Sand dunes often accumulate in the floors of craters. In this region of Lyot Crater, NASA's Mars Reconnaissance Orbiter (MRO) shows a field of classic barchan dunes on Jan. 24, 2018. Just to the south of the group of barchan... Continue Reading →
Chronic social isolation has debilitating effects on mental health in mammals—for example, it is often associated with depression and post-traumatic stress disorder in humans. Now, a team of Caltech researchers has discovered that social isolation causes the build-up of a... Continue Reading →

With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a problem at the frontiers of cosmology — the... Continue Reading →
In a letter to the New England Journal of Medicine, a Massachusetts General Hospital (MGH) research team reports a remarkable treatment response in a patient participating in a clinical trial of a novel immune-system-based cancer therapy. Treatment with an investigational... Continue Reading →
Many diseases, including Parkinson’s disease, can be treated with electrical stimulation from an electrode implanted in the brain. However, the electrodes can produce scarring, which diminishes their effectiveness and can necessitate additional surgeries to replace them. MIT researchers have now... Continue Reading →
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Push it, and unlike every physical object in the world we know, it doesn’t accelerate in the direction it was pushed. It... Continue Reading →
What glows in the night? This night, several unusual glows were evident -- some near, but some far. The foreground surf glimmers blue with the light of bioluminescent plankton. Next out, Earth's atmosphere dims the horizon and provides a few... Continue Reading →
