New computer program can read any genome sequence and decipher its genetic code

Yekaterina "Kate" Shulgina was a first year student in the Graduate School of Arts and Sciences, looking for a short computational biology project so she could check the requirement off her program in systems biology. She wondered how genetic code, once thought to be universal, could evolve and change.

Improper Z-RNA recognition contributes to pathogenesis of Aicardi-Goutières syndrome

Like DNA, RNA molecules contain information through unique combinations of four different nucleotides. However, through a molecular process called RNA editing, chemical changes can be made to adenosine nucleotides that convert them to a nucleotide called inosine by enzymes known as adenosine deaminases (ADARs).

Scientists develop an extremely potent siRNA with broad activity against SARS-CoVs

Researchers in Germany have developed a promising approach to suppressing the viral replication of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Research points to new opportunities to prevent treatment resistance in fragile X syndrome

Mark Bear, Picower Professor of Neuroscience at MIT, recalls the "eureka moment" 20 years ago when he realized that a severe developmental brain disorder -;fragile X syndrome-;might be treated with drugs that inhibit a neurotransmitter receptor called mGluR5.

Researchers describe a novel role for hnRNP E1 protein in binding DNA in the nucleus

Cancer is a devastating disease and is the second leading cause of death in the U.S. One of the hallmarks of cancer is genomic instability, or the tendency to accumulate mutations and damage to the DNA that leads to genome alterations during cell division.
