'Superpower' that kiwis detect vibrations in the grounds evolved from birds 70 MILLION years ago

Because the ancient birds hunted lizards and fish, and did not dig for worms, the team suggests the trait started as a facial sensitivity and evolved into the beak organ called the bill-tip organ.However, a structurally-similar, but functionally mysterious, bill-tip organ is also found in ostriches, emus and their relatives the paleognaths, an ancient group of birds.The team not only believes remote-touch evolved early in modern birds, like ibises (pictured) but possibly from the from snout tactile specializations of their non-avian dinosaur ancestors.And this facial sensitivity may have been the start of the specialized bill-tip organ observed in today's ibises and kiwis.We've been able to show that the Mesozoic ancestor of ratites (such as, ostriches, rhea, and emu) was a probe-feeding bird like modern ibises and kiwi. read more...

'Autoantibodies' may be driving severe Covid cases, study shows

Further tests revealed that the more autoantibodies patients had in their blood, the worse their disease.The Covid-19 patients had more antibodies that had turned on them than people with lupus, an autoimmune disease caused by similar wayward antibodies.Covid-19 patients make autoantibodies that actually interfere with immune responses against the virus, said Aaron Ring, an immunobiologist at Yale and senior author on the study.Ring said that if Covid-19 autoantibodies endure in the body they might play a part in long Covid.A big part of our lab direction of travel for the coming months is trying to relate long Covid symptoms to autoimmune profiles, he said. read more...
