The catalysts are composed of a unique structure of single gold atoms bound by oxygen to several sodium or potassium atoms and supported on non-reactive silica…

Applied to the outer shell of the payload section of a rocket using pipettes, small, double-stranded DNA molecules flew into space from Earth and back again….

Red mites are the most common ectoparasites of poultry and cause substantial economic damage worldwide. Scientists at the University of Hohenheim have developed a method to combat red mites which utilizes the fact that the mites are sensitive to heat and that the parasite only visits the host at night for feeding and then hides in dark spaces near the host. The method presents hollow, perforated perches as appropriate hiding places where mites in all states of development are killed through thermal treatment. Because of the purely mechanical nature of the process there is no health risk for personnel. Since temperature and speed of the heating device are regulated by a PLC (programmable logic controller), farm workers are free to carry out other tasks while the treatment takes place.

The invention presented here is a temperature-compensated FBG measurement system based on interferometry. It is characterized by naturally high sensitivity and high dynamic range well in excess of a period of interference. The system makes do with commercially available and cheap components that can be easily combined and implemented.

The inventors here present a novel, highly specialized plasma membrane protein responsible for citrate uptake in cancer cells. This transporter with its function of citrate import is a specific marker for cancer cells and offers therefore a promising target for diagnostic and therapeutic approaches.
