Bitcoin seems largely a ‘psychological’ currency whose value oscillates mostly in response to changes in folk’s opinions rather than shifts in some real underlying store of value, imo https://bitcoinmagazine.com/articles/when-fork-forks-what-yo…-goes-war/ https://paper.li/e-1437691924


Here’s what you need to know to get up to speed.

As a quick reminder, what is Bitcoin Cash again?

Bitcoin Cash (sometimes referred to as “Bcash” or “BCH”) is a cryptocurrency that split off from the main Bitcoin blockchain in August 2017. Culminating from Bitcoin’s years-long scaling dispute, the spinoff project most notably increased its block size limit through a contentious hard fork upgrade, “forking off” to become its own coin — though some of its proponents see it as the “real Bitcoin.” While currently trading at a fraction of bitcoin’s value — around $480 at the time of writing — Bitcoin Cash is the fourth biggest cryptocurrency by market cap and has garnered support from big names in the cryptocurrency space like bitcoin.com CEO Roger Ver and Bitmain co-founder Jihan Wu.

Still, the data trove has enabled Science, working with Retraction Watch, to gain unusual insight into one of scientific publishing’s most consequential but shrouded practices. Our analysis of about 10,500 retracted journal articles shows the number of retractions has continued to grow, but it also challenges some worrying perceptions that continue today. The rise of retractions seems to reflect not so much an epidemic of fraud as a community trying to police itself.


Better editorial oversight, not more flawed papers, might explain a flood of retractions.

Due to unfavorable weather conditions, the launch of Northrop Grumman Corporation’s #Antares rocket with #Cygnus cargo spacecraft is now targeted for 4:01 a.m. EST on Saturday, Nov. 17 from NASA’s Wallops Flight Facility. The spacecraft will deliver more than 7,400 pounds of science & research, crew supplies and hardware to the International Space Station. Get the latest updates: https://go.nasa.gov/2qW8lJb

The company-funded animal test was performed to ascertain how neural development is affected by the pesticide chlorpyrifos, which is used on a wide variety of crops around the world, including some 20 EU countries. The test laboratory concluded that there was no such effect, even at high doses.


Academic researchers have examined raw data from a company-funded safety evaluation of the pesticide chlorpyrifos. They discovered an effect on the brain architecture of the exposed laboratory animals at all tested doses, which was not included in the reported conclusions. Karolinska Institutet in Sweden led this independent study, which is published in the scientific journal Environmental Health.

All pesticides must be evaluated in terms of their safety and potential risks for human health before they can officially be approved. Normally the companies that manufacture the products cover the cost of such evaluations and commission test laboratories to perform the necessary animal tests.

Assistant professor Axel Mie at Karolinska Institutet, Christina Rudén at Stockholm University and Philippe Grandjean at Harvard School of Public Health have examined a case in which independent research and company-funded tests deviated, at least in terms of the conclusions drawn in the industry-funded study.

Chemical substances and nanomaterials are processed on a massive scale in diverse products, while their risks have not been properly assessed. Time and again synthesised substances have been shown to pollute the environment more than lab tests predicted. This is the warning given by Professor of Ecotoxicology Martina Vijver from Leiden University in her inaugural lecture on 16 November.

Laboratory tests are inadequate, according to Vijver, because they do not imitate a complete ecosystem. In her inaugural lecture she will discuss in greater detail two examples of substances where more realistic research is needed: agricultural toxins and nanoparticles. ‘But the same can be said for many other groups of substances, such as antibiotics, plasticizers and GenX.’
