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.

Frozen, but not sealed: algal traces reveal that Arctic Ocean remained open to life during ice ages
For years, scientists have debated whether a giant thick ice shelf once covered the entire Arctic Ocean during the coldest ice ages. Now a new study challenges this idea as the research team found no evidence for the presence of a massive ~1km ice shelf. Instead, the Arctic Ocean appears to have been covered by seasonal sea ice.

Mushrooms could be the key to developing better materials
Researchers are studying the cell structure of fungi to learn how it determines their mechanical properties and what science can learn from that to create better materials. They analyzed their cell structures and tested them to calculate the stress loads they could handle.
NewsEnzymes from fungi can help extract plant components for biofuels and bioplastics
Plant cell wall components such as cellulose are abundant sources of carbohydrates that are widely used in biofuels and bioproducts. Investigators have found that a combination of fungal enzymes can efficiently degrade plant biomass to allow for extraction.
NewsIlluminated changes: Enhancing D-lactic acid output with UV irradiation
Researchers have developed a Komagataella phaffii (K. phaffii) yeast strain that can efficiently produce D-lactic acid, a raw material for pharmaceuticals and bioplastics, from methanol.
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.
