Seeing smoking in films encourages teenagers to try smoking
The more smoking teenagers see in films the more likely they are to smoke, finds a study in this week's BMJ, providing powerful new evidence that depictions of smoking in films influence adolescents to smoke. James Sargent and colleagues surveyed 4,919 schoolchildren in the United States (aged 9-15 years) about the amount of smoking they had seen... view more... (2001-12-12)
Sculptured materials allow multiple channel plasmonic sensors
Sensors, communications devices and imaging equipment that use a prism and a special form of light -- a surface plasmon-polariton -- may incorporate multiple channels or redundant applications if manufacturers use sculptured thin films. view more (2009-11-11)
Study shows schizophrenia limits understanding of body language
Understanding the meaning behind a person's posture or body movement comes easily to many people and helps guide how we react to others socially. view more (2006-05-19)
Caltech scientists solve decade-long mystery of nanopillar formations
Scientists at the California Institute of Technology (Caltech) have uncovered the physical mechanism by which arrays of nanoscale (billionths-of-a-meter) pillars can be grown on polymer films with very high precision, in potentially limitless patterns. view more (2009-10-23)
'Cooper pairs' can be found in insulators as well superconductors
Nearly a century ago, Dutch physicist Kamerlingh Onnes discovered that some metals transform into perfect electrical conductors when cooled to temperatures near absolute zero. Once started, their currents of electrons can flow perpetually. view more (2007-11-26)
Atomic force microscopy reveals liquids adjust viscosity when confined, shaken
Getting ketchup out of the bottle isn't always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated. The opposite is not typically true - a liquid such as water does not become a gel when shaken. view more (2008-04-30)
Edible food wrap kills deadly E. coli bacteria
Researchers have improved upon an edible coating for fresh fruits and vegetables by enabling it to kill deadly E. coli bacteria while also providing a flavor-boost to food. view more (2006-11-17)
Very long term effects of Botox still unknown
The use of botulinum toxin for facial cosmetic enhancement has established its new image as a glamour drug, but its unlicensed use is increasing dramatically for certain conditions, ahead of clear scientific evidence. Although negative side effects are few, its very long term effects are still unknown, warns a neurology expert in this week’s... view more... (2002-11-20)
An Evening of Images of Science for Tomorrow's Europe
Press invitation This evening (7th November) the Musées royaux d'Arts et d'Histoires in Brussels will be the venue for a presentation of the results of the EuroPAWS competition. Guests will be able to see excerpts of the winning TV dramas from the EuroPAWS Awards and see live renditions of new script ideas for future TV dramas bearing on... view more... (2001-10-31)
CT better than plain radiographs in diagnosing lumbar spine fractures
Lumbar spine fractures in a majority of patients with trauma can be detected by routine trauma abdomen and pelvis CT compared to plain radiographs, according to a recent study conducted by radiologists at the University of Cincinnati in Cincinnati, OH. view more (2007-05-07)
Grant award for First Study of Emerging Yeast Species
An emerging species of yeast, Candida parapsilosis is causing increasing numbers of infections because it spreads easily from medical devices into the blood stream of patients. Science Foundation Ireland has recently awarded almost EUR1 million to Dr. Geraldine Butler of the Conway Institute of Biomolecular and Biomedical Research, Dublin for her... view more...

Instants In The Flow - Request Stop
The Novosibirsk researchers have developed a device capable of producing mist with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The precise name of the device is "field device for measuring liquid and gas velocities". It helps to perform prompt, precise... view more... (2005-02-14)
Handsfree mobile phone is no safer in traffic
A VTI study performed in the driving simulator shows that using a mobile phone with a handsfree kit is no safer in traffic than using a hand-held mobile phone. view more (2004-09-13)
Latex means environmentally friendly packaging
For several years, Caisa Andersoon has been trying to create a better barrier against moisture and oxygen in our food packaging. On December 20, she will submit her doctoral dissertation at Karlstad University in Sweden. Latex has long been used for various types of surface treatment of paper. In recent years, interest has been focused on the... view more... (2002-12-17)
A special pallet
The Bizkaian company, Ekoplast Balenciaga, manufacturer of large, high-thickness plastic parts, has developed and patented, in collaboration with the Gaiker technological centre, a novel support for the handling and transport of coils of sheet steel. Made from 100% recyclable plastics from containers, agricultural film, the recycling also... view more... (2004-10-22)
Flexible electronics advance boosts performance, manufacturing
Flexible electronics made with organic, or carbon-based, transistors could enable technologies such as low-cost sensors on product packaging and ''electronic paper'' displays as thin and floppy as a placemat. view more (2006-12-14)
Emory study of former child soldiers yields new data to guide mental health interventions
Former child soldiers in Nepal are more than twice as likely to suffer from symptoms of depression and post-traumatic stress disorder (PTSD) as Nepali children who experienced war trauma as civilians, according to a study led by Brandon Kohrt, an Emory University graduate student. view more (2008-08-14)
Syracuse University researchers build new surface material that resists biofilm growth; new technology may lead to development of improved medical implants
This is the tale of two biological substances-cells from mammals and bacteria. It's a story about the havoc these microscopic entities can wreak on all manner of surfaces, from mighty ships to teeth and medical devices, and how two Syracuse University researchers are discovering new ways to prevent the damage. view more (2009-03-20)
First direct electric link between neurons and light-sensitive nanoparticle films created
The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan. view more (2007-02-28)
On a Wire or in a Fiber, a Wave is a Wave
In an experiment modeled on the classic "Young's double slit experiment" and published in the journal Nature Nanotechnology, researchers have powerfully reinforced the understanding that surface plasmon polaritons (SPPs) propagate and diffract just like any other wave. view more (2007-07-16)
