Molecular responses of Pseudomonas aeruginosa to hydroquinine

Researchers investigating the effects of an organic compound on drug-resistant bacteria found how it can impede and destroy a germ that causes significant illness or even death in some situations.

Plant root reprogramming via synthetic genetic circuits

An essential stage in genetically modifying plants to create better bioenergy crops is gene activity control. The results of this research led to the creation of artificial genes that could be coupled to produce certain patterns of gene expression in plants.

New drug to tackle complex cases of UTI

A new drug combination has been shown to be more successful, especially against persistent, drug-resistant infections, according to an international study conducted by a Rutgers Researcher comparing new and older therapies for complex urinary tract infections.

Bacteria do engage in photosynthesis, research suggests

Knowing whether or not marine microbes engage in photosynthesis -; the use of sunlight to turn carbon dioxide and water into energy -; could help scientists to learn if ocean bacteria play a role in the global carbon cycle.

Organic chemical compounds impact the abundances, compositions of reef microorganisms differently

Stumbling upon a new source of underwater caffeine was just an added bonus of a new study examining the impact of chemical compounds that corals release into the seawater.

All normal human tissues express remnants of widespread retrovirus

Ancient viral remnants in the human genome are active in both healthy and diseased tissues, restricting their applicability as disease indicators, according to a study published on October 18th, 2022, in the open access journal PLOS Biology by Aidan Burn at Tufts University in Boston, USA and colleagues.

Dual threat may lead cyanobacteria to take in more carbon

The types of ocean bacteria known to absorb carbon dioxide from the air require more energy – in the form of carbon – and other resources when they're simultaneously infected by viruses and face attack from nearby predators, new research has found.

Role of hormones and their receptors in the plant stress response

Crops are frequently subjected to unfavorable growing conditions. Disease, severe temperatures, and saline soils, for example, cause plants to utilize energy to adapt to stress rather than for development.

Bacterial warfare in the gut can have collateral beneficial effects

Nearly ten years ago, a graduate student at UO Jennifer Hampton Hill stumbled upon something fortunate: a peptide produced by gut bacteria that prompted the division of cells that make insulin.

Molecular insights into the photosynthesis process

The most essential foundation of life on Earth is photosynthesis. Plants and single-celled algae use sunlight’s energy to turn it into sugar and biomass.

Brain-resident and recruited macrophages exhibit diverging responses

Prof. Kiavash Movahedi (VUB, VIB) headed a group that outlined how the immune system responds to infections entering the brain. The results offer new information on host-pathogen interactions as well as the long-term effects of brain infections.

Gut microbiome’s influence on how lifestyle affects dementia risk

A recent Baycrest study points to the possibility that the gut microbiome influences how nutrition and exercise impact brain health and dementia risk. Physicians and researchers could be able to improve dementia prevention efforts with the use of this knowledge.

New technique identifies tumor-associated microbes

Researchers from Rutgers Cancer Institute of New Jersey and RWJBarnabas Health investigated the microbiome of pancreatic tumors and discovered certain microbes linked to inflammation and poor survival.

Discovery and characterization of a new antifungal compound

Antimicrobial resistance has prompted scientists to search for novel compounds everywhere. A multinational group of European scientists reports the discovery of solanimycin, a novel antifungal antibiotic.

The role of bacteria in preserving marine phytoplankton

Heterotrophic bacteria, according to a study from the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS), may be to blame for the phytoplankton’s continued survival.

Spores integrate environmental signals over time

When exposed to starvation and stress, certain bacteria enter a dormant state in which life functions cease. These cells, known as spores, can resist punishing extremes of heat, pressure, and even the extreme conditions of outer space by entering a profound hibernation.

Microbiome manipulation to prevent and cure diseases

Tagbo Niepa, assistant professor of chemical engineering at the University of Pittsburgh, is inspired by this possibility in his research. His work on using the microbiome to enhance human health was recognized with a $2 million New Innovator Award from the National Institutes of Health, which funds “exceptionally creative scientists proposing high-risk, high-impact research.”

Marine phytoplankton and heterotrophic bacteria may have an inseparable close relationship

A phytoplankton almost as old as Earth -; about 3 billion years compared to the planet's 4.5 billion years -; still holds secrets, including how it can survive starvation in the most nutrient-deficient oceans.

Newly isolated Bacteroides likely to be present in mammals beyond mice

In the DFG-funded Collaborative Research Center (CRC) 1182 “Origin and Function of Metaorganisms,” scientists from Kiel University and the Max Planck Institute for Evolutionary Biology in Plön (MPI-EB) are investigating the evolutionary history and function of Bacteroides.
