NewsNew method uncovers dynamic microbial community in coastal sediments
Scientists utilises single celll genomics and cell staining approaches to investigate the respiratory rates and metabolic activities of the diverse microbial communities in low biomass aqautic environments, such as Maine’s coastal sediments.

NewsA study identifies ‘surprising’ cause of sargassum blooms in the Caribbean
A group of interantional researchers identified the cause of sargassum blooms in the tropical Atlantic Ocean using computer modelling. They have modelled the ocean currents, wind pattern and the growth conditions that help them thrive in the region.

NewsSulfur-reducing bacteria team-up to break down organic substances in the seabed
Researchers have decoded the molecular strategies employed by the underappreciated sulfate-reducing bacteria, <i>Desulfobacteraceae</i>, which is capable of breaking down organic carbon in the oxygen-limited seabed.
-
NewsHeat-stressed reefs may benefit from coral-dwelling crabs
A species of branching coral is able to recover from heat stress and wounds due to its mutualistic relationship with crabs in the Great Barrier Reef Corals, a new study shows. This evolutionary partnership will inspire coral reef restoration strategies in the future.

NewsSymbiotic bacteria ride along with marine cells in ocean’s upper layer
Symbiotic bacteria often accompany single-celled protists in the ocean’s upper layer. Some of these symbionts, scientists have discovered, are close relatives of bacteria pathogenic to animals, including humans.
-
NewsResearchers glean photosynthetic insights from volcanic hot springs
With the use of mathematic modelling, scientists uncovered the mechanisms of specific algae, such as Cyanidioschyzon merolae, to survive in the extreme environment of acidic hot springs near volcanos.
-
NewsCultivation of microalga for food production shows that two-stage process yields best results
A new study looking into cultivating the microalga Nannochloropsis oceanica for food production shows that temperature and light are key factors in the yield of key nutrients.

NewsLooking to Kenya’s Lake Victoria for what may come for Lake Erie
Scientists conducted a genetic survey on cyanobacteria in the Winam Gulf of Kenya’s Lake Victoria, which serves as a model for the cyanobacterial harmful algal blooms (cyanHABs) in Lake Erie under the warming climate.

NewsLong-standing marine mystery solved: How algae get nitrogen to grow
In a new study, scientists have shed light on an unexpected partnership: a marine diatom and a bacterium that can account for a large share of nitrogen fixation in vast regions of the ocean.
-
News2,000-year-old shipworm mystery solved - its destructive skills are down to bacterial symbionts
Scientists have discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the shipworm gut called the ’typhlosole’, have the ability to secrete the enzymes needed to digest lignin—the toughest part of wood.
-
NewsRegenerating worms have genetic control over their algal partners
Researchers have found that when Convolutriloba longifissura, a species of acoel that hosts the symbiotic algae Tetraselmis, regenerates, a genetic factor that takes part in the acoel regeneration also controls how the algae inside of them reacts.

NewsPost-Idalia floodwaters may harbour flesh-eating bacteria
Following the devastation of Hurricane Idalia, health authorities are urgently cautioning beachgoers to remain vigilant as floodwaters may harbour Vibrio vulnificus, a rare and deadly flesh-eating bacterium.
-
NewsNew species of marine bacteria isolated from a deep-sea cold seep
Scientists have isolated a new species of marine bacteria that multiplies by a unique budding mechanism and releases viruses to facilitate nitrogen metabolism.
-
OpinionCould deep sea mining destroy the treasure trove of biomedical compounds yet to be found?
The idea of DSM has been proposed, backed by countries such as the UK, France, Germany, Spain, USA and China in the search for metals such as iron, manganese, copper, zinc, lead, nickel and rare metals.

CareersCreating the right climate for a marine biotechnologist
Over the past decade, Mike Allen has been trying to help solve the three challenges he sees as the major threats to humanity and our way of life: energy, water and food security.
-
FeaturesLessons learned from microbes that stick to plastic
Lower density plastics tend to float or remain in the upper 30 meters of aquatic environments, interacting with biota in ways still being deciphered.
-
NewsScientists discover a new way of sharing genetic information in a common ocean microbe
<i>Prochlorococcus</i>, the world’s most abundant photosynthetic organism, reveals a gene-transfer mechanism that may be key to its abundance and diversity.
-
NewsThree compounds from sea sponge and marine bacteria offer Covid-blocking powers
University of British Columbia researchers have identified three compounds that prevent COVID-19 infection in human cells, derived from natural sources including a BC sea sponge.
-
NewsPlankton may reveal ocean history - and even predict trends in chronic human illness
Tapping an almost century-long survey, University of California San Diego School of Medicine researchers say marine plankton may offer way to monitor historical marine pollution trends; and perhaps be used to predict trends in childhood and adult chronic illnesses.
-
NewsNew technique reveals marine microbes’ outsized role in carbon cycle
A small fraction of marine microorganisms are responsible for most of the consumption of oxygen and release of carbon dioxide in the ocean, new research suggests.
