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
As Mohenjo-daro prospered, the gap between its richest and poorest households actually shrank。 Its shared infrastructure, fair trade systems, and lack of powerful royal elites suggest that equality may have helped fuel the ancient city’s success
Weight loss is not simply a test of willpower。 The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss。 This biological “memory” helps explain why many people regain weight after dieting and why m
Ant parenting may have evolved from the same brain systems that once controlled hunger。 Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older。 Similar signals are involved in mammalian caregiving, suggesting that evolution may have f
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise。 Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes。 Researchers also found major genetic differences among isolated populations, suggesting new spec
Dying Sun-like stars may not fade away quietly。 As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction。 Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision
Animal bones preserved in South Australia’s underwater caves reveal distinctive clues shaped by darkness, algae, bacteria, and other environmental conditions。 The findings give scientists a powerful new way to reconstruct how ancient megafauna remains entered and survived in submerged cave systems
Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein。 In mice, arginine-rich diets led to fewer colon tumors and milder viral infections, suggesting a simple supplement could have powerful therapeutic potential
Scientists have built the first all-optical photonic time crystal, allowing them to reshape the behavior of terahertz light at extraordinary speeds。 The breakthrough could open the door to ultrafast computing, smarter communication systems, advanced imaging, and a new generation of highly tunable lasers
A massive magma reservoir has been detected deep beneath Tuscany, despite showing no obvious signs at the surface。 Scientists mapped the roughly 6,000-cubic-kilometer body using natural ground vibrations recorded by dozens of seismic sensors。 It poses no immediate danger, but the discovery reveals how enormous volcanic systems can remain hidden and
Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies。 Using archived data from the ALMA telescope in Chile, researchers conducted the observatory’s first SETI survey, searching for narrow signals that could indicate advanced technol
Scientists have successfully generated electricity with a hydrogen turbine that produces its own pressure through detonation waves instead of relying on a mechanical compressor。 The breakthrough could unlock dramatically more efficient power systems for clean energy and future aviation
Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs。 After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84。1-meter (276-foot) tree, the tallest known in East Asia
An exceptionally preserved snake fossil from Brazil reveals that early snakes were far more diverse than scientists once thought。 Detailed brain reconstructions show that Tametara mirim was adapted for burrowing, while another ancient snake was suited to life above ground。 Other fossils point to marine lifestyles as well
