Dolphins, long considered the second-smartest species on the planet, recognize one another by name, possess a distinct concept of "self’ and, it turns out, have some surprisingly good ideas about techniques for keeping the hulls of maritime ships clean.
Karen L. Wooley, Ph.D., professor of chemistry at Washington University in St. Louis, has noted the shape and texture of dolphin skin and how it naturally prevents marine creatures from clinging to dolphin skin. The observation fits into her study of finding ways to mediate interactions between biological systems and synthetic materials, designing chemical "functionalities," or groups of atoms, that either promote or discourage binding between them.
In one recent example, Wooley and collaborator John-Stephen A. Taylor, Ph.D., Washington University professor of chemistry, hope to employ nanoparticles that will take advantage of naturally occurring chemical interactions to deliver therapeutic drugs directly to diseased cells. At the same time, Wooley currently is developing a group of nontoxic "antifouling" coatings that may one day inhibit marine organisms such as barnacles, tube worms and zoo spores from attaching to, say, the hulls of ships.

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...
