Researchers create glowing probe to track ocean microbe sugar breakdown
A team of scientists has invented a fluorescent molecular probe that lights up when marine microbes degrade sugars, revealing key processes in the ocean's carbon cycle. This tool allows real-time observation of how algae and bacteria interact in breaking down complex carbohydrates. The breakthrough, detailed in the Journal of the American Chemical Society, promises deeper insights into carbon storage and release in marine ecosystems.
Harvard study links gut bacteria to lower anxiety levels
AI에 의해 보고됨
Researchers at Harvard University have identified specific gut microbiome compositions associated with reduced anxiety in humans. The two-year study, published today, strengthens evidence for the gut-brain connection. This discovery opens doors to microbiome-based mental health interventions.
Researchers discover new carbon storage method in soils
Scientists have identified a novel mechanism in soil microbes that enhances long-term carbon sequestration. This breakthrough could help mitigate climate change by locking away more atmospheric CO2. The findings were detailed in a study published on October 1, 2025.
Scientists revive microbes dormant in permafrost for 46,000 years
Researchers have successfully awakened ancient microbes trapped in Siberian permafrost for up to 46,000 years. The experiment demonstrates the remarkable resilience of these microorganisms. The findings, published in Nature Communications, raise concerns about potential pathogen release as permafrost thaws due to climate change.
Stratospheric microbes' pigments could detect life on exoplanets
Scientists have measured the colors of microbes living high in Earth's atmosphere, revealing pigments that protect against UV light. These findings suggest that similar biosignatures in exoplanet clouds could indicate alien life. The research provides reference spectra for future astronomical observations.
