Virtual treasure hunt shows brain maps time sequence of memories

People have little difficulty remembering the chronology of events, determining how much time passed between two events, and which one occurred first. Apparently, memories of events in the brain are linked when they occur closely together. Using an experiment that combines virtual reality and brain scan technology, Jacob Bellmund and Christian Doeller from the Max Planck Institute for Human Cognitive […]

Targeting a blood stem cell subset shows lasting, therapeutically relevant gene editing

In a paper published in the July 31 issue of Science Translational Medicine, researchers at Fred Hutchinson Cancer Research Center used CRISPR-Cas9 to edit long-lived blood stem cells to reverse the clinical symptoms observed with several blood disorders, including sickle cell disease and beta-thalassemia. It’s the first time that scientists have specifically edited the genetic makeup of a specialized subset […]

Data shows flood of opioids across US, many of them generics

The maker of OxyContin has been cast as the chief villain in the nation’s opioid crisis. But newly released government figures suggest Purdue Pharma had plenty of help in flooding the U.S. with billions of pills even as overdose deaths were accelerating. Records kept by the federal Drug Enforcement Administration show that 76 billion oxycodone and hydrocodone pills—the vast majority […]

Study shows widespread global implementation of WHO’s ‘Treat All’ HIV recommendation

A new study published in the Journal of the International AIDS Society shows that the World Health Organization’s (WHO) 2015 recommendation for immediate treatment of all people living with HIV has become the standard of care across HIV clinics in countries around the world. While most countries have adopted the WHO’s “Treat All” recommendation, the extent to which these guidelines […]

New evidence shows cytotoxic T cells can identify, invade, and destroy targets of large mass like T. gondii tissue cysts

CD8+ cytotoxic T lymphocytes can kill host cells infected with various microorganisms as well as single individual cancer cells through direct cell-to-cell contact, but their ability to destroy a target of large mass remains unexplored. A study in The American Journal of Pathology provided novel evidence on the capability of the immune system to eliminate large parasite-filled cysts associated with […]

Study shows that artificial neural networks can be used to drive brain activity

MIT neuroscientists have performed the most rigorous testing yet of computational models that mimic the brain’s visual cortex. Using their current best model of the brain’s visual neural network, the researchers designed a new way to precisely control individual neurons and populations of neurons in the middle of that network. In an animal study, the team then showed that the […]

Brains of blind people adapt to sharpen sense of hearing, study shows

Research has shown that people who are born blind or become blind early in life often have a more nuanced sense of hearing, especially when it comes to musical abilities and tracking moving objects in space (imagine crossing a busy road using sound alone). For decades scientists have wondered what changes in the brain might underlie these enhanced auditory abilities. […]

Gallery shows how women use animal skins, cow dung, cloth to manage periods

The charity reported that one in nine people don’t have clean water close to home and one in three don’t have a decent toilet of their own. As part of the gallery, WaterAid spoke to some of these women who revealed what methods they use. Limpo, a 22-year-old from Zambia uses dried up cow dung. She cuts them into small […]

Depression: gene test shows which children are at risk

Many children and young people Depression is detected, is often too late. Medical scientists have now succeeded for the first time on the basis of a genetic profile, the risk of serious disease predict. In Germany, more than half of the children and adolescents who suffer from Depression are not treated in a timely manner. An international team of researchers […]

Research shows impact of poverty on children’s brain activity

Children born into poverty show key differences in early brain function, according to new research from the University of East Anglia. Researchers studied the brain function of children aged between four months and four years in rural India. They found that children from lower-income backgrounds, where mothers also had a low level of education, had weaker brain activity and were […]
