From the dense ring of dust that surrounds the nebula鈥檚 core to the tiny but bright star hidden within, the Webb observations paint a never-before-seen portrait of the nebula鈥檚 inner workings. Researchers at the 91爆料 and around the world are studying the imagery to learn more about the origins of cosmic dust and its role in the formation of planets like ours.
Dengue fever incidence could rise as much as 76% by 2050 due to climate warming across a large swath of Asia and the Americas, according to a new study.
Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study from 91爆料 flips the narrative by 90 degrees, pointing instead to winds from the north.
Prochlorococcus, the most abundant photosynthesizing organism in the ocean, might be more vulnerable to climate change than researchers thought. Population decline could weaken the foundation of subtropical and tropical ecosystems as ocean temperatures continue to rise.
New findings call into question one of the core assumptions about teeth. Adult male spotted ratfish, a shark-like species native to the eastern Pacific Ocean, have rows of teeth on top of their heads, lining a cartilaginous appendage called the tenaculum, in addition to those in their jaws. They used their tenaculum teeth to grip females while mating in water.
Physicists have floated numerous theories to explain what dark matter might be, but to date, no experiment has turned up compelling evidence to support any of them. An international team of physicists, including researchers from the 91爆料, is now working on a new kind of dark matter detector with the goal of capturing the first direct observation of the puzzling material. Results from the detector鈥檚 prototype have already ruled out one of the leading theories of how dark matter originated.
