Researchers have developed a statistical method for genetic screens that improves the classic genome-wide association screen, and, applying to autism, have uncovered genes related to the disorder that had not been suggested in previous analyses. The scientists offer evidence that beginning treatment in infants at the first symptoms could change the course of the disease, possibly preventing the permanent “pruning” of neurons, which occurs during the first two years of life, from cementing autistic symptoms in place.
Your memory is a wily time traveler, plucking fragments of the present and inserting them into the past, reports a new study. In terms of accuracy, it's no video camera. Rather, memory rewrites the past with current information, updating your recollections with new experiences to aid survival. Love at first sight, for example, is more likely a trick of your memory than a Hollywood-worthy moment.
Scientists have demonstrated broadband terahertz wave generation using metamaterials. The discovery may help develop noninvasive imaging and sensing, and make possible terahertz-speed information communication, processing and storage.
Scientists have demonstrated in mice what could be a revolutionary new technique to cure a wide range of human diseases -- from cystic fibrosis to cataracts to Alzheimer's disease -- that are caused by "misfolded" protein molecules.
Copper adorns the Statue of Liberty, makes sturdy, affordable wiring, and helps our bodies absorb iron. Now, researchers at Duke University would like to use copper to transform sunlight and water into a chemical fuel.
The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: Scientists have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.
"Supercapacitors" take the energy-storing abilities of capacitors (which store electrical charge that can be quickly dumped to power devices) a step further, storing a far greater charge in a much smaller package.
A team of scientists from the National University of Singapore (NUS) has successfully developed a method to chemically exfoliate molybdenum disulfide crystals, a class of chalcogenide compounds, into high quality monolayer flakes, with higher yield...
All good research breaks new ground, but rarely does the research unearth truths that challenge the foundation of a science. That's what chemists have now done. Scientists have compressed sodium chloride -- rock salt -- to form new compounds.
Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide underground -- and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches.
