A new type of wound dressing made of silica gel fibers will soon help to heal difficult wounds caused by burns or diabetes. The dressing forms a supporting matrix for newly growing skin cells and is fully absorbed by the body during the healing process.
Synthetic Copycat Of Living Cell Underway: Life, But Not As We Know It?

Researchers have taken some important first steps to creating a synthetic copycat of a living cell. Scientists have used polymers -- long-chain molecules -- to construct capsule-like structures that have properties mimicking the surfaces of a real cell. They show how in the laboratory they have been able to encourage the capsules to 'talk' to natural bacteria cells and transfer molecular information.

Patients in developing countries often need to have X-ray examinations repeated so that doctors have the image quality they need for useful medical diagnosis, the IAEA is learning. The findings come from a survey involving thousands of patients in 45 hospitals and 12 countries of Africa, Asia and Eastern Europe.
Expansion Of High Tech Materials

Industrial applications are ever more frequently demanding materials of highest thermal stability. A precision interferometer has been developed to exactly measure this property. With this instrument, the change in length can be determined with highest accuracy in an absolute measurement as a function of temperature, time and -- if necessary -- ambient pressure.
Spectral Emissivity Measurements For Radiation Thermometry

Industry and research are increasingly relying on non-contact temperature measurements with the aid of heat radiation, for example, for the reliable and reproducible drying of car paint. In order to attain exact and reliable results, the emissivity of the measured surface has to be known. It can only be determined precisely in complex measuring facilities. Now researchers have developed a modern emissivity measuring facility for industry-oriented calibrations.

Good soldiers never pass up a chance to eat or sleep. They never know how much they'll be called on to do before the next chance.
Without tenderness, a man is uninteresting.
The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration.
