Amsterdam, The Netherlands -- Many consumers want to increase their intake of heart-healthy n-3 fatty acids, found naturally in fish and fish products, but find it difficult to consume the levels recommended by the American Heart Association. Scientists at Virginia Tech have demonstrated that it may be possible to achieve the suggested daily intake in a single serving of a savory-flavored yogurt, providing an easily incorporated dietary source for these valuable fatty acids. Their work is detailed in the April issue of the Journal of Dairy Science®.

In their efforts to render cars and trains more economical, manufacturers are trying to find lighter materials to replace those currently used. But there is a problem: Lighter materials tend not to be as tough as steel or aluminum, so they cannot simply be used in place of these metals. Rather, it is a question of manufacturers deciding which components can really afford to have weight shaved off and how to integrate them into the overall systems.
HOUSTON -- Want a see-through cellphone you can wrap around your wrist? Such a thing may be possible before long, according to Rice University chemist James Tour, whose lab has developed transparent, flexible memories using silicon oxide as the active component.
SAN DIEGO, March 27, 2012 — Amid concerns about possible terrorist attacks with nuclear materials, and fresh memories of environmental contamination from the 2011 Fukushima Daiichi nuclear disaster in Japan, scientists today described development of a capsule that can be dropped into water, milk, fruit juices and other foods to remove more than a dozen radioactive substances.
Where a child lives can greatly affect his or her risk for asthma. According to a new study by scientists at Columbia University, neighborhood differences in rates of childhood asthma may be explained by varying levels of air pollution from trucks and residential heating oil. Results appear online in the Journal of Exposure Science and Environmental Epidemiology.
COLUMBIA, Mo. -- Accusations of racism accompanying the death of Trayvon Martin and the subsequent actions of Florida police are prevalent in the national media this week. Many are questioning the psychological motivations of everyone involved. Recent research by University of Missouri Professor of Psychological Sciences Bruce D. Bartholow has shown that consuming alcohol can lead to increased expression of racial bias.
Ecologists in New Zealand have shown for the first time that Marine Protected Areas – long advocated as a way of protecting threatened marine mammals – actually work. Their study, based on 21 years' monitoring and published today in the British Ecological Society's Journal of Applied Ecology, reveals that a marine sanctuary off the coast of Christchurch has significantly improved survival of Hector's dolphins – one of the rarest dolphins in the world.
Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways of arranging those cells, which are typically placed flat on a rooftop or other surface, or sometimes attached to motorized structures that keep the cells pointed toward the sun as it crosses the sky.
p>Compelling evidence of the impact of the Deepwater Horizon oil spill on deep-sea corals will be published online in the Early Edition of the journal Proceedings of the National Academy of Sciences during the week beginning 26 March 2012. The diverse team of researchers, led by Penn State University Professor of Biology Charles Fisher, used a wide range of underwater vehicles, including the research submarine Alvin, to investigate the corals.
Mixing a little dry ice and a simple industrial process cheaply mass-produces high-quality graphene nanosheets, researchers in South Korea and Case Western Reserve University report.
Graphene, which is made from graphite, the same stuff as "lead" in pencils, has been hailed as the most important synthetic material in a century. Sheets conduct electricity better than copper, heat better than any material known, are harder than diamonds yet stretch.
Study by Haverford College professor reveals unprecedented impact of Deepwater Horizon on deep ocean
Scientists report they have "compelling evidence" that the Deepwater Horizon oil spill has impacted deep-sea corals. Their study, published today in the journal Proceedings of the National Academy of Sciences USA ("Impact of the Deepwater Horizon oil spill on a deep-water coral community in the Gulf of Mexico") utilized a wide range of underwater vehicles, including the submarine Alvin, to investigate the corals and comprehensive two-dimensional gas chromatography to determine precisely the source of petroleum hydrocarbons found.
Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level.
Transistors are the building blocks of the electronic devices that power the digital world, and much of the growth in computing power over the past 40 years has been made possible by increases in the number of transistors that can be packed onto silicon chips.
The production of wind-derived renewable energy is growing, and so, it's important to help wind farm owners operate at higher efficiencies with lower costs.
In fact, figures from the World Wind Energy Association report that installed global capacity for wind-energy production was approximately 240,000 megawatts of power in 2011, up nearly ten fold since 2001.
The hallmark loss of helper CD4+ T cells during human immunodeficiency virus (HIV) infection may be a red herring for therapeutics, according to a study published on March 26th in the Journal of Experimental Medicine.
