NewsHeme-based sulfide sensing in bacteria: a new target for antibiotics
Heme binding to a bacterial transcription factor is critical for hydrogen sulfide (H₂S) signaling, a new study reveals. Heme binding promotes the reaction of H₂S with the transcription factor, leading to structural changes that can regulate stress tolerance in bacteria.

NewsGame-changing biotech for engineering pathogen-resistant crops
Researchers have identified an ancient protein that has the potential to help defend plants against tens of thousands of different bacteria and other pathogens. Dubbed “SCORE”, this receptor detects cold-shock protein—variations of which are found in more than 85% of known bacteria, as well as fungi and insects.

NewsBiodegradable PET alternative bioproduced at unprecedented levels
The PET-alternative PDCA is biodegradable and has superior physical properties. A team of bioengineers has engineered E. coli bacteria to produce the compound from glucose at unprecedented levels and without byproducts — and opened up a realm of possibilities for the future of bioengineering.

NewsOne dose of antibiotic treats early syphilis as well as three doses
Researchers have found that a single injection of the antibiotic benzathine penicillin G (BPG) successfully treated early syphilis just as well as the three-injection regimen used by many clinicians. These findings from a late-stage clinical trial suggest the second and third doses of conventional BPG therapy do not provide a health benefit.

NewsThe cling of doom: How staph bacteria latch onto human skin
Scientists have discovered the strongest natural protein bond ever recorded, explaining how Staphylococcus aureus clings so tightly to human skin and pointing to new ways to fight antibiotic resistance.

NewsCARB-X to support lower respiratory tract infection diagnostic by Zeteo
CARB-X has awarded Zeteo Tech, Inc. US$1M to execute a workplan for its noninvasive diagnostic platform that aims to evaluate whether exhaled breath can diagnose lower respiratory tract infections (LRTIs) in high-risk populations within critical care environments.

NewsBacteria that ‘shine a light’ on microplastic pollution
Researchers have developed a living sensor that attaches to plastic and produces green fluorescence. In an initial test on real-world water samples, the biosensor could easily detect environmentally relevant levels of microplastics.

NewsResearch team on quest to engineer computing systems from living cells
A research team has received a $1.99 million grant to lead research on engineered bacterial consortia that could form the basis of biological computing systems. They aim to integrate microbial sensing and communication with electronic networks, paving the way for computing systems constructed from living cells instead of traditional silicon-based hardware.

NewsBacteria rewire digestive systems to turn plant waste into power
A new study shows that Pseudomonas putida, a common soil bacterium, completely reorganizes its metabolism to thrive on complex carbons from lignin. By slowing down some metabolic pathways while accelerating others, the bacterium manages to extract energy from lignin without exhausting itself.

NewsZoo poo might hold the secrets to new medical treatments
Scientists are hoping the collection of poo from tigers, elephants, giraffes and other exotic animals, could contain the secret to finding new medical treatments. Although a waste product to the animals, hidden amongst it are thousands of phages which are potentially capable of fighting bacterial infections.

NewsUnlocking how bacteria bounce back after antibiotics
A groundbreaking study has uncovered how Escherichia coli (E. coli) persister bacteria survive antibiotics by protecting their genetic instructions. The work offers new hope for tackling chronic, recurring infections.

NewsLess is more: Gene loss drives adaptive evolution of a pandemic bacterium
A study reveals a surprising evolutionary insight: sometimes, losing genes rather than gaining them can help bacterial pathogens survive and thrive. The research focused on Vibrio parahaemolyticus, a bacterium behind many of the seafood-related infections worldwide.

NewsAncient mammoth remains yield the world’s oldest host-associated bacterial DNA
An international team has uncovered microbial DNA preserved in woolly and steppe mammoth remains dating back more than one million years. The analyses reveal some of the world’s oldest microbial DNA ever recovered, as well as the identification of bacteria that possibly caused disease in mammoths.

NewsTiny ocean partnership between algae and bacteria reveals secrets of evolution
The microscopic alliance between algae and bacteria offers rare, step-by-step snapshots of how bacteria lose genes and adapt to increasing host dependence, a new study shows.

NewsChronic wound infection model is much closer to real life - and cuts back on animal testing
Thousands of lab animals are used every year to test wound treatments. But one lab in Wales is pointing the way towards a more humane model of research, with the work it is carrying out on in vitro/animal replacement models.

NewsMicrobiologists uncover bacteria that remove toxic sulfide and use iron minerals for growth
An international team of scientists has discovered a new microbial metabolism: so-called MISO bacteria “breathe” iron minerals by oxidizing toxic sulfide. The previously unknown biological process sees versatile microbes remove toxic sulfide and use it for their growth.

NewsBacteria survive dust storms and introduce new genetic traits into our air
Bacterial communities carried from Africa to Israel survive their airborne journey, arriving with genes that may affect human health and the environment, a new study reveals.

NewsBroad-specificity enzyme targets glycans from across the kingdoms of life
Researchers have found a new enzyme that has a much broader specificity than the leading alternatives. This analysis resulted in the identification of the PNGaseL enzyme taken from Flavobacterium akiainvivens, which is a microbe isolated from decaying wood of a Hawai’ian plant.

NewsStudy finds significant health benefits from gut microbes transfer
A cohort of overweight teens who received fecal transfer eight years ago were found to have reduced risk for a series of metabolic changes which can lead to heart disease, stroke and diabetes, compared with the participants who received the placebo.
