A multicenter research team led jointly by Washington University School of Medicine in St. Louis and the University of North Carolina at Chapel Hill has received a five-year, $9.5 million grant to further evaluate whether brain imaging can help detect very high risk of autism spectrum disorder in early infancy. […]

Tumors arise when cells shake off their restraints and start to multiply out of control. But how fast a tumor grows does not depend solely on how quickly the cancer cells can divide, a new study has found. By examining brain tumors in mice, researchers at Washington University School of […]

Your heart procedure was a success, and cardiac rehabilitation is going strong. That, of course, is great news. But there’s more to do to keep your mind and body healthy in the long run, says Susan Ryskamp, a dietitian at the University of Michigan Frankel Cardiovascular Center. One key factor: food. […]

DNA assembled into nanostructures such as tubes and origami-inspired shapes could someday find applications ranging from DNA computers to nanomedicine. However, these intriguing structures don’t persist long in biological environments because of enzymes called nucleases that degrade DNA. Now, researchers have designed DNA nanostructures that can heal themselves in serum. […]

Are some flavors of vape liquid more harmful than others? A UA scientist says yes, based on the results of a novel research project that used stem cells to study the effects of vaping on endothelial cells. Your favorite vape flavor may be more harmful than the nicotine itself. Using […]

Unregulated cell division is a hallmark of cancer, and one of the key proteins involved in controlling cell division is called FoxM1. Abnormal activation of FoxM1 is a common feature of cancer cells and is correlated with poor prognosis, metastasis, and resistance to chemotherapy. Now researchers at UC Santa Cruz […]

Researchers at the University of Cambridge have uncovered a specialised population of skin cells that coordinate tail regeneration in frogs. These ‘Regeneration-Organizing Cells’ help to explain one of the great mysteries of nature and may offer clues about how this ability might be achieved in mammalian tissues. It has long […]

Mitochondria, the ‘batteries’ that produce our energy, interact with the cell’s nucleus in subtle ways previously unseen in humans, according to research published in the journal Science. The study, led by scientists at the University of Cambridge, suggests that matching mitochondrial DNA to nuclear DNA could be important when selecting […]

Researchers report that a protein known to be important to protein synthesis also influences muscle regeneration and regrowth in an unexpected manner. The discovery, reported in the Journal of Clinical Investigation, could one day lead to new methods for treating disorders that result in muscle weakness and loss of muscle […]

Your body’s cellular structure is programmable, making it possible for it to be changed into other kinds of cells. And today, already a number of scientific studies have found at least a couple of ways to reprogram certain types of human cells. Using these methods, the body can potentially become […]

Pain is an unpleasant sensation that is part of the body’s protective mechanism designed to give a warning of potential or actual tissue damage. When pain is not managed effectively, it can persist and become debilitating, resulting in an overwhelming burden of suffering and poor quality of life. Due to […]

The immune system is programmed to rid the body of biological bad guys—like viruses and dangerous bacteria—but its precision isn’t guaranteed. In the tens of millions of Americans suffering from autoimmune diseases, the system mistakes normal cells for malicious invaders, prompting the body to engage in self-destructive behavior. This diverse […]
