Why your ancestors would have aced the long jump

A 52-million-year-old ankle fossil suggests our prehuman ancestors were high-flying acrobats. For years, scientists thought the ancestors of today’s humans, monkeys, lemurs and apes were relatively slow and deliberate animals, using their grasping hands and feet to creep along small twigs and branches. But a new study suggests the first primates were masters at leaping […]

The turbulent healing powers of plasma

Non-equilibrium atmospheric pressure plasma can help heal wounds, destroy cancer cells and kill harmful bacteria. The jets of plasma that doctors might use, however, often become turbulent with the direction and velocity changing dramatically. Now, researchers have found this turbulence likely emerges from heat-induced sound waves generated at the plasma electrodes. This new insight is […]

The evolutionary origin of the gut

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal lineage, researchers have now come to conclusions which challenge the 150-year-old hypothesis of the homology (common evolutionary origin) of the germ layers that […]
