From Europa to the lab, a new recipe for oxygen on icy moons
A new Pacific Northwest National Laboratory study offers the most detailed picture to date on how oxygen can be made in frigid reaches far from Earth. view more (2006-03-28)
'Fishy' clue helps establish how proteins evolve
Three billion years ago, a "new" amino acid was added to the alphabet of 20 that commonly make up proteins in organisms today. Now researchers at Yale and the University of Tokyo have demonstrated how this rare amino acid - and, by example, other amino acids - made its way into the menu for protein synthesis. view more (2009-01-28)
Ocean's journey towards the center of the Earth
A Monash geoscientist and a team of international researchers have discovered the existence of an ocean floor was destroyed 50 to 20 million years ago, proving that New Caledonia and New Zealand are geographically connected. view more (2009-03-05)
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)
New technique can be breakthrough for early cancer diagnosis
Early detection of disease is often critical to how successful treatment can be. Therefore, the development of new methods of diagnosis is a hot research field, where every small step is of great importance. In an article in the latest issue of Molecular & Cellular Proteomics, Uppsala University researchers describe a technique that the... view more... (2007-09-12)
Climate-related changes on the Antarctic peninsula
Scientists have long established that the Antarctic Peninsula is one of the most rapidly warming spots on Earth. view more (2009-03-17)
Pathway links inflammation, angiogenesis and breast cancer
A well-known inflammatory protein spawns an enzyme that inactivates two tumor-suppressing genes, ultimately triggering production of new blood vessels to nourish breast cancer cells. view more (2007-08-10)
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)
CSHL scientists discover new details of a gene-regulatory network governing metabolism
Metabolism is a central feature of life - a myriad of biochemical processes that, together, enable organisms to nourish and sustain themselves. Scientists at Cold Spring Harbor Laboratory (CSHL) are in the forefront of efforts to demonstrate how the regulation of genes governs fundamental life processes, including metabolism. view more (2008-02-25)
Molecular studies in cancer of the colon
According to Dr. Jesús García-Foncillas, Director of the Department of Oncology at the University Hospital (University of Navarra), molecular studies in cancer of the colon will contribute to the establishment of more efficient and less toxic treatments. view more (2005-10-24)
Molecular fossils uncover link between viruses and the immune system
Researchers from the Viikki Biocenter, University of Helsinki, show that atomic structures can reveal evolutionary history of viruses in a similar fashion as fossils did for the dinosaurs and reptiles. Their article is published in the April 15 issue of Molecular Cell. view more (2005-04-14)
Argonne scientists develop techniques for creating molecular movies
They may never win an Oscar, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory have developed techniques for creating accurate movies of biological and chemical molecules, a feat only theorized up until now. view more (2008-04-16)
Scientists stop colon cancer growth in mice by blocking just one enzyme
In cell culture experiments, scientists from the University of Texas Medical Branch at Galveston (UTMB) and the University of Texas at Arlington determined that stopping the activity of a single enzyme called aldose reductase could shut down the toxic network of biochemical signals that promotes inflammation and colon cancer cell growth. view more (2006-10-02)
£17.5m Research Boost for University of Ulster
The University of Ulster today revealed details of an unprecedented £17.5m investment for research which will fund two exciting new world class facilities at its Coleraine and Magee College campuses. The two projects which have received funding under the DFHETE’s SPUR (Support Programme for University Research) are: The Centre for... view more... (2000-12-18)
UCLA researchers outline the structure of the largest non-virus particle ever crystallized
Researchers at UCLA, the California NanoSystems Institute, the David Geffen School of Medicine, and the Howard Hughes Medical Institute have modeled the structure of the largest cellular structure ever crystallized, suggesting ways to engineer the particles for drug delivery. view more (2007-11-27)
Protein plays unexpected role protecting chromosome tips
A protein specialist that opens the genomic door for DNA repair and gene expression also turns out to be a multi-tasking workhorse that protects the tips of chromosomes and dabbles in a protein-destruction complex, a team lead by researchers at The University of Texas M. D. Anderson Cancer Center reports in the Aug. 13 edition of Molecular Cell. view more (2009-08-14)
Test for Dioxin Sensitivity in Wildlife Could Result from New Study
Why are chickens so sensitive to dioxins, but terns seem much more resistant, despite their exposure through eating dioxin-tainted fish? The life-or-death difference researchers have found can be partially explained by two amino acids in the chain of 858 amino acids that form one critical protein. view more (2006-05-19)
