Volcanoes cause climate gas concentrations to vary

Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the processes in the ...

Study shows that people organize daily travel efficiently

(Phys.org) —Studies of human mobility usually focus on either the small scale—determining the origins, destinations and travel modes of individuals' daily commutes—or the very large scale, such as using air-travel patterns ...

Most distant blazar is a high-energy astrophysics puzzle

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source of very high-energy ...

Researchers tackle next-generation climate models

Tornadoes, twisting winds that descend from thunderheads, and derechos, winds that race ahead of a straight line of storms, are just two varieties of extreme weather events whose frequency and violence are on the increase. ...

Math model reveals insight into how first life forms were 'born'

An international team of physicists have revealed insights into how the very first life-forms made the jump from the non-living to the living world, by mathematically modelling biological states using energy waves called ...
