Researchers Try Using CRISPR To Genetically Engineer Zika-Resistant Mosquitoes
A new research study at the University of Missouri is using CRISPR gene-editing technology to produce mosquitoes that are unable to replicate Zika virus and therefore cannot infect a human through biting. Slashdot reader wooloohoo shared an announcement from Cornell’s Alliance for Science: Alexander Franz, an associate professor in the MU College of Veterinary Medicine, collaborated with researchers at Colorado State…

Identical Twins Are Not So Identical, Study Suggests
An anonymous reader quotes a report from The Guardian: Genetic differences between identical twins can begin very early in embryonic development, according to a study that researchers say has implications for examining the effects of nature versus nurture. Identical — or monozygotic — twins come from a single fertilized egg that splits in two. They are important research subjects because they…
Identical twins don’t share 100% of their DNA
On average, less than six genetic mutations set the twins apart. Source: https://www.livescience.com/identical-twins-dont-share-all-dna.html
Can mRNA Biotechnology be Adapted to Improve Flu Vaccines and Fight Cancer?
Reuters notes the “miraculous speed” of mRNA vaccines, while also calling it “a glimpse of what’s possible if it can be applied post-pandemic to treat cancer or rare diseases.” The vaccine market alone is worth about $35 billion each year, and investors apparently believe mRNA companies will capture around two-third of that, leading market researcher Bernstein to evalaute the combined worth…
Discovery of ‘Cryptic Species’ Shows Earth is Even More Biologically Diverse
A growing number of “cryptic species” hiding in plain sight have been unmasked in the past year, driven in part by the rise of DNA barcoding, a technique that can identify and differentiate between animal and plant species using their genetic divergence. From a report: The discovery of new species of aloe, African leaf-nosed bats and chameleons that appear similar to…

Biomarker of Alzheimer’s Found To Be Regulated By Sleep Cycles
Following a 2018 study demonstrating how disrupted sleep can accelerate the buildup of toxic plaques associated with the disease, scientists from Washington University School of Medicine (WUSM) in St. Louis have now identified a protein implicated in the progression of the disease that appears highly regulated by the circadian rhythm, helping them join the dots and providing a potential new therapeutic…
Boston Biotech Conference Led To 245,000 COVID-19 Cases Across US
An anonymous reader quotes a report from CNN: A biotech conference in Boston last February that’s already been flagged as a Covid-19 superspreading event led to at least 245,000 other cases across the US and Europe, a new genetic fingerprinting study shows. One single case seems to have been responsible for many of the other eventual cases, the team at the…
