Bringing the sun into the lab

Why the sun's corona reaches temperatures of several million degrees Celsius is one of the great mysteries of solar physics. A 'hot' trail to explain this effect leads to a region of the solar atmosphere just below the corona, where sound waves and certain plasma waves travel at the same speed. In an experiment using the molten alkali metal rubidium and pulsed high magnetic fields, researchers...

New method to complete genetic data

Genome sequencing is now much cheaper than it was, but still accounts for a large part of the costs in animal and plant breeding. One trick to reduce these costs is to sequence only a very small and randomly selected part of the genome and to complete the remaining gaps using mathematical and statistical techniques. Researchers have developed a new approach to do this.

More insight into how vision works

Scientists have shed light on an important component of the eye: a protein in the rod cells of the retina which helps us see in dim light. Acting as an ion channel in the cell membrane, the protein is responsible for relaying the optical signal from the eye to the brain. If a genetic disorder disrupts the molecular function in a person, they will go blind. Scientists have deciphered the protein's...

3D semiconductor particles offer 2D properties

Researchers have discovered that the junctures at the facet edges of 3D semiconductor particles have 2D properties, which can be leveraged for photoelectrochemical processes -- in which light is used to drive chemical reactions -- that can boost solar energy conversion technologies.

Self-healing nanomaterials usable in solar panels and other electronic devices

The field of self-repairing materials is rapidly expanding, and what used to be science fiction might soon become reality, thanks to scientists who developed eco-friendly nanocrystal semiconductors capable of self-healing. Their findings describe the process, in which a group of materials called double perovskites display self-healing properties after being damaged by the radiation of an electron...
