When Astronomers Chased a Total Eclipse in a Concorde
In the 1970s, a small group of astronomers used the first prototype of the Concorde to pursue a total eclipse across the Sahara at twice the speed of sound.

Science doesn’t explain tech’s diversity problem — history does
In this context, Damore’s memo is particularly sloppy and fundamentally unscientific. The memo doesn’t clearly define what makes for a successful coder. It doesn’t explore what scientists do and don’t know about how biological sex shapes behavior. It doesn’t call on experts to debate. It doesn’t evaluate the strengths and weaknesses of the evidence. And it never once discusses what we know about gender discrimination or its long, sordid history in tech. [...] The memo isn’t reaching for a higher truth — it is instead the expression of a reactionary instinct to preserve the status quo. Deflection: now, with graphs!

Why we fell for clean eating
Why has clean eating proved so difficult to kill off? Hadley Freeman, in this paper, identified clean eating as part of a post-truth culture, whose adherents are impervious, or even hostile, to facts and experts. But to understand how clean eating took hold with such tenacity, it’s necessary first to consider just what a terrifying thing food has become for millions of people in the modern world. The interesting question is not whether clean eating is nonsense, but why so many intelligent people decided to put their faith in it.

Biohackers Encoded Malware in a Strand of DNA
A group of researchers from the University of Washington has shown for the first time that it's possible to encode malicious software into physical strands of DNA, so that when a gene sequencer analyzes it the resulting data becomes a program that corrupts gene-sequencing software and takes control of the underlying computer.

Stop Saying Mansplaining Isn’t a Big Deal. It is.
If you, as a man, claim to know more about a woman’s own body than she does, you are mansplaining. When you start to question her own experiences and reality and feelings and opinions just because you don’t like them, you are mansplaining. When you feel that you are better qualified to make choices that influence her autonomy over her own body, you are mansplaining. When you ridicule or dismiss her viewpoints and her description of reality, despite having zero evidence to support the idea that she’s wrong or mistaken, you are mansplaining. And in doing so, you are perpetuating the misogyny and sexism that defines nearly every part of a woman’s existence.

The Fiercely Precise World of Competitive Table-Setting
In addition to creative pressures, tablescapers must also have an encyclopedic knowledge of the lost art of how to set a table. The dishes, glasses and flatware must correspond with the proposed menu, and those items must be laid out perfectly, down to the direction of the knife blade. Mistakes cost competitors points, detracted by anonymous judges whose choices can sometimes feel arbitrary.

Is There a Giant Planet Lurking Beyond Pluto?
As faint as the tiniest moons of Pluto, Planet Nine would be barely two pixels wide on the Hubble Space Telescope’s camera. Searchers could easily miss it among random speckles of sensor noise and the twinkling of distant and variable stars. And because the planet is so far from Earth, near the far end of a highly elliptical path that takes at least 15,000 years to complete, astronomers have to wait a day or more between successive photographs of the right patch of sky to see the planet shift its apparent position relative to the much more distant stars.

Robust Physical-World Attacks on Machine Learning Models
Our algorithm can create spatially- constrained perturbations that mimic vandalism or art to reduce the likelihood of detection by a casual observer. We show that adversarial examples generated by RP2 achieve high success rates under various conditions for real road sign recognition by using an evaluation methodology that captures physical world conditions. We physically realized and evaluated two attacks, one that causes a Stop sign to be misclassified as a Speed Limit sign in 100% of the testing conditions, and one that causes a Right Turn sign to be misclassified as either a Stop or Added Lane sign in 100% of the testing conditions.

The Evolution of Trust
During World War I, peace broke out.

It was Christmas 1914 on the Western Front.
Despite strict orders not to chillax with the enemy, British
and German soldiers left their trenches, crossed No Man's Land,
and gathered to bury their dead, exchange gifts, and play games.

Meanwhile: it's 2017, the West has been at peace for decades, and
wow, we suck at trust. Surveys show that, over the past forty years, fewer and fewer people say they trust each other. So here's our puzzle:

Why, even in peacetime, do friends become enemies?
And why, even in wartime, do enemies become friends?

I think game theory can help explain our epidemic of distrust –
and how we can fix it! So, to understand all this...

Where Did Amoxicillin's Flavor Come From?
Under the humoral theory of medicine, Berenstein says, “tastes themselves were correlated with the body’s humors.” So if someone’s four humors—black bile, yellow bile, blood, and phlegm—were seen to be out of balance, they’d likely be advised to avoid certain tastes, and eat more of others. A melancholic person, for example, might want to avoid vinegar (sour—just like them), and eat more sugar to balance themselves out. “It wasn’t about a spoonful of sugar making the medicine go down,” Berenstein says. “A spoonful of sugar was the medicine.”

For Those Considering Blaxit, I Present to You: Melbourne (Yes, Australia)
Australia exists within a geopolitical vacuum and has one of the most casually accepted cultures of racism I’ve ever experienced. It’s a culture where refugees are held illegally in offshore detention camps, with minimal public outcry. It’s one that puts immigrants and other people in a hierarchy, where Southern Europeans are near the top, followed by Asians, African Americans and then Africans, Arabs and Aborigines (for whom their hatred burns eternal). But even though World War II gave Australia a certain reverence for Americans, including black ones, the fetishism and ignorance around race and diversity make even the most flippant “Hey, Macy Gray!” or “I love black men” comments all the more repugnant.

Program Design by Calculation
This textbook in preparation has arisen from the author’s research and teaching experience. Its main aim is to provide software practitioners with a calculational approach to the design of software artifacts ranging from simple algorithms and functions to the specification and realization of information systems. Put in other words, the book invites software designers to raise standards and adopt mature development techniques found in other engineering disciplines, which (as a rule) are rooted on a sound mathematical basis so as to enable algebraic reasoning.

When you try to actually look at the content (extract or decompress it) then you'll most likely run out of disk space or RAM.

Cassini Finds Saturn Moon May Have Tipped Over
Whether it was caused by an impact or some other process, Tajeddine and colleagues think the disruption and creation of the tiger-stripe terrain caused some of Enceladus' mass to be redistributed, making the moon's rotation unsteady and wobbly. The rotation would have eventually stabilized, likely taking more than a million years. By the time the rotation settled down, the north-south axis would have reoriented to pass through different points on the surface -- a mechanism researchers call "true polar wander."
