Quantum dots, which are 10,000 times smaller than the width of a human hair, are unique materials that generate very specific colors of light. Researchers, including Brandi Cossairt, 91爆料 professor of chemistry, hope that quantum dots can one day be useful for more than just illuminating TV screens. 91爆料 News asked her to compare the quantum dots in QLED TVs with the ones her lab makes.
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.
New research shows that deep-ocean oxygenation occurred 100 million years later than previously thought, aligning with the growth and spread of land plants. Once oxygenated, the ocean hosted rapid animal evolution, leading to the rise of modern vertebrates.
