A study in the September issue of The American Naturalist describes new details about a fungal parasite that coerces ants into dying in just the right spot—one that is ideal for the fungus to grow and reproduce. The study, led David P. Hughes of Harvard University, shows just how precisely the fungus manipulates the behavior of its hapless hosts.
(Santa Barbara, Calif.) –– Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically –– but has up to five levels of energy instead of the usual two. The findings are published in the August 7 issue of Science.
Typical Janus particles consist of miniscule spherical beads that have one hemisphere coated with a magnetic or metallic material. External magnetic or electric fields can then be used to control the orientation of the particles. However, this coating interferes with optical beams, or traps, another tool scientists use to control positioning.
INDIANAPOLIS – A team approach to preventive healthcare delivery for older adults developed by researchers from Indiana University and the Regenstrief Institute improves health and quality of life, decreased emergency department visits and lowered hospital admission rates. By the second year the new model saved money for the sickest (those with three to four chronic diseases), and in the third year, a year after the home-based intervention ended, it saved even more.
FAIRBANKS, ALASKA--Staff from Poker Flat Research Range have traveled north to assist fire personnel in mapping Interior Alaska's Crazy Mountain Complex fires with unmanned aircraft. The team is stationed at Mile 145 of the Steese Highway, between Circle and Central, which are communities near the Yukon River. They have been deploying the aircraft since Aug. 5.
Researchers at the National Physical Laboratory (NPL) in Teddington have developed imaging technology to be used in an intelligent harvesting machine that could minimise wastage and solve an impending labour shortage for UK farmers.
Annual waste for certain crops can be up to 60% - which can mean up to £100,000 of lost revenue for an average farm every year, according to farmers who were consulted during research. Falling number of migrant labourers means that healthy crops cannot be gathered and so farms are losing crops due to harvesting at the wrong time.
SAN FRANCISCO — Middle-aged men who strongly idealize masculinity are almost 50 percent less likely than other men to seek preventative healthcare services, according to a study—the first population-based analysis of men's masculinity beliefs and preventative healthcare compliance—to be presented at the 104th annual meeting of the American Sociological Association.
SAN FRANCISCO — Single parents are more likely than parents in nuclear families to receive financial help from their grown, live-in children, according to research to be presented at the 104th annual meeting of the American Sociological Association.
WEST LAFAYETTE, Ind. - Researchers are developing a new class of tiny mechanical devices containing vibrating, hair-thin structures that could be used to filter electronic signals in cell phones and for other more exotic applications.
CAMBRIDGE, Mass. -- Carbon nanotubes — tiny, rolled-up tubes of graphite — promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the metals used to grow nanotubes react unfavorably with materials found in circuits and composites. But now, researchers at MIT have for the first time shown that nanotubes can grow without a metal catalyst.
