Just because a planet is in its star’s Goldilocks zone doesn’t mean it’ll be capable of supporting an Earth-like biosphere. A new study focuses on the amount of radiation in the wavelengths usable by photosynthetic plants; “the team discovered that stars around half the temperature of our Sun cannot sustain Earth-like biospheres because they do not provide enough energy in the correct wavelength range. Oxygenic photosynthesis would still be possible, but such planets could not sustain a rich biosphere.” Red dwarfs—where many exoplanets have been discovered—have only a third the Sun’s temperature; stars that are brighter and hotter than the Sun have lifespans too short for life to have a chance to evolve. In other words, the Sun is in a very narrow sweet spot. [Universe Today]
The COVID-19 situation in the Pontiac is much improved, with five or fewer active cases at the moment and no new cases reported anywhere since last Friday. The outbreak we were dealing with in April was more or less brought under control in May, though there was a bit of a rebound in the Bryson/
I’ve been using fountain pens on and off since I was in university; about a year ago that interest got a good deal more serious (it was the pandemic and I needed a distraction), and between us Jen and I began accumulating pens and inks at a ridiculous rate. Two of our first bottled inks were blue inks with some unusual qualities; after a year of using them fairly frequently, I have some thoughts about them.
Since I posted two weeks ago that we weren’t doing that well out here COVID-wise, I thought I’d mention that things are now looking a bit better. We only had 14 new cases over the past week, compared to 51 new cases two weeks ago. Almost all of those new cases—11 out of 14—are in the Fort-Coulonge/Mansfield area, whose local outbreak may actually be showing signs of running out of steam. Shawville hasn’t had a new case in a week, Campbell’s Bay longer than that. The special emergency measures come to an end on the 17th, as they do for the rest of the Outaouais, at which point we’re back in the red zone.
Having spared us during the first wave—during which we were behind police checkpoints that turned back non-essential traffic—and being under relatively good control during the second, COVID-19 has just erupted in the Pontiac MRC during the third wave. In the space of one month the number of people who have tested positive has more than quadrupled, from 39 on March 25 to 173 today.1 This is mainly due to a major outbreak in the Fort-Coulonge area: Fort-Coulonge went from fewer than 5 cases2 to 34; Mansfield-et-Pontefract from 7 to 64. Together they make up more than half the cases in the Pontiac MRC while comprising only a quarter of the population.
These numbers may not seem like a lot—a total of 1.2 percent of the Pontiac MRC’s population has tested positive for COVID as of today, compared to Gatineau’s 3.2 percent or Quebec’s 4 percent, and with our small population (14,251 according to the 2016 census) the raw numbers are pretty small in comparison. But to reiterate: more than three-quarters of the our total COVID cases have come just in the past month. Cases are increasing by 30 percent a week—and 30 percent of this week’s numbers is a lot more than 30 percent of a month ago. This is how exponential growth works.
Meanwhile, last Friday the Pontiac Hospital—the front door of which is less than 300 metres from my home—reported an outbreak in its acute care ward: nine patients and three staff members tested positive initially; that number has since risen to 17 patients and 13 staff. For context, the ward has 34 beds. Fortunately some have been vaccinated, and some have tested positive without showing symptoms, so this may turn out to be the best possible version of the worst possible scenario. But still: the whole point of last year’s checkpoints was not only to keep COVID out of our community (which tends older and in poorer health than the Canadian average); it was to keep it out of our hospital.
So yeah. We could be doing better out here.
