Friday 6/5 🐿  Physics & Squirrels An Entertaining QUARANTINE PROJECT.  NASA engineer  https://youtu.be/tgFebZNw2p8 https://youtu.be/8gQ84a273Wg https://www.sciencenewsforstudents.org/blog/eureka-lab/stalking-squirrels-science https://www.livescience.com/where-did-black-gray-squirrels-come-from.html Biologists from the United Kingdom think they've decoded the mystery of all the gray  squirrels  ( Sciurus carolinensis ) running around the United States with black fur. The bit of genetic code that causes the  gray squirrel  species to turn black, they showed, is an allele, or a variant form of a specific gene, called MC1R∆24. But that allele doesn't seem to come from gray squirrels. Instead, they showed, the gray squirrel MC1R∆24 allele is "identical" to the MC1R∆24 allele found in another species, fox squirrels ( Sciurus niger ) — one of two mutations that occasionally cause big, usually reddish fox squirrels to turn blac
