For the study, Riekenberg and colleagues looked at the chemical variations in the isotopes of nitrogen. There are two predominate forms of nitrogen, 'nitrogen-14' and the heavier version, 'nitrogen-15'.
Northern peatlands contain one third of the Earth’s soil carbon, making them important for carbon storage. In northern peatlands, carbon losses from soil during the winter can exceed carbon storage during the warm growing season, primarily because of the activity of microbes. To better understand how microbes interact in peatland soils during the winter months, this study incubated Arctic peat soils under winter conditions, then analyzed the microbes to understand how the microbes released carbon dioxide.
In an intensive look at the effects of the virus causing COVID-19 on patients’ microbiome – the collection of microorganisms that live in and on the human body – Rutgers scientists found that acute infection disrupts a healthy balance between good and bad microbes in the gut, especially with antibiotic treatment.
An international team of scientists investigating transmission of a deadly drug resistant bacteria that rivals MRSA, has found that whilst the bugs are found in livestock, pets and the wider environment, they are rarely transmitted to humans through this route.
Members of Skryabin Institute of bioengineering and Winogradsky Institute of Microbiology, that are the part of Federal Research Center “Biotechnology", Russian Academy of Sciences (Moscow) in the course of working on the project of Russian Scientific Foundation selected samples of activated sludge from nine large waste treatment plants of Moscow and analyzed genes 16S rRNA of their microbal inhabitants.

Current advances include a promising targeted therapy combination for patients with relapsed/refractory acute myeloid leukemia (AML), a link between the gut microbiome and therapy-related neutropenic fever, a novel therapeutic target for immunotherapy-related colitis, a telementoring model for training providers on cervical cancer prevention in limited-resource areas, a new understanding of the prognostic value of RUNX1 mutations in AML, and insights into the effects of opioid use on the pain sensitivity pathway.
Millions of antibiotics are prescribed every year. Although they can be incredibly effective at treating infections, antibiotics usually do not solely target the bacteria that is causing infection.
In a new study in Nature, researchers at Children’s Hospital of Philadelphia (CHOP) have found that Enterococcus – an antibiotic-resistant, opportunistic pathogen – works together with C. difficile, reshaping and enhancing the metabolic environment in the gut so that C. difficile can thrive.
Two new studies from researchers at Fred Hutchinson Cancer Center in Seattle reveal how bacteria infiltrate tumors and could be helping tumors progress and spread and suggest a link between oral health and cancer, as microbes in the mouth are associated with cancers elsewhere in the body. The two papers – one published Nov. 15 in Cell Reports and the other published Nov. 16 in Nature – focus on an oral bacterium called Fusobacterium nucleatum, which has been linked to colorectal cancer.
A new study by Penn State College of Medicine finds that small molecules found in most humans’ breast milk may reduce the likelihood of infants developing allergic conditions.
A brisk walk for 20 minutes a day may not sound like much, but it could make a big difference for colorectal cancer patients. Regular physical activity reduces inflammation by improving the gut microbiome of patients, including patients who are obese, scientists at Huntsman Cancer Institute found. They researched the impact of exercise on the gut microbiome, the trillions of bacteria that live in our digestive system. Investigators found moderate exercise improved outcomes in colorectal cancer, the third most common cancer in the United States, excluding skin cancers. Scientists explain why their findings are so significant.

Antibiotics routinely used in ovarian cancer care indiscriminately kill gut bacteria, leading to faster cancer progression and lower survival rates, according to recent Cleveland Clinic research.
Two weeks of eating a diet heavy in tomatoes increased the diversity of gut microbes and altered gut bacteria toward a more favorable profile in young pigs. After observing these results with a short-term intervention, the research team plans to progress to similar studies in people.
James McKinlay is an associate professor of biology at Indiana University. His group used genetics, analytical chemistry, and computational modeling to identify factors that determine hydrogen gas production levels. More broadly, we identified factors that govern cooperative relationships between microbes.

In Star Trek, the Borg are a ruthless, hive-minded collective that assimilate other beings with the intent of taking over the galaxy. Here on nonfictional planet Earth, Borgs are DNA packages that could help humans fight climate change.
The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they’re simultaneously infected by viruses and face attack from nearby predators, new research has found.
As greenhouse gases bubble up across the rapidly thawing Arctic, Sandia National Laboratories researchers are trying to identify other trace gases from soil microbes that could shed some light on what is occurring biologically in melting permafrost in the Arctic.Sandia bioengineer Chuck Smallwood and his team recently spent five days collecting lakebed soil and gas samples.

A method for detecting intraspecies genomic diversity of uncultivated bacterial DNA has been developed. This enhanced MAG method's ability to detect previously overlooked variations focuses on the DNA sequence and structural traits of the genome. The spectrum of microdiversity in environmental bacterial genomes has been found to be broader than expected.
The latest dinosaur discoveries in the Dinosaurs channel on Newswise.
New UCLA-led research suggests certain gut bacteria -- including one that is essential for a healthy gut microbiome – differ between people who go on to acquire HIV infection compared to those who have not become infected. The findings, published in the peer-reviewed journal eBioMedicine, suggest that the gut microbiome could contribute to one’s risk for HIV infection, said study lead Dr.
An international team of scientists, co-led by researchers at the University of California San Diego School of Medicine, has created the first pan-cancer mycobiome atlas — a survey of 35 types of cancer and their associated fungi
RUDN agronomists have studied the microbial community of water and soil in the Arctic. In recent years, this region has been increasingly polluted with oil products. Some of the detected microorganisms are able to “digest” oil hydrocarbons that are dangerous for the environment. Perhaps in the future they will help clean up the region.
The banana borer Cosmopolites sordidus and the disease Fusarium wilt, caused by the soil-borne fungus Fusarium oxysporum, are among the most harmful pests that threaten the livelihoods of banana growers, who face major challenges in attempting to control them.
Stress has been linked to all sorts of serious health issues, from insomnia to high blood pressure, obesity and even heart disease. But it’s generally acknowledged that some stress can also be helpful, like when someone’s chasing a work deadline. But what if some level of stress can actually protect the body? A new study by researchers at the Case Western Reserve University School of Medicine, with findings published Sept. 26 in Proceedings of the National Academy of Sciences, suggests the immune system may benefit from a measure of stress.
