An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission is about to start winding down a program that gives $30 monthly broadband discounts to people with low incomes, and says it will have to complete the shutdown by May if Congress doesn't provide more funding. The 2-year-old Affordable Connectivity Program (ACP) was created by Congress, and Democrats have been pushing for more funding to keep it going. But Republican members of Congress blasted the ACP last month, accusing the FCC of being "wasteful."

In a letter, GOP lawmakers complained that most of the households receiving the subsidy already had broadband service before the program existed. They threatened to withhold funding and criticized what they called the "Biden administration's reckless spending spree." The letter was sent by the highest-ranking Republicans on committees with oversight responsibility over the ACP, namely Sen. John Thune (R-SD), Sen. Ted Cruz (R-Texas), Rep. Cathy McMorris Rodgers (R-Wash.), and Rep. Bob Latta (R-Ohio). With no resolution in sight, the FCC announced that it would have to start sending out notices about the program's expected demise. "With less than four months before the projected program end date and without any immediate additional funding, this week the Commission expects to begin taking steps to start winding down the program to give households, providers, and other stakeholders sufficient time to prepare," the FCC said in an announcement yesterday.

The Biden administration has requested $6 billion to fund the program through December 2024. As of now, the FCC said it "expects funding to last through April 2024, running out completely in May." FCC Chairwoman Jessica Rosenworcel has repeatedly asked Congress for more ACP funding, and sent a letter (PDF) to lawmakers yesterday in which she repeated her plea. The chairwoman's letter said that 23 million households are enrolled in the discount program. [...] Rosenworcel warned that the impending ACP shutoff "would undermine the historic $42.5 billion Broadband Equity, Access, and Deployment Program," a different program created by Congress to subsidize ISPs' expansion of broadband networks throughout the US. The discount and deployment programs complement each other because "the ACP supports a stable customer base to help incentivize deployment in rural areas," Rosenworcel wrote.

Long-time Slashdot reader theodp writes: In the January 2024 Communications of the ACM, Rice University professor and former CACM Editor-in-Chief Moshe Y. Vardi minces no words in Computing, You Have Blood on Your Hands!. He argues that the unintended consequences of the rise of social media and mobile computing include hate mongering on a global scale and a worldwide youth mental health crisis.

"How did the technology that we considered 'cool' just a decade ago become an assault weapon used to hurt, traumatize, and even kill vulnerable people?" Vardi asks. "Looking back at my past columns, one can see the forewarnings. Our obsession with efficiency came at the expense of resilience. In the name of efficiency, we aimed at eliminating all friction. In the name of efficiency, it became desirable to move fast and break things, and we allowed the technology industry to become dominated by a very small number of mega corporations. It is time for all computing professionals to accept responsibility for computing's current state. To use Star Wars metaphors, we once considered computing as the 'Rebels,' but it turns out that computing is the 'Empire.' Admitting we have a problem is a necessary first step toward addressing the problems computing has created."
Examples cited in the piece include:

• Amnesty International's 2022 accusation that Meta "substantially contributed" to human rights violations of Myanmar's Rohingya people
• Internal Meta documents saying "We are not actually doing what we say we do publicly" in policing harmful content.

So far the ACM's piece has attracted one comment. "Deep thanks for your long-term commitment to ethics and how you articulate clearly its challenges."

Tuesday's launch was different. "SpaceX launched its first batch of Starlink satellites designed to connect directly to unmodified smartphones..." reports SpaceNews, "after getting a temporary experimental license to start testing the capability in the United States." Six of the 21 Starlink satellites that launched on a Falcon 9 rocket at 10:44 p.m. Eastern from Vandenberg Space Force Base, California, carry a payload that the company said could provide connectivity for most 4G LTE devices when in range. SpaceX plans to start enabling texting from space this year in partnership with cellular operators, with voice and data connectivity coming in 2025, although the company still needs regulatory permission to provide the services commercially. Initial direct-to-smartphone tests would use cellular spectrum from SpaceX's U.S. mobile partner T-Mobile. SpaceX has also partnered with mobile operators in Australia, Canada, Chile, Japan, New Zealand, and Switzerland....

