“Bacterial suicide squad” recruits and activates innate and adaptive antitumor immune responses

Combining discoveries in cancer immunology with sophisticated genetic engineering, Columbia University researchers have created a sort of "bacterial suicide squad" that targets tumors, attracting the host's own immune cells to the cancer to destroy it. The new work, published today in Science Advances, marks a major step forward in efforts to enlist non-pathogenic bacteria to combat cancer.

Analyzing microscopic chalk disks coccoliths formed by the marine algae

Under the guidance of Rutgers University, a research group learning about virus-host interactions of worldwide abundant and armor-plated marine algae, Emiliania huxleyi, has discovered that the circular and chalk plates produced by the algae have the potential to serve as catalysts for viral infection.

Effective and faster methodology detects RNA viruses based on the triplex-forming probe technology

Experts from the University of Barcelona, the Institute for Advanced Chemistry of Catalonia (IQAC-CSIC), the Institute of Microelectronics of Barcelona (IMB-CNM-CSIC) and the Aragon Nanoscience and Materials Institute of Aragon (INMA) -;a joint institute of the CSIC and the University of Zaragoza-; have developed a new method to detect RNA viruses based on the triplex-forming probe technology.

Epigenetics and the symbiosis between trees and fungi

To share nutrients and enhance their capacity for environmental adaptability, tree roots frequently collaborate with fungi. Although this interaction is mutually beneficial (namely, ectomycorrhizae), the biological mechanisms at play have not yet been completely analyzed.

Limiting antibiotic use in livestock associated with reduction in antibiotic-resistant infection

A California policy restricting antibiotic use in animals raised for food is associated with a reduction in one type of antibiotic-resistant infection in people in the state, according to a new study published today in the journal Environmental Health Perspectives.

Modifying patients' intestinal flora could be a new therapeutic approach for colon cancer

Studies show that certain bacteria may contribute to the development of colorectal cancer by producing toxins that may damage colon cells or cause an accumulation of DNA mutations and/or intestinal inflammation.

Study reveals how chloroplast ATP synthase regulates ATP production in organisms

ATP, the compound essential for the functioning of photosynthetic organisms such as plants, algae, and cyanobacteria, is produced by an enzyme called "chloroplast ATP synthase" (CFoCF1).

Removing antibiotics from wastewater with biochar

Farmers must cultivate a large number of crops to feed the world’s expanding population. Water is necessary for crops to grow and thrive, and 70% of the freshwater consumed globally is utilized to irrigate crops.

Role of probiotics and functional materials in the treatment of intestinal inflammation

Maintenance of sulfomucin is a key end point in the treatment of diarrhea and inflammatory bowel disease (IBD). However, the mechanism underlying the microbial sense to sulfomucin are poorly understood, and to date, there are no therapies targeting the secretion and maturation of sulfomucin in IBD. Considering the important role of gut microbiota in host immune regulation, maintain sulfomucin by modulating the gut microbiota is inspired.

Novel molecule prevents cells from infection with SARS-COV-2

The virus that causes COVID-19, called SARS-CoV-2, uses its spike protein in order to stick to and infect our cells. The final step for the virus to enter our cells is for part of its spike protein to act like a twist tie, forcing the host cell's outer membrane to fuse with the virus.

Identifying antimicrobials that effectively treat AMR infections

In a potential game changer for the treatment of superbugs, a new class of antibiotics was developed that cured mice infected with bacteria deemed nearly "untreatable" in humans -; and resistance to the drug was virtually undetectable.

AutoPLP helps detect mutating pathogenic variants quickly and accurately

As we now know from our experience with the COVID-19 pandemic, the microbes responsible for some infections can rapidly mutate into variants that evade detection and treatment.

Effect of prune supplementation on the gut microbiome of postmenopausal women

New research published in the journal Food & Function indicates that daily prune consumption may improve the gut fecal microbiome of postmenopausal women. The fecal microbiome – the ecosystem of microorganisms found in one's fecal matter – reflects an individual's overall gut health. Results from the study showed notable enrichment in bacteria from the family Lachnospiraceae. This group of bacteria has been associated with an ability to decrease inflammatory markers in the body and help maintain the integrity of the gut barrier.
