An anonymous reader quotes a report from The Intercept: The Mozilla Foundation,the entity behind the web browser Firefox, is blocking various censorship circumvention add-ons for its browser, including ones specifically to help those in Russia bypass state censorship. The add-ons were blocked at the request of Russia's federal censorship agency, Roskomnadzor -- the Federal Service for Supervision of Communications, Information Technology, and Mass Media -- according to a statement by Mozilla to The Intercept. "Following recent regulatory changes in Russia, we received persistent requests from Roskomnadzor demanding that five add-ons be removed from the Mozilla add-on store," a Mozilla spokesperson told The Intercept in response to a request for comment. "After careful consideration, we've temporarily restricted their availability within Russia. Recognizing the implications of these actions, we are closely evaluating our next steps while keeping in mind our local community."

Developers of digital tools designed to get around censorship began noticing recently that their Firefox add-ons were no longer available in Russia. On June 8, the developer of Censor Tracker, an add-on for bypassing internet censorship restrictions in Russia and other former Soviet countries, made a post on the Mozilla Foundation's discussion forums saying that their extension was unavailable to users in Russia. The developer of another add-on, Runet Censorship Bypass, which is specifically designed to bypass Roskomnadzor censorship, posted in the thread that their extension was also blocked. The developer said they did not receive any notification from Mozilla regarding the block. Two VPN add-ons, Planet VPN and FastProxy -- the latter explicitly designed for Russian users to bypass Russian censorship -- are also blocked. VPNs, or virtual private networks, are designed to obscure internet users' locations by routing users' traffic through servers in other countries. "It's a kind of unpleasant surprise because we thought the values of this corporation were very clear in terms of access to information, and its policy was somewhat different," said Stanislav Shakirov, the chief technical officer of Roskomsvoboda, a Russian open internet group. "And due to these values, it should not be so simple to comply with state censors and fulfill the requirements of laws that have little to do with common sense."

The dream of perpetual, emissionless flight is getting closer to reality. Aviation giants, telecoms, investors, and military agencies are pouring millions into developing these prototypes, which could revolutionize aerial surveillance, emergency communications, and more.

Solar planes absorb energy via panels covering their wings and bodies, allowing them to fly indefinitely as long as the sun shines. Advances in battery technology now enable longer flights and overnight operation, albeit with less power than jet fuel. These slow, lightweight aircraft can fly at altitudes and durations impossible for humans, making them ideal for monitoring, telecom, and disaster response. Companies like BAE Systems, Airbus, and Skydweller are racing to commercialize solar planes, with hopes of offering services by 2026-2027. The unregulated stratosphere is a key focus, with planes acting as "steerable satellites." WSJ adds: Most of the companies trying to commercialize solar planes are building aircraft that are lightweight, autonomous and can fly at altitudes and for lengths of time that humans can't tolerate. Unlike balloons, solar planes are steerable, a big advantage for monitoring a target on the ground or providing telecom coverage without being blown off course. They are also cheaper and closer to Earth than satellites, putting them in a sweet spot for services that can't currently be offered by either, executives in charge of solar-aircraft projects say. The planes can capture higher resolution photos or video than satellites, or deliver broadband internet from the air, another thing satellites can't do.

An anonymous reader quotes a report from Ars Technica: Internet service providers are again urging the Federal Communications Commission to impose new fees on Big Tech firms and use the money to subsidize broadband network deployment and affordability programs. If approved, the request would force Big Tech firms to pay into the FCC's Universal Service Fund (USF), which in turn distributes money to broadband providers. The request was made on June 6 by USTelecom, a lobby group for AT&T, Verizon, CenturyLink/Lumen, and smaller telcos. USTelecom has made similar arguments before, but its latest request to the FCC argues that the recent death of a broadband discount program should spur the FCC to start extracting money from Big Tech.