Meanwhile, early-stage ventures AST SpaceMobile and Lynk Global are closing in on fundraising deals to expand their dedicated direct-to-device constellations. AST SpaceMobile said January 2 it is seeking to secure funds this month from "multiple parties" ahead of launching its first five commercial satellites early this year on a Falcon 9. Lynk Global, which is currently providing intermittent texting and other low-bandwidth services to phones outside cellular networks in parts of the Solomon Islands, Cook Islands, and Palau, plans to raise funds by merging with a shell company run by former professional baseball player Alex Rodriguez.

SpaceX launched a total of 21 satellites on Tuesday night, including "the first six Starlink satellites with Direct to Cell capabilities that enable mobile network operators around the world to provide seamless global access to texting, calling, and browsing wherever you may be on land, lakes, or coastal waters without changing hardware or firmware. The enhanced Starlink satellites have an advanced modem that acts as a cellphone tower in space, eliminating dead zones with network integration similar to a standard roaming partner," the company said. Ars Technica reports: Besides T-Mobile in the US, several carriers in other countries have signed up to use the direct-to-cell satellites. SpaceX said the other carriers are Rogers in Canada, KDDI in Japan, Optus in Australia, One NZ in New Zealand, Salt in Switzerland, and Entel in Chile and Peru. While SpaceX CEO Elon Musk wrote that the satellites will "allow for mobile phone connectivity anywhere on Earth," he also described a significant bandwidth limit. "Note, this only supports ~7Mb per beam and the beams are very big, so while this is a great solution for locations with no cellular connectivity, it is not meaningfully competitive with existing terrestrial cellular networks," Musk wrote.

Starlink's direct-to-cell website says the service will provide text messaging only when it becomes available in 2024, with voice and data service beginning sometime in 2025. Starlink's low Earth orbit satellites will work with standard LTE phones, unlike earlier services that required phones specifically built for satellite use. SpaceX's direct-to-cell satellites will also connect with Internet of Things (IoT) devices in 2025, the company says.

Amazon-owned Wickr is dead, more than a year after reports showed it had become the app of choice for drug traffickers. 404 Media: If you open the encrypted messaging app Wickr Me today, you'll be greeted with a line of red text: "Reconnecting..." Below that, in white text over a black background, the app says "We're having issues connecting to the Wickr Me network. If the problem persists, try restarting your app or contacting support." Closing and reopening the app will not work. There is no point in contacting support either. That's because on December 31, 2023, Wickr Me, the free version of Wickr, was shut down entirely.

Wickr Me is no longer available to download on the Apple App Store or the Google Play Store. The app stopped accepting new users more than a year ago. And now, even current users cannot speak to one another. So ends the story of an app that while never reaching the popularity of other encrypted messaging apps like Signal, nor those that later turned on end-to-end encryption for the masses like WhatsApp, nonetheless played an important role in the adoption of and debate around secure communications.

"To prevent disinformation from eroding democratic values worldwide, the U.S. must establish a global watermarking standard for text-based AI-generated content," writes retired U.S. Army Col. Joe Buccino in an opinion piece for The Hill. While President Biden's October executive order requires watermarking of AI-derived video and imagery, it offers no watermarking requirement for text-based content. "Text-based AI represents the greatest danger to election misinformation, as it can respond in real-time, creating the illusion of a real-time social media exchange," writes Buccino. "Chatbots armed with large language models trained with reams of data represent a catastrophic risk to the integrity of elections and democratic norms."

Joe Buccino is a retired U.S. Army colonel who serves as an A.I. research analyst with the U.S. Department of Defense Defense Innovation Board. He served as U.S. Central Command communications director from 2021 until September 2023. Here's an excerpt from his report: Watermarking text-based AI content involves embedding unique, identifiable information -- a digital signature documenting the AI model used and the generation date -- into the metadata generated text to indicate its artificial origin. Detecting this digital signature requires specialized software, which, when integrated into platforms where AI-generated text is common, enables the automatic identification and flagging of such content. This process gets complicated in instances where AI-generated text is manipulated slightly by the user. For example, a high school student may make minor modifications to a homework essay created through Chat-GPT4. These modifications may drop the digital signature from the document. However, that kind of scenario is not of great concern in the most troubling cases, where chatbots are let loose in massive numbers to accomplish their programmed tasks. Disinformation campaigns require such a large volume of them that it is no longer feasible to modify their output once released.

