A new category of heat waves is melting western US snowpack faster

Heat waves are not all created equal. While some bring dry heat that rapidly dries out crops, others carry a lot of moisture that can prevent sweat from evaporating off the skin. In new research published in the journal Science Advances, scientists have identified another type of heat wave that they call a

Satellite data reveal tropical forests respond differently to climate across continents

Satellite images can be used to estimate how much carbon forests store as aboveground biomass (AGB) and how biomass varies in different forests. In a study published in the journal Nature, a team of researchers affiliated with the Smithsonian Tropical Research Institute (STRI), the University of Maryland, NASA and the Universidade Federal dos Vales do Jequitinhonha e Mucuri, Brazil, analyzed 16 million 2020 NASA-GEDI satellite estimates of biomass from forests in the Amazon, the Congo Basin and

Reddit analysis finds AI trust narrowly exceeds distrust, 31% to 26%

Is generative artificial intelligence technology a helpful tool or a big problem? Nearly four years after ChatGPT became a household name, most people are either using AI applications or generally aware of what the technology can do. But understanding how much they actually trust the work it produces and the answers it provides remains an important question. New research from Drexel University, based on a longitudinal analysis of hundreds of thousands of Reddit posts since 2022, sheds light on t

A magnetic path to lower-power computing

From smartphones to data centers, modern electronics rely on billions of tiny switches that consume electricity every time they turn on or off. As global demand for computing continues to grow, so does the energy required to power it. Scientists are therefore searching for alternatives that can perform the same tasks while using far less energy.

Greater vegetable diversity needed for healthier diets and climate-resilient agriculture

In a study published in the Proceedings of the National Academy of Sciences, researchers show how a wider diversity of vegetables could help improve diets and strengthen agriculture against climate change. They use the term vegetable biodiversity to describe the full range of vegetable species, traditional varieties and their wild relatives.

Complex suicidal somersault behavior in male redback spiders may be explained by surprisingly simple genetics

The Australian redback spider (Latrodectus hasselti), a cousin of the North American black widow spider, is known to practice sexual cannibalism, which is somewhat common among spider species. However, the male Australian redback has also been observed facilitating the process with strange moves. Despite the complexity of these behaviors, a new study, published in Biology Letters, indicates that one of these behaviors arises from simple genetics, while another may be more complex.

Muon g-2 experiment places new constraints on a forbidden property of muons

A year after its final muon magnetic anomaly announcement, the Muon g-2 collaboration reports a new measurement of a different property of the muon: its electric dipole moment. The work is published on the arXiv preprint server.

Early hardship may shape how oxytocin influences altruism

While humans are inherently social beings, they can interact and connect with others in very different ways. For instance, while some people tend to be more altruistic, others are less prone to helping their friends, acquaintances or even complete strangers, particularly when it comes at a personal cost.

Shame, stigma, and culture prevent male intimate partner violence survivors from seeking help, study finds

Men are less likely than women to seek help after experiencing intimate partner violence, and new research from George Mason University found that the main barriers include viewing it as a private matter, fear of retaliation, shame and concerns about not being believed.

Protein-like nanoparticles sort themselves inside growing crystals, enabling controlled release

The tiny bones in your fingers withstand countless taps and swipes thanks to a precise blend of materials. Flexible collagen fibers form the framework, reinforced by hard calcium phosphate hydroxyapatite crystals. This is just one of countless examples in which living organisms weave organic materials directly into inorganic crystals with exquisite precision. In a recent study published in Nature Communications, scientists attempted to recreate such precise spatial arrangements in biomimetic com

Rapid warming may tip Atlantic circulation at 2

For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC) could come to a halt if the world warms too much. New research from Utrecht University shows that this picture is incomplete: The pace of warming also determines whether the AMOC stays stable.

Simple robot design exceeds human hand in some core motions

The human hand is a dexterous and versatile machine. Scientists have conventionally tried to replicate these traits in robots by copying the biological mechanics of the hand, resulting in complex and difficult-to-control structures. An alternative solution to these challenges was proposed in a new study published in Advanced Science: the BioflexBot, a novel robot that mimics and even exceeds core motions of the hand with a simple design.

African grasslands expanded 5 million year earlier than previously thought, molecular fossils suggest

The iconic grassland savannas of Africa are geographically extensive and important for both local fauna and the global climate. But where did they come from, and how will they change in the future? Ongoing warming, rising CO2 levels and shifting rainfall patterns are likely to profoundly change these ecosystems. These effects are difficult to predict because they can alter ecosystems in competing ways.