"Through focusing on the Big Tech companies who benefit most from broadband connectivity, the Commission will fairly allocate the burden of sustaining USF," USTelecom wrote in the FCC filing last week. The USF spends about $8 billion a year. Phone companies must pay a percentage of their revenue into the fund, and telcos generally pass those fees on to consumers with a "Universal Service" line item on telephone bills. The money is directed back to the telco industry with programs like the Connect America Fund and Rural Digital Opportunity Fund, which subsidize network construction in unserved and underserved areas. The USF also funds Lifeline program discounts for people with low incomes.

FCC Chairwoman Jessica Rosenworcel hasn't stated any intention to expand USF contributions to Big Tech. Separately, she rejected calls to impose Universal Service fees on broadband, leaving phone service as the only source of USF revenue. The USTelecom filing came in response to the FCC asking for input on its latest analysis of competition in the communications marketplace. USTelecom says the USF is relevant to the proceeding because "the Universal Service Fund is critical for maintaining a competitive marketplace and an expanded contributions base is necessary to sustain the fund." No changes to the USF would be made in this proceeding, though USTelecom's comments could be addressed in the FCC's final report.

Nokia CEO Pekka Lundmark made the world's first phone call using "immersive audio and video" technology, which improves call quality with "three-dimensional" sound. The technology, part of the upcoming 5G Advanced standard, makes interactions more lifelike and is the biggest leap forward in voice calling since monophonic telephony. Nokia aims to license the technology, but widespread availability may take a few years.

Apple has quietly added a Thread radio to nearly all of its newest iPads, MacBooks, and iMacs. The Verge reports: While the company doesn't list Thread on the specs of any of these products, FCC reports indicate that many of Apple's latest devices have had Thread radios tested for compliance. Generally, you don't test a radio that's not there. We found evidence of Thread testing in the following models: iPad Pro 13-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi + Cellular), iPad Pro 11-inch (M4) (Wi-Fi), iPad Air 11-inch (M2) (Wi-Fi + Cellular), iPad Air 13-inch (M2) Wi-Fi, MacBook Air 15-inch (M3), MacBook Pro 14-inch (M3), MacBook Pro 14-inch (M3 Pro or M3 Max), MacBook Pro 16-inch (M3 Pro or M3 Max), iMac (M3, two ports), and iMac (M3, four ports).

The FCC requires manufacturers to list every radio contained in a device and to test them in every possible scenario to make sure they comply with its transmission regulations. Tom Sciorilli, director of certification for Thread Group, told The Verge that the FCC reports reference FCC 15.247, "which confirms the device will essentially 'stay in its lane' and not interfere with other radios when operating." The reports we found are tests of the IEEE 802.15.4 transmitter functionality -- 802.15.4 is the radio standard Thread runs on. While it supports a number of technologies, the reports mention Thread explicitly.

Thread is the primary wireless protocol for the new smart home standard Matter, which Apple helped develop and that is now the underlying architecture for its Apple Home smart home platform. A low-power, low-bandwidth, mesh networking protocol specifically designed for IoT devices, Thread is shown to be faster than Bluetooth and offers better range, making it ideal for connecting products like smart lights, locks, thermostats, and sensors. [...] So why is it there? The Apple Home app runs on Macs and iPads, and Thread radios could allow them to communicate directly with smart home devices and act as Thread border routers. It's possible Apple is planning to turn your Mac or iPad into a home hub, but iPads used to be home hubs, and the company discontinued that capability for its new Apple Home architecture. Those iPads didn't have Thread radios, though.

The Marubo people, an isolated Indigenous tribe in the Amazon, have gained high-speed internet access through Elon Musk's Starlink service, drastically altering their traditional way of life. While the internet has brought significant benefits like improved communication and emergency response, it has also introduced challenges such as social media addiction, exposure to inappropriate content, and cultural erosion. The New York Times reports: After only nine months with Starlink, the Marubo are already grappling with the same challenges that have racked American households for years: teenagers glued to phones; group chats full of gossip; addictive social networks; online strangers; violent video games; scams; misinformation; and minors watching pornography. Modern society has dealt with these issues over decades as the internet continued its relentless march. The Marubo and other Indigenous tribes, who have resisted modernity for generations, are now confronting the internet's potential and peril all at once, while debating what it will mean for their identity and culture.

