Squid (stock image).Credit: © Ramsey / Adobe Stock Revealing yet another super-power in the skillful squid, scientists have discovered that squid massively edit their own genetic instructions not only within the nucleus of their neurons, but also within the axon — the long, slender neural projections that transmit electrical impulses to other neurons. This is the […]Read More New genetic editing powers discovered in squid
Existing genetic variation in natural populations of Mediterranean mussels allows them to adapt to declining pH levels in seawater caused by carbon emissions. A new study by biologists from the University of Chicago shows that mussels raised in a low pH experimental environment grew smaller shells than those grown at normal pH levels, but the […]Read More Genetic variation gives mussels a chance to adapt to climate change
A comprehensive map of genes necessary for cancer survival is one step closer, following the validation of the two largest CRISPR-Cas9 genetic screens in 725 cancer models, across 25 different cancer types. Scientists at the Wellcome Sanger Institute and the Broad Institute of MIT and Harvard compared the consistency of the two datasets, independently verifying […]Read More CRISPR-Cas9 datasets analysis leads to largest genetic screen resource for cancer research
Getting a good night’s sleep could be beneficial for long-term health. A pioneering new study led by Dr. Lu Qi, director of the Tulane University Obesity Research Center, found that even if people had a high genetic risk of heart disease or stroke, healthy sleep patterns could help offset that risk. The study is published […]Read More Can good sleep patterns offset genetic susceptibility to heart disease and stroke?
A team of South Australian researchers has cracked a rare gene variant for a disorder that causes severe neurodegeneration in infants.advertisement The previously baffling condition sees a normal healthy child start to lose muscle tone and motor skills, ultimately losing the capacity to walk and use language. The children go on to experience epileptic encephalopathy […]Read More The rare genetic disorder identified in only 3 people worldwide
Using a targeted gene epigenome editing approach in the developing mouse brain, Johns Hopkins Medicine researchers reversed one gene mutation that leads to the genetic disorder WAGR syndrome, which causes intellectual disability and obesity in people. This specific editing was unique in that it changed the epigenome — how the genes are regulated — without […]Read More Genetic brain disorder fixed in mice using precision epigenome editing
