Astronaut John Glenn, 92, has heart procedure
Former astronaut and Ohio U.S. senator John Glenn has had a heart valve replacement as he approaches his 93rd birthday.
Ion beams pave way to new kinds of valves for use in spintronics
Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have tested a new approach to fabricating spin valves. Using ion beams, the researchers have succeeded in structuring an iron aluminium alloy ...
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 ...
Inflatable antennae could give CubeSats greater reach
The future of satellite technology is getting small—about the size of a shoebox, to be exact. These so-called "CubeSats," and other small satellites, are making space exploration cheaper and more accessible: ...
Silver coating kills bacteria on campus door handles
Can a door handle keep you healthy? That depends on what's on it. Most are teeming with bacteria: staph, E. coli, Enterococcus and sometimes even Salmonella. That stuff can make you sick.
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 ...
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.
Rotary valve could help propel craft to Mars one day
(Phys.org) —A rotary fuel delivery valve developed by a UAHuntsville team led by Dr. James Blackmon just might help us get manned space flights out of our immediate neighborhood one day, and he says it ...
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.
Drug improves quality of life for Dobermanns with heart disease
Veterinary scientists at the University of Liverpool have found that early screening and drug treatment for Dobermann dogs with a serious heart disease can extend and improve their quality of life.
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 ...
'Spintronic' LED invented: New technology promises brighter TV, computer displays
University of Utah physicists invented a new "spintronic" organic light-emitting diode or OLED that promises to be brighter, cheaper and more environmentally friendly than the kinds of LEDs now used in television ...
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.
SpaceX private rocket blasts off for space station (Update)
A first-of-its-kind commercial supply ship rocketed toward the International Space Station following a successful liftoff early Tuesday, opening a new era of dollar-driven spaceflight.
