The Price of Remission: This Cancer Drug Saves Lives — but Costs a Fortune. I Wanted to Know Why. When I was diagnosed with cancer, I set out to understand why a single pill of Revlimid cost the same as a new iPhone. I’ve covered high drug prices as a reporter for years. What I discovered shocked ...

Revlimid has its origin in a pill that cost patients $7.50 each.

Decades later, the cancer drug costs more than $18,000 for a month’s supply — even though it still only costs about 25 cents to manufacture.

Tim Berners-Lee Invented the World Wide Web. Now He Wants to Save It In 1989, Sir Tim revolutionized the online world. Today, in the era of misinformation, addictive algorithms, and extractive monopolies, he thinks he can do it again.

While others wrung riches from the World Wide Web, Tim Berners-Lee assumed the mantle of moral authority, fighting to safeguard the web’s openness and promote equitable access. Can he do it again?

An array of 9 purple discs on a blue background. Figure from Hinnerk Schulz-Hildebrandt.

A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.

The effect presumably comes from the absence of S-cones in the fovea.

CRESTRICTED] ORIENTATION FACT SHEET 64 WAR DEPARTMENT-WASHINGTON 25, D. C. • 24 March 1945 FASCISM! Note For This Week's Discussion: Fascism is not the easiest thing to identify and analyze; nor, once in power, is it easy to destroy. It is important for our future and that of the world that as many of us as possible understand the causes and practices of fascism, in order to combat it. Points to stress are: (1) Fascism is more apt to come to power at a time of economic crisis; (2) fascism inevitably leads to war; (3) it can come to any country; (4) we can best combat it by making our democracy work.

In March of 1945, the US Army issued this "fact sheet" to guide conversations with soldiers on the topic of fascism, paying particular attention to the ongoing threat that domestic fascist movements posed to the US. Their analysis of what a homegrown US fascism would look like is interesting.

This may be the most important paper ever published about NIH funded research.

How the brain splits up vision without you even noticing As an object moves across your field of view, the brain seamlessly hands off visual processing from one hemisphere to the other like cell phone towers or relay racers do, a new MIT study shows.
