Chronic dysentery was likely not the killer of Edward the Black Prince, despite what is commonly believed
Whatever disease killed Edward the Black Prince—heir apparent to the English throne in the mid 1300s, and heralded as the greatest English soldier ever to have lived—is unlikely to have been chronic dysentery, as is commonly believed, writes a mi.....»»
A robust self-healing polymer made from a common chemical
Material scientists at RIKEN have created a self-healing polymer by using an off-the-shelf compound for the first time. The strategy they used is promising for improving the durability and minimizing the environmental impact of various commercial pol.....»»
Pollination loss removes healthy foods from global diets, increases chronic diseases causing excess deaths
Inadequate pollination has led to a 3-5% loss of fruit, vegetable, and nut production and an estimated 427,000 excess deaths annually from lost healthy food consumption and associated diseases, including heart disease, stroke, diabetes, and certain c.....»»

Parallel alignment of dressing fibers accelerates wound healing
A team of researchers from Singapore has reported the development of a skin-mimicking scaffold by parallelly aligning nanofibers made up of a mixture of polycaprolactone (PCL) and gelatin that enhances wound healing. Their research has recently been.....»»
Lights, hurricane, action: Preparing for and enduring big storms
Hurricane damages cost an average of $20.5 billion per event in the United States. Their effects are widespread and often chronic, with loss of infrastructure, communities, and lives. The aftershocks ripple out farther still—pressure is mounting on.....»»
How heart failure disrupts the cell"s mitochondria
Chronic heart failure causes the cell's powerhouses to malfunction, in part due to overconsumption of an important intermediary compound in energy production. Supplementing the diet to compensate for this could prove a promising strategy for treating.....»»
How do fishes scratch their itches? It turns out sharks are involved
