Here's another quick item I can take six minutes to post while still in article-deadline-hell mode. It's a warning, from a computer-security conference in Amsterdam, that hackers equipped merely with Android phones could remotely take control of an airliner and guide it in all sorts of unwelcome ways, including right into another plane. As in the classic pilot-world joke photoshopped item above.
Once [the hacker with an Android] was into the airplane's computer, he was able to manipulate the steering of a Boeing jet while the aircraft was in "autopilot" mode. The only countermeasure available to pilots, if they even realized they were being hacked, would be to turn off autopilot. Yet many planes no longer have old analog instruments for manual flying.
Two words: Unt. Uh.
Let's set aside the "if" of whether pilots would notice that the plane was going where it shouldn't. True, there have been cases of flight crews losing attention while talking or even dozing off en route. But most flight crews most of the time are tracking the plane's progress along a series of waypoints, and talking to air traffic controllers about where they're going and why.
Instead, these two issues:
1) You don't need instruments to control a plane. That is like saying you need a speedometer to drive a car. Obviously you want all the info you can get, and in an airplane the airspeed gauge in particular is very important (mainly in gauging proper speeds for approach and landing, in flap deployment, and in avoiding aerodynamic stalls). But even basic pilot training includes drills in how to control the plane if instruments fail. There's a special case we can set aside for the moment: the difficulty of controlling the plane if you are inside a cloud and lose the instruments that keep you oriented.
2) Every non-drone airplane flying anywhere in the sky is equipped for "manual flying." That is how they all get off the ground, with some pilot applying the power, pulling back on the control wheel/stick, and managing the "rotation" as the plane lifts off from the runway. This is how planes usually land. Every single airplane -- every one -- is equipped with systems to allow the pilot to bring it back to earth if all the automated wizardry fails. Every pilot is made to practice these emergency measures. Again to put it in automotive terms: imagining that you could not fly the plane if you turned off the autopilot is exactly like saying that you could not drive a car if you turned off cruise-control.
The Android-hacking scenario might apply to drones -- I don't know enough about the override abilities the ground-based human pilots have. (After all, the controller and the hacker would both be sending commands remotely.) But I can tell you that no one with an Android phone is going to make it impossible for a pilot to land any of today's real planes.

Today’s empires are born on the web, and exert tremendous power in the material world.
Mark Zuckerberg hasn’t had the best week.
First, Facebook’s Free Basics platform was effectively banned in India. Then, a high-profile member of Facebook’s board of directors, the venture capitalist Marc Andreessen, sounded off about the decision to his nearly half-a-million Twitter followers with a stunning comment.
“Anti-colonialism has been economically catastrophic for the Indian people for decades,” Andreessen wrote. “Why stop now?”
After that, the Internet went nuts.
Andreessen deleted his tweet, apologized, and underscored that he is “100 percent opposed to colonialism” and “100 percent in favor of independence and freedom.” Zuckerberg, Facebook’s CEO, followed up with his own Facebook post to say Andreessen’s comment was “deeply upsetting” to him, and not representative of the way he thinks “at all.”
Why the Syrian war—and the future of Europe—may hinge on one city
This week, the Syrian army, backed by Russian air strikes and Iranian-supported militias including Hezbollah, launched a major offensive to encircle rebel strongholds in the northern city of Aleppo, choking off one of the last two secure routes connecting the city to Turkey and closing in on the second. This would cut supplies not only to a core of the rebellion against Syrian President Bashar al-Assad, but also to the city’s 300,000 remaining civilians, who may soon find themselves besieged like hundreds of thousands of others in the country. In response, 50,000 civilians have fled Aleppo for the Turkish border, where the border crossing is currently closed. An unnamed U.S. defense official toldThe Daily Beast’s Nancy Youssef that “the war is essentially over” if Assad manages to seize and hold Aleppo.
By announcing the first detection of gravitational waves, scientists have vindicated Einstein and given humans a new way to look at the universe.
More than a billion years ago, in a galaxy that sits more than a billion light-years away, two black holes spiraled together and collided. We can’t see this collision, but we know it happened because, as Albert Einstein predicted a century ago, gravitational waves rippled out from it and traveled across the universe to an ultra-sensitive detector here on Earth.
This discovery, announced today by researchers with the Laser Interferometer Gravitational-wave Observatory (LIGO), marks another triumph for Einstein’s general theory of relativity. And more importantly, it marks the beginning of a new era in the study of the universe: the advent of gravitational-wave astronomy. The universe has just become a much more interesting place.
By mining electronic medical records, scientists show the lasting legacy of prehistoric sex on modern humans’ health.
Modern humans originated in Africa, and started spreading around the world about 60,000 years ago. As they entered Asia and Europe, they encountered other groups of ancient humans that had already settled in these regions, such as Neanderthals. And sometimes, when these groups met, they had sex.
