NewsResearchers uncover sensory abilities of bacteria in the gut
An international team has shown that commensal bacteria can perceive and respond to diverse chemical stimuli in their environment. They focused on Clostridia, motile bacteria that play an important role in gut health.

NewsUnicellular cyanobacterium UCYN-B significantly contributes to global oceanic nitrogen fixation
Researchers report that the cyanobacterium UCYN-B drives high N2 fixation rates in previously unrecognized hotspots accross the global ocean, making a significant contribution to the ocean’s nitrogen supply and productivity.

NewsNew study reveals phytoplankton’s contribution to centuries-long ocean carbon storage
Phytoplankton have long been viewed as transient players in the global carbon cycle, but researchers have discovered that these tiny organisms can directly pump “stubborn” carbon into the ocean, where it may persist for centuries.

NewsStudy reveals the microbial battlegrounds within estuaries - and the part played by microplastics
Estuaries are known hotspots for biodiversity and are turbulent mixing zones where freshwater and seawater microbes confront one another. Source: Jeff Schmaltz, MODIS Land Rapid Response Team, NASA GSFC The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite captured this true-color image of the Baltic Sea ...

NewsStudy finds fungus metabolites may help ghost shrimp survive
Researchers have found that chemical byproducts produced by the amphibian-killing fungus Batrachochytrium dendrobatidis—commonly known as Bd—may actually help ghost shrimp survive.

NewsCorals in Brazilian archipelago capture carbon equivalent to the burning of 324,000 liters of gasoline per year
A single species found in the Alcatrazes Archipelago, brain coral, produces around 170 tons of calcium carbonate annually. This represents the retention of approximately 20 tons of carbon in mineral form, which can last for centuries or millennia.

NewsNew research reveals ancient alliance between woody plants and microbes has potential to protect precious peatlands
New research shows that during historic periods of drying the growth of woody plants in a subtropical Chinese peatland improved the quality of organic matter and suppressed decomposing microbial activity.

NewsImperfect underground processes help filter wastewater in Florida Keys
Researchers find that microbial and other processes do not completely clear wastewater shallowly injected into groundwater of potentially harmful contaminants.

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.

NewsBacterial signaling molecule that choreographs flip between biofilm and motility could transform biotechnology and medical applications
A bacterial signaling molecule involved in flipping the switch between sessile and motile forms could offer huge potential in improving probiotics, boosting wastewater treatment and producing therapeutic compounds.

NewsResearchers discover cause of sea star wasting disease
Researchers have revealed the cause of sea star wasting disease (SSWD). The marine epidemic has killed billions of sea stars—representing more than 20 different species from Alaska to Mexico. SSWD is considered the largest marine epidemic ever documented in the wild.

NewsHelping me, inhibiting you: Analysis of interactions between intestinal microbiota
Researchers have analyzed the interactions between two bacteria that make up intestinal microbiota. While Faecalibacterium prausnitzii inhibits the growth of Fusobacterium varium, F. varium promotes the growth of F. prausnitzii.

NewsTwo new solutions for coral protection: a conductive biopaste and a natural healing patch
A research group in Italy has developed two new coral protection technologies for healing and restoring coral reefs: a biopaste and a natural patch, both successfully tested on real corals.

NewsTurning biodiversity upside down: Conservation maps miss fungal hotspots by focusing on plants
For decades, scientists and conservationists have been using aboveground plant biodiversity as a metric for conserving ecosystems. Now a new study finds that there is a major mismatch between aboveground plant diversity and Earth’s underground fungal biodiversity.

NewsHow bacteria use a protein associated with Alzheimer’s to fight off threats
Amyloids are perhaps best known as a key driver of Alzheimer’s disease. According to new research, these oft-maligned proteins also serve a critical role for bacteria in our environment, enabling them to fight off other “predatory bacteria.”

NewsNew research reveals diverse survival strategies of reef-building corals in response to ocean acidification
A research paper has revealed diverse survival strategies of reef-building corals in response to ocean acidification, providing a new perspective for understanding and protecting this fragile marine ecosystem.

NewsDelicious but damaging invasive golden oyster mushrooms are decreasing fungal community richness
The golden oyster mushroom has spread rapidly throughout the US since escaping from cultivation into the wild. Ecosystems invaded by the golden oyster support less diversity of fungal species and smaller numbers of native fungal species.

NewsForest trees and microbes choreograph their hunt for a ‘balanced diet’ under elevated CO2
Oak trees change their fine roots and ‘energise’ soil microbes by supplying them with a cocktail of small organic compounds, all to supplement the trees’ supply of essential nutrients when exposed to higher levels of carbon dioxide.

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.
