Spit, Don’t Rinse. Also Floss.

The more you know! Apparently, you should not rinse your mouth with water after brushing your teeth. Instead you should spit, in order to keep the fluoride from the tooth paste on your teeth as long as possible. Here is an article about it by the Oral Health Foundation: Spit, don’t rinse.

If you’re really ready to go down the rabbit hole of internet dental hygiene, here is an article stressing the importance of flossing.

Lab Safety and the Origins of Covid-19

three clear beakers placed on tabletop

Until this day the origins of the Sars-coronavirus 2 remain unknown. The two ends of the spectrum of theories are the zoonotic theory and the laboratory theory. The first states that the virus has evolved naturally from hosts such as bats and pangolins and recently started infecting humans as well. The assumed location for this is a wet market in Wuhan. The second one assumes that the virus has escaped (or maybe even was released intentionally) from a research lab. … more

Does Tobacco Cause Psychosis?

When people discuss cannabis, they usually also talk about its potential to cause psychosis. I have never heard the same about tobacco.

Recently, I stumbled across an interesting study. It suggests that tobacco and weed may be equally strongly associated with psychotic-like-experiences. I haven’t read the whole study, but via a quick google search I could find broadly the same result elsewhere: For example, there is a meta analysis in the Lancet Psychiatry that found

an overall relative risk


It Probably Wasn’t Fake News

I just read an article about the 2016 election that argued two things: First, fake news probably had very little effect on election outcomes. And second, the media actually did.

I liked the first part, because it confirmed what I already thought was true (see this short cartoon on confirmation bias for a little chuckle). Fake news only make a tiny fraction of all the news and I don’t think they are particularly effective. It is just genuinely hard to … more

How 70 Research Teams Came To Different Conclusions Based on the Same Data

70 research teams were tasked with analyzing the same identical set of functional magnetic resonance imaging (fMRI) brain scans. In many areas, they came to quite different conclusions. Ouch. This is not good. I mean, it’s maybe not as spectacular as finding brain activity in a dead salmon, but it’s not good.

Find a lighter article here and the nature paper here. Thanks to Robert for pointing me to it.

Is the Catholic Church a Force for Good in the World?

Stephen Fry delivers a powerful speech arguing why the Catholic Church is not a force for good in the world. The speech comes from the 2009 intelligence squared debate – which Stephen Fry kind of destroys completely. If you ever listen to a speech, listen to this one.

The relevant part starts at 21 minutes. This is a slightly edited version. The slightly more complete version is this, but the video is a bit pixelated.

Corona Aid to the Church

NEW YORK (AP) — The U.S. Roman Catholic Church used a special and unprecedented exemption from federal rules to amass at least $1.4 billion in taxpayer-backed coronavirus aid, with many millions going to dioceses that have paid huge settlements or sought bankruptcy protection because of clergy sexual abuse cover-ups.

The church’s haul may have reached — or even exceeded — $3.5 billion, making a global religious institution with more than a billion followers among the biggest winners in the


Is Sex Binary?

content note: discussion of biological sex and a binary classification thereof

two different gametes

Update: Maybe one point warrants a bit more clarification: I indeed believe that people use definitions as weapons. Especially definitions about sensitive topics. And this definitely is one. I also think that quite a few people who commented on this thread seemed to take this as a ‘gotcha moment’ to validate sometimes very problematic opinions regarding trans people. I do not endorse this – … more