The U.S. should create a standard digital signature for text, then partner with the EU and China to lead the world in adopting this standard. Once such a global standard is established, the next step will follow -- social media platforms adopting the metadata recognition software and publicly flagging AI-generated text. Social media giants are sure to respond to international pressure on this issue. The call for a global watermarking standard must navigate diverse international perspectives and regulatory frameworks. A global standard for watermarking AI-generated text ahead of 2024's elections is ambitious -- an undertaking that encompasses diplomatic and legislative complexities as well as technical challenges. A foundational step would involve the U.S. publicly accepting and advocating for a standard of marking and detection. This must be followed by a global campaign to raise awareness about the implications of AI-generated disinformation, involving educational initiatives and collaborations with the giant tech companies and social media platforms.

In 2024, generative AI and democratic elections are set to collide. Establishing a global watermarking standard for text-based generative AI content represents a commitment to upholding the integrity of democratic institutions. The U.S. has the opportunity to lead this initiative, setting a precedent for responsible AI use worldwide. The successful implementation of such a standard, coupled with the adoption of detection technologies by social media platforms, would represent a significant stride towards preserving the authenticity and trustworthiness of democratic norms.

The number of 18-year-olds in Japan totaled a record low of 1.06 million as of Monday, a government estimate showed, as the country continues to grapple with a falling birthrate. From a report: The number of those that have reached Japan's legal adult age fell by 60,000 from 2023 and accounted for 0.86% of Japan's total population, the Ministry of Internal Affairs and Communications said Sunday. The year 2005, when the new adults were born, had seen the country's total fertility rate -- the average number of children a woman is estimated to bear in her lifetime -- fall to a record-low 1.26, later matched by that of 2022.

NBC News reports that the Chinese spy balloon that flew across the U.S. in February "used an American internet service provider to communicate, according to two current and one former U.S. official familiar with the assessment."

it used the American ISP connection "to send and receive communications from China, primarily related to its navigation." Officials familiar with the assessment said it found that the connection allowed the balloon to send burst transmissions, or high-bandwidth collections of data over short periods of time.

The Biden administration sought a highly secretive court order from the federal Foreign Intelligence Surveillance Court to collect intelligence about it while it was over the U.S., according to multiple current and former U.S. officials. How the court ruled has not been disclosed. Such a court order would have allowed U.S. intelligence agencies to conduct electronic surveillance on the balloon as it flew over the U.S. and as it sent and received messages to and from China, the officials said, including communications sent via the American internet service provider...

The previously unreported U.S. effort to monitor the balloon's communications could be one reason Biden administration officials have insisted that they got more intelligence out of the device than it got as it flew over the U.S. Senior administration officials have said the U.S. was able to protect sensitive sites on the ground because they closely tracked the balloon's projected flight path. The U.S. military moved or obscured sensitive equipment so the balloon could not collect images or video while it was overhead.
NBC News is not naming the internet service provider, but says it denied that the Chinese balloon had used its network, "a determination it said was based on its own investigation and discussions it had with U.S. officials." The balloon contained "multiple antennas, including an array most likely able to collect and geolocate communications," according to reports from a U.S. State Depratment official cited by NBC News in February. "It was also powered by enormous solar panels that generated enough power to operate intelligence collection sensors, the official said.

Reached for comment this week, a spokesperson for the Chinese Embassy in Washington told NBC News that the balloon was just a weather balloon that had accidentally drifted into American airspace.

In 2021, Philips pulled its popular sleep apnea machines and ventilators off the shelves after discovering that an industrial foam built into the devices to reduce noise could release toxic particles and fumes into the masks worn by patients. "But as Philips publicly pledged to send out replacements, supervisors inside the company's headquarters near Pittsburgh were quietly racing to manage a new crisis that threatened the massive recall and posed risks to patients all over again," reports ProPublica. "Tests by independent laboratories retained by Philips had found that a different foam used by the company -- material fitted inside the millions of replacement machines -- was also emitting dangerous chemicals, including formaldehyde, a known carcinogen."

