New research at Rice University could ultimately show scientists the way to make batches of nanotubes of a single type.

A paper in the online journal Physical Review Letters unveils an elegant formula by Rice University physicist Boris Yakobson and his colleagues that defines the energy of a piece of graphene cut at any angle.

An international team of researchers led by the University of East Anglia (UEA) have developed a new kind of endoscope to aid the early detection and diagnosis of inflammatory bowel disease.

The Confocal Laser Endomicroscope (CLE) contains a powerful microscope which allows clinicians to view the bacteria that are thought to trigger diseases of the bowel such as Crohn's disease and ulcerative colitis.

Researchers in South America have studied the viability of using earthworms to process hazardous material containing high concentrations of heavy metal for the bioremediation of old industrial sites, landfill and other potentially hazardous areas. They provide details of a possible approach in the International Journal of Global Environmental Issues this month.

The LouseBuster returns

SALT LAKE CITY, Dec. 6, 2010 – Four years after the LouseBuster prototype made headlines when research showed the chemical-free, warm-air device wiped out head lice on children, a new study reveals that a revamped, government-cleared model is highly effective.

Researchers at Northwestern University have nanoengineered a new kind of fiber that could be tougher than Kevlar.

What can ice reveal about fire?

Scientists studying a column of Antarctic ice spanning 650 years have found evidence for fluctuations in biomass burning--the consumption of wood, peat and other materials in wildfires, cooking fires and communal fires--in the Southern Hemisphere.

DENVER (December 2, 2010) – Fresh water and reusable energy. Humans are on a constant hunt for a sustainable supply of both. Water purification requires a lot of energy, while utility companies need large amounts of water for energy production. Their goal is to find a low-energy-required treatment technology. Researchers from the University of Colorado Denver College of Engineering and Applied Science may have discovered an answer.

The increased availability and access of broadband around the world has meant a rise in global demand for online media services and this could have implications for a society that is living within environmental limits. New research has analysed the potential future demand for downloaded data worldwide, such as social networking sites and on-demand TV programs, and the resulting energy requirements.

 'Watchful waiting' has a new set of eyes

A UCSF research collaboration with GE Healthcare has produced the first results in humans of a new technology that promises to rapidly assess the presence and aggressiveness of prostate tumors in real time, by imaging the tumor's metabolism.

Researchers fabricate more efficient polymer solar cells

AMES, Iowa – Researchers from Iowa State University and the Ames Laboratory have developed a process capable of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by increasing light absorption.

Rice University researchers have discovered a simple way to make carbon nanotubes shine brighter.

The Rice lab of researcher Bruce Weisman, a pioneer in nanotube spectroscopy, found that adding tiny amounts of ozone to batches of single-walled carbon nanotubes and exposing them to light decorates all the nanotubes with oxygen atoms and systematically changes their near-infrared fluorescence.

Chemical reactions on nanotube surfaces generally kill their limited natural fluorescence, Weisman said. But the new process actually enhances the intensity and shifts the wavelength.
