T-cells are an important component of our immune system: with the receptors they carry on their surface, they can recognize highly specific antigens. Upon detection of an intruder, an immune response is triggered. It is still ...

Laser beams can be used to precisely measure an object's position or velocity. Normally, however, a clear, unobstructed view of this object is required—and this prerequisite is not always satisfied. In biomedicine, for ...

Of course, there is no weather in our sense of the word in space—nevertheless, soil can also "weather" in the vacuum of space if it is constantly bombarded by high-energy particles, such as those emitted by the sun. The ...

Ordinary solid-state lasers, as used in laser pointers, generate light in the visible range. For many applications, however, such as the detection of molecules, radiation in the mid-infrared range is needed. Such infrared ...
