Loneliness and cognitive performance were related in the short term for older adults, according to a new study. For years, research has shown that older adults who are lonely are at greater risk for cognitive decline and conditions like Alzheimer's disease. Those studies, however, generally treated loneliness as a stable trait of someone's life, but

Obesity causes insulin resistance by increasing activation of the sympathetic nervous system and the release of the stress hormone norepinephrine, according to a new study. A study from Rutgers Health and other institutions indicates that stress hormones -- not impaired cellular insulin signaling -- may be the primary driver of obesity-related diabetes. The paper in

Research shows that a newly-developed wireless EKG patch is as accurate, if not more accurate, than results from traditional EKG machines. The device is known as the EKG Patch Solution. Worldwide, over 300 million electrocardiograms (EKGs) are performed each year, with one third of those taking place in the United States. Despite being so widely

Forming memories around shared experiences, whether something fun like grabbing a pizza or as emotionally straining as an employee strike, has a way of binding people together. But it could also motivate those performing different roles within the same company to socialize more and strengthen their working relationships, according to new research. In an office

The American Heart Association and the American Academy of Pediatrics update recommendations for untrained lay rescuers and trained rescuers resuscitating adults and children who have drowned. Updated guidance reaffirms the recommendation for cardiopulmonary resuscitation (CPR) and highlights the importance of compressions with rescue breaths as a first step in responding to cardiac arrest following drowning

These miniature immune system models -- known as human immune organoids -- mimic the real-life environment where immune cells learn to recognize and attack harmful invaders and respond to vaccines. Not only are these organoids powerful new tools for studying and observing immune function in cancer, their use is likely to accelerate vaccine development, better

A practical calculator predicts the risk of epilepsy after venous stroke. The aim is to improve care for those affected, which are predominantly young adults. A practical calculator that predicts the risk of epilepsy after venous stroke is presented in a study from the University of Gothenburg and others. The aim is to improve care

Glioblastoma is the most common kind of malignant brain tumor in adults. So far, no treatment has been able to make this aggressive tumor permanently disappear. The tumor cells are too varied, and the microenvironment is too tumor-friendly. Researchers have now developed an immunotherapy that not only attacks the tumor -- it also turns its

Researchers have developed a groundbreaking coating that could make medical devices safer for millions of patients, reducing the risks associated with blood clots and dangerous bleeding. The new material is designed to mimic the natural behavior of blood vessels so that catheters, stents, blood-oxygenation machines and dialysis machines won't trigger clotting by activating certain proteins

Researchers are testing a product commonly used to treat ticks and fleas on pets to target fly and mosquito larvae with the goal of helping reduce the spread of diseases carried by these insects.

A research team has succeeded in synthesizing simple, environmentally sensitive cells complete with artificial organelles. For the first time, the researchers have also been able to emulate natural cell-cell communication using these proto-cells -- based on the model of photoreceptors in the eye. This opens up new possibilities for basic research and applications in medicine.

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual pathway, affecting the cell's ability to divide and grow. This opens up new doors to study how the copying of the DNA
