Space Debris: Who takes the rubbish down?
The expanses of space may be indefinite, but 800 kilometres above the Earth's surface an acute waste problem exists already today: hundreds of thousands of bits of scrap constitute a massive threat to satellites and space stations. Are we in danger of impending failure of communication, television and navigation satellites? A laser developed at DLR could help to solve the problem.
Cancer Diagnostics: Fruit Flies as Cancer Sensors
If one blows the evaporations from cancer cells and, respectively, healthy cells onto the olfactory antennae of fruit flies, very different stimulation patterns can be observed. Researchers intend to use these insights for developing a sensor for application in cancer diagnostics.
Nanotechnology: A Laboratory in a Water Droplet
They can be found in ketchup and cosmetics: nanoparticles. A discovery from the kitchen could help to make their production more environmentally friendly.
Cancer Statistics: "We still know too little"
Also in Germany, surviving cancer is dependent on the social and economic conditions at the place where people live. We spoke to Lina Jansen from the German Cancer Research Center (DKFZ) about potential reasons and the prognosticated worldwide increase of cancer cases in the coming years.
Scientific Careers: Good reasons for Germany
It is still considered an advantage - and in some cases even an absolute prerequisite - for researchers to launch their career in the United States and work hard there to develop an excellent reputation.
