Probing bacterial resistance to a class of natural antibiotics
Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system—the first line of defense against disease-causing microbes.
Scientists reveal how penicillin deals bacteria a devastating blow – work that may lead to new antibiotics
Penicillin, the wonder drug discovered in 1928, works in ways that are still mysterious almost a century later. One of the oldest and most widely used antibiotics, it attacks enzymes that build the bacterial ...
The nutritionists within: Firebugs depend on gut bacteria for vitamin supply
Microbial partners are important for the nutrition of many insects. They help detoxify and digest food, but also provide essential nutrients that insects need in order to survive. The European firebug Pyrrhocoris ...
Learning anti-microbial physics from cicada
(Phys.org) —Inspired by the wing structure of a small fly, an NPL-led research team developed nano-patterned surfaces that resist bacterial adhesion while supporting the growth of human cells.
Clean energy 'bio batteries' a step closer
Researchers from the University of East Anglia (UEA) are a step closer to enhancing the generation of clean energy from bacteria.
Thinking small to stop superbugs
With the help of cutting edge microscopy, new research at U of T Mississauga could help stop "superbugs" in their tracks.
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Water purification at the molecular level
(Phys.org) —Fracking for oil and gas is a dirty business. The process uses millions of gallons of water laced with chemicals and sand. Most of the contaminated water is trucked to treatment plants to be ...
Researchers discover how microbes build a powerful antibiotic
Researchers report in the journal Nature that they have made a breakthrough in understanding how a powerful antibiotic agent is made in nature. Their discovery solves a decades-old mystery, and opens up new ...
High-throughput method for sorting cells
UH Mānoa College of Engineering mechanical engineer Yi Zuo has developed a new, high-throughput method for sorting cells capable of separating 10 billion bacterial cells in 30 minutes.
Chemists modify antibiotic to vanquish resistant bacteria
Scientists at The Scripps Research Institute (TSRI) have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria.
New insights in survival strategies of bacteria
Bacteria are particularly ingenious when it comes to survival strategies. They often create a biofilm to protect themselves from a hostile environment, for example during treatment with antibiotics. A biofilm is a bacterial ...
How bacteria battle fluoride
He's not a dentist, but Christopher Miller is focused on fluoride. Two studies from his Brandeis University lab provide new insights into the mechanisms that allow bacteria to resist fluoride toxicity, information ...
Knowing how bacteria take out trash could lead to new antibiotics
A collaborative team of scientists including biochemist Peter Chien at the University of Massachusetts Amherst has reconstructed how bacteria tightly control their growth and division, a process known as ...
