Purell’s marketing might need something like this.

The maker of Purell hand sanitizers is washing away some unproven marketing claims that its products reduce school absenteeism and prevent infections from germs such as Ebola, norovirus, flu, and certain drug-resistant infections.

The marketing disinfection comes after the Food and Drug Administration issued

a warning letter

to Purell’s parent company, GOJO Industries. The letter, dated January 17 and released this week, stated that the company’s claims violated federal regulations and that the agency now considers Purell hand sanitizers unapproved new drugs.

The FDA also noted that it is “unaware of any adequate and well-controlled clinical trials in the published literature that support” GOJO’s claims.

The agency noted that the dubious marketing claims appeared in a variety of places on GOJO’s product websites, including FAQ pages, blogs, and social media pages. Among the questionable claims are that Purell sanitizer:

  • “kills more than 99.99% of most common germs that may cause illness in a healthcare setting, including MRSA [methicillin-resistant Staphylococcus aureus] & VRE [vancomycin-resistant enterococci]”
  • “can reduce student absenteeism by up to 51%… Additionally, teachers who follow this program also experience a 10% reduction of absenteeism.”
  • “may be effective against viruses such as the Ebola virus, norovirus, and influenza.”

While alcohol-based sanitizers have been shown to effectively kill many germs, that finding is different from data indicating that sanitizer use reduces infections and the spread of disease.

On an FAQ page, GOJO also says that “the World Health Organization (WHO) and the Center for Disease Control and Prevention (CDC) are recommending the use of alcohol-based hand sanitizer as a preventive measure for flu prevention.”

But it should be noted that the WHO and the CDC emphasize hand washing as a primary method to prevent the spread of influenza (aside from vaccination). The CDC only recommends using hand sanitizer “if soap and water are not available.” Some data suggests that hand washing is more effective at preventing spread of the flu than using sanitizers. And a study in 2018 suggested that certain bacteria may develop tolerance to alcohol-based sanitizers over time.

In a statement, GOJO’s corporate communications senior director, Samantha Williams, said:

GOJO took immediate action to respond to FDA claim requirements after receiving a warning letter from the agency on January 17. The letter was related to some of our marketing around Purell Hand Sanitizer on GOJO.com and through our social media platforms.

It is important to emphasize that the FDA letter was not related to the safety or quality of our products, or our manufacturing processes.

Some of the problematic statements on GOJO’s sites have since been removed, though the company still says that the WHO and CDC recommends hand sanitizer without mentioning hand washing. Williams’ statement went on to say that GOJO has “begun updating relevant website and other digital content as directed by the FDA and are taking steps to prevent a recurrence.”

Copy and paste seamlessly across all your devices

https://www.popsci.com/story/diy/copy-paste-across-devices/

You probably know how to sync your files—now learn how to sync your clipboards.

Many of us juggle more than one device during the day—phone, laptop, tablet, and sometimes even secondary phones and smartwatches. But you might have wondered if, and how, you can move text and images from one to the other. It can get really crazy, really fast.

Apple, Google, and Microsoft know this, too, which is why they’re making it easier to send data from one device to another—as long as they are connected to the same accounts.

Apple: iOS, iPadOS, and macOS

Apple's Universal Clipboard works over a Bluetooth connection, so make sure you have that on before you try to copy and paste content across devices.

If you’re sending text and images between Apple devices, a feature called the Universal Clipboard does a lot of the heavy lifting. It works seamlessly as long as you’re signed in with the same Apple ID on all your gadgets, and they’re all near to each other (since it works over a Bluetooth connection).

You might find all the settings have been correctly configured already, but a bit of preparation is still required. Every device needs to have Wi-Fi and Bluetooth on—you can take care of that under Wi-Fi and Bluetooth in Settings on iPhones and iPads; and under Network and Bluetooth in System Preferences on Macs.

All your devices need a feature called Handoff enabled, too. On an iPhone or iPad, go to Settings and choose General, then Handoff to make sure it’s turned on. On a Mac, open System Preferences, choose General, and then enable the Allow Handoff between this Mac and your iCloud devices option.

You can then just copy and paste as normal—pick up something on a Mac with Cmd+C, for example, or via the Edit and Copy menu options. On iPhones and iPads, a long press on text or images will bring up a Copy command. Paste on a Mac with Cmd+V or Edit and Paste. On iPhones and iPads, you’ll need another long press, followed by Paste.

