Scientists at the Smithsonian Tropical Research Institute (STRI) found that the fringe-lipped bat, known to eavesdrop on frog and toad mating calls to find its prey, learns to distinguish between palatable and unpalatable frogs and toads through experienc

Imagine a crocodile built like a greyhound—that's a sebecid. Standing tall, with some species reaching 20 feet in length, they dominated South American landscapes after the extinction of dinosaurs until about 11 million years ago. Or at least, that's wh

A new study comparing wild and zoo-housed Sumatran orangutans reveals that life in a zoo significantly alters how orangutans interact with their environment.

Some things just go together in your belly: peanut butter and jelly, salt and pepper, bacteria and bacteria-eating viruses. For the bacterial species that inhabit your gut, there's a frenzy of viruses called bacteriophages that naturally infect them. Alt

The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection was discovered by scientists from the Department of Living Matter Physics at the Max Planck Institute for

Scientists have discovered a new type of immune defense in E. coli bacteria that turns viral infection machinery against the virus itself. Named after the Chinese military strategist Kongming—who famously used enemy weapons to defeat them—the system revea

Researchers from Australia and China have identified crucial structural variations that determine seed size and weight in peanuts, paving the way for the development of higher-yielding crop varieties.

A team of researchers led by Prof. Xiao Jun from the Institute of Genetics and Developmental Biology (IGDB) of the Chinese Academy of Sciences has discovered a new way in which temperature can influence the fate of plant cells by regulating epigenetic mar

Extrachromosomal DNA (ecDNA) is a unique form of circular DNA that exists outside of normal chromosomes. Found exclusively in tumor cells, it often carries cancer-promoting genes (oncogenes) and is detectable in most human cancers.

Scientists at Northwestern University and University of California, Santa Barbara have created the first synthetic fragment of tau protein that acts like a prion. The "mini prion" folds and stacks into strands (or fibrils) of misfolded tau prote

Through intensive breeding, humans have pushed breeds such as pug dogs and Persian cats to evolve with very similar skulls and "smushed" faces, so they're more similar to each other than they are to most other dogs or cats.

Researchers at the Francis Crick Institute have shown that the Cryptosporidium parasite exports a protein into infected intestinal cells, altering the gut environment and enabling the parasite to survive and replicate.
