New weapon in the fight against malnutrition

Malnutrition affects millions of people worldwide and is responsible for one-fifth of deaths in children under the age of five. Children can also experience impaired cognitive development and stunted growth. Now scientists have opened the doors to new research into malnutrition by creating an animal model that replicates the imbalance of gut bacteria associated with the difficult-to-treat disease. —> Read More

From pluripotency to totipotency

While it is already possible to obtain in vitro pluripotent cells (i.e., cells capable of generating all tissues of an embryo) from any cell type, researchers have pushed the limits of science even further. They managed to obtain totipotent cells with the same characteristics as those of the earliest embryonic stages and with even more interesting properties. —> Read More

Spiders quickly learn eavesdropping to gain ground on the mating competition

When it comes to courting, one common spider species is quick to learn, and that learning process involves eavesdropping on the visual cues of rivals to win their mate. Scientists report that when wolf spiders were shown videos of other leg-tapping, courting males paired with silk cues from females, they quickly learned to recognize the behavior as part of the courtship process — in as little as four days. —> Read More
