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.

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.
-
NewsElectrochemiluminescence boosts flexible displays in wearable devices
A new review details the design, preparation, and applications of electrochemiluminescence devices, offering the potential for the development of lightweight and intelligent wearable devices.

NewsFecal samples from bowhead whales link ocean warming to rising algal toxins in Arctic waters
Rising toxins found in bowhead whales, harvested for subsistence purposes by Alaska Native communities, reveal that ocean warming is causing higher concentrations of algal toxins in Arctic food webs.

NewsScientists receive $1M grant to study gulf’s mesophotic coral habitats
Florida Atlantic University’s Harbor Branch Oceanographic Institute has received a $999,664 grant from FLRACEP for a three-year project titled, “Influences of Upwelling and Riverine Nutrient Plumes on the Mesophotic Coral Ecosystems of the West Florida Shelf.”

NewsAlgae of polar origin may impact tropical ocean biogeochemistry and food webs
A single-celled algae genus may have a big impact on how the world’s chemical building blocks cycle between living things and the non-living environment. Polarella was thought to be restricted to polar cap regions, but turns out to be abundant in the tropical Pacific ocean.

NewsFrozen, but not sealed: algal traces reveal that Arctic Ocean remained open to life during ice ages
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now a new study challenges this idea as the research team found no evidence for the presence of a massive ~1km ice shelf. Instead, the Arctic Ocean appears to have been covered by seasonal sea ice.
-
NewsNew study highlights neglected dynamics of coral and algae energy use
A new study has challenged a long-standing oversight in coral reef science, revealing that respiration in corals and algae varies significantly throughout the day, rather than remaining constant. It reveals that respiration rates in reef organisms are highly dynamic, peaking in the afternoon several hours after the height of photosynthesis.

NewsScientists uncover shortcut to miniaturized hydrogen production
Researchers have figured out a way to simplify the highly complex hydrogenase biocatalyst to facilitate its integration into industrial processes, offering a route to clean energy.
-
NewsLiving near harmful algal blooms reduces life expectancy with ALS
Living close to cyanobacterial harmful algal blooms — which are present US-wide but are more common in coastal and Great Lake states — heightens the rate of dying from amyotrophic lateral sclerosis, or ALS, a study suggests.

NewsMicrobiome stability shapes how corals withstand extreme heat
A new study reveals why some corals resist bleaching while others don’t: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.
