In nature, organisms often support each other in order to gain an advantage. However, this kind of cooperation contradicts the theory of evolution proposed by Charles Darwin: Why would organisms invest valuable resources to help others? Instead, they should rather use them for themselves, in order to win the evolutionary competition with other species. A…

Ghosts…
What scientists thought was a planet beyond our solar system has ‘vanished.’ Though this happens to sci-fi worlds, scientists seek a more plausible explanation. One interpretation: instead of a planet, it could be a dust cloud produced by two large bodies colliding. (1) Ghost planets. One day there. One day gone. Don’t be impressed. You…

Being afraid of Nothing…
Scientists have created the fastest spinning object ever made, taking them a big step closer to being able to measure the mysterious quantum forces at play inside ‘nothingness’. The record-breaking object will pave the way for scientists to detect unfathomably small amounts of drag caused by the ‘friction’ within a vacuum. The science of nothingness…

Understanding how cells move autonomously is a fundamental question for both biologists and physicists. Experiments on cell motility are commonly done by looking at the motion of a cell on a glass slide under a microscope. In those conditions, cells are observed to “crawl” on the surface. Crawling is well understood: cells attach themselves to…
