Convergent evolution of molecules in electric fish
Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin. view more (2006-03-06)
Lowering sodium consumption could save US $18 billion annually in health costs, study finds
Reducing Americans' average intake of sodium to the amount recommended by health officials could save the nation as much as $18 billion annually in avoided health care costs and improve the quality of life for millions of people, according to a new RAND Corporation study. view more (2009-09-14)
First observation of linkage between genes controlling resistance found in crop pests
Researchers at Clemson University, USA have found connections between resistance controlling genes in Heliothis virescens F (Tobacco budworm), a serious pest of cotton. `This linkage may contribute to the rapid evolution of resistance observed in this pest` said researcher Thomas M Brown. view more (2002-01-30)
Early treatment of macular degeneration with macugen may help patients preserve their vision
Age-related macular degeneration (AMD) is the leading cause of blindness in older patients in the developed world. view more (2005-10-07)
How does sodium phosphate combined with bisacodyl affect small intestine?
Capsule endoscopy is a well accepted tool for evaluation of small bowel pathologies (e.g., bleeding sources). However, it has some limitations due to restricted recording time and reduced visibility by air and residual material. view more (2008-05-21)
Research suggests vegetable juice may help people with metabolic syndrome lose weight
Drinking at least one glass of low sodium vegetable juice daily may help overweight people with metabolic syndrome achieve better weight loss results. view more (2009-04-20)
NIST announces first observation of 'persistent flow' in a gas
Using laser light to stir an ultracold gas of atoms, researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (NIST/University of Maryland) have demonstrated the first "persistent" current in an ultracold atomic gas -a frictionless flow of particles. view more (2007-11-28)
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)

Why white light is best for our town centres
White lighting is twice as good at letting you see the face of someone else as that from the yellow light from high pressure sodium lamps commonly used to light our streets, according to new research sponsored by the ESRC and published as part of Social Science week. It can therefore allow the same facial recognition as conventional sodium... view more... (2004-06-22)
The salt of life and genes
Mineral salts are essential for living organisms. To be precise, it is from these, living cells get their basic components, the ions. Common salt, for example, contains chloride and sodium ions which the cell uses to establish and maintain electrochemical balance with the environment. In order to achieve sodium equilibrium in animal cells, for... view more... (2003-04-16)
Preserved in crystal
Scientists at the Weizmann Institute of Science recently discovered a new source of well-preserved ancient DNA in fossil bones. view more (2006-02-03)
Ultrafast lasers take 'snapshots' as atoms collide
Using laser pulses that last just 70 femtoseconds (quadrillionths of a second), physicists have observed in greater detail than ever before what happens when atoms collide. view more (2005-10-21)
Help your kidneys: Pass on salt and diet soda
Individuals who consume a diet high in sodium or artificially sweetened drinks are more likely to experience a decline in kidney function, according to two papers being presented at the American Society of Nephrology's annual meeting in San Diego, California. view more (2009-11-02)
Could seaweed clean up DDT?
Adding small amounts of seaweed to contaminated soil could prove to be a natural and effective way of breaking down the toxic pesticide DDT, according to new research in the Journal of Chemical Technology and Biotechnology. A British biologist, Ian Singleton, worked with colleagues in Australia and Thailand to find the right formula to use. Too... view more... (2004-04-13)
Drug treats 'water intoxication' faster, more effectively
Results of the two largest studies on hyponatremia, SALT-1 and SALT-2, presented Nov. 14 at the American Heart Association's Scientific Sessions in Chicago, found that the investigational drug tolvaptan treated hyponatremia - water intoxication - faster and more effectively than available treatments. view more (2006-11-15)
Patient safety advanced by revised heparin standards
Continuing to help ensure the identity, purity and quality of heparin, the U.S. Pharmacopeial (USP) Convention has revised written and physical standards for the widely used blood thinner. view more (2009-07-31)
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)
Alzheimer's-associated enzyme can disrupt neural activity in the brain
An enzyme involved in the formation of the amyloid-beta protein associated with Alzheimer's disease can also alter the mechanism by which signals are transmitted between brain cells, the disruption of which can cause seizures. view more (2007-06-18)
Atom 'noise' may help design quantum computers
As if building a computer out of rubidium atoms and laser beams weren't difficult enough, scientists sometimes have to work as if blindfolded: The quirks of quantum physics can cause correlations between the atoms to fade from view at crucial times. view more (2007-03-05)
