Junk DNA in birds may hold key to safe, efficient gene therapy

Retrotransposons found in the genomes of the white-throated sparrow and the zebra finch are shown to safely shepherd transgenes into the human genome, providing a gene therapy approach complementary to CRISPR-Cas9 gene editing. Credit: Briana Van Treeck, UC Berkeley The recent approval of a CRISPR-Cas9 therapy for sickle cell disease demonstrates that gene editing tools … Read more

Microplastics present in muscles, intestines of South East Queensland sharks

Microplastics present in muscles, intestines of South East Queensland sharks

Credit: Chemosphere (2023). DOI: 10.1016/j.chemosphere.2023.140957 Researchers have discovered not only microplastics but also a higher abundance of cellulose-based fibers in the intestine samples of four apex shark species caught off the coast of South East Queensland (SEQ). The finding sheds light on the potential food-chain transfer or direct ingestion of foreign materials by these marine … Read more

Lab-grown diamonds put natural gems under pressure

Lab-grown diamonds put natural gems under pressure

Man-made gems are reshaping the $89 billion global diamond jewellery market. The glittering diamonds sparkle the same but there are key differences: mined natural gems are more than a billion years old, while laboratory-made rocks are new and cost less than half the price. Man-made gems are reshaping the $89 billion global diamond jewelry market, … Read more

Why two prehistoric sharks found in Ohio got new names

Why two prehistoric sharks found in Ohio got new names

Loren Babcock with a collection of Orton Museum’s fossil fishes, including several from John Newberry. Credit: The Ohio State University Until recently, Orthacanthus gracilis could have been considered the “John Smith” of prehistoric shark names, given how common it was. Three different species of sharks from the late Paleozoic Era—about 310 million years ago—were mistakenly … Read more
