Human vascular system in mice
The formation of new blood vessels, or angiogenesis, is an Achilles' heel of tumor growth, because tumors depend on the supply of oxygen and nutrients for survival. view more (2008-04-15)
Discovery of 'sugar sensor' in intestine could benefit diabetes
Diabetes patients could benefit from new research at the University of Liverpool that has identified a molecule in the intestine that can 'taste' the sugar content of the diet. view more (2007-08-22)
New windows opened on cell-to-cell interactions
Applying biological molecules from cell membranes to the surfaces of artificial materials is opening peepholes on the very basics of cell-to-cell interaction. view more (2009-07-23)
Polarized light pollution leads animals astray
Human-made light sources can alter natural light cycles, causing animals that rely on light cues to make mistakes when moving through their environment. view more (2009-01-07)
Children born after PGD as healthy as those born after conventional IVF treatment
Children born after embryo biopsy for preimplantation genetic diagnosis (PGD) do not show any more major malformations than those born after artificial reproduction technologies (ART) without PGD. view more (2007-06-18)
UCLA chemists create nano valve
UCLA chemists have created the first nano valve that can be opened and closed at will to trap and release molecules. The discovery, federally funded by the National Science Foundation, will be published July 19 in the Proceedings of the National Academy of Sciences. view more (2005-07-18)
Bringing Second Life to life: Researchers create character with reasoning abilities of a child
Today's video games and online virtual worlds give users the freedom to create characters in the digital domain that look and seem more human than ever before. But despite having your hair, your height, and your hazel eyes, your avatar is still little more than just a pretty face. view more (2008-03-11)
The guiding of light: A new metamaterial device steers beams along complex pathways
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard. view more (2009-08-03)
Vanguard I celebrates 50 years in space
The Vanguard I satellite celebrates its 50th birthday this year. Its launch on March 17, 1958 from Cape Canaveral, Florida, culminated the efforts of America's first official space satellite program begun in September 1955. The first solar-powered satellite, Vanguard I has the distinction of being the oldest artificial satellite orbiting the... view more... (2008-03-14)
Bovine tuberculosis in wildlife threatens endangered lynx and cattle health
In an epidemiological survey of Spain's Doñana National Park, the findings of which are published on July 23 in the journal PLoS ONE, Christian Gortázar and colleagues studied the prevalence of bovine tuberculosis (bovine TB) infection among populations of wild boar, red deer and fallow deer in the national park, which is located in... view more...

Soap, DNA and semiconductors
How can studying soap lead to better methods for transporting drugs around the body? Where’s the link between semiconductors and DNA and how can statistical physics reveal how ecosystems evolve? Find out at the Institute of Physics Condensed Matter and Materials Physics (CMMP) Conference being held at the University of Bristol between 18 and... view more... (2000-12-13)
MIT closes in on bionic speed
Robots, both large and micro, can potentially go wherever it's too hot, cold, dangerous, small or remote for people to perform any number of important tasks, from repairing leaking water mains to stitching blood vessels together. view more (2005-11-08)
High-Tech for sausage casings
Sausage is an extremely popular form of meat. Not only Germans each eat an average of 70 grams of sausage every day. To protect the product and keep it "in shape", most sausages are wrapped by an artificial skin, known as the casing. These are frequently made of regenerated cellulose, a synthetic material with entirely natural... view more... (2002-06-07)
Artificial tissue from the test tube
The human body is held together by collagen (from the Greek kolla = glue). This group of structural proteins makes up 20-30 percent of the protein content of mammals - and can be found in skin, cartilage, tendons, ligaments, blood vessels, teeth and bones. The range of associated diseases is correspondingly wide. One example is osteoarthrosis, a... view more... (2003-12-01)
Science, not romance, controls mating at Smithsonian's National Zoo
This Valentine's Day, Cupid won't be making a stop at the Smithsonian's National Zoo. Unlike the spontaneous attraction that most humans equate with love and romance, mating and dating at the National Zoo is planned, strategic and science-based-quite an unromantic encounter. view more (2008-02-11)
MIT engineers probe spiders' polymer art
A team of MIT engineers has identified two key physical processes that lend spider silk its unrivaled strength and durability, bringing closer to reality the long-sought goal of spinning artificial spider silk. view more (2006-10-31)
Corals switch skeleton material as seawater changes
Leopards may not be able to change their spots, but corals can change their skeletons, building them out of different minerals depending on the chemical composition of the seawater around them. view more (2006-07-07)
New biomedical device uses nanotechnology to monitor hip implant healing, may reduce wait times
It is so small, you can barely see it, but a microsensor created by University of Alberta engineers may soon make a huge difference in the lives of people recovering from hip replacement surgery. view more (2006-10-18)
UK researchers aim to create black holes in the lab
Physicists in the UK are planning pioneering experiments to create tiny, artificial black holes in the laboratory which will be able to suck in light or sound waves. The researchers hope that the desk-top black holes will provide important information about the fundamental behaviour of matter and energy and help to resolve some of the apparent... view more...

Artificial intelligence boosts science from Mars
Artificial intelligence (AI) being used at the European Space Operations Centre is giving a powerful boost to ESA's Mars Express as it searches for signs of past or present life on the Red Planet. view more (2008-04-30)
