Atherosclerosis is a disease in which fat, cholesterol, and other substances build up inside artery walls. This can lead to plaque formation, which can block arteries and cause heart attacks and strokes. Immune cells play a key role in cleaning the blood, by interacting with red blood cell extracellular vesicles…

Unlike previously thought, speech production and singing are supported by the same circuitry in the brain. Observations in a new study can help develop increasingly effective rehabilitation methods for patients with aphasia. The neural network related to speech is mostly located in the left cerebral hemisphere, while singing has been…

New research confirms fracking causes slow, small earthquakes or tremors, whose origin was previously a mystery to scientists. The tremors are produced by the same processes that could create large, damaging earthquakes. Fracking is the high-pressure injection of fluids underground to extract oil and natural gas. Though it is typically…

Platelets, or thrombocytes, are specialized cellular fragments that form blood clots when we get scrapes and traumatic injuries. Viral infections, autoimmune disease, and other conditions can cause platelet levels to drop throughout the body, termed thrombocytopenia. After a robust clinical and research collaboration, Stephan Moll, MD, and Jacquelyn Baskin-Miller, MD,…

The researchers also identified three proteins that are needed for the virus to carry out the invasion and have in turn synthesized molecules (potential drugs) that can target one of the proteins, potentially leading to new treatments for AIDS. “We have revealed a protein pathway that appears to have a…

Despite the many changes in school culture since the 1960s, a new study reveals that some things never change: life is harder for middle school students who are not attractive and for those who are not athletic. As children head back to school, the first-of-its-kind longitudinal study by Florida Atlantic…

A collaborative study undertaken by the Navarrabiomed Biomedical Research Center (Pamplona, Navarre), the Institute of Neurosciences CSIC-UMH (Sant Joan d’Alacant, Valencian Community) and IRB Barcelona (Barcelona, Catalonia) shows that the administration of ranolazine, a drug currently used to treat heart conditions, improves the efficacy of current therapies for melanoma, in…

Patients often experience functional decline after an ischemic stroke, especially due to the brain’s resistance to regenerate after damage. Yet, there is still potential for recovery as surviving neurons can activate repair mechanisms to limit and even reverse the damage caused by the stroke. How is it triggered though? In…

People living with cystic fibrosis (CF) will benefit from improved treatment as international experts produce clinical practice guidance for exercise assessments. The European CF Society Exercise Working Group (ECFS) document, led by Dr Zoe Saynor from the University of Portsmouth in England, provides comprehensive recommendations and instructions for health and…

Developing new materials requires significant time and labor, but some chemists are now hopeful that artificial intelligence (AI) could one day shoulder much of this burden. In a new study in the Journal of the American Chemical Society, a team prompted a popular AI model, ChatGPT, to perform one particularly…

CNN  —  Poland is planning to move around 10,000 troops to its eastern border with Belarus amid mounting concerns over Wagner forces in the region. Wagner troops have been stationed within Belarus – a close ally of Russia – in the wake of a short-lived rebellion carried out by the…

Ukraine has provided the Pentagon with a report about the use of controversial American cluster munitions in the fight with Russia, a Ukrainian official told CNN on Wednesday.  The official said the information transmitted to the Defense Department included both the number of rounds fired and the number of Russian…

Researchers are developing a way to incorporate one of the most human of characteristics — uncertainty — into machine learning systems. Human error and uncertainty are concepts that many artificial intelligence systems fail to grasp, particularly in systems where a human provides feedback to a machine learning model. Many of…

Orikhiv, Eastern Ukraine CNN  —  Rammed back into the bushes, out past destroyed Bradleys and ageing Humvees, the Soviet-era T72 lowers its turret to fire. Its targets are Russian positions, imperiled by Ukraine’s push south, just past the building over the horizon. Three rounds whistle into the distance, the tank…

Research from experts at Michigan Medicine, the Children’s Hospital of Philadelphia and Penn Medicine is breaking ground on new ways of treating blood disorders, such as sickle cell anemia, through gene therapy.
