Salk researchers discover how cells remember their identity

Cancer is often the result of DNA mutations or problems with how cells divide, which can lead to cells "forgetting" what type of cell they are or how to function properly.

Small protein has a great influence on bacterial gene regulation

Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of more than 250 bacterial genes.

Fate-seq technique shows structural differences between COVID-19 and SARS viruses

Scientists have discovered certain segments of the genetic codes of the SARS and COVID-19 viruses that may support the lifecycle of the viruses.

Review reveals exceptions to the purported rules of sex chromosome evolution theory

For nearly a century, biologists have modeled the evolution of sex chromosomes--the genetic instructions that primarily determine whether an individual will develop into a male or female (or a certain mating type)--resulting in an impressive theoretical framework.

Study identifies gene responsible for eye loss in cavefish

Mexican cavefish spend their entire lives in the dark. With no need for vision, many of them lost functional eyes.

Scientists decode ancient DNA extracted from Dead Sea Scrolls

An interdisciplinary team from Tel Aviv University, led by Prof. Oded Rechavi of TAU's George S. Wise Faculty of Life Sciences, Prof. Noam Mizrahi of TAU's Department of Biblical Studies, in collaboration with Prof. Mattias Jakobsson of Uppsala University in Sweden, the Israel Antiquities Authority and Prof. Christopher E. Mason of Weill Cornell Medicine, has successfully decoded ancient DNA extracted from the animal skins on which the Dead Sea Scrolls were written.

Study sheds light on the complexity of HIV-1 nuclear entry

The process of cells being infected by HIV-1 strains is widely known to undergo many stages.

New insights into recombination of sex chromosomes during meiosis

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life.

gnomAD Consortium releases first set of discoveries on human genetic variation

For the last eight years, the Genome Aggregation Database Consortium (and its predecessor, the Exome Aggregation Consortium, or ExAC), has been working with geneticists around the world to compile and study more than 125,000 exomes and 15,000 whole genomes from populations around the world.

ADHD-associated genetic variants have reduced progressively in human lineage

According to a study published in the Scientific Reports journal, the frequency of genetic variants linked to attention-deficit/hyperactivity disorder (ADHD) has reduced progressively in the evolutionary human lineage from the Palaeolithic to the present day.

Study provides new strategies for treating different types of cancer

An RNA molecule involved in preventing the formation of tumors can modify its structure and thus regulate the production of proteins in the cell.

New CRISPR-Cas9 based method for directed protein evolution

"Directed evolution" is the process by which scientists produce tailor-made proteins for cell biology, physiology and biomedicine in the laboratory.

Study shows how ocean virus captures the metabolism of carbon-storing bacteria

Below the surface of the ocean, a virus is stealing the metabolism of the most abundant organism present on Earth. That might be attractive to those who breathe above the ocean’s surface.

Using CRISPR/Cas molecular scissors to recombine entire chromosomes

The CRISPR/Cas molecular scissors work like a fine surgical instrument and can be used to modify genetic information in plants.

New sequencing method helps map the spatial arrangement of DNA

A sequencing technique helps to map the spatial arrangement of DNA in the cell nucleus, revealing which regions of the genome are at greater risk of mutation.
