Physicists render usable method for detecting extremely rare inert gas isotopes for water dating

17-10-2014

In the earth and environmental sciences, radioactive isotopes, atom variants that decay over time, play a major role in age determination. A radioactive isotope of the inert gas argon (39Ar), for example, is used to determine the age of water or ice. Such isotopes are extremely rare, however – ...

Slow-motion movies of tiny nanostructures

Researchers developed a novel microscope

07-10-2014

Physicists from the University of Regensburg have developed a novel microscope that allows them to record slow-motion movies of tiny nanostructures with groundbreaking time resolution – faster even than a single oscillation cycle of light. With their new microscope they have directly imaged the ...

Sensor network tracks down illegal bomb-making

06-10-2014

A network of different sensors is to detect illicit production of explosives and improvised explosive devices (IEDs). Traces on doorknobs, in sewage or in the air will be detected by the sensors and the data will be fused in a command center. The Fraunhofer Institute for Applied Solid State ...

“Multi-spectra glasses” for scanning electron microscopy

30-09-2014

The scanning electron microscope is not only used for precisely surveying the surface topology of samples, but also for determining their chemical compositions. This is done by exciting the atoms to fluoresce under irradiation by an electron beam while scanning the sample. This secondary emission ...

Water movement as detection aid for molecules

26-09-2014

Water is a ubiquitous solvent in all life sciences – sometimes referred to as the "matrix of life". Contrary to earlier assumptions, it is not a passive witness of biochemical processes; rather, it participates in them actively. By influencing the movement of water molecules surrounding their ...

A New Strategy to Analyze The Cellular World

Scientists develop new tool to analyze cellular structures via high- resolution imaging

25-09-2014

In the past two decades, super-resolution microscopy has been one of the fastest evolving fields through many technical improvements. However, the development of new labeling tools, probes and their biological application, is mostly lagging behind the technical capabilities. Most recently, Prof. ...
