A new observational study demonstrates that increasing air dryness does not reduce photosynthesis in certain very wet regions of the Amazon rainforest, contradicting Earth System Models that show the opposite.
(Columbia University School of Engineering and Applied Science) Is the Amazon rainforest as sensitive to water stress as what the current models have been showing? Columbia Engineering researchers found that the models have been largely over-estimating water stress in tropical forests. While models show that increases in air dryness greatly diminish photosynthesis rates in certain regions of the Amazon rainforest, observational data results show the opposite: in certain very wet regions, the forests instead even increase photosynthesis rates in response to drier air.
Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer’s disease, than women who live in locations with lower levels, according to a new study.
Using computer models to generate a COVID-free 2020 for comparison, NASA researchers found that since February, pandemic restrictions have reduced global nitrogen dioxide concentrations by nearly 20 percent.
(University of Illinois Grainger College of Engineering) Deep learning, also called machine learning, reproduces data to model problem scenarios and offer solutions. However, some problems in physics are unknown or cannot be represented in detail mathematically on a computer. Researchers at the University of Illinois Urbana-Champaign developed a new method that brings physics into the machine learning process to make better predictions. The researchers used turbulence to test their method.
(ARC Centre of Excellence in Exciton Science) A new type of machine learning model will predict the efficiency of materials that can be used in next-generation organic solar panels, including ‘virtual’ compounds that don’t exist yet. The program is free and easy to use for scientists and engineers creating prototype devices.
