Philadelphia, PA, January 23, 2013 – The Nutrition Facts label was introduced 20 years ago and provides consumers with important information, including: the serving size, the number of servings in the package, the number of calories per serving, and the amount of nutrients for each serving of a packaged food. However, research has shown that consumers often miscalculate the number of calories and the nutritional content of products that have two or more servings per container but are usually consumed in a single eating occasion.

UNIVERSITY PARK, Pa. -- Forging public and private partnerships that encourage broadband access for people with disabilities may help bridge a technological divide that hinders them from reaching their potential, according to an international team of researchers.
Besides connecting people who have disabilities with resources that may help them become more independent, equipping them with broadband technology can also benefit society and ease the financial burden on taxpayers, said Krishna Jayakar, associate professor of communications, Penn State.
BUFFALO, N.Y. — Super-small particles of silicon react with water to produce hydrogen almost instantaneously, according to University at Buffalo researchers.
In a series of experiments, the scientists created spherical silicon particles about 10 nanometers in diameter. When combined with water, these particles reacted to form silicic acid (a nontoxic byproduct) and hydrogen — a potential source of energy for fuel cells.
Bad news about the economy could cause you to pack on the pounds, according to a new study published in Psychological Science, a journal of the Association for Psychological Science.
The study shows that when there is a perception of tough times, people tend to seek higher-calorie foods that will keep them satisfied longer. When subconsciously primed with such messages, a "live for today" impulse is triggered causing people to consume nearly 40 percent more food than when compared to a control group primed with neutral words.
(Garrison, NY) Arguing that obesity "may be the most difficult and elusive public health problem the United States has ever encountered" and that anti-obesity efforts having made little discernible difference, Daniel Callahan, co-founder and President Emeritus of The Hastings Center, proposes a bold and controversial approach to fighting the epidemic.
Scientists at CSIRO and RMIT University have produced a new two-dimensional material that could revolutionise the electronics market, making "nano" more than just a marketing term.
The material – made up of layers of crystal known as molybdenum oxides – has unique properties that encourage the free flow of electrons at ultra-high speeds.
In a paper published in the January issue of materials science journal Advanced Materials, the researchers explain how they adapted a revolutionary material known as graphene to create a new conductive nano-material.
KANSAS CITY, MO – Over the past several years, Rong Li, Ph.D., at the Stowers Institute for Medical Research has been making crucial discoveries about the development of cell polarity—the process by which one side of a cell becomes different from the other side. Such polarity is critical for the functioning of the vast majority of cells. The outside surface of skin cells is very different from the surface inside the body, for example, while nerve cells have delicately branching dendrites on one end and axons on the other.
Researchers at Eindhoven University of Technology (TU/e) together with researchers at the Hong Kong Polytechnic University (PolyU), have developed a special treatment for cotton fabric that allows the cotton to absorb exceptional amounts of water from misty air: 340 % of its own weight. What makes this 'coated cotton' so interesting is that the cotton releases the collected water by itself, as it gets warmer. This property makes of the coated cotton materials a potential solution to provide water to the desert regions, for example for agricultural purposes.
These mechanisms, described in vivo in mice, engage molecule CD98hc, which is involved in epidermis renewal and could be an indicator of the skin's capacity for regeneration.
The results were published in the Journal of Experimental Medicine review.
The fate of mature T lymphocytes might be a lot more flexible than previously thought. New research from the RIKEN Center for Allergy and Immunology (RCAI) in Japan and La Jolla Institute for Allergy and Immunology (LIAI) in the USA shows for the first time that mature CD4+ helper T lymphocytes can be re-programed to become killer-like CD8+ T lymphocytes and gain killing functions.
Willow trees cultivated for 'green energy' can yield up to five times more biofuel if they grow diagonally, compared with those that are allowed to grow naturally up towards the sky.
This effect had been observed in the wild and in plantations around the UK, but scientists were previously unable to explain why some willows produced more biofuel than others.
Now British researchers have identified a genetic trait that causes this effect and is activated in some trees when they sense they are at an angle, such as where they are blown sideways in windy conditions.
Baited black traps in a pyramid shape attract significantly more brown marmorated stink bugs than other traps, according to U.S. Department of Agriculture (USDA) scientists. Evaluating stink bug responses to different visual stimuli may help manufacturers design better traps for monitoring the bugs.
Entomologist Tracy Leskey at the Agricultural Research Service (ARS) Appalachian Fruit Research Station in Kearneysville, W.V., focused on visual stimuli that can attract the stink bugs to traps that will help farmers monitor the level of infestation in their fields and orchards.
In the latest issue of Science, researchers from Lund University in Sweden have shown how nanowires could pave the way for more efficient and cheaper solar cells.
"Our findings are the first to show that it really is possible to use nanowires to manufacture solar cells", says Magnus Borgström, a researcher in semiconductor physics and the principal author.
COUPLES seeking to build a family, and surrogate mothers overseas who help them, are in danger of emotional, physical and financial exploitation unless UK authorities monitor and regulate the field much more closely, according to a University of Huddersfield professor who has published the results of a detailed investigation.
The dwindling reserves of fuelwood in Africa have been illuminated in a new study published today, which shows a bleak outlook for supplies across savannas in South Africa.
Presenting their findings in IOP Publishing's journal Environmental Research Letters, researchers have found that at current consumption levels in the communal areas of Lowveld, South Africa, reserves of fuelwood could be totally exhausted within 13 years.
