NewsSea zombies: Viruses keep the most common marine bacteria in check
The ocean waters surrounding the German island of Helgoland provide an ideal setting to study spring algae blooms, a focus of research at the Max Planck Institute for Marine Microbiology since 2009.

NewsRegenerating worms have genetic control over their algal partners
Researchers have found that when Convolutriloba longifissura, a species of acoel that hosts the symbiotic algae Tetraselmis, regenerates, a genetic factor that takes part in the acoel regeneration also controls how the algae inside of them reacts.

NewsGenomes of ‘star algae’ shed light on origin of land plants
An international group of researchers has generated the first genome data of on four filamentous ‘star algae’ of the genus Zygnema - among the most closely related to land plants.

NewsGold may be key element for cleaner drinking water
Researchers are exploring the use of gold to develop a novel method to rid drinking water of harmful algal blooms, or HABs, which occur when colonies of algae grow out of control and produce toxic or harmful effects on living creatures.

NewsGreen-to-red transformation of Euglena gracilis using bonito stock and intense red light
Scientists investigate a simple and sustainable method to increase the growth and carotenoid content ratio of an edible microalga.

NewsThe nitroplast revealed: a nitrogen-fixing organelle in a marine alga
A nitrogen-fixing bacterial endosymbiont of marine algae is evolving into a nitrogen-fixing organelle, or nitroplast, thereby expanding a function that was thought to be exclusively carried out by prokaryotic cells to eukaryotes.

NewsAdditional nutrients intensify dead zones in oceans
As more and more nutrients from land and air enter the world’s oceans, the dead zones without oxygen in the water will increase in size and intensity, a new study warns.

NewsIn Lake Erie, climate change scrambles zooplankton’s seasonal presence
A new analysis of zooplankton in western Lake Erie shows that their biomass and seasonal behavioral patterns have been drastically altered by human-driven changes in water temperature and food webs.

NewsResearchers 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.

CareersLaboratorio Calidad de Aguas
The Water Quality Laboratory of the National University of Salta, founded by Dr Mónica Salusso and Dr. Liliana Moraña, is going from strength to strength - but faces challenges posed by major budget cuts to science and research in Argentina.

NewsMarine algae implants could boost crop yields
Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.

NewsUnusual photosynthesis configuration in dinoflagellate may reveal secrets of success
The photosynthesis process in Prorocentrum cordatum, a globally widespread species of the dinoflagellates group, is organised in an unusual configuration which may help them to better adapt to the changing light conditions in the oceans.

NewsAlgae and bacteria boost production of green hydrogen and biomass while cleaning water
The mutual relationship between an algae and three bacteria presents the highest hydrogen production obtained so far by this type of consortium.

NewsNitrogen has been underestimated in lake ecosystems, researchers warn
A new study shows that algae growth in shallow lakes around the world is affected not only by phosphorus but also by nitrogen.

NewsStudy reveals convergent evolution of algal CO2-fixing organelles
Various pyrenoid-associated proteins have been reported among the algae studied, suggesting that CO2-fixing organelles evolved independently in each algal group.

NewsVitamin B12 adaptability in Antarctic algae has implications for climate change
A new study shows that the algae Phaeocystis antarctica has the ability to survive without B12, something that computer analysis of genome sequences had incorrectly indicated.

NewsNew research finds that dust in atmosphere is feeding algae in mountain lakes
Dust deposition from the atmosphere acts as a fertilizer for algae in mountain headwaters, broadening its growth tolerance against other stressors, a new study shows.

NewsStatistics give a chance to prevent river tragedies like the Oder River crisis
Researchers believe there is a possibility of avoiding fish kills like the one in the Oder River in summer 2022, which was caused by the abrupt proliferation of golden algae, triggered by a combination of various factors. But it requires a change in the approach to analyzing parameters recorded at river monitoring stations.
