Biomimicry of chemically oscillating mobile catalytic capsules

The complexity of life on earth was derived from simplicity: from the first protocells to the growth of any organism, individual cells aggregate into basic clumps and then form more complex structures.

OSU researchers study quorum sensing in a gram-negative bacterium that displays social behaviors

Oregon State University scientists have identified proteins that prevent a bacterial cell from becoming misguided by its own messaging, allowing it to instead wait for collective communication from its group.

A new approach for treating multiple-drug resistant bacteria

Antibiotic-resistant hospital pathogens are not to be underestimated as a health risk. A research team has now introduced a new approach for treating multiple-drug resistant Staphylococcus in the journal Angewandte Chemie.

New molecule extracted from the leaves of chestnut tree neutralizes staph bacteria

Scientists isolated a molecule, extracted from the leaves of the European chestnut tree, with the power to neutralize dangerous, drug-resistant staph bacteria. Frontiers in Pharmacology published the finding, led by scientists at Emory University.

Synthetic biology can help create complex embryo

Richard Feynman, one of the most respected physicists of the twentieth century, said "What I cannot create, I do not understand". Not surprisingly, many physicists and mathematicians have observed fundamental biological processes with the aim of precisely identifying the minimum ingredients that could generate them. One such example are the patterns of nature observed by Alan Turing.

Study identifies potential high-risk virulent clones circulating in European hospitals

UAB researchers, based on a collection of clinical isolates from several countries, have established a link between the cell-to-cell communication system (the quorum sensing) and the virulence and resistance phenotypes in Stenotrophomonas maltophilia.

Novel drug to arrest antibiotic resistance by preventing micro-evolution

Desperate times need desperate measures. Accordingly, scientists, today published a new study in the journal Cell Host and Microbe in March 2020, showing that drugs that prevent the acquisition of DNA-borne antibiotic resistance traits from their surroundings by bacteria can stop mice from becoming resistant to the action of the antibiotics.

Princeton's Bonnie Bassler awarded the 2020 Gruber Genetics Prize

The 2020 Gruber Genetics Prize is being awarded to geneticist Bonnie Bassler, Ph.D. of Princeton University and the Howard Hughes Medical Institute, for her groundbreaking work on how bacteria "talk" to each other using molecular "languages."

A receptor helps body cells to spot communication amongst bacteria

Bacterial infection does not automatically lead to illness; many germs only become dangerous when they occur in large numbers.

New technique for autonomous coordination of cell subpopulations

For years, scientists have explored ways to alter the cells of microorganisms in efforts to improve how a wide range of products are made - including medicines, fuels, and even beer.

Mutant bacterial receptor could help identify therapeutic compounds that inhibit quorum sensing

Researchers have developed a new mutant version of a receptor used by a bacterial pathogen for a chemical communication process called quorum sensing, according to a study published June 13 in the open-access journal PLOS Pathogens by Bonnie Bassler of Princeton University, and colleagues.

Microbiologists uncover how antibiotics help spread resistance

Bacteria can become insensitive to antibiotics by picking up resistance genes from the environment. Unfortunately for patients, the stress response induced by antibiotics activates competence, the ability of cells to take up and integrate foreign DNA, in microorganisms.
