An anonymous reader quotes a report from the Associated Press: The U.S. military used a laser Thursday to shoot down a "seemingly threatening" drone flying near the U.S.-Mexico border. It turned out the drone belonged to Customs and Border Protection, lawmakers said. The case of mistaken identity prompted the Federal Aviation Administration to close additional airspace around Fort Hancock, about 50 miles (80 kilometers) southeast of El Paso. The military is required to formally notify the FAA when it takes any counter-drone action inside U.S. airspace.

It was the second time in two weeks that a laser was fired in the area. The last time it was CBP that used the weapon and nothing was hit. That incident occurred near Fort Bliss and prompted the FAA to shut down air traffic at El Paso airport and the surrounding area. This time, the closure was smaller and commercial flights were not affected. The FAA, CBP and the Pentagon confirmed the incident in a joint statement, saying the military "employed counter-unmanned aircraft system authorities to mitigate a seemingly threatening unmanned aerial system operating within military airspace."

"At President Trump's direction, the Department of War, FAA, and Customs and Border Patrol are working together in an unprecedented fashion to mitigate drone threats by Mexican cartels and foreign terrorist organizations at the U.S.-Mexico Border," the statement said. The report notes that 27,000 drones were detected within 1,600 feet of the southern border in the last six months of 2024.

Illinois Democratic U.S. Sen. Tammy Duckworth, the ranking member on the Senate's Aviation Subcommittee, is calling for an independent investigation to look into the matter. "The Trump administration's incompetence continues to cause chaos in our skies," Duckworth said.

An anonymous reader shares a report: In its 250th year, is America, land of immigration, becoming a country of emigration? Last year the U.S. experienced something that hasn't definitively occurred since the Great Depression: More people moved out than moved in. The Trump administration has hailed the exodus -- negative net migration -- as the fulfillment of its promise to ramp up deportations and restrict new visas. Beneath the stormy optics of that immigration crackdown, however, lies a less-noticed reversal: America's own citizens are leaving in record numbers, replanting themselves and their families in lands they find more affordable and safe.

Since the Eisenhower administration, the U.S. hasn't collected comprehensive statistics on the number of citizens leaving. Yet data on residence permits, foreign home purchases, student enrollments and other metrics from more than 50 countries show that Americans are voting with their feet to an unprecedented degree. A millions-strong diaspora is studying, telecommuting and retiring overseas. The new American dream, for some of its citizens, is to no longer live there.

In the cobblestoned streets of Lisbon, so many Americans are snapping up apartments that the newest arrivals complain they mostly hear their own language -- not Portuguese. One of every 15 residents in Dublin's trendy Grand Canal Dock district was born in the U.S., according to realtors, higher than the percentage of Americans born in Ireland during the 19th-century influx following the Potato Famine. In Bali, Colombia and Thailand, the strains of housing American remote workers paid in dollars have inspired locals to mount protests against a wave of gentrification. More than 100,000 young students are enrolled abroad for a more affordable university degree. In nursing homes mushrooming across the Mexican border, elderly Americans are turning up for low-cost care.

[...] The U.S. experienced net negative migration -- an estimated loss of some 150,000 people -- in 2025, and the outflow will likely increase in 2026, according to calculations by the Brookings Institution, a public-policy think tank. The number could be larger or smaller because official U.S. data doesn't yet fully capture the number of people leaving, Brookings analysts noted. The total in-migration was between around 2.6 and 2.7 million in 2025, down from a peak of almost 6 million in 2023. The U.S. saw 675,000 deportations and 2.2 million "self-deportations" last year, according to data from the Department of Homeland Security. A Wall Street Journal analysis of 15 countries providing full or partial 2025 data showed that at least 180,000 Americans joined them -- a number likely to be far higher when other countries report full statistics.

A hacker exploited Anthropic's AI chatbot to carry out a series of attacks against Mexican government agencies, resulting in the theft of a huge trove of sensitive tax and voter information, according to cybersecurity researchers. From a report: The unknown Claude user wrote Spanish-language prompts for the chatbot to act as an elite hacker, finding vulnerabilities in government networks, writing computer scripts to exploit them and determining ways to automate data theft, Israeli cybersecurity startup Gambit Security said in research published Wednesday.

The activity started in December and continued for roughly a month. In all, 150 gigabytes of Mexican government data was stolen, including documents related to 195 million taxpayer records as well as voter records, government employee credentials and civil registry files, according to the researchers.

