"The office concluded Canadian Tire had attempted to convince consumers that sale items were on deep discount by including an artificially inflated regular price on its advertising material. Analysis of sales data showed that the products in question were rarely sold or advertised at the […]

Out of curiosity, does anyone happen to know how far the price of #bitcoin has to fall before the people "mining" it lose money?

The CIA just stopped publishing their World Factbook and took every page, including the archived copies of previous versions! This sucks. It was public domain, so I recovered the 2020 edition (the last one published as a zip file) and shared it to GitHub […]

One thing I've learned from history is that we don't seem to learn much from history.

Science does not need more papers; it needs better science. It needs time for careful thought, space for failure, and the freedom to pursue questions that cannot be answered in a few months. https://research-reviewer.blogspot.com/2025/10/publish-or-perish-research.html?m=1

This should be the mainstream #marketing position.

Marjolijn Heemstra asked us to think about what the moon needs from us rather than to always think about what we need from the moon. It has been a cultural icon for humans through history and is now commercialised. Fun fact: For billions of years it has given us the time, now we try to define a […]

"'’Backwards’ was my first thought,' said Cathy Holtslander, director of research and policy at the National Farmers Union (NFU), after learning about the email. 'Obviously, they made these cuts without knowing what they were doing — which is a big problem — and also [the cuts] suggest they […]

Canadian farmers are harvesting record spring wheat and canola crops, driven largely by widespread no-till and zero-till farming that locks in soil moisture and cuts erosion. Longer term, yields are up 77% for wheat and nearly double for canola since the mid-1990s. As the world’s largest canola […]

This is the most astonishing graph of what the Trump regime has done to US science. They have destroyed the federal science workforce across the board. The negative impacts on Americans will be felt for generations, and the US might never be the same again. www.nature.com/immersive/d4...

Retraction data are still useless – almost Retractions of scholarly articles are a rare event, affecting only about 0.02-0.04% of articles in total (but yearly rates are going up dramatically). This means that data about retractions are not even close to being representative of the scholarly […]

Danish CEO Lars Christensen posted the following statement about the change in US policy and I think it somewhat reflects how Europe sees the ongoing situation.
