Traces of Ancient Epidemic Detected in DNA
TUCSON, ARIZONA According to a
Science News report, traces of a viral epidemic some 25,000 years ago have been detected in the DNA of present-day East Asians. Evolutionary geneticist David Enard of the University of Arizona and his colleagues analyzed more than 2,000 publicly available DNA samples from Chinese Dai, Vietnamese Kinh, and African Yoruba people for more than 400 proteins known to interact with coronaviruses. The researchers found that only the East Asian groups showed substantially increased production of all of the proteins. Analysis of the genes related to the production of these proteins suggests they became more common about 25,000 years ago and then leveled off about 5,000 years ago. This indicates that East Asians could have adapted to the infection, or the virus became a less potent cause of disease, Enard explained. Some of the gene variants would have also been useful for fighting other types of viruses as wel
University of Gothenburg Artificial intelligence could be one of the keys for limiting the spread of infection in future pandemics. In a new study, researchers at the University of Gothenburg have investigated how machine learning can be used to find effective testing methods during epidemic outbreaks, thereby helping to better control the outbreaks.
In the study, the researchers developed a method to improve testing strategies during epidemic outbreaks and with relatively limited information be able to predict which individuals offer the best potential for testing.
“This can be a first step towards society gaining better control of future major outbreaks and reduce the need to shutdown society,” says Laura Natali, a doctoral student in physics at the University of Gothenburg and the lead author of the published study.
CROW AGENCY, Mont. - Less than two months after a child s body was discovered on Crow Reservation, two women are convicted in tribal court of charges in connection to the disappearance of 8-year-old Mildred Old Crow.
Veronica Dust and Roseen Old Crow are convicted of endangering the welfare of a child and custodial interference.Â
Both women are sentenced to 18 months in jail and will be required to pay a $2,000 dollar fine.
Both charges are misdemeanors, the only type of charges allowed to be tried in Tribal court.
Crow tribal prosecutor Dave Sibley says the charges are connected to the disappearance of 8-year-old Mildred Alexis Old Crow.
The Chinese government has displayed a sense of responsibility, a quick response to people's needs and the ability to manage and coordinate during the COVID-19 epidemic, especially during the days when Wuhan, the hardest hit city on the Chinese mainland, was sealed off last year, said African students who stayed at their universities in Wuhan during the outbreak.