An anonymous reader shares a report: The abrupt closure of El Paso's airspace late Tuesday was precipitated when Customs and Border Protection officials deployed an anti-drone laser on loan from the Department of Defense without giving aviation officials enough time to assess the risks to commercial aircraft, according to multiple people briefed on the situation.

The episode led the Federal Aviation Administration to abruptly declare that the nearby airspace would be shut down for 10 days, an extraordinary pause that was quickly lifted Wednesday morning at the direction of the White House. Top administration officials quickly claimed that the closure was in response to a sudden incursion of drones from Mexican drug cartels that required a military response, with Transportation Secretary Sean Duffy declaring in a social media post that "the threat has been neutralized."

But that assertion was undercut by multiple people familiar with the situation, who said that the F.A.A.'s extreme move came after immigration officials earlier this week used an anti-drone laser shared by the Pentagon without coordination with the F.A.A. The people spoke on the condition of anonymity because they were not authorized to speak publicly. C.B.P. officials thought they were firing on a cartel drone, the people said, but it turned out to be a party balloon. Defense Department officials were present during the incident, one person said.

The restaurant industry is trying to figure out whether America has hit peak pizza. From a report: Once the second-most common U.S. restaurant type, pizzerias are now outnumbered by coffee shops and Mexican food eateries, according to industry data. Sales growth at pizza restaurants has lagged behind the broader fast-food market for years, and the outlook ahead isn't much brighter.

"Pizza is disrupted right now," Ravi Thanawala, chief financial officer and North America president at Papa John's International, said in an interview. "That's what the consumer tells us." The parent of the Pieology Pizzeria chain filed for chapter 11 bankruptcy protection in December. Others, including the parent of Anthony's Coal Fired Pizza & Wings and Bertucci's Brick Oven Pizza & Pasta, earlier filed for bankruptcy.

Pizza once was a novelty outside big U.S. cities, providing room for growth for independent shops and then chains such as Pizza Hut with its red roof dine-in restaurants. Purpose-made cardboard boxes and fleets of delivery drivers helped make pizza a takeout staple for those seeking low-stress meals. Today, pizza shops are engaged in price wars with one another and other kinds of fast food. Food-delivery apps have put a wider range of cuisines and options at Americans' fingertips. And $20 a pie for a family can feel expensive compared with $5 fast-food deals, frozen pizzas or eating a home-cooked meal.

[...] Pizza's dominance in American restaurant fare is declining, however. Among different cuisines, it ranked sixth in terms of U.S. sales in 2024 among restaurant chains, down from second place during the 1990s, Technomic said. The number of pizza restaurants in the U.S. hit a record high in 2019 and has declined since then, figures from the market-research firm Datassential show.

Amazon's data-center expansion turned Umatilla, Oregon into an unlikely nerve center for American infrastructure investment. The community of roughly 8,000 residents has seen home prices double and local government budgets surge from $7 million in 2011 to a hundred and $44 million in the past fiscal year. Yesenia Leon-Tejeda, a Realtor and daughter of Mexican-born farmhands who once worked 12-hour shifts at a distribution center, is now on pace to close 35 deals this year.

Federal data shows investment in software and information-processing equipment drove most of America's GDP growth in the first half of 2025. Goldman Sachs estimated that roughly 72% of all server-farm capacity sat in just 1% of counties as of July. The region's hydroelectric dams and cheap power attracted Amazon Web Services more than a decade ago. Growth has brought rising costs for housing and child care. Political tensions over spending erupted this year when Mayor Caden Sipe sued the city manager and council members.

"A new study published on Monday found that communications from cellphone carriers, retailers, banks, and even militaries are being broadcast unencrypted through geostationary satellites..." reports Gizmodo. "The team obtained unencrypted internet communications from U.S. military sea vessels and even communications regarding narcotics trafficking from Mexican military and law enforcement." Researchers from the University of California, San Diego (UCSD) and the University of Maryland scanned 39 of these satellites from a rooftop in Southern California over three years. They found that roughly half of the signals they analyzed were transmitting unencrypted data, potentially exposing everything from phone calls and military logistics to a retail chain's inventory. "There is a clear mismatch between how satellite customers expect data to be secured and how it is secured in practice," the researchers wrote in their paper titled "Don't Look Up: There Are Sensitive Internal Links in the Clear on GEO Satellites...." "They assumed that no one was ever going to check and scan all these satellites and see what was out there. That was their method of security," Aaron Schulman, a UCSD professor and co-lead of the study, told Wired....

