Moonquakes shook Apollo 17’s landing zone—and they could challenge the safety of future lunar outposts. Scientists have discovered that moonquakes, not meteoroids, are responsible for shifting terrain near the Apollo 17 landing site. Their analysis points to a still-active fault that has been generating quakes for millions of years...

New research published in Nature Communications has linked a normal cellular process to an accumulation of DNA mutations in cancer and identified cancer-driving mutations in an underexplored part of the genome.

Led by Dr. Jüri Reimand of the Ontario Institute for Cancer Research (OICR), the study centers around a protein called TOP2B, part of a family of enzymes that serve an important function in cells and are targets of common cancer chemotherapies.

Strands of DNA are long and complex, and they often get looped and tangled. When that happens, TOP2B and other topoisomerase proteins make cuts to DNA strands to help untangle and repair them...

Cornell researchers have developed a new transistor architecture that could reshape how high-power wireless electronics are engineered, while also addressing supply chain vulnerabilities for a critical semiconductor material.

The device, called an XHEMT, includes an ultra-thin layer of gallium nitride built on bulk single-crystal aluminum nitride, a semiconductor material with low defect densities and an ultrawide bandgap—properties that allow it to withstand higher temperatures and voltages while reducing electrical losses.

The device was detailed in the journal Advanced Electronic Materials and the research was co-led by Huili Grace Xing, the William L...

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...
