Salt can be good, and it can also be bad. Sprinkled on food, it makes things tastier, but it may also raise your blood pressure. Spread on winter roads, it can make driving safer, but the melting runoff contaminates nearby lakes and ponds.

In a study that gathered data from hundreds of lakes in the Northeast and the Midwest, a Dartmouth researcher and colleagues have found dramatic evidence of highway salt’s impact.

A new study by MIT climate scientists, economists, and agriculture experts finds that certain hotspots in the country will experience severe reductions in crop yields by 2050, due to climate change’s impact on irrigation.

The most adversely affected region, according to the researchers, will be the Southwest. Already a water-stressed part of the country, this region is projected to experience reduced precipitation by midcentury. Less rainfall to the area will mean reduced runoff into water basins that feed irrigated fields.

Seismologists at the University of California, Riverside studying earthquakes in the seismically and volcanically active Alaska-Aleutian subduction zone have found that “slow earthquakes” are occurring continuously, and could encourage damaging earthquakes.

Here's the scenario: you have sensitive data and a problem that only a quantum computer can solve. You have no quantum devices yourself. You could buy time on a quantum computer, but you don't want to give away your secrets. What can you do?

The sixth tropical depression of the Eastern Pacific Ocean hurricane season formed near southwestern Mexico and quickly strengthened into Tropical Storm Fernanda. NASA’s Aqua satellite provided infrared imagery of the strengthening storm.
