Low-dose exposure to antibiotics can have major impacts on gut bacteria

An antibiotic commonly found at low concentrations in the environment can have major impacts on gut bacteria, report researchers at the University of Oregon.

Nanostructured surfaces can minimize bacterial adhesion

Staphylococcus aureus bacteria are one of the main causes of hospital-acquired infections. These pathogens are particularly problematic because they can form highly robust biofilms on both natural and artificial surfaces and are very difficult to remove.

CRISPR RNA-cutting enzyme programmed to destroy viruses in human cells

Many of the world's most common or deadly human pathogens are RNA-based viruses -- Ebola, Zika and flu, for example -- and most have no FDA-approved treatments.

Histone modifications play important role in 'zygotic genome activation'

Scientists at Tokyo Institute of Technology observed changes to the gene-regulating factors during zebrafish development and discovered that modifications to "histone H3", one of the proteins around which DNA is bound, play an important role in "zygotic genome activation" or transition of control of zebrafish embryonic development from maternal material to the zygote .

Collagen fiber length may be a key overlooked parameter used by normal cells to become invasive

Collagen is the most abundant protein in mammals, making up skin, bone, tendons and other soft tissues. Its fibrous nature helps cells to move throughout the body, but until now, it wasn't clear how the length of fibers influences how cells move in groups.

Study presents a new view on how mitochondrial dysfunction may contribute to aging

Disturbances in the function of mitochondrial DNA can accelerate the aging process in ways that are different than previously thought, according to a new Finnish study published in Nature Metabolism.

Scientists show how protein Ikaros orchestrates fine balance to control autoimmunity

The immune system relies on B cells and their ability to make antibodies against an extremely broad range of pathogens. This broad responsiveness bears some risk, as B cells can also turn against healthy tissue - a phenomenon called autoimmunity.

Salford scientists identify new drug candidate to starve and suffocate breast cancer stem cells

Scientists have identified a new drug candidate that is able starve and suffocate cancer stem cells, paving the way for new therapies to treat breast cancer patients.

Scientists study how immune cells sense and respond to their environment to fight diseases

Scientists at the University of Dundee have carried out one of the most comprehensive studies into how immune cells sense and respond to their environment to fight infection and destroy tumors.

Researchers determine how the colon prioritizes gas detox over energy use

Onions, cabbage, garlic. While nutritious, eating these foods can lead to an embarrassing side effect: smelly flatulence. More than just smelly, hydrogen sulfide, the chemical compound responsible for the rotten-egg aroma, is deadly if inhaled at doses of more than 700 parts per million.

Scientists use organoid technology to achieve stable long-term cultures of mouse urothelial cells

Investigation of biological mechanisms in urothelial tissue -one of the three types of tissue that make up the urinary system- has always been very limited due to the lack of technologies that allow working with stable and long-term populations of the cells that compose it.

Researchers develop 3D tissue models of brain tumors in a brain-mimicking microenvironment

A team of Tufts University-led researchers has developed three-dimensional human tissue culture models of pediatric and adult brain cancers in a brain-mimicking microenvironment, a significant advancement for the study of brain tumor biology and pharmacological response.

Exploiting the weak spot in pathogenic bacteria to develop new antibiotics

Antibiotics are still the most important weapon for combatting bacterial infections. But medical science is running out of "ammunition" because of more and more frequently occurring resistances.

Viagra enables rapid and efficient hematopoietic stem cell mobilization in mice

The combination of two clinically approved drugs--Viagra and Plerixafor--rapidly and efficiently mobilizes blood stem cells from the bone marrow into the bloodstream in mice, researchers report October 10th in the journal Stem Cell Reports.

Rapid progress in brain organoid research prompts ethical debate

A new paper has tried to address the ethical debate surrounding human organoids by evaluating the potential risks of creating “humanized” animals

Findings shed light on molecular reasons for early miscarriage

Researchers at Karolinska Institutet in Sweden have uncovered a chromosome-wide mechanism that keeps the gene expression of sex chromosomes in balance in our cells.

Chemical-sensing cells in the gums protect the mouth from infections

Newly discovered chemical-sensing cells in the gums protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth, report researchers from the Monell Chemical Senses Center in an animal study published this week in Nature Communications.

Certain fungi increase pancreatic cancer risk, study finds

Certain fungi move from the gut to the pancreas, expand their population more than a thousand-fold, and encourage pancreatic cancer growth, a new study finds.

Researchers observe the effects of two proteins responsible for metastasis

The research by Assoc. Prof. Nurhan özlü of Koç University Department of Molecular Biology and Genetics and her team recently published in Molecular & Cellular Proteomics has observed the effects of two proteins in the transition from the epithelial to the mesenchymal cell type, the latter of which has mobility.

Findings could open up new research avenues into how heme tolerance occurs in humans

Most people have some idea of how important iron is to their health, but Iqbal Hamza, professor in Animal and Avian Sciences, has made his seventeen-year career at the University of Maryland all about the study of iron and heme trafficking and regulation in the body.
