Healthy land
Land has a wide variety of uses: agricultural, residential, industrial, and recreational. Microbes play a key role in the terrestrial ecosystem, providing symbiotic relationships with plants. Human use of land has led to the exhaustion of nutrients in soils, contamination of land, and a reduction in biodiversity. Applying our knowledge of microbes will be essential in restoring the biodiversity of affected ecosystems. Greater research into how microbes impact human life on land could all have a positive impact, by increasing crop production, repurposing areas of land and improving microbial biodiversity in soil, land, and water.

Researchers diagnose disease with a drop of blood, a microscope and AI
Scientists have developed an automated, high-throughput system that relies on imaging droplets of biofluids for disease diagnosis in an attempt to reduce the number of consumables and equipment needed for biomedical testing.
NewsSmart toilet designs in Cambodia held promise, but a key piece was missing
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was missing: using it correctly.
NewsImpact of pasteurization on dairy calves’ gut microbiota: A study of milk feeding and early microbial colonization
A new study highlights the impact of pasteurization on microbial diversity in dairy calves, underlining the importance of balancing pathogen safety and microbial health. It suggests that while pasteurization prevents pathogen transmission, it also reduces beneficial microbial transfer.
NewsMachine learning tool can scan for signs of extraterrestrial life
A machine learning framework can distinguish molecules made by biological processes from those formed through non-biological processes and could be used to analyze samples returned by current and future planetary missions.
NewsFlower to fruit: tracking the changing fungal community on blueberry plants
A study identifies how fungal diversity changes over time and across tissue types in highbush blueberry, revealing dynamic transitions in the phyllosphere from buds to ripe fruits. Early-season buds and flowers harbor the highest fungal diversity, while unripe green fruits display the lowest.
NewsBiochar boosts clean energy output from food waste in novel two-stage digestion system
A new study from researchers at the University of Western Australia and Universitas Brawijaya has found that adding biochar to advanced food waste recycling systems can significantly increase the clean energy yields of hydrogen and methane. This breakthrough offers promising strategies for municipalities and industries aiming to turn food scraps ...
NewsManure digesters on farms carry limited benefits and potential harms
Manure digesters, touted as eco-friendly solutions for managing agricultural waste and reducing greenhouse gases, have limited capacity to reduce livestock-related greenhouse gas emissions, and entail potential hazards that may outweigh their benefits.

A scientist who harnesses bacteria to deliver green solutions has been named as one of the winners of the 2025 Tata Transformation Prize. Balasubramanian Gopal, PhD, Indian Institute of Science, has been named Sustainability Winner in the awards.
NewsA microbial blueprint for climate-smart cows
Recent research has shown that feeding cows red seaweed can dramatically cut the amount of methane that is produced and released into the environment. A new study sheds light on that process and reveals which microbes in the cow’s gut might help reduce methane.
NewsHepatitis E virus from rats can also infect humans in individual cases – a new zoonotic pathogen?
It has only been known for a few years that humans can also be infected with a variant of the hepatitis E virus that is usually prevalent in rats. Following reports of individual cases, mainly from Hong Kong and Spain, the first infection with ratHEV has now also been described in a patient from Germany.
NewsPig disease vaccine effectiveness linked to T cell response
A new study shows that the effectiveness of current vaccines against porcine reproductive and respiratory syndrome virus (PRRSV) is due to the response of T cells against the disease, rather than the production of antibodies. The work is an important step in identifying specific targets for vaccines on a rapidly mutating virus.
NewsMicrobial teamwork slashes uranium pollution in just 48 hours
A research team has developed a synthetic microbial consortium that completely reduces soluble uranium [U(VI)] to insoluble U(IV) within 48 hours, showing nearly twice the efficiency of a single-strain system. The study reveals how Shewanella oneidensis MR-1 and Pseudomonas aeruginosa LXZ1 cooperate to accelerate extracellular electron transfer (EET).
NewsAncient chemical clues reveal Earth’s earliest life 3.3 billion years ago
A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years earlier than previously thought. Researchers paired cutting-edge chemistry with artificial intelligence to reveal faint chemical “whispers” of biology locked inside ancient rocks.
NewsResearchers identify mangrove tree stems as previously underestimated methane source offsetting blue carbon benefits
A new study reveals that mangrove tree stems represent a significant yet previously underestimated source of methane. Additionally, stem emissions showed a strong correlation with soil methane fluxes, indicating that methane produced by anaerobic microbial activity in mangrove soils is transported upward through specialized aerenchyma tissues within the trees.
