Period brain is real.

The truth has been buried for a very long time.

The record sheds light on the climate early humans experienced when they were spreading out of Africa.

Newborn pilot whales have been spotted mysteriously swimming among pods of orcas. Scientists are trying to puzzle out how the pilot whale calves got there and what happened to them.

NASA's PUNCH mission, a tiny constellation of four satellites, captured a photo of the moon drifting across the sky through a haze of sunlight. The mission is still undergoing commissioning and is expected to start science operations June 9.

"Nutritious foods could be a good strategy for maintaining brain health."

Millions of years of evolution have enabled some marine animals to grow complex protective shells composed of multiple layers that work together to dissipate physical stress. In a new study, engineers have found a way to mimic the behavior of this type of layered material, such as seashell nacre, by programming individual layers of synthetic material to work collaboratively under stress. The new material design is poised to enhance energy-absorbing systems such as wearable bandages and car bumpers with multistage responses that adapt to collision severity.

A team of health and environmental researchers affiliated with multiple institutions in Belgium, working together due to a request from health insurer Mutualités Libres, has found that converting parts of cities to low-emission zones (LEZs) improves air quality. In their study, published in the journal Environment International, the group compared air quality samples in LEZs with similar sites in other cities without LEZs.

Corals everywhere on the planet live in harmony with microscopic organisms. Many corals get their vivid colors from microscopic algae which lives inside the corals' tissue and provides the coral with food. Even in the water surrounding coral reefs, there is a microscopic soup of bacteria, archaea, and other types of microbes that respond to changes in the habitat and can indicate whether or not the coral reef is healthy.

Climate change is melting glaciers and permafrost in the mountains outside of Boulder, Colorado, exposing rocks and freeing up minerals containing sulfate, a form of sulfur, to flow downstream into local watersheds.

Researchers at the University of Colorado Boulder and Oak Ridge National Laboratory have developed a new way to identify genetic changes that help tiny oxygen-producing microbes survive in extreme environments. The findings outline a new experimental approach for learning how microbes and other types of cells, including human cells, respond and adapt to environmental stress.

As climate change and growing energy demands strain global systems, scientists are increasingly turning to passive cooling technologies—ways to cool objects or spaces without using electricity. One promising method is radiative cooling, which works by reflecting sunlight and releasing heat in the form of infrared radiation into space. But despite its potential, this method is limited by natural laws that cap how much heat can be emitted. Now, a proposed theoretical model has the potential to boost the power of radiative cooling, potentially changing the way we manage heat in a warming world.

In the natural world—where predators pounce, prey flee, and group members feed and sleep in solidarity—animal behavior is glorious in its variety. Now, new research suggests there may be an underlying architecture that orders the movements of animals as they go about their very different lives. And it's more widespread than previously imagined.

New research suggests that the negative effects of the ozone hole on the carbon uptake of the Southern Ocean are reversible, but only if greenhouse gas emissions rapidly decrease.

New research has linked sea level rise and an increase in flooding in the U.S. Northeast over the past 20 years to the breakdown of the Atlantic Meridional Overturning Circulation (AMOC).

New research from an international group looking at ancient sediment cores in the North Atlantic has for the first time shown a strong correlation between sediment changes and a marked period of global cooling that occurred in the Northern Hemisphere some 3.6 million years ago. The changes in sediments imply that profound changes in the circulation of deep water currents occurred at this time.

Artificial light, once a luxury, has become central to modern life, with its evolution spanning from fire to LEDs. Now, researchers have developed a new class of efficient light-emitting materials as promising candidates to be applied to lighten the darkness. They demonstrated easily accessible aluminum-based organometallic complexes that have the potential to be applied in optoelectronic devices.

Researchers have discovered how orange cats got their coats — and why so many of them are male. The coat color comes from a genetic mutation on the X chromosome of orange, calico and tortoiseshell cats.

More than 15 billion miles from home, Voyager 1's ailing thrusters were threatening to abort the craft's mission. Until NASA engineers brought them miraculously back to life.

Taste, pain, or response to stress—nearly all essential functions in the human body are regulated by molecular switches called G protein-coupled receptors (GPCRs). Researchers at the University of Basel have uncovered the fundamental mechanism for how such a GPCR works.

In an article published in Nature Communications, researchers from Uppsala Antibiotic Center, Uppsala University and SciLifeLab describe a fundamental mechanism of antibiotic resistance. What happens in a bacterium that is resistant to the antibiotic fusidic acid?

Prostaglandin E2 (PGE2), a bioactive lipid derived from arachidonic acid, mediates a broad range of physiological processes through four G protein-coupled receptor (GPCR) subtypes: EP1–EP4. While the high-resolution structures of EP2, EP3 and EP4 have been resolved, EP1 remained structurally uncharacterized due to its intrinsic instability, hindering detailed understanding of its Gq-mediated signaling.

Three 1,500-year-old burials in the Negev desert have pendants of bone and ebony that may depict the deceased individuals' ancestors.

A research team led by Prof. Wang Mingtai at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a finely tuned method for growing titanium dioxide nanorod arrays (TiO2-NA) with controllable spacing without changing individual rod size and demonstrated its application in high-performance solar cells.

A research team from the School of Engineering at the Hong Kong University of Science and Technology has developed a new computational model to study the movement of granular materials such as soils, sands and powders. By integrating the dynamic interactions among particles, air and water phases, this state-of-the-art system can accurately predict landslides, improve irrigation and oil extraction systems, and enhance food and drug production processes.
