New antibiotic found in bacteria in a worm in an insect egg

BSIP / Universal Images Group The last antibiotics produced against Gram-negative bacteria – which tend to be more dangerous – were developed in the 1960s. Thanks to the increasing resistance to antibiotics, we need more. But instead of bothering to do our own, scientists have been looking for other species that may have to kill the same bacteria we do …

In order to survive in the human gut, bacteria need a genetic "passcode"

Abstract Bacteria need a number of specialized genes to live in the human gut – and the composition of these genes varies from person to person. Therefore, efforts may need to be made to improve the health of the microbiome, including next-generation probiotics. The human gut is a dangerous place to exclude toxins to deter microbial invaders. However, every human's …

This microbe spreads antibiotic resistance to other bacteria

Antibiotics Resistance Spread Quickly Around the World . If infectious bacteria mutate in a certain way and then multiply, they can become resistant to even the strongest drugs. However, research has revealed a worrying alternative to the spread of antibiotic resistance: an organism that transfers its resistance to other living bacteria. In June 2012, a 35-year-old man from São Paulo …

This fashionable ski jacket is made of spider silk, which is bred by bacteria

In the future, synthetic biology will not only change the way we treat diseases or treat waste, but also how we dress. For example, a Japanese biotech company just announced the world's first spider silk jacket made from genetically engineered bacteria. Credit: Spiber. Although spider silk is apparently fragile, it is one of the hardest materials in nature. Pound-per-pound protein …

Astronomers want to use bacteria to break down space rock

Space Bugs Astronomers have just sent 18 different bacterial strains to the International Space Station. They should not contaminate the already grossly circulating research center, but rather determine if it is a mineral – leaching microbes could help astronauts mine space rocks on future missions, reported Space.com , If the so-called BioRock experiment fails to materialize, researchers behind the experiment …

The scissors stick – otherwise bacteria use CRISPR / Cas9

Credit: CC0 Public Domain CRISPR / Cas9 is a hot topic in biotechnology today as it is a precise tool for gene manipulation. Before people used it again, CRISPR / Cas9 was a type of internal immune system that defends bacteria against phages or viruses that infect bacteria by cutting the DNA of phages. Scientists at the Emory University School …

Bacteria from your gut can be the key to keep going

The researchers found the bacteria after examining the stern of 10 Boston Marathon runners. In order to gain energy for itself, Veillonella degrades lactic acid, which is formed to a greater extent in particularly demanding sports. To determine if the bacteria made a difference, the researchers isolated a strain of it, inserted it into 16 mice, and then put it …

Medicinal plants used during the US Civil War are surprisingly good at fighting bacteria

Leaves and bales of white oak were used during the US Civil War for the production of herbal antiseptics. [19659003] Image: Stephen Nowland, Emory University Conventional medicines were scarce during the Civil War, and the Confederation desperately turned to plant alternatives. Recent research suggests that some of these remedies can actually fight infections quite well – a finding that could …

Researchers produce artificial mother-of-pearl with bacteria

This abalone shell is a natural form of mother-of-pearl – also called mother-of-pearl – an exceptionally tough material found in shells and pearls. Rochester biologists have developed an innovative way to make mother-of-pearl in the lab – and maybe on the moon. Picture credits: University of Rochester / J. Adam Fenster The strongest synthetic materials are often those that intentionally …
