Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites — branch-like extensions that protrude from neurons — help to perform those computations.
Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems.
MIT chemists have discovered the structure of a protein that can pump toxic molecules out of bacterial cells. Proteins similar to this one, which is found in E. coli, are believed to help bacteria become resistant to multiple antibiotics.
Shortness of breath, persistent cough and fatigue are common COVID signs and symptoms. And the vast majority of people will be managing their symptoms at home.
As a cardiorespiratory physiotherapist, I help people with heart and breathing problems manage and recover from a range of illnesses.
First-responder cells launching the repair after a heart attack are so frantic about fixing the damage that they promote more inflammation than necessary, new research in mice suggests.
Many don’t get ADHD diagnosis that could lead to help
High school students who have trouble paying attention in class are more likely to admit to cheating, a new study shows.
In a discovery that could one day benefit people suffering from traumatic brain injury, Alzheimer’s disease, and schizophrenia, UT Southwestern researchers have identified the characteristics of more than 100 memory-sensitive neurons that play a central role in how memories are recalled in the brain.
Imagine you are in a meadow picking flowers. You know that some flowers are safe, while others have a bee inside that will sting you. How would you react to this environment and, more importantly, how would your brain react? This is the scene in a virtual-reality environment used by researchers to understand the impact anxiety has on the brain and how brain regions interact with one another to shape behavior.
A new paper in the journal Ethics and Human Research co-authored by Berkeley Public Health Professor of Bioethics and Medical Humanities Jodi Halpern and Lecturer Sharon E. O’Hara, among others, explores how scientists perceive the potential of CRISPR technology and how the transition of many researchers from bench science (making new discoveries in the lab) to translational science (using these new discoveries to create novel medical treatments) may affect the treatment of those with genetic conditions.

While Australian cricket fans celebrate their team’s triumph at the 2021 ICC Men’s T20 World Cup, the tournament’s results have sparked a debate over whether the team that bats second has a potentially match-winning advantage before a ball is even bowled.
