Three domestic cats were inoculated with SARS-CoV-2 on day 0. One day after inoculation, a cat with no previous SARS-CoV-2 infection was cohoused with each of the inoculated cats to assess whether transmission of the virus by direct contact would occur between the cats in each of the three pairs. […] On day 3, one of the cats with no previous infection had infectious virus detected in a nasal swab specimen, and 5 days later, virus was detected in all three cats that were cohoused with the inoculated cats.

The evidence suggests that these are instances of human-to-dog transmission of SARS-CoV-2. It is unclear whether infected dogs can transmit the virus to other animals or back to humans. [Nature]
I’ve landed in Hong Kong after flying from Paris CDG, via London Heathrow. I now have to wait ~8 hours before I get my #COVID19 test results and thus have ample time to tweet about my experience. [Laurel Chor, Twitter]
Most elevators aren’t big enough to allow people to stay six feet apart, so there’s a chance that infected passengers could transmit the virus, particularly if they are unmasked and are coughing, talking or just came in from a jog and are breathing heavily. But even if you’re riding the elevator alone, there are other ways you might catch the coronavirus, although the risk is low. Elevator buttons and side rails are a potential risk if your hands become contaminated and you touch your face. […] If you step into an elevator after an infected person has been riding in it, can you breathe in floating germs? […] given the variety of elevators and buildings, there are thousands of scenarios that give different results. [NY Times]

Even mild dehydration can be a physical stressor to the body, according to Melissa Majumdar, a registered dietitian and spokesperson for the Academy of Nutrition and Dietetics. If we’re not adequately hydrated, we may experience nausea and loss of appetite, and may find it difficult to concentrate and perform physical tasks, like carrying groceries or lifting weights. The Institute of Medicine recommends that women aim to consume 2.7 liters (or 91 ounces) of fluids daily, and men drink 3.7 liters (or 125 ounces). But that recommendation doesn’t focus on water specifically. Rather, it includes all fluids and water-rich foods, including fruits, vegetables and soups. Considering that about 80% of our water intake comes from fluids and about 20% from foods, that breaks down to a daily goal of about 9 cups (or 72 ounces) of fluids for females and 12½ cups (or 100 ounces) for males.
Chekhov’s gun is a dramatic principle that states that every element in a story must be necessary, and irrelevant elements should be removed. Elements should not appear to make “false promises” by never coming into play.
