One Simple Brain Hack might Boost Learning and Improve Mental Health

Shifting from a high-pressure mindset to a curious one improves people’s memory.

New research from Duke found that people who imagined being a thief scouting a virtual art museum in preparation for a heist were better at remembering the paintings they saw, compared to people who played the same computer game while imagining that they were executing the heist in-the-moment.

These subtle differences in motivation—urgent, immediate goal-seeking versus curious exploration for a future goal—have big potential for framing real-world challenges such as encouraging people to get a vaccine, prompting climate change action, and even treating psychiatric disorders.

The findings appeared online July 25 in the Proceedings of the National Academy of Sciences.

Renewable Solar Energy can help Purify Water, the Environment

Chemists led by Beckman researcher Xiao Su have demonstrated that water remediation can be powered in part — and perhaps even exclusively — by renewable energy sources. Using electrochemistry to separate different particles within a solution (also known as electrochemical separation) is an energy-efficient strategy for environmental and water remediation: the process of purifying contaminated water...

Webb Detects Water Vapor in Rocky Planet-Forming One

This artist’s concept portrays the star PDS 70 and its inner protoplanetary disk. New measurements by NASA’s James Webb Space Telescope have detected water vapor at distances of less than 100 million miles from the star – the region where rocky, terrestrial planets may be forming. This is the first detection of water in the terrestrial region of a disk already known to host two or more protoplanets, one of which is shown at upper right.

Water is essential for life as we know it. However, scientists debate how it reached the Earth and whether the same processes could seed rocky exoplanets orbiting distant stars. New insights may come from the planetary system PDS 70, located 370 light-years away...

Inflammation Discovery could Slow Aging, Prevent Age-related Diseases

Inflammation discovery could slow aging, prevent age-related diseases
Age-related changes in whole-blood gene expression are associated with increased inflammatory gene transcription and decreased expression of genes encoding mitochondrial Ca2+ transport. Credit: Nature Aging (2023). DOI: 10.1038/s43587-023-00436-8

University of Virginia School of Medicine researchers have discovered a key driver of chronic inflammation that accelerates aging, a finding that could lead to longer, healthier lives and the possible prevention of age-related conditions such as deadly heart disease and devastating brain disorders.

The harmful inflammation is driven by improper calcium signaling in the mitochondria of certain immune cells, researchers found. Mitochondria are the power generators in all cells, and they rely heavily on calcium signaling.
