Rockefeller scientists reveal how a narrow-spectrum antibiotic selectively targets C. diff

Most antibiotics are double-edged swords. Besides killing the pathogen they are prescribed for, they also decimate beneficial bacteria and change the composition of the gut microbiome.

Study reveals how plants activate their immune system to prevent infections caused by rain

While rain is essential for the survival of plants, it also contains bacteria and other pathogens which can cause them harm. So how do plants protect themselves from this threat?

Transposons are a potential antibiotic resistance, a study reveals

According to biomedical engineers at Duke University, the physical mechanism that enables high doses of antibiotics to encourage the transmission of antibiotic resistance across bacteria is now identified.

Chemical component geosmin’s taste makes bacteria-eating worms at risk

Geosmin has a distinct smell that pervades the air after a summer rainstorm or fills your nose when gardening. It smells like moist dirt—earthy and somewhat comfortable.

Gut microbiota may play a role in resistance to blood pressure medicines

Almost half of the U.S. adult population has high blood pressure - or hypertension - and about 20% of these patients have treatment-resistant hypertension.

Researchers discover a unique technique to fight hospital-borne disease

A study team developed an early-stage therapy that sabotages the pump and restores antibiotic efficiency by disclosing the structure of a protein needed by bacteria to pump out antibiotics.

Researchers show how proteins form DNA-repair mechanism in living bacteria

Two recent research have shown a completely new perspective of how bacterial cells repair broken parts of their DNA (lesions).

Plant biologists determine molecular ‘blueprint’, showing how plants observe light

For survival, plants depend on their ability to detect light. Plants, unlike animals, do not have photoreceptors in their eyes to receive and transmit messages from visual inputs.

Researchers focus to create a new class of molecules for curing biofilm infections

Chronic skin wounds are a rising global issue among the elderly, individuals with severe burns, and people with underlying medical diseases such as diabetes.

Exceptional research recordings display RNA switching “on” and “off”

RNA switches (also known as riboswitches) control which genes are turned “on” and “off”, much like a light switch. Although this appears to be a straightforward process, biologists have been astonished by the inner workings of these switches for decades.

Northern olingo may be an important seed dispersion agent for unique epiphytic gymnosperm

For biologists performing fieldwork, sleeping in a car may be necessary.

Scientists discover how bacteria swim through complex fluids and environments

For years, science fiction authors have written about the idea of using microswimmers that could perform surgeries or deliver medicines to humans.

UC Riverside scientists aim to find how some fungi and bacteria manage to thrive post-wildfires

Scientists have found microbes living in the charred soil that wildfires leave behind. They don't know how some fungi and bacteria manage to thrive when everything else has died, but a new project aims to change that.

Study highlights the importance of membrane composition of targeted cells

Bacteria, fungi, and yeast are very good at excreting useful substances such as weak acids. One way in which they do this is through passive diffusion of molecules across the cell membrane. At the same time, cells need to prevent leakage of numerous small molecules.

Tuberculosis causes early epigenetic aging in cells, study finds

In the current study, scientists at Baylor College of Medicine identified that the cells of humans and animals that recovered from tuberculosis had prematurely aged up to 12 to 14 years.

Salmonella strains in birds do not harbor antimicrobial-resistance genes, study finds

Although many wild birds carry Salmonella, the strains of the bacteria they convey usually do not harbor antimicrobial-resistance genes, according to Penn State researchers, who led a team conducting a new, nationwide study.

New long-lived biological computers could potentially persist inside cells

Tiny biological computers made of DNA could revolutionize the way we diagnose and treat a slew of diseases, once the technology is fully fleshed out.

Study reveals novel mechanism used by infectious bacteria to survive stressful situations

A new study led by researchers at University of Utah Health details a novel mechanism that infectious bacteria use to quickly adjust to environmental stress. The discovery could help explain why certain types of common infections-;such as urinary tract and bloodstream infections like sepsis- are hard to get rid of.

New discovery likely to result in cancer vaccine development

According to research published in eLife, researchers have developed a pipeline for detecting, prioritizing, and testing potential tumor antigens for the rapid development of cancer vaccines.

Study shows how CRISPR RNAs help the immune system to identify and combat viruses

What tasks must be completed today, and which are the most vital? In their daily lives, people must continuously make priorities. Bacteria are no exception: while using CRISPR to battle viruses, they must prioritize as well. However, the method by which this priority is accomplished is unknown.
