Rocket Engine Exhaust Pollution Extends High Into Earth's Atmosphere

Slashdot - Thu, 2022-05-19 07:00
The American Institute of Physics reports via Phys.Org: In Physics of Fluids, researchers from the University of Nicosia in Cyprus assessed the potential impact of a rocket launch on atmospheric pollution by investigating the heat and mass transfer and rapid mixing of the combustion byproducts for altitudes up to 67 kilometers into the atmosphere. The team modeled the exhaust gases and developing plume at several altitudes along a typical trajectory of a standard present-day rocket. They did this as a prototypical example of a two-stage rocket to transport people and payloads into Earth's orbit and beyond. The researchers found the production of thermal nitrogen oxides (NOx), components of the combustion exhaust, can remain high up to altitudes with an ambient atmospheric pressure above or even slightly below the nozzles' exit pressure, i.e., below an altitude of approximately 10 km. At the same time, the emitted mass of carbon dioxide as the rocket climbs 1 kilometer in altitude in the mesosphere is equivalent to that contained in 26 cubic kilometers of atmospheric air at the same altitude. They found the impact on the atmosphere locally and momentarily in the mesosphere can be significant. While air currents will gradually transport and mix the exhaust CO2 throughout the atmosphere, eventually bringing the CO2 back down to its naturally occurring levels, the time scale over which this happens is not clear. The scientists believe a certain number of rocket launches might still exist above which mesospheric carbon dioxide could accumulate over time, thus increasing the naturally occurring levels and affecting our climate. Their results suggest that in the worst-case scenario, sufficient NOx could be produced over the time it takes the rocket to reach an altitude of 10 kilometers to pollute over 2 cubic kilometers of atmospheric air with a NOx concentration that, according to the World Health Organization, would be at a level hazardous to human health.

New Bluetooth Hack Can Unlock All Kinds of Devices

Slashdot - Thu, 2022-05-19 03:30
An anonymous reader quotes a report from Ars Technica: When you use your phone to unlock a Tesla, the device and the car use Bluetooth signals to measure their proximity to each other. Move close to the car with the phone in hand, and the door automatically unlocks. Move away, and it locks. This proximity authentication works on the assumption that the key stored on the phone can only be transmitted when the locked device is within Bluetooth range. Now, a researcher has devised a hack that allows him to unlock millions of Teslas -- and countless other devices -- even when the authenticating phone or key fob is hundreds of yards or miles away. The hack, which exploits weaknesses in the Bluetooth Low Energy standard adhered to by thousands of device makers, can be used to unlock doors, open and operate vehicles, and gain unauthorized access to a host of laptops and other security-sensitive devices. [...] [The] attack uses custom software and about $100 worth of equipment. [Sultan Qasim Khan, a principal security consultant and researcher at security firm NCC Group] has confirmed it works against the Tesla Model 3 and Model Y and Kevo smart locks marketed under the Kwikset and Weiser brand names. But he says virtually any BLE device that authenticates solely on proximity -- as opposed to also requiring user interaction, geolocation querying, or something else -- is vulnerable. "The problem is that BLE-based proximity authentication is used in places where it was never safe to do so," he explained. "BLE is a standard for devices to share data; it was never meant to be a standard for proximity authentication. However, various companies have adopted it to implement proximity authentication." Because the threat isn't caused by a traditional bug or error in either the Bluetooth specification or an implementation of the standard, there's no CVE designation used to track vulnerabilities. Khan added: "In general, any product relying on BLE proximity authentication is vulnerable if it does not require user interaction on the phone or key fob to approve the unlock and does not implement secure ranging with time-of-flight measurement or comparison of the phone/key fob's GPS or cellular location relative to the location of the device being unlocked. GPS or cellular location comparison may also be insufficient to prevent short distance relay attacks (such as breaking into a home's front door or stealing a car from the driveway, when the owner's phone or key fob is inside the house)." There's a few countermeasures one can take to mitigate this attack. "One mechanism is to check the location of the authenticating device to ensure that it is, in fact, physically close to the locked car or other device," reports Ars. "Another countermeasure is to require the user to provide some form of input to the authenticating device before it's trusted." The phone's accelerometer could also be used to measure its movements. The advisories published by NCC Group can be found here, here, and here.

