Indeed, correlations are not sufficient to establish cause. However... things that do cause a specific effect also tend to correlate. So correlations are a basis for hypotheses that can be experimentally tested. To wit, the hypothesis prese

Correlation suggests causation, but does not prove it.

I doubt it because if it were caused by an infection, one would expect infections to cause Alzheimer's disease-like conditions more generally. If it is caused by a specific infection, then one would expect such a specific infection t

The problem really lies with the fact that within the more than 100,000 published studies on Alzheimer's disease you are bound to find a random association between this disease and many other things. This is especially true for observa

The people who benefit are those who can raise funds/support for the next round. It is more difficult to obtain objective evidence about biological sciences and its subset, medicine, than other fields such as maths or chemistry. This i

In the pharmaceutical business at least, huge sums of money are frequently spent on strategies that even graduate students could point out as being unlikely to succeed. The reasoning behind these unproductive decisions is almost always &quo

From the article: "causality between an increase in metastatic disease and the use of active monitoring versus treatment was established." The notion that monitoring PSA levels can per se increase the risk of metastasis is ridicul

We don't have self-driving trains yet, except in very tightly controlled environments. So I think it's going to take more than a few test runs to show that self-driving trucks will displace drivers anytime soon.

I somewhat agree with you here. In fact, as soon as the article starting drifting into lists, I stopped reading and scanned the rest.

Evidently, a $10M investment that compounds at 12% p.a. will return $31M after 10 years. The article however shows that dilution of that initial "round A" investment by subsequent rounds of capitalization needs to be taken into ac

Actually, the survival curve of the population is "squaring" [1]. That means that even while the average age of the population is increasing, the age of the oldest is not increasing at the same rate. The consequence is that the re

Why does someone who is 30 yrs old have a right to make policy for one who is 70, but not vice versa? It's a democracy, you know. By the way, it is the boomer generation that coined the term "Never trust anyone over 30.". Iro

Most likely the oil is shipped in large containers and bottled in the US. So the labeling will fall under US jurisdiction, not EU.

Isn't that a problem with US regulations and enforcement, rather than EU ones?

I guess it depends on the sense in which "productivity" is being used. A remote dev working for a Bay Area company from Spain can be just as productive for his employer as one located in Los Gatos, CA. However the above method wou

This way of estimating a dev's likely productivity would operate independent of their individual ability, as well as be applicable across all worker categories. For example a dairy farmer in Switzerland earns more than one in Poland be

GDP per capita seems to be a curious way to estimate if a local dev is likely to be productive. Would a Luxembourgish, Swiss or Norwegian dev be expected to be more productive than one from the US or UK? It seems to me that the prime determ

If anything, veterinary medicine is more often more scientific that human clinical medicine due to the greater ease with which experimental approaches can be performed on animals compared to humans.

The English are masters of the subtle insult, though. This is usually illustrated by quoting Churchill, for example: Bessie Braddock to Churchill -- "Winston, you're drunk!" Churchill: "Bessie, you're ugly, and tomo