The internet was an immediate sensation. "It changed the routine so much that it was detrimental," [admitted one Marubo leader, Enoque Marubo]. "In the village, if you don't hunt, fish and plant, you don't eat." Leaders realized they needed limits. The internet would be switched on for only two hours in the morning, five hours in the evening, and all day Sunday. During those windows, many Marubo are crouched over or reclined in hammocks on their phones. They spend lots of time on WhatsApp. There, leaders coordinate between villages and alert the authorities to health issues and environmental destruction. Marubo teachers share lessons with students in different villages. And everyone is in much closer contact with faraway family and friends. To Enoque, the biggest benefit has been in emergencies. A venomous snake bite can require swift rescue by helicopter. Before the internet, the Marubo used amateur radio, relaying a message between several villages to reach the authorities. The internet made such calls instantaneous. "It's already saved lives," he said.

In April, seven months after Starlink's arrival, more than 200 Marubo gathered in a village for meetings. Enoque brought a projector to show a video about bringing Starlink to the villages. As proceedings began, some leaders in the back of the audience spoke up. The internet should be turned off for the meetings, they said. "I don't want people posting in the groups, taking my words out of context," another said. During the meetings, teenagers swiped through Kwai, a Chinese-owned social network. Young boys watched videos of the Brazilian soccer star Neymar Jr. And two 15-year-old girls said they chatted with strangers on Instagram. One said she now dreamed of traveling the world, while the other wants to be a dentist in Sao Paulo. This new window to the outside world had left many in the tribe feeling torn. "Some young people maintain our traditions," said TamaSay Marubo, 42, the tribe's first woman leader. "Others just want to spend the whole afternoon on their phones."

Several broadband industry lobby groups have filed lawsuits against the Federal Communications Commission (FCC) in an attempt to overturn the recently approved net neutrality rules. The regulations, which prohibit blocking, throttling, and paid prioritization, are scheduled to take effect on July 22. The lawsuits were filed in various US appeals courts by groups representing cable, telecom, and mobile Internet service providers, including NCTA-The Internet & Television Association, USTelecom, CTIA-The Wireless Association, and several state-level associations. The groups argue that the FCC lacks the authority to reclassify broadband as a telecommunications service under Title II of the Communications Act of 1934 without explicit instructions from Congress.

In addition to the lawsuits, the industry groups have also petitioned the FCC for a stay of the rules, claiming that their members will suffer irreparable harm if the regulations take effect while litigation is pending. The FCC is expected to reject the petition, but the groups can then seek an injunction from appeals court judges to prevent enforcement. The industry's legal challenge is based on the Supreme Court's evolving approach to the "major questions" doctrine, which limits federal agencies' ability to make decisions on significant issues without clear congressional authorization. However, FCC Commissioner Geoffrey Starks maintains that the agency's authority to regulate broadband as a telecommunications service is "clear as day."

The Ansel Adams estate said it was "officially on our last nerve" after Adobe was caught selling AI-generated images imitating the late photographer's work. The Verge reports: While Adobe permits AI-generated images to be hosted and sold on its stock image platform, users are required to hold the appropriate rights or ownership over the content they upload. Adobe Stock's Contributor Terms specifically prohibits content "created using prompts containing other artist names, or created using prompts otherwise intended to copy another artist." Adobe responded to the callout, saying it had removed the offending content and had privately messaged the Adams estate to get in touch directly in the future. The Adams estate, however, said it had contacted Adobe directly multiple times since August 2023.

"Assuming you want to be taken seriously re: your purported commitment to ethical, responsible AI, while demonstrating respect for the creative community, we invite you to become proactive about complaints like ours, & to stop putting the onus on individual artists/artists' estates to continuously police our IP on your platform, on your terms," said the Adams estate on Threads. "It's past time to stop wasting resources that don't belong to you."

