Nov. 21, 2023 — Eating more ultra-processed foods (UPFs) may be associated with a higher risk of developing cancers of upper aerodigestive tract (including the mouth, throat and esophagus), according to a new study. The authors of this international study, which analyzed diet and lifestyle data on 450,111 adults who were followed for approximately 14 years, say ...

Nov. 21, 2023 — Contrary to the commonly-held view, the brain does not have the ability to rewire itself to compensate for the loss of sight, an amputation or stroke, for example, say scientists. The researchers argue that the notion that the brain, in response to injury or deficit, can reorganize itself and repurpose particular regions for new functions, is ...

Nov. 23, 2023 — For 200 years, scientists have failed to grow a common mineral in the laboratory under the conditions believed to have formed it naturally. Now, researchers have finally pulled it off, thanks to a new theory developed from atomic simulations. Their success resolves a long-standing geology mystery called the 'Dolomite Problem.' Dolomite -- a key mineral in the Dolomite mountains in Italy, Niagara ...

Nov. 27, 2023 — The intensity and frequency of extreme rainfall increases exponentially with global warming, a new study finds. The analysis shows that state-of-the-art climate models significantly underestimate how much extreme rainfall increases under global warming -- meaning that extreme rainfall could increase quicker than climate models ...

Nov. 23, 2023 — Exposure to fine particulate air pollutants from coal-fired power plants (coal PM2.5) is associated with a risk of mortality more than double that of exposure to PM2.5 from other sources, according to a new study. Examining Medicare and emissions data in the U.S. from 1999 to 2020, the researchers also found that 460,000 deaths were attributable ...

Nov. 21, 2023 — In 2020 and 2021, California experienced fire activity unlike anything recorded in the modern record. When the smoke cleared, the amount of burned forest totaled ten times more than the annual average going back to the late 1800s. We know that wildlife in western forests evolved with changing habitat and disturbances like wildfire. Each species ...

Nov. 21, 2023 — When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and ...
