Asteroid Ryugu has a rich complement of organic molecules, according to a NASA and international team’s initial analysis of a sample from the asteroid’s surface delivered to Earth by Japan’s Hayabusa2 spacecraft...

Northwestern University researchers have developed a first-of-its-kind small, flexible, stretchable bandage that accelerates healing by delivering electrotherapy directly to the wound site.

In an animal study, the new bandage healed diabetic ulcers 30% faster than in mice without the bandage.

The bandage also actively monitors the healing process and then harmlessly dissolves—electrodes and all—into the body after it is no longer needed. The new device could provide a powerful tool for patients with diabetes, whose ulcers can lead to various complications, including amputated limbs or even death.

The research will be published online in the Feb. 22 issue of the journal Science Advances...

Imagine using an online banking app to deposit money into your account. Like all information sent over the internet, those communications could be corrupted by noise that inserts errors into the data.

To overcome this problem, senders encode data before they are transmitted, and then a receiver uses a decoding algorithm to correct errors and recover the original message...

A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun’s atmosphere, according to a new study.

In findings published in the journal Nature Communications, an international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun’s surface.

Researchers say the study’s findings could help scientists better understand the physical processes behind the energy release of solar flares – the solar system’s most powerful explosions.

“The discovery is unexpected,” said Sijie Yu, the...
