If you partitioned the entire Earth, from just below the surface to the top of the atmosphere, into 1-kilometer-square chunks, there would be billions of them. Now run each of those cells through a series of complex physics equations, and you can see how the entire Earth system interacts and evolves in detail, one step at a time.
New evidence from gas seeping above volcanic rifts suggests Mars is not geologically dead deep inside, but merely sleeping. Fresh fissures along the Alba Mons region hint at active spots under the surface, where gases from inside the planet may be making their way up to the surface.
Brazil's "Dirty List," a public registry that names employers found to have violated anti-slavery laws, is a key component of the country's efforts to combat forced labor. Major meatpackers in Brazil signed sustainable sourcing commitments promising to not purchase cattle directly from ranchers on the Dirty List. But new research shows that ranchers have found ways around these restrictions, rerouting cattle through intermediaries and allowing cattle linked to forced labor to remain in domestic and international beef and leather supply chains.
University of Sydney researchers have made a breakthrough by directly observing hydrogen in the tiny spaces between the atoms in metal alloys. The world-first observation of hydrogen dissolving in these 'metal crystal lattices' offers fresh insights into why hydrogen can weaken metals and how more hydrogen-resistant materials might be developed.
Previous studies have shown that upon antigen stimulation, the T cell receptor (TCR) undergoes phase separation with the kinase Lck to mediate rapid T cell activation. However, the manner in which costimulating receptors regulate this process has remained unclear.
Bournemouth University (BU) archaeological research has revealed that Iron Age British ruler "Verica," who was central to the Roman invasion of Britain in A.D. 43, was in fact a woman. This discovery rewrites the history of early Roman Britain.
A rideshare driver picks up a passenger who makes repeated unwanted sexual comments. The ride ends, but the experience doesn't.
Artificial intelligence may be making employees faster and more productive, but it could also be quietly damaging their careers. A new study led by Samuel Meyers, a Ph.D. student, together with his adviser Dr. Yochanan Bigman of the Hebrew University of Jerusalem and Dr. Roman Briker of WHU—Otto Beisheim School of Management in Germany, suggests that workers who use ChatGPT and other AI tools may pay an unexpected professional price: their managers are less likely to trust them.
Entrepreneurs who struggle to recognize and make sense of their own emotions are less likely to feel attached to their businesses and less committed to achieving their goals, particularly in high-stress periods, according to new research from the University of Bath School of Management.
Rockefeller scientists have created the most comprehensive map to date of how essential genes interact in Mycobacterium tuberculosis (Mtb), the bacterium responsible for tuberculosis (TB). The unprecedented map reveals thousands of previously unknown genetic relationships, offering a new window into the inner workings of one of the world's deadliest pathogens.
The principle "Work smarter, not harder!" apparently also applies to controlling quantum materials with light. Many of their fascinating properties depend on how the atoms are arranged in the crystal. Ultrashort laser pulses can be used to alter these structures in a targeted way—the light first excites electrons, whose changed energy and dynamics exert forces on the atomic nuclei and can thereby set the atoms in motion. Such processes unfold within femtoseconds, a millionth of a billionth of a second.
NASA has successfully demonstrated technology designed to help spacecraft autonomously navigate to safe landing sites on the moon and on other planets. An Alta-X drone equipped with the agency's Safe and Precise Landing—Integrated Capabilities Evolution (SPLICE) guidance, navigation and control payload completed simulated lunar descent and landing maneuvers Aug. 27. The flight took place at Rogers Dry Lake near NASA's Armstrong Flight Research Center in Edwards, California.
In all likelihood, the Neanderthals had flat feet. But it was not a defect at all. Instead, it was the consequence of a precise functional strategy to reduce impact stress under heavy loads and maximize stability on mountainous or rough terrain.
Archaeologists have discovered the third-largest assemblage of Ice Age cave art ever found in Mediterranean Iberia in a region thought devoid of cave art, transforming our knowledge of Paleolithic European art.
A meta-analysis of empirical studies involving more than 31,000 participants has revealed the factors that affect the level of influence of so-called social media influencers. Those factors include credibility, expertise, attractiveness and perceived similarity to their followers. They are, the work shows, positively associated with the attitude of consumers toward the brands mentioned or promoted by those influencers and, in turn, their purchasing intentions. Details of the analysis are published in the International Journal of Internet Marketing and Advertising.
Across 10 states this Election Day, voters overwhelmingly backed restrictions on data center development or rejected measures that would have eased their construction
Fluorescent materials usually emit a single consistent color. They are typically made from dyes or metallic components. In contrast, researchers reporting in ACS Central Science have created carbon dots that can fluoresce in a range of colors under UV light, depending on the concentration and the liquid they're in. The team incorporated the new carbon dots into plastic decorations and used them to create a data encryption system.
A recent study published in Nature Electronics and carried out by researchers from nanoGUNE's Quantum Hardware research group, Quantum Motion, London Center for Nanotechnology, Imperial College London and the University of Cambridge introduces a new superinductor created within a silicon integrated circuit fabricated in a commercial complementary metal–oxide–semiconductor (CMOS) process.
Mermaids have inhabited world folklore and mythology for centuries. Ancient Babylonians worshiped Oannes, a human-fish hybrid; sirens populated Greek mythology; and fairy tales such as "The Little Mermaid" have made this figure a pop culture icon.
An international research project is bringing scientists closer to mapping the universe. The MeerKLASS Collaboration has reported its first measurement of the large-scale clustering of cosmic hydrogen, advancing a technique that could transform how cosmologists chart the universe.
