New research published today in PLOS ONE reveals an improved annotation of microRNAs in the dog genome to further understand its biological role. Providing a platform for future studies into biomedicine, evolution and the domestication of important animals including dogs, cows, horses and pigs. This discovery provides a significant opportunity not only to enhance our understanding of how miRNAs regulate…
While research has identified hundreds of genes required for normal memory formation, genes that suppress memory are of special interest because they offer insights into how the brain prioritizes and manages all of the information, including memories, that it takes in every day. These genes also provide clues for how scientists might develop new treatments for cognitive disorders such as…
The genome of the Western lowland gorilla (Gorilla gorilla ssp. gorilla) has been sequenced at a high level of quality beginning to approach that of the human genome, says a team of scientists led by Prof. Evan Eichler from the University of Washington. Prof. Eichler and his colleagues used long-read sequencing technology, along with a unique combination of algorithms, to…
About eight percent of our DNA is viral in origin: remnants of ancient battles between infectious viruses and our ancestors. These so-called endogenous viruses are often perceived as a mere oddity with no clear biological significance. But a new study by scientists at the University of Utah School of Medicine shows that evolution has repurposed some of these viral remains into weapons…
New findings from Blombos Cave show that Stone Age man in Africa exchanged technology to a large extent. The more contact between groups, the stronger technology developed. The exchange of tools can explain humans journey from Africa to Europe. “The pattern we are seeing is that when demographics change, people interact more. For example, we have found similar patterns engraved on…
Companies advertise BPA-free plastic as a safer version of products ranging from water bottles to sippy cups to toys. Many manufacturers stopped using bisphenol A, a chemical that is used to strengthen plastic, after studies linked it to early puberty and a rise in breast and prostate cancers. However, bisphenol S, or BPS, a common replacement for BPA in plastics,…
