| Think globally, but act locally when studying plants, animals, global warming, researchers advise Posted: 20 Mar 2011 01:42 PM PDT Global warming is clearly affecting plants and animals, but we should not try to tease apart the specific contribution of greenhouse gas driven climate change to extinctions or declines of species at local scales, biologists advise. |
| Organic nanoparticle uses sound and heat to find and treat tumors Posted: 20 Mar 2011 01:42 PM PDT Scientists have created an organic nanoparticle that is completely non-toxic, biodegradable and nimble in the way it uses light and heat to treat cancer and deliver drugs. |
| Major clue in long-term memory-making Posted: 20 Mar 2011 01:42 PM PDT You may remember the color of your loved one's eyes for years. But how? Scientists believe that long-term potentiation (LTP) -- the long-lasting increase of signals across a connection between brain cells -- underlies our ability to remember over time and to learn, but how that happens is a central question in neuroscience. |
| Posted: 20 Mar 2011 01:42 PM PDT Direct experience of extreme weather events increases concern about climate change and willingness to engage in energy-saving behavior, according to new research. In particular, members of the British public are more prepared to take personal action and reduce their energy use when they perceive their local area has a greater vulnerability to flooding, according to the research. |
| Batteries charge quickly and retain capacity, thanks to new structure Posted: 20 Mar 2011 01:42 PM PDT Scientists have developed a three-dimensional nanostructure for battery cathodes that allows for dramatically faster charging and discharging without sacrificing energy storage capacity. Such batteries could be useful for quick-charge consumer electronics, electric vehicles, medical devices, lasers and military applications. |
| Mutant prions help cells foil harmful protein misfolding Posted: 20 Mar 2011 01:42 PM PDT Misfolded proteins are implicated in many incurable neurological diseases. A new and improved understanding of how naturally occurring variants keep proteins from bunching up and spreading provides more options for developing a treatment than scientists had realized. |
| New imaging technique provides rapid, high-definition chemistry Posted: 20 Mar 2011 01:42 PM PDT With intensity a million times brighter than sunlight, a new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality. The new technique employs multiple beams of synchrotron light to illuminate a state-of-the-art camera, instead of just one beam. It could have broad applications in a wide array of fields from medicine and forensics to biofuel production and advanced materials. |
