| Two for one in solar power: New process could revolutionize solar energy harvesting Posted: 17 Nov 2013 12:57 PM PST A process that could revolutionize solar energy harvesting has been efficiently demonstrated in solution for the first time.  |
| Scientists invent self-healing battery electrode Posted: 17 Nov 2013 12:57 PM PST Researchers have made the first battery electrode that heals itself, opening a new and potentially commercially viable path for making the next generation of lithium ion batteries for electric cars, cell phones and other devices. The secret is a stretchy polymer that coats the electrode, binds it together and spontaneously heals tiny cracks that develop during battery operation, according to the research.  |
| Graphene nanoribbons for 'reading' DNA Posted: 17 Nov 2013 12:56 PM PST One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. Researchers have found a way to improve this technique by using a material with unique properties: graphene.  |
| Posted: 17 Nov 2013 12:56 PM PST A temporary seismic array in Marie Byrd Land in West Antarctica recorded two bursts of activity in 2010 and 2011. Careful analysis of the events shows they originate from a subglacial volcano at the leading end of a volcanic mountain chain. The volcano is unlikely to erupt through the kilometer of ice that covers it but it will melt enough ice to change the way the ice in its vicinity flows.  |
| 'Mini-kidney' structures generated from human stem cells for first time Posted: 17 Nov 2013 12:54 PM PST Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology.  |
| Nanoparticles to probe mystery sperm defects linked to infertility Posted: 15 Nov 2013 07:47 AM PST A way of using nanoparticles to investigate the mechanisms underlying 'mystery' cases of infertility has been developed by scientists. The technique could eventually help researchers to discover the causes behind cases of unexplained infertility and develop treatments for affected couples. The method involves loading porous silica nanoparticle 'envelopes' with compounds to identify, diagnose or treat the causes of infertility.  |
