The physics of better batteries

(From phys.org) Harvard University researchers are using physics to solve one of the biggest challenges in designing light-weight, long-lasting batteries: how to squeeze more energy into less space. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Department of Physics have developed a tunable, electrochemical system that can…

Quantum Effect

Quantum effects observed in photosynthesis

(From phys.org) Molecules that are involved in photosynthesis exhibit the same quantum effects as non-living matter, concludes an international team of scientists including University of Groningen theoretical physicist Thomas la Cour Jansen. This is the first time that quantum mechanical behavior was proven to exist in biological systems that are involved in photosynthesis. The interpretation…

Can Facebook be trusted with your personal info? Voter harvesting scheme shows perils for users

Can Facebook be trusted with your personal information? That’s the question many Americans are asking after revelations that a data-mining firm working for the Trump campaign improperly got its hands on the personal information of tens of millions of Facebook users and created detailed profiles that were used to target unsuspecting voters in the presidential…

Neutrons help demystify multiferroic materials

Materials used in electronic devices are typically chosen because they possess either special magnetic or special electrical properties. However, an international team of researchers using neutron scattering recently identified a rare material that has both. In their paper published in Advanced Materials, the team, including researchers from the Department of Energy’s (DOE’s) Oak Ridge National…
