Huawei's newest laptop runs on a chip made by Taiwan Semiconductor Manufacturing Co., a teardown of the device showed, quashing talk of another Chinese technological breakthrough. From a report: The Qingyun L540 notebook contains a 5-nanometer chip made by the Taiwanese company in 2020, around the time US sanctions cut off Huawei's access to the chipmaker, research firm TechInsights found after dismantling the device for Bloomberg News. That counters speculation that Huawei's mainland Chinese chipmaking partner, Semiconductor Manufacturing International Corp., may have achieved a major leap in fabrication technique.

Huawei caused a stir in the US and China last August when it released a smartphone with a 7nm processor made by Shanghai-based SMIC. A teardown by the Canada-based research outfit for Bloomberg News showed the Mate 60 Pro's chip was only a few years behind the cutting edge, a feat that US trade curbs were meant to prevent. That revelation spurred celebration across the Chinese tech scene, and a debate in the US about the effectiveness of sanctions.

The Food and Drug Administration has allowed Florida to import millions of dollars worth of medications from Canada at far lower prices than in the United States, overriding fierce decades-long objections from the pharmaceutical industry. From a report: The approval, issued in a letter to Florida Friday, is a major policy shift for the United States, and supporters hope it will be a significant step forward in the long and largely unsuccessful effort to rein in drug prices. Individuals in the United States are allowed to buy directly from Canadian pharmacies, but states have long wanted to be able to purchase medicines in bulk for their Medicaid programs, government clinics and prisons from Canadian wholesalers.

Florida has estimated that it could save up to $150 million in its first year of the program, importing medicines that treat H.I.V., AIDS, diabetes, hepatitis C and psychiatric conditions. Other states have applied to the F.D.A. to set up similar programs. But significant hurdles remain. The pharmaceutical industry's major lobbying organization, the Pharmaceutical Research and Manufacturers of America, or PhRMA, which has sued over previous importation efforts, is expected to file suit to prevent the Florida plan from going into effect. Some drug manufacturers have agreements with Canadian wholesalers not to export their medicines, and the Canadian government has already taken steps to block the export of prescription drugs that are in short supply.

Little noticed, days before the holiday break, Boeing petitioned the Federal Aviation Administration for an exemption from key safety standards for the 737 MAX 7 -- the still-uncertified smallest member of its newest jet family. Seattle Times: Since August, earlier models of the MAX currently flying passengers in the U.S. have had to limit use of the jet's engine anti-ice system after Boeing discovered a defect in the system with potentially catastrophic consequences. The flaw could cause the inlet at the front end of the pod surrounding the engine -- known as a nacelle -- to break and fall off.

In an August Airworthiness Directive, the FAA stated that debris from such a breakup could penetrate the fuselage, putting passengers seated at windows behind the wings in danger, and could damage the wing or tail of the plane, "which could result in loss of control of the airplane." Dennis Tajer, a spokesperson for the Allied Pilots Association, the union representing 15,000 American Airlines pilots, said the flaw in the engine anti-ice system has "given us great concern." He said the pilot procedure the FAA approved as an interim solution -- urging pilots to make sure to turn off the system when icing conditions dissipate to avoid overheating that within five minutes could seriously damage the structure of the nacelle -- is inadequate given the serious potential danger.

"You get our attention when you say people might get killed," Tajer said. "We're not interested in seeing exemptions and accommodations that depend on human memory. ... There's just got to be a better way." In its petition to the FAA, Boeing argues the breakup of the engine nacelle is "extremely improbable" and that an exemption will not reduce safety. "The 737 MAX has been in service since 2017 and has accumulated over 6.5 million flight hours. In that time, there have been no reported cases of parts departing aircraft due to overheating of the engine nacelle inlet structure," the filing states.

China's top diplomat warned the US that decoupling would be "self defeating" as the country set out to implement a recent agreement made between their leaders. From a report: Foreign Minister Wang Yi, speaking on Friday at an event to mark the 45th anniversary of US-China diplomatic relations, cited a slew of initiatives that reflect improved ties including streamlined visas for US travelers, a counternarcotics working group to battle the flow of the synthetic fentanyl to the US, and the sending of pandas to the US by the end of the year. "Any decoupling attempt to stem the tide will only be counterproductive and self defeating," Wang said.