We know about these prehistoric liaisons because they left permanent marks on our genome. Even though Neanderthals are now extinct, every living person outside of Africa can trace between 1 and 5 percent of our DNA back to them. (I am 2.6 percent Neanderthal, if you were wondering, which pales in comparison to my colleague James Fallows at 5 percent.)
This lasting legacy was revealed in 2010 when the complete Neanderthal genome was published. Since then, researchers have been trying to figure out what, if anything, the Neanderthal sequences are doing in our own genome. Are they just passive hitchhikers, or did they bestow important adaptations on early humans? And are they affecting the health of modern ones?
Once it was because they weren’t as well educated. What’s holding them back now?
Though headway has been made in bringing women’s wages more in line with men’s in the past several decades, that convergence seems to have stalled in more recent years. To help determine why, Francine D. Blau and Lawrence M. Kahn, the authors of a new study from the National Bureau of Economic Research parse data on wages and occupations from 1980 to 2010. They find that as more women attended and graduated college and headed into the working world, education and professional experience levels stopped playing a significant role in the the difference between men and women’s wages. Whatever remains of the discrepancy can’t be explained by women not having basic skills and credentials. So what does explain it?
The number of American teens who excel at advanced math has surged. Why?
On a sultry evening last July, a tall, soft-spoken 17-year-old named David Stoner and nearly 600 other math whizzes from all over the world sat huddled in small groups around wicker bistro tables, talking in low voices and obsessively refreshing the browsers on their laptops. The air in the cavernous lobby of the Lotus Hotel Pang Suan Kaew in Chiang Mai, Thailand, was humid, recalls Stoner, whose light South Carolina accent warms his carefully chosen words. The tension in the room made it seem especially heavy, like the atmosphere at a high-stakes poker tournament.
Stoner and five teammates were representing the United States in the 56th International Mathematical Olympiad. They figured they’d done pretty well over the two days of competition. God knows, they’d trained hard. Stoner, like his teammates, had endured a grueling regime for more than a year—practicing tricky problems over breakfast before school and taking on more problems late into the evening after he completed the homework for his college-level math classes. Sometimes, he sketched out proofs on the large dry-erase board his dad had installed in his bedroom. Most nights, he put himself to sleep reading books like New Problems in Euclidean Geometry and An Introduction to Diophantine Equations.
When four American women were murdered during El Salvador’s dirty war, a young U.S. official and his unlikely partner risked their lives to solve the case.
On December 1, 1980, two American Catholic churchwomen—an Ursuline nun and a lay missionary—sat down to dinner with Robert White, the U.S. ambassador to El Salvador. They worked in rural areas ministering to El Salvador’s desperately impoverished peasants, and White admired their commitment and courage. The talk turned to the government’s brutal tactics for fighting the country’s left-wing guerrillas, in a dirty war waged by death squads that dumped bodies in the streets and an army that massacred civilians. The women were alarmed by the incoming Reagan administration’s plans for a closer relationship with the military-led government. Because of a curfew, the women spent the night at the ambassador’s residence. The next day, after breakfast with the ambassador’s wife, they drove to San Salvador’s international airport to pick up two colleagues who were flying back from a conference in Nicaragua. Within hours, all four women would be dead.
If Bernie Sanders is serious about a political transformation in America, he needs a better plan.
If there’s one thing that fires up Bernie Sanders supporters—and makes his detractors roll their eyes—it’s his call for a “political revolution.” To his base, it’s the very point of his anti-establishment, anti-elite candidacy. To his critics, it’s the very embodiment of his campaign’s naïve impracticality and vagueness.
But now that voters in Iowa and New Hampshire have spoken, it’s time to take the idea of political revolution more seriously—more seriously, indeed, than Sanders himself appears to have. It’s time to ask: What exactly would it take?
It starts with Congress. And here it’s instructive to compare Sanders and Donald Trump. Both rely on broad, satisfying refrains of “We’re gonna”: We’re gonna break up the big banks. We’re gonna make Mexico build the wall. We’re gonna end the rule of Wall Street billionaires. We’re gonna make China stop ripping us off.
When two black holes collide, the noises scientists hear are birdlike.
This morning, scientists from the Laser Interferometer Gravity Observatory announced that LIGO had detected gravitational waves from the collision of two black holes, an event so cataclysmic that it converted the mass of three solar systems into pure energy in about a tenth of a second.
Scientists have been trying to figure out how to “listen” to gravitational waves—and to prove their existence—ever since Einstein predicted them in 1915. But until September 14, 2015, when the colliding black-hole event was first detected, this was beyond our technical abilities. In the words of Scott Hughes, “Gravity is a weak force. Measuring these things is bloody hard.”
Hughes is a theoretical physicist at MIT who has been contemplating LIGO since its inception in 1992. He has struggled with a question at the heart of the observatory program: Once we do hear gravitational waves, how will we know where they come from? How can we use them to explore the mysteries of the cosmos? To this end, Hughes has modeled the “sounds” of a host of astrophysical events, including colliding black holes. (You can listen to his impressions of these sounds below.)
