FROSTI revolutionizes mirror control in gravitational-wave detectors, opening the door to a far deeper view of the cosmos. FROSTI is a new adaptive optics system that precisely corrects distortions in LIGO’s mirrors caused by extreme laser power. By using custom thermal patterns, it preserves mirror shape without introducing noise, allowing detectors to operate at higher sensitivities. This leap enables future observatories like Cosmic Explorer to see deeper into the cosmos...

Researchers have identified a molecular mechanism that helps explain why growing up in a stimulating environment enhances memory. In contrast, a lack of stimulation can impair it. The team from the Institute for Neurosciences (IN), a joint research center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), was led by researcher Ángel Barco.

Their study, conducted in mice and published in Nature Communications, demonstrates that the environment during childhood and ado...

Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes...

It’s well known that exercise is good for health and helps to prevent serious diseases, like cancer and heart disease, along with simply making people feel better overall. However, the molecular mechanisms responsible for preventing cancer or slowing its progression are not well understood. But, a new study, published in the Proceedings of the National Academy of Sciences, reveals how exercise can increase glucose and oxygen uptake in the skeletal and cardiac muscles, instead of allowing it to “feed” tumors.

Reduced tumor growth in exercised mice
To study how exercise-induced metabolic changes affect tumor growth, the research team injected mice with breast cancer cells and fed some of the mice a high-fat diet (HFD), consisting of 60% calories from ...
