A new study in mice provides insights into why females in their reproductive years appear to be relatively protected from chronic kidney disease, a leading public health concern. The study reports that estrogen-regulated signaling promotes the regeneration of key filtration cells in female kidneys. The study also links pregnancy complications like preeclampsia to failures in this regenerative process. Chronic kidney disease (CKD) – which affects more than 10% of the global population – is a leading ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a proton. By making these extremely precise measurements, the US National Science Foundation-funded LIGO, which consists of two facilities—one in Washington and one in Louisiana—can detect undulations in space-time called gravitational waves that roll outward from colliding cosmic bodies such as black holes. LIGO ushered in the field of gravitational-wave astronomy beginning in 2015 when it made the first-ever direct detection of ...

In a Policy Forum, Ben Belton and colleagues discuss the rapidly growing use of drone technology in agricultural applications and the important, yet understudied, benefits and trade-offs involved. “There are strong indications that drones can raise the efficiency and productivity of farming, improve worker safety, and enhance rural livelihoods, but these impacts have yet to be evaluated rigorously,” Belton et al. write. “Applied interdisciplinary research and corresponding policy responses are urgently needed to steer the global ...

Following injury from a heart attack, immune cells called neutrophils release a peptide that punctures stressed heart cells and destabilizes their electrical activity. This triggers life-threatening arrhythmias. These findings offer a novel explanation – and potential therapeutic target – for these deadly cardiac events. Ischemic heart disease – cardiac damage caused by narrowed coronary arteries – is among the leading causes of death worldwide. It can lead to heart attacks and sudden cardiac death. When a coronary ...

Scientists are using artificial intelligence to understand escalating unrest in Italy’s Campi Flegrei, a volcanic area that is home to hundreds of thousands of people. Like adjusting a camera lens so a blurry image becomes clear, the new approach makes it possible for researchers to identify earthquakes that previous tools could not pick out from massive sets of seismic monitoring data.  The research, a collaboration between Stanford University, Italy’s National Institute of Geophysics and Volcanology (INGV) - Osservatorio Vesuviano, and ...

An international research team of photovoltaics scientists has taken a crucial step toward the industrialization of perovskite silicon tandem solar cells. They demonstrated that passivation of the perovskite top cell is possible in combination with textured silicon bottom cells featuring large pyramid size, which are the current industry standard for solar cells. Additionally, they discovered that the passivation affects the entire perovskite layer—unlike silicon, where surface treatment only influences the upper layers—leading to further efficiency improvements. The researchers from King Abdullah University of Science and ...

(Santa Barbara, Calif.) — The seas have long sustained human life, but a new UC Santa Barbara study shows that rising climate and human pressures are pushing the oceans toward a dangerous threshold. Vast and powerful, the oceans can seem limitless in their abundance and impervious to disturbances. For millennia, humans have supported their lives, livelihoods and lifestyles with the ocean, relying on its diverse ecosystems for food and material, but also for recreation, business, wellness and tourism. Yet the future of our oceans is worrying, ...
