NewsProtein-enriched ketchup gets a boost from algae extracts
Added protein is showing up in foods from breakfast cereal to pasta, but not many condiments … yet. Researchers have now developed an enriched tomato ketchup by incorporating protein extracted from microalgae.

NewsRedistributing sunlight boosts algae biomass productivity sixfold
Researchers have developed a low-energy way to distribute sunlight more evenly throughout algae cultivation systems. The technology increased algae biomass productivity by as much as six times in outdoor testing.

NewsBloomNet turns lake data into early algal bloom warnings
A research team has developed BloomNet, an interpretable deep-learning framework that forecasts harmful algal blooms at hourly resolution up to 72 hours ahead while also showing how risk changes over time.

NewsThe Great Barrier Reef has a microbiome too
A study documents over 800,000 microbial genomes, identifying over 500 new bacterial species and over 300,000 distinct viruses in the waters of the Great Barrier Reef.

NewsFrog protein could become first antidote to deadly red tide toxin
Red tide algal blooms produce one of the most potent neurotoxins known: saxitoxin, or STX. Researchers have found that a protein called saxiphilin can neutralize saxitoxin in mice, preventing and even reversing otherwise lethal poisoning.

NewsCyanobacterial toxins can be inhaled
Research on Southwest Florida cyanobacterial blooms shows that the toxins they produce are aerosolized, potentially being inhaled by people far from contaminated water bodies.

NewsBacteria form ‘herds’ to survive predators, offering fresh insight into Earth’s carbon cycle
Researchers have discovered that tiny photosynthetic bacteria band together into protective ‘herds’ when attacked by predators – a survival strategy that could also influence how carbon is stored in the world’s waters.

NewsPhytoplankton apply the onion skin principle
The phycosphere, which surrounds ocean microalgae, is one of the most important marketplaces for organic carbon in the oceans. A new study of chemical signals in this region suggests that the phycosphere consists of multiple layers.

NewsArctic microplastics: A ticking time bomb for climate feedback loops
A new study systematically maps the major transport pathways—atmospheric, oceanic, and local—and details how microplastics infiltrate Arctic food webs and interact with physical and biogeochemical processes that govern regional climate.

NewsSouth Australian algal bloom species the world’s most toxic harmful microalga yet recorded
The marine microalgae responsible for the most devastating effects of the South Australian harmful algal bloom (HAB) has now been shown to be the most toxic species of its kind ever studied.
-
NewsScientists discover how algae colonized corals, jumpstarting the growth of the world’s reefs
A research team questioned why algae are able to thrive inside the cells of coral? The finding could lead to new insights into why algae and coral are failing to thrive symbiotically and suggest ways to reestablish the connection and save the world’s reefs.

NewsWhat D.C.’s algal bloom reveals about a growing water threat
Environmental engineer Steven Chapra speaks out about cyanobacteria algal blooms in the newly renovated Lincoln Memorial Reflecting Pool, expanding on why harmful algal blooms are a growing concern, and what they may mean for freshwater ecosystems.
-
NewsCorals show climate change is reshaping the rules of survival
Which species benefit from climate change, and which are coming under pressure? Using corals as an example, researchers demonstrated that even seemingly successful life strategies can lose their advantage when environmental conditions change.

NewsStudy: China reverses widespread freshwater deoxygenation via wastewater management
Freshwater ecosystems worldwide have been suffering from declining oxygen levels that threatens biodiversity, fisheries, and ecosystem stability. However, a new study offers hope: targeted nutrient management via wastewater control can reverse this trajectory, even in the face of rapid climate warming.

NewsHow cyanobacteria developed photosynthetic membranes over the course of evolution
New research analyses hundreds of cyanobacterial genomes to understand the origin of thylakoids, the internal membranes involved in photosynthesis.

NewsAlgae microbots take aim at bladder cancer
Tiny algae-based robots guided by magnets could improve bladder cancer treatment by boosting delivery of chemotherapy drugs into tumours. Tracked using real-time imaging, the miniature robots help drugs penetrate deep into tumour tissue while limiting damage to healthy cells.
-
NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.
-
NewsBiochar-coated catalyst turns wet microalgae into cleaner fuel-building chemicals
Turning microalgae into usable liquid fuels remains difficult because algae-derived bio-oil often contains high levels of oxygen and nitrogen compounds. A new study reports a promising strategy to address this challenge.

FeaturesUnder the microscope: extremophiles of the Earth
Extremophiles are microbial organisms that live in extreme environments normally considered uninhabitable. Over the past few decades, extremophiles have been discovered in increasingly bizarre and unexpected environments around the globe, including within acid lakes, plastic recycling centres and even in radioactive sites such as Chernobyl.

NewsHow sea-ice microbes survive the Southern Ocean’s harsh winter, and the implications for climate change
New study reinforces the importance of the Southern Ocean marginal ice zone as a critical hotspot for global sulfur cycling where biogeochemical processes for climate regulation are enhanced.
