A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint。 Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star。 Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists th
A study of 225 newborns suggests prenatal estrogen may have played a role in the evolution of larger human brains。 Boys with finger-length patterns linked to higher estrogen exposure before birth tended to have larger head circumferences, which are strongly associated with brain size。 The same connection was not seen in girls
Researchers have uncovered a surprising culprit behind sleep loss in Alzheimer’s disease: the brain’s own immune cells。 In mice with amyloid plaques, overactive microglia triggered inflammation that kept the brain from getting enough deep, restorative sleep。 Temporarily removing most of these cells restored more than two hours of sleep per day, eve
Hi, I designed and developed a spatial index that maps museum artefacts as connecting arcs/hyperlinks from their origin site to institutional location/sources。 The Index specifically looks at western/euro-american institutions and maps their collection categorised by them under Islamic art, Asian/African art, ethnological collections, Middle East,
The Chinese retailer allowed unsafe toys and counterfeit clothes to be sold on its site, says the EU
The latest estimates reveal that the majority of greenhouse gas emissions from large-scale events such as the FIFA World Cup stem from spectators traveling to host cities
Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes。 The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space。 By studying these laboratory samples, scientists can explore how organic chemistry unfo
