Li-ion batteries contain toxic halogens, but environmentally friendly alternatives exist

Physics researchers at Virginia Commonwealth University have discovered that most of the electrolytes used in lithium-ion batteries -- commonly found in consumer electronic devices -- are superhalogens, and that the vast majority of these electrolytes contain toxic halogens.

This is a Saimaa ringed seal.The critically endangered Saimaa ringed seal, which inhabits Lake Saimaa in Finland, has extremely low genetic diversity and this development seems to continue, according to a recent study completed at...

Cutting the ties that bind

An oocyte with decreased Topoiosmerase II levels in heterochromatic region of the X chromosome (green) failed to separate while heterochromatic region of the 4th chromosome (red) is stretched into abnormal projections.The development of a new organism from the joining of two single cells is a carefully orchestrated endeavor. But even before sperm meets egg, an equally elaborate set of choreographed...

Birds roosting in large groups less likely to contract West Nile virus

This is researcher Bethany Krebs (on ladder) assembling one of the flight cages used to house a sentinel sparrow for University of Illinois research on the relationship between roosting and West Nile virus transmission.Although it would seem logical that large numbers of roosting birds would attract more mosquitoes that carry West Nile virus and contract the disease when bitten, recent research at the...

Liquid helium offers a fascinating new way to make charged molecules

A collaboration between researchers at the Universities of Leicester and Innsbruck has developed a completely new way of forming charged molecules which offers tremendous potential for new areas of chemical research.

Molecular beacons shine light on how cells 'crawl'

'Our premise is that mechanics play a role in almost all biological processes, and with these DNA-based tension probes we're going to uncover, measure and map those forces,' says biomolecular chemist Khalid Salaita.Adherent cells, the kind that form the architecture of all multi-cellular organisms, are mechanically engineered with precise forces that allow them to move around and stick to things. Proteins called...

Berkeley Lab study reveals molecular structure of water at gold electrodes

This image depicts from left Miquel Salmeron, Jinghua Guo, David Prendergast, Liwen Wan, Chenghao Wu, Tod Pascal and Juan-Jesus Velasco-Velez.When a solid material is immersed in a liquid, the liquid immediately next to its surface differs from that of the bulk liquid at the molecular level. This interfacial layer...

Paper-based synthetic gene networks could enable rapid detection of ebola and other viruses

Study finds significant increase in type 1 diabetes rates among non-Hispanic white youth

Researchers found that from 2002 to 2009, the rate of type 1 diabetes rose from 24.4 per 100,000 youth in the first year of the study to 27.4 per 100,000 youth in the last year of the study.The rate of non-Hispanic white youth diagnosed with type 1 diabetes increased significantly from 2002 to 2009 in all but the youngest age group of children, according to a new...

No-till agriculture may not bring hoped-for boost in global crop yields, study finds

No-till farming, a key conservation agriculture strategy that avoids conventional plowing and otherwise disturbing the soil, may not bring a hoped-for boost in crop yields in much of the world,...

Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans

Vom Saal's team is providing the first data that BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans.Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage...
