XMM-Newton reveals a tumbling neutron star
Using data from ESA's XMM-Newton X-ray observatory, an international group of astrophysicists discovered that one spinning neutron star doesn't appear to be the stable rotator scientists would expect. view more (2006-04-20)
Hoverflies stripe off in summer heat
Ecologists are unraveling the reasons behind seasonal differences in insects’ colour patterns, a question that has puzzled them since the 1970s. Speaking at the British Ecological Society’s Winter Meeting, to be held at the University of Warwick on 18–20 December 2001, Anne Halpin and Dr Graham Holloway of the University of... view more...

Cool plasma packs heat against biofilms
Though it looks like a tiny purple blowtorch, a pencil-sized plume of plasma on the tip of a small probe remains at room temperature as it swiftly dismantles tough bacterial colonies deep inside a human tooth. view more (2009-06-11)
Old glass - a new material
Insulation materials used for sound insulation, as thermal cladding and in fire prevention play an important role in modern building. Ever since asbestos and a number of other building materials were identified as hazardous, demand has continually grown for non-fibrous building materials that do not present any risk to health. Researchers at the... view more... (1999-09-03)

Coral reef fish harbor an unexpectedly high biodiversity of parasites
IRD researchers showed that Epinephilus maculates, a fairly abundant species of grouper off New Caledonia, was parasitized by 12 species of microscopic monogenean worms. view more (2007-09-06)
Rare cell prevents rampant brain activity
One of the mysteries of the brain is how it avoids ending up in a state of chaos, something which happens only on exceptional occasions, when it can lead to epileptic fits. Scientists at Karolinska Institutet have now uncovered a new mechanism controlling how the brain keeps its neuronal activity in check. view more (2007-03-05)
Quantized heat conduction by photons observed
In a recent experiment, to be published in Nature on November 9, Dr Matthias Meschke and professor Jukka Pekola, together with Dr Wiebke Guichard, a coworker from French CNRS, investigated heat exchange between two small pieces of normal metal, connected to each other only via superconducting leads. The results demonstrate that at very low... view more... (2006-11-10)
Instants In The Flow - Request Stop
The Novosibirsk researchers have developed a device capable of producing mist with support from the Russian Foundation for Basic Research and the Foundation for Assistance to Small Innovative Enterprises (FASIE). The precise name of the device is "field device for measuring liquid and gas velocities". It helps to perform prompt, precise... view more... (2005-02-14)
Clemson physicist addresses international forum on thermoelectric energy
Energy lost from hot engines could save billions of dollars if it could be captured and converted into electricity via thermoelectric devices, Clemson University physicist Terry Tritt told scientists gathered in Dallas for the world-renowned NanoTX '07 conference. view more (2007-10-04)

Toxic substances when cooking fats and oils?
Consumers' food health and safety may be affected by the presence of micro-organisms and toxic substances in foodstuffs. The cause of the presence of toxic substances in food is sometimes due to the fact that these have been subject to processes of degradation. The oxidation or thermal degradation of food lipids causes deterioration in foodstuffs... view more... (2005-05-25)
A QUIET DRILL
The household and industrial heaters as well as glass and metal annealing furnaces are made of ordinary ceramics stand temperature difference poorly - the furnaces would crack as an common facetted glass where fiercely boiling water was pored in. That is why the annealing furnaces have to be heated and cooled gradually and insensibly. It takes... view more... (2003-04-25)

World Record Plasma Discharge in Tore Supra
On July 30th 2002, the engineers and scientists of the Association Euratom-CEA in Cadarache (France) have achieved a three and a half minutes long plasma discharge on Tore Supra, sustained by 3MW of current drive power, thus requiring to exhaust more than 600 Megajoules of thermal energy during the experiment. It establishes a new world record in... view more... (2002-08-02)
