Termites repelled by catnip oil

Known for its intoxicating effects on felines, catnip oil may also have a future in termite control. Recent experiments by USDA Forest Service researcher Chris Peterson show that catnip oil repels and even kills termites in a laboratory setting.

Peterson, a researcher with the Forest Service Southern Research Station (SRS), and fellow researcher Janice Ems-Wilson, a chemist at Valencia Community College in Orlando, FL, presented the results of their research at the national meeting of the Am

Argonne researchers use electric field to manipulate tiny particles

Intricate patterns formed by granular materials under the influence of electrostatic fields have scientists at the U.S. Department of Energy’s Argonne National Laboratory dreaming of new ways to create smaller structures for nanotechnologies. With a combination of electric fields and fluid mixtures, researchers Igor Aronson, Maksim Sapozhnikov, Yuri Tolmachev and Wai Kwok can cause tiny spheres of bronze and other metals to self-assemble into crystalline patterns, honeycombs, pulsating rings and

A closer look yields new clues to why bacteria stick to things

A bacterium’s ability to change its hairstyle may help in the effort to clean contaminated groundwater for drinking, according to Penn State researchers.

People are continually moving into places that are hot, sunny and arid where drinking water is in short supply, says R. Kramer Campen, Penn State graduate student in geosciences. “The imperative to find ways to clean groundwater is paramount,” he told attendees today (March 25) at the 225th American Chemical Society national meeting i

Doomed matter near black hole gets second lease on life

Supermassive black holes, notorious for ripping apart and swallowing stars, might also help seed interstellar space with the elements necessary for life, such as hydrogen, carbon, oxygen and iron, scientists say.

Using NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton satellite, scientists at Penn State University and the Massachusetts Institute of Technology found evidence of high-speed winds blowing away copious amounts of gas from the cores of two quasar galaxies, which are

Finnish interface technology for Italian car design

Intelligent environment learns and is technically interactive

VTT, Technical Research Centre of Finland, has developed technology which operates through people’s gestures. The new concept is currently being introduced for research purposes at Italdesign-Giugiaro S. p.a. the Italian car design firm. The same technology is used in wireless terminal equipment user interface research in the Netherlands at the Philips research centre HomeLab.
This VTT technology known as gesture inter

Look into my eyes – The Physics Congress 2003

Eye diseases and circulation problems can now be observed in full colour thanks to the development of a scanning laser ophthalmoscope (SLO) that operates simultaneously with low-power red, green and blue lasers. Dr Ayyakkannu Manivannan will report the latest test results on the SLO at the Institute of Physics Congress at Heriot-Watt University on Tuesday 25 March. He will demonstrate how the SLO system can reveal early retinal damage in diabetic patients and inflammatory macular disease in the elde
