More than 35 years after the world's worst nuclear accident, the dogs of Chornobyl roam among decaying, abandoned buildings in and around the closed plant -- somehow still able to find food, breed and survive.

Its been really, really tricky to sort out.. At the University of Sao Paulo in Brazil, researchers have recruited 100 cohabiting couples where one was infected and symptomatic, while the other never tested positive and blood tests confirmed they carried no Covid-specific antibodies, meaning it's unlikely they have ever caught the virus. Here's what you need to know about the closures, plus what retail experts say about the company's exit from Canada. In the early days of the pandemic, a small, tight-knit community of scientists from around the world set up an international consortium, called the Covid Human Genetic Effort, whose goal was to search for a genetic explanation as to why some people were becoming severely sick with Covid while others got off with a mild case of the sniffles.

The discovery that some healthcare workers had pre-existing immunity to covid-19 could lead to vaccines that protect against a much wider range of coronaviruses.

A small but growing number of Americans are moving to New England or the Appalachian Mountains, which are seen as safe havens from climate change. Health officials also are warning about a recent uptick in cases, likely due to a combination of the BA.2 subvariant, waning immunity and the lifting of a number of provincial pandemic restrictions, including mask mandates.

By the time the team started looking for suitable people, they were working against mass vaccination programs too. WIRED may earn a portion of sales from products that are purchased through our site as part of our Affiliate Partnerships with retailers. Some viruses like SARS-CoV-2, she said, have evolved to specifically block or inhibit the production of these interferons, which can result in more severe infection. Genomewide association study of severe . Per NPR, a series of new studies have found that some people gain an extraordinarily powerful immune response to the novel coronavirus, which causes COVID-19. This could, in theory, be controlled. Such findings have spurred the study of people who appear to have stayed free of COVID-19 despite high risks, such as repeated exposures and weak immune systems. Its such a niche field, that even within the medical and research fields, its a bit pooh-poohed on, says Donald Vinh, an associate professor in the Department of Medicine at McGill University in Canada. Per NPR, a series of new studies have found that some people gain "an extraordinarily powerful immune response" to the novel coronavirus, which causes COVID-19.

Tom Sizemore, the 'Saving Private Ryan' actor whose bright 1990s star burned out under the weight of his own domestic violence and drug convictions, died Friday at age 61.
