Chimpanzees are well known for their extraordinary diversity of behaviors, with some behaviors also exhibiting cultural variation. An international research team has investigated whether chimpanzee behavioral diversity is reduced under high human impact. By comparing sets of chimpanzee behaviors across a large number of social groups exposed to different levels of human disturbance, the scientists found a reduction in behavioral diversity when human impact was high.
Stars over eight times more massive than the sun end their lives in supernovae explosions. The composition of the star influences what happens during the explosion.
Researchers have developed a simple method that could turn ordinary semiconducting materials into quantum machines — superthin devices marked by extraordinary electronic behavior that could help to revolutionize a number of industries aiming for energy-efficient electronic systems — and provide a platform for exotic new physics.
Researchers have demonstrated it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.
Scientists placed seismometers on the McMurdo Ice Shelf and recorded hundreds of thousands of tiny ‘ice quakes’ that appear to be caused by pools of partially melted ice expanding and freezing at night. The phenomenon may be able to help scientists track glacier melting — and to help explain the breakup of large ice shelves.
Researchers have found that spider silk produces a strong twisting motion when exposed to humidity, and may be usable for future artificial muscles or actuators.
Fish provide a vital source of protein for over half the world’s population, with over 56 million people employed by or subsisting on fisheries. But climate change is beginning to disrupt the complex, interconnected systems that underpin this major source of food.
More than 10 miles into the backcountry of Yellowstone National Park, on the edge of the caldera, lives a high-elevation community so diverse that scientists call it “incredible, unique and truly weird.”
Dark matter may scatter against each other only when they hit the right energy, says international team of researchers in new study.
Everyone has secrets, but what causes someone to think about them over and over again? People who feel shame about a secret, as opposed to guilt, are more likely to be consumed by thoughts of what they are hiding, according to new research.
New research by neuroscientists shows that as neurons process information about texture from the skin, they each respond differently to various features of a surface, creating a high-dimensional representation of texture in the brain.
Scientists have quantitatively confirmed how energetic an auroral breakup can be. Using a combination of cutting-edge ground-based technology and new space-borne observations, they have demonstrated the essential role of an auroral breakup in ionizing the deep atmosphere. The research furthers our understanding of one of the most visually stunning natural phenomena.
A team of scientists has visualized meteorite components at resolution powers much higher than ever before. Their efforts resulted in a much better look at — and enhanced understanding of — substances inside carbonaceous chondrites, the organic-containing meteorites that land on Earth. These substances include hydrogen, carbon, nitrogen and water, all of which are needed for life.
Cold waters that sank in polar regions hundreds of years ago during the Little Ice Age are still impacting deep Pacific Ocean temperature trends. While the deep Pacific temperature trends are small, they represent a large amount of energy in the Earth system.
Most crops on the planet are plagued by a photosynthetic glitch, and to deal with it, evolved an energy-expensive process called photorespiration that drastically suppresses their yield potential. Researchers reportthat crops engineered with a photorespiratory shortcut are 40 percent more productive in real-world agronomic conditions.
Scientists from NASA’s New Horizons mission released the first detailed images of the most distant object ever explored — the Kuiper Belt object nicknamed Ultima Thule. Its remarkable appearance, unlike anything we’ve seen before, illuminates the processes that built the planets four and a half billion years ago.
Researchers for the first time apply catalytic chemical reactions to 2D sheets to generate flows that transform these sheets into mobile, 3D objects.
NASA’s New Horizons spacecraft flew past Ultima Thule in the early hours of New Year’s Day, ushering in the era of exploration from the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins of the solar system.
Researchers have devised a new model for the universe — one that may solve the enigma of dark energy. Their new article proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension.
Researchers have developed new dynamic DNA origami technology.
