Graphene-coated heart valves could sidestep harmful drugs
Every year thousands of people are fitted with artificial heart valves to replace their own malfunctioning valve. Many of these patients, however, have to remain on drugs that stop blood clotting on these ...
Study reveals secrets of bacterial slime
(Phys.org) —Newcastle University scientists have revealed the mechanism that causes a slime to form, making bacteria hard to shift and resistant to antibiotics.
IBM: Our new gel can kill superbugs
Researchers from computer firm IBM say they have invented a new non-toxic gel that can kill deadly drug-resistant bacteria by cutting through the sludge that shelters them and attacking the germ's cell membrane.
Researchers identify genetic basis of cardiac, craniofacial birth defects
A group of researchers in Israel, the United States and other nations have made important advances in the rapidly-expanding field of "regenerative medicine," outlining for the first time connections in genetic ...
Scientists solve a mystery of bacterial growth and resistance
Scientists at The Scripps Research Institute have unraveled a complex chemical pathway that enables bacteria to form clusters called biofilms. Such improved understanding might eventually aid the development ...

Study backs new heart valve without cracking chest
(AP) -- Thousands of older Americans who need new heart valves but are too frail to survive the surgery might soon get a chance at an easier option - a way to thread in an artificial aortic valve without ...
Bacteria breakthrough is heaven scent
Bacteria are well-known to be the cause of some of the most repugnant smells on earth, but now scientists have revealed this lowest of life forms actually has a sense of smell of its own.
Experimental diet pill shows promise, little risk
(AP) -- An experimental diet pill helped about half the people who tried it lose some weight and keep it off a year later, without the heart problems that some earlier drugs caused, a study found.
Study: Mini clip is safer than heart-valve surgery
(AP) -- Many Americans with leaky heart valves soon might be able to get them fixed without open-heart surgery. A study showed that a tiny clip implanted through an artery was safer and nearly as effective ...
Biodegradable synthetic resin replaces vital body parts
Researchers at the University of Twente (UT) have developed a new type of resin that can be broken down by the body. This new resin makes it possible to replicate important body parts exactly and make them ...
'Beating' heart machine expedites development of new tools for heart surgery (w/Video)
A new machine developed at North Carolina State University makes an animal heart pump much like a live heart after it has been removed from the animal's body, allowing researchers to expedite the development ...
Cutting-edge bacteria research leads to more effective treatment of complex infections
Bacteria are life forms, which, like all other life forms, struggle for the best living conditions for themselves. Therefore they will try to avoid getting attacked by the human immune system, and therefore they have developed ...
Tool-wielding robots crawl in bodies for surgery
Imagine a tiny snake robot crawling through your body, helping a surgeon identify diseases and perform operations.