David Meale, deputy chief of mission at the U.S. Embassy in Beijing, joined Friday's event as charge d'affaires with Ambassador Nicholas Burns out of town. Tensions between China and the US started to ease after President Joe Biden and Chinese leader Xi Jinping met in November. The talks resulted in a resumption of high-level military-to-military ties, a promise to collaborate on the fentanyl problem and a commitment to boost interactions between people in the two countries.

An anonymous reader quotes a report from The Verge: Using satellite imagery and AI, researchers have mapped human activity at sea with more precision than ever before. The effort exposed a huge amount of industrial activity that previously flew under the radar, from suspicious fishing operations to an explosion of offshore energy development. The maps were published today in the journal Nature. The research led by Google-backed nonprofit Global Fishing Watch revealed that a whopping three-quarters of the world's industrial fishing vessels are not publicly tracked. Up to 30 percent of transport and energy vessels also escape public tracking. Those blind spots could hamper global conservation efforts, the researchers say. To better protect the world's oceans and fisheries, policymakers need a more accurate picture of where people are exploiting resources at sea.

Until now, Global Fishing Watch and other organizations relied primarily on the maritime Automatic Identification System (AIS) to see what was happening at sea. The system tracks vessels that carry a box that sends out radio signals, and the data has been used in the past to document overfishing and forced labor on vessels. Even so, there are major limitations with the system. Requirements to carry AIS vary by country and vessel type. And it's pretty easy for someone to turn the box off when they want to avoid detection, or cruise through locations where signal strength is spotty. To fill in the blanks, Kroodsma and his colleagues analyzed 2,000 terabytes of imagery from the European Space Agency's Sentinel-1 satellite constellation. Instead of taking traditional optical imagery, which is like snapping photos with a camera, Sentinel-1 uses advanced radar instruments to observe the surface of the Earth. Radar can penetrate clouds and "see" in the dark -- and it was able to spot offshore activity that AIS missed.

Since 2,000 terabytes is an enormous amount of data to crunch, the researchers developed three deep-learning models to classify each detected vessel, estimate their size, and sort out different kinds of offshore infrastructure. They monitored some 15 percent of the world's oceans where 75 percent of industrial activity takes place, paying attention to both vessel movements and the development of stationary offshore structures like oil rigs and wind turbines between 2017 and 2021. While fishing activity dipped at the onset of the covid-19 pandemic in 2020, they found dense vessel traffic in areas that "previously showed little to no vessel activity" in public tracking systems -- particularly around South and Southeast Asia, and the northern and western coasts of Africa.

A boom in offshore energy development was also visible in the data. Wind turbines outnumbered oil structures by the end of 2020. Turbines made up 48 percent of all ocean infrastructure by the following year, while oil structures accounted for 38 percent. Nearly all of the offshore wind development took place off the coasts of northern Europe and China. In the Northeast US, clean energy opponents have tried to falsely link whale deaths to upcoming offshore wind development even though evidence points to vessel strikes being the problem. Oil structures have a lot more vessels swarming around them than wind turbines. Tank vessels are used at times to transport oil to shore as an alternative to pipelines. The number of oil structures grew 16 percent over the five years studied. And offshore oil development was linked to five times as much vessel traffic globally as wind turbines in 2021. "The actual amount of vessel traffic globally from wind turbines is tiny, compared to the rest of traffic," Kroodsma says.

