In the early 1930s, Swiss astronomer Fritz Zwicky observed galaxies in space moving faster than their mass should allow, prompting him to infer the presence of some invisible scaffolding—dark matter—holding the galaxies together. Nearly 100 years later, NASA’s Fermi Gamma-ray Space Telescope may have provided direct evidence of dark mattner, allowing the invisible matter to be “seen” for the very first time.

The elusive nature of ...

Detailed mapping of CD4⁺ T cells from children with systemic lupus erythematosus (SLE) has revealed distinct immune cell subsets with likely roles in disease pathogenesis, according to a study led by Weill Cornell Medicine investigators. The findings are poised to redirect lupus research and open the door to more precise therapies that avoid broad immune suppression.

Published in Nature Immunology, the study used single-cell RNA sequencing to profile CD4⁺ T-cell subtypes from children with SLE and healthy controls...

As artificial intelligence (AI) and smart gadgets become more common, our need for reliable power sources grows. Renewable energy options like solar and wind are great, but they depend on specific conditions. A research team led by Professor Dong-Myeong Shin from the Department of Mechanical Engineering at the University of Hong Kong (HKU) has developed a novel moisture-activated electricity generator (MEG) that offers a fresh, eco-friendly way to generate electricity—just from moisture in the air.

Their findings have been published in the journal Advanced Functional Materials in an article titled “Long-Lasting Moisture Energy Scavenging in Dry Ambient Air Empowered by a Salt Concentration-Gradient Cationi...

Boiling oceans may lurk beneath the ice of solar system’s smallest moons

Looking inside icy moons

The outer planets of the solar system are swarmed by ice-wrapped moons. Some of these, such as Saturn’s moon Enceladus, are known to have oceans of liquid water between the ice shell and the rocky core and could be the best places in our solar system to look for extraterrestrial life...
