Star-shaped metal clip takes novel approach to closing artery punctures
A metal clip that closes an arterial puncture by drawing the wound edges together like a drawstring stitch is proving an easy and effective way to speed patient recovery after coronary interventions. view more (2005-09-12)
Implanted defibrillators: New recommendations for drivers with ICDs
Patients with an Implantable Cardioverter Defibrillator (ICD) have an ongoing risk of sudden incapacitation that might cause harm to others while driving a car. Driving restrictions are imposed making these recommendations an important guideline for patients. view more (2009-06-22)
'Double crystal fusion' could pave the way for portable device
Researchers at Rensselaer Polytechnic Institute have developed a tabletop accelerator that produces nuclear fusion at room temperature, providing confirmation of an earlier experiment conducted at the University of California, Los Angeles (UCLA), while offering substantial improvements over the original design. view more (2006-02-14)
How to save cost for esophageal varices?
Patients with cirrhosis of the liver develop abnormally dilated blood vessels in esophagus. These are called esophageal varices. Blood vomiting may occur from the rupture of these varices, which may be fatal, so it is important to eradicate these varices. view more (2008-05-21)
New device detects heart disease using less than one drop of blood
Testing people for heart disease might be just a finger prick away thanks to a new credit card-sized device created by a team of researchers from Harvard and Northeastern universities in Boston. view more (2009-06-02)
Lending a helping arm
Cambridge engineers develop new system to help disabled peopleA group of engineers at the University of Cambridge has designed a new device to give a ‘helping arm’ to people with muscular weaknesses such as muscular dystrophy or motor neurone disease. The device, which can be attached to the back of a wheelchair, supports the weight of... view more... (2001-05-15)

Northwestern researchers develop bistable nanoswitch
Carbon nanotubes (CNT) have been under intense study by scientists all over the world for more than a decade and are being thought of as ideal building blocks for nanoelectromechanical systems (NEMS). view more (2006-10-16)
Safety device for tall buildings
The device, called `Life-Saver` by the designers, looks like a big badminton shuttlecock. A shock-absorbing cushion connected to two thick torus rings (bagels) covered by a special material, serves as the bean of this shuttlecock. When folded the `Life-Saver` looks like a solid base backpack or a knapsack. When required, a person puts it on the... view more... (2001-12-25)
Quantum ghosts are helpful
The idea that far distant particles can somehow 'talk' to each other worried Einstein so much that he called it 'spooky action at a distance'. view more (2009-04-28)
Device Protects Transplanted Pancreatic Cells from the Immune System
Scientists at Burnham Institute for Medical Research (Burnham) and the University of California San Diego (UC San Diego) School of Medicine have demonstrated in mice that transplanted pancreatic precursor cells are protected from the immune system when encapsulated in polytetrafluorethylene (PTFE). view more (2009-04-10)
