Silica aerogel could make Mars habitable

People have long dreamed of re-shaping the Martian climate to make it livable for humans. Carl Sagan was the first outside of the realm of science fiction to propose terraforming. In a 1971 paper, Sagan suggested that vaporizing ...

Highly anticipated nuclear experiment underway

Neutron stars were recently in the news because the gravitational wave observatory, LIGO, detected a neutron star merger. Neutron stars are very interesting objects. A teaspoon of neutron star matter is so dense it would ...

High pressure creates new neighbours for beryllium

The rare element beryllium is mainly known for being a component of emeralds, aquamarines, and other precious stones. However, in Nature Communications, an international team of scientists from the University of Bayreuth ...

New cuprate superconductor may challenge classical wisdom

Superconductivity is one of the most mysterious phenomena in nature in that materials can conduct electrical current without any resistance. Cuprates hold the record high superconducting temperature at ambient pressure so ...

A wearable vibration sensor for accurate voice recognition

A voice-recognition feature can be easily found on mobile phones these days. Oftentimes, we experience an incident where a speech recognition application is activated in the middle of a meeting or a conversation in the office. ...
