Scientists using laser light to detect potential diseases via breath samples, says new study
By blasting a person's breath with laser light, scientists from the National Institute of Standards and Technology and the University of Colorado at Boulder have shown that they can detect molecules that may be markers for diseases like asthma or cancer.   view more (2008-02-19)

Optical 'frequency comb' can detect the breath of disease
Exhale on a cold winter day and you will see the water vapor coming out of your mouth. Light up your breath with a Nobel-Prize-related tool, and you could potentially detect trace amounts of over 1,000 compounds, some of which provide early warning signs of disease.   view more (2008-02-20)

Atomic clock signals may be best shared by fiber-optics
Time and frequency information can be transferred between laboratories or to other users in several ways, often using the Global Positioning System (GPS). But today's best atomic clocks are so accurate—neither gaining nor losing one second in as long as 400 million years—that more... view more (2007-03-05)

Laser light may be able to detect diseases on the breath
A team of scientists at JILA, a joint institute of the National Institute of Standards and Technology (NIST) and the University of Colorado (CU) at Boulder, has shown that by sampling a person's breath with laser light they can detect molecules in the breath that may be markers for diseases like... view more (2008-02-19)

'Frequency comb' spectroscopy proves to be powerful chemical analysis tool
Physicists at JILA have designed and demonstrated a highly sensitive new tool for real-time analysis of the quantity, structure and dynamics of a variety of atoms and molecules simultaneously, even in minuscule gas samples.   view more (2006-03-17)

New 'nano-positioners' may have atomic-scale precision
Engineers have created a tiny motorized positioning device that has twice the dexterity of similar devices being developed for applications that include biological sensors and more compact, powerful computer hard drives.   view more (2008-08-21)

Heads-up study of hair dynamics may lead to better hair-care products
rom frizzy perms to over-bleached waves, "bad hair days" could soon become a less frequent occurrence. Chemists report the first detailed microscopic analysis of what happens to individual hair fibers when they interact with each other, an advance in knowledge key to the development of... view more (2008-08-18)

Prevalence of overactive bladder is overestimated
According to the International Continence Society, overactive bladder is a symptom-defined condition characterized by urinary urgency, with or without urgency incontinence, usually with urinary frequency and nocturia (night-time urination).   view more (2007-02-07)

Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species.   view more (2008-03-06)

Preliminary Study Suggests Endomitriosis Could Contribute To Infertility
Authors of a research letter in this week's issue of THE LANCET provide preliminary evidence which suggests that the peritoneal fluid of women with endometriosis may play a significant role in reducing fertility. Endometriosis and infertility are known to be associated, but it is not known whether... view more (2002-10-16)

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)

Genetic risk factor for common childhood respiratory infection identified
The severity of the common childhood infection, bronchiolitis, may be genetically determined, shows research in Thorax. Bronchiolitis is a respiratory infection which affects nearly all children by their second year. Occurring in winter epidemics, in most cases it is caused by respiratory syncytial... view more (2000-11-16)

Nine Out Of Ten Should Increase Their Consumption Of Fruit And Vegetables In The Eight Nordic And Baltic Countries
The NORBAGREEN 2002 Study examined the consumption frequency of vegetables, fruit and berries, bread and fish in eight Nordic and Baltic countries.

'Laser tweezers' may help the hard of hearing
A University of Sussex neuroscientist has been awarded £775,000 by the Medical Research Council to continue his research into the causes of deafness, by looking at hair cells in the ear. "Hair cells are the sensory receptors in the ear. Sound vibrates the hairs, which produces an... view more (2003-02-05)

Sex unlikely to cause a stroke and may reduce risk of sudden death
Middle aged men should be heartened to know that frequent sex is not likely to increase their risk of stroke. It may actually reduce the risk of sudden death, suggests research in the Journal of Epidemiology and Community Health.   view more (2002-01-15)
