Artificial intelligence makes great microscopes better than ever
To observe the swift neuronal signals in a fish brain, scientists have started to use a technique called light-field microscopy, which makes it possible to image such fast biological processes in 3D. But the images are often lacking in quality, and it takes hours or days for massive amounts of data to be converted into 3D volumes and movies. Now, EMBL scientists have combined artificial…
Why hotter clocks are more accurate
A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. Clocks pervade every aspect of life, from the atomic clocks that underlie satellite navigation to the cellular clocks inside our bodies. All of them consume energy and release heat. A kitchen clock, for example, does this by using up its battery. Generally the most accurate clocks require the…
Towards 2D memory technology by magnetic graphene
In spintronics, the magnetic moment of electrons (spin) is used to transfer and manipulate information. An ultra-compact 2D spin-logic circuitry could be built from 2D materials that can transport the spin information over long distances and also provide strong spin-polarization of charge current. Experiments by physicists at the University of Groningen (The Netherlands) and Colombia University (USA) suggest that magnetic graphene can be the ultimate…
Homing in on the smallest possible laser
At extremely low temperatures, matter often behaves differently than in normal conditions. At temperatures only a few degrees above absolute zero (-273 degrees Celsius), physical particles may give up their independence and merge for a short time into a single object in which all the particles share the same properties. Such structures are known as Bose-Einstein Condensates, and they represent a special aggregate state of…
Just a few atoms thick: New functional materials developed
They are 50,000 times thinner than a human hair, and just a few atoms thick: two-dimensional materials are the thinnest substances it is possible to make today. They have completely new properties and are regarded as the next major step in modern semiconductor technology. In the future they could be used instead of silicon in computer chips, light-emitting diodes and solar cells. Until now, the…
