The studies, which were collected in the journal Science (pay wall) in January, were conducted over 10 years by team of researchers at Columbia, the University of Southern California, and the University of California, San Diego. The biggest impact of air pollution was measured in farm workers in California's Central Valley, who were paid by the volume of grapes and blueberries they collected. On days that had higher readings of ground-level ozone -- a harmful gas formed when tailpipe emissions mix with sunlight -- worker productivity slumped.
Over the two years they measured the ozone, readings ranged from 10 to 86 parts per billion, and averaged 48 ppb. For every 10 ppb increase in ozone, worker productivity fell 5.5%. For farm workers paid about $9 or $10 an hour, the lost productivity translates into about 45 cents an hour of lower pay, said Matthew Neidell, an economist at Columbia and an author of the studies.
The researchers said they used methods including dual learning for fact-checking translations; deliberation networks, to repeat translations and refine them; and new techniques like joint training, to iteratively boost English-to-Chinese and Chinese-to-English translation systems; and agreement regularization, which can generate translations by reading sentences both left-to-right and right-to-left. Zhou said the techniques used to achieve the milestone won't be limited to machine translations. The researchers caution the system has not yet been tested on real-time news stories, and there are other challenges that still lie ahead before the technology could be commercialized into Microsoft's products. You can play around with the new translation system here.
Wednesday's announcement marks the first criminal charge brought in one of the largest data breaches in history. Ying, the former chief information officer for Equifax's U.S. information-solutions business, used confidential information entrusted to him by the company to determine it had been hacked, according to a separate complaint filed by the Securities and Exchange Commission.
ZDNet adds: According to a Justice Department statement, Ying sent a text message to a colleague two weeks before Equifax revealed the hack, in which he said the breach "sounds bad." Three days later, Ying searched the web to research the effect of Experian's 2015 own breach on its stock price. Later that day, Ying excised all his available stock options.
But his cultural status -- amplified by his disability and the media storm it invoked -- often overshadowed his scientific legacy. That's a shame for the man who discovered what might prove to be the key clue to the theory of everything, advanced our understanding of space and time, helped shape the course of physics for the last four decades and whose insight continues to drive progress in fundamental physics today. The New York Times: 1970 Dr. Hawking shows that the area of a black hole's event horizon -- a spherical surface marking the point of no return -- can only increase, never decrease, as stuff falls into a black hole or it collides and merges with other black holes.
1971 He suggests that mini black holes much smaller than stars created in the Big Bang could be peppering the universe.
1974 He shocks his colleagues and the world by showing that black holes will leak and explode when quantum effects -- the weird laws that describe subatomic behavior -- are taken into account.
1976 Dr. Hawking says exploding black holes add randomness and unpredictability to the universe, forever erasing information about what might have fallen into a black hole.
Quantum physicists object, saying the universe can't forget, initiating a 40-year argument about the fate of information. Dr. Hawking concedes in 2004, but does not say how information is preserved in a black hole, and the argument continues to this day.
1982 Using a mathematical conceit called imaginary time, Dr. Hawking and James Hartle, a theoretical physicist at the University of California, Santa Barbara, propose a model of a self-contained universe that has no boundary in space or time, and thus no place or time when the laws of physics break down.

In the wake of a public reckoning with Facebook's unparalleled ability to distribute information and global anxiety over election meddling, bragging about the company's ability to run highly effective influence campaigns probably doesn't look so great. Facebook's "success stories" page is a monument to the company's dominance of online advertising, providing examples from almost every imaginable industry of how use of the social network gave certain players an advantage. "Case studies like these inspire and motivate us," the page crows.
The company and Elizabeth Holmes have already agreed to settle the charges leveled against them by the SEC. Holmes will have to pay a $500,000 fine and return 18.9 million shares in Theranos that she owned, as well as downgrading her super-majority equity into common stock. The CEO is now barred from serving as the officer or director of a public company for 10 years. In addition, if Theranos is liquidated or acquired, Holmes cannot profit from her remaining shareholding unless $750 million is handed back to defrauded investors. Balwani, on the other hand, is facing a federal court case in the Northern District of California where the SEC will litigate its claims against him. Worth noting: the court still has to approve the deals between Holmes and Theranos, and neither party has admitted any wrongdoing.
The Project explains, "GNOME 3.28 comes with more beautiful things! First, and most significantly, GNOME's default interface font (called Cantarell) has undergone a significant update. Character forms and spacing have been evolved, so that text is more readable and attractive. Several new weights have also been added -- light and extra bold -- which are being used to produce interfaces that are both modern and beautiful. Other beautiful things include GNOME's collection of background wallpapers, which has been updated to include a lovely set of photographs, and the selection of profile pictures, which has been completely updated with attractive new images to pick from."
Unfortunately, you can't just click on a button and upgrade to GNOME 3.28 today. Actually, for the most part, you will need to wait for it to become available for your operating system. Sadly, this can take a while. Fedora users, for instance, will have to wait for a major OS upgrade for it to become available.
"It is probably the most competitive market in the last 20 years that I have been doing this," said Desikan Madhavanur, chief development officer at Scottsdale, Arizona-based JDA Software, whose products help companies manage supply chains. "We have to compete better to get our fair share." What's happening in the market for software engineers may help illustrate why one of the tightest American labor markets in decades isn't leading to broader wage gains. While technology firms are looking at compensation, they are also finding ways to create the supply of workers themselves, which helps hold costs down.
Today's study focuses on the Arctic as the main culprit for the extreme winter weather. Previous research has suggested that the warming Arctic may disrupt the polar vortex, a ring of swirling cold air circling the North Pole. Think of the polar vortex as a river, says study co-author Judah Cohen, a climatologist and director of seasonal forecasting at Atmospheric and Environmental Research. The fast flow of this river locks up the cold air over the Arctic. But as the Arctic warms -- especially in some areas like the Barents-Kara seas north of Europe and Russia -- a boulder springs up in this river, disrupting the polar vortex and allowing the freezing Arctic air to flow south, Cohen says.
The first four characters are the area code, describing a region of roughly 100 x 100 kilometers. The last six characters are the local code, describing the neighborhood and the building, an area of roughly 14 x 14 meters -- about the size of one half of a basketball court. The area code is not needed when navigating within a town, while another optional character can be appended to provide additional accuracy down to a 3 x 3 meter region. Users of Google Maps in India will be able to easily find the plus code for any area in the app, while the mapping service along with Search will support the entry of the new coordinate system. Plus codes for any location can also be found with this tool.
The 2014 film about his life, "The Theory of Everything," was nominated for several Academy Awards and Eddie Redmayne, who played Dr. Hawking, won the best-actor Oscar. Scientifically, Dr. Hawking will be best remembered for a discovery so strange that it might be expressed in the form of a Zen koan: When is a black hole not black? When it explodes. A brief history of Stephen Hawking: A legacy of paradox.
