Solving Puzzle-Like Bond for Biofuels: First Look at One of Nature's Strongest Biomolecular InteractionsMarch 17, 2015 3:02 pm | by Texas Advanced Computing Center | News | Comments
One of life's strongest bonds has been discovered by a science team researching biofuels with the help of supercomputers. Their find could boost efforts to develop catalysts for biofuel production from non-food waste plants. Renowned computational biologist Klaus Schulten of the University of Illinois at Urbana-Champaign led the analysis and modeling of the bond, which behaves like a Chinese Finger Trap puzzle.

Researchers have cracked a code that governs infections by a major group of viruses, including the common cold and polio. The unnoticed code had been hidden in plain sight in the sequence of the ribonucleic acid (RNA) that makes up this type of viral genome. But researchers have unlocked its meaning and demonstrated that jamming the code can disrupt virus assembly. Stopping a virus assembling can stop it functioning.
Quantum chemical calculations have been used to solve big mysteries in space. Soon the same calculations may be used to produce tomorrow’s cancer drugs. Quantum chemical calculations are needed to explain what happens to the electrons’ trajectories within a molecule, and the results of a quantum chemical calculation are often more accurate than what is achievable experimentally.
By analyzing the light of hundreds of thousands of celestial objects, astronomers have created a unique map of enigmatic molecules in our galaxy that are responsible for puzzling features in the light from stars, called diffuse interstellar bands. DIBs have been a mystery ever since they were discovered in 1922 — exactly which of the many thousands of possible molecules are responsible for these features?
Russia's richest man says he has bought James D. Watson's Nobel Prize medal at Christie's in order to return it to the scientist. The 1962 Nobel Prize in Physiology or Medicine was awarded jointly to Francis Harry Compton Crick, James Dewey Watson and Maurice Hugh Frederick Wilkins "for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material."
Biological engineers have created a new computer model that allows them to design the most complex three-dimensional DNA shapes ever produced, including rings, bowls, and geometric structures such as icosahedrons that resemble viral particles.
Van der Waals forces act like a sort of quantum glue on all types of matter. Using a new measuring technique, scientists from Forschungszentrum Jülich experimentally determined for the first time all of the key details of how strongly the single molecules bind to a surface. With an atomic force microscope, they demonstrated that the forces do not just increase with molecular size, but that they even grow disproportionately fast.
Researchers at Ohio State University Cancer Comprehensive Care Center developed and implemented bioinformatics and molecular methods to understand what happens to human papillomavirus (HPV) DNA in the "end game" of HPV-positive human cancers.
A team of computer scientists working to improve how researchers across the sciences empower big data to solve problems have been awarded $5 million by the National Science Foundation. The team will address one of the leading challenges in tackling some of the world’s most pressing issues in science: the ability to analyze and compute large amounts of data.
Scientists have used computer simulations to show how bacteria are able to destroy antibiotics — a breakthrough that will help develop drugs which can effectively tackle infections in the future. Researchers at the University of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it from working, making the bacteria resistant.
Computationally intensive research in Sweden will soon get a boost from the fastest academic supercomputer in the Nordic countries, to be installed in October 2014 at KTH Royal Institute of Technology. KTH is due to begin using the fastest academic supercomputer of any university in Scandinavia. A Cray XC30 with 1,676 nodes and a memory of 104.7 terabytes will be installed at KTH’s PDC Center for High Performance Computing.
IBM announced that Caris Life Sciences is using IBM technical computing and storage technology to accelerate the company’s molecular profiling services for cancer patients. The Caris tumor profiling database is one of the largest datasets in the application of advanced molecular profiling technologies to support clinicians in delivering personalized treatment recommendations — or precision oncology.

It all begins in the brain as a flood, tens of millions of neurotransmitters handed off from one neuron to another in just a fraction of a second. Memories, dreams and learning share a common thread in this exchange of electrical and chemical signals by the nearly 100 billion spindly neurons of the brain, each cell networked to 10,000 others.
SDSC Joins Intel Parallel Computing Centers Program with Focus on Molecular Dynamics, Neuroscience and Life SciencesSeptember 12, 2014 2:44 pm | by San Diego Supercomputer Center | News | Comments
The San Diego Supercomputer Center (SDSC) at the University of California, San Diego, is working with semiconductor chipmaker Intel to further optimize research software to improve the parallelism, efficiency, and scalability of widely used molecular and neurological simulation technologies.
Every trillionth of a second, Panagiotis Grammatikopoulos calculates the location of each individual atom in a particle based on where it is and which forces apply. He uses a computer program to make the calculations, and then animates the motion of the atoms using visualization software. The resulting animation illuminates what happens, atom-by-atom, when two nanoparticles collide.
