The centers will provide technical assistance and training to state departments of education, aiming to increase student achievement goals.
Researchers found that pre-eruptive mixing within magma chambers, triggered by older cooler magma mixing with younger hotter magma, is the common event before catastrophic eruptions. This discovery could prove invaluable in future hazard and risk assessment on islands prone to volcanic activity.
The university will extend its world-class structural biology facilities by developing a state-of-the-art instrument for the new synchrotron user facility. The grant aims to provide detailed structural information that can benefit the entire scientific community.
A recent study published in Frontiers found that veterans who smoke are more likely to experience cognitive impairment and are at a higher risk of relapse. The research controlled for genetic variables and showed that smokers performed worse on measures of learning, memory, and processing speed compared to non-smokers.
Researchers at Wake Forest Baptist Medical Center have isolated neural precursor cells from skeletal muscle tissue, which can survive in the brain and migrate to areas where neural stem cells originate. The cells also showed no signs of tumor formation, offering a potential alternative source for treating brain tumors and other central...
A study of 5,442 female health professionals found that combined folic acid, vitamin B6, and vitamin B12 supplements did not reduce the risk of colorectal adenomas. No association was seen between supplement intake and cancer risk despite previous observational studies suggesting potential protective effects.
Researchers have identified a novel signalling pathway controlling cellular energy metabolism, independent of the known hedgehog pathway. This discovery suggests that substances targeting this pathway could provide an easy and safe adjunct therapy for diabetes and obesity, resolving complications induced by cancer treatments.
A new study found that treatment for obstructive sleep apnea (OSA) significantly lowers blood pressure in men with hypertension. The study, published in the Journal of Clinical Sleep Medicine, suggests that OSA treatment can be beneficial even for patients with other chronic medical conditions.