Content copied from other devices stays on the Universal Clipboard “briefly,” Apple says, so it won’t hang around forever. As with traditional clipboards on a single device, anything you copy will be replaced if you copy something new.

Google Chrome

Almost all devices that run Chrome can copy and paste content between them. Not the iPhone, though.

If you’re copying from one device to another, and at least one isn’t made by Apple, using Google Chrome is one of your best options. You can download the browser on just about every laptop and mobile device out there, although this particular feature isn’t yet enabled by default.

For now the ability to share a clipboard between devices is only available on the latest versions of Chrome for Android, Windows, and macOS. It might eventually make it to Chrome for iOS, too, but that hasn’t happened yet.

With Chrome installed, type “chrome://flags” in the address bar and hit Enter. You’ll then need to find Enable receiver device to handle shared clipboard feature, Enable shared clipboard feature signals to be handled, and Sync Clipboard Service, all of which need to be enabled. Use the search option (Ctrl+F on a PC, Cmd+F on macOS) if you’re having trouble finding the flags. This applies wherever you’re using Chrome, on both desktop and mobile devices.

Once that’s done, you’ll need to be signed into the same Google account on Android (under Accounts in Settings) and on your laptop (under Sync and Google services on the Settings pane). As long as both devices have an internet connection, copy and paste should work without any further configuration.

From Chrome on the desktop, right-click on text or images and choose Copy to Your Device, then pick a phone, tablet, or laptop. You can then long-press anywhere in Android and choose Paste to transfer the content. To go the other way, select something in Chrome on Android, then choose Share, and pick the Chrome option—you’ll be able to pick a device. Then, on that device, right-click and choose Paste, or hit Ctrl+V (Windows) or Cmd+V (macOS).

Other options

Copying and pasting across Microsoft devices is actually one of the easiest ways to share links, images, and text.

Those alternatives may be all you need, but if not, there are others available, too. If you want to copy content Windows-to-Windows, for example, the operating system makes it possible, provided you’re using the same Microsoft account on both devices. From Settings, choose System, Clipboard, then enable Sync across devices. Anything you cut or copy from one computer can be pasted on another.

Of the various third-party options, we like Clipbrd (free), which is a Google Chrome extension that works across Android and any desktop version of the browser. Just use copy and paste on your devices as you normally would (via keyboard shortcuts or menu picks), and Clipbrd will take care of the syncing.

We’re also fans of Magic Copy (free), which is available to download for desktop as well as Android and iOS. Just use copy as normal, then open up the Magic Copy app on your current device. That’s enough to copy the chosen content to your cloud clipboard and make it available on every other device on which you’ve installed Magic Copy.

Then there’s Pushbullet (free), which works across Android and iOS, as well as Chrome and Firefox on any platform. It’s more of an extra app on top of your devices rather than an integrated clipboard manager, but it still does the job of letting you transfer text, images, and links wherever you have the app installed.

If you can’t find something suitable that works with the clipboards on your devices, numerous apps let you manage notes, text, and pictures between computers, phones, and tablets. Look at Google Keep, for example, which runs on the web as well as on Android and iOS; or Evernote, which has apps available for just about every platform.

Boeing’s massive wing-folding 777x just flew for the first time

https://www.popsci.com/story/technology/boeing-777x-first-flight-folding-wingtips/

The Boeing 777x made its maiden flight in Everett, Washington on January 25. When it's on the ground, its wingtips fold upwards.

On Saturday, Boeing flew its newest passenger plane for the first time, and after it landed in Seattle, its wingtips did something new to the world of commercial aviation: they folded upwards as the plane was still rolling down the tarmac.

When the new widebody 777x enters service, it will seat as many as 426 people in its longest of two configurations. But while the size of the plane’s fuselage is what allows it to carry so many people, it’s the design of the wings that really sets it apart from an engineering perspective.

In both models of the new aircraft—the 777-8 and the 777-9—the wings will measure 235 feet from tip to folding tip. That’s wider than the wings on existing Boeing 777s or the 787, and about double the wingspan of a 737. With the 777x, Boeing is going to all the trouble to create such a long wing for one simple reason: it allows the plane to be more efficient as it flies. And the company has incorporated the folding, 11-foot-long tips on each wing—and managed the added weight and complexity that comes with such a feature—just to ensure the new airplane can fit at a standard airport gate.

