Perovskites show potential for valleytronics applications. Engineers at Rice University and Texas A&M University have found a 2D material that could make computers faster and more energy-efficient.

Their material is a derivative of perovskite — a crystal with a distinctive structure — that has the surprising ability to enable the valleytronics phenomenon touted as a possible platform for information processing and storage.

The lab of materials scientist Jun Lou of Rice’s Brow...

People with cancer who exercise generally have a better prognosis than inactive patients. Now, researchers at Karolinska Institutet in Sweden have found a likely explanation of why exercise helps slow down cancer growth in mice: Physical activity changes the metabolism of the immune system’s cytotoxic T cells and thereby improves their ability to attack cancer cells. The study is published in the journal eLife.

“The biology behind the positive effects of exercise can provide new insights into how the body maintains health as well as help us design and improve treatments against cancer,” says Randall Johnson, professor at the Department of Cell and Molecular Biology, Karolinska Institutet, and the study’s corresponding author.

Prior research has shown that physical activity can p...

NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has confirmed, for the first time, water on the sunlit surface of the Moon. This discovery indicates that water may be distributed across the lunar surface, and not limited to cold, shadowed places.

SOFIA has detected water molecules (H2O) in Clavius Crater, one of the largest craters visible from Earth, located in the Moon’s southern hemisphere...

A new nanocatalyst that recycles major greenhouse gases, such as carbon dioxide (CO2) and methane (CH4), into highly value-added hydrogen (H2) gas has been developed...
