NewsA Sustainable Development Goal for space?
Scientists have called for the designation of a new United Nations Sustainable Development Goal (SDG) with the aim to conserve and sustainably use Earth’s orbit, and prevent the accumulation of space junk.

NewsTiny microbe colonies communicate to coordinate their behavior
A new study reveals evidence of electrical signaling and coordinated behavior in choanoflagellates, the closest living relatives of animals. This cell communication offers insights into the early evolution of animal multicellularity and nervous systems.

NewsStudy uncovers previously unknown bacterial mode of resistance against viruses
Researchers have discovered a unique mechanism that protects marine bacteria from viruses that attack them.
-
NewsStudy uncovers complex drivers of phytoplankton bloom
A new study investigates three key processes, each triggered by different aspects of the wind field, that drive the upward transport of nutrients to the surface capable of triggering plankton blooms at the equator.

NewsStudy reveals the hidden genomic evolution of brown algae - and how bacteria and viruses helped
A groundbreaking study has unveiled the evolutionary journey of brown algae through a comprehensive genomic analysis of 44 species, including key evolutionary milestones, such as the transition from unicellular to multicellular forms.

NewsPhytochromes: The ‘eyes’ that enable microalgae to find their way in the depths
By studying the light perception process of diatoms, a group of phytoplankton, scientists have discovered that these microalgae use light variation sensors which are codified in their genomes: phytochromes.

NewsLiving in the deep, dark, slow lane: first global appraisal of microbiomes in earth’s subsurface environments
A new study reveals astonishingly high microbial diversity in some of the Earth’s deepest, darkest subsurface environments, including gold mines, in aquifers and deep boreholes in the seafloor.

NewsOcean microbe’s unusual pair of enzymes may boost carbon storage, study suggests
Scientists have discovered multiple forms of a ubiquitous enzyme in microbes that thrive in low-oxygen zones off the coasts of Central and South America.

NewsGiant virus encodes key piece of protein-making machinery of cellular life
Researchers recently discovered that a virus, FloV-SA2, encodes one of the proteins needed to make ribosomes, the central engines in all cells that translate genetic information into proteins. This is the first eukaryotic virus found to encode such a protein.

NewsDeep-sea hydrothermal vent bacteria hold key to understanding nitrous oxide reduction
Scientists have unearthed a clue to the molecular mechanisms involved in N2O reduction by deep-sea hydrothermal vent bacteria.

NewsStudy offers insight into chloroplast evolution
Researchers have found evidence suggesting that the primary role of primitive chloroplasts may have been to produce chemical energy for the cell and only later shifted so that most or all of the energy they generated was used for carbon assimilation.

NewsTiny poops in the ocean may help solve the carbon problem
Zooplankton could capture carbon dioxide originating from Earth’s atmosphere and deposit it deep into the sea as feces. The new technique mooted consists of spraying clay dust on the surface of the ocean at the site of large blooms of phytoplankton.

NewsNew study into the ecological role of deep-sea viruses
Researchers have found that marine viruses show clear distribution patterns throughout the ocean and are influenced by the depth of the ocean rather than the specific location.

FeaturesRising tides and microbes: how climate change Is reshaping aquatic life
As global warming raises sea temperatures, the effects have altered aquatic life - especially in microbial communities.

NewsDr François Thomas named as winner of Rachel Carson Prize
Dr François Thomas, an independent researcher with the Centre National de la Recherche Scientifique (CNRS, France) has been named as the newest winner of the Rachel Carson Environmental Conservation Excellence Award.

NewsOcean density identified as a key driver of carbon capture by marine plankton
Changes in ocean density have a significant impact on the rate at which marine plankton incorporate carbon into their shells, with profound implications for carbon cycling and the ocean’s ability to absorb atmospheric CO2 in response to climate change.

NewsOceans emit sulfur and cool the climate more than previously thought
Researchers have quantified for the first time the global emissions of a sulfur gas produced by plankton, revealing it cools the climate more than previously thought, especially over the Southern Ocean.
-
NewsSpecialist under-ice species at risk as Arctic warms
’Specialist’ lifeforms that live under Arctic sea ice are at risk as the ice retreats, new research shows. Scientists studied microscopic organisms in four environments – open ocean, river mouths, coasts and under sea ice – in the sea off northern Canada.
