Chandra independently determines Hubble constant
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory. view more (2006-08-10)
UCSB researchers describe breakthrough in the quantum control of light
Researchers at UC Santa Barbara have recently demonstrated a breakthrough in the quantum control of photons, the energy quanta of light. view more (2009-05-29)
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)
NASA gets a 3-D look at Neki becoming extra-tropical
NASA's Aqua and Tropical Rainfall Measuring Mission (TRMM) satellites are watching Tropical Storm Neki become extra-tropical, and TRMM data was used to create a three-dimensional image of the storm. view more (2009-10-27)
Paving The Way To A Greener Future & Healthy Economy
Converting crushed glass collected from bottle banks into attractive outdoor floor tiles is one of the innovative research projects being undertaken by a specialist Staffordshire University team. The work is being conducted by the internationally recognised Ceramic Technology Group based within the University's School of Engineering and Advanced... view more... (2001-10-09)
Visual assistance for cosmic blind spots
A bit of imagination on the part of a measuring instrument wouldn't be a bad thing. It could help to add data from areas where the instrument is unable to measure. view more (2009-11-24)
Precise picture of early Universe supports 'dark matter' theory
A detailed picture of the seeds of structures in the universe has been unveiled by an international team co-led by a Cardiff University scientist. view more (2009-11-03)
Magnetic field research could make computers 500 times more powerful
Magnetic fields created using nanotechnology could make computers up to 500 times more powerful, if new research is successful. view more (2006-06-23)
Optical atomic clock becomes portable
You imagine a clock to be different - yet the optical table with its many complicated set-ups really is one. Optical clocks like the strontium clock in the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig could be the atomic clocks of the future; some of them though are already ten times more precise and stable than the best primary... view more...

Hurricane Katrina: Phone Home
Though New Orleans residents were told to evacuate days before the arrival of Hurricane Katrina, no one could have predicted the real extent of the devastation. view more (2009-07-07)
Optical Atomic Clock: A long look at the captured atoms
Optical clocks might become the atomic clocks of the future. Their "pendulum", i.e. the regular oscillation process which each clock needs, is an oscillation in the range of the visible light. view more (2008-02-06)
VLT Observations Confirm that the Universe Was Hotter in the Past
UVES Measures the Cosmic Temperature 12 Billion Years Ago Summary A fundamental prediction of the Big Bang theory has finally been verified. For the first time, an actual measurement has been made of the temperature of the cosmic microwave background radiation, at a time when the Universe was only about 2.5 billion years old. This fundamental and... view more... (2000-12-19)
Researchers say Arctic sea ice still at risk despite cold winter
Using the latest satellite observations, NASA researchers and others report that the Arctic is still on "thin ice" when it comes to the condition of sea ice cover in the region. A colder-than-average winter in some regions of the Arctic this year has yielded an increase in the area of new sea ice, while the older sea ice that lasts for... view more... (2008-03-19)
ESA and EADS-CASA sign contract to build instrument for the SMOS mission
A significant milestone in the development of ESA's Soil Moisture and Ocean Salinity (SMOS) mission was reached last week when the contract to build the payload was signed between ESA and EADS (European Aeronautic Defence and Space Company)-CASA from Spain. The contract, worth 62 million euros, was signed in Madrid, Spain on 11 June 2004 at the... view more... (2004-06-17)
European light research opens door for optical storage and computing
The goal of replacing electronics with optics for processing data in computers is coming closer through cutting edge European research into the mysterious properties of "fast and slow" light. view more (2008-04-25)
'Conversation stoppers' fight deadly bacterial infections
Bacterial infections are becoming more deadly worldwide due to increased resistance to antibiotics. Now, chemists at the University of Wisconsin-Madison have developed a powerful strategy to fight these deadly infections: Instead of killing the bacteria directly, the scientists designed a group of compounds that can block the chemical signals that... view more...

Active optical clock
Institute of Quantum Electronics, School of Electronics Engineering and Computer Science, Peking University, has proposed the concept, principles and techniques of active optical clock. view more (2009-04-13)
Cosmologists predict a static universe in 3 trillion years
When Dutch astronomer Willem de Sitter proposed a static model of the universe in the early 1900s, he was some 3 trillion years ahead of his time. view more (2007-05-24)
NASA finds Greenland snow melting hit record high in high places
A new NASA-supported study reports that 2007 marked an overall rise in the melting trend over the entire Greenland ice sheet and, remarkably, melting in high-altitude areas was greater than ever at 150 percent more than average. In fact, the amount of snow that has melted this year over Greenland could cover the surface size of the U.S. more than... view more... (2007-09-26)
Caltech scientists create nanoscale zipper cavity that responds to single photons of light
Physicists at the California Institute of Technology (Caltech) have developed a nanoscale device that can be used for force detection, optical communication, and more. view more (2009-06-08)
