Light reveals breast tumor oxygen status
Light directed at a breast tumor through a needle can provide pathologists with biological specifics of the tumor and help oncologists choose treatment options that would be most effective for that individual patient. view more (2009-04-01)
Disappearing vowels 'caught' on tape in US midwest
Try to pronounce the words "caught" and "cot." If you're a New Yorker by birth, the two words will sound as different as their spellings. But if you grew up in California, you probably pronounce them identically. view more (2009-10-27)
UCLA researchers examine human embryonic stem cell genome
Stem cell researchers from UCLA used a high resolution technique to examine the genome, or total DNA content, of a pair of human embryonic stem cell lines and found that while both lines could form neurons, the lines had differences in the numbers of certain genes that could control such things as individual traits and disease susceptibility. view more (2008-03-28)
Fingerprints provide crucial clue to new nanofiber fabrication technique
Fingerprints are usually used to identify people but, this time, they gave Penn State chemical engineers the crucial clue needed to discover an easy, versatile new method for making nanofibers that have potential uses in advanced filtration as well as wound care, drug delivery, bioassays and other medical applications. view more (2006-01-27)
Research could help finger more criminals
Scientists at the University of Sunderland are working on new technology that could help police forces catch criminals, by providing more clear and detailed fingerprints. Researchers at the university's School of Health, Natural & Social Sciences are developing what's known as a nanoparticle suspension, which could be a major breakthrough for... view more...

Biometric sensors no dirtier than doorknobs, study finds
While biometric equipment is gaining popularity in a variety of applications, such as ensuring secure access to buildings, industries are finding that many users believe the devices are unsanitary and a potential source of germs that could cause illness. view more (2007-10-11)
Finding trapped miners
University of Utah scientists devised a new way to find miners trapped by cave-ins. The method involves installing iron plates and sledgehammers at regular intervals inside mines, and sensitive listening devices on the ground overhead. view more (2009-03-26)
Scientists identify genomic 'fingerprint' for alcohol-induced heart failure
A person with dilated cardiomyopathy has an enlarged and stretched heart cavity, usually too weak to pump normally; most people will go on to develop heart failure. view more (2008-05-05)
NIST issues call for a new 'hash' algorithm
The National Institute of Standards and Technology (NIST) has opened a competition to develop a new cryptographic "hash" algorithm, a tool that converts a file, message or block of data to a short "fingerprint" for use in digital signatures, message authentication and other computer security applications. view more (2007-11-09)
An inner 'fingerprint' for personalizing medical care
Fingerprints move over. Scientists are reporting evidence that people have another defining trait that may distinguish each of the 6.7 billion humans on Earth from one another almost as surely as the arches, loops, and whorls on their fingertips. view more (2009-07-23)
`Glowing` technique could detect river pollution
New technology used to analyse dissolved organic matter in river water could also help scientists detect and monitor pollution, according to a new research published in the journal Hydrological Processes (1). Dissolved organic matter is found in all river water, and can come from both a natural source such as the soil, as well as human sources... view more... (2002-10-07)
Protein expression holds promise for head and neck cancer detection
The blood of patients with head and neck cancer appears to have unique patterns of protein expression that one day could serve as a screening test for the highly aggressive cancer that is often diagnosed too late, researchers say. view more (2006-05-11)
Sleeping sickness finding could lead to earlier diagnosis
Sleeping sickness creates a metabolic 'fingerprint' in the blood and urine, which could enable a new test to be developed to diagnose the disease, according to new research published today in the journal Proceedings of the National Academy of Sciences. view more (2008-04-15)
A fast diagnosis for bacterial meningitis
University of Sydney researchers at Westmead Millennium Institute develop an accurate and rapid method of diagnosing bacterial meningitis. view more (2005-11-17)
Researchers identify cells that make relapse inevitable in acute lymphoblastic leukemia
In "Dr Jekyll and Mr Hyde" Robert Louis Stevenson wrote about the good and evil sides of the same person; now scientists in Australia have discovered that in acute lymphoblastic leukaemia (ALL) there are Dr Jekyll and Mr Hyde cells - "good" and "evil" clones of the same type of ALL cell. view more (2006-11-09)
Bacteria change 'fingerprints' and baffle detectives
Tracing the source of a campylobacter food poisoning outbreak can be very difficult even with modern DNA fingerprinting methods. There is now evidence that campylobacters can rearrange their DNA, disguising their fingerprint, and confusing such detective work, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for... view more...

Protein marker for schizophrenia risk
A protein found in immune cells may be a reliable marker for schizophrenia risk, report researchers in a new proteomics study appearing in the July issue of Molecular and Cellular proteomics. view more (2008-07-09)
Research into lost marine life helps Iran
Research at the University of Bradford is helping Iran's Government in a US$130m claim that the 1991 Gulf War damaged its fisheries industry. Iran is making the claim to the United Nations that oil, which spilled into Persian Gulf sea following the Iraqi invasion of Kuwait, has affected its fish stocks and marine life. The University's Department... view more... (2003-11-12)
What are the predominant bacilli in the intestines ducklings infected with S. enteritidis?
The enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) method has been used to fingerprint the kinetics of microbial community of fecal samples of ducklings orally infected with S. enteritidis. view more (2008-03-13)
Researchers identify new leprosy bacterium
A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology. view more (2008-11-25)
