How did the corona virus break out? Theories abound as researchers attempt to solve genetic detective stories

Scientists have come together across international borders to condemn nationalist conspiracy theories. And yet they are divided over what was once considered the most likely culprit: a so-called wet market in Wuhan, where wild animals are kept in cages and sold as pets or feed. It is believed that an animal infected with bats – perhaps a pangolin – infected …

UCSF’s genetic analysis finds many COVID-19 strains in California

Where does the COVID-19 virus come from in the Bay Area? All over. There is not a single smoking weapon. Not a lonely patient zero. No case has triggered an epidemic that has now infected more than 11,000 people and killed nearly 250 Californians. A new genetic analysis from UC San Francisco discovered at least eight different virus lines in …

Modern humans, Neanderthals share a confused genetic history, study confirms

Comparison of modern human and Neanderthal skulls from the Cleveland Museum of Natural History. Photo credit: DrMikeBaxter / Wikipedia In recent years, scientists have found evidence that modern humans and Neanderthals share a confused past. In the course of human history, these two types of hominins do not only cross one another, but several times, according to thinking. A new …

DNA could be one in a million possible genetic molecules

Saturn's moon Enceladus, where we hope there are aliens. Image : NASA / JPL-Caltech / Space Science Institute [19659004] According to a recent article, there could be a million different structures that can store genetic information. DNA stores the genetic information that describes the entire life of the Earth in the form of a twisted framework that is lined with …

In order to survive in the human gut, bacteria need a genetic "passcode"

Abstract Bacteria need a number of specialized genes to live in the human gut – and the composition of these genes varies from person to person. Therefore, efforts may need to be made to improve the health of the microbiome, including next-generation probiotics. The human gut is a dangerous place to exclude toxins to deter microbial invaders. However, every human's …
