Turbulence creates ice in clouds

Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but can now be observed for the first time in nature. This research was published by a team ...

Mechanism to form influenza A virus discovered

The influenza A virus is known to form new strains every year. These strains are the result of small variations occurring at the level of the genome, which cause the virus to change and become unfamiliar to the immune system. ...

Putting the squeeze on soot

Running diesel engines and gas turbines at high pressure to boost power output and efficiency is harmful for the environment. Burning fuel at high pressure can significantly change the soot particles that are produced, William ...

Planet formation starts before star reaches maturity

A European team of astronomers has discovered that dust particles around a star already coagulate before the star is fully grown. Dust particle growth is the first step in the formation of planets. The researchers from the ...

Trees at nighttime trigger formation of charged particles

Understanding how climate has changed over the last centuries and will evolve in the future requires a detailed knowledge of all the climate system components, including an accurate evaluation of the effect of human activity ...

Organic films from atmospheric aerosol and sea water

Tiny particles in the air known as aerosols play an important role in cloud formation, which in turn has an impact on our planet's climate. However to date the effect of aerosols on cloud formation remains full of uncertainties. ...
