Machine learning algorithm helps unravel the physics underlying quantum systems

Posted: 29 Apr 2021 08:24 AM PDT

Scientists have developed an algorithm that provides valuable insights into the physics underlying quantum systems - paving the way for significant advances in quantum computation and sensing, and potentially turning a new page in scientific investigation.

Small generator captures heat given off by skin to power wearable devices

Posted: 29 Apr 2021 08:22 AM PDT

Scientists have developed a small, flexible device that can convert heat emitted from human skin to electrical power. In their research the team showed that the device could power an LED light in real time when worn on a wristband. The findings suggest that body temperature could someday power wearable electronics such as fitness trackers.

The shape of light changes our vision

Posted: 28 Apr 2021 11:09 AM PDT

The perception of light is extremely fast. But the analysis was carried out on molecules in solution in the laboratory. Scientists reproduced the experiment on mice, in order to observe the processing of light by a living organism in all its complexity. This study shows that light energy alone does not define the response of the retina. Its shape also has an impact on the signal sent to the brain to form an image.

How to get salt out of water: Make it self-eject

Posted: 28 Apr 2021 11:09 AM PDT

Researchers have uncovered a mechanism by which dissolved salts can crystallize in a way that makes it easy to remove them from surfaces, potentially helping to prevent fouling of metal surfaces.

Scientists harness molecules into single quantum state

Posted: 28 Apr 2021 08:37 AM PDT

Being able to build and control systems of quantum particles, which are among the smallest objects in the universe, is the key to developing quantum technology. That goal is now a step closer thanks to scientists who just figured out how to bring multiple molecules at once into a single quantum state -- one of the most important goals in quantum physics.

Major advance enables study of genetic mutations in any tissue

Posted: 28 Apr 2021 08:37 AM PDT

For the first time, scientists are able to study changes in the DNA of any human tissue, following the resolution of long-standing technical challenges. The new method, called nanorate sequencing (NanoSeq), makes it possible to study how genetic changes occur in human tissues with unprecedented accuracy.

Black hole-neutron star collisions may help settle dispute over Universe's expansion

Posted: 28 Apr 2021 07:24 AM PDT

A new study simulated 25,000 scenarios of black holes and neutron stars colliding, aiming to see how many would likely be detected by instruments on Earth in the mid- to late-2020s. The researchers found that, by 2030, instruments on Earth could sense ripples in space-time caused by up to 3,000 such collisions, and that for around 100 of these events, telescopes would also see accompanying explosions of light.

Switching to light

Posted: 27 Apr 2021 08:06 AM PDT

Researchers have developed a new optogenetic tool that simplifies a standard method in biotechnology: Instead of feeding E. coli bacteria with sugar as is commonly done, the researchers can now simply shine light on them.
