Plants feel the heat

It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...

Shocking results of galaxy-cluster collisions

A giant collision of several galaxy clusters, each containing hundreds of galaxies, has produced this spectacular panorama of shocks and energy. The collisions generated shock waves that set off a celestial fireworks display ...

Researchers discover new pathway for handling stress

Balance is key to many physiological functions and it is especially true in the production and regulation of proteins. A balance of proteins in cells helps maintain health, but an unhealthy clumping can lead to a variety ...

3-D supernova simulations reveal mysteries of dying stars

An international team of researchers led by a Monash astronomer has created the longest consistent 3-D model of a neutrino-driven supernova explosion to date, helping scientists to better understand the violent deaths of ...

The moving Martian bow shock

As the energetic particles of the solar wind speed across interplanetary space, their motion is modified by objects in their path. A study, based on data from ESA's Mars Express orbiter, has thrown new light on a surprising ...

Astrophysicists explain the mysterious behavior of cosmic rays

A team of scientists from Russia and China has developed a model explaining the nature of high-energy cosmic rays (CRs) in our galaxy. These CRs have energies exceeding those produced by supernova explosions by one or two ...