According to MoffettNathanson, the U.S. pay-TV industry had its worst-ever third quarter after losing about 900,000 subscribers. "That poor result, the research firm added, left the total pay-TV industry shrinking at a record pace of -7.3%, widened from a year-ago decline of -5.9%," reports Light Reading. "It also left pay-TV penetration of occupied households (including vMVPDs) at just 54.8% -- a level last seen in 1989, five years before the debut of DirecTV." From the report: Drilling down on Q3 results, traditional pay-TV providers (cable, telco and satellite) shed 1.97 million subscribers, widened from a loss of 1.94 million in the year-ago quarter. Within that category, US cable lost 1.10 million video subs in Q3, versus a loss of -1.09 million in the year-ago period. Satellite operators (Dish Network and DirecTV) lost 667,000 subs in Q3, versus -567,000 in the year-ago quarter. Telco TV providers lost 198,000 video subs in the period, an improvement when compared to a year-ago loss of -250,000 subs.

vMVPDs, meanwhile, added 1.08 million in Q3, down from a year-ago gain of about 1.34 million. Despite those gains, vMVPDs recaptured only 21.7% of traditional pay-TV's subscriber losses in the period, according to MoffettNathanson. Meanwhile, YouTube TV continues to dominate the vMVPD category. MoffettNathanson estimates that YouTube TV added about 350,000 subs in Q3, extending its total to 7 million -- representing 40% of the vMVPD sector's 18 million subscriber total. "Based on our Q3 estimate, YouTube TV has now surpassed Dish Network [6.72 million satellite TV subs at the end of Q3] to become the country's fourth largest MVPD of any kind," Moffett noted. "At the current trajectory, YouTube TV should pass DirecTV for third place in less than a year."

As spotted by X user bedros_p, Google appears to be preparing to introduce a paid upgrade for Bard Advanced, a "new, cutting-edge AI experience" announced in December that gives users access to Google's best models and capabilities. Android Police reports: According to the strings, you will be able to "Try Bard Advanced for 3 months, on us." After that test period, you will likely have to pay up for the service. A defunct link within the code suggests that it may be part of Google One, but it's not clear if Bard Advanced will be added to all tiers or only more expensive ones with more Google Drive storage. It's also possible that it will be an extra new tier in Google One.

As a refresher, Google launched its most capable AI model yet in December 2023, called Gemini. The LLM is available in three tiers, including a Nano version capable of running on devices like phones and a Pro version currently powering Bard in the US. There is also a Gemini Ultra which isn't public just yet, but supposedly outperforms other LLMs in almost all metrics. Google says that this is the one that will power Bard Advanced.

An anonymous reader quotes a report from the Los Angeles Times: The former Westside Pavilion, a long shuttered indoor mall, will be transformed into a UCLA biomedical research center aimed at tackling such towering challenges as curing cancer and preventing global pandemics, officials announced Wednesday. The sprawling three-story structure will be known as the UCLA Research Park and will house two multidisciplinary centers focusing on immunology and immunotherapy as well as quantum science and engineering. Establishment of the public-private research center is a coup for Southern California that "will cement California's global, economic, scientific and technical dominance into the 22nd century and beyond," said Gov. Gavin Newsom.

The former owners of the mall, Hudson Pacific Properties Inc. and Macerich, said Wednesday that they sold the property to the Regents of the University of California for $700 million. By purchasing the former shopping center, UCLA saved several years of potential toil to build such a facility on campus. UCLA is the most-applied-to university in the nation, but its Westwood home is among the smallest of the nine UC undergraduate campuses, leaving it limited room for growth. The former mall sits on prime real estate in the heart of the Westside at Pico Boulevard and Overland Avenue, about two miles from the UCLA campus. The mall was owned by commercial developers who spent hundreds of millions of dollars to dramatically remake the old shopping center into an office complex intended to appeal to technology firms, which signed some of the biggest office leases in L.A.'s Silicon Beach before the pandemic.

Google agreed to become the sole tenant and began paying rent last year yet never moved in. The interior is mostly unfinished, but is ready for UCLA to build out to its specifications in a process Newsom said would take about 40 months. The UCLA Research Park "will serve as a state of the art hub of research and innovation that will bring together academics, corporate partners, government agencies and startups to explore new areas of inquiry and achieve breakthroughs that serve the common good," UCLA Chancellor Gene Block said. In addition to flexible work areas, the former mall's 12-screen multiplex movie theater may be converted into lecture halls or performance spaces offering programming across the arts, humanities, sciences and social sciences, the chancellor's office said. One tenant of the research park will be the new California Institute for Immunology and Immunotherapy.

