ERS-1 : Nine-year success story comes to an end
The most exciting results from the ERS-1 mission have been in the field of SAR interferometry, where for the first time precise topographic information could be routinely produced from space data. The ERS-1 and ERS-2 tandem operations demonstrated this technique for various applications and paved the way for the definition of new dedicated SAR... view more... (2000-03-14)
Tandem ions may lead the way to better atomic clocks
Physicists at the Commerce Department's National Institute of Standards and Technology (NIST) have used the natural oscillations of two different types of charged atoms, or ions, confined together in a single trap, to produce the "ticks" that may power a future atomic clock. view more (2005-07-29)
Paying peanuts for clean water
Peanut husks, one of the biggest food industry waste products, could be used to extract environmentally damaging copper ions from waste water, according to researchers in Turkey. view more (2007-11-08)
Saved by junk DNA
VIB researchers linked to K.U.Leuven and Harvard University show that stretches of DNA previously believed to be useless 'junk' DNA play a vital role in the evolution of our genome. view more (2009-05-29)
NIST demonstrates better memory with quantum computer bits
Physicists at the National Institute of Standards and Technology (NIST) have used charged atoms (ions) to demonstrate a quantum physics version of computer memory lasting longer than 10 seconds-more than 100,000 times longer than in previous experiments on the same ions. view more (2005-08-11)
Classifying molar pregnancy
Researchers from The Johns Hopkins Medical Institutions have used short tandem repeat (STR) genotyping and p57 immunohistochemistry to distinguish hydatidiform moles. view more (2009-10-21)
Compound removes radioactive material from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium. view more (2008-03-13)
Metal hazard from table wines
Potentially hazardous levels of metal ions are present in many commercially available wines. An analysis of reported levels of metals in wines from sixteen different countries, published in the open access Chemistry Central Journal, found that only those from Argentina, Brazil and Italy did not pose a potential health risk owing to metals. view more (2008-10-30)
Scientists discover how nanocluster contaminants increase risk of spreading
For almost half a century, scientists have struggled with plutonium contamination spreading further in groundwater than expected, increasing the risk of sickness in humans and animals. view more (2008-04-18)
Topical Papers in Biochemical Journal - Selective determination of mitochandrial chelatable iron in viable cells with a new fluorescent sensor
This paper by Petrat and colleagues marks an important advance in our understanding of the regulation of iron in the human body. Real-time changes in the concentration of the ionized form of iron (Fe2+) can now be monitored within the mitochondria of living cells for the first time, thanks to the technique described in this article. For some... view more... (2002-02-08)
Lighter gas reduces damage to optics in extreme ultraviolet lithography
Researchers at the University of Illinois have discovered a way to generate light and reduce damage in a leading candidate for next-generation microelectronics lithography. The technique could help pack more power into smaller computer chips. view more (2007-09-13)
A Penny for Your Prions
North Carolina State University researchers have discovered a link between copper and the normal functioning of prion proteins, which are associated with transmissible spongiform encephalopathy diseases such as Cruetzfeldt-Jakob in humans or "mad cow" disease in cattle. view more (2009-06-26)
Study could help target new pancreatitis treatments
Pancreatitis is often a fatal condition, in which the pancreas digests itself and surrounding tissue. view more (2009-06-30)
Yale researchers find environmental toxins disruptive to hearing in mammals
Yale School of Medicine researchers have new data showing chloride ions are critical to hearing in mammals, which builds on previous research showing a chemical used to keep barnacles off boats might disrupt the balance of these ions in ear cells. view more (2006-04-12)
The man from Southampton-he says yes!
23 October 1998 How do farmers know when their tomatoes are perfect and just right for picking? Southampton researchers have harnessed the same technology used to print T-shirts to develop a simple, robust device that can be used in the field to indicate when fruit is ripe. John Atkinson, head of the University of Southampton's Thick Film Unit... view more... (1998-11-17)
Higher efficiency organic solar cell created by UCSB Nobel Laureate and research team
Using plastics to harvest the energy of the sun just got a significant boost in efficiency thanks to a discovery made at the Center for Polymers and Organic Solids at the University of California, Santa Barbara. view more (2007-07-13)
X marks the spot: Ions coldly go through NIST trap junction
Physicists at the National Institute of Standards and Technology (NIST) have demonstrated a new ion trap that enables ions to go through an intersection while keeping their cool. view more (2009-04-09)
Journal of Alzheimer's Disease is devoted to metal ions and neurodegenerative diseases
The recent issue of the Journal of Alzheimer's Disease (Volume 8, Issue 2) published by IOS Press is devoted to "Metal Ions and Neurodegenerative Diseases" and presents a collection of important papers dedicated to uncovering the role of various metals in human neurophysiology and neurodegenerative disorders. view more (2006-01-13)
Uncharged organic molecule can bind negatively charged ions
Indiana University Bloomington chemists have designed an organic molecule that binds negatively charged ions, a feat they hope will lead to the development of a whole new molecular toolbox for biologists, chemists and medical researchers who want to remove chlorine, fluorine and other negatively charged ions from their solutions. view more (2008-02-27)
Fragranced Candles Pack A Killer Punch
In recent years the consumer market for candles has grown dramatically, as candles of all shapes, sizes, colours and fragrances have been used increasingly in homes and restaurants to create atmosphere and enhance mood. Now two researchers at the University of Southampton have taken the potential uses of fragranced candles one step further, by... view more... (2004-06-17)
