Ancient human teeth are telling secrets that may relate to modern-day health: Some stressful events that occurred early in development are linked to shorter life spans.
View ArticleGlobal warming slows coral growth in Red Sea
In a pioneering use of computed tomography (CT) scans, scientists at Woods Hole Oceanographic Institution (WHOI) have discovered that carbon dioxide (CO2)-induced global warming is in the process of...
View ArticleA new tool for mapping water use and drought
Farmers and water managers may soon have an online tool to help them assess drought and irrigation impacts on water use and crop development, thanks to the work of two U.S. Department of Agriculture...
View ArticleMost coral reefs are at risk unless climate change is drastically limited
Coral reefs face severe challenges even if global warming is restricted to the two degrees Celsius commonly perceived as safe for many natural and man-made systems. Warmer sea surface temperatures are...