Adobe Stock Vice President Matthew Smith previously told The Verge that the company generally moderates all "crowdsourced" Adobe Stock assets before they are made available to customers, employing a "variety" of methods that include "an experienced team of moderators who review submissions." As of January 2024, Smith said the strongest action the company can take to enforce its platform rules is to block Adobe Stock users who violate them. Bassil Elkadi, Adobe's Director of Communications and Public Relations, told The Verge that Adobe is "actively in touch with Ansel Adams on this matter," and that "appropriate steps were taken given the user violated Stock terms." The Adams estate has since thanked Adobe for removing the images, and said that it expects "it will stick this time." "We don't have a problem with anyone taking inspiration from Ansel's photography," said the Adams estate. "But we strenuously object to the unauthorized use of his name to sell products of any kind, including digital products, and this includes AI-generated output -- regardless of whether his name has been used on the input side, or whether a given model has been trained on his work."

China's Chang'e-6 probe successfully lands on far side of the moon China's moon probe has "successfully touched down on the far side of the moon," CNN reports, in "a significant step for the ambitious mission that could advance the country's aspirations of putting astronauts on the moon" by 2030.

The mission's ultimate goal is to return to Earth the first samples from the moon's far side, CNN reports. And China's lunar lander "is now expected to use a drill and a mechanical arm to gather up to 2 kilograms of moon dust and rocks from the basin, a crater formed some 4 billion years ago." To complete its mission, the lander will need to robotically stow those samples in an ascent vehicle that made the landing with it. The ascent vehicle will then return to lunar orbit, where it will dock with and transfer the samples to a re-entry capsule, according to mission information provided by the China National Space Administration. The re-entry capsule and orbiter will then travel back to Earth's orbit and separate, allowing the re-entry capsule to make its expected return later this month to the Siziwang Banner Landing Site in China's rural Inner Mongolia region.
The mission began with its launch on May 3 — and is expected to last 53 days. The landing marks the second time a mission has successfully reached the far side of the moon. China first completed that historic feat in 2019 with its Chang'e-4 probe... The technically complex mission is made more challenging due to where it is being conducted. The far side of the moon is out of range of normal communications, which means Chang'e-6 must also rely on a satellite that was launched into lunar orbit in March, the Queqiao-2.

Increasingly redundant copper wires may be worth over $7 billion to telecommunications firms, should they take the trouble to recycle them. From a report: The estimate comes from British engineering company TXO, which claims there's up to 800,000 metric tons of copper wiring that could be harvested in the next ten years. TXO claims over a dozen telcos are investigating extracting copper wires from old networks to sell on the open market. The need for copper wiring is declining as carriers adopt fiber optics, which have superior carrying capacity -- one upcoming fiber technology is expected to increase the data capacity of undersea cables by 12 times.

While repurposing old stuff isn't unusual, recycling copper can be particularly valuable as the conductive metal is a crucial material for things like solar panels and batteries, which rely on old-school electrical wiring. A 2022 report from S&P Global estimated demand for copper would double by 2035 -- from 25 million metric tons in 2022 to 50 million -- and since the copper mining industry reportedly won't be able to keep up with demand, that means higher prices. Copper is already 50 percent more expensive since the COVID-19 pandemic, and prices will likely continue to increase.

An anonymous reader quotes a report from The Guardian: The slashing of pollution from shipping in 2020 led to a big "termination shock" that is estimated have pushed the rate of global heating to double the long-term average, according to research. Until 2020, global shipping used dirty, high-sulphur fuels that produced air pollution. The pollution particles blocked sunlight and helped form more clouds, thereby curbing global heating. But new regulations at the start of 2020 slashed the sulphur content of fuels by more than 80%. The new analysis calculates that the subsequent drop in pollution particles has significantly increased the amount of heat being trapped at the Earth's surface that drives the climate crisis. The researchers said the sharp ending of decades of shipping pollution was an inadvertent geoengineering experiment, revealing new information about its effectiveness and risks.

