NewsIn extensive sequencing study, scientists find few links between cancer and microbiome
Scientists say a study that sequenced human cancers found far less microbial DNA sequences than earlier studies reported in the same cancer tissue samples.

NewsConnection among gut fungi, genetics and disease risk in humans identified
A novel genome-wide association study sheds light on the human genetic determinants of the fungal component of the human microbiome and their relation to chronic disease.

NewsFighting extinction, coral reefs show signs of adapting to warming seas
By studying how six months of elevated ocean temperatures would affect a species of coral from the northern Red Sea, scientists found that although these organisms can certainly survive in conditions that mimic future warming trends, they don’t thrive.

NewsBroccoli seeds can spread resistance to multiple fungicides
Researchers who screened commercial broccoli seeds for Alternaria brassicicola, a fungal pathogen, found that seeds can harbor A. brassicicola and can spread resistance to multiple fungicides. Based on the findings, the researchers developed a faster way for detecting and monitoring fungicide resistance.

NewsGray seals perplex scientists with lack of response to flu infection
Something strange happens when two kinds of seals living in the waters around Cape Cod get infected with influenza – harbor seals get sick but gray seals don’t. This perplexing phenomenon led scientists to investigate if a difference in a piece of the immune system called cytokines could be responsible for this difference.

NewsProtein discovery gives new hope for longer COVID protection
Scientists have discovered that the body’s immune system strongly reacts to an internal protein from SARS-CoV-2, the virus that causes COVID-19, which mutates less frequently than the surface-spike protein currently targeted by vaccines.

NewsAre probiotics worth the cost to prevent infection after a colon removal surgery?
A study found that taking an 8-strain probiotic daily may reduce the risk of pouchitis, a common inflammatory condition that occurs after colon removal surgery for ulcerative colitis, but the treatment may not be worth the cost depending on a patient’s likelihood of flare-ups.

NewsNew papers reveal how gut-brain interactions shape eating behaviors
Researchers found that stress from life circumstances can disrupt the brain-gut-microbiome balance. This disruption may alter mood, decision-making, and hunger signals — increasing the likelihood of craving and consuming high-calorie foods.

NewsPretreatment methods deploying microbes bring second-gen biofuels from oilcane closer to commercialization
In collaboration with other Bioenergy Research Centers (BRCs), researchers at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) are developing industrially feasible techniques for second-generation biofuel production from oilcane, an oil-rich variety of sugarcane, to help meet our growing societal demand for fuels.

NewsAntibody-making cells reveal new function in response to flu infection
A study has uncovered a new function of the immune cells that are known for making antibodies. Researchers determined that, in response to flu infection, a specialized set of B cells produce a key signaling molecule that the immune system needs to develop a robust, long-term response to fight off infections.

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.
-
NewsResearchers uncover relationship between gut fungi, human genetic variation and disease risk
A study uncovers evidence of the first ternary relationships between human genetic variation, variation in gut mycobiome, and risk of developing chronic disease.

NewsOne shot of RSV vaccine effective against hospitalization in older adults for two seasons
One shot of an RSV vaccine protects adults ages 60 or older from RSV-associated hospitalization and critical illness during two consecutive RSV seasons, according to a new study.

NewsUnder The Lens: Raquel Peixoto reveals how tourists armed with probiotics could save world’s coral reefs
A fascinating conversation between Applied Microbiology International President Professor Jack Gilbert and Professor Raquel Peixoto examines how understanding and leveraging coral microbiomes is leading to innovative probiotic solutions to boost coral resilience.

NewsCARB-X backs neonatal sepsis diagnostic platform by Quantamatrix
CARB-X has awarded QuantaMatrix Inc. US$2.85M to execute a workplan to develop its rapid diagnostic platform to detect sepsis, especially in vulnerable neonates. The test aims to deliver results within just 6 hours from very small blood samples of 1 to 2 milliliters.
