Do animals control earth's oxygen level?

No more than 540 million years ago there was a huge boom in the diversity of animals on Earth. The first larger animals evolved in what is today known as the Cambrian explosion. In the time that followed, the animals evolved ...

Using lasers to study explosions

An explosion is a complex event involving quickly changing temperatures, pressures and chemical concentrations. In a paper in the Journal of Applied Physics a special type of infrared laser, known as a swept-wavelength external ...

Analysis of wildfire smoke will help calibrate climate models

Thunderstorms generated by a group of giant wildfires in 2017 injected a small volcano's worth of aerosol into the stratosphere, creating a smoke plume that lasted for almost nine months. CIRES and NOAA researchers studying ...

A prehistory of blindness

Fossils that had gone unstudied since the early 20thcentury helped a team led by University of New England (UNE) palaeontologist Dr Russell Bicknell to address a long-standing puzzle: were ancestors of the iconic horseshoe ...
