Inexpensive microrobots capable of probing and manipulating individual cells and tissue for biological research and medical applications are closer to reality with the design of a system that senses the minute forces exerted by a robot's tiny probe.
Researchers have obtained the first direct observations of atomic diffusion inside a bulk material. The research could be used to give unprecedented insight into the lifespan and properties of new materials.
Scientists have developed a 'smart' lithium-ion battery that gives ample warning before it overheats and bursts into flames. The new technology is designed for conventional lithium-ion batteries now used in billions of cellphones, laptops and other electronic devices, as well as a growing number of cars and airplanes.
Scientists have created a synthetic molecule that mimics HDL cholesterol and have shown it can reduce plaque buildup in the arteries of animal models. The molecule, taken orally, improved cholesterol in just two weeks.
Neutron scattering experiments have revealed the existence of quantum selection rules in molecules, the first experimental confirmation of its kind. Small molecules such as water and hydrogen were inserted into C60 buckyballs to form rare compounds ideal for testing the predictions of quantum theory. Similar confinement techniques could open the door to new insights about the quantum properties of molecules by providing a unique testing ground for quantum theory.
Device is used to monitor brain pressure in lab mice as prelude to possible use with human patients; future applications of this pressure-sensing technology could lead to touch-sensitive 'skin' for prosthetic devices.
A new technique makes it possible to quickly detect the presence of drugs or to monitor certain medical conditions using only a single drop of blood or urine, representing a potential tool for clinicians and law enforcement.
An emerging class of electrically conductive plastics called 'radical polymers' may bring low-cost, transparent solar cells, flexible and lightweight batteries, and ultrathin antistatic coatings for consumer electronics and aircraft.
