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.
Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, including most recently intracranial monitors for patients with traumatic brain injury. The advances suggest a new era of devices that range from green consumer electronics to 'electroceutical' therapies, to biomedical sensor systems that do their work and then disappear.
Using a common laboratory filter paper decorated with gold nanoparticles, researchers have created a unique platform, known as 'plasmonic paper', for detecting and characterizing even trace amounts of chemicals and biologically important molecules - from explosives, chemical warfare agents and environmental pollutants to disease markers.
