'Tornadoes' are transferred from light to sodium atoms
For the first time, tornado-like rotational motions have been transferred from light to atoms in a controlled way at the National Institute of Standards and Technology (NIST).   view more (2006-11-10)

Sodium loses its luster: A liquid metal that's not really metallic
When melting sodium at high pressures, the material goes through a transition in which its electrical conductivity drops threefold.   view more (2007-09-27)

In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location.   view more (2007-02-08)

Opening a channel for salt retention
A research team has developed the first small molecule that can reversibly activate a key protein involved in balancing sodium levels, paving the way for drugs that can treat low blood pressure and related conditions.   view more (2008-04-28)

Scientist proposes explanation for puzzling property of night-shining clouds at the edge of space
An explanation for a strange property of noctilucent clouds--thin, wispy clouds hovering at the edge of space at 85 km altitude--has been proposed by an experimental plasma physicist at the California Institute of Technology (Caltech), possibly laying to rest a decades-long mystery.   view more (2008-09-26)

COLONOSCOPY DANGER? (p 282)
Physicians should monitor blood sodium concentrations in patients developing long-term psychological or neurological symptoms after colonoscopy, report the authors of a research letter published in this week's issue of THE LANCET. After observing an unusual case of colonoscopy-induced hyponatraemic... view more (2001-01-24)

Low-sodium advice for asthmatics should be taken with a pinch of salt
Following a low-sodium diet does not appear to have any appreciable impact on asthma control, according to new research.   view more (2008-07-16)

Combination treatment for migraine more effective than single medications
Combining two different types of treatment for migraine results in better symptom relief than taking either one of the medications, according to a study in the April 4 issue of JAMA.   view more (2007-04-04)

Protein's potential as a regulator of brain activity discovered
UC Irvine researchers have found that a protein best known for building connections between nerve cells and muscle also plays a role in controlling brain cell activity.   view more (2006-04-21)

Understanding and diagnosing an inherited pain syndrome
Yale School of Medicine researchers report the first demonstration that a single mutation in a human sodium channel gene can trigger pain in people with an inherited pain syndrome known as primary erythromelalgia, according to a study published this month in the journal Brain.   view more (2005-07-14)

Sodium hydration therapies equally effective
In patients undergoing cardiac catheterization, contrast dye injection can sometimes cause contrast-induced nephropathy (CIN), otherwise known as acute renal failure.   view more (2007-03-27)

American Physiological Society
A new study concludes that low birthweight babies born with low sodium (salt) in their blood serum will likely consume large quantities of dietary sodium later in life.   view more (2007-01-19)

Super atoms turn the periodic table upside down
Researchers at Delft University of Technology (TU Delft) in The Netherlands have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) behave in the same way as individual... view more (2008-07-01)

Serum sodium predicts mortality 10 times higher in PAH patients
Patients with pulmonary arterial hypertension (PAH)-chronically high blood pressure in the blood vessels of the lungs-whose serum sodium levels are low (called hyponatremia, or HN) have a very poor chance of survival and a high rate of right-heart failure (RHF), according to new research from the... view more (2008-06-13)

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)

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)

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)

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... view more (2007-11-28)

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... 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... 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)

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... view more (2004-04-13)
