New microscopes unravel the mysteries of brain organization: Researchers around the world share their stunning images and insights: The open source mesoSPIM Initiative

The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today in Nature Methods. The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever […]

Pinpointing how cells regulate long-lasting memories

The brain has a knack for safekeeping our most treasured memories, from a first kiss to a child’s birth. In a new study in mouse cells, Columbia neuroscientists have mapped some of the molecular machinery that helps the brain maintain these kinds of long-term memories. By observing the activity of nerve cells of the brain, called neurons, that were extracted […]

Faulty brain circuits repaired using nanotechnology: Possible new drug targets for dementia and intellectual disability

Working with mouse and human tissue, Johns Hopkins Medicine researchers report new evidence that a protein pumped out of some — but not all — populations of “helper” cells in the brain, called astrocytes, plays a specific role in directing the formation of connections among neurons needed for learning and forming new memories. Using mice genetically engineered and bred with […]

When a fix for one vision problem causes another

As we age, our eyes lose their ability to focus up close. It’s a condition called presbyopia, and it’s both extremely common and relatively easy to fix, with solutions like reading glasses, bifocals, or progressive lenses. Another common correction, called monovision, solves the problem with different lenses in each eye, one that focuses nearby, the other that focuses far away. […]

‘It’s Gigantic’: A New Way to Gauge the Chances for Unresponsive Patients

Doctors have known for years that some patients who become unresponsive after a severe brain injury nonetheless retain a “covert consciousness,” a degree of cognitive function that is important to recovery but is not detectable by standard bedside exams. As a result, a profound uncertainty often haunts the wrenching decisions that families must make when an unresponsive loved one needs […]

Majority of people return lost wallets – here’s the psychology and which countries are the most honest

Honesty is one of the traits we value most in others. We often assume it is a rather rare quality, making it important for us to find out who we can actually trust in this selfish world. But according to new research, there’s no need to be so cynical—it turns out most people in the world are honourable enough to […]

How bosses react influences whether workers speak up

Speaking up in front of a supervisor can be stressful — but it doesn’t have to be, according to new research from a Rice University psychologist. How a leader responds to employee suggestions can impact whether or not the employee opens up in the future. Danielle King, an assistant professor of psychology at Rice, is the lead author of “Voice […]

Seeing disfigured faces prompts negative brain and behavior responses: Brain imaging study finds negative implicit biases against individuals with scars, birthmarks and other facial differences

People with attractive faces are often seen as more trustworthy, socially competent, better adjusted, and more capable in school and work. The correlation of attractiveness and positive character traits leads to a “beautiful is good” stereotype. However, little has been understood about the behavioral and neural responses to those with facial abnormalities, such as scars, skin cancers, birthmarks, and other […]

Unlike men, women’s cognitive performance may improve at higher room temperature

Women’s performance on math and verbal tests is best at higher temperatures, while men perform best on the same tests at lower temperatures, according to a study published May 22, 2019 in the open-access journal PLOS ONE by Tom Chang and Agne Kajackaite from the USC Marshall School of Business, Los Angeles, USA, and the WZB Berlin Social Science Center, […]

Exaggerated physical differences between male and female superheroes

Superheroes like Thor and Black Widow may have what it takes to save the world in movies like Avengers: Endgame, but neither of their comic book depictions has a healthy body mass index (BMI). New research from Binghamton University and SUNY Oswego found that, within the pages of comic books, male superheroes are on average obese, while females are on […]
