Neanderthals may have had a lower threshold for pain: People who inherited a special ion channel from Neanderthals experience more pain

As several Neanderthal genomes of high quality are now available researchers can identify genetic changes that were present in many or all Neanderthals, investigate their physiological effects and look into their consequences when they occur in people today. Looking into one gene that carries such changes, Hugo Zeberg, Svante Pä

Ancient part of immune system may underpin severe COVID

Among other findings linking complement to COVID, the researchers found that people with age-related macular degeneration -- a disorder caused by overactive complement -- are at greater risk of developing severe complications and dying from COVID. The connection with complement suggests that existing drugs that inhibit the complement system could
