US health authorities are investigating an E. coli outbreak connected to raw milk cheese. The CDC has published an advisory linking cases of the bacterial infection to cheese made from unpasteurized milk, and is working to identify the specific products and suppliers involved. Consumers are being urged to check for affected cheeses and to avoid unpasteurized dairy products, which carry a higher risk of contamination with dangerous bacteria.

New research reported by The Scientist suggests bacteria can learn and store memories in ways that resemble artificial neural networks. The findings point to memory-like behaviour in single-celled organisms without nervous systems, drawing comparisons between microbial adaptation and machine learning models. Scientists say the work could reshape understanding of how simple life forms process information and inspire new computing approaches.

Feverish babies admitted to hospital are often assumed to have a serious bacterial infection and are treated with antibiotics as a precaution. A new test that gauges whether an infection is bacterial or viral could reduce unnecessary antibiotic use in infants, helping doctors avoid overprescription and supporting efforts against antimicrobial resistance.

Health officials have linked an E.coli outbreak to raw milk cheese, prompting warnings to consumers about unpasteurized dairy products. The announcement is drawing attention to the ongoing risks of raw milk products, which can carry harmful bacteria not killed by pasteurization. Authorities are urging anyone who consumed raw milk cheese recently and developed symptoms to seek medical advice.

Researchers are highlighting efforts to combat infectious diseases and the growing threat of antibiotic resistance, according to a science news release. Antimicrobial resistance is a major global health concern, as bacteria increasingly evade existing drugs, prompting calls for new treatments and better stewardship of current antibiotics.

Scientists report that dormant, hibernating bacteria can persist in hospitals and even survive the conditions of outer space, making them hard to eradicate. However, maintaining this dormant state carries a high energy cost. Researchers say targeting that energetic weakness could offer a new way to eliminate these resilient bacteria, with implications for hospital infection control and our understanding of microbial survival in extreme environments.

Health officials in Georgia have reported one case of E. coli illness connected to an outbreak traced to raw milk cheese. The patient is the first person sickened in the state in this outbreak. Raw milk products are a known carrier of E. coli bacteria, and investigators are working to identify the source. The news has prompted renewed warnings about consuming unpasteurized dairy products.

Researchers have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. DNA analysis revealed these genetic pathways in the gill microbes, suggesting reef fish may host bacteria capable of producing nutrients in ways previously associated with deep-sea ecosystems rather than sunlit reefs.

Health officials have linked raw cheese to an E. coli outbreak that has made two children in San Diego County ill, according to local reporting. The cases have raised renewed attention on the risks of unpasteurized dairy products, which can carry harmful bacteria. Authorities are urging caution with raw cheese consumption as the investigation continues.

Health officials are investigating an E. coli outbreak linked to raw milk cheese that has sickened two children in San Diego County, California. The cases have raised renewed concerns about the safety of unpasteurized dairy products, which can carry harmful bacteria. Authorities are working to identify the source of the contamination and warn consumers about the risks of raw milk products.

A new finding reports that overlapping genes—genes whose sequences physically overlap on the genome—are subject to different evolutionary pressures depending on the organism. In bacteria, overlapping genes appear to evolve under one set of constraints, while in eukaryotes, or complex life, they follow another. The results suggest that genome architecture shapes how evolution acts on shared genetic material, challenging the assumption that overlapping genes obey universal rules across all living things.

A new study finds that roughly one in eight cancer cases worldwide is caused by infections. The finding highlights the role of viruses and bacteria such as HPV and H. pylori in triggering cancers, and points to prevention through vaccination and treatment of common infections as a major opportunity to reduce the global cancer burden.

A new study finds that roughly one in eight cancer cases worldwide are caused by infections, according to CBC News coverage. The finding highlights the role of viruses and bacteria in cancer development and has prompted discussion about prevention, vaccination, and screening efforts globally.
