What makes someone better at switching between different tasks? Looking for the mechanisms behind cognitive flexibility, researchers have used brain scans to shed new light on this question. By studying networks of activity in the brain’s frontal cortex, a region associated with control over thoughts and actions, the researchers have shown that the degree to which these networks reconfigure themselves while switching from task to task predicts people’s cognitive flexibility....

Mary Poppins taught us that a spoonful of sugar makes the medicine go down. A bumblebee's favorite sugary drink may already be laced with medicine. And bees seem to dose themselves with medicinal nectar when they're suffering from a gut full of parasites.
Plants manufacture many chemical compounds to defend against attackers. Some of these are familiar to humans—like capsaicin, the potent weapon made by chili pepper plants. But not every animal enjoys painful food experiences like we do........ Read more »

The process of embryo implantation consists of multiple steps: blastocyst apposition, adhesion to uterine luminal epithelial (LE) cells, and removal of the epithelial cells encasing the blastocysts. How the blastocyst trophectoderm breaches the luminal epithelial barrier has been studied for decades, the mechanism of the abstraction of LE cells was not clearly understood. Since the[...]

Sodium formaldehyde sulfoxylate, a small sulfur-containing molecule with a propensity to give away its electrons (i.e. a strong reducing agent), has many names and many uses. One of its aliases, rongalite, comes from “rongeage", a French word meaning discharge. It refers to the industrial use of the molecule as a bleaching agent to remove colour from textiles (e.g. to create a white design on a dyed background) and other materials (e.g. to clear up discoloured sugar juice squeezed from plants)........
