Mechanical Forces Affect T-Cell Functions

April 11, 2014 7:00 am | by Georgia Institute of Technology | News | Comments

T-cells use a complex process to recognize foreign pathogens and diseased cells. Researchers have added a new level of understanding to that process by describing how the T-cell receptors use mechanical contact– the forces involved in their binding to the antigens– to make decisions about whether or not the cells they encounter are threats.


Filter Recovers 80 Percent of Gold in Cell Phone Scrap

April 11, 2014 7:00 am | by VTT Technical Research Centre of Finland | News | Comments

Cell phone scrap can contain precious metals, such as gold and copper. Now, researchers have developed a biological filter, made of mushroom mycelium mats, enabling recovery of as much as 80 percent of the gold in electronic scrap.


Climate Drove Evolution of Ice Age Predators

April 11, 2014 7:00 am | by Natural History Museum of Los Angeles County | Videos | Comments

Researchers, working at the famous La Brea Tar Pits, are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.


Ancestral Grass May Save Modern Wheat

April 11, 2014 7:00 am | by Agricultural Research Service | News | Comments

Scientists have pinpointed the location of a gene in a little-known ancient grass that could help save one of the world's most important cereal crops from an unrelenting fungus.


FDA: Sweetened Honey Isn't Honey

April 11, 2014 7:00 am | by Associated Press, Mary Jalonick | News | Comments

Fruits, Veggies Increase Healthiness Even in Small Amounts

April 11, 2014 7:00 am | by The Conversation, Amanda Avery | News | Comments

Not many people achieve the recommendation of five portions of fruits and vegetables per day – the current average intake is just under four. But, the reduced risk of dying from cancer and heart disease is associated with any increased intake of vegetables and fruit over and above one portion per day. So the more you eat, the more you reduce your risk.

Physicists Announce Inexplicable Particle

April 10, 2014 12:00 pm | by The Conversation, Harry Cliff | News | Comments

Researchers who run one of four large experiments at the Large Hadron Collider have announced one of the most genuinely exciting observations to come out of the 27 km super-collider so far– an exotic particle that cannot be explained by current theories.


Spray Gun Creates Self-assembling Nanoparticle Films

April 10, 2014 12:00 pm | by Texas A&M Univ. | News | Comments

Researchers have developed a simple approach to applying a coating of thin, flat nanoplatelets— using a common spray gun— that spontaneously self-assemble into “nanowalls.” The nanowalls act as rigid barriers that prevent oxygen gas from reaching the surface of objects prone to corrosion.
