(Phys.org)—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or "superlubricity," was known to exist only on the nanoscale. Then in 2012, scientists first demonstrated superlubricity beyond the nanoscale when they discovered the phenomenon in micrometer-sized graphite. Building on this and related research, scientists in a new study have now theoretically shown that superlow friction could extend to lengths of tens of centimeters.

Researchers at the Moscow Institute of Physics and Technology (MIPT) report that genetically engineered fibers of the protein spidroin has proven to be a perfect substrate for cultivating heart tissue cells.

MIT researchers have developed a new, ultrasensitive magnetic-field detector that is 1,000 times more energy-efficient than its predecessors. It could lead to miniaturized, battery-powered devices for medical and materials imaging, contraband detection, and even geological exploration.

DNA is made from four nucleosides, each known by its own letter -- A, G, C, and T. However, since the structure of DNA was deciphered in 1953, scientists have discovered several other variants that are often added to the DNA sequences to replace one of the usual four letters.

An international research group led by scientists at the National Institute of Standards and Technology's (NIST) Center for Nanoscale Science and Technology has developed a method for measuring crystal vibrations in graphene. Understanding these vibrations is a critical step toward controlling future technologies based on graphene, a one-atom thick form of carbon.

(Phys.org)—Currently, up to 75% of the energy generated by a car's engine is lost as waste heat. In theory, some of this waste heat can be converted into electricity using thermoelectric devices, although so far the efficiency of these devices has been too low to enable widespread commercialization.

A team of bioengineers at Brigham and Women's Hospital (BWH), led by Ali Khademhosseini, PhD, and Nasim Annabi, PhD, of the Biomedical Engineering Division, has developed a new protein-based gel that, when exposed to light, mimics many of the properties of elastic tissue, such as skin and blood vessels. In a paper published in Advanced Functional Materials, the research team reports on the new material's key properties, many of which can be finely tuned, and on the results of using the material in preclinical models of wound healing.

Solar power and other sources of renewable energy can help combat global warming but they have a drawback: they don't produce energy as predictably as plants powered by oil, coal or natural gas. Solar panels only produce electricity when the sun is shining, and wind turbines are only productive when the wind is brisk.

A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.

Neuroscientists have found that a gene mutation that arose more than half a million years ago may be key to humans' unique ability to produce and understand speech.

(Phys.org)—Researchers have designed and implemented an algorithm that solves computing problems using a strategy inspired by the way that an amoeba branches out to obtain resources. The new algorithm, called AmoebaSAT, can solve the satisfiability (SAT) problem—a difficult optimization problem with many practical applications—using orders of magnitude fewer steps than the number of steps required by one of the fastest conventional algorithms.

A therapy combining salmon fibrin injections into the spinal cord and injections of a gene inhibitor into the brain restored voluntary motor function impaired by spinal cord injury, scientists at UC Irvine’s Reeve-Irvine Research Center have found.

At very low temperatures and under strong magnetic fields, thin films of semiconducting materials can display a phenomenon known as the quantum Hall (QH) effect, which can allow electrons to flow with no energy loss. In a newly discovered class of materials known as topological insulators, the same state can be achieved without an external magnetic field, spurring interest in the development of low-power electronics and other promising applications.
