Oxygen deficiency rewires mitochondria

Mitochondria burn oxygen and provide energy for the body. Cells lacking oxygen or nutrients have to change their energy supply quickly in order to keep growing. Scientists from the Max Planck Institute for Biology of Ageing ...

The gene helping submerged plants

Climate change threatens plants as the risks of flooding increase. A new study from Stockholm University shows that special genes are key to keeping plants from withering, remaining healthy and resistant to a lack of oxygen ...

Reefs recovered faster after mass extinction than first thought

Metazoan-dominated reefs only took 1.5 million years to recover after the largest species extinction 252 million years ago, an international research team including paleontologists from the University of Zurich has established ...
