Moiré patterns facilitate discovery of novel insulating phases

Materials having excess electrons are typically conductors. However, moiré patterns—interference patterns that typically arise when one object with a repetitive pattern is placed over another with a similar pattern—can ...

Signs of burnout can be detected in sweat

EPFL engineers, working in association with startup Xsensio, have developed a wearable system that can continually measure the concentration of cortisol—the stress hormone—in human sweat. Their device can eventually help ...

Solvation-driven electrochemical actuation

In a new study led by Institute Professor Maurizio Porfiri at NYU Tandon, researchers showed a novel principle of actuation—to transform electrical energy into motion. This actuation mechanism is based on solvation, the ...

Physicists discover new physical effect

Scientists have found that a perpendicular magnetic field makes electrically neutral quasiparticles (excitons) in semiconductors behave like electrons in the Hall effect. This discovery will help researchers to study the ...

Long-range energy transport in perovskite nanocrystal films

Producing clean energy and reducing the power consumption of illumination and personal devices are key challenges to reduce the impact of modern civilization on the environment. As a result, the surging demand for solar cells ...

RNA molecules are masters of their own destiny

At any given moment in the human body, in about 30 trillion cells, DNA is being "read" into molecules of messenger RNA, the intermediary step between DNA and proteins, in a process called transcription.
