Snow made from potatoes
Films set in snow-laden winter landscapes cannot always be produced in the dead of winter. Until now, expensive artificial snow had to be imported from Hollywood to obtain the desired effects. In addition, it is always a laborious task to remove the splendid white chips made from polyethylene film after the shooting is over - almost unavoidable... view more... (2002-12-20)
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)
Measuring and modeling blood flow in malaria
When people have malaria, they are infected with Plasmodium parasites, which enter the body from the saliva of a mosquito, infect cells in the liver, and then spread to red blood cells. view more (2009-11-23)
Modern nerve stimulators to kill pain
Managing pain may one day be as easy as sticking on a Band-AidTM. Russian researchers at the company BIOFIL Ltd. in Sarov are developing a line of miniature transcutaneous electrical nerve stimulation (TENS) devices that work as a non-drug alternative to pain relief and are small enough for patients to use without hindering daily life. TENS... view more... (2003-11-13)
Fishing in the dark
Nanotechnology is a relatively new scientific field that holds immense promise for the future. A nanometer is one millionth of a millimeter, and nanoparticles form the basis of completely new materials for pharmaceutical, cosmetic, electronic and optical applications. The size and structure of the particles are decisive in regulating the optical,... view more... (1999-09-03)
Unique nerve-stimulation device proves effective against epilepsy
Epilepsy is a common medical condition characterized by convulsions and short periods of confusion. It affects more than 50 million people worldwide. But intractable epilepsy, which affects more than 1 million Americans and is often resistant to drug treatment and surgery, is arguably worse. view more (2009-03-19)

UC Davis researchers identify a protein that may help breast cancer spread, beat cancer drugs
New research from UC Davis Cancer Center shows that a protein called Muc4 may be the essential ingredient that allows breast cancer to spread to other organs and resist therapeutic treatment. view more (2009-04-02)
Spacecraft, heal thyself
Building spacecraft is a tough job. They are precision pieces of engineering that have to survive in the airless environment of space, where temperatures can swing from hundreds of degrees Celsius to hundreds of degree below zero in moments. view more (2006-01-23)
Blood testing, mosquito style
A skin patch could one day provide a less-invasive alternative for diabetics who need to take regular samples of their own blood to keep glucose levels in check. The common method of drawing blood from fingertips and using glucose testing strips and metres can be painful, inconvenient and time-consuming. view more (2009-04-24)
Why passive smoking hinders healing
Being exposed to high levels of 'second-hand' smoke can reduce the speed at which wounds heal, leading to a lack of healing or greater levels of scarring. A study published in the journal BMC Cell Biology this week may begin to explain why: when cells are exposed to smoke, their ability to migrate towards the site of damage is compromised. The... view more... (2004-04-01)
New method separates cancer cells from normal cells
The vast majority of cancer deaths are due to metastasis, the spread of cancer cells from its primary site to other parts of the body. view more (2009-06-16)
