Deciphering the mechanisms used by a fungus to increase iron acquisition

The University of Cordoba discovered how the entomopathogenic fungus Metarhiziumbrunneum increases iron acquisition in melon and cucumber.

Study evaluates the risk posed by the fungus Bd to amphibians across the continent of Africa

Mass fungus infections that drive populations worldwide to near-collapse don't just occur in science fiction. Chytridiomycosis, the worst vertebrate disease in recorded history, has already wiped out hundreds of species of amphibians around the world. Due to a large part to this fungal disease, 41% of amphibians are currently threatened with extinction. Only species living in Africa seemed to have been relatively spared from the scourge of chytridiomycosis – at least so far.

Study evaluates the use of DNA metabarcoding to identify fish eggs

A new study published in PeerJ Life & Environment and featured in the International Association for Biological Oceanography Hub evaluates the use of DNA metabarcoding to identify fish eggs.

Gene that regulates cadmium distribution between leaf and grain in rice

Due to its accumulation in crops, specifically rice, cadmium (Cd), a hazardous heavy metal contaminant of cultivated land, poses a threat to human health. Thus, it is vital to develop methods to prevent Cd from accumulating in rice grains.

High correlation between the product of a gene in the majority of cancers

The product of a gene expressed in most cancers, including the most prevalent type of head and neck cancer, has been linked to elevated levels of white blood cells that produce antibodies inside tumors, according to researchers at the University of California San Diego School of Medicine and UC San Diego Moores Cancer Center.

Rice biologists embark on a three-year project to create genetically encoded antibiotics

Synthetic biologists at Rice University are embarking on a three-year project to create "genetically encoded antibiotics," strands of RNA that bacteria will readily copy and share that will selectively kill only disease-causing, pathogenic bacteria.

Understanding the factors that impact CRISPRa efficiency

Investigators, from the Wellcome Sanger Institute and partners, utilized human stem cells and neurons to explore what attributes impact how well CRISPR activation works for different sets of genes.

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.

Bile salt hydrolase cocktails may offer a new approach to inhibit C. diff colonization

Not all probiotics are created equal. In a new study, researchers found that certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut's microbial environment.

SMART researchers develop the world's first microneedle-based drug delivery technique for plants

Researchers from the Disruptive & Sustainable Technologies for Agricultural Precision (DiSTAP) Interdisciplinary Research Group (IRG) of Singapore-MIT Alliance for Research and Technology (SMART), MIT’s research enterprise in Singapore, and their collaborators from Temasek Life Sciences Laboratory (TLL) and Massachusetts Institute of Technology (MIT), have developed the first-ever microneedle-based drug delivery technique for plants.

Effective backup mechanism ensures efficient antimicrobial responses in humans

In the human body, virus particles are identified by pattern recognition receptors (PRRs) either within or on the cell surface. When a receptor is activated, a signaling cascade is initiated, which results in the production and release of signaling molecules like interferons and cytokines.

Significance of astrocyte–neuron interactions in fine-tuning brain function

Humans learn to handle a variety of skilled movements throughout their lives, from driving a car to swinging a tennis racket. Neurons are not the only ones who implement this learning, but a new study from The Picower Institute for Learning and Memory at MIT shows that astrocytes play an important role as well.

Novel technology easily detects active Mycobacterium tuberculosis infection antibodies

A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.

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.

Study investigates schizophrenia risk across African ancestry

Researchers have identified two previously unknown genes linked to schizophrenia and newly implicated a third gene as carrying risk for both schizophrenia and autism. Led by the Icahn School of Medicine at Mount Sinai, the multi-center study further demonstrated that the schizophrenia risk conferred by these rare damaging variants is conserved across ethnicities. The study may also point to new therapeutics.

Bacteriophages might hold the key to fighting antibiotic resistance

As conventional antibiotics continue to lose effectiveness against evolving pathogens, scientists are keen to employ the bacteria-killing techniques perfected by bacteriophages, the viruses that infect bacteria.

Neural-network-based image recognition models for examining SCC defects

Scientists from Tokyo Metropolitan University have used machine learning to automate the identification of defects in sister chromatid cohesion. They trained a convolutional neural network (CNN) with microscopy images of individual stained chromosomes, identified by researchers as having or not having cohesion defects. After training, it was able to successfully classify 73.1% of new images. Automation promises better statistics, and more insight into the wide range of disorders which cause cohesion defects.

New class of oral drugs inhibits a diverse range of SARS-CoV-2 strains

The constant evolution of new COVID-19 variants makes it critical for clinicians to have multiple therapies in their arsenal for treating drug-resistant infections. Researchers have now discovered that a new class of oral drugs that acts directly on human cells can inhibit a diverse range of pathogenic SARS-CoV-2 strains.

Study investigates the complex evolutionary history of jewel beetles' vision

Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants.