"Though Philips has said the machines are safe, ProPublica and the Pittsburgh Post-Gazette obtained test results and other internal records that reveal for the first time how scientists working for the company grew increasingly alarmed and how infighting broke out as the new threat reached the highest levels of the Pittsburgh operation. The findings also underscore an unchecked pattern of corporate secrecy that began long before Philips decided to use the new foam." From the report: The company had previously failed to disclose complaints about the original foam in its profitable breathing machines, a polyester-based polyurethane material that was found to degrade in heat and humidity. Former patients and others have described hundreds of deaths and thousands of cases of cancer in government reports. After the introduction of the new foam in 2021, this one made of silicone, the company again held back details about the problem from the public even as it sent out replacement machines with the new material to customers around the world.

One of the devices was the DreamStation 2, a newly released continuous positive airway pressure, or CPAP, machine promoted as one of the company's primary replacements. Federal regulators were alerted to the concern more than two years ago but said in a news release at the time that the company was carrying out additional tests on the foam and that patients should keep using their replacements until more details were available. The Food and Drug Administration has not provided new information on the test results since then, and it is still unclear whether the material is safe. That leaves millions of people in the United States alone caught in the middle, including those with sleep apnea, which causes breathing to stop and start through the night and can lead to heart attacks, strokes and sudden death.

The new foam isn't the only problem: An internal investigation at Philips launched in the months after the recall found that water was condensing in the circuitry of the DreamStation 2, creating a new series of safety risks. "Loss of therapy, thermal events, and shock hazards," the investigation concluded. The FDA issued an alert about overheating last month, warning that the devices could produce "fire, smoke, burns, and other signs of overheating" and advising patients to keep the machines away from carpet, fabric and "other flammable materials." Philips has said that customers could continue using the devices if they followed safety instructions. ...

Multi-link operations and the 6-GHz band promise more reliability than before. From a report: The key to a future Wi-Fi you can depend on is something called multi-link operations (MLO). "It is the marquee feature of Wi-Fi 7," says Kevin Robinson, president and CEO of the Wi-Fi Alliance. MLO comes in two flavors. The first -- and simpler -- of the two is a version that allows Wi-Fi devices to spread a stream of data across multiple channels in a single frequency band. The technique makes the collective Wi-Fi signal more resilient to interference at a specific frequency. Where MLO really makes Wi-Fi 7 stand apart from previous generations, however, is a version that allows devices to spread a data stream across multiple frequency bands. For context, Wi-Fi utilizes three bands-2.5 gigahertz, 5 GHz, and as of 2020, 6 GHz.

Whether MLO spreads signals across multiple channels in the same frequency band or channels across two or three bands, the goals are the same: dependability and reduced latency. Devices will be able to split up a stream of data and send portions across different channels at the same time -- which cuts down on the overall transmission time -- or beam copies of the data across diverse channels, in case one channel is noisy or otherwise impaired. MLO is hardly the only feature new to Wi-Fi 7, even if industry experts agree it's the most notable. Wi-Fi 7 will also see channel size increase from 160 megahertz to a new maximum of 320 MHz. Bigger channels means more throughput capacity, which means more data in the same amount of time.

That said, 320-MHz channels won't be universally available. Wi-Fi uses unlicensed spectrum -- and in some regions, contiguous 320-MHz chunks of unlicensed spectrum don't exist because of other spectrum allocations. In cases where full channels aren't possible, Wi-Fi 7 includes another feature, called puncturing. "In the past, let's say you're looking for 320 MHz somewhere, but right within, there's a 20-MHz interferer. You would need to look at going to either side of that," says Andy Davidson, senior director of technology planning at Qualcomm. Before Wi-Fi 7, you'd functionally be stuck with about a 160-MHz channel either above or below that interference.

"The iMessage connection software that powers Beeper Mini and Beeper Cloud is now 100% open source," Beeper announced late this week. " Anyone who wants can use it or continue development."

But while Beeper says it's done trying to bring iMessage to Android, CNET reports that the whole battle was "deeply tied" to Apple's ongoing strategy to control the mobile market: The tide seems to be changing, however: Apple said last month it would be opening up its Messages app (likely due to European regulation) to work with the newer, more feature-rich texting protocol called RCS. This hopefully will lead to a more modern and secure messaging experience when texting between an iPhone and an Android phone, and lead away from the aging SMS and MMS standards. Unfortunately, green bubbles will continue to persist even if there might be little to no functional difference. While third-party apps like Nothing Chats attempted and ultimately failed to bring iMessage to Android, Apple will likely never release the app on Google's mobile operating system.

