Имперский колледж Лондона опубликовал фотоэссе о том, как исследователи из департамента инфекционных болезней разрабатывают вакцину от COVID-19. Вот самые важные факты: Ученые разработали вакцину-кандидата за 14 дней после того, как получили расшифрованный геном вируса из Китая. Самоамплифицирующаяся РНК-вакцина, по сути, вводит новый генетический код в организм, подсказывая ему, как создать белок, который вызывает защитный иммунный […]

Of course, the first comment on the comic is this BS: Nobody gets to be a billionaire without creating something that millions, even billions, of people want and pay for. If you don’t like billionaires, then trying living your life without everything they’ve made possible for you. Reassuringly, that commenter will never be a billionaire, […]

I grew up in the Pacific Northwest, and no one ever told me about the Pacific folding trap-door spider. I sure never saw one. But this lucky woman out walking her dog saw one on the sidewalk and — oh what a waste — ran away. Experts say the spider she spotted is a Pacific […]

This looks like a good way to spend my time after classes are over, but I haven’t been able to find it in the Ikea catalog. Has it sold out already?

New York has given Franklin Graham the boot. After weeks of scrutiny, it was announced over the weekend that the Central Park tent facility run by Graham’s charity Samaritan’s Purse will be wound up, closing to new patients from May 4, before the site is disinfected and dismantled. The eight patients currently being treated at […]

I’ve always wondered what he looked like. You may be somewhat disappointed. You haven’t yet seen the mind behind that rather ordinary face, though, which will leave you a lot disappointed. A Republican Ohio state representative cited his religious beliefs to explain why he would not wear a mask as recommended by Gov. Mike DeWine […]

I was scheduled to get a routine physical a while back, cancelled for obvious reasons, and last week Stevens County Medical Center called me to come in for it today, which feels odd. I guess our local clinic has not been overwhelmed — there have been zero reported cases of COVID-19 in Stevens County, perhaps […]

I’m back from my doctor’s visit! It was nothing but good news. The outside walls of the clinic are covered with swarms of chironomid midges! Everywhere I looked, there they were, clinging to the brickwork. This is one big buffet for spiders that I’ll have to check again later, but I didn’t see many today […]

Skatje is working hard on her thesis in computational linguistics, and might not appreciate a joke about how easy it is. It’s hard enough that I don’t even understand what she’s doing when she tries to explain it!

Milo Yawannapissoff and Michelle Malkin have been collaborating, and the results are even more awful than you can probably imagine. They decided to work together to create an “America First” reading list for their followers. Just from their choice of subject you can tell it’s going to be a collection of racists’ greatest hits. Milo […]

“Venezuela!” is the reflexive argument of the right-wingers against socialism, so it’s not surprising that a cocky gang of American thugs would decide they could just swagger in and topple the Venezuelan government — 62 stupid mercenaries against a nation of 28 million people. They were so arrogant that the head of the mercenary organization […]

Like Minneapolis, the city of Mississauga is allowing mosques to broadcast the call to prayer during Ramadan, which seems reasonable, since 12% of the population is Muslim. The only problem is that some people are objecting, for bogus reasons. An open letter attached to three petitions, two of them hosted on Change.org, calls on Mississauga […]