Even more surprisingly, the researchers didn't need any fancy spy gear to collect this data. Their setup used only off-the-shelf hardware, including a $185 satellite dish, a $140 roof mount with a $195 motor, and a $230 tuner card. Altogether, the system cost roughly $750 and was installed on a university building in La Jolla, San Diego.

With their simple setup, the researchers were able to collect a wide range of communication data, including phone calls, texts, in-flight Wi-Fi data from airline passengers, and signals from electric utilities. They even obtained U.S. and Mexican military and law enforcement communications, as well as ATM transactions and corporate communications... When it came to telecoms, specifically, the team collected phone numbers, calls, and texts from customers of T-Mobile, AT&T Mexico, and Telmex... It only took the team nine hours to collect the phone numbers of over 2,700 T-Mobile users, along with some of their calls and text messages.
T-Mobile told Gizmodo the lack of encryption was "a vendor's technical misconfiguration" affecting "a limited number of cell sites" and was "not network-wide... [W]e implemented nationwide Session Initiation Protocol (SIP) encryption for all customers to further protect signaling traffic as it travels between mobile handsets and the network core, including call set up, numbers dialed and text message content. We appreciate our collaboration with the security research community, whose work helps reinforce our ongoing commitment to protecting customer data and enhances security across the industry."

Indeed, the researchers write that "Each time we discovered sensitive information in our data, we went through considerable effort to determine the responsible party, establish contact, and disclose the vulnerability. In several cases, the responsible party told us that they had deployed a remedy. For the following parties, we re-scanned with their permission and were able to verify a remedy had been deployed: T-Mobile, WalMart, and KPU."

The researchers acknowledge that exposure "was limited to a relatively small number of cell towers in specific remote areas."

Researchers at UC San Diego and the University of Maryland have found that roughly half of geostationary satellite signals transmit sensitive data without encryption. The team spent three years using an $800 satellite receiver on a university rooftop in San Diego to intercept communications from satellites visible from their location. They collected phone calls and text messages from more than 2,700 T-Mobile users in just nine hours of recording.

The researchers also obtained data from airline passengers using in-flight Wi-Fi, communications from electric utilities and offshore oil and gas platforms, and US and Mexican military communications that revealed personnel locations and equipment details. The exposed data resulted from telecommunications companies using satellites to relay signals from remote cell towers to their core networks.

The researchers examined only about 15% of global satellite transponder communications and presented their findings at an Association for Computing Machinery conference in Taiwan this week. Most companies warned by the researchers have encrypted their satellite transmissions, but some US critical infrastructure owners have not yet added encryption.

Mexico has filed a lawsuit against Google for changing the name of the Gulf of Mexico to "Gulf of America" for U.S. users on Google Maps, following a Republican-led House vote on Thursday to codify the name change. President Claudia Sheinbaum argues the U.S. only has authority to rename its portion of the continental shelf and warned of legal action unless Google reversed the change. The Guardian reports: "All we want is for the decree issued by the US government to be complied with," Sheinbaum said. "The US government only calls the portion of the US continental shelf the Gulf of America, not the entire gulf, because it wouldn't have the authority to name the entire gulf," she added. In response to Trump, Sheinbaum has cheekily suggested calling the United States "America Mexicana" -- Mexican America, pointing to a map dating back to before 1848, when one-third of her country was seized by the United States.

Mexico has threatened legal action against Google after the tech company refused to fully restore the name Gulf of Mexico on its mapping service, escalating a dispute sparked by U.S. President Donald Trump's move to rename the body of water. Google Maps currently displays the water body as Gulf of America within U.S. territory, Gulf of Mexico within Mexican borders, and Gulf of Mexico (Gulf of America) elsewhere, according to a letter from Google vice president Cris Turner to Mexican President Claudia Sheinbaum.

Mexico argues the policy violates its sovereignty since the U.S. controls only 46% of the gulf, while Mexico and Cuba control 49% and 5% respectively. The historic name Gulf of Mexico, dating to 1607, is recognized by the United Nations. The dispute has strained U.S.-Mexico relations, with the White House barring Associated Press reporters from events over the news agency's naming policy.

"The Chinese government has long subsidized carmakers with the goal of becoming a major auto exporter," notes the New York Times. But this week they reported on dozens of dealerships around Mexico that are now selling China-made electric vehicles, saying it could be "a potentially grave threat to the North American auto industry."

