Ocean Sustainability
Over 70% of the earth is covered in water, which serves as a vital resource human subsistence. Contamination and acidification pose major threats to aquatic health and biodiversity. Microbes offer a promising solution in their ability to breakdown contamination from oil spills and plastics. Applied microbiologists can play a significant part in understanding biodiversity, contributing to solutions, and encouraging stewardship.
Light without electricity? Glowing algae could make it possible
Researchers successfully turned on the “light switch” in algae and kept them lit up using simple chemical solutions. The finding opens the door for future technologies such as autonomous robots that can operate in dark environments and living sensors for water quality.

Researchers unveil new AI-driven system set to transform coral reef restoration
Researchers have developed a first-of-its-kind bespoke AI system designed to assess coral health and detect early stress. BlueBiome is reimagining coral reef care by applying the same principles of preventive, precision health commonly used in human gut health.
‘Not just hot water’: marine heatwaves can create toxic relationship between seagrasses and microbes
Heat stress from marine heatwaves can create a toxic relationship between seagrasses and a hidden ecosystem of bacteria, transforming a previously beneficial co-existence between marine plants and microbes into a harmful one, a study has found.
Nutrient imbalance may drive coral disease more than heat stress, new study suggests
New research shows that an imbalance of nutrients in seawater can cause coral disease – possibly to a greater extent than that from heat stress of warming oceans. Disruption of the delicate nutrient balance of the sea can destabilise microbial communities that live in harmony with corals.

New study could help scientists produce more accurate records of past ocean change
Tiny plankton shells used to reconstruct past polar ocean temperatures may contain two different chemical stories, a new study has found.
Crab shell by-products could help regulate the marine lifetime of biodegradable plastics
Researchers show that crab shell by-products can reduce the breakdown rate of biodegradable plastics in seawater by altering the microbial communities that colonize their surfaces, known as the plastisphere.
Lost millennium of Galápagos deep-sea corals linked to major Pacific climate shift
Scientists have discovered that deep-water corals in the Galápagos region vanished for more than 1,000 years before eventually recovering. The findings reveal that deep-water coral ecosystems may be more susceptible to climate change than previously thought.
Researchers come up with novel strategies for coral restoration
Scientists have discovered a new way to help lab-grown baby corals survive through the early life stage. If young mountainous star corals are grown on cement tiles formulated with sodium carbonate, which raises the alkalinity of the water, they survive much better than the average lab-grown corals.
Andes volcanoes – the missing link between algae blooms, whales and climate millions of years ago
Record volcanic eruptions in the Andes could explain the mysterious death of dozens of whales about 5 to 8 million years ago, according to a study. A significant increase in volcanic activity in the Andes peaking between eight and four million years ago likely delivered a significant pulse of nutrients to the Southern Ocean.
Cyanobacteria surprise scientists with evolutionary shift
Researchers report a surprising new discovery—a system thought to separate DNA has developed to sculpt the shape of the cell in cyanobacteria instead. The results shed light on how protein systems evolve and how multicellularity emerged in this type of ecologically essential bacteria.
Researchers uncover a ‘treasure trove’ of bioactive molecules in coral reefs
Researchers have found that coral reefs are home to a vast array of previously unknown bioactive metabolites — small biomolecules that have the biotechnological potential to provide the basis for new drugs, and a host of other products.
Turning microalgae into high-value fuels: biochar-based catalyst unlocks cleaner aromatic production
Scientists have designed a composite catalyst that significantly improves the quality of bio-oil derived from microalgae. By combining biochar with a well-known zeolite catalyst called HZSM-5, the team created a hybrid material that enhances the production of valuable aromatic hydrocarbons while minimizing unwanted byproducts.
Seasonal cycles - even in the depths - sustain ocean microbial biodiversity
Oceanographers discovered that microbial communities–from the sunlit surface to extreme depths–in the North Pacific Subtropical Gyre exhibit robust seasonal cycles. The study provides new insight into how high levels of biodiversity are maintained in the open ocean.
Helping corals survive future heatwaves requires strong and strategic trait selection
A new study exploring host assisted evolution in corals have created a unique, pedigree-tracked coral population over the last eight years, allowing them to map family relationships and measure how multiple key traits—such as growth, reproduction and survival—are inherited.
The giants of the reef: New citizen science project races to document centennial corals
Coral reefs hide “scientific treasures” that have survived for centuries, yet many of these giant, ancient organisms remain largely unknown to science. A new study introduces a pioneering citizen-science initiative to find these giant coral colonies before they are lost to escalating global pressures.
MBL scientist Alexandra Z. Worden honored with a Guggenheim Fellowship
Alexandra Z. Worden, Senior Scientist in the Bay Paul Center at the Marine Biological Laboratory and a Professor in the Department of the Geophysical Sciences at the University of Chicago was awarded a Guggenheim Fellowship this week, in recognition of her groundbreaking research in ocean biogeochemistry.
Functional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.
Study reveals hidden damage in stony corals using 3D imaging and AI
Researchers investigating how disease affects coral structure turned to X-ray microcomputed tomography which generates detailed 3D reconstructions down to microscopic pores, which reveal internal skeletal features, including porosity, thickness and structural orientation, in a non-destructive way.