Just like a F/A-18 Super Hornet fighter jet can fold part of its wings to take up less space on an aircraft carrier, the 777x manages its size so that it can politely squeeze into the parking spots at a commercial terminal.

In the air, longer wings create less drag, explains Mark Drela, a professor of aeronautics and astronautics at MIT. “A wing pushes down on the air,” he says. “The longer the wingspan, the more air it can push down on.”

The way the physics work out, a longer wing requires less power to produce the same amount of lift as a shorter wing would need. Drela compares the phenomenon to waterskiing. Imagine a water skier with very narrow skis—the boat would need to use a lot of power to keep them aloft on the water’s surface. The fix is a wider ski. “They’ll have less drag as a result,” he says; the boat can use less power.

A related phenomenon is that the long wings will also produce weaker vortices—rotating air that can form at the wingtips as a result of the wing pushing against it.

But nothing comes for free in aviation: a longer wing weighs more than a shorter one, which explains why airplane makers like Boeing didn’t give its 777 airplanes 235-foot-long wings in the first place. Modern composite materials weigh less, allowing longer wings that are considerably lighter than they would be if they were made out of aluminum. “A composite wing is inherently lighter, therefore its weight overhead is lower,” Drela says, so the wing can be longer. (The mechanisms that allow the tips to fold add weight, but evidently the efficiency math works out in favor of a long, folding wing as opposed to a shorter, more traditional one.)

About 11 feet in diameter and with 16 spinning fan blades, the GE9X is the largest commercial engine that General Electric makes.

Two giant General Electric engines—the biggest commercial thrusters the company has ever made—will speed the 777x through the air. The large, 11-foot-wide GE9X engines are more efficient because a bigger engine can manipulate more air. "A wing pushes the air down, whereas the engine pushes the air back—but in both cases you want to influence as much air as possible,” Drela says. (The engines are each about the same diameter as the fuselage of a 737.)

Just like a longer wing is heavier, so too is a bigger engine, so GE needed to mitigate that. One way they accomplished that is by using composite materials, and another is by designing it with fewer spinning fan blades than other engines: the GE engines on the Boeing Dreamliner rely on 18 blades, the engines on existing 777s contain 22, but the new engines employ just 16.

All of these design changes add up to a 10 percent better fuel efficiency, Boeing claims.

Saturday’s 777x sortie lasted nearly 4 hours over Washington state and included a trip around Mt. Rainier. (And if you look at photos or video from the flight, you’ll see an object streaming behind its tail: that’s a hose and sensor that measures the aircraft’s airspeed; Boeing can compare the data it produces with the cockpit’s display.) The troubled airplane maker plans more test flights, and may hand over new 777x planes to carriers such as British Airways and Singapore Airlines as soon as next year.

Defying Company Policy, Over 300 Amazon Employees Speak Out

https://www.wired.com/story/amazon-employees-protest-communications-policy

While Amazon CEO Jeff Bezos was throwing a lavish party at his $23 million mansion in Washington, DC this weekend—attended by celebrities like Ivanka Trump and Bill Gates—hundreds of his employees were gearing up to revolt.

At issue was the company’s external communications policy, and reports earlier this month that it threatened to fire employees for speaking out about climate change without proper authorization. So on Sunday, more than 350 Amazon workers published statements under their own names in a Medium post, intentionally violating the policy en masse in protest.

The protest was organized by Amazon Employees for Climate Justice, a coalition of activist workers that has pushed for the company to adopt more environmentally friendly policies over the past year. The group organized a climate change walkout last fall that was attended by thousands of Amazon and other tech workers around the globe.

“Corporations cannot own the conversation that threatens our very existence,” wrote Maren Costa, a principal user experience designer at Amazon. “We can’t be silent about issues that harm our children, communities, and planet.” Costa is one of several employees who were told they could be fired if they continued speaking publicly about Amazon without getting advanced approval. In the fall, Costa spoke with several news outlets, including WIRED, about what she said was the company’s inadequate response to the climate crisis.

Amazon has long required employees to get approval before speaking publicly, but the policy wasn’t strictly enforced, according to The Washington Post. In September, right before the walkout, Amazon created a new internal portal for workers to request permission to speak with the press, and are now required to have a “business justification” for doing so.

