There are more than 1 million river basins carved into the topography of the United States, each collecting rainwater to feed the rivers that cut through them. Some basins are as small as individual streams, while others span nearly half the continent, encompassing, for instance, the whole of the Mississippi river network.

Healthy soil contributes to healthy crops. Farmers know this, so they do what they can to ensure their soil is in good shape. They send samples of their soil for lab testing to find out if it is low in any important nutrients. If it is, they can take steps to improve the health of their soil. These might include adding fertilizers or growing cover crops that feed the soil.

Progress on new artificial intelligence (AI) technology could make monitoring at water treatment plants cheaper and easier and help safeguard public health.

Building an ultra-energy efficient industrial-style building in a northern climate is no easy task, but the Wood Innovation Research Laboratory (WIRL) stands as proof it can be done.

The spring morning temperature in landlocked northern California warns of an incipient scorcher, but the small herd of piebald dairy cows that live here are too curious to care. Upon the approach of an unfamiliar human, they canter out of their barn into the already punishing sun, nosing each other aside to angle their heads over the fence. Some are black-and-white, others brown; all sport a pair of numbered yellow ear tags. Some are more assertive than others. One manages to stretch her long neck out far enough to lick the entire length of my forearm.

Climate change poses a serious threat to the United States’ internet infrastructure, with more than 4,000 miles of fiber optic cable expected to be under water within 15 years from just 1 foot of sea level rise, according to a new analysis by scientists at the University of Oregon and University of Wisconsin-Madison.

A magnetic wire used to snag scarce and hard-to-capture tumor cells could prove to be a swift and effective tactic for early cancer detection, according to a study by researchers at the Stanford University School of Medicine.

As Tropical Depression 11W was strengthening into Tropical Storm Son-tinh near the northern Philippines, the Global Precipitation Measurement mission or GPM core satellite analyzed its rainfall.

Eugenie Clark was a pioneer in shark biology, known around the world for her illuminating research on shark behavior. But she was a pioneer in another critical way, as one of the first women of prominence in the male-dominated field of marine biology.

Men may recover more quickly from influenza infections because they produce more of a key lung-healing protein, a study from scientists at Johns Hopkins Bloomberg School of Public Health suggests.
