Science Alert reports:
People who eat a lot of industrially processed junk food are more likely to exhibit a change in their chromosomes linked to aging, according to research presented Tuesday at an online medical conference. Three or more servings of so-called “ultra-processed food” per day doubled the odds that strands of DNA and proteins called telomeres, found on the end of…

Sharon Moalem interview: Why women are genetically stronger than men
We know that women live longer and are less susceptible to certain diseases than men. That may be down to the benefits of having two X chromosomes Source: https://www.newscientist.com/article/mg24732930-900-sharon-moalem-interview-why-women-are-genetically-stronger-than-men/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
CRISPR Gene Editing In Human Embryos Wreaks Chromosomal Mayhem
A suite of experiments that use the gene-editing tool CRISPR-Cas9 to modify human embryos have revealed how the process can make large, unwanted changes to the genome at or near the target site. Nature reports: The first preprint was posted online on June 5 by developmental biologist Kathy Niakan of the Francis Crick Institute in London and her colleagues. In that…
CRISPR Now Cuts and Splices Whole Chromosomes
Researchers report they’ve adapted CRISPR and combined it with other tools to cut and splice large genome fragments with ease. The study, conducted by researchers at the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, U.K., has been published in this week’s issue of Science. Science Magazine reports: The tried and true tools of genetic engineering simply can’t handle…

Men who have children later in life may prime their kids for longevity
Older dads may change the chromosomes in their sperm so that their children will be able to live longer lives – a phenomenon similar to Lamarckian evolution Source: https://www.newscientist.com/article/mg24232263-000-men-who-have-children-later-in-life-may-prime-their-kids-for-longevity/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Does a year in space make you older or younger?
