My roommate recently showed me this map of univariate distributions and I think it’s awesome. Here is a snapshot:
It visualizes the relationship between different univariate distributions. Admittedly, it is somewhat useless if you don’t know exactly what you’re doing before looking at it. So not sure this will be the first place where I look up stuff about distributions. They do have summaries for all distributions if you click on them, but … more
A lot has happened in terms of research on the coronavirus. Here is a quick overview on what might be useful or interesting information:
Some sources: The role of vitamin D in the prevention of coronavirus disease 2019 infection and mortality, Focus on Vitamin D, Does vitamin D status impact mortality from SARS-CoV-2 infection?, The role of diet and nutritional supplements during COVID-19… more
Update: there is now a petition
Scott Alexander, the author of the Slate Star Codex blog, has deleted his entire blog in reaction to the New York Times threatening to publish an article about him. Scott has written one of the most consistently brilliant and insightful blogs on the internet (I honestly haven’t seen a better one, I’ve linked to it e.g. here, here and here) and I do feel this is a personal loss.
Scott hasn’t done … more
I recently stumbled across a study titled Personality Stability From Age 14 to Age 77 Years by Harris et al.. The study examined the personality traits of 1208 14-year olds in 1947. 63 years later, they followed up with the participants who agreed (n = 174). Their interesting result: The authors found virtually no correlation between most of the six character traits respondents were rated on. After correcting for various confounders they find that only ‘Stability of Mood’ remained somewhat … more
I recently learned about a cool website called Retraction Watch. They do exactly what the name suggests: They track papers that get retracted to highlight things that go wrong in the scientific process.
One post for example talks about a Covid-19 related article that got accepted within three days to nature Cellular & Molecular Immunology (213 000 views, still online as of June 16, 2020), but is taking more than two months to retract. Major flaws have been shown … more
I have previously written about the programmed death of organisms and about efforts to reverse aging. Now a new study is out and it is exciting. One implication of it is that donating blood might help to stay young. But let’s start from the beginning.
Generations of scientists and philosophers have conceptualized aging as the accumulation of random cellular damage. Your cells work fine, then you get a sunburn and you cell is damaged a bit. It recovers, but … more
Police violence is wide-spread problem – not only in the US but in other places as well. While I’ve read some pieces about body cameras, there was generally not a lot of discussions about measures we could take to curb it. I therefore found this Twitter thread about how to reduce police violence highly interesting. Some things they suggest:
I stumbled across this interesting article called Most Academic Advertising Is Immoral Bullshit. It makes the interesting point that most of what university advertises has very little actual evidence for it. The authors invite you to compare this with a medical treatment and ask you to imagine a drug called “Collegra”:
… moreCollegra is a drug unlike any other. If you take Collegra 256 times a year for four years, Collegra will improve your critical reasoning, moral reasoning, analytic, and
This article gives a very interesting overview of different types of candidates for a coronavirus vaccine: https://blogs.sciencemag.org/pipeline/archives/2020/04/15/coronavirus-vaccine-prospects