Until RCS is fully adopted, companies are creating services to allow access to iMessage via Android phones. Apple, for its part, has been quick to block apps like Beeper Mini, citing security concerns. This, however, is raising eyebrows from lawmakers regarding competition in the messaging space and Apple's tight control over the market...

Beeper in a December 21 blog post told users to grab a jailbroken iPhone and install a free Beeper tool that'll generate iMessage registration codes to keep the service operational. It's such a roundabout and potentially expensive way of trying to get iMessage on Android that it likely won't be worth it for most people. For those not willing to go out and jailbreak an iPhone, Beeper said in a now-deleted blog post that it would allow people to rent a jailbroken unit for a small monthly fee starting next year.

An anonymous reader shared this report from Reuters: In February, a Canadian cybersecurity firm delivered an ominous forecast to the U.S. Department of Defense. America's secrets — actually, everybody's secrets — are now at risk of exposure, warned the team from Quantum Defen5e (QD5). QD5's executive vice president, Tilo Kunz, told officials from the Defense Information Systems Agency that possibly as soon as 2025, the world would arrive at what has been dubbed "Q-day," the day when quantum computers make current encryption methods useless. Machines vastly more powerful than today's fastest supercomputers would be capable of cracking the codes that protect virtually all modern communication, he told the agency, which is tasked with safeguarding the U.S. military's communications.

In the meantime, Kunz told the panel, a global effort to plunder data is underway so that intercepted messages can be decoded after Q-day in what he described as "harvest now, decrypt later" attacks, according to a recording of the session the agency later made public. Militaries would see their long-term plans and intelligence gathering exposed to enemies. Businesses could have their intellectual property swiped. People's health records would be laid bare... One challenge for the keepers of digital secrets is that whenever Q-day comes, quantum codebreakers are unlikely to announce their breakthrough. Instead, they're likely to keep quiet, so they can exploit the advantage as long as possible.
The article adds that "a scramble is on to protect critical data. Washington and its allies are working on new encryption standards known as post-quantum cryptography... Beijing is trying to pioneer quantum communications networks, a technology theoretically impossible to hack, according to researchers...

"In a quantum communications network, users exchange a secret key or code on subatomic particles called photons, allowing them to encrypt and decrypt data. This is called quantum key distribution, or QKD."

During a meeting of the National Space Council, Vice President Kamala Harris said an international astronaut will land on the Moon during one of NASA's Artemis missions. "Today, in recognition of the essential role that our allies and partners play in the Artemis program, I am proud to announce that alongside American astronauts, we intend to land an international astronaut on the surface of the Moon by the end of the decade," Harris said. Ars Technica reports: Although the National Space Council is useful in aggregating disparate interests across the US government to help form more cohesive space policies, public meetings like the one Wednesday can seem perfunctory. Harris departed the stage soon after her speech, and other government officials read from prepared remarks during the rest of the event. Nevertheless, Harris' announcement highlighted the role the space program plays in elevating the soft power of the United States. It was widely assumed an international astronaut would eventually land on the Moon with NASA. Harris put a deadline on achieving this goal.

NASA has long included astronauts from its international partners on human spaceflight missions, dating back to the ninth flight of the space shuttle in 1983, when West German astronaut Ulf Merbold joined five Americans on a flight to low-Earth orbit. This was seen by US government officials as a way to foster closer relations with like-minded countries. The inclusion of foreign astronauts on US missions also repays partner nations who make financial commitments to US-led space projects with a high-profile flight opportunity for one of their citizens.

Among the international partners contributing to Artemis, it seems most likely a European astronaut would get the first slot for a landing with NASA. ESA funded the development of the service modules used on NASA's Orion spacecraft, which will ferry astronauts from Earth to the Moon and back. These modules provide power and propulsion for Orion. ESA is also developing refueling and communications infrastructure for the Gateway mini-space station to be constructed in orbit around the Moon.

