The research suggests that ITS can reach struggling students through private learning opportunities, and future models ...
Researchers recreated quark-gluon plasma at RHIC, studying matter in its earliest form and gaining insights into the universe's evolution. The project also improves nuclear equipment training for young researchers, with applications in cancer radiotherapy and material analysis.
Researchers developed a brain-to-movement system called BrainGate, which enabled a paralyzed man to control objects using only his thoughts. The pilot clinical trial findings show that movement signals persist in the primary motor cortex long after a spinal cord injury, allowing for direct and successful control of external devices.
Researchers found that parasites dominated the links between species in food webs, with a significant impact on ecosystem stability. The study also revealed new patterns, including increased vulnerability of mid-trophic level animals to parasites and predators.
A recent University of Cambridge study found that managerial ability and effort play little part in securing and maintaining high-level jobs. Instead, reputation is largely determined by the team's performance and luck, which can impact job security.
A university health physicist offers radon testing as a campus community service, providing long-term testing kits to residents. The program aims to provide accurate information and reassurance to homeowners concerned about radon levels in their homes.
A study of over 3600 adults found that narrower arterioles and wider venules were associated with increased risk of coronary heart disease. The results suggest that retinal photography may be a useful non-invasive method for assessing this risk, particularly in women.
Researchers at University of California - San Diego found that mechanical stretching activates cellular protein JNK, damaging cells and contributing to atherosclerosis. This discovery may help design better treatment approaches for cardiovascular disease.
A cohort of over 138,000 adults in Denmark found that those living alone have a twofold increased risk of severe angina and heart attack. Poor education, pension, age, and social isolation are key factors contributing to this increased risk.
Researchers at MGH and Cyberkinetics have successfully linked a paralyzed patient's thoughts to electronic impulses, allowing him to control devices such as a computer cursor and prosthetic hand. The breakthrough uses the BrainGate Neural Interface System, which translates brain signals into electronic commands.
Scientists at the University of Pennsylvania School of Medicine have isolated a novel population of multipotent adult stem cells from human hair follicles. These cells can differentiate into nerve cells, smooth muscle cells, and melanocytes, offering potential treatments for various disorders.
University of Illinois researchers found unexpected two-way communication between blood stem cells and T cells, changing their fate. This loop may lead to a strong immune response, increasing the risk of graft-versus-host disease or rejection.
