Sculptured Materials Allow Multiple Channel Plasmonic Sensors

November 17, 2009

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.
"Everyone uses surface plasmon resonance sensors. They are a multi billion-dollar industry worldwide," said Akhlesh Lakhtakia, the Charles Godfrey Binder (Endowed) professor [...]

Genetic Changes Shown to Be Important Indicators for Disease Progression in Cervical Cancer Patients

November 17, 2009

Cervical cancer patients with specific changes in the cancer genome have a three- or fourfold increased risk of relapse after standard treatment compared to patients without these changes, according to a study by Norwegian researchers published November 13 in the open-access journal PLoS Genetics. The research suggests that specific genetic changes are crucial steps in [...]

Lab Machine to Study Glacial Sliding Related to Rising Sea Levels Created

November 17, 2009

Neal Iverson opened his laboratory`s walk-in freezer and said the one-of-a-kind machine inside could help scientists understand how glaciers slide across their beds. And that could help researchers predict how glaciers will react to climate change and contribute to rising sea levels.
Iverson is an Iowa State University professor of geological and atmospheric sciences. He`s worked [...]

Runners: Train Less and Be Faster

November 17, 2009

In a recent scientific study just published in the Journal of Applied Physiology, Bangsbo and co-workers demonstrate that by reducing the volume of training by 25% and introducing the so-called speed endurance training (6-12 30-s sprint runs 3-4 times a week), endurance trained runners can improve not only short-term but also long-term performance.
Thus, the runners [...]

Facial Biometrics System Capable of Creating a Facial `DNA`

November 17, 2009

Research into techniques of facial biometrics, carried out by scientists at Universidad Carlos III de Madrid (UC3M), has resulted in a system that is able to recognize the facial "DNA" of every individual by determining his/her most noteworthy facial traits, with a of 95% rate of precision.
Recognition techniques based on facial features, known as facial [...]

Biosensor to Help Enlist Cancer Resistance Fighters?

November 17, 2009

A powerful new biosensor developed by European researchers will help identify cells in the immune system that actively suppress tumour growth, then put them to use. Enlisting the patient`s own immune system would be like sending reinforcements for resistance fighters.
Cancer is a major killer and an intractable problem confronting medical science, but now European researchers [...]

United States Using Less Water Than 35 Years Ago

November 17, 2009

The United States is using less water than during the peak years of 1975 and 1980, according to water use estimates for 2005. Despite a 30 percent population increase during the past 25 years, overall water use has remained fairly stable according to a new U.S. Geological Survey report.
Assistant Secretary of the Interior Anne Castle [...]

Dissolved Arsenic in Bangladesh Drinking Water Is from Human Alteration of Landscape

November 17, 2009

Researchers in MIT`s Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. The research suggests that human alteration to the landscape, the construction of [...]

Inadequate Levels of Vitamin D May Significantly Increase Risk of Stroke, Heart Disease and Death

November 17, 2009

While mothers have known that feeding their kids milk builds strong bones, a new study by researchers at the Heart Institute at Intermountain Medical Center in Salt Lake City suggests that Vitamin D contributes to a strong and healthy heart as well — and that inadequate levels of the vitamin may significantly increase a person`s [...]
