Like many land plants, seagrasses live in symbiosis with nitrogen-fixing bacteria. Researchers of the Max Planck Institute for Marine Microbiology in Bremen and Eawag now show that seagrass in the Mediterranean Sea lives in symbiosis with bacteria that reside in their roots and provide the nitrogen necessary for growth. Such symbioses were previously only known from land plants. The study was published in the journal Nature.

These days, the cause of death in cancer patients often isn’t the primary tumour, but metastases. With his research, biochemist Nicola Aceto has found a new way to prevent the formation of such secondary tumours. To achieve this, the Latsis laureate had to repeatedly fight against the prevailing wisdom.

Human cells are like tiny, multi-purpose factories. In his research, ETH biologist Gabriele Alessandro Fontana investigates how cells repair damaged DNA. The mechanisms he has identified will help us to gain a better understanding of diseases and to develop new drugs.

EPFL scientists have developed new controlled proteins and used to switch cellular activities on and off like a light bulb.

Europe has relatively low biodiversity compared to most other continents because many species became extinct during the ice ages. In subterranean ecosystems, however, which were shielded from climatic turbulences, a great diversity of ancient species were able to survive. This is the conclusion of a study on the amphipod genus Niphargus.

Nako Nakatsuka earned a place on this year’s MIT Technology Review’s Innovators Under 35 list for her invention of a precise chemical biosensor that empowers researchers to better understand brain processes and diseases such as Alzheimer’s, Major Depression, and Parkinson’s.
