A 100-year-old physics problem has been solved

At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought. The discovery has implications in telecommunications. Working around ...

Finding aliens may be even easier than previously thought

Finding examples of intelligent life other than our own in the Universe is hard work. Between spending decades listening to space for signs of radio traffic – which is what the good people at the SETI Institute have been ...

Study unravels long-held Fermi puzzle tied to nonlinear systems

In physics, the Fermi-Pasta-Ulam-Tsingou (FPUT) problem—which found that certain nonlinear systems do not disperse their energy, but rather return to their initial excited states—has been a challenge that scientists have ...

Researchers report reversal of current flow in a quantum system

In a classical thermodynamic system, heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one. The same thing happens in quantum systems, but this state can be changed, ...

Chinese researchers develop new battery technology

A Chinese research team has developed a novel, environmentally friendly, low-cost battery that overcomes many of the problems of lithium ion batteries (LIB). The new aluminum-graphite, dual-ion battery (AGDIB) offers significantly ...
