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.

NewsFecal samples from bowhead whales link ocean warming to rising algal toxins in Arctic waters
Rising toxins found in bowhead whales, harvested for subsistence purposes by Alaska Native communities, reveal that ocean warming is causing higher concentrations of algal toxins in Arctic food webs.

NewsScientists receive $1M grant to study gulf’s mesophotic coral habitats
Florida Atlantic University’s Harbor Branch Oceanographic Institute has received a $999,664 grant from FLRACEP for a three-year project titled, “Influences of Upwelling and Riverine Nutrient Plumes on the Mesophotic Coral Ecosystems of the West Florida Shelf.”

NewsNew insights into divergent nitrogen fixation in subtropical forests
This study focuses on two primary forms of biological nitrogen fixation (BNF): symbiotic nitrogen fixation (SNF), which occurs within the root nodules of nitrogen-fixing plants, and asymbiotic nitrogen fixation (ANF), carried out by free-living microorganisms in soil and litter.

NewsDrones reveal extreme coral mortality after bleaching
New research has revealed alarming coral mortality rates of 92 per cent after last year’s bleaching event at Lizard Island on Queensland’s Great Barrier Reef, marking one of the highest coral mortality rates ever documented globally.

NewsMultiresistant intestinal bacteria: Displacement through food competition
Researchers made use of food competition to figure out how potentially dangerous multi-resistant bacteria could be effectively removed from the gut before reaching the bloodstream and causing serious problems.
-
NewsNew study highlights neglected dynamics of coral and algae energy use
A new study has challenged a long-standing oversight in coral reef science, revealing that respiration in corals and algae varies significantly throughout the day, rather than remaining constant. It reveals that respiration rates in reef organisms are highly dynamic, peaking in the afternoon several hours after the height of photosynthesis.

News New collaboration harnesses COVID methods to combat multi-billion threat to UK forests
Harnessing methods used to successfully predict and understand the spread of COVID-19 during the pandemic, a new project aims to combat the impact of forest diseases that can cost the UK economy billions.

NewsRain showers can dramatically impact fungal communities in urban lakes
Rainfall can have dramatic effects on the microbial communities living in urban lakes, a new paper published in the Journal of Applied Microbiology reveals.

NewsNorthward jet stream shift hits phytoplankton in the Mediterranean Sea
In just over 20 years, the northward shift of the subtropical jet stream — a high-altitude airflow — caused by climate change has reduced primary production in the northwestern Mediterranean by about 40%, affecting the base of the marine food web.

NewsResearchers pinpoint fungal hotspots of ‘dark taxa’ across Earth’s underground ecosystems
A new study finds that 83% of ectomycorrhizal fungi are known only by their DNA sequences that can’t be linked to named or described species, posing problems for conservation.

NewsEndangered mountain caribou possess unique gut microbiome that may be important for recovery efforts
Endangered mountain caribou in British Columbia possess a unique gut microbiome in late winter when they feed on tree lichens, a finding that could guide caribou recovery efforts, according to a new study.

NewsFish ‘beauty salons’ offer insight into how microbes move within reefs
A new study highlights the potential impact of cleaner fish in coral reefs and the need to demystify their role in shaping reef microbial diversity and transmission.

NewsBacteria hitch a ride on yeast puddles to zoom around
Researchers found that bacteria can speed up by using the fluid pockets shaped by neighboring yeast cells. These microscopic moisture trails allow bacteria to swim farther and spread faster—revealing a new way for microbes to travel through soil, plants, and the human body.

NewsStudy resolves diatom tree of life - and could offer clues to Earth’s puzzle
A new study finds that diatoms evolved slowly for the first 100 million years of their existence. Then, 170 million years ago, they reached an inflection point characterized by a burst of rapid speciation orders of magnitude faster than anything that had preceded it.

NewsResearchers discover unusual new marine flagellate
A newly discovered species of unicellular organism found in seawater belongs to the protist group Endomyxa and is notable for possessing a persistent flagellum — the first recorded instance of such a flagellate within this group.
