A drug treatment that mimics fasting can also provide the same benefit, study finds CAMBRIDGE, MA — As people age, their intestinal stem cells begin to lose their ability to regenerate. These stem cells are the source for all new intestinal cells, so this decline can make it more difficult to recover from gastrointestinal infections...

New study sheds light on the complex dynamics of Parkinson’s disease
Mark Schnitzer and other Stanford researchers have found the truth is more complicated than a seminal theory of Parkinson’s disease suggested. Credit: L.A. Cicero Parkinson’s disease affects around 10 million people worldwide, yet exactly how the disease and treatments for its symptoms work remains a bit mysterious. Now, Stanford researchers have tested a seminal theory of Parkinson’s and found...

Daily aspirin linked to higher risk in men
Men who take once-daily aspirin have nearly double the risk of melanoma compared to men who are not exposed to daily aspirin, reports a new Northwestern Medicine study. Women, however, do not have an increased risk in this large patient population. “Given the widespread use of aspirin and the potential clinical impact of the link...

Highly elastic biodegradable hydrogel for bioprinting of new tissues
Can generate multiple types of human soft tissues, including skin, skeletal muscles, blood vessels and heart muscles. Researchers at The University of Texas at Arlington have developed a highly elastic biodegradable hydrogel for bio-printing of materials that mimic natural human soft tissues. Bio-printing uses live cells within the scaffolding of the new tissues and could...
