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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
