A massive new study is uncovering the effects of genes and environment in over 500 different conditions. Targeting over 50,000 twin pairs, the research is the first of its kind to use large-scale data analysis to evaluate the heritability of such a broad range of conditions...

It's generally understood that the biological sex of an embryo is determined by the chromosomes at conception – two X chromosomes will develop as female, while an XY combo will become male. But this simple rule may be too simple. A new genetics study out of Australia has identified extra pieces of the puzzle that could explain some disorders of sex development (DSD)...

In one of the largest studies ever completed investigating the genetic origins of acne, researchers have homed in on several genetic regions that could be associated with the condition. Fascinatingly, it was revealed that many of these genetic regions are also associated with hair follicle function, highlighting a novel mechanism that may be targeted for new acne treatments in the future..
Naturally, mammals can only reproduce sexually – which has its upsides of course, but it makes us a little less adaptable than other species that can do things by themselves. In investigating why that's the case, Chinese researchers have successfully managed to breed healthy mice with genetic material from two mothers, using stem cells and gene editing...

Using data from nearly half a million people, a team of researchers has developed what they are calling a Genomic Risk Score (GRS), which can assess a person's genetic risk factor for developing coronary heart disease. The test will allow doctors to combine a GRS with other risk factors to better target at risk individuals...

New study probes the genetic roots of transgender identity
Posted by ArielTechGeek 136 days ago (https://feeds.feedblitz.com)
A new study led by researchers from the Hudson Institute of Medical Research in Australia has identified twelve significant genetic differences between transgender women and non-transgender males. These genes, known to be involved in sex hormone signaling, are hypothesized to possibly contribute to a person's ultimate sense of gender identity...

Genetic technique improves visual learning in mice with autism
Posted by ArielTechGeek 145 days ago (https://feeds.feedblitz.com)
A fascinating new study from scientists at UCLA has proposed a novel strategy to help autistic individuals improve their ability to process visual information. The experimental technique, demonstrated in mice, found that certain dysfunctional cells in the visual cortex can be genetically "tuned" to better respond allowing improved visual and sensory learning abilities...

Genetic study reveals how anglerfish light up the deep
Posted by ArielTechGeek 211 days ago (https://feeds.feedblitz.com)
Anglerfish are famous for their head-mounted bulbs that light up the inky blackness of the deepest oceans, but exactly what's going on in that process is still relatively unknown. To find out, researchers from Cornell University have now sequenced the genome of the bacteria that live inside those lightbulbs, and found a strange story of symbiosis still in progress...

A strong research paper from scientists at the Wellcome Sanger Institute has again raised doubts over the safety and accuracy of the CRISPR-Cas9 gene editing technique. The study suggests that the gene editing process can cause extensive unforeseen and unpredictable alterations to DNA sequences outside of the intended targets...

Humanity might not go out with a bang, but a sniffle – at least if the terrifyingly-plausible "superbug" scenario comes to pass. As bacteria increasingly evolve resistance to antibiotics, we could be cast back into "the dark ages of medicine" in the next few decades. But now we might have a new way to fight back. Researchers at Oxford University have discovered a "genetic catalyst" that le
