Black-footed ferrets sired by males that died 8 years ago
Two black-footed ferrets at the Smithsonian's National Zoo have each given birth to a kit that was sired by males who died in 1999 and 2000 view more (2008-09-03)
Prince Philip Medal for Engineer who Pioneered Synthetic Bone
Professor William Bonfield CBE, FREng, FRS, Professor of Medical materials at the University of Cambridge, has won this year's prestigious Royal Academy of Engineering's Prince Philip Medal. HRH Prince Philip, Duke of Edinburgh, as The Academy's Senior Fellow, will present Professor Bonfield with the solid gold medal at the Academy Awards Dinner... view more... (2004-06-10)
A New Way to Assemble Cells into 3-D Microtissues
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory can now control how cells connect with one another in vitro and assemble themselves into three-dimensional, multicellular microtissues. The researchers demonstrated their method by constructing a tailor-made artificial cell-signaling system, analogous to natural... view more... (2009-03-06)
Fewer heart patients need antibiotics before dental procedures
Based on a review of new and existing scientific evidence, most dental patients with heart disease do not need antibiotics before dental procedures to prevent infective endocarditis (IE), a rare, but life-threatening heart infection. view more (2007-04-20)
Model unravels rules that govern how genes are switched on and off
For years, scientists have struggled to decipher the genetic instruction book that details where and when the 20,000 genes in a human cell will be turned on or off. Different genes operate in each cell type at different times, and this careful orchestration is what ultimately distinguishes a brain cell from a liver or skin cell. view more (2008-12-05)
Romance, schmomance - Natural selection continues even after sex
Some breaking news, just in time for Valentine's Day: Researchers have identified something called 'sperm competition' that they think has evolved to ensure a genetic future. In sexual reproduction, natural selection is generally thought of as something that happens prior to - and in fact leads to - the Big Event. view more (2007-02-13)
Endless original, copyright-free music
UGR researchers Miguel Delgado, Waldo Fajardo and Miguel Molina decided to design a software programme that would enable a person who knew nothing about composition to create music. view more (2009-06-02)
From the surface of Mars to the skin on your body: UK science goes public
The 24 exhibits cover an extraordinary range of up-to-the-minute research. A model of the Beagle 2 robot lander - that will range over the Martian surface - is on show, as is a 3-D tour of an astronomical observatory in Hawaii. There is a novel look deep inside turbulent industrial processes; a chance to test your skills as a surgeon under the... view more... (1999-06-04)
New Tissueflex System Makes Artificial Liver Cell Cultivation an Attractive and Viable Option
The drug development process from the discovery of an optimised lead then on to market is typically a seven to ten year process. It is well known to be an expensive process with a high risk of failure as recent high profile cases have shown. But even after extensive clinical trials new drugs can prove to be ineffective or at worst dangerous to... view more... (2004-11-19)
Singing to females makes male birds' brains happy
The melodious singing of birds has been long appreciated by humans, and has often been thought to reflect a particularly positive emotional state of the singer. view more (2008-10-03)
Phoning home quietly could net sound engineers £50,000
Telling the whole carriage which train you're on could be a thing of the past thanks to new 3D audio technology targeted for incorporation into the next generation of mobile phones. The engineers who may have saved travellers from each other's small talk are now in line for Britain's biggest engineering prize, the Royal Academy of Engineering... view more... (2001-07-03)
3-D ultrasound scanner could guide robotic surgeries
Duke University engineers have shown that a three-dimensional ultrasound scanner they developed can successfully guide a surgical robot. view more (2006-10-31)
A model of Pancreas based on the insulin extracting gel-polymer system
If the blood glucose overcontents (permissible content is 0.8-1 mg/ml), the pancreas be-gins to extract some inculin by which an unnecessary glucose is eliminated from blood and is assimilated by tissues. view more (1999-08-20)
Mechanical 'artificial hearts' can remove need for heart transplant by returning heart to normal
Mechanical 'artificial hearts' can be used to return severely failing hearts to their normal function, potentially removing the need for heart transplantation, according to new research. view more (2006-11-02)
Scientists discover who is likely to get dry eye syndrome after LASIK surgery
Scientists at Schepens Eye Research Institute have found that people with a certain low level of tear production are more likely to develop chronic dry eye syndrome after LASIK (laser-assisted in situ keratomileusis), laser refractive surgery to correct near- and far-sightedness than those with more plentiful tears. view more (2008-03-04)
A step toward tissue-engineered heart structures for children
Infants and children receiving artificial heart-valve replacements face several repeat operations as they grow, since the replacements become too small and must be traded for bigger ones. Researchers at Children's Hospital Boston have now developed a solution: living, growing valves created in the lab from a patient's own cells. view more (2007-09-13)
Image processing for applications in artificial vision
For a robot to identify objects in a particular image, it is first necessary that it can "see" them. With this aim, in artificial vision, edge detectors are normally used, i.e. computer programmes that delimit the objects in an image and define the limits between them and the background, and between the different objects themselves. view more (2006-01-17)
Light pollution offers new global measure of coral reef health
We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl. view more (2008-11-25)
A new approach to growing heart muscle
It looks, contracts and responds almost like natural heart muscle - even though it was grown in the lab. And it brings scientists another step closer to the goal of creating replacement parts for damaged human hearts, or eventually growing an entirely new heart from just a spoonful of loose heart cells. view more (2006-12-08)
Electronic chip, interacting with the brain, modifies pathways for controlling movement
Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement. view more (2006-10-25)