Dr Tianle Yuan, at the University of Maryland, US, who led the study, said the estimated 0.2 watts per sq meter of additional heat trapped over the oceans after the pollution cut was "a big number, and it happened in one year, so it's a big shock to the system." "We will experience about double the warming rate compared to the long-term average" since 1880 as a result, he said. The heating effect of the pollution cut is expected to last about seven years. The research, published in the journal Communications Earth & Environment, combined satellite observations of sulphur pollution and computer modeling to calculate the impact of the cut. It found the short-term shock was equivalent to 80% of the total extra heating the planet has seen since 2020 from longer-term factors such as rising fossil-fuel emissions.

The scientists used relatively simple climate models to estimate how much this would drive up average global temperatures at the surface of the Earth, finding a rise of about 0.16C over seven years. This is a large rise and the same margin by which 2023 beat the temperature record compared with the previous hottest year. However, other scientists think the temperature impact of the pollution cut will be significantly lower due to feedbacks in the climate system, which are included in the most sophisticated climate models. The results of this type of analysis are expected later in 2024. [...] The new analysis indicates that this type of geoengineering would reduce temperatures, but would also bring serious risks. These include the sharp temperature rise when the pumping of aerosols stopped -- the termination shock -- and also potential changes to global precipitation patterns, which could disrupt the monsoon rains that billions of people depend on. "We should definitely do research on this, because it's a tool for situations where we really want to cool down the Earth temporarily," like an emergency brake, said Dr Gavin Schmidt, Director of the NASA Goddard Institute for Space Studies. "But this is not going to be a long-term solution, because it doesn't address the root cause of global warming," which is emissions from fossil fuel burning.

An anonymous reader quotes a report from Reuters: TikTok is working on a clone of its recommendation algorithm for its 170 million U.S. users that may result in a version that operates independently of its Chinese parent and be more palatable to American lawmakers who want to ban it, according to sources with direct knowledge of the efforts. The work on splitting the source code ordered by TikTok's Chinese parent ByteDance late last year predated a bill to force a sale of TikTok's U.S. operations that began gaining steam in Congress this year. The bill was signed into law in April. The sources, who were granted anonymity because they are not authorized to speak publicly about the short-form video sharing app, said that once the code is split, it could lay the groundwork for a divestiture of the U.S. assets, although there are no current plans to do so. The company has previously said it had no plans to sell the U.S. assets and such a move would be impossible. [...]

In the past few months, hundreds of ByteDance and TikTok engineers in both the U.S. and China were ordered to begin separating millions of lines of code, sifting through the company's algorithm that pairs users with videos to their liking. The engineers' mission is to create a separate code base that is independent of systems used by ByteDance's Chinese version of TikTok, Douyin, while eliminating any information linking to Chinese users, two sources with direct knowledge of the project told Reuters. [...] The complexity of the task that the sources described to Reuters as tedious "dirty work" underscores the difficulty of splitting the underlying code that binds TikTok's U.S. operations to its Chinese parent. The work is expected to take over a year to complete, these sources said. [...] At one point, TikTok executives considered open sourcing some of TikTok's algorithm, or making it available to others to access and modify, to demonstrate technological transparency, the sources said.

Executives have communicated plans and provided updates on the code-splitting project during a team all-hands, in internal planning documents and on its internal communications system, called Lark, according to one of the sources who attended the meeting and another source who has viewed the messages. Compliance and legal issues involved with determining what parts of the code can be carried over to TikTok are complicating the work, according to one source. Each line of code has to be reviewed to determine if it can go into the separate code base, the sources added. The goal is to create a new source code repository for a recommendation algorithm serving only TikTok U.S. Once completed, TikTok U.S. will run and maintain its recommendation algorithm independent of TikTok apps in other regions and its Chinese version Douyin. That move would cut it off from the massive engineering development power of its parent company in Beijing, the sources said. If TikTok completes the work to split the recommendation engine from its Chinese counterpart, TikTok management is aware of the risk that TikTok U.S. may not be able to deliver the same level of performance as the existing TikTok because it is heavily reliant on ByteDance's engineers in China to update and maintain the code base to maximize user engagement, sources added.