One employee said their dealership "was selling cars as fast as they arrived from China," including "a small but capable four-door electric compact that costs about $18,000." Chinese carmakers are effectively barred from the United States by tariffs that double the sticker price of vehicles imported from China, and they are not yet manufacturing significant numbers of vehicles in Mexico that could be exported across the border. But their ambition to expand overseas is on vivid display in Mexico and across Latin America, Asia, Europe and Africa. Ads for Chinese brands are in airports and soccer stadiums and loom above Mexico City streets on large billboards. Chinese cars, both gasoline and electric models, are an increasingly common sight. BYD and others are also looking for places to build factories in Mexico, although none have announced firm plans. Initially, the plants would serve Latin America, part of a campaign by Chinese automakers to erode the dominance of Japanese, American and European carmakers in places like Brazil and Thailand.

But there is little doubt that, eventually, Chinese carmakers hope to use Mexico as an on-ramp to the United States.
One of Mexico's EV dealers suggested to the Times that "maybe next year BYD can enter the United States." And he added with a smile, "If not, I can deliver." It is very unlikely that the Dolphin or any other Chinese car brand will be available in the United States soon. Because of the high tariffs, Chinese carmakers have not tried to establish dealerships or get approval from federal regulators to sell in the United States. (BYD does make electric buses in California.) And someone buying a BYD from a Mexican dealer like Mr. Alegría would have a hard time registering and insuring it in the United States because the cars have not demonstrated that they meet safety standards... But in the years to come it may be difficult to explain to consumers in the United States why they're not allowed to buy inexpensive electric vehicles that are readily available across the border, especially if they're made in Mexico, which already manufactures millions of cars for the United States.

Less than 20 years ago, Chinese cars were widely seen as inferior, even by many Chinese drivers. But in recent years, the country's manufacturers have pulled even with foreign rivals in mechanical quality, analysts say, and often surpass U.S., Japanese and European carmakers in battery technology, autonomous driving and entertainment software. (Think in-car karaoke and rotating touch screens)... [T]he auto industry does not appear to have seen anything like the current wave of Chinese brands, which have quickly overtaken Japanese companies as the world's largest auto exporters. Chinese carmakers have made deep inroads in countries where they have local production or face few significant trade barriers. In Brazil, Chinese brands have a 9 percent share of car sales, up from 1 percent in 2019. In Thailand, they have 18 percent of the market, up from 5 percent in 2019, according to JATO.
The article notes that for the world's largest car market — China itself — General Motors just announced "a more than $5 billion hit to its profit" to restructure China operations that have been losing money in recent years. And the article includes this quote from Felipe Munoz, global analyst at the research firm JATO Dynamics.

"Before the pandemic, the rules were set down by the Western carmakers. Now it's the opposite."

schwit1 writes: Recruiters approach students with tempting offers, often after observing them for weeks. Promising salaries of over $800 per month -- double the average pay for chemists in Mexican companies, along with potential bonuses like cars or housing -- recruiters capitalize on the financial struggles of young professionals.

These "cooks" are tasked with improving fentanyl's addictive quality and finding alternative synthesis methods to mitigate supply chain disruptions caused by stricter chemical export controls from China and pandemic-induced bottlenecks. The Times interviewed seven drug "cooks," three university chemistry students recruited by the Sinaloa cartel, two agents, a recruiter, and a university professor -- all anonymously to avoid cartel retaliation. According to the recruiter, candidates must be passionate, discreet, and indifferent to the ethical consequences of their work.

The university professor highlighted a disturbing trend: students openly expressed interest in synthesizing illicit drugs during lectures.

As the moon blocked the view of the sun across parts of Mexico, the United States and Canada on Monday, the celestial event managed another magnificent feat: It got people offline. From a report: According to Cloudflare, a cloud-computing service used by about 20 percent of websites globally, internet traffic dipped along the path of totality as spellbound viewers took a break from their phones and computers to catch a glimpse of the real-life spectacle.

The places with the most dramatic views saw the biggest dips in traffic compared with the previous week. In Vermont, Arkansas, Indiana, Maine, New Hampshire and Ohio -- states that were in the path of totality, meaning the moon completely blocked out the sun -- internet traffic dropped by 40 percent to 60 percent around the time of the eclipse, Cloudflare said. States that had partial views also saw drops in internet activity, but to a much lesser extent. At 3:25 p.m. Eastern time, internet traffic in New York dropped by 29 percent compared with the previous week, Cloudflare found.

