New dark matter theory could solve multiple cosmic mysteries at once
Dark matter may be far more complicated than scientists once believed. A new study suggests it could consist of at least two different kinds of particles that slowly separate over time, with heavier particles sinking toward the centers of galaxies and lighter ones drifting outwar
Typhoons mix up bacteria and biochemistry
After a typhoon surprised a research cruise, scientists took advantage of the unique sampling opportunity to reveal rapid changes in bacterioplankton communities and biogeochemical cycling.
Yale scientists found a hidden network inside the eye
Researchers have discovered that the retina uses an unexpected communication network that lets separate visual pathways cooperate instead of working alone. A newly identified "commander" cell appears to coordinate this system, helping the eye detect faint details that might other
El Niño under way and threatens weather extremes, scientists say
An El Niño event has officially started, say US scientists, raising fears of extreme weather and higher temperatures. O recorte ajuda a contextualizar a pauta dentro de Agro.
Chinese sodium battery surprised scientists by matching key Tesla benchmarks
Researchers found that a Chinese sodium-ion battery performs far better than expected, with production quality and design features comparable to Tesla’s batteries. If engineers can improve cold-weather charging and energy density, sodium could become a cheaper and more abundant a
Tubulin prevents toxic brain protein clumps linked to Alzheimer’s and Parkinson’s
Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the p
Butterfly that barely ages could help unlock longevity secrets
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species. Even more surprising, some show little sign of physical decline as they age. Their unusual pollen-feeding lifestyle may play a role,
T. rex took 40 years to reach full size, scientists find
Tyrannosaurus rex may have been a much slower grower than scientists realized. A new study of 17 tyrannosaur fossils found that the giant predator likely took about 40 years to reach its full size of roughly eight tons, extending previous estimates by 15 years.
Scientists say most people need more protein than current guidelines suggest
A new review suggests that doing more exercise and eating more protein than current minimum recommendations may help people stay stronger, sharper, and more independent as they age. The goal isn't building a beach body—it's extending healthspan and maintaining the ability to full
Future astronauts could walk across rocks from deep inside the Moon
A colossal ancient collision may have left some of the Moon’s deepest secrets surprisingly close to future Artemis landing sites. By recreating the impact that formed the giant South Pole-Aitken basin—the Moon’s largest and oldest crater—scientists found that a low-angle strike f
A common vitamin could help fight one of the deadliest brain cancers
A clinical trial is exploring whether high doses of vitamin B3 could give patients with glioblastoma a better chance against the aggressive brain cancer. Scientists found that niacin may help revive immune cells that tumors shut down, allowing them to attack cancer more effective
