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."

Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.

A new research project at the TH Mittelhessen focusses on the development of a novel light weight design concept for leisure boats and yachts. Professor Stephan Marzi from the THM Institute of Mechanics and Materials collaborates with Krake Catamarane, which is a shipyard located in Apolda, Thuringia.
The project is set up in an international cooperation with Professor Anders Biel from Karlstad University in Sweden and the Swedish company Lamera from...
Superconductivity has fascinated scientists for many years since it offers the potential to revolutionize current technologies. Materials only become superconductors - meaning that electrons can travel in them with no resistance - at very low temperatures. These days, this unique zero resistance superconductivity is commonly found in a number of technologies, such as magnetic resonance imaging (MRI).
Future technologies, however, will harness the total synchrony of electronic behavior in superconductors - a property called the phase. There is currently a...
How do some neutron stars become the strongest magnets in the Universe? A German-British team of astrophysicists has found a possible answer to the question of how these so-called magnetars form. Researchers from Heidelberg, Garching, and Oxford used large computer simulations to demonstrate how the merger of two stars creates strong magnetic fields. If such stars explode in supernovae, magnetars could result.
