A bacteriums ability to change its hairstyle may help in the effort to clean contaminated groundwater for drinking, according to Penn State researchers.
People are continually moving into places that are hot, sunny and arid where drinking water is in short supply, says R. Kramer Campen, Penn State graduate student in geosciences. "The imperative to find ways to clean groundwater is paramount," he told attendees today (March 25) at the 225th American Chemical Society national meeting in New Orleans.
In the ocean, bacteria can be released into the water to clean up oil spills, carried to the target by the same currents that transport the oil. Groundwater poses a more difficult problem as these single-cell organisms tend to adhere to certain minerals in the soil preventing them from following the pollutants trail. Bacterial adhesion is also responsible for many medical problems such as tooth decay and artificial limb and organ rejection. "There is a growing awareness that you need a molecular level understanding," says Campen. "At that level, the processes that cause a bacterium to adhere to a mineral in soil or to a tooth have to be the same."

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
