The rise of oxygen levels early in Earth's history paved the way for the spectacular diversity of animal life. But for decades, scientists have struggled to explain the factors that controlled this gradual and stepwise process, which unfolded over nearly 2 billion years.

Rocket engines contain confined combustion systems, which are, essentially, combustion chambers. In these chambers, nonlinear interactions among turbulent fuel and oxidizer flows, sound waves, and heat produced from chemical reactions, cause an unstable phenomenon called 'combustion oscillations.'

Under normal conditions, pure water is an almost perfect insulator. Water only develops metallic properties under extreme pressure, such as exists deep inside of large planets. Now, an international collaboration has used a completely different approach to produce metallic water and documented the phase transition at BESSY II. The study is published now in Nature.

New research led by the University of Bristol demonstrates that a decline in the concentration of atmospheric CO2 played a major role in driving Earth's climate from a warm greenhouse into a cold icehouse world around 34 million years ago. This transition could be partly reversed in the next centuries due to the anthropogenic rise in CO2.

Car-manufacturing powerhouse Germany is rushing to join the private sector space race as it looks to ride a boom in mini-launchers for small satellites and compete with major US firms such as SpaceX.
Three projects in particular are making Germany a serious player in the race to provide mini-launchers for the increasing number of small satellites which observe the Earth and provide connectivity for the internet of things and smart vehicles.
At the end of July, German company Rocket Factory Augsburg (RFA) carried out a first successful test of its "RFA One" rocket, igniting the engine for eight seconds at its development site in Kiruna, Sweden.
The rocket's "staged combustion" system is used by Elon Musk's SpaceX and Jeff Bezos's Blue Origin, but is yet to be rolled out in Europe.
