It has long been understood that being physically active is good for you, particularly when it comes to preventing things like heart attacks and strokes. Physical exercise may be even more important for the prevention of cardiovascular disease than previously known — and the more activity the better, a new large study led by the…

When one of my co-workers found out about a tiny, orphaned kitten that needed a home a few months ago, he didn’t hesitate to adopt it. He says his new companion helped make the months of Covid-19 isolation at home much less stressful. He is not alone. Animal shelters and breeders across the country have…

The US set a record Tuesday for the most Covid-19 deaths reported in one day since the start of the pandemic, according to data from Johns Hopkins University.

A new study provides early evidence that a Covid-19 vaccine might be effective against two new coronavirus strains first identified in South Africa and the UK, despite a concerning mutation. The two strains share a mutation known as N501Y that scientists worry could allow the virus to evade the immune protection generated by a vaccine. In research posted online…

On December 18, a San Diego emergency room nurse was given a shot of the Covid-19 vaccine. A week later, he tested positive for the virus, CNN affiliate KGTV reported.
