River-shelf interactions during Spring floods in the coastal Beaufort Sea
Multi-year study provides insights to possible future responses to environmental change in the arctic. view more (2006-12-06)
Horphag's Prelox provides over-the-counter solution
For couples worldwide, erectile dysfunction (ED) is one of the leading contributors to a man's inability to perform. As millions of men in America each year look for a solution, many seek alternative treatments to prescription medications and surgery that may have dangerous side effects. view more (2007-12-04)
Debate focuses on door-to-balloon time in heart attack treatment
In the treatment of heart attack, the 90-minute goal for inflation of an angioplasty balloon in a blocked coronary artery to restore normal blood flow is so revered it's been codified in clinical guidelines, accreditation standards, and pay-for-performance programs. view more (2007-05-14)
Just 30 minutes exercise a day could reduce deaths from heart disease
Currently around one in five menopausal women die from heart disease. But according to new research by exercise scientists at Liverpool John Moores University (LJMU), this shocking statistic could be reversed if women took just 30 minutes exercise, five days a week. The findings are based on the initial results of a 12-month study of 24... view more... (2005-01-31)
Hospitals could reduce unnecessary tests for cardiac diagnostic imaging
Hospitals that perform cardiac nuclear stress testing under published national practice guidelines could reduce unnecessary testing and, potentially costs, according to a Henry Ford Hospital study. view more (2008-09-15)
New design for transistors powered by single electrons
Scientists have demonstrated the first reproducible, controllable silicon transistors that are turned on and off by the motion of individual electrons. view more (2006-02-03)
Carbon nanotube membranes allow super-fast fluid flow
Membranes composed of manmade carbon nanotubes permit a fluid flow nearly 10,000 to 100,000 times faster than conventional fluid flow theory would predict because of the nanotubes' nearly friction-free surface. view more (2005-11-04)
Novel Non-Invasive Imaging Technology May Allow Precise Diagnosis of Coronary Artery Disease, Treatment Tailoring
A study focusing on a new non-invasive imaging technology—one that may enable more precise diagnosis of coronary artery disease and treatment tailoring in individual patients—was released by Israeli researchers at SNM's 53rd Annual Meeting June 3—7 in San Diego. view more (2006-06-08)
Scientists develop 'cyborg engineering' for coronary bypass grafting
A team of London scientists have taken a major step in making the use of artificial veins and arteries in coronary bypass grafts a reality. view more (2008-06-04)
Penn study points to how COX-2 inhibitors can eventually lead to heart disease
University of Pennsylvania School of Medicine researchers have found additional evidence that may help explain how selective inhibitors of COX-2 might predispose individuals to heart disease and stroke. view more (2005-05-25)
Videos extract mechanical properties of liquid-gel interfaces
Blood coursing through vessels, lubricated cartilage sliding against joints, ink jets splashing on paper-living and nonliving things abound with fluids meeting solids. view more (2008-01-24)
Statistical tool could explain gene study variations
While scientists are using the human genome to associate certain genes with disease, Dr. Hongyan Xu wants to ensure they are accounting for natural variations in those genes. view more (2008-05-29)
New method for testing condition of seeds
Wageningen UR develops method for testing condition of seeds Flow-cytometry, the technique for studying large numbers of individual cells in a fluid, can be combined with the use of special fluorescent colouring agents to form a valuable method of determining the health of seeds and seed consignments. This is shown in the thesis with which... view more... (2001-04-03)
Nottingham project to improve treatment for patients with incurable blood disease
The new Sickle Cell Anaemia Detector research project, being launched today by MP Paul Boateng, has been funded with a £237,000 grant from the Big Lottery Fund - £112,000 of which will be coming to Nottingham - and involves partners at Imperial College and the Sickle Cell Society. view more (2005-04-01)
Cause of diabetes-related erectile dysfunction is clarified by Johns Hopkins researchers
A new study from the Brady Urological Institute at Johns Hopkins suggests an over-supply of a simple blood sugar could be a major cause of erectile dysfunction in diabetic men. view more (2005-08-10)
Drug compound restores youth to aging arterial cells in elderly hypertensives, Hopkins study shows
A compound called alagebrium, which is very similar to another used in anti-wrinkle creams, may be useful in reducing the deleterious effects of arterial aging in the majority of elderly Americans with systolic hypertension. view more (2005-11-16)
NIST announces first observation of 'persistent flow' in a gas
Using laser light to stir an ultracold gas of atoms, researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have demonstrated the first "persistent" current in an ultracold atomic gas -a frictionless flow of particles. view more (2007-11-28)
'Rotten eggs' in the blood
Hydrogen sulphide (H2S) is a gas most commonly associated with the smell of stink bombs, sewage and rotten eggs, but a team of researchers from the Peninsula Medical School in the South West of England and King's College London have now identified a role for this gas in regulating blood pressure, according to research published today in the... view more...

Could this be the end for injections?
Nightmares of doctors or dentists with oversized hypodermic needles could soon be a thing of the past. A new painless way of delivering drugs through the skin is described in the journal BMC Medicine this week - and needles are not involved. The technique, called microscission, uses a stream of gas to bombard small areas of the skin with tiny... view more... (2004-04-14)
Flight of the bumble (and honey) bee
Insects such as honeybees and bumble bees are predictable in the way they move among flowers, typically moving directly from one flower to an adjacent cluster of flowers in the same row of plants. view more (2009-03-23)
