Not so identical: Genetic difference in twins can begin very early on in the embryo
When a mutation happens in the first few weeks of embryonic development, it would be expected to be widespread both in an individual's cells and in those of their offspring.
Powerful new gene editing tool adapted from CRISPR-Cas9 can make larger DNA repairs
The new capability to delete or replace long stretches of DNA could help researchers better understand disease conditions and ageing.

New study reveals why different people experience varying intensity of COVID-19 symptoms
As per the study, the expression of about eight genes such as the ones responsible for hypoxia, uncontrolled inflammation or cytokine storm, oxidative stress and vitamin K biosynthesis, increased with age, suggesting the higher susceptibility of the elderly to the SARS-CoV-2 virus
Neanderthal genes passed down makes some people more prone to COVID-19 infection, a new study proposes
The Neanderthal gene was found highest in Bangladeshi ancestry, with 63 percent of its population carrying at least one copy of the risk variant.