All new cars and vans bought in the UK must be zero emission by 2035, according to the latest legal mandate updated this week. From a report: The date for all new petrol and diesel cars to be banned was originally set for 2030. However, in September, Prime Minister Rishi Sunak pushed this date back to 2035. The government says this is giving consumers more time to make the switch and deal with the UK's charging infrastructure.

The transition will still be challenging. Eighty percent of new cars and 70 percent of new vans sold in Great Britain must be zero emission by 2030, increasing to 100 percent by 2035. While the government points to statistics indicating a 41 percent increase in zero-emission vehicles registered for the first time -- note, the vast majority of newly registered vehicles still remain conventionally powered -- charging infrastructure is an altogether different story. The government boasts of more than 50,000 public charge points, an increase of 44 percent year on year, but not all chargers are born equal. According to research from RAC, a local roadside assistance business, the government has failed to meet its target of having six or more rapid or ultra-rapid electric vehicle chargers at every motorway service area in England.

Germany's emissions hit a 70-year low last year as Europe's largest economy reduced its reliance on coal. From a report: A study by the thinktank Agora Energiewende found that Germany emitted 673m tonnes of greenhouse gases in 2023, 73m tonnes fewer than in 2022. The drop was "largely attributable to a strong decrease in coal power generation," Agora said, accounting for a reduction of 46m tonnes in CO2 emissions. Emissions from industry fell significantly, largely due to a decline in production by energy-intensive companies.

Electricity generation from renewable sources was more than 50% of the total in 2023 for the first time, while coal's share dropped to 26% from 34%, according to the federal network agency. Germany had resorted to coal following the Russian invasion of Ukraine, when Moscow cut off gas supplies. But since then Germany has significantly reduced its use of the fossil fuels.

A bestselling personal finance author and entrepreneur admits that he has more than $1 billion in debt -- and he doesn't think that's a bad thing. From a report: "If I go bust, the bank goes bust," said "Rich Dad, Poor Dad" author Robert Kiyosaki in a Nov. 30 Instagram reel. "Not my problem." That's because his debt has been used to purchase assets, he said in the video. He compared that with using debt to purchase liabilities, such as his Ferrari or Rolls-Royce vehicles -- expenses he's paid off in full, he said.

"I'm a billion dollars in debt because debt is money," Kiyosaki said during an interview on the "Disruptors" podcast. It connects to his strategy of using cash earnings to purchase precious metals like gold or silver, which Kiyosaki argues will retain their value while the U.S. dollar fluctuates: "toilet paper," he called it. Kiyosaki is one of the country's most well-known personal finance personalities. His 1997 book "Rich Dad, Poor Dad," which was originally self-published, has sold more than 40 million copies.

Alex Hern reports via the Guardian: The email newsletter service Substack is facing a user revolt after its chief executive defended hosting and handling payments for "Nazis" on its platform, citing anti-censorship reasons. In a note on the site published in December, the chief executive, Hamish McKenzie, said the firm "doesn't like Nazis," and wished "no one held these views." But he said the company did not think that censorship -- by demonetising sites that publish extreme views -- was a solution to the problem, and instead made it worse. Some of the largest newsletters on the service have threatened to take their business elsewhere if Substack does not reverse its stance.

On Tuesday Casey Newton, who writes Platformer -- a popular tech newsletter on the platform with thousands of subscribers paying at least $10 a month -- became the most prominent yet. [...] Substack takes a 10% cut of subscriptions from paid newsletters, meaning the loss of Platformer alone could represent six figures of revenue. Other newsletters have already made the jump. Talia Lavin, a journalist with thousands of paid subscribers on her newsletter The Sword and the Sandwich, moved to a competing service, Buttondown, on Tuesday. Substack's leadership team said in a statement: "As we face growing pressure to censor content published on Substack that to some seems dubious or objectionable, our answer remains the same: we make decisions based on principles not PR, we will defend free expression, and we will stick to our hands-off approach to content moderation."

