The novel coronavirus has infected more than 26.35 million people, with just four countries accounting for over 15 million cases. They are the United States, Brazil, India and Russia — the same four that have been at the top for months. The US surprised the world when it rose to the top spot in multiple COVID-19 statistics, both for the total number of confirmed cases and the number of deaths. Since then, no other country has surpassed America. Continue reading Scientists can’t explain puzzling lack of coronavirus outbreaks in Africa
The Greenland shark is one of the world’s largest marine species, reaching lengths over 19 feet. And yet these fish, which prefer the deep, cold waters of the Arctic and North Atlantic oceans, have largely eluded scientific study.

An Italian woman, her two daughters, and her three grandchildren have always had trouble feeling pain. They can’t sense temperature. They break bones without noticing. Now, a team of scientists in the United Kingdom think they’ve figured out why.
A team of scientists have snipped away HIV DNA from the genome of live mice using a CRISPR system, and the rodents lived to (kinda) tell the tale. It’s still much too early to call the method a possible cure, but the fact that it worked on a living animal opens up a lot of possibilities. Will it work on other diseases, like cancer? Maybe, but that’s something scientists have to look into. These researchers headed by neurovirologist Kamel Khalili have been focusing on the use of the gene-editing technique to eliminate HIV for years. They successfully excised HIV DNA in live mice last year, but this round is a lot more thorough.