Satellite-to-phones service provider AST SpaceMobile announced a deal with Verizon to provide remote coverage across the United States. "Verizon's deal effectively includes a $100 million raise for AST, as well, in the form of $65 million in commercial service prepayments and $35 million in debt via convertible notes," reports CNBC. "The companies said that $45 million of the prepayments 'are subject to certain conditions' such as needed regulatory approvals and signing of a definitive commercial agreement." Shares of AST jumped 69% in trading to close at $9.02 a share -- the largest single day rise for the company's stock since it went public in 2021. From the report: AST SpaceMobile is building satellites to provide broadband service to unmodified smartphones, in the nascent "direct-to-device" communications market. [...] The Verizon partnership follows a similar pattern to AT&T's work with AST. Back in January, AT&T was a co-debt investor in the company alongside Google and Vodafone. The companies then established the commercial agreement earlier this month, which "lays out in much more detail how we will ultimately offer service together," AST's Chief Strategy Officer Scott Wisniewski said in a statement to CNBC. [...] AST expects to launch its first five commercial satellites later this year.

An anonymous reader quotes an op-ed from The Globe and Mail, written by Kate Robertson and Ron Deibert. Robertson is a senior research associate and Deibert is director at the University of Toronto's Citizen Lab. From the piece: A federal cybersecurity bill, slated to advance through Parliament soon, contains secretive, encryption-breaking powers that the government has been loath to talk about. And they threaten the online security of everyone in Canada. Bill C-26 empowers government officials to secretly order telecommunications companies to install backdoors inside encrypted elements in Canada's networks. This could include requiring telcos to alter the 5G encryption standards that protect mobile communications to facilitate government surveillance. The government's decision to push the proposed law forward without amending it to remove this encryption-breaking capability has set off alarm bells that these new powers are a feature, not a bug.

There are already many insecurities in today's networks, reaching down to the infrastructure layers of communication technology. The Signalling System No. 7, developed in 1975 to route phone calls, has become a major source of insecurity for cellphones. In 2017, the CBC demonstrated how hackers only needed a Canadian MP's cell number to intercept his movements, text messages and phone calls. Little has changed since: A 2023 Citizen Lab report details pervasive vulnerabilities at the heart of the world's mobile networks. So it makes no sense that the Canadian government would itself seek the ability to create more holes, rather than patching them. Yet it is pushing for potential new powers that would infect next-generation cybersecurity tools with old diseases.

It's not as if the government wasn't warned. Citizen Lab researchers presented the 2023 report's findings in parliamentary hearings on Bill C-26, and leaders and experts in civil society and in Canada's telecommunications industry warned that the bill must be narrowed to prevent its broad powers to compel technical changes from being used to compromise the "confidentiality, integrity, or availability" of telecommunication services. And yet, while government MPs maintained that their intent is not to expand surveillance capabilities, MPs pushed the bill out of committee without this critical amendment last month. In doing so, the government has set itself up to be the sole arbiter of when, and on what conditions, Canadians deserve security for their most confidential communications -- personal, business, religious, or otherwise. The new powers would only make people in Canada more vulnerable to malicious threats to the privacy and security of all network users, including Canada's most senior officials. [...] "Now, more than ever, there is no such thing as a safe backdoor," the authors write in closing. "A shortcut that provides a narrow advantage for the few at the expense of us all is no way to secure our complex digital ecosystem."

"Against this threat landscape, a pivot is crucial. Canada needs cybersecurity laws that explicitly recognize that uncompromised encryption is the backbone of cybersecurity, and it must be mandated and protected by all means possible."

