New NIST method improves accuracy of spectrometers
Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors. view more (2005-06-17)
Rough scientist wins top physics award
A Sussex scientist has landed a top award from the Institute of Physics for his efforts in promoting physics. The Public Awareness of Physics Award recognises the work of Dr Jonathan Hare from the University of Sussex, who spends much of his time promoting science to the public and schools through lecture tours and a variety of television... view more...

Formation of cellulose fibers tracked for the first time
Cellulose-a fibrous molecule found in all plants-is the most abundant biological material on Earth. view more (2006-04-21)
Growing tiny carbon nanotube wires to connect computer chips of the future
Computers and electronic devices of the future will utilise technologies not currently available. view more (2007-11-26)
Getting more from whole-transcript microarrays
The widely-used Affymetrix Whole-Transcript Gene 1.0 ST (sense target) microarray platform, normally used to assay gene expression, can also be utilized to interrogate exon-specific splicing. view more (2009-05-22)
A new gene silencing platform -- silence is golden
A team of researchers led by Rutgers' Samuel Gunderson has developed a novel gene silencing platform with very significant improvements over existing RNAi approaches. view more (2009-02-09)
Prof develops cancer nanobomb
University of Delaware researchers are opening a new front in the war on cancer, bringing to bear new nanotechnologies for cancer detection and treatment and introducing a unique nanobomb that can literally blow up breast cancer tumors. view more (2005-10-14)
Preschool children display innate skill with numbers, addition
Psychologists at Harvard University have found that five-year-olds are able to grasp numeric abstractions and arithmetic concepts even without the formal education or language to express this knowledge in words. view more (2005-09-20)
Examination of radiation left from birth of universe could alter theories
Using relic radiation from the birth of the universe, astrophysicists at the University of Illinois have proposed a new way of measuring the fine-structure constant in the past, and comparing it with today. view more (2007-04-03)
The benefits of social contact
Have you ever wondered why people surrounded by friends or family appear happier and healthier? view more (2007-05-18)
Detailed echoes from inside the body
In the early days of medical ultrasound, physicians only saw shadowy outlines of the structures inside the body. Today's techniques are not only capable of providing still and moving images of very high resolution. They can be used to measure the rate of blood flow or even discern signs of hardening of the arteries: Where the walls of the blood... view more... (2003-03-11)
Magnetic computer sensors may help study biomolecules
Magnetic switches like those in computers also might be used to manipulate individual strands of DNA for high-speed applications such as gene sequencing, experiments at the National Institute of Standards and Technology (NIST) suggest. view more (2007-05-11)
Iowa State researchers contribute to discovery of gamma rays from starburst galaxy
Iowa State University astrophysicists contributed to the recent discovery that a galaxy quickly creating new stars is also a source of high energy gamma rays. view more (2009-11-03)
Thin films of silicon nanoparticles roll into flexible nanotubes
By depositing nanoparticles onto a charged surface, researchers at the University of Illinois at Urbana-Champaign have crafted nanotubes from silicon that are flexible and nearly as soft as rubber. view more (2005-06-15)
Astronomers report mysterious giant star clusters
An international team of astronomers reported evidence for the formation of mysterious "super star clusters" Jan. 9 at the annual meeting of the American Astronomical Society in Washington, D.C. view more (2006-01-11)
MAGNETIC RESONANCE IMAGING COULD BENEFIT RESIDUAL RECTAL-CANCER MANAGEMENT (pp 495, 497)
The technique of magnetic resonance imaging (MRI) could help clinicians identify patients at high risk of recurrence of rectal cancer, conclude authors of a study in this week's issue of THE LANCET. Incomplete surgical removal of rectal cancer (resulting in the formation of circumferential tumour spread) is thought to be the main cause of local... view more... (2001-02-14)
Reach out and touch an oscillator: Cornell researchers find a new way to read nanoscale vibrations
Nanomechanical oscillators — tiny strips of vibrating silicon only a few hundred atoms thick — are the subject of extensive study by nanotechnology researchers. They could someday replace bulky quartz crystals in electronic circuits or be used to detect and identify bacteria and viruses. view more (2007-03-27)
Generation and regeneration: a scientific media briefing on developmental biology
Might our descendants donate cells at birth which would be stored and grown into bone, skin, blood vessels and cartilage to replace tissues they damaged in accidents? This briefing will discuss how our cells are generated and how much we understand at the moment about regenerating tissues. Embryo development starts with a single cell and ends up... view more...

Genetic testing helps physicians zero in on eye disease
Rapid genetic testing for eye disease is becoming a reality, thanks to a technology developed at the University of Michigan Kellogg Eye Center. view more (2005-09-19)
Researchers mimic lotus leaves for self-cleaning PV arrays, non-stick MEMS
Researchers at the Georgia Institute of Technology are mimicking one of Nature's best non-stick surfaces to help create more reliable electric transmission systems, photovoltaic arrays that retain their efficiency, MEMS structures unaffected by water and improved biocompatible surfaces able to prevent cells from adhering to implanted medical... view more...