A Japanese astronaut might also have a shot at getting a seat on an Artemis landing. Japan's government has committed to providing the life-support system for the Gateway's international habitation module, along with resupply services to deliver cargo to Gateway. Japan is also interested in building a pressurized rover for astronauts to drive across the lunar surface. In recognition of Japan's contributions, NASA last year committed to flying a Japanese astronaut aboard Gateway. Canada is building a robotic arm for Gateway, but a Canadian astronaut already has a seat on NASA's first crewed Artemis mission, albeit without a trip to the lunar surface.

Longtime Slashdot reader Kreuzfeld writes: Help please: here in Lawrence, Kansas, the public school district has recently started using Gaggle (source may be paywalled; alternative source), a system for monitoring all digital documents and communications created by students on school-provided devices.

Tom Warren and Ash Parrish report via The Verge: Activision Blizzard CEO Bobby Kotick is stepping down officially December 29th. Microsoft has not appointed a direct replacement and instead has rolled the suite of Activision Blizzard executives -- including Blizzard president Mike Ybarra, Activision publishing president Rob Kostich, and Activision Blizzard vice chair Thomas Tippl -- under Microsoft's game content and studios president Matt Booty. Kotick's departure comes just two months after some big Xbox leadership changes that saw Sarah Bond promoted to Xbox president, leading all Xbox platform and hardware work, and Matt Booty promoted to president of game content and studios, including overseeing Bethesda and ZeniMax studios. Now Booty is getting even more responsibilities with Bethesda, Activision Blizzard, and Xbox Game Studios all under his watch.

Microsoft is largely keeping the leadership team of Activision Blizzard in place, with some executive-level exceptions. Activision Blizzard chief communications officer Lulu Meservey will leave the company at the end of January. Humam Sakhnini (vice chairman, Blizzard and King) will also depart at the end of December. A number of Activision Blizzard executives will depart in March, too. Brian Bulatao (chief administrative officer), Julie Hodges (chief people officer), Armin Zerza (chief financial officer), and Grant Dixton (chief legal officer) are all reporting to their Microsoft Gaming equivalents. While Thomas Tippl (vice chairman, Activision Blizzard) is reporting to Matt Booty for now, he will depart Microsoft in March alongside other Activision Blizzard executives. "Thomas, Brian, Julie, Grant and Armin will continue to help us with the transition through March 2024," says Xbox chief Phil Spencer, in an internal memo obtained by The Verge.

Additionally, a memo from Matt Booty announced some of the changes taking place at ZeniMax and Bethesda, including that Jill Braff has been named the new head of those studios. Braff worked on the integration team when ZeniMax and Bethesda joined Xbox back in 2021 and will lead the studios' development teams. [Both memos can be read below The Verge's reporting.]

A worrying number of UK authorities are still unaware of the impending switch-off of 2G and 3G mobile networks, according to Local Government Association (LGA) figures. From a report: While 38 percent of respondents were fully aware, 27 percent were only partially aware, and 7 percent had no idea at all that the axe would be falling by 2033 at the latest. The numbers worsened when the researchers spoke to respondents in senior management. Almost half (48 percent) were "partially aware" the UK's 2G and 3G mobile networks were due to be switched off and 14 percent were not at all aware.

The actual switch-off will happen over the next few years. UK mobile operators have told government they do not intend to offer 2G and 3G mobile networks past 2033 at the latest, and there is a high likelihood that some networks will be shut down earlier. The UK government said it welcomes plans to end services ahead of time. Vodafone, for example, intends to pull the plug on 3G once and for all from January 2024. Although most consumers, with their 4G and 5G devices, will likely be unaware of the end when it comes, the same cannot be said of local authorities. According to the survey, almost two-thirds of respondents (63 percent) reported that their authority was still using devices or services reliant on 2G and 3G networks.

When hurricane Larry made landfall in the Atlantic in 2021, it was depositing over 100,000 microplastics per square meter of land per day. The findings have been published in the journal Communications Earth and Environment. Wired reports: As hurricane Larry curved north in the Atlantic in 2021, sparing the eastern seaboard of the United States, a special instrument was waiting for it on the coast of Newfoundland. Because hurricanes feed on warm ocean water, scientists wondered whether such a storm could pick up microplastics from the sea surface and deposit them when it made landfall. Larry was literally a perfect storm: Because it hadn't touched land before reaching the island, anything it dropped would have been scavenged from the water or air, as opposed to, say, a highly populated city, where you'd expect to find lots of microplastics. [...]

