JWST has captured unusually detailed images of gas feeding the supermassive black hole at the center of NGC 4696。 A vast filament appears to funnel material into an 800-light-year-wide spinning disk, where gas races around at up to 600 kilometers per second。 The findings suggest black holes may recycle their own fuel by heating gas with jets and la
Four nearby white dwarf stars have been discovered hiding in plain sight beside brighter red dwarf companions。 Hubble's ultraviolet observations finally revealed the long-hidden stellar remnants, including one just 25 light-years away that took nearly three decades to confirm。 The findings match long-standing predictions and suggest our corner of t
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 longevity-linked APOE2 gene appears to protect brain cells by reducing DNA damage and helping neurons recover from stress。 The finding could open a new path toward treatments that mimic APOE2’s defenses in people at higher genetic risk for Alzheimer’s
A single dose of psilocybin produced measurable changes in brain activity and possible changes in brain structure that lasted for up to a month。 Participants who experienced the greatest increase in flexible, varied brain activity also reported more personal insight and later improvements in well-being。 The findings suggest that the psychedelic exp
The future of artificial intelligence depends on finding more skilled humans for some very physical jobs
Researchers found that specific brain circuits help decide which jobs bees perform as they age。 When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties。 The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden in
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit。 The finding could open new avenues for understanding food cravings and potentially treating substance use disorder
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
Physicists from Heinrich Heine University Düsseldorf (HHU) have examined a fundamental property of quantum mechanics in collaboration with the German Aerospace Center (DLR)。 In the scientific journal Physical Review Letters, they show that this theory does not necessarily need to be formulated with imaginary numbers – real numbers can in fact also
