Ask KHN (Kaiser Health News) - PolitiFact: Is My Cloth Mask Good Enough? The 2022 Edition
“An effective mask has both good fit and good filtration,” the state said in its guidance. “A well-fitted mask has no gaps between the face and mask, such as above the nose or at the sides. With gaps, air that has virus particles can easily leak in or out around the sides of the mask. Good fit forces the air that you breathe out and breathe in to go through the mask and be filtered. Good filtration blocks the virus particles from going through the mask itself. You can get good filtration with the right materials and by using more layers.” "Multiple experts we consulted said that the current CDC guidance does not go far enough. They also agreed on another point: Wearing a cloth mask is better than not wearing a mask at all, but if you can upgrade — or layer cloth with surgical — now is the time." more »
Jerome Powell's Testimony at His Nomination Hearing for a Second Term as Chair of the Board of Governors of the Federal Reserve System; A Link to The Beige Book
"Congress provided by far the fastest and largest response to any postwar economic downturn. At the Federal Reserve, we used the full range of policy tools at our disposal. We moved quickly to restore vital flows of credit to households, communities, and businesses and to stabilize the financial system.
These collective policy actions, the development and availability of vaccines, and American resilience worked in concert, first to cushion the pandemic's economic blows and then to spark a historically strong recovery. Today the economy is expanding at its fastest pace in many years, and the labor market is strong." more »
Rose Madeline Mula Writes: I’ve Got A Secret – NOT!
"I always contended that if not revealing my age would actually make me younger, I would be as tight-lipped as the enigmatic Mona Lisa; but since nothing can actually erase the years, why not just accept and admit them?... Above all, almost all my friends would submit to waterboarding before revealing their age, blissfully unaware that these days that statistic is available to anyone who makes a simple Google query or two. They don’t realize that the mere fact that they don’t know that identifies them as ancient and that exactly how ancient is no longer a secret. They believe they can guard that number to the bitter end — and beyond. No exaggeration. One woman I knew made her son vow not to put her date of birth on her headstone when she died." more »
A Tisket, A Tusket: A New Study and Fossil Dental Exams Reveal How Tusks First Evolved
“Dicynodont tusks can tell us a lot about mammalian tusk evolution in general,” says Ken Angielczyk. “For instance, this study shows that reduced rates of tooth replacement and a flexible ligament attaching the tooth to the jaw are needed for true tusks to evolve. It all ladders up to giving us a better understanding of the tusks we see in mammals today.” “Tusks have evolved a number of times, which makes you wonder how — and why? We now have good data on the anatomical changes that needed to happen for dicynodonts to evolve tusks. For other groups, like warthogs or walruses, the jury is still out,” says Christian Sidor, a curator at the University of Washington Burke Museum and one of the paper’s authors.
