A small pressure leak was discovered on the International Space Station, according to NASA. From a report: Flight controllers at mission control centers in Houston and Moscow began seeing signs of the leak Wednesday night when the six-member crew aboard the orbital outpost were asleep. Flight controllers monitored the situation until the crew awakened at their normal time Thursday morning "since they were in no danger," NASA said in a media release. Crew members then conducted "extensive checks" to determine the location of the leak, which appears to be on the Russian side of the space station. They initially slowed the leak with Kapton tape and are working on a more comprehensive repair, according to NASA. "Program officials and flight controllers are continuing to monitor the situation as the crew works through its troubleshooting procedures," NASA said.

Venezuelan president Nicolas Maduro has made ambitious claims that the nation's petro cryptocurrency is backed by 5 billion barrels of petroleum reserves. But when reporters of Reuters conducted a months-long investigation, they found that petro is getting little to no traction in the nation or elsewhere. Reuters: Located in an isolated savanna in the center of the country, Atapirire is the only town in an area the government says is brimming with 5 billion barrels of petroleum. Venezuela has pledged those reserves as backing for a digital currency dubbed the "petro," which Maduro launched in February. This month he vowed it would be the cornerstone of a recovery plan for the crisis-stricken nation. But Atapirire residents say they have seen no efforts by the government to tap those reserves. And they have little confidence that their struggling village has a front-row seat to a revolution in finance. "There is no sign of that petro here," said homemaker Igdalia Diaz. She launched into a diatribe about her town's crumbling school, pitted roads, frequent blackouts and perpetually hungry citizens.

It turns out that Venezuela's petro is hard to spot almost anywhere. Over a period of four months, Reuters spoke with a dozen experts on cryptocurrencies and oil-field valuation, traveled to the site of the pledged oil reserves and scoured the coin's digital transaction records in an effort to learn more. The hunt turned up little evidence of a thriving petro trade. The coin is not sold on any major cryptocurrency exchange. No shops are known to accept it.

Last month, Google introduced its Titan Key -- a physical security key used for two-factor authentication -- and now it's widely available for purchase in the US through company's Google Store. Almost any modern browser and mobile device, as well as services such as Dropbox, Twitter, Facebook, Salesforce, Stripe support the Titan Key. It's Google's take on a Fast Identity Online key, a physical device used to authenticate logins over Bluetooth. From a report: For $50, you'll get a USB security key and a Bluetooth security key as well as a USB-C to USB-A adapter and a USB-C to USB-A connecting cable. What happens if you lose them? From a report: A downside of physical keys is that if lose them, you're toast. That's why you have two keys -- one is meant to be a backup. Google says it can help you gain access to your account again but the recovery process can take days. VentureBeat adds: It's not meant to compete with other FIDO keys on the market, stressed Sam Srinivas, product management director for information security at Google, during a press pre-briefing. Rather, it's "for customers who want security keys and trust Google," he said. Further reading: None of Google's 85,000 Employees Have Been Phished in More Than a Year After Company Required Them to Use Physical Security Keys For 2FA.

Commuters are so regularly using travel time for work emails that their journeys should be counted as part of the working day, researchers say. From a report: Wider access to wi-fi on trains and the spread of mobile phones has extended the working day, a study from the University of the West of England says. The study examined 5,000 rail passengers on commuter routes into London as wi-fi became more available. "I am a busy mum and I rely on that time," one commuter told researchers. The study, to be presented at the Royal Geographical Society on Thursday, found that 54% of commuters using the train's wi-fi were sending work emails. Others were using their own mobile phone connections for work emails.

An anonymous reader quotes a report from Smithsonian: According to new research, rising carbon dioxide levels will sap some of the nutrients from our crops and lead to dietary deficiencies in millions of humans. In 2014, field trials of common food crops including wheat, rice, corn and soybeans showed that as the amount of carbon dioxide in the atmosphere increased, the levels of iron, zinc and protein decreased in the dietary staples by 3 to 17 percent. While the decrease in a few nutrients may not seem important in food secure countries, it could have a big impact in poorer nations.

In the new study published in the journal Nature Climate Change, researchers calculated the impact of declining nutrients on human health. According to a press release, the team looked at the impact of rising CO2 on 225 different types of food. Based on population estimates for 2050 and an expected rise of carbon dioxide from about 400 parts per million today to 550 ppm by mid-century, the team found that the nutrient deficiencies of those already suffering will worsen, and 175 million more people could join the 1.2 billion who are zinc deficient and 122 million people would be added to the 622 million who don't receive enough protein. About 1.4 billion women of childbearing age and children under 5 could see their iron intake drop by about 4 percent.

Following a string of murders by drivers of China's top ridesharing app, Didi Chuxing, users are deleting the app in large numbers and calling for others to boycott the service. According to The Atlantic, "the hashtag #BoycottDidi on Weibo has garnered more than 1 million views." From the report: Over the weekend, the driver confessed to local police to raping and stabbing his 20-year-old passenger on her way to a friend's birthday party. The murder is the second in three months -- this May, a young flight attendant was killed by her Didi driver. It is the third in a year -- last May, according to Caixin Global, another woman was strangled and killed by her driver. And it is the fourth in two years -- the year before that, a female teacher was robbed and killed after threats from her driver.