None of the workers who contributed to Sunday’s Medium post appear to have used that formal channel. “The idea is to intentionally break the communications policy so prolifically that it is unenforceable,” Amazon Employees for Climate Justice wrote in an email sent internally last week to collect statements and signatures; it later made the message public.

Many large companies have policies about external communications, and AECJ acknowledged that Amazon’s policy makes sense in some cases, such as confidential projects. “But allowing a corporation to silence us on its contribution to the climate crisis is a clear overreach of comms policy, and effectively demands we give up our basic humanity and integrity in order to be employees,” the group wrote in its message.

“While all employees are welcome to engage constructively with any of the many teams inside Amazon that work on sustainability and other topics, we do enforce our external communications policy and will not allow employees to publicly disparage or misrepresent the company or the hard work of their colleagues who are developing solutions to these hard problems,” an Amazon spokesperson said in a statement. The spokesperson did not comment on whether Amazon would take action in response to Sunday’s post.

The statements the group published Sunday addressed a range of issues beyond Amazon’s impact on the environment. The Medium post is a laundry list of controversies the company has weathered in recent years, including labor issues, safety and privacy, and political influence, among others.

Not all of the statements were critical of Amazon’s outside communications policy. One worker said it prohibited her from sharing positive opinions with the press. “I want to be able to speak to the media about all the innovative things we ARE doing to protect Alexa customer privacy,” wrote Emily Greene, a software engineer. “I work every day to improve our protections of customer data, and it’s disappointing when the media spins the truth because the people who speak up are the ones with nothing to lose.”

A number of Amazon employees who participated in Sunday’s Medium post commended the company’s recent environmental efforts. Ahead of the walkout in September, Bezos unveiled a new “Climate Pledge,” where businesses promise to regularly disclose greenhouse gas emissions and reach carbon neutrality by 2040. Amazon was the first company to join. “I am proud to work at Amazon and to be working on such an important topic. I feel supported by our company and by our leadership to make this our top priority,” wrote Kimberly Pousman, an engagement manager working on the Climate Pledge.

Germany, Japan, and Taiwan Report First Coronavirus Cases in People Who Haven’t Visited China [Updated]

https://gizmodo.com/germany-and-japan-report-first-coronavirus-cases-in-peo-1841298312

Germany and Japan have reported the first cases of a new SARS-like virus in people who haven’t recently visited China. The announcements, made on Tuesday, come as the number of confirmed cases of 2019-nCoV worldwide reached 4,587 and the death toll hit 106.

The first person to contract the virus in Germany reportedly got it from a “Chinese colleague” while the two were attending a work training session in the state of Bavaria one week ago. The 33-year-old patient, who’s from the town of Starnberg, roughly 18 miles from Munich, was infected by a woman who had been in Wuhan recently to visit her parents. The man, an employee of car parts supplier Webasto, is in a “medically good state,” according to German state media outlet DW.

In Japan, a man in his 60s has also contracted the new coronavirus, according to Japanese news outlet NHK. The unnamed man has not recently traveled to China, but reportedly works as a tour bus driver and came in contact with tourists from Wuhan, the epicenter of the virus outbreak, at least twice this month.

The Japanese patient lives in Nara prefecture in western Japan and first developed symptoms on January 14 and was hospitalized on January 25, according to the Strait Times. The man’s condition has not been released.

Median Age For Cases Outside China is 45

The latest report from the World Health Organization (WHO) notes that the likely incubation period for the virus is 2-10 days, slightly different from the 1-14 day range that had been estimated late last week.

The new report also notes the median age for cases outside of China is currently 45 years and roughly 71 percent of cases outside of China have been men, according to WHO. While most cases outside of China have been in older people, the youngest known case inside China has been a 9-month-old girl in Beijing—one of at least 68 confirmed cases in China’s capital city.

The World Health Organization still hasn’t declared the virus outbreak to be a “public health emergency of international concern,” or PHEIC. Twelve countries have confirmed cases of the virus but China has seen the only deaths so far.

CDC Expands Testing to 20 U.S. Airports

The Centers for Disease Control and Prevention (CDC) has announced that screening for the virus will be expanded to 20 U.S. airports, up from five airports that were doing testing earlier. The 20 U.S. airports now doing thermal screening receive roughly 90 percent of all inbound flights from China, according to CNN.