A new tool called Lifeseeker could help search and rescue teams find missing people in minutes using their cellphones. The technology acts as a miniature cellphone tower, allowing rescuers to pinpoint cellphone locations within a 3-mile radius, significantly improving the efficiency and success rate of search missions in challenging terrains. The Colorado Sun reports: "As we detect the phone, basically a blotch shows up on the map and as we fly around that area, that blotch gets smaller and smaller and smaller until we can see exactly where they are," said Dr. Tim Durkin, a search and rescue program coordinator for Colorado Highland Helicopters. "That process of detecting, focusing on one specific location takes about a minute -- not really very long at all." Depending on the situation, search and rescue teams can then send in ground crews with the person's location or land the helicopter if there's a clearing nearby and conditions allow for a safe landing, Durkin said. During a test mission in La Plata Canyon northwest of Durango, search crews found the two people they were looking for within two minutes and 14 seconds, Durkin said.

The technology, called Lifeseeker, was developed by Spain-based company CENTUM research & technology and is in the process of being approved by the Federal Communications Commission before it can be sold to the state or counties hoping to use it for their SAR efforts, he said. [...] The radio-based technology needs a clear view of the terrain without interference to pick up the signal of the cellphone. If the conditions and terrain are favorable, it can detect a cellphone up to nearly 20 miles away. It takes about three minutes to attach the Lifeseeker unit inside a helicopter when needed for a search and rescue mission, Durkin said. SAR can also use the tool to send text messages to the missing person, for example, advising them to stay in one area if they are hurt or move to a clearing for a helicopter to pick them up. The tool also has a broadcast function that allows SAR to send out a message to a group of people within a certain range, similar to an Amber Alert for a missing child, to warn them of a wildfire or flood, Durkin said.

An anonymous reader quotes a report from the BBC: A sophisticated joint European-Japanese satellite has launched to measure how clouds influence the climate. Some low-level clouds are known to cool the planet, others at high altitude will act as a blanket. The Earthcare mission will use a laser and a radar to probe the atmosphere to see precisely where the balance lies. It's one of the great uncertainties in the computer models used to forecast how the climate will respond to increasing levels of greenhouse gases. "Many of our models suggest cloud cover will go down in the future and that means that clouds will reflect less sunlight back to space, more will be absorbed at the surface and that will act as an amplifier to the warming we would get from carbon dioxide," Dr Robin Hogan, from the European Centre for Medium-Range Weather Forecasts, told BBC News.

The 2.3-tonne satellite was sent up from California on a SpaceX rocket. The project is led by the European Space Agency (ESA), which has described it as the organization's most complex Earth observation venture to date. Certainly, the technical challenge in getting the instruments to work as intended has been immense. It's taken fully 20 years to go from mission approval to launch. Earthcare will circle the Earth at a height of about 400km (250 miles). It's actually got four instruments in total that will work in unison to get at the information sought by climate scientists.

The simplest is an imager -- a camera that will take pictures of the scene passing below the spacecraft to give context to the measurements made by the other three instruments. Earthcare's European ultraviolet laser will see the thin, high clouds and the tops of clouds lower down. It will also detect the small particles and droplets (aerosols) in the atmosphere that influence the formation and behavior of clouds. The Japanese radar will look into the clouds, to determine how much water they are carrying and how that's precipitating as rain, hail and snow. And a radiometer will sense how much of the energy falling on to Earth from the Sun is being reflected or radiated back into space.

An anonymous reader quotes a report from the New York Times: The defense lawyer minced no words as he addressed a room full of plastic-industry executives. Prepare for a wave of lawsuits with potentially "astronomical" costs. Speaking at a conference earlier this year, the lawyer, Brian Gross, said the coming litigation could "dwarf anything related to asbestos," one of the most sprawling corporate-liability battles in United States history. Mr. Gross was referring to PFAS, the "forever chemicals" that have emerged as one of the major pollution issues of our time. Used for decades in countless everyday objects -- cosmetics, takeout containers, frying pans -- PFAS have been linked to serious health risks including cancer. Last month the federal government said several types of PFAS must be removed from the drinking water of hundreds of millions of Americans. "Do what you can, while you can, before you get sued," Mr. Gross said at the February session, according to a recording of the event made by a participant and examined by The New York Times. "Review any marketing materials or other communications that you've had with your customers, with your suppliers, see whether there's anything in those documents that's problematic to your defense," he said. "Weed out people and find the right witness to represent your company."

