New research has identified some of the processes by which molecules associated with neurological diseases can disrupt the biological clock, interfere with sleep and activity patterns and set the stage for a spiral of health concerns that can include a decreased lifespan and Alzheimer’s disease.
Traditionally, to understand how a gene functions, a scientist would breed an organism that lacks that gene, “knocking it out”, then ask how the organism has changed. Are its senses affected? Its behavior? Can it even survive? Thanks to the recent advance of gene editing technology, this gold standard genetic experiment has become much more accessible in a wide variety of organisms.
HIV can establish itself in the brain as soon as four months after initial infection; a finding that dampens hopes of an impending cure for a disease that afflicts more than 35 million people. Within two years of infection, a genetically distinct version of HIV replicates in the brains of as many as one in four patients.
A new study led by Scripps Institution of Oceanography at the Univ. of California, San Diego, researchers has revealed that the thickness of Antarctica’s floating ice shelves has recently decreased by as much as 18% in certain areas over nearly two decades, providing new insights on how the Antarctic ice sheet is responding to climate change.
Nanoparticles are specifically adapted to the particular application by Small Molecule Surface Modification. Thereby surfaces of work pieces or moldings are expected to exhibit several different functions at one and the same time. Fabricators and processors alike demand consistently high quality for their intermediate and final products. The properties of these goods usually also have to meet specific requirements.
In a recent study published in Physical Review Letters, the research group led by ICREA Prof. at ICFO Morgan Mitchell has detected, for the first time, entanglement among individual photon pairs in a beam of squeezed light. Quantum entanglement is always related to the microscopic world, but it also has striking macroscopic effects, such as the squeezing of light or superconductivity.
Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn't cancer usually requires a biopsy to study cells directly. Now results of a Johns Hopkins Univ. study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells.
Big data: It's a term we read and hear about often, but is hard to grasp. Computer scientists at Washington Univ. in St. Louis tackled some big data about an important protein and discovered its connection in human history as well as clues about its role in complex neurological diseases.
Researchers have made an experimental breakthrough in explaining a rare property of an exotic magnetic material, potentially opening a path to a host of new technologies. From information storage to magnetic refrigeration, many of tomorrow's most promising innovations rely on sophisticated magnetic materials, and this discovery opens the door to harnessing the physics that governs those materials.
Studies confirm that IT investments in companies improve productivity and efficiency. Univ. of Michigan professor M.S. Krishnan wondered if the same was true for government. After all, IT spending could either lead to efficiency or create bureaucratic bloat.
Chemists from Brown Univ. have found a way to make new 2-D, graphene-like semiconducting nanomaterials using an old standby of the semiconductor world: silicon. In a paper published in Nanoletters, the researchers describe methods for making nanoribbons and nanoplates from a compound called silicon telluride. The materials are pure, p-type semiconductors that could be used in a variety of electronic and optical devices.
Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA's Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results, published in Science, show that dark matter interacts with itself even less than previously thought, and narrows down the options for what this mysterious substance might be.
Taking our understanding of quantum matter to new levels, scientists at Los Alamos National Laboratory are exposing high-temperature superconductors to very high magnetic fields, changing the temperature at which the materials become perfectly conducting and revealing unique properties of these substances.
Deep below the ice, far from the playful penguins and other animals that bring tourists to Antarctica, is a cold and barren world that by all indications should be completely void of life. But recently, scientists researching melting ice watched a half-foot-long (15-cm) fish swim by. Not long after that, they saw shrimp-like creatures.
In a broad new assessment of the status and prospects of solar photovoltaic technology, Massachusetts Institute of Technology researchers say that it is “one of the few renewable, low-carbon resources with both the scalability and the technological maturity to meet ever-growing global demand for electricity.”
