Scientists completed the first comprehensive survey of microscopic life in Australia's Great Barrier Reef, discovering hundreds of previously unknown bacterial species and thousands of viruses. This creates a new database to monitor reef health and understand how these crucial microbes respond to environmental pressures.
Anthony Albanese will announce expanded paid work experience in healthcare at Labor's national conference. Australia's military is training in old-school navigation for cyber-attack resilience, Penny Wong will warn China, and a national emergency siren test is scheduled. Global news includes an oil surge, France's heatwave deaths, and pressure on Zelenskyy.
Scientists have comprehensively mapped the Great Barrier Reef's microbiome, identifying over 360,000 distinct viruses and more than 500 new bacterial species. This research, led by the University of Queensland and AIMS, offers a new tool for monitoring reef health and climate change impacts.
Starlet sea anemones use specialized mobile nematosomes and the cJun gene to selectively identify and destroy harmful bacteria while preserving beneficial microbes, challenging the belief that targeted immunity is exclusive to vertebrates' adaptive immune systems and pushing back its evolutionary timeline.
Researchers from Heinrich Heine University Düsseldorf and Kiel University discovered that the starlet sea anemone, Nematostella vectensis, uses specialized mobile cell structures called nematosomes to selectively identify and destroy harmful bacteria while preserving beneficial ones. This challenges the long-held assumption that targeted immune discrimination requires the complex adaptive immune system of vertebrates, pushing back the evolutionary timeline for such capabilities by hundreds of millions of years.
Virginia Tech research reveals nanoplastics, tiny plastic fragments, can strengthen bacterial biofilms and activate viruses in drinking water systems. This makes harmful microbes more resistant to disinfection, posing a challenge for water treatment and public health by fostering "superbugs" and increasing maintenance complexity.
Researchers have developed a simpler, more cost-effective method to measure DNA-bound phosphorus in soil microbes. This biologically active nutrient form is linked to microbial activity and soil recycling, offering insights for sustainable agriculture and improved soil fertility.
Saharan dust storms are increasingly intense, depositing microorganisms over Europe. A study in Portugal found bacteria in dust that could act as natural fertilizers, potentially benefiting crop growth, especially in vineyards.
A new study on cockroach genomes reveals that horizontal gene transfer, the incorporation of DNA from one species into another, is surprisingly common in multicellular animals. While previously thought rare, findings suggest this process may contribute more to animal genome diversity than previously understood.
A new study reveals that romantic partners share about 44% of their oral microbiome and 19% of their gut microbiome. Researchers analyzed data from 207 households in Italy and Fiji, quantifying microbe transmission rates and identifying potential links between transmissible microbes and health risks like Type 2 diabetes.
Scientists have discovered that some microbes found on and inside Ötzi the Iceman, a 5,300-year-old mummy, may still be alive. A new study analyzed the mummy's DNA, identifying fungal species adapted to cold environments that likely colonized his body before he died and froze. The research suggests these microbes could remain active for thousands of years, offering insights into ancient human microbiomes and posing challenges for preserving organic remains.
Ötzi, the 5,300-year-old Copper Age mummy, hosts a mix of ancient and modern microbes, including cold-adapted yeasts and bacteria that have survived for millennia or been introduced recently.
A study of the 5300-year-old 'Iceman Ötzi' found ancient and modern microbes, some potentially metabolically active. Researchers identified bacteria and fungi, including cold-adapted yeasts, suggesting some microbes may survive and even thrive under current preservation conditions, though no damage to the remains has been observed.
UCL researchers discovered signature changes in gut microbiome that identify people at greater risk of Parkinson's disease before symptoms develop. The study found 176 gut microbe species differed in Parkinson's patients, with similar changes in those with genetic risk but no symptoms. The findings raise hopes for dietary interventions and treatments that reshape the microbiome to prevent or delay the disease.