A wide swath of the chemicals, plastics and related industries are gearing up to fight a surge in litigation related to PFAS, or per- and polyfluoroalkyl substances, a class of nearly 15,000 versatile synthetic chemicals linked to serious health problems. [...] PFAS-related lawsuits have already targeted manufacturers in the United States, including DuPont, its spinoff Chemours, and 3M. Last year, 3M agreed to pay at least $10 billion to water utilities across the United States that had sought compensation for cleanup costs. Thirty state attorneys general have also sued PFAS manufacturers, accusing the manufacturers of widespread contamination. But experts say the legal battle is just beginning. Under increasing scrutiny are a wider universe of companies that use PFAS in their products. This month, plaintiffs filed a class-action lawsuit against Bic, accusing the razor company for failing to disclose that some of its razors contained PFAS. Bic said it doesn't comment on pending litigation, and said it had a longstanding commitment to safety.

The Biden administration has moved to regulate the chemicals, for the first time requiring municipal water systems to remove six types of PFAS. Last month, the Environmental Protection Agency also designated two of those PFAS chemicals as hazardous substances under the Superfund law, shifting responsibility for their cleanup at contaminated sites from taxpayers to polluters. Both rules are expected to prompt a new round of litigation from water utilities, local communities and others suing for cleanup costs. "To say that the floodgates are opening is an understatement," said Emily M. Lamond, an attorney who focuses on environmental litigation at the law firm Cole Schotz. "Take tobacco, asbestos, MTBE, combine them, and I think we're still going to see more PFAS-related litigation," she said, referring to methyl tert-butyl ether, a former harmful gasoline additive that contaminated drinking water. Together, the trio led to claims totaling hundreds of billions of dollars. Unlike tobacco, used by only a subset of the public, "pretty much every one of us in the United States is walking around with PFAS in our bodies," said Erik Olson, senior strategic director for environmental health at the Natural Resources Defense Council. "And we're being exposed without our knowledge or consent, often by industries that knew how dangerous the chemicals were, and failed to disclose that," he said. "That's a formula for really significant liability."

T-Mobile said Tuesday that it plans to acquire most of U.S. Cellular, including stores, some of the wireless operator's spectrum and its customers, in a deal worth $4.4 billion.

However, the organization confirmed that its member database contains some private information, including names, addresses, and call signs. While they do not specifically state email addresses are stored in the database, one is required to become a member of the organization.
"The ARRL has not specifically said that its member database has been accessed by hackers," Security Week points out, "but its statement suggests it's possible."

The site adds that it has also "reached out to ARRL to find out if this was a ransomware attack and whether the attackers made any ransom demand."

Messaging app Signal's president Meredith Whittaker criticized rival Telegram's security on Friday, saying Telegram founder Pavel Durov is "full of s---" in his claims about Signal. "Telegram is a social media platform, it's not encrypted, it's the least secure of messaging and social media services out there," Whittaker told TechCrunch in an interview. The comments come amid a war of words between Whittaker, Durov and Twitter owner Elon Musk over the security of their respective platforms. Whittaker said Durov's amplification of claims questioning Signal's security was "incredibly reckless" and "actually harms real people."

"Play your games, but don't take them into my court," Whittaker said, accusing Durov of prioritizing being "followed by a professional photographer" over getting facts right about Signal's encryption. Signal uses end-to-end encryption by default, while Telegram only offers it for "secret chats." Whittaker said many in Ukraine and Russia use Signal for "actual serious communications" while relying on Telegram's less-secure social media features. She said the "jury is in" on the platforms' comparative security and that Signal's open source code allows experts to validate its privacy claims, which have the trust of the security community.