The path of totality made up a roughly 110-mile-wide belt that stretched from Mazatlan, Mexico, to Montreal. In the Mexican state of Durango, which was in the eclipse zone, internet traffic measured by Cloudflare dipped 57 percent compared with the previous week, while farther south, in Mexico City, traffic was down 22 percent. The duration of the eclipse's totality varied by location, with some places experiencing it for more than four minutes while for others, it was just one to two minutes.

Fast Company notes that "the deadly impacts of Pegasus and other cyberweapons — wielded by governments from Spain to Saudi Arabia against human rights defenders, journalists, lawyers and others — is by now well documented. A wave of scrutiny and sanctions have helped expose the secretive, quasi-legal industry behind these tools, and put financial strain on firms like Israel's NSO Group, which builds Pegasus.

"And yet business is booming." New research published this month by Google and Meta suggest that despite new restrictions, the cyberattack market is growing, and growing more dangerous, aiding government violence and repression and eroding democracy around the globe.

"The industry is thriving," says Maddie Stone, a researcher at Google's Threat Analysis Group (TAG) who hunts zero-day exploits, the software bugs that have yet to be fixed and are worth potentially hundreds of millions to spyware sellers. "More companies keep popping up, and their government customers are determined to buy from them, and want these capabilities, and are using them." For the first time, half of known zero-days against Google and Android products now come from private companies, according to a report published this month by Stone's team at Google. Beyond prominent firms like NSO and Candiru, Google's researchers say they are tracking about 40 companies involved in the creation of hacking tools that have been deployed against "high risk individuals."

Of the 72 zero-day exploits Google discovered in the wild between 2014 and last year, 35 were attributed to these and other industry players, as opposed to state-backed actors. "If governments ever had a monopoly on the most sophisticated capabilities, that era is certainly over," reads the report.

The Google findings and a spyware-focused threat report published by Meta a week later reflect an increasingly tough response by Big Tech to an industry that profits from breaking into its systems. The reports also put new pressure on the US and others to take action against the mostly unregulated industry.
"In its report, Google describes a 'rise in turnkey espionage solutions' offered by dozens of shady companies..."

A cartel in the embattled central Mexico state of Michoacan set up its own makeshift internet antennas and told locals they had to pay to use its wifi service or they would be killed, according to prosecutors. New submitter awwshit shares a story: Dubbed "narco-antennas" by local media, the cartel's system involved internet antennas set up in various towns built with stolen equipment. The group charged approximately 5,000 people elevated prices between 400 and 500 pesos ($25 and $30) a month, the Michoacan state prosecutor's office told the Associated Press. That meant the group could rake in about $150,000 a month. People were terrorized "to contract the internet services at excessive costs, under the claim that they would be killed if they did not," prosecutors said, though they did not report any such deaths. Local media identified the criminal group as a faction known as Los Viagras. Prosecutors declined to say which cartel was involved because the case was still under investigation, but they confirmed Los Viagras dominates the towns forced to make the wifi payments.

Long-time Slashdot reader Alain Williams writes: Apple co-founder Steve Wozniak is in the hospital in Mexico, according to multiple reports.

It is not currently clear what the cause is. The 73-year-old was in Mexico City attending the World Business Forum (WBF), a business conference. [According to TMZ, Wozniak finished his speech but then told his wife he was "feeling strange." She reportedly insisted he go to the hospital.] An unnamed source from the WBF said that Mr Wozniak fainted on Wednesday at the event [minutes before his participation], according to CNN. TMZ reports that Wozniak was hospitalized after "suffering what appears to be vertigo." Mexican media outlets were reporting that it was due to a possible stroke.

A journalist and researcher on unidentified anomalous phenomena (UAP), or UFOs as they're better known, presented the remains of purported "non-human" beings to lawmakers in Mexico on Tuesday during the country's first public congressional hearing on the topic. From a report: Jamie Maussan brought two boxes containing what he said were the small, stuffed bodies of extraterrestrials recovered in Peru in 2017. He said carbon-14 dating carried out by the National Autonomous University of Mexico had determined the remains were 700 and 1,800 years old. Each of the figures has only three fingers on each hand and elongated heads, resembling, at least superficially, the Hollywood-born character ET.

