In a new study, researchers have determined through both statistical analysis and in experiments that soil pH is a driver of microbial community composition – but that the need to address toxicity released during nitrogen cycling ultimately shapes the final microbial community.
A series of seemingly small processes helps carry carbon dioxide from the ocean’s surface to the deep sea, where it can be stored away for decades.
Gazing out on a freshwater pond, you may see tiny green plants with oval shaped leaves floating in clusters. In overgrown ponds, these plants coat the water’s surface. These plants – called duckweed or water lentils – can grow so fast that they can double their numbers in just one to two days.
Mold can survive the harshest of environments, so to stop harmful spores from growing on future space stations, a new study suggests a novel way to prevent its spread.
Increased capabilities in the human-occupied submersible Alvin open a window on a rarely seen behavior
Alexander Chase and colleagues collect samples from Earth’s oceans using SMIRC, which could be the first step in uncovering compounds that lead to next-generation antibiotics.
A new study has provided critical insights into Gulf War illness, a chronic condition affecting veterans deployed during the 1990–1991 Gulf War. The findings are the most comprehensive to date that establishes an association between gut microbiome imbalance and Gulf War veterans, paving the way for new treatments.
A new Cedars-Sinai study shows how microorganisms in the human gut can trigger constipation in some people.
Ancient viruses preserved in glacial ice hold valuable information about changes in Earth’s climate, a new study suggests.
Biologists find new ways to encourage the plastic-producing power of purple microbes.
A new study has found a symbiotic relationship that has evolved between Darwin’s favourite carnivorous plant and a specific type of fungus which lives inside it and helps it digest its prey. Researchers from Loughborough, Taiwan and USA have shown that Acrodontium crateriforme, a fungus that thrives in the acidic conditions on the leaves, improves the digestion of the Drosera species of carnivorous plant – otherwise known as a sundew (pictured above), and once described by Charles Darwin as, "a wonderful plant… I care more about Drosera than the origin of all the species." The fungus lives in a sticky secretion at the end of tentacles on the leaves. Its enzymes work with the plant's digestive processes to help it break down the prey – small bugs and insects. The findings show that teamwork between plants and fungi may contribute to the evolution of carnivorous plants.
UC Davis Health researchers has discovered a novel bioelectrical mechanism pathogens like Salmonella use to find entry points in the gut lining that would allow them to pass and cause infection.
The University of Texas MD Anderson Cancer Center today was awarded nine grants totaling over $21.4 million from the Cancer Prevention and Research Institute of Texas (CPRIT) in support of two new core facilities, faculty recruitment and groundbreaking cancer research across all areas of the institution.
For nearly a century, scientists have waged war on antibiotic-resistant microbes. Michigan State University researchers say they’ve found a new way to prevent it – by unleashing “DNA scavengers” in wastewater treatment plants.
Among patients undergoing lumbar spinal fusion, the presence of Modic changes is associated with differences in microbial diversity and metabolites in the lumbar cartilaginous endplates (LCEPs), reports a study in The Journal of Bone & Joint Surgery. The journal is published in the Lippincott portfolio by Wolters Kluwer.
Cleveland Clinic researchers have made a significant discovery about how the gut microbiome interacts with cells to cause cardiovascular disease.
A global study has uncovered a strong link between the microbes found in sewage and a country’s economic conditions. By analyzing samples from 60 countries, researchers found that the diversity of human-related microbes varies widely, influenced by factors such as export levels and social security. This study demonstrates how sewage can be a valuable tool for monitoring public health and assessing the impact of economic conditions on microbial communities worldwide.
Giving probiotics to pregnant mice can enhance both the immune system and behavior of the mothers and their offspring, according to a new study led by The Ohio State University Wexner Medical Center and College of Medicine.
A new Cleveland Clinic study has identified diet-derived molecules called metabolites as main drivers of young-onset colorectal cancer risk, especially those associated with red and processed meat. The NPJ Precision Oncology report, which analyzed metabolite and microbiome datasets, highlighted that one of the best ways a younger (<60 years) adult can prevent colorectal cancer is to discuss their diet with their doctor.
A new technique developed at Berkeley Lab will make it much easier for researchers to discover the traits or activities encoded by genes of unknown function in microbes, a key step toward understanding the roles and impact of individual species within the planet’s diverse microbiomes.