"As a platform, we have disappointed the public's trust in us and cannot shirk this responsibility," Didi said in a statement, admitting to failing to react quickly to another passenger's complaint filed against the driver the day before the murder. The rideshare company has suspended its Hitch services (as it did after the last murder) and fired two senior executives, one in charge of Hitch, its intercity carpooling service, and the other in charge of customer service. The Didi president, Jean Liu, oft-regarded as a hero for Chinese women in business, issued an apology on Tuesday. China's government is now cracking down on reform across the transportation sector.

Eric Berger writes via Ars Technica: The Apollo missions that flew to the Moon during the 1960s were designed and controlled by what is now known as Johnson Space Center, the home of the famous "Mission Control." Moreover, the astronauts that flew to the Moon all lived in Houston. It would stand to reason, therefore, that as NASA gears up to return to the Moon, major elements of this program would likewise be controlled from the Texas metropolis that styles itself "Space City." Times change, however. In recent months, the politically well-positioned Marshall Space Flight Center, in Huntsville, Alabama, has been quietly pressing leaders with NASA Headquarters for program management of mid- to large-size landers to the lunar surface, which would evolve into human landers. Sources indicated this effort was having some success.

However, Texas legislators have now begun to push back. On Tuesday, both of Texas' senators (John Cornyn and Ted Cruz), as well as three representatives with space-related committee chairs (John Culberson, Lamar Smith, and Brian Babin), wrote a letter to NASA Administrator Jim Bridenstine. "We support NASA's focus on returning to the Moon and using it as part of a stepping stone approach to place American boots on the surface of Mars in the 2030s," the Texas Republicans wrote. "As NASA reviews solicitations for lunar landers, we write to express our strong support for the establishment of NASA's lunar lander program at the Johnson Space Center." The letter reminds Bridenstine of Houston's strong spaceflight heritage.

An anonymous reader quotes a report from The Verge: President Donald Trump intensified his criticism of Google today, posting a native video of unknown origin to his Twitter account this afternoon claiming the search giant stopped promoting the State of the Union (SOTU) address on its homepage after he took office. It turns out the video he posted is not only misleading, but also contains what appears to be a fake screenshot of the Google homepage on the day in question. It has since been viewed more than 1.5 million times. In a statement given to The Verge, a Google spokesperson clarifies that the company promoted neither former President Barack Obama nor Trump's inaugural SOTU addresses in 2009 and 2017, respectively. That's because they were not technically State of the Union addresses, but "addresses to a joint session" of Congress, a tradition set back in 1993 so that new presidents didn't have to immediately deliver SOTU addresses after holding office for just a few weeks. Google resumed promoting Obama's SOTU address in 2010 and continued to do so through 2016, as he held office for all six of those years.

With regards to the 2018 SOTU, Google says it did in fact promote it on its homepage. "On January 30th 2018, we highlighted the livestream of President Trump's State of the Union on the google.com homepage," reads Google's statement. "We have historically not promoted the first address to Congress by a new President, which is not a State of the Union address. As a result, we didn't include a promotion on google.com for this address in either 2009 or 2017."

dmoberhaus writes: Yesterday, a writer for SB Nation named Natalie Weiner posted a screenshot of a rejection form she received when she tried to sign up for a website. Her submission was rejected because a spam algorithm considered her last name "offensive." After she posted about this, hundreds of other people with similarly "offensive" last names sounded off about how they had experienced similar issues. As it turns out, this phenomenon is so widespread that it has a name among computer scientists. It's called the Scunthorpe problem and it's been a scourge of the internet since the beginning. Motherboard spoke to content moderation experts about its origins and why it's such a hard problem to solve 20 years later. A big reason why the problem has yet to be solved is "because creating effective obscenity filters depends on the filter's ability to understand a word in context," reports Motherboard. "Despite advances in [AI], this is something that even the most advanced machine-learning algorithms still struggle with today."

"This works both ways around," Michael Veale, a researcher studying responsible machine learning at University College London, told Motherboard. "Cock (a bird) and Dick (the given name) are both harmless in certain contexts, even in children's settings online, but in other cases parents might not want them used. Equally, those wanting to abuse a system can find ways around it."

More than a dozen people who work near Waymo's office in Chandler, Arizona, have complained about the self-driving cars to The Information. "One women said that she almost hit one of the company's minivans because it suddenly stopped while trying to make a right turn, while another man said that he gets so frustrated waiting for the cars to cross the intersection that he has illegally driven around them," reports CNBC. From the report: The anecdotes highlight how challenging it can be for self-driving cars, which are programmed to drive conservatively, to master situations that human drivers can handle with relative ease -- like merging or finding a gap in traffic to make a turn. Waymo has been testing its vehicles in the Phoenix suburbs for little more than a year and is widely seen as the furthest along in the self-driving car space, but its safety drivers have to take control of the vehicles regularly, people with direct knowledge of the issues tell The Information.

