Plant-based seafood alternatives should have similar flavors, textures and nutritional content to the foods they mimic. And recreating the properties of fried calamari rings, which have a neutral flavor and a firm, chewy texture after being cooked, has be

Researchers at Linköping University have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into

McGill University researchers, in collaboration with Mexican scientists, have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucatán Peninsula.

Northwestern Medicine investigators have developed first-of-its-kind eyedrops that use synthetic nanoparticles to help the eye regenerate cells that have been damaged by mustard keratopathy, or exposure to mustard gas, and other inflammatory eye diseases,

Populations of animals and plants separated by even thousands of miles can rise and fall together driven by ecological factors, a phenomenon scientists call "spatial synchrony."

A new carnivorous caterpillar that wears the remains of its prey has been dubbed the "bone collector."

Scientists from the Faculty of Physics and Applied Informatics at the University of Lodz have published an article on friction in the journal Small. Their research on "bismuth islands" moving on the surface of graphite confirmed the existence of

Sharks are often perceived as the ultimate beasts, an image largely imposed on them by the media. Yet, shark bites are rare—only around 100 or so happen every year, and just around 10% are fatal.
