The team’s study also analyzed the function of the gut bacteria and found that the Treponema species in the Matses are most like those in the guts of pigs. There, the microbes play a role in digesting carbohydrates, or sugars. This suggests that the existence of Treponema “is likely a good indicator of a general high level of microbial diversity in the human gut,” says evolutionary anthropologist Stephanie Schnorr of the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany. “Now it seems clear that their function is related to helping metabolize carbohydrates, and this can have a number of benefits and implications for host health.” … [Read more...] about Ancient bacteria found in hunter-gatherer guts

"There is absolutely no evidence whatsoever that companion animals play any role in the epidemiology of this disease," said Trevor Drew, director of the Australian Animal Health Laboratory. Drew and his colleagues at the AAHL are testing vaccines in ferrets in pre-clinical trials to assess safety and efficacy of new treatments. Ferrets are used in the trial because they are particularly susceptible to infection by the coronavirus. However, even ferret owners are unlikely to get the disease from their furry friends according to Drew. … [Read more...] about Coronavirus and pets: How does COVID-19 affect cats and dogs?
Certain cultural practices may also be contributing to more zoonotic diseases. For example, many people in the U.S. practice hunting and "in a lot of places in the world, that is the main source of protein," Han said. Putting pressure on the environment through hunting and development throws the ecosystem off balance, she said, and makes it harder for animals to survive as they were. The animals are forced to travel farther and search harder for food or mates, and in this chronically stressed condition, those animals are more susceptible to disease and more likely to spread disease to humans, Han said. Such hunting practices also provide more opportunities for people to become exposed to zoonotic diseases. … [Read more...] about What are zoonotic diseases?
Other criteria laid out by Jewish law require "no contact" utensils. In other words, utensils cannot be used to prepare kosher meats if they have interacted with dairy, eggs or nonkosher food. In fact, Jewish people who follow kashrut avoid eating meats and dairy products together, and some even wait a certain amount of time before consuming one after the other, according to the Biblical Archaeological Society. … [Read more...] about What Is Kosher Food?
Aardman's view of the world is essentially one large English village, in which most conflicts come from absent-minded eccentrics whose eccentricities get in each other's way. Villains are few and far between, and they only exert the influence they do because the rest of us are too polite or timid to stand up to them. While Aardman short films focus on just a few characters, its features tend to star whole villages of cross-eyed but well-meaning dingbats. If it's not a village, it's a chicken coop or a pirate ship or a band of hunter-gatherers. The filmmakers have boundless affection for their googly-eyed subjects, forgive them their failings, and celebrate their idiosyncrasies. To quote Mozart, "love, love, love, that is the soul of genius." … [Read more...] about movie review: Stop-motion sheep > CG hedgehog
