Some 15 percent of adults suffer from fertility problems, many of these due to genetic factors. This is something of a paradox: We might expect such genes, which reduce an individual's ability to reproduce, to disappear from the population. Recent research may have solved the riddle. Not only can it explain the high rates of male fertility problems, it may open new avenues in understanding the causes of genetic diseases and their treatment.
The following first appeared as a guest post by Nicholas Taylor, Web Archiving Service Manager for Stanford University Libraries. The Internet Archive Wayback Machine has been mentioned in several news articles within the last week for having archived a since-deleted blog post from a Ukrainian separatist leader touting his shooting down a military transport plane which may have actually been Malaysia Airlines Flight 17.
Using Powerful GPU-Based Monte Carlo Simulation Engine to Model Larger Systems, Reduce Data Errors, Improve System PrototypingJuly 22, 2014 8:33 am | by Jeffrey Potoff and Loren Schwiebert | Blogs | Comments
Recently, our research work got a shot in the arm because Wayne State University was the recipient of a complete high-performance compute cluster donated by Silicon Mechanics as part of its 3rd Annual Research Cluster Grant competition. The new HPC cluster gives us some state-of-the-art hardware, which will enhance the development of what we’ve been working on — a novel GPU-Optimized Monte Carlo simulation engine for molecular systems.
Physicists have created a unique combination of computer models, based on the theory of quantum mechanics, and applied them to a previously well-characterized protein found in muscle to develop a new picture of how biomolecules transport and store oxygen (O2). In doing so, the team has shown how the process of respiration, which is fundamental in humans and other vertebrates, exploits quantum mechanical effects working on tiny scales.
Over the years, computer chips have gotten smaller, thanks to advances in materials science and manufacturing technologies. This march of progress, the doubling of transistors on a microprocessor roughly every two years, is called Moore’s Law. But there’s one component of the chip-making process in need of an overhaul if Moore’s law is to continue: the chemical mixture called photoresist.
An international team of scientists has discovered that vampire bat venom contains molecules capable of evading the victim’s immune system. The results point to entirely new forms of anticoagulants in the venom, as well as novel molecules that cause dilation of the small arteries near the skin.
The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.
Cellphone metadata has been in the news quite a bit lately, but the National Security Agency isn’t the only organization that collects information about people’s online behavior. Newly downloaded cellphone apps routinely ask to access your location information, your address book or other apps and, of course, Web sites like Amazon or Netflix track your browsing history in the interest of making personalized recommendations.
This 200x photo of brain cancer stem cells from human brain cancer tissue received an Image of Distinction designation in the 2013 Nikon Small World Photomicrophotography Competition, which recognizes excellence in photography with the optical microscope. It was taken using immunofluorescence.
Core ELN (electronic lab notebook) is a chemistry application for Platform for Science that is designed to help chemists document research activities and compound registration in the cloud. It is made possible through Platform for Science’s Platform-as-a-Service (sPaaS).
SLAS is a global organization that provides forums for education and information exchange to encourage study and professional collaboration aimed at advancing laboratory science and technology for the drug discovery, biotechnology, chemical, data informatics, clinical diagnostic, consumer product, pharmaceutical, and other industries.
In nearly every field of science, experiments, instruments, observations, sensors, simulations, and surveys are generating massive data volumes that grow at exponential rates. Discoverable, shareable data enables collaboration and supports repurposing for new discoveries — and for cross-disciplinary research enabled by exchange across communities that include both scientists and citizens.
Tandem protein mass spectrometry is one of the most widely used methods in proteomics, the large-scale study of proteins, particularly their structures and functions. Researchers in the Marcotte group at the University of Texas at Austin are using the Stampede supercomputer to develop and test computer algorithms that let them more accurately and efficiently interpret proteomics mass spectrometry data.
The Program Committee has announced a call for papers for the Pittcon 2015 Technical Program. Abstracts are currently being accepted for contributed oral and poster presentations in areas such as, but not limited to, analytical chemistry, applied spectroscopy, life science, bioanalysis, food science, nanotechnology, environmental science and pharmaceutical. The 2015 committee is especially interested in topics relevant to energy and fuels.
Discovering a brain tumor is a very serious issue, but it is not the end of the story. There are many different types of brain tumor with different survival rates and different methods for treatment. However, today, many brain tumors are difficult to clearly diagnose, leading to poor prognoses for patients.

Supercomputer simulations have shown that clusters of a protein linked to cancer warp cell membranes. This research on these protein clusters, or aggregates as scientists call them, could help guide design of new anticancer drugs.
Researchers at The University of Tennessee are a step closer to creating a prophylactic drug that would neutralize the deadly effects of the chemical weapons used in Syria and elsewhere. Jeremy Smith, UT-ORNL Governor’s Chair and an expert in computational biology, is part of the team that is trying to engineer enzymes — called bioscavengers — so they work more efficiently against chemical weapons.
Researchers have discovered seven new species of chirping giant pill-millipedes. The species discovered all belong to the genus Sphaeromimus, which is Latin for 'small ball animal.' However, the designation 'small' is not always true for members of the genus, as one of the newly discovered species surprises with a size larger than a ping-pong ball. Another special characteristic is the largest chirping organs of any millipede.
Every day thousands of people around the world have their lives saved or improved thanks to someone giving blood. But imagine how many more lives could be saved if a long-lasting blood substitute could be found, which could easily be stored at room temperature and available to all patients, regardless of their blood type. This is the challenge a team of scientists at the University of Essex are hoping to overcome with their Haem02 project
Computer systems today can be found in nearly all areas of life, from smartphones to smart cars to self-organized production facilities. These systems supply rapidly growing data volumes, and computer science now faces the challenge of processing these huge amounts of data (big data) in a reasonable and secure manner.
