This Is Your Mind On Brains (jdargis)
A number of studies have also identified parts of the brain involved in representing concepts, such as the notion of actions or tools. But for the new Nature paper, Alexander Huth, a postdoctoral researcher in the lab of Jack Gallant at the University of California–Berkeley, took a much more comprehensive approach, testing thousands of words, embedded in lengthy narratives, to see what kinds of activation patterns turned up.
SpaceX had landed once successfully at sea a month ago. But that landing attempt after flying a Dragon spacecraft to low-Earth orbit had a favorable flight profile for bringing the rocket back to land—not too great a reentry velocity and plenty of fuel to slow the rocket down. Friday morning’s launch, which ultimately delivered a Japanese communications satellite to a transfer orbit some 35,786km above the Earth, led to extreme reentry speeds and temperatures. Although Elon Musk optimistically tweeted the odds were “maybe even” of success, the company’s official prognosis was “unlikely.”
Yet three large uncertainties plague the original Drake equation. "We've known for a long time approximately how many stars exist,” Frank explained in a statement. “We didn't know how many of those stars had planets that could potentially harbor life, how often life might evolve and lead to intelligent beings, and how long any civilizations might last before becoming extinct… Thanks to NASA's Kepler satellite and other searches, we now know that roughly one-fifth of stars have planets in 'habitable zones,' where temperatures could support life as we know it. So one of the three big uncertainties has now been constrained."
The other thing is, it's pretty common, at least in American society, that in order to have high self-esteem, you have to feel special and above-average. If someone said, "Oh, your performance was average," you would feel hurt by that, almost insulted.
When we fail, self-esteem deserts us, which is precisely when we need it most.
"Boaty" lives on as the name of one of the ship's remotely operated submarines.
But why couldn't the main vessel itself have carried the name? Here's one reason: imagine the ship were to get into trouble at some point in the future.
While all previous charts were interesting and meaningful, the most fascinating chart currently is GOLD. This is an incredible story. The yellow metal moved from the bottom of its descending trend channel to the top in a matter of weeks. That was an extremely powerful move, and we admit in all honesty that we did not see that coming.
According to an article yesterday in The Wall Street Journal, Lyft will give customers the option of riding in the prototype autonomous Bolt EV when they request a ride through its app.
The company didn't name the city in which the pilot program would be conducted.
The Paradox Of Radiation (jdargis)
Today, heavy regulation requires many stages of preclinical testing before treating patients, but Grubbe boldly tried X-rays on a cancer patient just two days later. Rose Lee, who had advanced breast cancer, was desperate. She had two prior surgeries to remove her tumor, but the cancer kept coming back. On referral from one of Grubbe’s professors, Lee sat for a total of 18 X-ray treatments at the light bulb factory. Grubbe simply positioned the Crookes tube over the tumor and turned on the electric current for a few minutes, with little understanding of what would be the appropriate dose. The treatments did reduce her pain. Nevertheless, she died a month later.
