Cracks on Europa sport traces of ammonia

The search for life-supporting worlds in the solar system includes the Jovian moon Europa. Yes, it's an iceberg of a world, but underneath its frozen exterior lies a deep, salty ocean and a nickel-iron core. It's heated by tidal flexing, and that puts pressure on the interior

A silent brain disease can quadruple dementia risk

Researchers studying nearly 2 million older adults found that cerebral amyloid angiopathy sharply raises the risk of developing dementia. Within five years, people with the condition were far more likely to be diagnosed than those without it. The increased risk was present even

Moving closer to 'true' equine IVF for clinical use

Three years ago, Penn Vet researchers reported a major breakthrough in equine assisted reproduction. Katrin Hinrichs, Harry Werner Endowed Professor of Equine Medicine, and colleagues developed a technique that would allow successful conventional in vitro fertilization (IVF)

How topological surfaces boost clean energy catalysts

The oxygen reduction reaction (ORR) is a key process in fuel cells and metal-air batteries, technologies expected to play a central role in a low-carbon energy future. However, ORR proceeds slowly on most materials, limiting efficiency and increasing costs. Finding catalysts

Scientists have identified unique sounds for 8 fish species

Have you ever wished you could swim like a fish? How about speak like one? In a paper recently published in the Journal of Fish Biology, our team from the University of Victoria deciphered some of the strange and unique sounds made by different fish species along the coast of

How to cut harmful emissions from ditches and canals

Ditches and canals are the underdog of the freshwater world. These human-made waterways are often forgotten, devalued, and perceived negatively—think "dull as ditchwater." But these unsung heroes have a hidden potential for climate change mitigation, if they're managed correctly.

Alzheimer’s scrambles memories while the brain rests

When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain cells lose their stability, and

Middle age is becoming a breaking point in the U.S.

Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. These troubling trends stand
