Ancient Mars boasted abundant water, but the cold and dry conditions of today make liquid water on the Red Planet seem far less probable. However, the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) detected ...

At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the ...

When climate change is discussed, whether at UN climate summits, in company boardrooms or in the media, the focus is often on mitigation (cutting greenhouse gas emissions to achieve net zero). Adaptation, the practical steps ...

The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense X-ray pulses from accelerator-based ...

When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhance the membrane's permeability, and help isolate the desired ...

Current cardiac screening tools used to prevent heart attacks fail to identify nearly half of the people who are actually at risk of having one, according to a new study led by Mount Sinai researchers.

Cornell researchers have found that a new DNA sequencing technology can be used to study how transposons move within and bind to the genome. Transposons play critical roles in immune response, neurological function and genetic ...

Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviors in mice, even when natural rewards such as food or social contact are available. The study ...

Some people may worry about being bitten by a snake or spider, but have you ever considered what would happen if a small black hole tried to pass through your body?

Whether you're a home gardener or an industrial farmer, you might be familiar with mulching films—plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these ...

Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune "attack" cells ...

Let's get one thing out of the way: All hummingbirds fight. Most species fight for food, using their tiny bodies and sharp bills to force competitors away from flowers. But the green hermit hummingbird, which lives primarily ...
