NewsUpwelling promotes N-fixing symbiont of Sargassum algae - giving it an edge
An international research team has uncovered the main mechanism behind the algae blooms of the Great Atlantic Sargassum Belt. Identification of the climatic conditions that facilitate this phenomenon allows them to predict future stranding events of Sargassum.

NewsCAROSEL offers new ‘spin’ on monitoring water quality in real time - and tracking harmful algal blooms
Researchers can continuously track the exchanges of different forms of nitrogen between bottom sediments and the overlying water. Their novel approach enables measuring how much ammonium (NH₄⁺) is released from sediments in real time, multiple times a day, over an extended period.

NewsTiles, leaves and cotton strips offer practical, affordable method for measuring river health
With the aim of standardising methods for assessing river health and providing a simple, accessible guide for environmental management bodies, researchers analysed the performance of different materials that enable the decomposition processes and organic matter production to be measured.

NewsHow algae help corals bounce back after bleaching
A $1.1 million project will uncover how reefs regain life-giving algae after suffering from heat stress. The three-year project will use advanced imaging and living experimental systems to learn what’s happening on a cellular level when algae return to bleached reefs.

NewsLichens and drones reveal dinosaur bones
Scientists have found that certain lichen species preferentially colonise exposed dinosaur bones, creating distinctive spectral signatures that can be detected from 30 metres above ground using drones.

NewsGroundbreaking new projects launched to lower the cost of monoclonal antibody production
LifeArc and the Gates Foundation have awarded more than $5m to seven projects aimed at developing cheaper and more efficient ways to produce monoclonal antibody (mAb) treatments. The innovative approaches include using filamentous fungus to produce mAbs.

NewsMarine algae use unique pigment to shield photosynthesis from excess light
Researchers have discovered that marine algae have evolved unique pigments not only to capture the green-blue light available underwater but also to enhance their resilience against excessive sunlight.

NewsImportant algal phenomenon discovered in the Arctic – could boost marine life
The shrinking sea ice in the Arctic Ocean is, overall, a disaster. But paradoxically, the melting of the ice can also fuel the engine of the Arctic food chains: algae. A new study indicates there will probably be more of it in the future than previously thought.

NewsScientists turn algae and crop waste into valuable fuels and nanomaterials
Researchers have developed a clean and efficient process to transform microalgae and agricultural residues into a range of high-value products, including biofuels, bio-adsorbents, and fluorescent carbon nanodots.

NewsDual feeding strategy helps Mediterranean coral thrive in rising sea temperatures
An exceptional “dual feeding” strategy underlies a Mediterranean coral’s resilience to rising sea temperatures, according to a study. The stony coral Oculina patagonica is known to feed itself with or without algae.

NewsAlgae and water fleas in lakes: Light color influences food webs
Phytoplankton are the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.

NewsLake Tahoe algae experiment suggests seasonal shifts ahead
As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakeswill likely experience seasonal changes, according to a new study. The effects of climate warming were especially pronounced in the colder months.

NewsScientist invents MICROCAP, an algae-based oxygen generator that removes CO₂ and purifies indoor air
A lecturer in Thailand has invented the MICROCAP air purifier, which uses photosynthetic algae to absorb carbon dioxide and produce 20 times more oxygen than trees.

NewsClimate change may increase the spread of neurotoxin in the oceans
Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study which suggests that similar processes could occur in today’s warming oceans.

NewsEarth’s oxygen boom: a fresh perspective for a billion-year-old problem
A new study examines nickel and urea in early microbial habitats, showing how ancient cyanobacteria adapted to their chemical surroundings. By recreating Archean conditions in the lab, researchers uncovered clues about the delicate balances that shaped early cyanobacterial life.

NewsTiny architects, titanic climate impact: scientists call for coccolithophores to get their own day
Five European research organisations have launched an initiative to make 10 October International Coccolithophore Day, highlighting their crucial role in regulating the planet’s carbon balance, producing oxygen, and sustaining the ocean ecosystems that underpin all life.

NewsDo stranded dolphins have Alzheimer’s disease - and how are cyanobacteria involved?
Scientists have come up with an unusual hypothesis: perhaps dolphins become disoriented by suffering from a form of Alzheimer’s disease. It appears that Alzheimer’s-type neuropathology and disorientation may result from chronic exposure to toxic molecules produced by cyanobacteria.

NewsHigh-latitude phytoplankton particularly sensitive to climate change
A team of researchers have investigated how high-latitude phytoplankton communities responded to ancient climate warming. High-latitude communities are historically understudied and likely to be particularly sensitive to human-driven climate change.

NewsMicrobial DNA sequencing reveals nutrient pollution and climate change reinforce lake eutrophication
A new study using DNA sequencing of lakebed microbes reveals that nutrient pollution from agricultural runoff and climate change amplify each other in ways that profoundly affect the health of lake ecosystems.

NewsCell death in microalgae resembles that in humans
For the first time, researchers have observed the same type of programmed cell death in microalgae as in humans. The discovery shows that this central biological process is older than previously thought.
