Nanotechnology: Better measurements of single molecule circuits Posted: 18 Feb 2015 11:55 AM PST A new technique gives better measurements of the properties of electrical circuits made of single molecules. The method should enable more research in nanotechnology, researchers report.

Keeping atherosclerosis in-check with novel targeted inflammation-resolving nanomedicines Posted: 18 Feb 2015 11:55 AM PST Nanometer-sized 'drones' that deliver a special type of healing molecule to fat deposits in arteries could become a new way to prevent heart attacks caused by atherosclerosis, according to a study in pre-clinical models.

3-D engineered bone marrow makes functioning platelets Posted: 18 Feb 2015 09:31 AM PST An international research team has reported development of the first three-dimensional tissue system that reproduces the complex structure and physiology of human bone marrow and successfully generates functional human platelets. Using a biomaterial matrix of porous silk, the new system is capable of producing platelets for future clinical use and also provides a laboratory tissue system to advance study of blood platelet diseases.

Breakthrough in nanotoxicology by researchers Posted: 18 Feb 2015 06:30 AM PST Whereas resistance to antibiotics complicates certain treatments, antimicrobial silver nanoparticles are gaining popularity for medical use. These particles are toxic for certain bacteria, but what about for humans? Researchers have taken a step toward understanding the cellular and molecular mechanisms that affect these particles

Cost-effective and efficient rival for platinum Posted: 18 Feb 2015 04:31 AM PST Researchers have succeeded in creating an electrocatalyst that is needed for storing electric energy made of carbon and iron.

Igniting the air for atmospheric research Posted: 18 Feb 2015 04:30 AM PST Scientists have created a high-energy mid-infrared laser powerful enough to create shining filaments in the air. Such devices could be used to detect chemical substances in the atmosphere.

New device improves healing of some ruptured aneurysms Posted: 11 Feb 2015 12:38 PM PST Among some patients, a new device called a HydroCoil inserted into ruptured blood vessels in the brain significantly improved healing of the aneurysm compared to a standard device. The device, which contains a gel that expands when it comes into contact with blood, was effective among patients with medium-sized aneurysms that had already ruptured.
