Scientists keeping tabs on big breakers with radar

Scientists of the Geesthacht GKSS Research Centre have developed a radar system with which it is possible to study the behaviour of sea waves. This technology will be used immediately on the North Sea on the FINO3 research platform in order to determine the interactions between offshore wind power machines and swells.

Discovery to aid study of biological structures, molecules

Discovery to aid study of biological structures, molecules

WEST LAFAYETTE, Ind. - Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures.

The researchers demonstrated their new understanding of how the instrument - the atomic force microscope - works in water to show detailed properties of a bacterial membrane and a virus called Phi29, said Arvind Raman, a Purdue professor of mechanical engineering.

Experiments at UCSB push quantum mechanics to higher levels

Experiments at UCSB push quantum mechanics to higher levels

(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.

Capping Janus particle gives engineers complete control

Capping Janus particle gives engineers complete control

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.

ADA publishes practice guidelines for nutrition care for patients with spinal cord injury

CHICAGO – The American Dietetic Association has published new evidence-based nutrition practice guidelines for registered dietitians on nutrition care for patients with spinal cord injury.

The guidelines contain systematically developed recommendations to assist practitioners in appropriate nutrition care, with specific recommendations on:

Satellites unlock secret to northern India's vanishing water

Using NASA satellite data, scientists have found that groundwater levels in northern India have been declining by as much as one foot per year over the past decade. Researchers concluded the loss is almost entirely due to human activity.

More than 26 cubic miles of groundwater disappeared from aquifers in areas of Haryana, Punjab, Rajasthan and the nation's capitol territory of Delhi, between 2002 and 2008. This is enough water to fill Lake Mead, the largest manmade reservoir in the United States, three times.

Satellites unlock secret to Northern India's vanishing water: human consumption

Irvine, Calif. – Using satellite data, UC Irvine and NASA hydrologists have found that groundwater beneath northern India has been receding by as much as 1 foot per year over the past decade – and they believe human consumption is almost entirely to blame.

More than 109 cubic kilometers (26 cubic miles) of groundwater disappeared from the region's aquifers between 2002 and 2008 – double the capacity of India's largest surface-water reservoir, the Upper Wainganga, and triple that of Lake Mead, the largest manmade reservoir in the U.S.

Carnitine supplements reverse glucose intolerance in animals

DURHAM, N.C. – Supplementing obese rats with the nutrient carnitine helps the animals to clear the extra sugar in their blood, something they had trouble doing on their own, researchers at Duke University Medical Center report.

A team led by Deborah Muoio (Moo-ee-oo), Ph.D., of the Duke Sarah W. Stedman Nutrition and Metabolism Center, also performed tests on human muscle cells that showed supplementing with carnitine might help older people with prediabetes, diabetes, and other disorders that make glucose (sugar) metabolism difficult.

Parasite causes zombie ants to die in an ideal spot

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.
