New technique boosts cryo-electron microscopy clarity, safety

When scientists needed to visualize the structure of the spike protein, which coronaviruses use to infiltrate human cells, they turned to cryo-electron microscopy. One of the most powerful imaging tools in a researcher's ...

Mind the nanogap: Fast and sensitive oxygen gas sensors

Oxygen (O2) is an essential gas not only for us and most other lifeforms, but also for many industrial processes, biomedicine, and environmental monitoring applications. Given the importance of O2 and other gases, many researchers ...

Electromagnetic anomalies that occur before an earthquake

It has been documented over hundreds of years that various electromagnetic anomalies occur a few weeks before the occurrence of a large earthquake. These electromagnetic anomalies are variations that appear in telluric current, ...

Wearable sensors that detect gas leaks

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect ...

Biobased chemicals take center stage

Usually, when oil prices fall, biobased chemical firms struggle. But these days, alternatives to petroleum-based products are undergoing a renaissance. Consumers are increasingly eco-conscious, leading companies to partner ...

A new material for light-matter interactions

Ecole Polytechnique Federale de Lausanne scientists have coupled a new material with light at the level of a single photon. The achievement opens up prospects for better controlling and understanding the properties of quantum-correlated ...
