Antibiotic resistance is transferring from humans to animals

Resistance to antibiotics could be moving from humans to animals, research by a Clemson University professor has shown. The research details results that demonstrate reverse zoonosis, a process by which humans infect other species of animal with diseases.

Concerns over GM mosquitoes released in Brazil

A field experiment that released genetically modified mosquitoes in Brazil to control natural populations of the insect may have had unintended consequences.

Altered microbiome in fruit flies can drive evolutionary change

The expression "you are what you eat" has taken on new meaning. In an experiment in fruit flies, or Drosophila melanogaster, researchers at the University of Pennsylvania have found that adding different species of microbes to the flies' food caused populations to diverge genetically, racking up significant genomic changes in just five generations.

UT Southwestern researchers identify novel mechanism that regulates fat formation

In work suggesting new therapeutic targets to fight obesity, UT Southwestern researchers have identified a novel mechanism that regulates the creation of fat in mammals.

Cancer cells survive chemotherapy by eating their neighboring tumor cells

Researchers from the Tulane University School of Medicine have discovered that some cancer cells survive chemotherapy by eating their neighboring tumor cells.

Pros and cons of gene editing technology

CRISPR technology has greatly facilitated gene editing. Associate Professor Thorsten Müller from Ruhr-Universität Bochum and Dr. Hassan Bukhari from Harvard Medical School discuss its pros and cons in a review article in the journal "Trends in Cell Biology" from 12 September 2019.

Mutant live attenuated Ebola virus elicits protective immunity in monkeys

Inoculation with an Ebola virus that has mutations in a protein called VP35 does not cause disease and elicits protection in monkeys, researchers show September 17 in the journal Cell Reports.

Study finds dietary fiber components that encourage growth of beneficial gut microbes

Humans choose food based on the way it looks, smells, and tastes. But the microbes in our guts use a different classification system--one that is based on the molecular components that make up different fibers.

Combination therapies can shrink lung tumors in mice and human cancer cells

Combining a new class of drug with two other compounds can significantly shrink lung tumors in mice and human cancer cells, finds a new study led by the Francis Crick Institute and The Institute of Cancer Research, London.

Bone marrow-derived cells also travel to the womb to help pregnancy

Bone marrow-derived cells play a role in changes to the mouse uterus before and during pregnancy, enabling implantation of the embryo and reducing pregnancy loss, according to research published September 12 in the open-access journal PLOS Biology.

Mutated ciliary genes tied to heart valve birth defect

The heart pumps blood throughout the body to provide the needed oxygen and nutrients. In the heart, blood flows to get oxygen from the lungs to deliver to the cells. Some of the most important structures in the heart are the valves, because they prevent the backflow of blood, avoiding the mixture of oxygenated blood with the ones that still need to be oxygenated.

New method developed to address failures in promising anti-cancer drug

Biomedical engineers at Duke University have developed a method to address failures in a promising anti-cancer drug, bringing together tools from genome engineering, protein engineering and biomaterials science to improve the efficacy, accuracy and longevity of certain cancer therapies.

Cure for Rett Syndrome a step closer as scientists successfully reactivate 'back-up’ genes

A team headed by Vincent Pasque at his Lab at KU Leuven alongside researchers from the Jean-Christophe Marine lab and the Edith Heard lab have made a significant step towards developing a treatment for Rett syndrome and other X chromosome linked disorders.

PSA testing can help detect prostate cancer in men with BRCA2 gene fault

Men with the BRCA2 gene fault have an increased risk of prostate cancer and could benefit from PSA (prostate specific antigen) testing to help detect the disease earlier, according to researchers funded by Cancer Research UK.

Stopping cold viruses dead by blocking replication

The common cold virus (and its more deadly cousins, the viruses that cause polio and acute flaccid myelitis) may just have met its nemesis. In a recent study published in the journal Nature Microbiology on September 16, 2019, scientists reported a potentially successful new approach to stop cold viruses from replicating inside human cells – by blocking the formation of a protein that is vital to this process.
