An ignored 1968 US govt report: racism & inequality are drivers of urban violence
In response to unrest and riots in urban areas across the US in the mid-to-late 1960s, President Lyndon Johnson formed a commission to find out why it was happening. As Ariel Aberg-Riger’s illustrated piece relates, the resulting report, the Report of the National Advisory Commission on Civil Disorders (more commonly known as the Kerner Report), was blunt in its conclusions: “Our Nation is moving toward two societies, one black, one white — separate and unequal.”

A mosquito in a nudist colony
President Donald Trump and Republicans in Congress rolled back a gun regulation last year that would have restricted some people with mental disabilities from buying guns. Now, this story isn’t about gun control, but the law they used to erase that rule and 14 others last year. It’s a tale that goes back decades, and it starts in Kenya in the 1960s. Along the way, we’ll meet a man in a white suit and an army of used car dealers.

Measuring Unintended Neural Network Memorization & Extracting Secrets
This paper presents exposure, a simple-to-compute metric that can be applied to any deep learning model for measuring the memorization of secrets. Using this metric, we show how to extract those secrets efficiently using black-box API access. Further, we show that unintended memorization occurs early, is not due to overfitting, and is a persistent issue across different types of models, hyperparameters, and training strategies.

David Swenson's electrostatic 'invisible wall'
David Swenson of 3M Corporation describes an anomaly where workers encountered a strange "invisible wall" in the area under a fast-moving sheet of electrically charged polypropelene film in a factory. This "invisible wall" was strong enough to prevent humans from passing through. A person near this "wall" was unable to turn, and so had to walk backwards to retreat from it.

Justice, Interrupted: The Effect of Gender, Ideology and Seniority at Supreme Court Oral Arguments by Tonja Jacobi, Dylan Schweers :: SSRN
We find that judicial interactions at oral argument are highly gendered, with women being interrupted at disproportionate rates by their male colleagues, as well as by male advocates. Oral argument interruptions are also highly ideological, not only because ideological foes interrupt each other far more than ideological allies do, but we show that conservatives interrupt liberals more frequently than vice versa.

How you can be tracked even with your GPS turned off
This new tracking method comes from researchers at Princeton University. The team was able to create an app to detect information from sensors that it doesn’t need special permission to access. The trick in accurately tracking a person with this method is finding out what kind of activity they’re performing. Whether they’re walking, driving a car, or riding in a train or airplane, it’s pretty easy to figure out when you know what you’re looking for.

The sentence that helped set off the opioid crisis
When OxyContin went to market in 1996, sales reps from Purdue Pharma hit one point particularly hard: Compared to other prescription opioids, this new painkiller was believed to be less likely to be addictive or abused. But recently unsealed documents in this investigative episode shed light on how the maker of OxyContin seems to have relied more on focus groups than on scientific studies to create an aggressive and misleading marketing campaign that helped fuel the national opioid crisis.

Doug Engelbart 1968 Demo
On December 9, 1968, Douglas C. Engelbart and the group of 17 researchers working with him in the Augmentation Research Center at Stanford Research Institute in Menlo Park, CA, presented a 90-minute live public demonstration of the online system, NLS, they had been working on since 1962. The public presentation was a session of the Fall Joint Computer Conference held at the Convention Center in San Francisco, and it was attended by about 1,000 computer professionals. This was the public debut of the computer mouse. But the mouse was only one of many innovations demonstrated that day, including hypertext, object addressing and dynamic file linking, as well as shared-screen collaboration  involving two persons at different sites communicating over a network with audio and video interface.

Ruth Bader Ginsburg set out to convince an all-male Supreme Court to take sex discrimination seriously
“Equal protection of the laws” was granted to all persons by the 14th Amendment in 1868. But for nearly a century after that, women had a hard time convincing the courts that they should be allowed to be jurors, lawyers, and bartenders, just the same as men. A then-lawyer at the ACLU named Ruth Bader Ginsburg set out to convince an all-male Supreme Court to take sex discrimination seriously with an unconventional strategy. She didn’t just bring cases where women were the victims of discrimination; she also brought cases where men were the victims. In this episode, we look at how a key battle for gender equality was won with frat boys and beer.

Mathematicians Measure Infinities, Find They’re Equal
In a breakthrough that disproves decades of conventional wisdom, two mathematicians have shown that two different variants of infinity are actually the same size. The advance touches on one of the most famous and intractable problems in mathematics: whether there exist infinities between the infinite size of the natural numbers and the larger infinite size of the real numbers.

To say that it’s little known that key crops are getting less nutritious due to rising CO2 is an understatement. Across nearly 130 varieties of plants and more than 15,000 samples collected from experiments over the past three decades, the overall concentration of minerals like calcium, magnesium, potassium, zinc and iron had dropped by 8 percent on average. The ratio of carbohydrates to minerals was going up. The plants, like the algae, were becoming junk food.

JavaScript is for Girls
The traits of a “good programmer” differed by country, but they were universally male-gendered, enforced by hiring managers and other programmers who sought to replicate their own characteristics—not consciously, for the most part, but simply because the jobs were important.

Hicks, the computing historian, can’t stand it when people tout coding camps as a solution to technology’s gender problem. “I think these initiatives are well-meaning, but they totally misunderstand the problem. The pipeline is not the problem; the meritocracy is the problem. The idea that we’ll just stuff people into the pipeline assumes a meritocracy that does not exist.”

Birds on Islands Are Losing the Ability to Fly
Flight muscles come with a cost. Even at rest, larger ones require more energy to maintain. So if birds can get away with smaller ones, evolution pushes them in that direction. Large flight muscles are especially useful when birds take off. That’s the most energetically demanding part of flying, and the bit that’s most important for escaping from ground predators. If such predators are absent, birds can take off at a more leisurely pace, and they can afford to have smaller (and cheaper) flight muscles.

The booby-trapped screens also exploited operating system vulnerabilities that bypassed key security protections built into the phones. The malicious parts cost less than $10 and could easily be mass-produced. Most chilling of all, to most people, the booby-trapped parts could be indistinguishable from legitimate ones, a trait that could leave many service technicians unaware of the maliciousness. There would be no sign of tampering unless someone with a background in hardware disassembled the repaired phone and inspected it.

Using chatbots against voicespam: analyzing Lenny’s effectiveness
Without any AI or speech recognition mechanism instead relying entirely on a set of 16 pre-recorded responses, Lenny is able to trick many people and keep conversations going for many minutes, and in one case up to an hour! Spammers on average spend 10:13 minutes talking to Lenny, and these conversations have an average of 58 turns! On average, a caller hears 27 turns of Lenny, which corresponds to 1.7x repetition of the whole script. Surprisingly, in only 11 calls (5%), the caller realizes and states that he is talking to a recording or an automated system.

Automatic detection and decoding of honey bee waggle dances
The waggle dance is one of the most popular examples of animal communication. Forager bees direct their nestmates to profitable resources via a complex motor display. Essentially, the dance encodes the polar coordinates to the resource in the field. Unemployed foragers follow the dancer’s movements and then search for the advertised spots in the field. Throughout the last decades, biologists have employed different techniques to measure key characteristics of the waggle dance and decode the information that it conveys. Early techniques involved the use of protractors and stopwatches to measure the dance orientation and duration directly from the observation hive. Recent approaches employ digital video recordings from which dance characteristics are extracted using digital protractors on screen. However, manual approaches are very time-consuming. Most studies, therefore, regard only small numbers of animals in short periods of time. We have developed a system capable of automatically detecting, decoding and mapping communication dances in real-time.

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!

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.

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.

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.

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

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.

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."