“We’ve screened somewhere around 2,400 people so far,” the CDC’s Dr. Nancy Messonnier said on a press call Monday. “And as you imagine, the number of people who are coming from Wuhan is declining with the aggressive closure of that city.”

The U.S. Stated Department updated its security warning on Monday advising U.S. residents to avoid any travel to China. Previously the State Department had only advised against travel to Wubei province, which contains Wuhan.

Wuhan Students to Begin Classes Online

The start of spring classes for students in Wuhan has been delayed while the city is on lockdown but online classes for all students will begin on February 10, according to state media outlet CGTN.

Youku, China’s version of YouTube that’s owned by Alibaba, also announced on Monday that it would start offering free classes to students in the region, according to Abacus News. The company will use DingTalk, a Slack-like app, in an education program that already has over 50 schools participating.

Hong Kong Cuts Off Most Travel From Mainland China

Hong Kong officials announced new cases of the virus on Tuesday, and said that all train and ferry travel between Hong Kong and mainland China are being cut off starting January 30. The local government is also cutting the number of flights allowed from China in half.

Hong Kong banned masks last year as pro-democracy protesters took to the streets in an effort to fight political control from Beijing, which made it particularly ironic to see Hong Kong’s chief executive Carrie Lam wearing a facemask today at her press conference on the virus outbreak.

There are currently 8 confirmed cases in Hong Kong, which operates under a “one-country, two systems” form of semi-autonomy from China’s Communist government. 

Financial Markets Might Recover Tuesday After Panic on Monday

The U.S. stock market plunged Monday as investors tried to sell off investments that might be vulnerable to the coronavirus outbreak, recording the Dow’s worst trading day in three months. But it looks like stocks are poised to bounce back today.

The Dow Jones Industrial Average rebounded 85 points in premarket trading Tuesday. Some markets in Asia are still closed for the Lunar New Year and an estimated 50 million people are on lockdown in cities throughout China.

There are still just five confirmed cases of the virus in the U.S., a number that hasn’t changed since yesterday, though at least 110 people in 26 states are still under observation. But we can expect that number to grow as everyone around the world seems to be on high alert for this new public health threat.

Ford develops 3D-printed locking wheel nuts with your biometric signature

https://www.autoblog.com/2020/01/28/ford-3d-printed-biometric-locking-wheel-nuts/

Ford says it has developed a 3D-printed locking wheel nut made using a unique biometric signature based on the driver’s recorded voice in a bid to prevent wheel and tire thefts.

Ford worked with industrial 3D printing supplier EOS to create the locking nuts, which feature unique contours based on the driver’s voice, similar to how some systems use biometric identification based on an iris scan or a fingerprint. Here, engineers record the driver’s voice for at least one second, then use software to convert the resulting soundwave into a physical pattern that can be 3D printed. They then convert the pattern into a circle and use the design for the indentation and key on the locking nut. The nut and key are designed as a single piece, then 3D printed using acid and corrosion-resistant stainless steel.

What’s more, inside the nut are unevenly spaced ribs and indentations to prevent a thief from making a wax imprint of the pattern, since the wax breaks when it’s pulled from the nut. Ford says drivers could also use something like the car’s logo or their initials to create the pattern if they don’t want to record their voice.

For now, the locking nuts are just a concept. But the technology could presumably prevent the kind of theft of wheels from, say, a brand-new Chevrolet Corvette C8, that we saw last week in Detroit. Of course, Ford presumably had these 3D-printed wheel nuts in development long before the C8, which was likely on loan to a journalist or GM employee, ended up on cinderblocks.

Thefts of motor vehicle accessories, which includes wheels and tires, fell 4.1% in 2018 to 272,124 incidents, according to the most recently available FBI statistics. Tire and wheel theft has become a particular problem in Detroit, according to the National Insurance Crime Bureau.

Ford says 3D printing holds enormous promise for automakers by dramatically speeding up tooling and parts production, lowering weight and creating parts that wouldn’t be possible via conventional production techniques. The company says it has used 3D printing for more than 30 years to make prototype parts and shorten development times for new vehicles. Vehicles like the Ford GT, Focus and Mustang GT500 all feature 3D-printed parts.
