Researchers developed a silk fabric, which is barely thicker than a human hair, that can suppress unwanted noise and reduce noise transmission in a large room.
In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, according to researchers. This peak is one of the main determinants of fracture risk later in life. After reaching this peak, a person's bone density remains roughly stable for a couple of decades. Then, when women enter the menopausal transition, they experience accelerated bone loss. Men also experience bone density decline as they age. Sleep patterns also evolve over time.
Tipping points in the climate system can be the result of a slow but linear development. However, they can also be accompanied by a 'flickering', with two stable climatic states that alternate before a final transition occurs -- and the climate tips permanently.
Emergency departments nationwide are overcrowded and overtaxed, but a new study suggests artificial intelligence (AI) could one day help prioritize which patients need treatment most urgently.
Using artificial intelligence, scientists have developed a powerful predictive model for identifying the most potent cancer killing immune cells for use in cancer immunotherapies.
