Preliminary reports of a dog origin alpha canine coronavirus infecting people are alarming. Scientific diligence is needed to confirm the species jump and determine how much risk management is required, if any. We’re sharing three articles for your review and consideration. I think the more we look, the more we will find that these coronaviruses are crossing species … [Read more...]
Mammals can breathe through their intestines
Takanori Takebe, MD, PhD, and research colleagues hypothesized that oxygen can be absorbed by tissues in the rectum. Their tests in pigs and mice suggests oxygen could enter the bloodstream via mammalian intestines. Source: Science, May 14, 2021. Link. It looks like a crazy idea. But if you look at the data, it’s actually a very compelling story.” – Sean Colgan, … [Read more...]

How tuberculosis reshaped our immune systems
Tuberculosis has killed more people in the past 2000 years than any other disease, and it has sickened many more, writes Ann Gibbons. Archaeogenetic research helps identify which TB pathogens that have changed our DNA and made us more resilient. “Infectious diseases are the strongest evolutionary pressure humans have to face. . .” Source: Science, March 4, 2021. … [Read more...]
Lyme disease is getting skinked
Black-legged ticks in the southeast U.S. prefer to feed on lizards, particularly skinks. Skinks don’t transmit Lyme as easily as the white-footed mice in the northeast U.S. Jean Tsao, a disease ecologist, and her team found a clear divide in ticks’ preferred hosts and behavior south of Virginia, matching the pattern of both tick infections and Lyme disease.

Polyclonal antibodies being developed IN cows for Covid-19 virus
SAb Biotherapeutics of Sioux Falls, South Dakota, is pursuing an extension of previous research in genetically modifying dairy cows so that certain immune cells carry the DNA that allows people to make Covid-19 antibodies. Cows become giant bioreactor antibody factories. They have more blood engineered to synthesize human versions of the proteins and their blood can also … [Read more...]
