Human Papillomavirus (HPV) Lesion Identified at the Dentist
Human papillomavirus (HPV) is a group of viruses that includes more than 100 different strains or types and is the most common sexually transmitted virus. view more (2009-02-19)
Bottleneck in Blood Supply Makes Brain Vulnerable to Strokes
A team of UC San Diego physicists and neuroscientists has discovered a bottleneck in the network of blood vessels in the brain that makes it vulnerable to strokes. The finding may explain the origin of the puzzling damage to the brain's gray matter often detected in brain scans, especially among the elderly. view more (2007-01-05)
Researchers catch ion channels in their opening act
Each thought or action sends a million electrical signals pulsing through your body. At the heart of the process of generating these electrical impulses is the ion channel. view more (2008-07-11)
Researchers observe single protein dimers wavering between two symmetrically opposed structures
Researchers at The Scripps Research Institute, the University of California, San Diego, and Ohio State University have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the... view more...

DARESBURY REPORT SHOWS ROAD TO CLEANER TRANSPORT
Future global targets on reducing emissions of greenhouse gases may be more easily met thanks to new research on catalysts for fuel cells, published today in the new annual report from Daresbury Laboratory’s Synchrotron Radiation Department. Tough emission targets are driving the development of zero emission vehicles such as electric cars.... view more... (2000-12-11)
An advanced genetic diagnostic method for multiple myeloma
A researcher at the University of Navarra, Borja Sáez Ochoa, has proposed a new genetic diagnostic method for multiple myeloma (MM), a type of bone marrow cancer, which permits the detection of this disease in earlier stages. view more (2006-09-12)
Narrow-band imaging increases specificity of early lung cancer detection
Research published in the September 2009 issue of the Journal of Thoracic Oncology has found that narrow-band imaging bronchoscopy increases the specificity of bronchoscopic early lung cancer detection and can serve as an alternative detection device. view more (2009-09-03)
Raman spectroscopy to undergo a UV transformation - New technique could help rapid detection of infecting organisms in hospitals and prove authenticity of foods such
Researchers at the University of Wales, Aberystwyth (UWA) are about to put ultra-violet Raman spectroscopy through its paces as a new technique for studying biological materials. Dr Roy Goodacre and colleagues in the Institute of Biological Sciences have been awarded a grant worth £306,291 by the Engineering and Physical Sciences Research... view more... (2002-03-01)
NIST researchers 'all aglow' over new test of toxin strength
A new National Institute of Standards and Technology (NIST) assay using a "glow or no glow" technique may soon help the U.S. Department of Homeland Security (DHS) defend the nation against a spectrum of biological weapons that could be used in a terrorist attack. view more (2009-06-18)
A new light on the anti-tumor mechanisms of Scutellaria barbata
Medicinal plants have been used as traditional remedies for hundreds of years. Among them, S. barbata has been traditionally used in treatment of hepatitis, inflammation, osteomyelitis and gynecological diseases in China. view more (2009-01-05)
Novel light-sensitive compounds show promise for cancer therapy
Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells. view more (2009-06-17)
Helicobacter pylori inhibits intercellular communication of cultured gastric cells
The formation of a cancer is proven to be a multi-stage, multi-mechanism process by animal and human studies. As a definite carcinogen, the role of Helicobacter pylori (H pylori) in the formation of gastric cancer has been unclear. view more (2007-10-29)
Yale researchers make cell biology quantitative
Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively. view more (2005-10-20)
How to distinguish between battery and free-range eggs - without visiting the farm
Scientists have developed a method of determining whether eggs labelled as 'free-range' or 'barn' have in fact been laid under battery conditions. The procedure, published in Journal of the Science of Food & Agriculture this month, means eggs can be tested without the need to visit farms. view more (2005-03-31)
Sugar metabolism tracked in living plant tissues, in real time
Scientists at Carnegie's Department of Plant Biology have made the first real-time observations of sugars in the cells of intact and living plant tissues. view more (2006-09-01)
Chromosomal chaos in early embryonic development is linked to abnormalities in cytokinesis and spindle formation
Berlin, Germany: Abnormalities in the spindles (the bi-polar thread like structures that link and pull the chromosomes during cell division) of human embryos before implantation may be the primary reason for many of the chromosome defects observed in early human development, a scientist said on Wednesday 30 June 2004 at the 20th annual conference... view more...

'Shuttling' protein possibly key to resilience of cancer cells
Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease. view more (2006-03-08)
'Micro-boxes' of water used to study single molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules. view more (2006-07-24)
C1XS catches first glimpse of X-ray from the moon
The C1XS X-ray camera, jointly developed by the UK's STFC Rutherford Appleton Laboratory and the Indian Space Research Organisation (ISRO), has successfully detected its first X-ray signature from the Moon. view more (2009-01-26)
A potential drug for liver carcinoma
Looking for efficient anti-tumor drugs is a hot research area. Chrysin (5,7-dihydroxy flavone), a natural widely-distributed flavonoid, has been reported to have many different biological activities such as anti-oxidant, anti-virus, antidiabetogenic activity and clear anxiolytic effect. view more (2009-05-22)