Solar-Powered Desalination Device Wins MIT $100K Competition

Slashdot - Thu, 2022-05-19 02:02
The winner of this year's MIT $100K Entrepreneurship Competition is commercializing a new water desalination technology. MIT News reports: Nona Desalination says it has developed a device capable of producing enough drinking water for 10 people at half the cost and with 1/10th the power of other water desalination devices. The device is roughly the size and weight of a case of bottled water and is powered by a small solar panel. The traditional approach for water desalination relies on a power-intensive process called reverse osmosis. In contrast, Nona uses a technology developed in MIT's Research Laboratory of Electronics that removes salt and bacteria from seawater using an electrical current. "Because we can do all this at super low pressure, we don't need the high-pressure pump [used in reverse osmosis], so we don't need a lot of electricity," says Crawford, who co-founded the company with MIT Research Scientist Junghyo Yoon. "Our device runs on less power than a cell phone charger." The company has already developed a small prototype that produces clean drinking water. With its winnings, Nona will build more prototypes to give to early customers. The company plans to sell its first units to sailors before moving into the emergency preparedness space in the U.S., which it estimates to be a $5 billion industry. From there, it hopes to scale globally to help with disaster relief. The technology could also possibly be used for hydrogen production, oil and gas separation, and more.

Older People Using TikTok To Defy Ageist Stereotypes, Research Finds

Slashdot - Thu, 2022-05-19 01:25
Older TikTok users are using the online platform, regarded as the virtual playground of teenagers, to defy ageist stereotypes of elderly people as technophobic and frail. The Guardian reports: Research has found increasing numbers of accounts belonging to users aged 60 and older with millions of followers. Using the platform to showcase their energy and vibrancy, these TikTok elders are rewriting expectations around how older people should behave both on and off social media. "These TikTok elders have become successful content creators in a powerful counter-cultural phenomenon in which older persons actually contest the stereotypes of old age by embracing or even celebrating their aged status," said Dr Reuben Ng, the author of the paper Not Too Old for TikTok: How Older Adults are Reframing Ageing, and an assistant professor at Yale University. Interestingly, said Ng, most TikTok elders are women who "fiercely resist common stereotypes of older women as passive, mild-mannered and weak, instead opting to present themselves as fierce or even foul-mouthed," he said. [...] The paper looked at 1,382 videos posted by TikTok users who were aged 60 or older and had between 100,000 and 5.3 million followers. In total, their videos, all of which explicitly discussed their age, had been viewed more than 3.5 billion times. Ng found that 71% of these videos -- including those from accounts such as grandadjoe1933, who has 5.3 million followers, and dolly_broadway, who has 2.4 million followers -- were used to defy age stereotypes. A recurring motif was the "glamma", a portmanteau combining "glamorous" and "grandma", with videos including those of a 70-year-old woman joyfully parading around the streets in a midriff-bearing top. Almost one in five of the videos analyzed made light of age-related vulnerabilities, and one in 10 called out ageism among both younger people and their own contemporaries. Other videos positioned older users as superior to younger people. "I may be 86 but I can still drink more than you lightweights" says one clip. "I may be 86 but I can still twerk better than you," says another, showing an octogenarian leaping up from a fall down the stairs with a twerk.