A Waymo spokesperson said its cars are "continually learning" and that "safety remains its highest priority" during testing. The spokesperson also said that Waymo is using feedback from its early rider program to improve its technology, though it declined to comment specifically on the intersection complaints mentioned in The Information story. The company has previously said that it plans to launch a commercial self-driving taxi service before the end of the year, but that its service will still include a Waymo employee in each car as a "chaperone."

On November 12th, WhatsApp users on Android will be able to back up their messages to Google Drive for free and it won't count towards Google Drive storage quotas. But, as WhatsApp warns, those messages will no longer be protected by end-to-end encryption. ZDNet reports: While Apple iOS users may elect to use iCloud backup storage options, Android users store theirs through Google Drive -- but alongside the changes, WhatsApp has reminded users that once communication, chat, and media is transferred away from the app, end-to-end encryption is no longer in place.

Some users may think that backup services will have the same level of protection as the app. However, this is not the case and the reminder is important for those interested in protecting their privacy. In WhatsApp support documents, this separation is now explicitly mentioned. "Media and messages you back up aren't protected by WhatsApp end-to-end encryption while in Google Drive," WhatsApp says.

An anonymous reader quotes a report from Nature: An experiment at CERN has demonstrated a new way of accelerating electrons to high energies -- one that could dramatically shrink the size of future particle accelerators and lower their costs. The technique is the latest entrant in a hot race to develop a technology called plasma wakefield acceleration. The method uses waves in plasma, a soup of ionized atoms, to push electrons to ever-higher energies over distances much shorter than those required in today's particle accelerators. Several laboratories have demonstrated plasma wakefield acceleration using two different approaches; most teams use laser beams to create the plasma waves needed. The latest work is the first to show that protons can also induce the waves and achieve electron acceleration -- a technique that may have advantages over the others because protons can carry high energies over long distances.

In this case, researchers diverted protons that would usually be fed into the Large Hadron Collider (LHC) at CERN, Europe's particle-physics lab near Geneva, Switzerland, and instead inserted them into the wakefield accelerator, called the Advanced Wakefield Experiment (AWAKE). The machine worked as expected and created a consistent beam of accelerated electrons. "That, for us, was a major achievement," says Matthew Wing, a physicist at University College London, who is deputy spokesperson for AWAKE. "It essentially says that the method works, and it's never been done before." The work is described in Nature on 29 August.

Google is bringing a new user interface to Wear OS, along with a new feed of information from Google Assistant, faster access to Google Fit, and a more information-dense view of your notifications. The Verge examines all these new changes one by one: The most important change is the one you see above: a feed of information from Google Assistant. It's designed to show you relevant info about your day, like calendar details, package-tracking info, and the weather. Next are notifications, which operate basically the same as before. They still mostly mirror what's on your phone. Dismissing a notification on your watch will do the same on your phone, and many apps will allow you to quick reply with suggested chips. But the best feature here is that Google is going back to a more information-dense display that puts all your notifications on a single, scrollable pane instead of having them fill the entire screen one by one.

Swiping left will now take you to the new Google Fit interface, which shows the two new rings that Google is has created to track your health. One is "move minutes" and the other is "heart points." Last but not least, swiping down takes you to a slightly revamped Quick Settings pane, which adds two oft-requested buttons: one for finding your phone and another for Google Pay. More (but perhaps not enough) Wear OS watches come with NFC now, and the Google Pay button will make sure that the chip is on and ready to pay when you walk up to the point-of-sale terminal.

Air Canada told customers in an email today that the personal information for about 20,000 customers "may potentially have been improperly accessed" via a breach in its mobile app. As a precaution, the airline locked down all 1.7 million accounts until customers change their passwords. CBC.ca reports: The app stores basic information such as a user's name, email address and telephone number, all of which could have been improperly accessed. Any credit card information on file would have been encrypted and as such protected, the company says. But additional data such as a customer's Aeroplan number, passport number, Nexus number, known traveller number, gender, birth date, nationality, passport expiration date, passport country of issuance and country of residence could have been accessed, if users had them saved in their profile on the app. Air Canada said it hasn't detected any improper log-in activity since last Friday, and it is in the process of contacting the 20,000 people directly affected.

A misconfigured MongoDB server belonging to Abbyy, an optical character recognition software developer, allowed public access to customer files. From a report: Independent security researcher Bob Diachenko discovered the database on August 19 hosted on the Amazon Web Services (AWS) cloud platform. It was 142GB in size and it allowed access without the need to log in. The sizeable database included scanned documents of the sensitive kind: contracts, non-disclosure agreements, internal letters, and memos. Included were more than 200,000 files from Abbyy customers who scanned the data and kept it at the ready in the cloud. "Some collection names like 'documentRecognition,' or 'documentXML' hinted that database would be part of a data recognition company infrastructure," Diachenko writes in a blog post today.
