How plants prevent oxidative stress

When excess light energy is absorbed by plants during photosynthesis, harmful reactive oxygen species are produced. These reactive oxygen species break down important structures such as proteins and membranes, preventing ...

Trade winds ventilate the tropical oceans

Long-term observations indicate that the oxygen minimum zones in the tropical oceans have expanded in recent decades. The reason is still unknown. Now scientists at the GEOMAR Helmholtz Centre for Ocean Research Kiel and ...

Better oxygen extraction attracts commercial interest

Developing highly efficient ion transport membranes for the extraction of oxygen for industrial and medical use has earned a team of Curtin University scientists first prize in the university's Commercial Innovation Awards.

Octopus' blue blood allows them to rule the waves

Worldwide colonization by octopods is in their blood! They manage to survive temperature habitats ranging from as low as -1.8°C to more than 30°C due to their ability to keep supplying oxygen to their body tissues. A new ...

Photosynthesis: The last link in the chain

For almost 30 years, researchers have sought to identify a particular enzyme that is involved in regulating electron transport during photosynthesis. A team at Ludwig-Maximilians-Universität (LMU) in Munich has now found ...

Accelerating cellular assembly lines

The immune system generates antibodies to mark threats that need to be eliminated, and these protein complexes bind their targets with remarkable strength and selectivity. Scientists have learned how to generate cell lines ...

The blue blood of the emperor scorpion x-rayed

Biologists from Mainz University are the first to successfully crystallize the hemocyanin of the emperor scorpion to shed new light on the structure and active site of the giant oxygen transport protein.
