A borrowed bacterial gene allowed some marine diatoms to live on a seaweed diet
A group of diatom species belonging to the Nitzschia genus gave up on photosynthesis and now get their carbon straight from their environment, thanks to a bacterial gene picked up by an ancestor, a new study shows.

Phytochromes: The ‘eyes’ that enable microalgae to find their way in the depths
By studying the light perception process of diatoms, a group of phytoplankton, scientists have discovered that these microalgae use light variation sensors which are codified in their genomes: phytochromes.

Researcher to study role of tiny diatoms in protecting endangered marine animals
A new study is aimed at understanding the essential role played by diatoms, tiny microalgae that can live in oceans or in symbiosis with endangered marine animal hosts and play a fundamental role in maintaining Earth’s delicate ecosystem.

Study reveals environmental impact of artificial sweeteners on water microbes
A new study demonstrates how sucralose affects the behavior of cyanobacteria — an aquatic photosynthetic bacteria — and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.

Scientists unravel drivers of the global zinc cycle in our oceans
The important role of the Southern Ocean in global biological processes and the carbon cycle has been confirmed by a study that, for the first time based on field evidence, reveals the underappreciated role of inorganic zinc particles in these cycles.

New Rhizobia-diatom symbiosis discovery solves long-standing marine mystery
Scientists solve a longstanding marine mystery by uncovering a partnership between a diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean, with exciting implications also for agriculture.

Researchers investigate how freshwater diatoms stay in the light
Scientists sampled the ice-covered (in 2019) and ice-free (in 2020) winter waters of Lake Erie to learn how diatoms are responding to changing environmental conditions.

Researchers explore role of salps as predators of marine microbes
Salps play a major role in controlling the abundances and function of microbial communities in the vast nutrient-poor open ocean, with global implications, a new study reveals.

Scientists uncover new pathway of diatom-mediated calcification
Researchers have found that the photosynthesis of a common diatom can induce substantial aragonite precipitation from artificial/natural seawater under significantly lower supersaturation levels required for the precipitation of inorganic CaCO3.
