There are thousands of American soldiers’ bodies still interred in North Korea — more than 50 years after the Korean War. Trace explains why they have not been recovered by the military, and whether anything can be done to bring them back home.
Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of scientists has found. Their discovery points to new ways to create “smart materials,” cutting-edge materials that adapt to their environment by taking new forms, and to sharpen the detail of 3D printing.
New research offers the first theoretical model that, based on fluid-related processes, explains the seismic precursors of an underwater earthquake. Using quantitative measurements, this innovative model established a link between observed precursors and the mainshock of an earthquake. The results open a promising avenue of research for guiding future investigations on detecting earthquakes before they strike.
A drug being studied as a fast-acting mood-lifter restored pleasure-seeking behavior independent of — and ahead of — its other antidepressant effects. Within 40 minutes after a single infusion of ketamine, treatment-resistant depressed bipolar disorder patients experienced a reversal of a key symptom — loss of interest in pleasurable activities — which lasted up to 14 days. Brain scans traced the agent’s action to boosted activity in areas at the front and deep in the right hemisphere of the brain.
The X-29, an American experimental aircraft has inspired quantum computing researchers in a development which will bring the technology out of the lab.
Physicists have built a tractor beam that can repel and attract objects, using a hollow laser beam, bright around the edges and dark in its center. It is the first long-distance optical tractor beam, 100 times larger than previous ones.
How did life originate? And can scientists create life? These questions not only occupy the minds of scientists interested in the origin of life, but also researchers working with technology of the future. If we can create artificial living systems, we may not only understand the origin of life — we can also revolutionize the future of technology.
