Argon found in air of ancient atmosphere

On the massive sheets of ice that stretch across Greenland and Antarctica, the temperature is so low that not even the summer sun can melt the snow deposited onto them. As the snow accumulates without melting and settles ...

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 ...
