Fastest-evolved regions of the human genome diverged rapidly after split from chimpanzee ancestor

A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.

RNA-targeting strategy to repair the genetic cause of ALS and dementia

Researchers at UF Scripps Biomedical Research have created a potential treatment for a major factor in the development of ALS and dementia that functions by removing disease-causing RNA segments.

New effort to generate high quality reference genomes for 1,000 known species of euglenoids

The Euglena International Network (EIN) (https://euglenanetwork.org/), founded in 2020, is a global consortium of hundreds of scientists around the world with the collective goal of supporting euglenoid science through collaborative and integrative omics between academics and industry.

Highlighting the potential of new techniques to study mental disorders

Researchers investigating the fundamental brain mechanics of autism spectrum disorder have discovered that a gene mutation known to be connected with the illness causes considerably more overstimulation of brain cells than in neuronal cells without the mutation.

Expanding the CRISPR-based toolbox for extensive genome engineering

Researchers from North Carolina State University describe a variety of CRISPR-Cas systems-based molecular tools to rewrite, rather than just edit, significant portions of an organism’s DNA.

The influence of genes and small molecules on personal disease risk

Each individual has a unique chemical fingerprint. Small molecules in the blood, like fats or sugars, have a significant impact on how the human body responds to stress, which diseases people are predisposed to, and how serious an illness will be.

Molecular motion of “undruggable” proteins reveals drug-binding sites

“Undruggable” proteins, whose structures and roles in disease are known but who appear unable to be targeted by drugs that will bind to them, present some of the hardest problems in disease treatment.

Chemically attenuated live DNA virus vaccine prevents viral infection

Rutgers researchers have devised a new way to prevent viral infections: a live-attenuated, replication-defective DNA virus vaccine that utilizes the substance centanamycin to create an altered virus for vaccine development.

3D “mini eyes” provide insight into genetically induced blindness

The development of “mini eyes” by researchers at the UCL Great Ormond Street Institute of Child Health (UCL GOS ICH) has made it possible to study and comprehend the onset of blindness in the rare genetic disease known as Usher syndrome more.

Genetics and extensive schooling likely cause nearsightedness in children

Researchers have discovered five genetic variations that, the longer a person attends school, increase their risk of developing nearsightedness. These results were published on November 17th, 2022 in the open-access journal PLOS Genetics by a team at Cardiff University in the United Kingdom, led by Jeremy Guggenheim.

Adaptation to climate change in plants aided by epigenetic memories

Animals are able to quickly adapt to changing environmental conditions and survive. There is growing evidence that plants can, too.

Waste disposal mechanism of mitochondria to remove mtDNA mutations

University of Cologne researchers have uncovered the mechanism by which cells can get rid of mutated mitochondrial DNA (mtDNA)—the heart of each of our cells, the mitochondria.

Applying “programmable molecular scissors” to combat COVID-19 infection

As an approach that could be used to create a new class of antiviral drugs, synthetic biology was used by Cambridge scientists to artificially create enzymes programmed to attack the genetic code of SARS-CoV-2 and eliminate the virus.

Enzymes hold the answer to understanding how DNA mutates

According to recent research from the University of Surrey, enzymes, which are essential for regulating how cells replicate in the human body, could be the very component that encourages DNA to spontaneously mutate, leading to potentially permanent genetic errors.

The genetic mechanisms that induce protein decline in modern maize

The wild ancestor of maize, teosinte, contains three times as much seed protein as the majority of cultivars of maize today. The mechanisms causing the declining seed protein content in maize hybrids and inbred lines were identified by researchers at the Chinese Academy of Sciences Headquarters.

A gene’s function in embryonic development

An international study led by the medical school at the University of Bonn has discovered a gene that is crucial to the growth of the human embryo. Abnormalities of different organ systems may occur if it is changed.
