A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust。 Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets
Google's new API relies on parents to set age ranges in Family Link
China’s Tianwen-1 orbiter captured a faint but remarkable view of 3I/ATLAS as the interstellar comet raced past Mars。 The images reveal its tail and glowing coma, offering scientists a glimpse of material born beyond our solar system
MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts。 Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals。 In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago。 The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars。 The bombardment may explain ancient lunar craters and could have contributed to majo
Gold may have a secret self-defense system that helps it resist tarnishing。 Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold。 Beyond explaining why gold jewelry stays bright for generations, the finding could help sci
The asteroid that wiped out the dinosaurs was likely an exceptionally rare CO chondrite from a distant region of the solar system。 Its unusual chemistry suggests that planet-cooling dust and debris, rather than sulfur inside the asteroid, may have delivered the deadliest blow
Europa’s hidden ocean has made the icy moon one of the solar system’s most promising places to search for habitable conditions。 Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future spacecraft could more easily study。 New simulations suggest that journey is unlikely because turbulent
Deep beneath Japan’s mostly submerged Kikai caldera, scientists have discovered a vast magma reservoir that appears to be filling again。 The volcano produced the largest eruption of the Holocene 7,300 years ago, and seismic surveys now show that fresh magma has likely entered the same underground system responsible for that catastrophe
Researchers found that insulin-producing cells depend on a team of helper proteins to keep insulin production on track。 When one key partner was missing, damaged proteins built up and the cells made less insulin。 Strengthening this system could offer a new way to protect the pancreas as diabetes progresses
As some executives fret over the safety of new A。 systems, protecting against them could be a big business for tech companies
Signals traveling from the gut to the brain may help turn meals into lasting memories。 Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value。 Blocking the vagus nerve erased this effect and made it harder for the animals to remember where food had been located
A new AI-powered blood test could give people a remarkably early warning of serious heart and circulation problems。 Developed by researchers at the University of Hong Kong, CardiOmicScore analyzes thousands of proteins and metabolites to estimate the risk of six major cardiovascular diseases, including heart attack, stroke, heart failure, and atria
A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination。 In a small pilot trial, researchers gave spermidine supplements to adults over 65 following their third COVID-19 vaccine dose。 The biggest improvements appeared among people whose immune sys
A new study suggests the brain begins making decisions much earlier than scientists previously thought。 Researchers found that even primary sensory regions are influenced by higher brain areas through rapid feedback loops, rather than simply passing information forward。 This more dynamic view of brain function could help engineers design future AI
