NewsMBL 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.

NewsStudy 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.

NewsLonger-term plankton species diversity is independent of ocean mixing
A new study identifies correlations between turbulence, plankton diversity and aggregate abundance in marine coastal regions over longer time periods, providing new insights into marine ecosystems.

NewsTiny plankton have big impact on harmful algal bloom predictions
While some computer models can forecast potential algal blooms, their accuracy is limited.. A new study shows that coupling three models and accounting for how different algae species interact can significantly improve predictions.

NewsHow microbes survive in the plastisphere
Trillions of persistent plastic particles of varying sizes are scattered throughout the world’s oceans, where they often accumulate in ocean gyres known as ‘garbage patches’. Two of these regions were the focus of research expeditions.

NewsWhen algae stop growing, bacteria start swarming
A new study describes how a recently identified species of marine bacteria targets diatoms based on growth phase and nutrient availability.

NewsProlonged exposure to microplastics disrupts the metabolism of Mediterranean octocorals
Prolonged exposure to microplastics can disrupt vital physiological processes in gorgonians, such as respiration. Although these pollutants do not cause visible damage to tissues and cells, their effects could have an ecological impact on these organisms that structure the seabed.

NewsScientists reveal valuable secrets of Pacific coral reefs
An international consortium of scientists has uncovered new insights into coral ecosystems, revealing that different coral species host their own distinct communities of microbes. They show that coral reefs harbour diverse microbes and produce chemicals with promising potential.

NewsStill standing but mostly dead: Recovery of dying coral reef in Moorea stalls
In 2019, a marine heat wave struck a coral reef on the island of Moorea in French Polynesia, killing much of the coral and the beneficial algae that colonized it. A long-term study of the area is challenging scientists’ understanding of the cycles of destruction and repair that can occur on a coral reef.

NewsResearchers uncover hidden genetic world in Antarctic Waters
Researchers have completed the most comprehensive survey to date of DNA associated with Southern Ocean microbes, paving the way for a better understanding of their role in climate change. At least a third of the genes identified are missing from existing marine gene catalogs.
-
NewsNew study finds deep ocean microbes already prepared to tackle climate change
A new study demonstrates that the microbe Nitrosopumilus maritimus may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these adaptable iron-dependent ammonia-oxidizing archaea will play an important role in reshaping ocean-nutrient distribution in a changing climate.

NewsHitchhiking bacteria can alter marine snow's role as a carbon sink
Researchers have found that when bacteria hitch a ride on marine snow particles, the microbes can eat away at calcium carbonate, which is an essential ballast that helps particles sink.

NewsToxic algal bloom takes heavy toll on mental health
The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.

NewsThe new ‘forever’ contaminant? Study raises alarm on marine fiberglass pollution
Researchers investigating fibreglass contamination of an estuary looked at the biofilm and the deeper sediment layer where sediment‑dwelling invertebrates live and feed. They found fibreglass particles at several of the surface biofilm testing sites and 96 per cent of the sediment testing sites.

NewsMicroscopic plankton reveal tropicalization of the Mediterranean Sea
A recent study of the western Mediterranean demonstrates that the expansion of microscopic warm-water species provides a clear and early indication of tropicalization impacts on marine ecosystems.

NewsCorals in extreme coastal bays show greater resilience to climate stress
Corals living in coastal bays with strongly fluctuating temperatures and environmental conditions are better able to withstand heat and other stressors than their counterparts on more stable reefs.

NewsOysters play unexpected role in protecting blue crabs from disease
Oysters famously filter their surrounding water, but it turns out they are removing more than algae and excess nutrients. New research shows they can also reduce the spread of disease in nearby marine species, including Chesapeake Bay’s prized blue crabs.

NewsSediment core yields evidence of an unexpected climate feedback in Antarctica
Researchers have concluded that global warming may lead to reduced uptake of carbon dioxide than at present in the Pacific sector of the Southern Ocean if the West Antarctic Ice Sheet, which is considered unstable, continues to shrink.

NewsCorals sleep like us, but their symbiosis does not rest
A study has revealed that corals also sleep, despite not having a nervous system, while their microbiome remains awake. For the first time, a biological day-night pattern that transcends the individual and helps sustain a symbiotic relationship has been identified in situ.

NewsScientists solve 66 million-year-old mystery of how Earth’s greenhouse age ended
Experts studying foraminifera fossils have discovered that concentrations of calcium in the sea dropped by more than half across the last 66 million years, which likely caused Earth’s massive drop in temperature.
