Resistance genes in human gut influenced by national trends in antibiotic consumption

According to a new study performed at the Earlham Institute and Quadram Institute in Norwich, the community of microbes living in and on human bodies might be serving as a reservoir for antibiotic resistance.

TurboID-based proximity labeling in meiotic cells of Arabidopsis thaliana

During meiosis, reshuffling of genetic information between homologous chromosomes through meiotic recombination creates variable gametes and hence genetic variation in offsprings.

Analyzing the antimicrobial resistance profile of the main agent of urinary tract infections

The human intestine is an environment inhabited by many bacteria and other microorganisms collectively known as the gut microbiome, gut microbiota or intestinal flora. In most people, it contributes to wellness. A healthy gut indicates a stronger immune system, improved metabolism, and a healthy brain and heart, among other functions.

Monitoring the development and maturation of cardiomyocytes using tissue-embedded devices

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue.

CRISPR/Cas method could help save rice crops threatened by climate change

A review of gene editing techniques suggests that the CRISPR/Cas (clustered regularly interspaced short palindromic repeats/Cas) method could be a possible 'savior' for rice crops threatened by climate change and high food demand.

Study shows why a specific gene mutation has opposite effects on mice and human cancers

A small but significant metabolic difference between human and mouse lung tumor cells, has been discovered by Weill Cornell Medicine researchers, explaining a discrepancy in previous study results, and pointing toward new strategies for developing cancer treatments.

High diversity in T-cell receptor genes explains diverse response to infections

Researchers from Karolinska Institutet have demonstrated that the genes that encode the T cell receptors change significantly between individuals and communities, which could help explain why people react differently to certain diseases.

Researchers reveal link immune system genetics and a person's ability to resist new COVID-19 variants

An international team including researchers from the HSE University Faculty of Biology and Biotechnology has found a link between certain genetic features of the immune system and one's ability to effectively resist new waves of COVID-19.

Understanding how tiny organisms thrive after wildfires

UC Riverside researchers have identified tiny organisms that not only survive but thrive during the first year after a wildfire. The findings could help bring land back to life after fires that are increasing in both size and severity.

Revealing the propagation of singlet oxygen along double stranded DNA

Nucleic acid-targeting photodynamic therapy (PDT) is an innovative type of targeted therapy that is currently being studied. This treatment is based on photosensitizers, which are drugs that attach to specific regions in a cell’s DNA.

Potential to rectify various disease-causing mutations enhanced by CRISPR-based enzymes

Designing genome editing strategies for each patient’s mutation would be impractical and expensive because many genetic diseases are induced by diverse mutations spread across an entire gene.

Detecting the extent of natural selection over time

Institut Pasteur, Université Paris Cité, the CNRS, and the Collège de France researchers have employed paleogenomics to trace 10,000 years of human immune system evolution. They examined the genomes of over 2,800 individuals who lived in Europe over the past 10 millennia.

Grasping how a biological pathway causes stem cells to regenerate or die

According to a recent study conducted by Cedars-Sinai and the University of California, San Francisco (UCSF), altering a cellular process can cause stem cells, which are the cells that give rise to all other types of body cells, to either die or regenerate.

Key genes driving cleft lip and palate identified

A research group headed by the University of Iowa recognized three genes that, when deleted, produce cleft lip or palate, a facial abnormality that affects around one in every 1,600 babies in the United States, according to the US Centers for Disease Control and Prevention.

The continued functioning of circadian clock of cells even after starvation

According to a study that was just published in eLife, cells that have a functioning molecular clock are better able to adapt to changes in glucose supply and can recover from long-term starvation more quickly.

Novel blood biomarker predicts a favorable response to CART cell therapy

A MedUni Vienna research group identified a particularly potent biomarker for clinical response to CAR-T cell therapy, establishing the conditions for the most effective use of this innovative therapy for lymphoma treatment.

Three-year interval appropriate between screening for colorectal cancer

Three years after the first negative multi-target stool DNA test, according to a scientific investigation into the best time to screen for colorectal cancer using non-invasive methods for detecting the disease’s targets in the stool, there were no colorectal malignancies discovered.

Bats use distinct laryngeal structures to generate echolocation and social calls

Bats use distinct structures in the larynx to produce high-frequency echolocation calls and lower-frequency social calls, according to a study by Coen Elemans at the University of Southern Denmark and colleagues, publishing November 29th in the open access journal PLOS Biology.
