You might never spot them if not for the jumping. On the coast of Guam, Pacific leaping blennies blend in perfectly with the rocks they live on, their limbless bodies maintaining a sleek profile. But the creatures give themselves away when they coil their tails to one side and shoot like a spring from rock to rock. These unsettling animals are fish that live on land. How they pull it off could give us hints about the evolution of our first earthbound ancestors.Terry Ord, an evolutionary ecologis........ Read more »

This video and picture were made in 2011, but are currently reliving their fame on social media. The material is cute, of course, and interesting. It shows how encaptured chimps can be taught to care for their predator’s cubs. A chimp’s natural environment can also make him do just the opposite. In 1986 researchers described how a group of wild chimpanzees deliberately managed to drag a leopard’s cub away from its mother and then kill it.... Read more »

Studying the ways people talk to themselves in their own minds is incredibly tricky because as soon as you ask them about it, you're likely interfering with the process you want to investigate. As William James said, some forms of introspective analysis are like "… trying to turn up the gas quickly enough to see how the darkness looks."For many years Russell Hurlbert and his colleagues have used a technique that they believe offers the best way to study what they call "pristine" inner speaking........

Researchers have reported that vitamin D supplementation for 3 years or more significantly decreases all-cause mortality in female patients with vitamin D insufficiency.

Vitamin D is a fat-soluble vitamin that occurs in fish-liver oils and is often added to milk. They are essential for the formation of bones and teeth. Lack of vitamin D causes rickets. Vitamin D deficiency below baseline levels ........ Read more »

As winter sets in, small, resident insectivorous birds including Long-tailed tits, Great Tits and Blue Tits, Coal Tits, Goldcrests and Treecreepers join in loose, vocal mixed-species flocks that travel and forage together. Why do they eschew from following the saying 'birds of a feather flock together'? Well, first, their small bodies lose heat easily and the days are short, so they need to obtain as much food as possible. On the other hand, the leafless trees makes them more exposed to predatio........ Read more »

(*For certain possibly nonstandard uses of the word "unpublished")This is an odd little study. Instead of looking at registered trials and following them through to publication, this study starts with a random sample of phase 3 and 4 drug trials that already had results posted on ClinicalTrials.gov - so in one, very obvious sense, none of the trials in this study went unpublished. But here the authors are concerned with publication in medical journals, and they........ Read more »

Theories about the domestication of dogs often say they have evolved to pay more attention to humans than their wolf forebears. But the experimental evidence tends to only look at dogs. A new study by Friederike Range (University of Veterinary Medicine Vienna) and Szófia Virányi (Wolf Science Centre) compares the abilities of dogs and hand-reared wolves to utilize observations of human or dog behaviour to find food.Photo: Holly Kuchera / ShutterstockEleven wolves and fourteen do........

Fats are bothersome to most us, but essential to life. Lipodystrophies are dysfunctions in fat storage, including lipoatrophies where fat is lost from a specific part of the body. In HIV, there is lipoatrophy in the face, but deposition of fat around the visceral organs. A new study shows tracked different markers in each location and found that mitochondrial changes were the same in visceral adipose tissue (VAT) and subdermal adipose tissue (SAT). But the signals to build fat decreased only in ........ Read more »
