Scientists create first working model of a 2-qubit electronic quantum processor
A team led by Yale University researchers has successfully implemented simple algorithms using a quantum processor based on microwave solid-state technology--similar to that found in computers and cell phones. view more (2009-07-01)
Small molecules mimic natural gene regulators
In the quest for new approaches to treating and preventing disease, one appealing route involves turning genes on or off at will, directly intervening in ailments such as cancer and diabetes, which result when genes fail to turn on and off as they should. view more (2009-06-04)
Media invitation: Why everyone should be a cyborg
It's every technophobe's nightmare and the stuff of all the Terminator movies but Professor Kevin Warwick has always wanted to become the world's very first cyborg. And now he wants everyone else to join him! Not content with being able to control an electric wheelchair and an intelligent artificial hand (using a one hundred electrode array which... view more...

Coming soon: Cell therapies for diabetes, cancer?
Therapies using stem cell transplants are advancing promising treatments for such conditions as Alzheimer's Disease, neurological diseases and spinal cord injury, and heart disease. view more (2008-03-20)
Phytochemicals may protect cartilage, prevent pain in joints
Johns Hopkins researchers have discovered that plant-derived compounds known for their ability to protect tissue also appear to block the activity of an enzyme that triggers inflammation in joints. view more (2005-10-04)
Flowers shape themselves to guide their pollinators to the pollen
Why do flowers specialize on different pollinators? For example, both bats and hummingbirds pollinate plants in tropical forests; why adapt to just one instead of using both? Biologists often assume that tradeoffs contribute to such specialization (the jack of all pollinators is master of none), yet surprisingly little evidence exists in support... view more...

Ants more rational than humans
In a study released online on July 22 in the journal Proceedings of the Royal Society: Biological Sciences, researchers at Arizona State University and Princeton University show that ants can accomplish a task more rationally than our - multimodal, egg-headed, tool-using, bipedal, opposing-thumbed - selves. view more (2009-07-27)
The cost of long tongues
Orchid bees use their extraordinarily long tongues to drink nectar from the deep, tropical flowers only they can access. view more (2007-04-17)
UPMC begins study of heart support device as a bridge to transplantation
Doctors at UPMC have begun a study using an investigational cardiac device, the VentrAssist™ Left Ventricular Assist System (LVAD) to see whether it can be used safely and effectively in patients with end-stage heart failure. view more (2007-05-22)
Constant compressions critical to CPR
Interrupting chest compressions during resuscitation reduces the chances of heartbeat return after defibrillation. New research published in the open access journal BMC Medicine shows that for every second of a pause in compressions there is a 1% reduction in the likelihood of success. view more (2009-02-06)
"Ear ear" - a new audio world at the Science Museum
·How do you know instinctively where to look for a plane when it passes over? ·Where is that fly when you want to swat it? ·What has this got to do with Microsoft's new X-box games console? Hearing in three dimensions is the focus of a new display opening tomorrow, Wednesday 14 November, at the Science Museum in London. The display, called Audio... view more... (2001-11-13)
Seawater intrusion is the first cause of contamination of coastal aquifers
Seawater intrusion is often the consequence of freshwater aquifers overexploitation. This is a very common and serious phenomenon all over the Mediterranean basin, as well as in other areas with similar weather conditions and population. view more (2007-07-30)
Extreme weather postpones the flowering time of plants
Extreme weather events have a greater effect on flora than previously presumed. A one-month drought postpones the time of flowering of grassland and heathland plants in Central Europe by an average of 4 days. view more (2008-11-06)
An Antimicrobial Solution For Blocked Urinary Catheters? (p 1435)
Authors of a research letter in this week's issue of THE LANCET propose a new method for inflating urinary catheters-which could avoid common problems of encrustration and blockage of the catheter. Urinary catheters are usually inflated with water, but this often results in bacterial build-up leading to catheter encrustration and blockage. David... view more... (2003-04-23)
Nature Points the way to a sustainable hydrogen economy
"This is an exciting early step in developing a sustainable system for producing electricity from hydrogen" said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). "In Nature iron-sulphur enzymes catalyse a range of important chemical reactions that industry can only do by using precious metal... view more... (2005-02-10)
Brain measurements could lead to better devices to move injured or artificial limbs
Neuroscientists at the Hebrew University of Jerusalem have developed a novel approach for measuring and deciphering brain activity that holds out promise of providing improved movements of natural or artificial limbs by those who have been injured or paralyzed. view more (2007-10-19)
Finely tuned laser strikes the right chord
Pulses of laser light can make molecules react in ways that are impossible using classical test-tube chemistry. Molecules vibrate, and each molecule has its own "tone," its own "melody." It's a question of finding the right key, and that is something that a "smart" laser beam can do. It can find its way to the... view more... (2002-05-30)
Gorilla regains sight in ground-breaking operation by Bristol Zoo Gardens
Romina, a female Western lowland gorilla at Bristol Zoo Gardens, has successfully undergone pioneering surgery to restore her sight in the first ever cataract operation performed in Europe on an adult gorilla. Born with cataracts, 21-year-old Romina underwent the two-hour procedure at the University of Bristol`s Veterinary Hospital in March and,... view more... (2002-04-11)
Chemistry & Industry- Issue 3
FEATURES TERROR: Future Threats Hype about bioterrorism may not be so far-fetched, Marina Murphy reports (page 9) Despite their best efforts, terrorists have not been able to cause the widespread havoc that they would like. Today, bio-terrorists are limited by technology, but in the future, this will not be the case. Advances in genomics mean... view more... (2003-01-29)
Researcher says microchannels could advance tissue engineering methods
Utilizing fractal patterns similar to those created by lightning strikes, Victor Ugaz, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, has created a network of microchannels that could advance the field of tissue engineering by serving as a three-dimensional vasculature for the support of... view more...
