Goldilocks principle wrong for particle assembly: Too hot and too cold is just right

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. —> Read More Here

Earthquakes in the ocean: Towards a better understanding of their precursors

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. —> Read More Here

New antidepressant: Rapid agent restores pleasure-seeking ahead of other antidepressant action

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. —> Read More Here
