A class of molecules whose size, structure and chemical composition have been optimized for photonic use could provide the demanding combination of properties needed to serve as the foundation for low-power, high-speed all-optical signal processing.

There is something about the rhythm and texture of early cinema that has a very different "feel" than modern films. But it's hard to put one's finger on just what that something is. New research may help explain this elusive quality.

Despite a six-year hiatus, a resurrected national physical activity initiative in Canada, ParticipPACTION, still has the potential to succeed thanks to a "sticky" brand fostered over thirty successful years, and support from organizations with health promotion and physical activity as their mandates, University of Alberta researchers have found.

A special issue of Insect Molecular Biology reports the detailed analyses of specific aspects of the genome of the important plant pest, the Pea Aphid.

Brent McBride, a professor of human development at the University of Illinois, says the college drop-out rates of traditional undergraduates who are also full-time parents is a growing problem in the US.

Patients hospitalized with mild to moderate community-acquired pneumonia should not be routinely prescribed prednisolone, a corticosteroid, as it is associated with a recurrence of symptoms after its withdrawal, according to the first randomized double-blind clinical trial to address the subject.

The presence of certain proteins in premalignant oral lesions may predict oral cancer development, Medical College of Georgia researchers said.

Huntington's disease (HD) is a cruel, hereditary condition that leads to physical and mental deterioration and eventually, death. HD sufferers are born with the disease although they don't show symptoms until late in life. In a study published in the Journal of Neuroscience, Stephen Ferguson and Fabiola Ribeiro of Robarts Research Institute at the University of Western Ontario identified a protective pathway in the brain that may explain why symptoms take so long to appear.

Frankfurt neurobiologists show similar structural candidates for a magnetoreceptor in different bird species -- a cooperation with physicists of the Hamburg DESY.

Mayo Clinic researchers along with collaborators from Life Technologies are reporting on the application of a new approach for sequencing RNA to study cancer tumors.

A breakthrough in decoding gene regulation of Helicobacter pylori has been made by an international research team led by Jorg Vogel of the Max Planck Institute for Infection Biology in Berlin. Using a newly developed sequencing technique, the researchers discovered 60 small ribonucleic acids -- tiny RNA-particles which can regulate genes -- in the genome of this human pathogen. These findings could facilitate the development of new therapeutic strategies against this widespread pathogen.

Global chemical companies could release at least one billion Euro in cash flow if they increase their sustainability performance. The claim has been made following an international study which assessed the sustainability performance of nine global chemical companies in monetary terms. Entitled Sustainable Value Creation by Chemical Companies, it has been published by a leading European research team including academics from Queen's University Management School in Belfast.

Researchers from the George Washington University School of Public Health and Health Services said today that asthma, a largely manageable and chronic disease, is on the rise in America and released new data on the magnitude of the asthma crisis, the surging cost of treatment, and the more than 1 million children with asthma who are uninsured.

Have you ever forgotten to post an important letter or let an appointment slip your mind? A new study from UK researchers suggests that for those who regularly use ecstasy or other recreational drugs, this kind of memory lapse is more common. Their research, which uncovered potential links between memory deficits and cocaine for the first time, appears in the Journal of Psychopharmacology, published by SAGE.

Researchers from the University of Zaragoza have calculated the energy and economic potential of urban solid waste, sludge from water treatment plants and livestock slurry for generating electricity in Spain. These residues are alternative sources of renewable energy, which are more environmentally friendly and, in the case of solid urban waste, more cost effective.
