Mechanism of wine swirling explained
— 21 Nov 2011 19:16 | PhysicsWine drinkers know that swirling a good vintage around in a glass aerates the wine and releases its bouquet. Just how the process - known as 'orbital shaking' - works, however, has…
Nanoparticles improve solar collection efficiency
— 6 Apr 2011 18:19 | TechnologyUsing minute graphite particles 1000 times smaller than the width of a human hair, mechanical engineers at Arizona State University hope to boost the efficiency - and profitability…
Inexpensive new instruments test building sealants under real-world conditions
— 6 Apr 2011 18:16 | TechnologySealants, like weather stripping, are what separates the inside from the outside of a building, byproviding a barrier that prevents water from seeping in, for example, or heat from…
Force of acoustical waves tapped for metamaterials
— 6 Apr 2011 18:13 | TechnologyA very simple bench-top technique that uses the force of acoustical waves to create a variety of 3D structures will benefit the rapidly expanding field of metamaterials and their myriad…
Tiny 'on-chip detectors' count individual photons
— 17 Mar 2011 20:54 | TechnologyA team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called 'single-photon avalanche diodes (SPAD),' act like…
Physicists move closer to efficient single-photon sources
— 17 Mar 2011 20:49 | PhysicsA team of physicists in the United Kingdom has taken a giant step toward realising efficient single-photon sources, which are expected to enable much-coveted completely secure optical…
Breaking the mucus barrier unveils cancer cell secrets
— 17 Mar 2011 20:44 | HealthMeasuring the mechanical strength of cancer cell mucus layers provides clues about better ways to treat cancer, and also suggests why some cancer cells are more resistant to drugs than…
Newly identified spider toxin may help uncover novel ways of treating pain and human diseases
— 10 Mar 2011 18:38 | HealthSpider venom toxins are useful tools for exploring how ion channels operate in the body. These channels control the flow of ions across cell membranes, and are key components in a wide…
Researchers find novel role for calcium channels in pacemaker cell function
— 9 Mar 2011 20:47 | HealthPacemaker cells in the sinoatrial node control heart rate, but what controls the ticking of these pacemaker cells? New research by Angelo Torrente and his colleagues of the M.E. Mangoni…
New mouse models generated for MYH9 genetic disorders
— 9 Mar 2011 20:44 | HealthResearchers have created the first mouse models of human MYH9 genetic disorders, which cause several problems - including enlarged platelets and sometimes fatal kidney disease…
