Can I create my own filter? Some people buy or create masks with a pocket inside to hold a filter, such as a coffee filter. When using other materials to make your own filter, such as unused vacuum cleaner bags, HEPA furnace filters, HVAC anti-allergy filters or other air filters, make sure you sandwich the filter between at least two layers of fabric to cut down on the risk of inhaling potentially harmful fibers from these materials. There are not yet conclusive data on whether or not filters provide added protection, but studies are underway. Please make sure that you can breathe easily when wearing the mask, and do not use a filter if it makes you feel short of breath. more »

There’s no standard federal ratio of staff to residents. A 1987 law requires nursing homes to have a registered nurse on duty eight hours a day, seven days a week; a licensed nurse on duty in the evenings and overnight; and staff “sufficient to meet nursing needs of its residents.” There’s no national data on nursing home staffing during the pandemic, because the federal government has suspended staff reporting requirements to give businesses a break from paperwork. Before the pandemic, the average nursing home could provide 3.9 hours a day of nursing care per patient, according to the most recent federal data. more »

Can we really tell male and female dinosaurs apart? Scientists worldwide have long debated our ability to identify male and female dinosaurs. Researchers analysed skulls from modern-day gharials, an endangered and giant crocodilian species, to see how easy it is to distinguish between males and females using only fossil records. Male gharials are larger in size than females and possess a fleshy growth on the end of their snout, known as a ghara. The research teamstudied 106 gharial specimens in museums across the world. They found that aside from the presence of the narial fossa in males, it was still very hard to tell the sexes apart. more »

Rose Madeline Mula writes: I have thought about whom I would like to be isolated with if given the chance. Obviously, my first choice would be those I love — especially any of them who can cook. Other than that, who? No, not George Clooney. There would be way too much pressure to try to look good 24/7. Instead, it would be very handy to have a tech support guy or gal ensconced in the guest room to solve my inevitable computer glitches ... a plumber (clogged toilets are my nightmare, second only to a shortage of toilet paper) ... an electrician (in case of a repeat of my recent smoke detector catastrophe when all three failed simultaneously on a Saturday night and each screamed “EVACUATE!” every five seconds) ... And if one of these guys or gals knows how to fold a fitted sheet, that would be a big plus. more »
