In the fight against breast cancer, doctors have a new clue to watch out for. Sometimes, the skin of the breast can show signs of trouble, even before a tumor is spotted. This isn't about the main cancer itself, but about something else happening in the skin and tissues just under it. A recent stud
The brain's ability to update information is a complex process. Recent studies have focused on the role of dopamine and the striatum in this process. Researchers used a special type of MRI, called 7 Tesla fMRI, to scan the brain while people performed a memory task. They found that when new informat
Pulmonary hypertension (PH) is a serious condition where blood pressure in the lungs is too high. It often starts with issues in the lining of the pulmonary arteries. These arteries need to relax and widen to allow blood to flow easily. This relaxation is partly controlled by something called endoth
In the current political climate, NASA's advisory committees are facing significant changes. The Aerospace Safety Advisory Committee, mandated by Congress, has continued its work. However, the NASA Advisory Council and its various subcommittees have been on hold since the start of the second Trump a
Researchers have been exploring how to create DNA-based tools that can operate under extreme conditions. Most DNA tools are designed to work in environments similar to those found in living cells. The goal is to create tools that can function in unusual conditions. One recent effort f
Follicular lymphoma, or FL, is a tricky disease that's hard to cure. One of its defining traits is the addition of N-glycosylation, or N-gly, sequences in the immunoglobulin variable region. This happens early on, thanks to a process called somatic hypermutation. These N-gly sequences are rare in he
In Uganda, people with diffuse large B-cell lymphoma (DLBCL) face a tougher fight than those in wealthier nations. The main reason is that they do not have the same access to treatments. One treatment that has shown to improve survival rates is a combination of rituximab and chemotherapy. Rituxim
ADHD is a common issue among teenagers. It is not just about having a few symptoms. A proper diagnosis needs a mix of lasting signs. A recent study in Italy looked at this. They checked if bad habits are tied to both clear ADHD and milder signs. They found something interesting. Bad habits are not j
Athletes often face the risk of concussions during their careers. These injuries can lead to changes in the brain that aren't always visible right away. This is where the concept of subclinical neural alterations comes in. These are changes in the brain that don't show up on standard tests but can s
Tumor cells are sneaky. They can change their behavior based on their environment. Scientists wanted to know how certain proteins, called KLFs, help these cells adapt. They looked at three types of tumor cells from mice: 4T1, 4T07, and 67NR. These cells were put in different conditions to see how th
