Phys.org / Largest review finds formal ethics education improves students' moral reasoning
How important is it that kids learn to tell right from wrong? Businessman and former university chancellor David Gonski recently called for ethics classes to be rolled out in all Australian schools to boost social cohesion.
Medical Xpress / How the brain decides where to insulate its own wiring
In the complex circuitry of the brain, a fatty substance known as myelin plays a vital role in insulating neural wiring. It coats billions of axons in the brain and makes up about one-fifth of the organ in humans.
Phys.org / 9/11 responders passed effects of trauma to their children, study finds
Although it's been 25 years since the World Trade Center collapsed after terrorists flew commercial airplanes into each of the center's two towers, the trauma experienced by many first responders and recovery workers is still ...
Medical Xpress / Brain blood flow responds differently to pain and touch, mouse study finds
When the brain is stimulated, blood flow increases. For 30 years, functional magnetic resonance imaging (fMRI), one of the most powerful windows into the human brain, has operated on the basis of this connection. fMRI doesn't ...
Tech Xplore / Potential material for safer Li-ion batteries achieves record-high conductivity
Two years ago, a new material was reported to have an unusually large lithium-ion conductivity. Now, Nagoya University researchers have uncovered why it works so well and attained its record-high room temperature conductivity ...
Phys.org / Screening tool amplifies tiny changes in protein levels within cells
Imagine a brain teaser where the challenge is to spot the difference between two nearly identical sandcastles. The only difference? The removal of three grains of sand. Scientists face a similarly exasperating challenge when ...
Medical Xpress / Dozens of genes tied to OCD and tic disorders discovered
A Rutgers-led international collaboration has identified 36 genes that substantially raise the risk of obsessive-compulsive disorder (OCD) and chronic tic disorders—providing, two researchers said, the most detailed biological ...
Phys.org / Declining star formation not caused by simple 'fuel crisis,' new measurements suggest
The universe has been having fewer and fewer stellar "babies." Over the past 4.5 billion years, the rate of star birth has crashed to less than half of what it once was. But here's the twist: the most essential "fuel" for ...
Medical Xpress / Stress and depression, not heart damage, may drive long-term breast cancer fatigue
For breast cancer survivors, new research shows that feelings of depression and perceptions of psychological stress make the biggest difference in whether they experience fatigue up to two years after chemotherapy started.
Phys.org / Warming winters weaken New Hampshire forest's carbon sink over 20 years
Can we count on forests to continue absorbing the carbon dioxide that's warming our world? A new study from researchers at NAU and the University of New Hampshire says ... maybe not.
Phys.org / Los Angeles Basin map shows deep sediments that could amplify earthquake shaking
In computer simulations of the Big One—a large-magnitude earthquake that may occur along the San Andreas Fault in California—seismic waves ripple from the epicenter of a magnitude 7.8 earthquake near the Salton Sea into the ...
Phys.org / Growing bacteria line up single-file, then buckle in liquid crystals
When scientists study bacteria that are not in a Petri dish or a test tube but in environments that more closely mimic their actual microbial habitats, they often find delightfully unexpected behaviors. For Sujit Datta, a ...
