healthy mice because they must rely on a less-efficient form of metabolism, according to a study published in Science Signaling, demonstrating fundamental differences in how their Read more…


Could fish genes lead to humans regrowing limbs? (Pixabay/Darwin Laganzon)

  Researchers from Harvard University and Boston Children’s Hospital have discovered that certain gene mutations in zebrafish lead to the formation of limb-like structures in the fish’s pectoral fins, a major development that suggests the same genes likely play a Read more…


Male sea turtles are scarce as hatching-ground sand temperatures rise. (Ga. Dept. of Natural Resources via AP)

  It’s possible that endangered sea turtle hatchlings born on important coastlines of the Red Sea are now mostly female, according to new research, and climate change is poised to push scorching nesting-site temperatures even higher. Sand temperatures at nesting Read more…


Lakes will get and stay hotter for longer, leading to ecosystem troubles. (AP Photo/Dar Yasin)

  As the climate changes, lakes are on track to experience lengthier and more severe periods of extreme warm surface temperatures by the end of the century, novel research published Wednesday shows, with some even projected to reach a “permanent Read more…


Gut health is linked to the rest of the body. (Pixabay/Cassiopeia Arts)

  For the first time, bacteria in the gut have been shown by researchers to play a direct role in the human immune system by impacting levels of white blood cells, potentially opening doors for improvements in immunotherapy. The findings, Read more…


Plants may stop growing not because of weakness, but because their own chemical signals tell them to. (Unsplash/Silvestri Matteo)

  Roots stop growing in densely packed hard soils not because they’re physically constrained but because of a chemical signal from the plant hormone ethylene, new research suggests, so turning the signal off might improve stunted crop yields. The study, Read more…
