Scientists unravel iron-based memory mechanism in bacteria

Scientists have discovered that bacteria can create something like memories about when to form strategies that can cause dangerous infections in people, such as resistance to antibiotics and bacterial swarms when millions of bacteria come together on a single surface.

Fresh risks in ready-to-eat produce: Study reveals how common pathogens lurk in our salads

This research paper delves into the risks of contamination in ready-to-eat fruits and vegetables by enteric pathogens like E. coli, Salmonella, and Listeria, which can lead to foodborne illnesses. It also explores the contamination sources and plant-pathogen interactions, emphasizing the importance of improved safety measures in the food supply chain.

How one gene shakes up our understanding of male infertility

The study investigates the role of the ACTL7B gene in sperm formation using genetically modified mice and finds that deficiencies in this gene lead to failed spermatogenesis and structural sperm abnormalities. Given the gene's similarity in humans, the findings suggest ACTL7B could serve as a potential biomarker for male infertility.

Viruses exploit ability to sense the environment to maximize their infective yield

New UMBC-led research in Frontiers in Microbiology suggests that viruses are using information from their environment to "decide" when to sit tight inside their hosts and when to multiply and burst out, killing the host cell. The work has implications for antiviral drug development.

Stopping a pervasive bacterium that makes millions sick each year

As we head outdoors this summer, scientists are working to clip the long, flexible appendages that enable the common bacterium Campylobacter jejuni to make its way from undercooked poultry and natural waterways into our intestinal tract where it makes millions of us sick each year.

Scientists develop nature-inspired steerable catheter for brain surgery

A team of engineers and physicians has developed a steerable catheter that for the first time will give neurosurgeons the ability to steer the device in any direction they want while navigating the brain's arteries and blood vessels.

Study describes IgG antibodies in Crohn's disease specific for human bacterial flagellins

Last year, Charles O. Elson, M.D., demonstrated a potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease. He used a mouse model that included immune-reactive T cells from patients with Crohn's disease in a flagellin peptide-specific immunotherapy.

Study shows how self-swimming microbes survive in harsher environments

Many bacteria swim towards nutrients by rotating the helix-shaped flagella attached to their bodies. As they move, the cells can either 'run' in a straight line, or 'tumble' by varying the rotational directions of their flagella, causing their paths to randomly change course.

Newly discovered protein regulates molecular motors in response to light

Single-celled algae and animal sperm cells are widely separated in evolution but both swim in the same way, by waving their protruding hairs, called cilia or flagella. Motion is driven by molecular motors, complex assemblies of proteins that exert a force when changing shape.

Single-dose universal vaccine could protect against leptospirosis bacteria

Scientists have designed a single-dose universal vaccine that could protect against the many forms of leptospirosis bacteria, according to a study published today in eLife.

Glycylation essential to keep sperm swimming in a straight line, shows study

One essential component of each eukaryotic cell is the cytoskeleton. Microtubules, tiny tubes consisting of a protein called tubulin, are part of this skeleton of cells.

Mutual bacterial-fungal relationship allows microbes to travel in exchange for thiamine

Tiny organisms head out on the highway, looking for adventure like they've ridden straight out of the 1960s rock hit, "Born to Be Wild." Researchers from Japan have discovered that while perhaps not as thrill-seeking, bacteria do indeed travel on fungal highways and pay a toll in return.
