The Purdue University research team that recently created a tiny motor out of synthetic biological molecules has found further evidence that RNA molecules can perform physical work, a discovery that could advance nanotechnology and possibly solve fundamental mysteries about life itself.
One promising application of RNA-ATP binding is this microscopic motor, assembled by Peixuan Guos team at Purdue University. The motor, only a few nanometers wide, is formed by six strands of RNA surrounding an "axle" made of DNA. When fed a supply of ATP as fuel, the RNA molecules kick against the DNA in succession, much like the pistons in a conventional motor. (Graphic/Guo Laboratory)
Purdues Peixuan Guo has discovered how viral RNA molecules bind an energy-bearing organic molecule known as ATP. While linking these two substances might seem to create no more than a longer string of letters, the upshot is that now one of lifes most mysterious and ancient storehouses of information can be moved by one of its most important fuels. The discovery could shed light on the fundamental role RNA plays in the creation of living things.
"RNA could be even more of a key player than we realize," said Guo, professor of veterinary pathobiology in Purdues School of Veterinary Medicine. "The fact that it can be made to bind ATP in the phi29 virus could imply that these two molecules were among the first to partner in Earths dance of life."

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
