Treating arthritis with algae

Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis. This is based on a polysaccharide, a long-chain sugar molecule, originating from brown algae. When chemically modified, this “alginate” reduces oxidative stress, has an anti-inflammatory effect…

Diatoms indicating the future

Peter Rüegg writes for Phys.org that, during their rapid growth cycle, diatoms absorb huge amounts of trace elements and nutrients from the surface water layer, especially silicon to form their shells, and zinc, which plays a vital physiological role in their development. The heavy depletion of nutrients caused by the…
