Climate action
Today we are seeing climate change in action, increased concentrations of atmospheric greenhouse gases have led to a rise in sea levels, temperatures, and extreme weather patterns. Researchers have acknowledged the pivotal role microorganisms in producing sustainable biofuels, increasing carbon sequestration via soil microbes and reducing methane emissions in landfill sites. Microbial innovation will be vital in moving towards a low carbon economy.

NewsLiving fungus-based building material repairs itself for over a month
Engineers have developed a building material that uses the root-like mycelium of a fungus and bacteria cells. They show that it is capable of self-repairing and could eventually offer a sustainable alternative for high-emission building materials like concrete.
NewsOropouche virus infections underestimated in Latin America and likely to increase due to climate factors
Environmental factors, such changing temperatures and rainfall, are the main drivers associated with the spread of Oropouche virus (OROV) in Latin America, according to a modelling study.
NewsDeadly rodent-borne hantavirus is an emerging disease with pandemic potential
Researchers have found three hotspots of hantavirus circulation in wildlife in the US – Virginia, Colorado, and Texas – and identified 15 rodent species as carriers, including six species that had not previously been identified as hosts of the virus.

Dogs could help predict valley fever spread in humans
Valley fever, or coccidioidomycosis, is caused by a fungus that thrives in moist soils and becomes airborne during drought. In a new study, researchers show that dogs, who are also susceptible to the disease, can help us understand its spread.
NewsCoral reefs exude myriad chemicals, fueling dynamic microbial recycling of nutrients
New research reveals the remarkable chemical diversity of substances exuded by coral reefs and demonstrates that thousands of different chemicals derived from tropical corals and seaweeds are available for microbes to decompose and utilize.
NewsIn Croatia’s freshwater lakes, selfish bacteria hoard nutrients, shaping food webs
Researchers have documented ’selfish polysaccharide uptake’ by bacteria in freshwater ecosystems for the first time. They found that nutrient hoarding allows selfish species to dominate over others, which could shape a lake’s food web.

Climate change is creating new pathways for the spread of infectious diseases like brucellosis, tularemia, or E. coli in the Arctic, according to a broad international consortium of scientists.
NewsThe new season of The Last of Us has a spore-ting chance at realism
The trailer for the hit HBO series appears to show the ’zombie fungus’ cordyceps infecting humans by releasing air-borne spores, instead of through tentacles — closer to scientific reality, according to experts.
NewsMolecular clock analysis shows bacteria used oxygen long before widespread photosynthesis
Researchers have constructed a detailed timeline for bacterial evolution and oxygen adaptation. Their findings suggest some bacteria could use trace oxygen long before evolving the ability to produce it through photosynthesis.
NewsScientists create ‘fungi tiles’ with elephant skin texture to cool buildings
Scientists have developed ‘fungi tiles’ that could one day help to bring the heat down in buildings without consuming energy. These tiles have bumpy, wrinkly texture to the tile, mimicking an elephant’s ability to regulate heat from its skin.
