One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them.
Scientists at the Swedish medical university Karolinska Institutet and Linköping University are well on the way to creating the first artificial nerve cell that can communicate specifically with nerve cells in the body using neurotransmitters.
A group of researchers from the Department of Physics at UAB have designed a device, called a dc metamaterial, which makes objects invisible under certain light by making the inside of the magnetic field zero but not altering the exterior field. The device, which up to date has only been studied in theoretical works, thus acts as an invisibility cloak, making the object completely undetectable to these waves.
Three proposals from Nanyang Technological University (NTU) have won up to S$30 million in research fund from the National Research Foundation following its fourth call for proposals under its Competitive Research Programme Funding Scheme.
Features in the July issue of Physics World include a close look at how physics is informing our understanding of cells and of the brain, while Paul Davies, a physicist, astrobiologist and director of BEYOND: Center for Fundamental Concepts in Science at Arizona State University, suggests there are tentative signs that life itself may have arisen as a result of physicists' long-cherished theory of quantum mechanics.
The Environmental Working Group (EWG), a United States-based non-governmental organization that works to expose threats to health and the environment, has released their 2009 Sunscreen Report. The investigators expected to recommend against the use of micronized and nano-sized zinc oxide and titanium dioxide sunscreen, but after months of research and analysis of nearly 400 peer-reviewed studies, they found themselves recommending some sunscreens that may contain nanoparticles.
Physicists at the National Institute of Standards and Technology (NIST) have overcome a hurdle in quantum computer development, having devised a viable way to manipulate a single 'bit' in a quantum processor without disturbing the information stored in its neighbors
The device is an embedded microsensor capable of measuring real-time water stress in living plants. In theory, the sensor will help vintners strike the precise balance between drought and overwatering - both of which diminish the quality of wine grapes.
A century after German physicist Gustav Mie derived the math to explain why the colors in some stained glass windows look especially resplendent in the sunlight, a team of Stanford engineers has built upon his work to potentially improve a means of harvesting energy from the sun.
Self-assembling and self-organizing systems are the Holy Grails of nanotechnology, but nature has been producing such systems for millions of years. A team of scientists has taken a unique look at how thousands of bacterial membrane proteins are able to assemble into clusters that direct cell movement to select chemicals in their environment.
X-rays can be used to image hidden structures such as bones of the human body. But now, a team of physicists has succeeded in demonstrating the electronic structure of an interface in a solid for the first time
A team of Canadian scientists and engineers, led by the University of Alberta and the National Research Council of Canada, will collaborate on a $3.39 million, three-year study to assess the potential effects of nanoparticles in specific water environments.
The red and blue images appear ghostly, like a fleeting glimpse of something that's never been seen before - which is true. Using computer simulations, Berkeley Lab scientists have developed the first predicted images of water molecules surrounding a nanoparticle, in this case an iron-oxide mineral called hematite.
