A new use of old technology could lead to handheld scanning diagnostic devices (as seen in Star Trek!) one day becoming a reality.
Writing in the October issue of Biologist, Steve Mitchell and colleagues (Imperial College of Science Technology and Medicine, London) envisage a future where, ‘an entire individual could be quickly scanned using a handheld device. Extrapolating further, such a scan could provide a virtually instant readout of an individual’s biochemistry, revealing potential illnesses and providing a diagnosis, even before the emergence of any clinical manifestations.’
A new application of existing technology offers a first step in understanding the human genome in action, whereby we can follow change inside cells without a complete understanding of what these changes involve. Nuclear magnetic resonance spectroscopy (originally discovered in 1945, but since made both more specific and much more sensitive) can analyse the molecular contents of a cell – producing distinct patterns, which promise to reliably indicate different disease processes. By following patterns, rather than individual proteins, scientists gain an overview of entire cell processes, and a valuable insight into the nature of cellular change.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
