A rare meteorite that crashed through a New Jersey roof contains evidence of ancient salty fluids, organic compounds, and amino acids from a primitive asteroid. Its pristine chemistry could offer new clues about how space rocks helped supply early Earth with some of the ingredien

A new nanostructured carbon design lets fuel-cell catalysts use tiny amounts of platinum while remaining remarkably stable and efficient. The breakthrough could help hydrogen fuel cells become a more practical way to power data centers, vehicles, and other energy-intensive techno

Atomically thin semiconductors could enable dramatically smaller and more efficient chips, but a stubborn problem at the boundary between materials has limited their performance. Researchers have now engineered that atomic interface to protect electron flow while still allowing e

The hit TV show confirms that sports lore is rife with powerful hexes. But there’s really nothing mystical about the dread and self-doubt they can induceAs the new season of Ted Lasso started, I was reminded of one of the show’s stranger storylines. When Dani “Football is life!”

Rice University engineers have developed a new strategy for controlling how therapeutic peptides are released from gelatin-based materials, a step that could make the small but powerful molecules more useful in tissue engineering and drug delivery.

Chemists have developed a catalyst that breaks a long-standing rule governing which molecules receive electrons during chemical reactions. By releasing electrons directly into solution, the technique could unlock reactions—and potentially useful new molecules—that were previously

Frequent cannabis users may wake up with unusually high levels of the stress hormone cortisol, suggesting their daily stress rhythms could be disrupted. Researchers say the finding raises questions about whether using cannabis for stress relief might, over time, interfere with th

While there are fears that people harvesting their food could put pressure on habitats, some ecologists suggest responsible foraging can boost conservation and biodiversityAngus Morton crouches behind a cricket pavilion in a London park to snip stinging nettles from an unkempt pa

Scientists say global blazes account for 10% of UK’s particle pollution – and climate crisis could make the problem worseSmoke rising above wildlife habitats, thousands of people evacuated and homes and livelihoods reduced to ashes – this is fast becoming the defining image of Br

Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions in which these phases are reached could help rese

One of the hallmarks of Alzheimer's disease is the accumulation of a peptide in the brain known as amyloid beta. A new study published in Nature Communications on July 22 has uncovered the atomic structure of the peptide in its harmful form. Mais do que repetir a manchete, o pont

Dwindling water levels on some of Germany's major rivers, worsened by heat and drought, are raising fears that badly constrained riverboat cargo traffic could deal yet another blow to the struggling economy. Mais do que repetir a manchete, o ponto aqui e entender o que essa mudan
