Enhancing microbe memory to better upcycle excess CO₂

While some microbes can make people sick or spoil food, others are critical for survival. These tiny organisms can also be engineered to make specific molecules. Researchers reporting in ACS Sustainable Chemistry & Engineering ...

AI tool maps out cell metabolism with precision

Understanding how cells process nutrients and produce energy—collectively known as metabolism—is essential in biology. Modern biology generates large datasets on various cellular activities, but integrating and analyzing ...

Novel probiotics identified in traditional Brazilian cheeses

Research conducted at the Center for Dairy Technology (Tecnolat) in Campinas, São Paulo state, Brazil, has identified lactic acid bacteria (LAB) that have probiotic properties and are beneficial to human health in samples ...

Shedding light on the mechanism of yeast DNA repair

DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can ...

Compounds from nucleic acids in food show anticancer effects

When people eat, they ingest the nucleic acids that reside in all living things. The compounds in these acids could inhibit the growth of cancer cells, according to findings published in PLOS ONE by Osaka Metropolitan University ...

Study reveals how some bacterial infections become chronic

In the early 1900s, a cook named Mary Mallon, better known as "Typhoid Mary," spread Salmonella Typhi, the causative agent of typhoid fever, to dozens of her patrons even though she showed no symptoms. Many people today harbor ...

How archaea toggle the nitrogen-uptake switch to avoid overeating

By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists from the Max Planck Institute for Marine Microbiology now reveal how some methanogenic archaea manage to ...
