Manipulating superconductivity using a 'mechanic' and an 'electrician'

In strongly correlated materials such as cuprate high-temperature superconductors, superconductivity can be controlled either by changing the number of electrons or by changing the kinetic energy, or transfer energy, of electrons in the system. Although a large number of strongly correlated materials have been examined with different parameters to understand the mechanism of superconductivity, the range of parameter control is always limited. A versatile experimental method to achieve simultaneous control of the number and the transfer energy of the electrons has been long desired.

New study shows scientists who selfie garner more public trust

Many scientists today have embraced social media as tools to communicate their research and to engage broader audiences in scientific discovery and its outcomes. But the rise of the "social media scientist" has also led communicators and scholars to ask an important and often overlooked question: Do people trust the scientists who show up in their social media feeds?

New progress in developing an animal model of hepatitis C

Small differences in a liver cell protein have significant impacts on hepatitis C virus replication in mice and humans, findings that could facilitate the development of a mouse model of the infection. The report, led by researchers at Princeton University, was published today in the journal eLife.
