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.

NewsCoveted lac pigment may have a fungal origin
The colourful pigment extracted from the lac insect may actually be produced by a symbiotic yeast-like organism living inside the insect, a new study has found. The yeast-like organism exclusively harbours genes coding for key ingredients in the pigment synthesis pathway.

NewsMicrobiome stability shapes how corals withstand extreme heat
A new study reveals why some corals resist bleaching while others don’t: the answer lies in a complex partnership between corals and their microbial allies, shaped by the history of the waters they inhabit.

NewsCoral Art: Drawing out the secrets of coral reef resilience to high ocean temperatures
A researcher uses her art to explain how corals from more variable ocean environments may be better equipped to survive rising ocean temperatures than corals from more stable environments.

NewsStudent discovers long-awaited mystery fungus sought by LSD’s inventor
A student has found a long sought-after fungus that produces effects similar to the semisynthetic drug LSD, which is used to treat conditions like depression, post-traumatic stress disorder and addiction.

NewsHeat-tolerant symbionts a critical key to protecting elkhorn coral from bleaching during marine heatwaves
Heat-tolerant symbiotic algae may be essential to saving elkhorn coral (Acropora palmata)—a foundational species in Caribbean reef ecosystems—from the devastating impacts of marine heatwaves and coral bleaching.

NewsDual associations with two fungi improve tree fitness
Many tree species have formed a concurrent symbiosis with two different groups of mycorrhizal fungi. Those trees cope better with water and nutrient scarcity, which is an important trait for forestry in the face of climate warming.

NewsA step towards life on Mars? Lichens survive Martian simulation in new study
For the first time, researchers have demonstrated that certain lichen species can survive Mars-like conditions, including exposure to ionising radiation, while maintaining a metabolically active state.

NewsProfessor investigates how symbiotic groups - like corals and biofilms - can behave like single organisms
UNCG philosopher of biology Dr. Derek Skillings is the lead investigator on a new, three-year, $600,000 grant from the John Templeton Foundation for a study of the emergence and evolution of goal-directed behavior in collective entities.

NewsWe feed gut microbes sugar, they make a compound we need
Gut microbes that were thought to feed exclusively on dietary fiber are also fed sugar from our guts, from which they produce short-chain fatty acids that are crucial to many body functions.

NewsHidden fungal allies strengthen defenses of black poplars and influence insect interactions
Endophytic fungi inside the leaves strengthen the chemical defenses of black poplars and influence the interactions between insect populations living on the trees.

NewsHeat-stressed reefs may benefit from coral-dwelling crabs
A species of branching coral is able to recover from heat stress and wounds due to its mutualistic relationship with crabs in the Great Barrier Reef Corals, a new study shows. This evolutionary partnership will inspire coral reef restoration strategies in the future.

NewsStudy reveals how anemonefish avoid stings from their sea anemone hosts - bacteria could be involved
Researchers have made a breakthrough in understanding how anemonefish can live safely among sea anemones without being stung by their venomous tentacles, solving a century-long mystery.

NewsScientists reveals how tiny algae shaped the evolution of giant clams
Scientists have sequenced the genome of the most widespread species of giant clam, Tridacna maxima, to reveal how these creatures adapted their genome to coexist with algae living inside them.

NewsReading the genome and understanding evolution: Symbioses and gene transfer in leaf beetles
A new study shows how repeated horizontal gene transfer and the establishment of symbioses with bacteria enabled leaf beetles to rapidly adapt to a plant-based diet, contributing to their remarkable evolutionary success.

NewsDeep-sea corals are home to previously unknown bacteria with extremely small genomes
Scientists have discovered two highly unusual bacterial species in the tissue of deep-sea corals from the Gulf of Mexico. The previously unknown coral symbionts have an extremely reduced genome and lack the ability to obtain energy from carbohydrates.

NewsWater fern offers safe potential global food insecurity solution - with no cyanotoxins
An international effort to test Azolla found that it does not contain cyanotoxins, potent toxins produced by a type of cyanobacteria, or blue-green algae, associated with the plant.

NewsStudy yields evidence of oldest confirmed photosymbiosis in corals
Researchers have demonstrated, using nitrogen isotope analyses, that some extinct corals from the Middle Devonian period were already symbiotic. This represents geochemical evidence of the oldest confirmed photosymbiosis in corals.

NewsSymbiotic bacterium affects reproduction of biological control insect
Researchers have revealed that the symbiotic bacterium Rickettsia induces strong cytoplasmic incompatibility (CI) in the predatory mirid bug, Nesidiocoris tenuis, which preys on agricultural pests such as whiteflies and thrips.

NewsResearchers create new framework to understand how microbial communities emerge
Virtually all multicellular organisms on Earth live in symbiotic associations with very large and complex microbial communities known as microbiomes. New research has just been published aimed at offering a complete understanding how those relationships form.
