Caecilians are serpent-like creatures, but they're not snakes or giant worms. The limbless amphibians, related to frogs and salamanders, favor tropical climates of Africa, Asia and the Americas. Most live in burrows of their own making; some are aquatic.
With colleagues from Brazil, Utah State University ecologist Edmund "Butch" Brodie, Jr. reports caecilians feature greatly enlarged...
From short 'tsiks' and 'ekks' to drawn-out 'phees' -- all the sounds produced by marmoset monkeys are made up of individual syllables of fixed length: that is the result of a study by a team of researchers headed by Dr. Steffen Hage of the Werner Reichardt Centre for Integrative Neuro-science (CIN) at the University of...
There are no such things as "wild" horses anymore.
Research published in Science today overturns a long-held assumption that Przewalski's horses, native to the Eurasian steppes, are the last wild horse species on Earth. Instead, phylogenetic analysis shows Przewalski's horses are feral, descended from the earliest-known instance of horse domestication by the Botai people of northern...
Glowing creatures like fireflies and jellyfish are captivating to look at but also a boon for science, as their bioluminescent molecules contribute to visualizing a host of biological processes. Now, scientists in Japan have supercharged these molecules, making them hundreds of times brighter in deep tissues and allowing for imaging of cells from outside the...
Bats are known to harbor highly pathogenic viruses like Ebola, Marburg, Hendra, Nipah, and SARS-CoV, and yet they do not show clinical signs of disease. In a paper published in the journal Cell Host & Microbe on February 22, scientists at the Wuhan Institute of Virology in China find that in bats, an antiviral immune...
Dramatic calorie restriction, diets reduced by 40 percent of a normal calorie total, have long been known to extend health span, the duration of disease-free aging, in animal studies, and even to extend life span in most animal species examined. Further research has shown that animals fed restricted-calorie diets are also better able to regenerate...
