They look like mock strawberries to me because the seeds project out rather than being in a dimple.

Mock strawberries taste very watery. Not necessarily gross, but not really desirable either.

    It went from 1 pound air loss per day to 2 pounds per day.

    So it is significant in the statistics sense. That is a very measurable and sudden change which definitively shows that either a new leak has occured, or an existing leak has suddenly worsened.

    However, 2 pounds per day loss is not severe on its own. Presumably the worry is that without knowing what caused the sudden increase, they can't know whether a sudden and much worse intensification of losses will occur. So the astronauts not involved in repair activities should be ready to evacuate until the situation is fully evaluated and a repair plan is ready.

    Oxygen generators recycle CO2 back into O2. They can't create new air. So lost air is replaced from compressed gas storage tanks that get replenished from supply flights. 2 pounds per day is easy to supply from the tanks. The issue here is not knowing why there is a sudden doubling of losses and therefore lacking confidence that the situation won't worsen rapidly.

    Bad headline from the Guardian on this one.

    There's a big difference between evacuation readiness and evacuation.

    There was a sudden, but not catastrophic increase in air loss from 1 pound per day to 2 pounds per day. Until the source of the loss increase is found, NASA doesn't know if this is new damage such as from a micrometioroid impact or if existing damage is growing. Like a leaking dam, damage in weakened metal can grow rapidly without warning. So the astronauts not involved in the repair efforts are ordered to be ready for evacuation if the situation starts worsening rapidly.

    I personally expect the source of the leak to be found and repaired without evacuation.

    EDIT: the leaks have been identified and repairs are underway. NASA has ordered the astronauts back to normal operations. This is yet another of "abundance of caution" measures being sensationalized by media.

    I wish inverter type microwaves were standard. The vast majority of residential microwave ovens only modulate on like a 10 second interval. So you put it on power setting 3 or 30 and it will pump out full power for 3 seconds then off for 7 seconds. This works for things like defrosting meat, but a bunch of foods will still start popping and drying out in those few seconds. Inverter microwaves modulate many times a second so they can warm much more fragile foods without searing them.