Netflix Customers Canceling Service Increasingly Includes Long-Term Subscribers

Slashdot - Thu, 2022-05-19 00:45
Netflix lost 200,000 subscribers last quarter and potentially two million this current period, according to a note to shareholders from last month. Now, new research highlights that the number of long-standing subscribers canceling Netflix rose precipitously in the past few years. 9to5Mac reports: The data provided by the research firm Antenna to The Information shows that people who had been subscribers for more than three years accounted for just 5% of total cancelations at the start of 2022, while it hit 13% in the first quarter of 2022: "Newbie subscribers, meantime, accounted for only 60% of cancellations in the quarter, down from 64% in the fourth quarter. Also in the first quarter, overall cancellations rose to 3.6 million people, compared with around 2.5 million in each of the preceding five quarters. Antenna says it draws its data from a panel of 5 million Americans who anonymously contribute their streaming subscriptions." While Netflix is losing ground, the streaming market as a whole is gaining more subscribers, and Antenna's data suggest a connection between the price increase and Netflix's subscriber losses: "'Consumers vote with their wallets on a monthly basis, and now there are just more viable candidates on the ballot,' said Brendan Brady, media and entertainment lead at Antenna. Also, since many entertainment companies, like NBCUniversal and Disney, have pulled their shows off Netflix and put them on their own services, Netflix has had to rely more on its originals, which have been hit or miss, he said."

Apple Reverses Remote Work Policy After Machine Learning Head Decamps To Alphabet

Slashdot - Thu, 2022-05-19 00:02
An anonymous reader quotes a report from Gizmodo: One of Apple's highest-profile return-to-office detractors reportedly landed a new gig at Alphabet's DeepMind, marking the latest drama over Big Tech's remote work scuffles. That move, ironically, comes right around the same time Apple decided to walk back its most recent return-to-office push. In an internal memo viewed by Bloomberg Tuesday, the company said it will delay its three-day in-office work requirement set to take effect on May 23. The memo reportedly cited the recent uptick in covid-19 cases for the delay and didn't provide any hard date for when they'd try again. Apple workers are still required to work in the office two days per week and will now have to wear masks in common areas. At the same time, Ian Goodfellow, Apple's former Director of Machine Learning, who dramatically left the company at least in part over its remote work restrictions, will reportedly join Alphabet's DeepMind. Sources told Bloomberg Goodfellow will join DeepMind as an "individual contributor." He had previously worked as a senior researcher at Google back in 2019. That job switch marks a major blow for Apple, a company that's struggled to appease workers at odds with its return to work strategy. Goodfellow, who's the most senior member known to have jumped ship over remote work so far, reportedly addressed the issue directly in a note to staff obtained by The Verge's Zoe Schiffer. "I believe strongly that more flexibility would have been the best policy for my team," Goodfellow reportedly wrote. The report notes that Alphabet hasn't fully embraced a remote-first office either, "thought previous reports suggest Google more regularly approves remote requests [than Apple]." As office returns accelerate, many workers are willing to give up their jobs over workplace flexibility. According to a survey of 1,000 U.S. adults last year, 39% said they "would consider quitting if their employers weren't flexible about remote work." That figure was 49% among millennials and Gen Z.

The Passwords Most Used By CEOs Are Startlingly Dumb

Slashdot - Wed, 2022-05-18 23:20
A recent cybersecurity report shows how immensely idiotic many CEOs and business owners can be, considering the strength of their chosen account passwords. PC Gamer reports: The research comes from NordPass password manager which identified back in 2020 that the general public's most commonly used passwords were sequential numbers like '123456', 'picture1', and yep, you guessed it: 'password'. The more recent research sample consists of 290 million cybersecurity data breaches around the globe, and denotes the job level of those affected. Turns out, when it comes to CEOs and other high-ranking businesses execs, their password choices are much the same as the general public, although many often feature names. Tiffany was spotted in 100,534 breaches; then there was Charlie with 33,699; Michael was found 10,647 times; and Jordan, 10,472 times. The report also ranks mythical creatures and animals as some of the top passwords to have been cracked in data breaches. 'Dragon' was spotted 11,926 times, and 'monkey' comes in at 11,675. I spoke to IT support engineer Ash Smith, who recommends that companies should consider handing out randomly generated passwords as new accounts are created. "Arguably the strongest passwords are 3 random words, something that you can make a story about in your head to help you remember," he says.
