Raven personalities shape survival as human pressure grows at the Dead Sea‎

Along the stark and shimmering coastline of the Dead Sea, where desert cliffs meet one of the world's most extreme environments, a quiet drama is unfolding in the skies above. Fan-tailed ravens, intelligent, adaptable, and ever-watchful, are making life-or-death decisions every day. And according to new research, those decisions may come down to personality.

Physics-based AI model opens new frontiers in dielectric materials exploration‎

Predicting material properties remains a major challenge in materials science, as it often requires complex and computationally intensive calculations. In particular, understanding how materials respond to electric fields is essential for the development of next-generation electronic devices.

Mental math's shortcut—pupil dilation suggests people start solving before all numbers are in‎

People often solve simple arithmetic problems, such as basic addition, subtraction, multiplication or division, in their minds. The precise mental processes they rely on to solve these problems, however, are not entirely clear. Researchers at Université de Bordeaux and UCLouvain recently tried to better understand how humans tackle simple math mentally by tracking the size of their pupils.

More rhythm, less blues: Program boosts class behavior‎

From flash mobs to line-dancing to the Nutbush, experiencing rhythm and movement in a group context is known to boost mental and physical health in people of all ages. Now a University of the Sunshine Coast study published in Behavioral Sciences of more than 200 4-year-olds across South East Queensland has found and measured significant, specific benefits of the practice in preschool settings.

People with dark personality traits are naturally inclined towards leadership roles, finds new study‎

Can you tell if you're working with a narcissist or a psychopath? A new study suggests that people's job choices may offer some clues, especially in fields built on leadership and persuasion such as business, politics, and law, where such darker traits are more common. Those in creative fields or nature-focused work may be more likely to encounter individuals with a Machiavellian way of thinking, according to findings published in Personality and Individual Differences.

Zirconia thin films unlock new reversible nonpolar-to-polar mechanism‎

Researchers from National Taiwan University break traditional frameworks by unveiling a new symmetry-transition mechanism in ZrO2 thin films, achieving ultra-stable antiferroelectric behavior for up to 108 cycles.

How poison frogs built a chemical weapons system one evolutionary step at a time‎

Poison frogs are small and brightly colored amphibians that originate from Central and South America. As suggested by their name, these frogs can release highly toxic chemicals from their skin, which deter and neutralize predators.

Q&A: How research aims to improve bad housing data‎

Nicholas J. Marantz, associate professor of urban planning and public policy at UC Irvine, is investigating how effectively current data sources track changes in residential housing stock. His aim is to understand how policy changes, such as new zoning laws and broader housing market forces, influence the availability and creation of homes, particularly affordable homes.

Surprising link between metallicity and superconductivity uncovered in twisted trilayer graphene‎

Superconductivity is a state of matter characterized by an electrical resistance of zero, typically at very low temperatures. Past studies have found that in various materials, this unique state is accompanied by unusual electron arrangements.

The moon might be more prone to fires‎

Engineers love a good practical challenge, especially when it comes to spaceflight. But there's one particular challenge facing the crewed missions of the near future that scares mission planners above almost all others—fire. For decades, we've relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is much more complicated than an Earth-bound test provides for. A new paper from researchers at NASA's Glenn Research Center and Johnson Space Center and Case Western Reserve University details a planned mission to test the flammability of materials on the moon's surface—where they expect flame to act much differently than it does here on Earth.
