Novel materials shake ship scum
Just as horses shake off pesky flies by twitching their skin, ships may soon be able to shed the unwanted accumulation of bacteria and other marine growth with the flick of a switch.

(Phys.org)—Transposable elements are mobile strands of DNA that insert themselves into chromosomes with mostly harmful consequences. Cells try to keep them locked down, but in a new study, Brown University ...
A team of researchers led by the Universitat Autonoma de Barcelona in Spain has found the first ancient remains of a calcified ovarian teratoma, in the pelvis of the skeleton of a woman from the Roman era. ...
(Phys.org)—The atomic structure of a zinc-based material has a surprising amount in common with the tentacles of an octopus, Oxford University researchers have found.
With 3.5 billion years of research and development under her belt, Mother Nature could be considered the world's most experienced biological engineer. Sure, her methods may appear haphazard at times, but ...
Safety fears about carbon nanotubes, due to their structural similarity to asbestos, have been alleviated following research showing that reducing their length removes their toxic properties.
(Phys.org)—Nanotechnology, the manipulation of matter at the atomic and molecular scale, holds great promise for everything from incredibly fast computers to chemical sensors that can sniff out cancer cells. ...
(Phys.org)—British researchers at King's College in London have succeeded in creating quantum dots by feeding earthworms soil laced with certain metals and then collecting the material excreted. They describe ...
The Structural Technology Group at the Polytechnic University of Catalonia has developed and patented a type of biological concrete that supports the natural, accelerated growth of pigmented organisms. The ...
For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key ...
(Phys.org)—In nature, biological functions are often carried out in tiny protective shells known as microcompartments, structures that provide home to enzymes that convert carbon dioxide into energy in plant cells and to ...
Long ago, when life on our planet was in its infancy, a group of small single-celled algae floating in the vast prehistoric ocean swam freely by beating whip-like tails, called flagella. It's a relatively unremarkable tale, ...
Scientists have taken inspiration from one of the oldest natural materials to exploit the extraordinary qualities of graphene, a material set to revolutionise fields from computers and batteries to composite ...
(Phys.org)—Living in an environment teaming with bacteria and fungi, fish have evolved powerful defenses against waterborne pathogens, including antimicrobial peptides located in their gills. Undergraduate ...
