Analysis finds strong match between molecular, fossil data in evolutionary studies
During a seminar at another institution several years ago, University of Chicago paleontologist David Jablonski fielded a hostile question: Why bother classifying organisms according to their physical appearance, let alone analyze their evolutionary dynamics, when molecular techniques had already invalidated that approach? view more (2009-04-29)
Professor Eero Vuorio to chair the EMBL Council
Professor Eero Vuorio has been elected to chair the Council of the European Molecular Biology Laboratory (EMBL) in 2003. His predecessor Professor Peter Gruss has assumed office as President of the Max-Planck Society. Professor Vuorio is Professor in Molecular Biology at the University of Turku, Finland, and Chair of the Research Council for... view more... (2002-11-29)
Tuberculosis Diagnostics Within Several Minutes
A single glance at the patient's blood plasma will now be sufficient to ascertain whether he/she is ill with tuberculosis, and should the diagnosis be unfavourable - to determine the stage of the disease. Certainly, the plasma will be viewed through the device developed by the specialists of the Sechenov Moscow Medical Academy and their colleagues... view more... (2004-12-10)
New tumor markers determine therapy intensity
Characteristic changes in the DNA of medulloblastoma, the most frequent malignant brain tumor in childhood, indicate precisely how aggressively the tumor will continue to spread and what the chances of disease relapse are. view more (2009-03-18)
Genetics behind developmental brain disorders may play a wider role with congenital diseases
Findings of a recent genetic study on developmental brain disorders may be the "tip of an iceberg" revealing factors involved with a number of congenital diseases, according to UC Irvine researchers. view more (2006-07-07)
Scientists create custom 3-dimensional structures with 'DNA origami'
By combining the art of origami with nanotechnology, Dana-Farber Cancer Institute researchers have folded sheets of DNA into multilayered objects with dimensions thousands of times smaller than the thickness of a human hair. view more (2009-05-21)
Sight for sore eyes
An inventive breakthrough from the Applied Optics Group at the University of Kent at Canterbury (UKC) is set to revolutionise current methods of eye examinations. Professor David Jackson, Dr Adrian Podoleanu and Dr John Rogers, who gained his doctorate at Kent, have developed an instrument known as an Optical Dual Channel Tomograph. The instrument... view more... (2002-03-13)
Scripps scientists develop first examples of RNA that replicates itself indefinitely
Findings could inform biochemical questions about how life began. Now, a pair of Scripps Research Institute scientists has taken a significant step toward answering that question. The scientists have synthesized for the first time RNA enzymes that can replicate themselves without the help of any proteins or other cellular components, and the... view more... (2009-01-12)
Scientists develop new blood test for heart disease - New test will be cheap, less invasive, and could take only minutes
Scientists from Imperial College London and the University of Cambridge have developed a rapid new blood test which may help predict the likelihood of a heart attack. The research published in Nature Medicine shows how a new science, developed in the Imperial College laboratories, called Metabonomics, can be used to test for coronary artery... view more...

NMR advance relies on microscopic detector
Detecting the molecular structure of a tiny protein using nuclear magnetic resonance (NMR) currently requires two things: a million-dollar machine the size of a massive SUV, and a large sample of the protein under study. view more (2007-05-16)
A virtual atlas of breast histopathology: An application of web based virtual microscopy
Researchers at the universities of Helsinki and Tampere (Finland) have developed a new virtual microscopy system, which allows users digitize entire microscope glass slide specimens, and then create a virtual slide with the quality and resolution similar to the original glass slide viewed on a microscope. The results are high-resolution digital... view more... (2004-11-26)
Novel biomarker for prediction of survival in colorectal carcinomas revealed
Levels of a protein called thymidylate synthase (TS) within two separate compartments of a tumor cell-the nucleus and the cytoplasm-may be critical markers predicting survival in colorectal cancer, according to a study at Yale University School of Medicine. view more (2006-09-14)
Innovations needed to monitor kidney health
Doctor Harry Holthöfer, M.D., Ph.D, at the University of Helsinki, Finland, coordinates a new EU-funded project, which aims to develop new diagnostic approaches for early identification of patients at high risk of rapid loss of kidney function. view more (2006-05-26)
A better way to copy DNA
Scientists have developed a new method for DNA amplification that could replace the polymerase chain reaction (PCR), a technique that is invaluable for both medical diagnostics and basic research but which is confined to the laboratory. In the August issue of EMBO reports, Huimin Kong and colleagues at New England Biolabs (Beverly, MA, USA)... view more... (2004-07-14)
Molds for Molecules
Molecular imprints in polymers as reaction vessels for pharmaceuticals research Materials with the tiniest of cavities, which can take up other molecules as "guests", play a meaningful role in science and technology. A particularly interesting process for the synthesis of materials with precisely fitted cavities is known as molecular imprinting.... view more... (2002-11-28)
Science Matters in Northern Ireland
SBS today welcomed the opening of the new Centre for Molecular Biosciences at the University of Ulster, but highlighted the general lack of government investment in science in Northern Ireland. In a talk to scientists in Northern Ireland, Dr Peter Cotgreave, Director of SBS, pointed out that overall government investment in the science base is... view more... (2002-02-01)
Less expensive anti-clotting medication appears as safe and effective as more expensive treatment
Subcutaneous (beneath the skin) injection of the original and less expensive form of the anticoagulant medication heparin is as effective and safe as subcutaneous administration of the newer and more expensive low-molecular-weight heparin for treatment of venous thromboembolism (blood clots in the deep veins of the legs or in the lungs). view more (2006-08-23)
Gene chip data improved therapy in some patients with incurable cancer
Like many oncologists, Eric P. Lester, M.D., was faced with a dilemma: seven patients with advanced, incurable cancer, an arsenal of drugs that may or may not help them, and not enough solid proof about treatment efficacy to guide him. view more (2007-09-20)
HYPER-CEST MRI Breaks New Ground in Molecular Imaging
Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have developed a new technique for Magnetic Resonance Imaging (MRI) that allows detection of signals from molecules present at 10,000 times lower concentrations than conventional MRI techniques. view more (2006-10-23)
The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping. view more (2007-07-27)
