A novel sensor designed by MIT researchers could dramatically accelerate the process of diagnosing sepsis, a leading cause of death in U.S. hospitals that kills nearly 250,000 patients annually. Sepsis occurs when the body’s immune response to infection triggers an inflammation chain reaction throughout the body, causing high heart rate, high fever, shortness of breath… Read more

Catechol, an adhesive found in mussel proteins, shows promise for smart glues – a small jolt of electricity can turn the stickiness on and off – but that’s not its only potential use, a team of engineers discovered. In microgel form, it reduces the ability of bacteria and virus to infect by at least 99… Read more

An alternate pathway that Listeria uses to enter the bloodstream has been discovered by Purdue University scientists. The finding suggests that forms of the foodborne bacteria considered benign may be more dangerous than once thought. About 600 million people around the world contract listeriosis each year, with 420,000 dying, according to the World Health Organization… Read more

Researchers in China have recently developed a new wound dressing that has the ability to improve the healing of open wounds. The group developed the dressing using an extract from konjac, a plant native to eastern Asia, and incorporated silver nanoparticles within it. When tested in rabbits, the researchers found that the dressing accelerated healing… Read more

How can immune cells remember an infection or a vaccination so that they can spring into action decades later? Scientists at the University of California, Berkeley, in collaboration with investigators at Emory University, have found that a small pool of the same immune cells that responded to the original invasion remain alive for years, developing… Read more