The instrument in a clearing on Newfoundland was quite simple: a glass cylinder, holding a little bit of ultrapure water, securely attached to the ground with wooden stakes. Every six hours before, during, and after the hurricane, the researchers would come and empty out the water, which would have collected any particles falling -- both with and without rain -- on Newfoundland. "It's just a place that experiences a lot of extreme weather events," says Earth scientist Anna Ryan of Dalhousie University, lead author of the paper. "Also, it's fairly remote, and it's got a pretty low population density. So you don't have a bunch of nearby sources of microplastics."

The team found that even before and after Larry, tens of thousands of microplastics fell per square meter of land per day. But when the hurricane hit, that figure spiked up to 113,000. "We found a lot of microplastics deposited during the peak of the hurricane," says Ryan, "but also, overall deposition was relatively high compared to previous studies." These studies were done during normal conditions, but in more remote locations, she says. The researchers also used a technique known as back trajectory modeling -- basically simulating where the air that arrived at the instrument had been previously. That confirmed that Larry had picked up the microplastics at sea, lofted them into the air, and dumped them on Newfoundland. [...] The Newfoundland study notes that Larry happened to pass over the garbage patch of the North Atlantic Gyre, where currents accumulate floating plastic.

NASA has successfully beamed an ultra-high definition streaming video from a record-setting 19 million miles away. The Deep Space Optical Communications experiment, as it is called, is part of a NASA technology demonstration aimed at streaming HD video from deep space to enable future human missions beyond Earth orbit. From a NASA press release: The [15-second test] video signal took 101 seconds to reach Earth, sent at the system's maximum bit rate of 267 megabits per second (Mbps). Capable of sending and receiving near-infrared signals, the instrument beamed an encoded near-infrared laser to the Hale Telescope at Caltech's Palomar Observatory in San Diego County, California, where it was downloaded. Each frame from the looping video was then sent "live" to NASA's Jet Propulsion Laboratory in Southern California, where the video was played in real time.

The laser communications demo, which launched with NASA's Psyche mission on Oct. 13, is designed to transmit data from deep space at rates 10 to 100 times greater than the state-of-the-art radio frequency systems used by deep space missions today. As Psyche travels to the main asteroid belt between Mars and Jupiter, the technology demonstration will send high-data-rate signals as far out as the Red Planet's greatest distance from Earth. In doing so, it paves the way for higher-data-rate communications capable of sending complex scientific information, high-definition imagery, and video in support of humanity's next giant leap: sending humans to Mars.

Uploaded before launch, the short ultra-high definition video features an orange tabby cat named Taters, the pet of a JPL employee, chasing a laser pointer, with overlayed graphics. The graphics illustrate several features from the tech demo, such as Psyche's orbital path, Palomar's telescope dome, and technical information about the laser and its data bit rate. Tater's heart rate, color, and breed are also on display. There's also a historical link: Beginning in 1928, a small statue of the popular cartoon character Felix the Cat was featured in television test broadcast transmissions. Today, cat videos and memes are some of the most popular content online. "Despite transmitting from millions of miles away, it was able to send the video faster than most broadband internet connections," said Ryan Rogalin, the project's receiver electronics lead at JPL. "In fact, after receiving the video at Palomar, it was sent to JPL over the internet, and that connection was slower than the signal coming from deep space. JPL's DesignLab did an amazing job helping us showcase this technology -- everyone loves Taters."

Bill McGuire is professor emeritus of climate hazards at University College London. He also writes on CNN that it's "essential" to laugh in the face of the climate crisis: If you don't laugh, you will cry, and that marks the beginning of a very slippery slope. As civilization faces a threat that dwarfs that of every war ever fought combined, and the outcome of the latest climate COP offers little hope, it's something we need — not only to remember — but to actively adopt as a weapon in our armoury to fight for a better future for our children and their children. They say that laughter is the best medicine, but weaponised comedy has the potential to do more than just make us feel good. Not only can it help inform and educate about global heating and the climate breakdown it is driving, but also to encourage and bolster action...

