Infrared NASA satellite imagery provided cloud top temperatures of thunderstorms that make up Tropical Storm Emilia. Comparing those NASA temperature readings with another satellite’s data obtained the following day, forecasters determined that Emilia had strengthened.

In 2015, exposure to particulate matter in sub-Saharan Africa led to 400,000 otherwise preventable infant deaths, according to a new Stanford study. The research published this week in Nature, finds that even modest improvements in air quality could lead to substantial reductions in infant mortality in developing countries.

Climate projections indicate more warming will occur in the Northeast than other sections of the United States, and that has implications for corn crops and dairy farms in the region by 2050, researchers warn.

Fabrics that resist water are essential for everything from rainwear to military tents, but conventional water-repellent coatings have been shown to persist in the environment and accumulate in our bodies, and so are likely to be phased out for safety reasons. That leaves a big gap to be filled if researchers can find safe substitutes.

Princeton researchers have developed a new computational method that increases the ability to track the spread of cancer cells from one part of the body to another.
