New materials for stronger wind turbines
United Press International    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A U.S. researcher says he's built a lighter, stronger wind turbine blade that will enable allow larger turbines to capture greater amounts of wind energy. Marcio Loos and others at Case Western Reserve University in Cleveland, have built what they say is the world's first polyurethane blade reinforced with carbon nanotubes — making it lighter and eight times stronger than blades made with current materials such as epoxy resin, fiberglass, carbon fiber and aluminum.

Discovery could create retinas from 'Jell-O'
PhysOrg.com    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers at the University of Toronto have developed a new method for creating 3D hydrogel scaffolds that will aid in the development of new tissue and organs grown in a lab. Hydrogels, a "Jell-O" — like substance, are highly flexible and absorbent networks of polymer strings that are frequently used in tissue engineering to act as a scaffold to aid cellular growth and development.

New laser could treat acne with telecom technology

A laser developed at the University of Michigan is designed to melt fat without burning surrounding tissue. It could potentially be used to treat acne, researchers say. Its 1,708-nanometer, infrared beam takes advantage of a unique wavelength that fat can absorb more efficiently than water, which makes up more than half of the human body. It can penetrate skin with minimal harm on its way to reach and destroy deeper pockets of fat, said Mohammed Islam, a professor of electrical engineering and internal medicine. The research is described in a paper published in Lasers in Surgery and Medicine. More

Revolution in blood sampling
Lab Manager Magazine    Share    Share on FacebookTwitterShare on LinkedinE-mail article
The days of the blood sample routine — arm out, tie tube, make a fist, find a vein and tap in — may soon be over, thanks to a new analysis method developed at the University of Toronto by Institute of Biomaterials and Biomedical Engineering core professor Aaron Wheeler in which only a pinprick of blood necessary. Traditional methods of blood sampling requires intravenous extraction of several millilitres of blood. A phlebotomist then separates serum, which is frozen for transport or storage, and later thawed and analyzed. A relatively new alternative to the traditional method uses blood samples stored as dried blood spots. More

A little vibration can be a good thing for people who need a sensitive touch. Researchers at the Georgia Institute of Technology have developed a glove with a special fingertip designed to improve the wearer's sense of touch. Applying a small vibration to the side of the fingertip improves tactile sensitivity and motor performance, according to their research results. More

Hydrogen fuel produced from sunlight and safely stored

Hydrogen has long been commended as a clean and efficient alternative to gasoline, but so far it hasn't really been able to live up to expectations. Mostly because it has to be derived from nonrenewable sources like coal and natural gas to be cost efficient, but also because it has proven difficult to safely store. Now scientists from the University of Kentucky and the University of Louisville have found an inexpensive semiconductor material that can split water solely using sunlight as its energy source. Their findings were published in the journal Physical Review B. More

Internet could run 10 times faster with graphene
The Huffington Post    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Internet connections could run ten times faster than current speeds, according to research published in the journal Nature Communication. University of Manchester and Cambridge scientists have discovered a key step in improving characteristics of graphene for use as photodetectors in high-speed optical communications. Graphene is a form of carbon just one atom thick and yet 100 times stronger than steel. More
