NewsExtreme diatoms inside the Arctic ice glide into the record books
Diatoms found in polar ice are active until temperatures drop to -15 C - the lowest ever recorded for movement by a eukaryotic cell.

NewsOcean warming puts vital marine microbe Prochlorococcus at risk
A new study finds that Prochlorococcus prefers ocean water between 66 and 86 degrees and doesn’t tolerate water much warmer. Climate models predict that subtropical and tropical ocean temperatures will exceed that threshold in the next 75 years.

NewsMicroalgae are more significant for carbon dioxide absorption in the Southern Ocean than previously thought
14,000 years ago, algal blooms in the Southern Ocean helped to massively reduce the global carbon dioxide content of the atmosphere – as has now been revealed by new analyses of ancient DNA. Declines in sea ice pose a serious threat to these algae.

NewsTiny ocean partnership between algae and bacteria reveals secrets of evolution
The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence, a new study shows.

NewsNew study finds concerning sea star response to an algal neurotoxin
Researchers found potentially concerning concentrations of the neurotoxin domoic acid in sea stars even in the absence of the algal blooms that are thought to drive DA outbreaks.

NewsUnicellular cyanobacterium UCYN-B significantly contributes to global oceanic nitrogen fixation
Researchers report that the cyanobacterium UCYN-B drives high N2 fixation rates in previously unrecognized hotspots accross the global ocean, making a significant contribution to the ocean’s nitrogen supply and productivity.

NewsNew study reveals phytoplankton’s contribution to centuries-long ocean carbon storage
Phytoplankton have long been viewed as transient players in the global carbon cycle, but researchers have discovered that these tiny organisms can directly pump “stubborn” carbon into the ocean, where it may persist for centuries.

NewsStudy reveals the microbial battlegrounds within estuaries - and the part played by microplastics
Estuaries are known hotspots for biodiversity and are turbulent mixing zones where freshwater and seawater microbes confront one another. Source: Jeff Schmaltz, MODIS Land Rapid Response Team, NASA GSFC The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image of the Baltic Sea ...

NewsResearchers create improved natural blue food dye from algae
Food scientists have created a natural blue food dye made of algae protein that could replace petroleum-based artificial food colorants with a stable, adaptable option.

NewsNew study illuminates how diatoms thrive in — and light up — the Southern Ocean
An area of the remote Southern Ocean that’s long confused ocean color satellites by reflecting large amounts of turquoise-colored light appears to be full of silica-rich diatoms, according to a new study. There is also evidence in these polar waters of coccolithophores.

NewsNew study: Powerboats can impact lakes below the surface, stimulating algaL growth
Large surface waves produced by powerboats are a mainstay for recreational watersports. A new study shows that beneath the surface, factors such as propeller thrust and other types of waves can impact delicate lakebed ecosystems.

NewsTiny artificial cells can keep time, study finds
A team of researchers has shown that tiny artificial cells can accurately keep time, mimicking the daily rhythms found in living organisms like cyanobacteria. Their findings shed light on how biological clocks stay on schedule despite the inherent molecular noise inside cells.

NewsDecoding the blue: Advanced technology realizes potential in harmful algal bloom monitoring
Researchers have developed a powerful new method to detect harmful blue-green algae in freshwater lakes. Their method can identify toxin producing blue-green algae before they become damaging in recreational waters and pose threat to public health.

NewsEngineered yeast converts methanol into valuable compound α-farnesene at scale
Farnesene, a high-value chemical intermediate, has applications in fragrance and pharmaceutical synthesis as well as aviation fuel formulations.To reduce reliance on food-based feedstocks, researchers have engineered microbial cell factories capable of utilizing methanol.

NewsHarmful algae blooms have secret to success over other algaes
An alga that threatens freshwater ecosystems and is toxic to vertebrates has a sneaky way of ensuring its success: It suppresses the growth of algal competitors by releasing chemicals that deprive them of a vital vitamin.
-
NewsNew study reveals how corals teach their offspring to beat the heat
A new study shows that rice coral, an important reef-building species, passes on thermal resistance to their offspring and avoids coral bleaching. Understanding this is important to building healthier coral reefs and protecting their future.

NewsRNA viruses may differentially shape carbon recycling in the ocean
A new study has uncovered that certain ocean viruses—specifically RNA viruses—may disrupt how carbon and nutrients are recycled in the ocean, potentially altering the global carbon cycle.
-
NewsMicroalgae-based production of dietary protein using solar-derived formate
Researchers have established a robust Chlamydomonas reinhardtii cultivation system capable of rapid growth using formate as the carbon source. They achieved successful algal cultivation at 200 mM formate concentration - the highest level ever reported in microalgae systems.

NewsIlluminated sugars show how microbes eat the ocean’s carbon
A team of scientists have designed a molecular probe that lights up when a sugar is consumed. They described how the probe helps to study the microscopic tug-of-war between algae and microbial degraders in the ocean.