"This is the first time it (extraterrestrial life) is presented in such a form and I think there is a clear demonstration that we are dealing with non-human specimens that are not related to any other species in our world," Maussan told the lawmakers, urging them to consider the topic, which he said should not be viewed as "a political topic -- it's a topic for humanity." He said DNA evidence could prove the specimens were not of this planet, but it wasn't clear if any such tests had been carried out. At least one previous claim by Maussan about purported "non-human" remains discovered in Peru has been debunked, though the specimens he presented Tuesday in Mexico City appeared different to the one he previously spoke about in 2015.

An anonymous reader quotes a report from Axios: Mexico is debating shortening its workweek from 48 hours to 40, but not everyone is on board. The Mexican bill made it out of committee last week, and it likely has the votes to pass when the legislative session restarts in September. In Mexico, cutting the workweek from the current 48 hours would give workers an extra day off per week. More than 40% of Mexicans (PDF) work six days a week, according to the national statistics institute.

"We want workers here to work to live, not live to work," Mexican Congress Member Susana Prieto Terrazas, who introduced the proposal, told Noticias Telemundo this week. "A lot of people work 10 or 12 hours daily and on top of that they take up to four hours going to work and back home That's not life," she added. Prieto Terrazas dismissed concerns about the law's possible immediate application, saying companies have months to become familiar with the draft and make preparations before the congressional vote. The bill comes as other countries push to adopt a four-day workweek. "The vast majority of companies taking part in the world's largest trial of a four-day week have opted to continue with the new working pattern, in a result hailed as evidence that it could work across the UK economy," reported The Guardian in March of this year.

"Of the 61 companies that entered the six-month trial, 56 have extended the four-day week, including 18 who have made it permanent."

An anonymous reader quotes a report from Reuters: The founder of WallStreetBets, which has been credited with helping ignite investors' frenzy into "meme" stocks, sued Reddit on Wednesday, accusing it of wrongly banning him from moderating the community and undermining his trademark rights. Jaime Rogozinski said his ouster, ostensibly for violating Reddit policy by "attempting to monetize a community," was a pretext to keep him from trying to control "a famous brand that helped Reddit rise to a $10 billion valuation" by late 2021.

According to the complaint filed in federal court in Oakland, California, Rogozinski applied to trademark "WallStreetBets" in March 2020, one month before his ouster, when the community reached 1 million subscribers. Founded in 2012, the community now has 13.6 million subscribers. "If you build it, they will come," the complaint said, quoting from the 1989 movie "Field of Dreams. "Reddit's dreams, however, turned out to be Mr. Rogozinski's nightmare as the company insists, 'if you build it, we will take it from you.'" Rogozinski said he is a dual U.S.-Mexican citizen, and lives in Mexico City. He is seeking at least $1 million in damages for breach of contract and violations of his publicity rights, and a ban on Reddit's use of WallStreetBets unless it reinstates him as senior moderator of the r/WallStreetBets subreddit. Reddit rejected Rogozinski's claims. "This is a completely frivolous lawsuit with no basis in reality," a spokeswoman said. "Jamie was removed as a moderator of r/WallStreetBets by Reddit and banned by the community moderators for attempting to enrich himself. This lawsuit is another transparent attempt to enrich himself."

An anonymous reader shares a report: The tiny startup Make Sunsets, which had been experimenting with releasing sulfur dioxide into the atmosphere to reflect sunlight in order to cool the earth, said Wednesday it would cease operations for the time being and review its approach after the Mexican government cracked down on solar geoengineering. The idea of releasing aerosols into the atmosphere to cool the earth has been around since the 1960's, but it had largely been relegated to science fiction until recently, as the urgency of climate change has become more apparent. The White House is currently coordinating a five-year research plan to study the idea, which is colloquially known as "solar geoengineering," and the quadrennial U.N.-backed Montreal Protocol assessment report for the first time included an entire chapter it.

Luke Iseman, a serial inventor and the former director of hardware at Y Combinator, believed all of that research was not happening fast enough. So he started tinkering with releasing sulfur dioxide particles into the atmosphere with balloons, raised venture capital to fund the startup, and brought on co-founder Andrew Song to manage sales. Make Sunsets was planning to launch three latex weather balloons that would release anywhere between 10 and 500 grams of sulfur dioxide in January. But many industry watchers criticized its plans for being hasty and lacking sophistication. On Friday, the government of Mexico issued a statement that it plans to "prohibit and, where appropriate, stop experimentation practices with solar geoengineering in the country."
