Processes and policies governing the reuse and recycling of electronic products need to be standardized worldwide to stem and reverse the growing problem of illegal and harmful e-waste processing practices in developing countries, according to experts behind the world's first international e-waste academy.

Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices. But some fundamental issues remain to be resolved – among them, how to position and manipulate the tiny tubes.

Researchers are developing technologies that use lasers to create arterial stents and longer-lasting medical implants that could be manufactured 10 times faster and also less expensively than is now possible.

New technologies will be needed to meet the huge global market for artificial hips and knees, said Yung Shin, a professor of mechanical engineering and director of Purdue's Center for Laser-Based Manufacturing.

MAYWOOD, Il. – A key statistic that consumer groups and the media often use when compiling hospital report cards and national rankings can be misleading, researchers report in a new study.

The statistic is called the mortality index. A number above 1.0 indicates a hospital had more deaths than expected within a given specialty. Lower than 1.0 means there were fewer than the expected number of deaths.

Scientists at Oregon State University have developed a new "adjuvant" that potentially could allow the creation of important new vaccines, become a universal vaccine carrier, and help medical experts tackle diseases more effectively.

Adjuvants are substances that are not immunogenic themselves, but increase the immune response when used in combination with a vaccine.

Scientists have found that laser therapy is equivalent to two different dosages of corticosteroid medications for treating vision loss from the blockage of small veins in the back of the eye, a condition known as branch retinal vein occlusion (BRVO). Furthermore, laser treatment was shown to have fewer complications for patients.

This research was part of the Standard Care vs. Corticosteroid for Retinal Vein Occlusion (SCORE) Study, a phase III clinical trial conducted at 84 sites and supported by the National Eye Institute (NEI) at the National Institutes of Health.

Scientists have identified the first long-term, effective treatment to improve vision and reduce vision loss associated with blockage of large veins in the eye. This research was part of a multi-center, phase III clinical trial supported by the National Eye Institute (NEI) at the National Institutes of Health.

Treating second-degree burns with a nanoemulsion lotion sharply curbs bacterial growth and reduces inflammation that can otherwise jeopardize recovery, University of Michigan scientists have shown in initial laboratory studies.

U-M burn surgeon Mark R. Hemmila, M.D., reports today at the Interscience Conference for Antimicrobial Agents and Chemotherapy on results achieved with a nanoemulsion developed at U-M and licensed by U-M to Ann Arbor-based NanoBio Corporation.

A new study by a University of Warwick researcher has demonstrated that researchers trying to model a range of processes could use the power and capabilities of a particular XBox chip as a much cheaper alternative to other forms of parallel processing hardware.

There are components that save lives: if a car rolls over during an accident, the 'B-pillar' plays a key role. It forms one of the connections between the floor and roof of the vehicle and is designed to prevent the passenger cell from deforming too much. The materials from which the B-pillar is manufactured therefore need to meet very exacting requirements: to save fuel they need to be ultra-lightweight, yet at the same time need to be tremendously strong and must not break. Yet what does the optimum component actually look like?
