What is an individual?
It’s almost impossible to imagine biology without individuals — individual organisms, individual cells, and individual genes, for example. But what about a worker ant that never reproduces, and could never survive apart from the colony? Are the trillions of microorganisms in our microbiomes, which vastly outnumber our human cells, part of our individuality? The authors…

Observe.
A new device enables researchers to observe hundreds of neurons in the brain in real-time. The system is based on modified silicon chips from cameras, but rather than taking a picture, it takes a movie of the neural electrical activity. (1) Once a man tried to observe the cosmos. And he cannot stop ever since.…

Mathematics. World. Randomness.
Brownian motion describes the random movement of particles in fluids, however, this revolutionary model only works when a fluid is static, or at equilibrium. In real-life environments, fluids often contain particles that move by themselves, such as tiny swimming microorganisms. These self-propelled swimmers can cause movement or stirring in the fluid, which drives it away…

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…

The front door… Mind the front door…
Engineers have developed a navigation method that doesn’t require mapping an area in advance. Instead, their approach enables a robot to use clues in its environment to plan out a route to its destination, which can be described in general semantic terms, such as ‘front door’ or ‘garage,’ rather than as coordinates on a map.…
