Engineering a phage's DNA by introducing modified CRISPR-Cas machinery genes

Bacteriophages (or phages) are viruses that infect bacteria. They are the most abundant biological entity, and they can be found wherever bacteria live. To propagate themselves, phages inject their DNA into their bacterial hosts.

New models provide better understanding of how life originated

The first signs of life emerged on Earth in the form of microbes about four billion years ago. While scientists are still determining exactly when and how these microbes appeared, it's clear that the emergence of life is intricately intertwined with the chemical and physical characteristics of early Earth.

Two-step screening of aroma compounds reveals a novel and effective modulator of dendritic cells

Dendritic cells (DCs) are important players of the immune system with important functions such as the identification of infectious pathogens, production of cytokines (chemical signalers of the immune system), presentation of antigens to activate T-cells, and more.

New route to understanding the origins of life

A team of scientists from France and Austria has discovered a new abiotic pathway for the formation of peptide chains from amino acids - a key chemical step in the origin of life.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.

Tissue inflammation altered by “natural killer” immune cells

The discovery of a previously unknown role of “natural killer” (NK) immune cells by Melbourne researchers has increased the current understanding of how the immune system is controlled to prevent disease.

Identifying the molecular switch that regulates autophagy in plants

Autophagy, commonly known as “self-eating,” is a cellular quality control mechanism that relieves the cell of protein aggregates and damaged organelles. This system is inert under ordinary conditions and is only activated in the presence of persistent cellular stress.

Research reveals gene expression changes in two brain regions of individuals with cocaine use disorder

Individuals with cocaine use disorder exhibit gene expression changes in two brain regions: the nucleus accumbens, a region associated with reward, and the caudate nucleus, a region mediating habit formation, according to research conducted at the Icahn School of Medicine at Mount Sinai and published February 10 in Science Advances.

Measurement of plasma D-dimer levels can be useful when diagnosing periprosthetic joint infection

Measurement of plasma D-dimer levels – a test more commonly used to detect blood-clotting disorders – can provide useful information when making the difficult diagnosis of periprosthetic joint infection (PJI), reports a study in The Journal of Bone & Joint Surgery.

Pancreatic islet microexons play key role in islet function and glucose homeostasis

When cells copy DNA to produce RNA transcripts, they include only some chunks of genetic material known as exons and throw out the rest.

The correlation between Type 2 diabetes and human microRNAs

Although it has long been believed that microRNA (miRNA) molecules in pancreatic islets play significant roles in Type 2 diabetes, no specific miRNAs have been definitively linked to the disease in humans.
