NewsFirst results published from major algal gene sequencing project
A new study reveals that different species of microscopic algae can behave in strikingly different ways because of their genetics.

NewsLoss of kelp forests reverberates down to microbial level
As one moves north, Maine’s kelp forests are being overtaken by dense mats of carpet-like turf algae. The steady decline of kelp, and transition into this new state, is altering the ecosystem all the way down to the microbial level, according to a new study.

NewsHeat-tolerant corals may be more vulnerable to disease, study finds
Corals that partner with heat-tolerant algae may be better equipped to survive warming oceans but that resilience comes with an unexpected trade-off. Such corals keep their stress response system in a heightened state - and that can backfire.

NewsScientists reconstruct past ocean temperatures from red algae
Researchers have found a new way to reconstruct daily seawater temperatures over a four-month period. The key lies in rhodoliths: nodule-like calcareous structures formed by red algae that occur in oceans worldwide.

NewsMarine heatwaves pose hidden threat to human health
Prolonged periods of unusually high ocean temperatures can trigger a cascade of effects that ultimately affect human health, from worsening extreme weather events and reducing seafood supplies to increasing mental health challenges.
-
NewsNew AI-driven technology could help combat harmful algal blooms
Researchers are developing an innovative technology that could help stop harmful algal blooms before they spread.

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.
