Enhanced NMR reveals chemical structures in a fraction of the time
MIT researchers have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy (NMR), a technique used to study the structure and composition of many kinds of molecules, including proteins linked to Alzheimer's and other diseases. Using this new method, scientists should be able to analyze in mere minutes structures that would previously have taken years to decipher, says Robert Griffin, the…
Smart microrobots that can adapt to their surroundings
One day we may be able to ingest tiny robots that deliver drugs directly to diseased tissue, thanks to research being carried out at EPFL and ETH Zurich. The group of scientists -- led by Selman Sakar at EPFL and Bradley Nelson at ETH Zurich -- drew inspiration from bacteria to design smart, biocompatible microrobots that are highly flexible. Because these devices are able to…
How molecules teeter in a laser field
When molecules interact with the oscillating field of a laser, an instantaneous, time-dependent dipole is induced. This very general effect underlies diverse physical phenomena such as optical tweezers, for which Arthur Ashkin received the Nobel Prize in Physics in 2018, as well as the spatial alignment of molecules by a laser field. Now scientists from the Max Born Institute for Nonlinear Optics and Short Pulse…
Complex molecules emerge without evolution or design
In biology, folded proteins are responsible for most advanced functions. These complex proteins are the result of evolution or design by scientists. Now, a team of scientists led by University of Groningen Professor of Systems Chemistry, Sijbren Otto, have discovered a new class of complex folding molecules that emerge spontaneously from simple building blocks. The results were published in the Journal of the American Chemical…
Army researchers explore benefits of immersive technology for soldiers
The emergence of next generation virtual and augmented reality devices like the Oculus Rift and Microsoft HoloLens has increased interest in using mixed reality to simulate training, enhance command and control, and improve the effectiveness of warfighters on the battlefield. It is thought that putting mission relevant battlefield data, such as satellite imagery or body-worn sensor information, into an immersive environment will allow warfighters to…
