Scientists concerned about environmental impact of recycling of e-waste

CORVALLIS, Ore. – Much of the world's electronic waste is being shipped to China for recycling and the cottage industry that has sprung up there to recover usable materials from computers, cell phones, televisions and other goods may be creating significant health and environmental hazards.

OU GeoChip technology plays critical role in Gulf of Mexico deepwater oil plume study

A University of Oklahoma technology—GeoChip—played a critical role in an intensive study of the dispersed oil plume that formed at a depth between 3,600 and 4,000 feet some 10 miles from BP's Deepwater Horizon drilling rig in the Gulf of Mexico.

An OU research team led by Jizhong Zhou, director of the Institute for Environmental Genomics, developed the new generation GeoChip, which contributed to the findings of the study by simultaneously detecting more than 150,000 different functional genes for various microbial ecological and biogeochemical processes.

Secrets of the gecko foot help robot climb

Secrets of the gecko foot help robot climb

The interaction between the molecules of gecko toe hair and the wall is a molecular attraction called van der Waals force. A gecko can hang and support its whole weight on one toe by placing it on the glass and then pulling it back. It only sticks when you pull in one direction – their toes are a kind of one-way adhesive, Cutkosky said.

Who hasn't had dental cavities?

A research study has for the first time revealed data about dental cavities, periodontal disease, oral treatment needs, the use of dental prostheses and dental hygiene habits among the adult population in the Valencia region. The results show that 90% of people have cavities and 20-35% need prostheses.

"These data will make it possible to draw comparisons with other studies carried out in other autonomous regions and nationwide ones", José Manuel Almerich, co-author of the study and a scientist at the University of Valencia (UV), tells SINC.

Electricity collected from the air could become the newest alternative energy source

BOSTON, Aug. 25, 2010 — Imagine devices that capture electricity from the air ― much like solar cells capture sunlight ― and using them to light a house or recharge an electric car. Imagine using similar panels on the rooftops of buildings to prevent lightning before it forms. Strange as it may sound, scientists already are in the early stages of developing such devices, according to a report presented here today at the 240th National Meeting of the American Chemical Society (ACS).

Doctors' religious beliefs strongly influence end-of-life decisions

Atheist or agnostic doctors are almost twice as willing to take decisions that they think will hasten the end of a very sick patient's life as doctors who are deeply religious, suggests research published online in the Journal of Medical Ethics.

And doctors with a strong faith are less likely to discuss this type of treatment with the patient concerned, the research shows.

Banana plantain fibers could treat Crohn's disease

Crohn's is a condition that affects one in 800 people in the UK and causes chronic intestinal inflammation, leading to pain, bleeding and diarrhoea. Researchers are working with biotechnology company, Provexis, to test a new plantain based food product that could treat patients with the disease.

Fuel treatments reduce wildfire severity, tree mortality in Washington forests

A study conducted by U.S. Forest Service and University of Washington (UW) scientists has found that fuel treatments—even of only a few acres—can reduce fire severity and protect older trees desirable for their timber, wildlife, and carbon-storage value. The finding is part of a three-year study of the 175,000-acre Tripod Fire and is published in the August issue of Canadian Journal of Forest Research.

Seeing the world with new eyes: Biosynthetic corneas restore vision in humans

 Biosynthetic corneas restore vision in humans

A new study from researchers in Canada and Sweden has shown that biosynthetic corneas can help regenerate and repair damaged eye tissue and improve vision in humans. The results, from an early phase clinical trial with 10 patients, are published in the August 25th, 2010 issue of Science Translational Medicine.

Created: Glass that optimizes use of solar energy

The Construction Unit at Tecnalia is taking part in the Sunglass project, which involves a glass that augments the efficiency of photovoltaic solar systems, which could boost use of renewable energy in the construction sector.

Microneedle, quantum dot study opens door to new clinical cancer tools

Microneedle, quantum dot study opens door to new clinical cancer tools

Researchers from North Carolina State University have developed extremely small microneedles that can be used to deliver medically-relevant nanoscale dyes called quantum dots into skin – an advance that opens the door to new techniques for diagnosing and treating a variety of medical conditions, including skin cancer.

Juicing up laptops and cell phones with soda pop or vegetable oil?

BOSTON, Aug. 25, 2010 — Scientists today reported development of a new battery-like device that opens the possibility that people one day could "recharge" cell phones, laptops, and other portable electronics in an unlikely way ― with a sugar fix from a shared sip of soda pop or even a dose of vegetable oil. They described the device, the first fuel cell that produces electricity with technology borrowed from the biological powerhouses that energize people and other living things on Earth, here at the 240th National Meeting of the American Chemical Society (ACS).

Coral off Puerto Rico's coast 'ideal case study' for Gulf oil spill's impact

Coral off Puerto Rico's coast 'ideal case study' for Gulf oil spill's impact

Coral living off the coast of Puerto Rico may provide researchers valuable information about the potential impact of the Gulf of Mexico oil spill.

Smallest U-M logo demonstrates advanced display technology

ANN ARBOR, Mich.---In a step toward more efficient, smaller and higher-definition display screens, a University of Michigan professor has developed a new type of color filter made of nano-thin sheets of metal with precisely spaced gratings.

The gratings, sliced into metal-dielectric-metal stacks, act as resonators. They trap and transmit light of a particular color, or wavelength, said Jay Guo, an associate professor in the Department of Electrical Engineering and Computer Science. A dielectric is a material that does not conduct electricity.
