Genetic secret to age women start menopause discovered

Research could lead to doctors being able to tell women how long they have got left to start a familyA series of genetic signals that influences the age women begin menopause has been identified, potentially paving the way to fertility treatment that could extend the natural reproductive lifespan of women.Researchers scanned the genes of more than 200,000 women and found nearly 300 genetic signals...

My favorite Martian image: Helicopter scouts ridge area for Perseverance

Ask any space explorer, and they'll have a favorite photo or two from their mission. For Kevin Hand, a scientist at NASA's Jet Propulsion Laboratory in Southern California and co-lead of the Perseverance rover's first science campaign, his latest favorite is a 3D image of low-lying wrinkles in the surface of Jezero Crater. The science team calls this area "Raised Ridges." NASA's Ingenuity Mars...

Researchers around the world are buzzing about a candidate superconductor

Since receiving a $25 million grant in 2019 to become the first National Science Foundation (NSF) Quantum Foundry, UC Santa Barbara researchers affiliated with the foundry have been working to develop materials that can enable quantum information-based technologies for such applications as quantum computing, communications, sensing, and simulation.

Using graphene foam to filter toxins from drinking water

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among these invisible substances is uranium. Leaching into water resources from mining operations, nuclear waste sites, or from natural subterranean deposits,...

Barriers to voting in elections linked to increased odds of being uninsured

Groups commonly targeted by voting restriction laws—those with low incomes, who are racial minorities, and who are young—are also less likely to be insured in states with more voting restrictions, according to a study by researchers at Columbia University Mailman School of Public Health and University of Alberta School of Public Health, Edmonton, Canada. However, those who are wealthier, white...

Increase in extreme precipitation in the northeast caused by Atlantic variability and climate change

Recent record-breaking rainfall across the northeastern United States is part of a larger trend. From Maine to West Virginia, the Northeast has seen an abrupt increase in extreme precipitation—heavy rain and snow resulting in about 1 to 2 inches of water in a day depending on location since 1996, which has coincided with warming sea surface temperatures in the North Atlantic. Northeast extreme...

Muscle protein that makes vertebrates more fit linked to limited lifespan

Researchers from Johns Hopkins Medicine say they have added to evidence that a protein called CaMKII improves strength, endurance, muscle health and fitness in young animals. Their experiments working with mice and fruit flies, however, found that the gene for CaMKII also contributes to an evolutionary tradeoff: increased susceptibility to age-associated diseases, frailty and mortality.