This is why ventures like "Climate Science Translated," which I took part in earlier this year, are so important. The British-based project — brainchild of ethical insurer Nick Oldridge and the climate communications outfit Utopia Bureau — teams climate scientists up with comedians, who 'translate' the science into bite-sized, funny and pretty irreverent chunks that can be understood, digested and appreciated by anyone.
You can see four of the videos on their web site. "Climate science is complicated," each video begins. "So we're translating it into human."

For example, last month Dr. Friederike Otto, senior lecturer on climate science at London's Imperial College, created a new video with comedian Nish Kumar: Dr. Otto: Human-caused climate change is fundamentally changing the fabric of the weather as we know it. It's leading to events which we've simply never seen before.

Comedian Kumar: Translation: Weather used to be clouds. Now we've made it into a sort of Rottweiler on steroids that wants to chew everyone's head off.

Dr. Otto: The continuing increase in global average temperature is already causing higher probabilities of extreme rainfall and flash flooding, as well more intense storms, prolonged droughts, record-breaking heatwaves, and wildfires.

Kumar: Very soon climate scientists are just going to ditch their graphs and point out the window with an expression that says, "I fucking told you!"

Dr. Otto: This is not a problem just for our children and grandchildren. This is an immediate threat to all our lives.

Kumar: I don't know if you're familiar with the film The Terminator, but if someone came from the future to warn us of this threat, they'd have travelled from next Wednesday.
And three weeks ago a follow-up video came from earth systems science professor Mark Maslin from London's University College, teaming up with comedian Jo Brand: Professor Maslin: We are heading for unknown territory if we trigger tipping points — irreversible threshholds which shift our entire ecosystem into a different state.

Comedian Brand: If you liked climate crisis, you're going to love climate complete fucking collapse...

Professor Maslin: The irony is solar and wind power are now over 10 times cheaper than oil and gas. We can still prevent much of the damage, and end up in a better place for everyone.

Brand: With wind and sun power, we save money, and don't die. It's a pretty strong selling point.

Professor Maslin: Most people actually are in favor of urgent action. The reason governments are not transitioning fast enough is because the fossil fuel industry has a grip on many politicians. In fact, governments subsidize them with our taxpayer money — over $1 trillion a year, according to the IMF.

Brand: We are paying a bunch of rich dudes one trillion dollars a year to fuck up our future. I'd do it for that money. When can I start?
Each video ends with the words "All Hands On Deck Now", urging action by voting, contacting your representative, joining a local group, and protesting.

Climate hazard professor Bill McGuire writes on CNN that he hopes to see a growing movement: As Kiri Pritchard-McLean pointedly observes: "If comedians are helping scientists out, you know things aren't going well...." There is even a "Sustainable Stand-up" course aimed at teaching comedy beginners about how climate and social issues can be addressed in their shows, and which has run in 11 countries.

Researchers from the City University of Hong Kong have developed a special antenna that can control all five important aspects of electromagnetic waves using computer software. Interesting Engineering reports: The antenna, which they have named 'microwave universal metasurface antenna,' is capable of dynamically, simultaneously, independently, and precisely manipulating all the essential properties of electromagnetic waves through software control. [...] The antenna adjusts how strong the waves are, their timing, frequency, direction, and even the way they vibrate, all at the same time. It's the first time anyone has made an antenna that can do all these things simultaneously, marking a significant breakthrough in this field.

The antenna is special because it can be used in advanced information systems, like the ones we might have in the future. It's great for handling a lot of data and keeping that data very safe. It can also transfer power wirelessly, meaning it can charge devices without physical connections. One cool thing about this antenna is that it can control the direction of its signals, adding an extra layer of privacy and security. This makes it a good choice for communication systems where we want to ensure nobody can eavesdrop or secretly listen in on our conversations.

Although demonstrated in the microwave band, the UMA's concept can be expanded to terahertz frequencies using specific technologies, enabling applications in augmented reality, holography, integrated sensing and communications for 6G, quantum optics, and quantum information science, noted the researchers in their study. The study has been published in the journal Nature Communications.
