Model offers new understanding of cell signaling
Looking for answers in the bright light of day, rather than the confined beam of a street light at night. That's how University of Michigan researcher Sofia Merajver, M.D., Ph.D., describes the power of a new mathematical model that could have far-reaching impact on how scientists study cellular signaling pathways. view more (2008-03-25)
MIT reveals the tangle under turbulence
Picture the flow of water over a rock. At very low speeds, the water looks like a smooth sheet skimming the rock's surface. As the water rushes faster, the flow turns into turbulent, roiling whitewater that can overturn your raft. view more (2007-03-29)
Scientists synthesize memory in yeast cells
Harvard Medical School researchers have successfully synthesized a DNA-based memory loop in yeast cells, findings that mark a significant step forward in the emerging field of synthetic biology. view more (2007-09-17)
Prediction of RNA pseudoknots using heuristic modeling with mapping and sequential folding
An algorithm utilizing structure mapping and thermodynamics is introduced for RNA pseudoknot prediction. The method finds the minimum free energy in the context of the biological folding direction (5' to 3') of RNA sequences. view more (2007-09-19)
New possibilities for drug design
An article in Journal of Physics B, published on 7 July 2003 by the Institute of Physics, reports on a new technique which could in future help scientists working in rational drug design (a way of tailoring a new drug to fit the structure of the protein it targets) to develop drugs more efficiently. The work, which was on a molecule called... view more... (2003-07-04)
Researchers Find That Superman's Teeth Can Superconduct
Researchers at the University of Warwick have found that phosphorus, an element commonly found in teeth, can act as a "superconductor" - but you would have to have the strength of Superman to clench your teeth hard enough for it to work - as it happens at a pressure of around 2.5 megabars - some 30,000 times harder than an ordinary human... view more...

New Research Demonstrates That Social Interaction Determines Left Or Right-side Bias
Why aren't left and right-handers equally common? New research* demonstrates that the prevalence of bias or handedness in one direction (Lateralisation) is likely to result from social selection pressures, rather than mere evolutionary chance or genetics. The research is published in Proceedings B, a learned journal published by The Royal Society.... view more... (2004-03-02)
Joint research into an enzyme that causes genetic diseases
Researchers from CIC bioGUNE's Structural Biology Unit and Columbia University (New York) have conducted a joint research project, published in the prestigious scientific journal Structure, to gain in-depth knowledge of the structure of pyruvate carboxylase when it is in solution (in the "natural" state). view more (2009-08-06)
Mathematics might save you a trip to the ER
Since the days of Hippocrates, people have known that certain illnesses come and go with the seasons. More recently, researchers have learned that these cyclic recurrences of disease, known as seasonality, are often related to the weather. view more (2007-09-13)
TANGO - towards faster prognosis of Alzheimer's and Parkinson's diseases?
A large number of diseases - including Alzheimer's disease, Parkinson's disease, and mad cow disease - are the result of proteins that erroneously assume the wrong shape, causing them to stick to each other. This phenomenon is perceptible, but up to now it has been difficult to predict. Researchers from the Flanders Interuniversity Institute for... view more... (2004-09-13)

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)
Researchers solve first structure of a key to intact DNA inheritance
Researchers have solved the structure of a DNA-protein complex that is crucial in the spread of antibiotic resistance among bacteria. Knowing this structure also provides fundamental insight into how cells successfully divide into two new cells with intact DNA. view more (2007-12-21)
An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
University of Alberta researchers unravel intricate animal patterns
There is a scene in the animated blockbuster "Finding Nemo" when a school of fish makes a rapid string of complicated patterns—an arrow, a portrait of young Nemo and other intricate designs. view more (2007-04-17)
The Lancet Oncology
CLEAR SKIES NOT SO CLEAN This months Leading Edge editorial examines the recently published US Environmental Protection Agency`s (EPA) 10-year in-the-making report on the toxic effects of diesel exhaust fumes from large vehicles. The report-which showed that large cities are heavily polluted with emissions that are associated with increased risk... view more... (2002-10-02)
Warbling Whales Speak a Language All Their Own
The songs of the humpback whale are among the most complex in the animal kingdom. Researchers have now mathematically confirmed that whales have their own syntax that uses sound units to build phrases that can be combined to form songs that last for hours. view more (2006-03-22)
Mathematical analysis techniques for the study of epilepsy
Dr. Elena Urrestarazu has employed a mathematical technique, known as Independent Components Analysis, in order to separate brain activities of different origins. In her PhD, defended at the Faculty of Medicine of the University of Navarre, Dr. Urrestarazu demonstrated that this technique could be applied brain registers in humans. view more (2004-11-12)
