These days our supermarket shelves are filled with more and more so-called “functional foods” foods with special health-promoting properties. These products often represent a “high-tech” product line, in the twilight zone between food and medicine. Agricultural researcher Cecilia Mark-Herbert from the Swedish University of Agricultural Sciences, SLU, has now studied the market for these products. Her doctoral dissertation shows that developing these foods requires not only new products, but also new
Several years ago an “electronic nose” was developed at Linköping University in Sweden. It was based on a number of different gas sensors and programmed to differentiate between various substances in air. This nose is now being joined by a corresponding sensor for fluids, the “electronic tongue.” The principle behind the “electronic tongue” is that a number of electrodes are submerged in the fluid. When a current is turned on across the electrodes the response varies depending on the liquid’s content
Nuclear tests up gene mutation risk.
People in the remote former Soviet republic of Kazakhstan who were exposed to fallout from nuclear-weapon tests have more genetic mutations in their eggs and sperm than normal, researchers have found 1 . Their children could inherit health defects caused by such mutations.
The Soviet Union detonated 470 nuclear weapons at the Semipalatinsk nuclear-testing site between 1949 and 1989, many above ground. The blasts showered r
The next generation of biomaterials will help the body heal itself by prompting cells to repair their own tissues, scientists report today.
Writing in a review in the journal Science, Professors Larry Hench and Julia Polak of Imperial College, London, highlight the potential of `third generation` biomaterials that activate specific cells and genes of the individual they are implanted into.
Pioneering work by the two authors recently led to the discovery of a family of bone f
GENOPIA Biomedical LLC (GENOPIA), a biotechnology firm headquartered in Saarbücken, Germany and Ciphergen Biosystems, Inc. (Nasdaq: CIPH) in Fremont, CA, will collaborate on the discovery and the development of new drug targets and candidates for CNS diseases. GENOPIA Biomedical focuses on the development of novel drug candidates and uses advanced proteomics as its main drug discovery and high-throughput screening tool, while Ciphergen Biosystems is a world leader in the development of proteomics te
Climate prediction just got trickier, according to two new studies appearing in the current issue of the journal Science. Analysis of more than two decades of satellite data shows that more sunlight entered the tropics and more heat escaped to space in the 1990s than a decade earlier. Moreover, current climate models fail to account for the new findings, suggesting that they may contain more uncertainty than previously thought.
For the earth’s climate to remain unchanged, the planet’s ener
