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)
Economical and cleaner cars with lean-burn catalytic converter
Dutch researcher Karen Scholz has taken a careful look at the properties of a new type of catalytic converter found in cars. view more (2007-07-13)
Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Early detection of lung cancer: New data presented at multidisciplinary meeting
New data from several studies evaluating new techniques for early diagnosis and treatment of lung cancer are being presented at the first European Multidisciplinary Conference on Thoracic Oncology (EMCTO) in Lugano, Switzerland (1-3 May 2009). view more (2009-05-04)
Health: Improving the recognition of brain tumours
Researchers at the Institute of Nuclear Chemistry in Jülich have developed a short-lived, radioactive amino acid that delivers much more precise information on brain tumours and their structure than was possible in the past. By combining positron emission tomography (PET), a process that visualises the spread of radioactive substances in the... view more... (2005-05-04)
The Future is"¦Green
The first green accounts for a public sector body are published today. view more (2004-09-01)
New Research Turns Sewage Farms into Power Plants
Researchers at the University of Warwick's Warwick Process Technology Group have devised a process that turns wet waste from sewage farms and paper mills into a source of power. University of Warwick researcher Dr Ashok Bhattacharya and his team are part of a Europe wide consortium that have cracked the problem of how to extract very pure levels... view more... (2002-04-29)
DNA-wrapped carbon nanotubes serve as sensors in living cells
Single-walled carbon nanotubes wrapped with DNA can be placed inside living cells and detect trace amounts of harmful contaminants using near infrared light. view more (2006-01-27)
Cold storage solution for global warming?
Researchers from the University of Leicester and the British Geological Society (BGS) have proposed storing CO2 in huge underground reservoirs as a way of reducing emissions- and have even identified sites in Western Europe that would be suitable. view more (2007-02-07)
Asphalt flows from deep-sea volcanoes
New kind of volcano discovered in the Gulf of Mexico Underwater volcanoes that spew asphalt instead of lava: they were discovered in the Gulf of Mexico during an expedition of the research vessel SONNE, led by Prof. Gerhard Bohrmann of the DFG Research Center Ocean Margins. On these volcanoes the multinational team of scientists encountered a... view more... (2004-05-17)
Novel nano-etched cavity makes leds 7 times brighter
Researchers at the National Institute of Standards and Technology (NIST) have made semiconductor light-emitting diodes (LEDs) more than seven times brighter by etching nanoscale grooves in a surrounding cavity to guide scattered light in one direction. view more (2006-07-24)
Tracing ultra-fine dust
Fine particle emissions have been the subject of heated debate for years. People who live near industrial plants see the smoke being discharged into the atmosphere and wonder how harmful it is. view more (2009-10-06)
NIST method may help optimize light-emitting semiconductors
Physicists at JILA have demonstrated an ultrafast laser technique for "seeing" once-hidden electronic behavior in semiconductors, which eventually could be useful in more predictable design of optoelectronic devices, including semiconductor lasers and white light-emitting diodes. view more (2006-02-17)
Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands
Permafrost - the perpetually frozen foundation of North America - isn't so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. view more (2007-08-10)
Ancient Oak Trees Help Reduce Global Warming, MU Study Finds
The battle to reduce carbon emissions is at the heart of many eco-friendly efforts, and researchers from the University of Missouri have discovered that nature has been lending a hand. Researchers at the Missouri Tree Ring Laboratory in the Department of Forestry discovered that trees submerged in freshwater aquatic systems store carbon for... view more... (2008-06-30)
Gassed by gannets!
This is one of the subjects being investigated in the GANE (Global Atmospheric Nitrogen Enrichment) research initiative funded by NERC. The first meeting of the principal investigators will be on Thursday, 9th March, when they will share information on progress of the various projects that form the initiative. view more (2000-03-08)
Air pollution from ships - a serious threat
Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the shores. Air pollution from ships may be twice as bad as... view more... (2004-03-30)
Television just got brighter: UCLA engineers are obsessed with the next generation of LEDs
Two researchers at the UCLA Henry Samueli School of Engineering and Applied Science want to make sure future generations of plasma TV watchers will see games like the upcoming NBA Finals in the brightest, most beautiful color possible - for a lot less money. view more (2007-05-17)
New plasma transistor could create sharper displays
By integrating a solid-state electron emitter and a microcavity plasma device, researchers at the University of Illinois have created a plasma transistor that could be used to make lighter, less expensive and higher resolution flat-panel displays. view more (2009-02-05)
