Mimicking Mother Nature's genius as a designer is one of the most promising approaches for developing new medicines, sustainable sources of food and energy, and other products that society needs to meet the great challenges that lie ahead in the 21st century, a noted scientist said here today.

 | Researchers are creating a new type of solar cell designed to self-repair like natural photosynthetic systems in plants by using carbon nanotubes and DNA, an approach aimed at increasing service life and reducing cost. ...> Full Article |
 | To survive in a tumultuous environment, sea urchins literally eat through stone, using their teeth to carve out nooks where the spiny creatures hide from predators and protect themselves from the crashing surf on the rocky shores and tide pools where they live.

 | Nanotechnologists, marine biologists and signal-processing experts from Rice University, the Marine Biological Laboratory in Woods Hole, Mass., and other US universities have won $6 million from the Office of Naval Research to unlock the secrets of nature's best camouflage artists. Ultimately, the team hopes to create "metamaterials" -- materials that blur the line between material and device -- to emulate the elegant colors and patterns that are produced by squid and other marine animals. ...> Full Article |
 | Rice graduate student Cary Pint has come up with a way to transfer forests of strongly aligned, single-walled carbon nanotubes from one surface to another -- any surface -- in a matter of minutes. The template used to grow the nanotubes, with its catalyst particles still intact, can be used repeatedly to grow more nanotubes, almost like inking a rubber stamp. ...> Full Article |
 | A team of researchers from the State University of Pennsylvania and the Universidad Autonoma de Madrid have developed a technique to replicate biological structures, such as butterfly wings, on a nano scale. The resulting biomaterial could be used to make optically active structures, such as optical diffusers for solar panels. ...> Full Article |

 | Successful construction of a gecko-inspired adhesive that is ten times stronger than a gecko, at about 100 newtons per square centimeter. ...> Full Article |
 | The ability of carbon nanotubes to withstand repeated stress yet retain their structural and mechanical integrity is similar to the behavior of soft tissue, according to a new study from Rensselaer Polytechnic Institute. ...> Full Article |
A semiconductor membrane designed by researchers at the University of Illinois could offer more flexibility and better electrical performance than biological membranes. Built from thin silicon layers doped with different impurities, the solid-state membrane also could be used in applications such as single-molecule detection, protein filtering and DNA sequencing

 | Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers at Rensselaer Polytechnic Institute and the University of Akron have taken one sticky step in the right direction, creating synthetic 'gecko tape' with four times the sticking power of the real thing. ...> Full Article |
