New Technique Identifies Populations Within a Microbial Community Responsible for Biomass Deconstruction
One of the keys to commercialization of advanced biofuels is the development of cost-competitive ways to extract fermentable sugars from lignocellulosic biomass. The use of enzymes from thermophiles – microbes that thrive at extremely high temperatures and alkaline conditions – holds promise for achieving this. Finding the most effective of these microbial enzymes, however, has been a challenge. That challenge has now been met by a collaboration led by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). (more…)
Stunning images of the Andromeda Galaxy are among the first to emerge from a new wide-field camera installed on the enormous Subaru Telescope atop the Hawaiian mountain Mauna Kea. The camera, called the Hyper-Suprime Cam (HSC), is the result of an international collaboration between Princeton University astrophysicists and Japanese and Taiwanese scientists.
With this new camera, researchers will be able to conduct a “cosmic census” of hundreds of millions of galaxies in a wide swath of sky in sufficient depth to probe mysteries such as dark matter and dark energy, while searching for baby galaxies in the early universe. The images of the Andromeda Galaxy demonstrate the new camera’s ability to capture images for a large-scale survey that will help scientists understand the evolutionary history and fate of the expanding universe. The camera’s enormous field of view allowed the entire Andromeda Galaxy, which is some 60,000 light years across, to be captured in a single shot. (more…)
Using neurofeedback techniques, Dr. Judson Brewer of Yale says he can teach people to “see” the subjective experience known to meditators as mindfulness. Brewer explains that too often we trip ourselves up when we get caught up in our own thinking. In the video and accompanying research papers, Brewer and colleagues describe how subjects can […]
A year after NASA’s Mars rover Curiosity’s landed on Mars, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., are testing a sophisticated flight-control algorithm that could allow for even more precise, pinpoint landings of future Martian spacecraft. (more…)
Scientists use tools called gradients to understand how molecules interact in biological systems. Researchers from North Carolina State University have developed a new technique for creating biomolecular gradients that is both simpler than existing techniques and that creates additional surface characteristics that allow scientists to monitor other aspects of molecular behavior.
A gradient is a material that has a specific molecule on its surface, with the concentration of the molecule sloping from a high concentration on one end to a low concentration at the other end. The gradient is used not only to determine whether other molecules interact with the molecules on the gradient, but to determine the threshold level at which any interactions take place. (more…)
A Professor from The University of Manchester has had his name immortalised as a new species of fly.
Professor Richard Preziosi, from the Faculty of Life Sciences, said he was delighted with the unusual tribute from researcher Dr Dave Penney.
It follows his continued support of Dr Penney’s unfunded research into amber rocks which he has been investigating for around 20 years.
Dr Penney discovered the new species of fly, which he has named Proceroplatus preziosii, on the Caribbean island of Hispaniola, after finding a fossil in 16 million-year-old amber from the Dominican Republic. His findings were confirmed by Dr Neal Evenhuis, of the Bishop Museum in Hawaii, who is the leading world expert on this group. The species is a tiny gnat just a few millimetres long belonging to the Keroplatidae family. (more…)
Before the digital age, neuroscientists got their information in the library like the rest of us. But the explosion of neuroscience research has resulted in the publication of nearly 2 million papers — more data than any researcher can read and absorb in a lifetime.
