A study has identified a therapy that can penetrate the slime that such infections use to protect themselves from antibiotics. Scientists showed that an antimicrobial peptide from cows has potential for treating incurable infections from the bacterium Klebsiella pneumoniae. The bacteria, commonly found in the intestines, is usually harmless. It becomes a health hazard when it enters other parts of the body and can cause pneumonia, urinary tract and wound infections. Those at highest risk include seniors and patients with other health problems such as diabetes, cancer, kidney failure and liver disease.

A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. Microbiologists have shown this for the very first time in a specific group of parasitic microbes, so-called DPANN archea. Their study shows that these archaea are very 'picky eaters', which might drive their hosts to change the menu.

Researchers uncover why some homes in rural Madagascar where bubonic plague is endemic are infested with fleas. Based on their findings, they recommend ways to reduce the flea populations and their impact on human health.

Viruses known as 'jumbo' phages are seen as a potential tool against deadly bacterial infections. But scientists must first decipher the extraordinary makeup of these mysterious viruses. Researchers have now uncovered a key piece of jumbo phage development that helps them counter bacteria.

Scientists are harnessing cells to make new types of materials that can grow, repair themselves and even respond to their environment. These solid 'engineered living materials' are made by embedding cells in an inanimate matrix that's formed in a desired shape. Now, researchers have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.

Researchers changed the composition of the gut microbiota in male mice through common antibiotics, inducing a condition called dysbiosis, and found that: - Mouse pups sired by a dysbiotic father show significantly lower birth weight, and have increased risk of growth disorders and postnatal mortality.

Conventional plant regeneration approaches by cell culture require the external application of plant growth regulators, including hormones. However, optimizing culture conditions can be laborious. Now, researchers have developed a novel plant regeneration system that omits the need for hormone application by genetically regulating the expression of genes that control plant cell differentiation. Their work holds significant potential in the development of genetically modified plants in a simpler and cost-effective manner.

NASA's James Webb Space Telescope has captured the sharpest infrared images to date of a zoomed-in portion of one of the most distinctive objects in our skies, the Horsehead Nebula. These observations show the top of the 'horse's mane' or edge of this iconic nebula in a whole new light, capturing the region's complexity with unprecedented spatial resolution.

Researchers have achieved a breakthrough in understanding how genetic drivers influence the evolution of a specific photosynthesis mechanism in Tillandsia (air plants). This sheds light on the complex actions that cause plant adaptation and ecological diversity.

3D microscopes are used in applications from the life sciences to semiconductor manufacturing. Now engineers are developing patented and patent-pending innovations making them work faster to capture even more 3D images and less expensive to manufacture.

Computer simulations by astronomers support the idea that dark matter -- matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe -- exists, according to the researchers.

Many bacteria produce substances to gain an advantage over competitors in their highly competitive natural environment. Researchers have discovered a new so-called lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and acts specifically against their main competitors there, the corynebacteria. This specificity is presumably mediated by a very special mechanism of action, which the researchers were able to decipher in detail.

Researchers report on the molecular assembly of one of the most common anti-phage systems -- from the family of proteins called Gabija -- that is estimated to be used by at least 8.5%, and up to 18%, of all bacteria species on Earth.