Alexander Martin reports via The Record: The owner of an apartment in Veliky Novgorod in Russia has been arrested for discrediting the country's armed forces after a neighbor alerted the police to the message 'Slava Ukraini' scrolling across their LED curtains. When police went to the scene, they saw the garland which the owner had hung in celebration of the New Year and a "slogan glorifying the Armed Forces of Ukraine," as a spokesperson for the Ministry of Internal Affairs told state-owned news agency TASS. The apartment owner said the garland was supposed to display a "Happy New Year" greeting, TASS reported.

Several other people in Russia described a similar experience on the AlexGyver web forum, linked to a DIY blog popular in the country. They said at the stroke of midnight on New Year's Eve, their LED curtains also began to show the "Glory to Ukraine" message in Ukrainian. It is not clear whether any of these other posters were also arrested. The man in Veliky Novgorod will have to defend his case in court, according to TASS. Police have seized the curtain itself.

An independent investigation into the cause of the message by the AlexGyver forum users found that affected curtains all used the same open-source firmware code. The original code appears to have originated in Ukraine before someone created a fork translated into Russian. According to the Telegram channel for AlexGyver, the code had been added to the original project on October 18, and then in December the people or person running the fork copied and pasted that update into their own version. "Everyone who downloaded and updated the firmware in December received a gift," the Telegram channel wrote. The message was "really encrypted, hidden from the 'reader' of the code, and is displayed on the first day of the year exclusively for residents of Russia by [geographic region]."

Intuit is being questioned by US lawmakers who say federal tax credits the company received could have been better spent to build a free government alternative to Intuit's popular online tax preparation software, TurboTax. From a report: "For years, Intuit's corporate lobbyists have argued that the federal government should not set up a program for Americans to file their taxes online and for free because it would be too costly for taxpayers," the lawmakers, including Senators Elizabeth Warren and Bernie Sanders, wrote in a letter to the company. "Your company's disclosure reveals that Intuit's research tax break from 2022 alone could have been enough to fund a year of a free e-File program for millions of Americans."

The lawmakers asked Intuit to provide details on its research expenses dating to 2018. Warren, a Massachusetts Democrat, and Sanders, an Independent from Vermont, were joined on the letter by Senator Richard Blumenthal, a Connecticut Democrat, and Representative Katie Porter, a Democrat from California. The Internal Revenue Service, in a report to Congress last year, estimated it would cost $64 million to $249 million annually for the agency to run a free-filing program. In the fiscal year ending in July 2023, Mountain View, California-based Intuit received $106 million in federal research and experimentation credits, which amounted to about 4% of its total R&D expenses, according to a regulatory filing.

Montana and North Carolina have joined a growing list of states that now require identification to view porn, or are blocked from viewing it altogether, as new age verification laws went into effect on January 1. From a report: A year ago, Louisiana paved the way for a wave of age verification laws that target porn sites; eight states have since passed copycat age verification laws of their own. Montana's SB 544 and North Carolina's HB 8 are nearly identical to Louisiana's and other states' laws. The laws' text make unsubstantiated claims about the addictive potential of pornography and its apparent harms to viewers' health. North Carolina's law was passed as part of unrelated legislation that adds a computer science course to high school graduation requirements. Rather than try to make its users jump through hoops to view its content, Pornhub's parent company has blocked viewers in Montana and North Carolina altogether, as it has in other states with similar legislation.

A dinosaur fossil listed for sale in London for $20 million embodies one of the most heated debates in paleontology. From a report: When fossil hunters unearthed the remains of a dinosaur from the hills of eastern Montana five years ago, they carried several key characteristics of a Tyrannosaurus rex: a pair of giant legs for walking, a much smaller pair of arms for slashing prey, and a long tail stretching behind it. But unlike a full-grown T. rex, which would be about the size of a city bus, this dinosaur was more like the size of a pickup truck. The specimen, which is now listed for sale for $20 million at an art gallery in London, raises a question that has come to obsess paleontologists: Is it simply a young T. rex who died before reaching maturity, or does it represent a different but related species of dinosaur known as a Nanotyrannus?

