Biomimicry News And Research- Nanotechnology may increase longevity of dental fillingsTooth-colored fillings may be more attractive than silver ones, but the bonds between the white filling and the tooth quickly age and degrade. A Medical College of Georgia researcher hopes a new nanotechnology technique will extend the fillings' longevity.
- Stirred, not shaken: Bio-inspired cilia mix medical reagents at small scalesEngineers used a novel underwater manufacturing technique to successfully build biomimetic cilia. The hairlike appendages mix tiny volumes of liquid to speed up biomedical reactions.
- Crustacean shell with polyester creates mixed-fiber material for nerve repairWeaving chitosan, found in the shells of crabs and shrimp, with an industrial polyester creates a promising new material for biomedical applications, including the tiny tubes that support repair of a severed nerve.
- Beetle shell inspires brilliant white paperAn obscure species of beetle has shown how brilliant white paper could be produced in a completely new way. A team from Imerys Minerals Ltd. and the University of Exeter has taken inspiration from the shell of the Cyphochilus beetle to understand how to produce a new kind of white coating for paper.
- New radio chip mimics human earCould enable wireless devices capable of receiving cell phone, Internet, radio and television signals
- Navy grant to fund probe of squid and octopus camouflageOctopuses and squid are big brained species that use much of their mental powers to adjust their own appearances. This remarkable ability to camouflage on the fly has inspired the US Office of Naval Research to award $7.5 million to Duke University and two collaborating institutions to learn more about how the animals do it.
- Getting a grip: 'Velcro'-like structure helps bees stick to flowersWhen bees collect nectar, how do they hold onto the flower? Cambridge University scientists have shown that it is down to small cone-shaped cells on the petals that act like Velcro on the bees' feet.
- 'Gecko vision': Key to the multifocal contact lens of the future?Nocturnal geckos are among the very few living creatures able to see colors at night, and scientists' discovery of series of distinct concentric zones may lead to insight into better cameras and contact lenses.
- Research gives clues for self-cleaning materials, water-striding robotsHumans have marveled for millennia at how water beads up and rolls off flowers, caterpillars and some insects, and how insects like water striders are able to walk effortlessly on water. University of Nebraska and RIKEN research into super hydrophobic properties provide hints to researchers to develop these abilities in things like micro-robots, self-cleani […]

- Drill Bits: Rig Count Picks Up Again. Why?U.S. oil drilling is picking up and natural gas drilling is flattening off. With oil and gas prices so weak, why is this happening?
- Renewable Energy Financing Rebounds, in Europe, if not U.S.Renewable energy projects -- wind farms, solar parks, etc. -- are getting funding again after a long freeze in the markets. But the pace of financing in Europe is well ahead of the U.S.
- Oil Prices: A Year After a Record $145, Gloom PrevailsOil prices fell on Thursday due to bad U.S. employment news and word that OPEC discipline may be wavering. One year after $145-a-barrel oil and it doesn't appear those prices are returning anytime soon.

- Pinpointing Drought Coast to CoastTake vast quantities of satellite remote sensing data. Season with time. Mix generously with information about climate, soils, and recent rainfall. These are the ingredients for the Vegetation Drought Response Index. Known to specialists as VegDRI, this computer modeling and monitoring method provides continuous drought information over large regions and sup […]
- Beach Health: Safe to Swim?When a local beach closes for health reasons, people start wondering, “Is it safe to swim?” U.S. Geological Survey (USGS) science can help local beach managers understand the sources of contamination and the kinds of contaminants that may affect human health. In the Great Lakes region, the USGS has already developed state-of-the-art methods and p […]
- Nutrient Delivery to the Gulf of Mexico Among Highest MeasuredSpring nutrient delivery to the northern Gulf of Mexico is among the highest measured by the U.S. Geological Survey (USGS) in thirty years. Too many nutrients, which are essential for plant growth, are not necessarily a good thing. Excessive nutrients can be harmful by decreasing the amount of oxygen in the water, also known as hypoxia. This can result in an […]
