At high concentrations, reactive oxygen types — known as oxidants — are harmful to cells in all organisms and have been linked to ageing. But a study from Chalmers University of Technology has now shown that low levels of the oxidant hydrogen peroxide can stimulate an enzyme that helps slow down the ageing of yeast cells.

Researchers have analysed immune cell types and numbers from the blood of healthy volunteers, Covid-19 patients experiencing mild-to-moderate effects and patients classified as severe. After comparing the T cell immune response, the researchers noted the surprising absence of a strong anti-viral response in the blood of Covid-19 patients.

A new study by SaveOnEnergy has stated that the citizens of The Netherlands are the most interested in saving the planet followed by The UK, Austria, Sweden and Germany. The study analysed environment-conscious related search volumes within Europe to reach this conclusion.

Factors such as increasing worldwide population growth and increased levels of global warming mean that the world's freshwater resources are increasingly strained and drained. Researchers at Kaust, Saudi Arabia, are trying to harness the potential of wastewater in order to address global water scarcity.

A removable coating that can be used to clean desalination membranes has been developed by Kaust researchers. The nontoxic coating could provide a safer and more efficient alternative to harmful chemicals used to clean reverse osmosis systems for seawater desalination.

Achema 2021 has been postponed to April 4-8, 2022 due to the coronavirus pandemic. However, the organisers of the show will be hosting Achema Pulse this year from June 15-16. The new interactive platform will showcase the latest industry trends via informative discussions and also enable industry players to connect with like-minded people.

A new study spearheaded by the Nottingham Trent University has helped clinicians to identify patients with aggressive leukaemia who will fail to respond to chemotherapy. The study will also assist in identifying patients that are most likely to benefit from a new immunotherapy.

Some, if not all, early sharks that lived 300 to 400 million years ago not only dropped their lower jaws downward but rotated them outwards when opening their mouths, paleontologists at the Universities of Zurich and Chicago have now shown using CT scanning and 3D printing.

Food is both a basic need and a valuable asset. In Germany, food manufacturers must meet high requirements in terms of safety and product quality. Read about the important contribution microscopic techniques make in quality control and R&D.

Scientists at Osaka University have developed a label-free method for identifying respiratory viruses based on changes in electrical current when they pass through silicon nanopores, which may lead to new rapid Covid-19 tests.