The dispute has produced reams of scientific research and decades of debate, polarizing paleontologists along the way. Now, with dinosaur fossils increasingly fetching eye-popping prices at auction, the once-esoteric dispute has begun to ripple through auction houses and galleries, where some see the T. rex name as a valuable brand that can more easily command high prices. "It's ultimately a quite in-the-weeds question of the taxonomy and the classification of one very particular type of dinosaur," said Steve Brusatte, a paleontologist at the University of Edinburgh. "However, it involves T. rex, and the debate always gets a little bit more ferocious when the king of dinosaurs is involved."

On the internet, juvenile T. rex versus Nanotyrannus has become something of a meme, providing fuel for jokes on niche social media channels. ("I won't believe in Nanotyrannus until it shows up at my own door and devours me," a paleontology student with the handle "TheDinoBuff" joked recently on the social media site X.) The gallery selling the specimen discovered in Montana -- which is known as Chomper -- was faced with a choice. Call it a juvenile T. rex? Label it a Nanotyrannus? Or embrace the ambiguity of an unresolved scientific debate? The David Aaron gallery in London went with calling it a "rare juvenile Tyrannosaurus rex skeleton." It cited an influential 2020 paper on the subject led by Holly N. Woodward, which used an analysis of growth rings within bone samples from two disputed specimens -- which are estimated to have been similarly sized to Chomper -- to argue that they were juveniles nearing growth spurts.

According to new findings from the Millennium Cohort study, almost half of British teenagers say they feel addicted to social media. The Guardian reports: The latest research, by Dr Amy Orben's team at the University of Cambridge, used data from the Millennium Cohort study which is tracking the lives of about 19,000 people born in 2000-2002 across England, Scotland, Wales and Northern Ireland. When the cohort were aged 16-18 they were asked, for the first time, about social media use. Of the 7,000 people who responded, 48% said they agreed or strongly agreed with the statement "I think I am addicted to social media." A higher proportion of girls (57%) agreed compared to boys (37%), according to the data shared with the Guardian.

Scientists said this did not mean that these people are actually suffering from a clinical addiction, but that expressing a perceived lack of control suggests a problematic relationship. "We're not saying the people who say they feel addicted are addicted," said Georgia Turner, a graduate student leading the analysis. "Self-perceived social media addiction is not [necessarily] the same as drug addiction. But it's not a nice feeling to feel you don't have agency over your own behavior. It's quite striking that so many people feel like that and it can't it be that good."

"Social media research has largely assumed that [so-called] social media addiction is going to follow the same framework as drug addiction," said Turner. Orben's team and others argue that this is likely to be oversimplistic and are investigating whether the teenagers cluster into groups whose behavioral can be predicted by other personality traits. It could be that, for some, their relationship is akin to a behavioral addiction, but for others their use could be driven by compulsive checking, others may be relying on it to cope with negative life experiences, and others may simply be responding to negative social perceptions about "wasting time" on social media.

An anonymous reader quotes a report from Gizmodo: Facebook recently rolled out a new "Link History" setting that creates a special repository of all the links you click on in the Facebook mobile app. Users can opt-out, but Link History is turned on by default, and the data is used for targeted ads. The company pitches Link History as a useful tool for consumers "with your browsing activity saved in one place," rather than another way to keep tabs on your behavior. With the new setting you'll "never lose a link again," Facebook says in a pop-up encouraging users to consent to the new tracking method. The company goes on to mention that "When you allow link history, we may use your information to improve your ads across Meta technologies."

Facebook promises to delete the Link History it's created for you within 90 days if you turn the setting off. According to a Facebook help page, Link History isn't available everywhere. The company says it's rolling out globally "over time." This is a privacy improvement in some ways, but the setting raises more questions than it answers. Meta has always kept track of the links you click on, and this is the first time users have had any visibility or control over this corner of the company's internet spying apparatus. In other words, Meta is just asking users for permission for a category of tracking that it's been using for over a decade. Beyond that, there are a number of ways this setting might give users an illusion of privacy that Meta isn't offering. "The Link History doesn't mention anything about the invasive ways Facebook monitors what you're doing once you visit a webpage," notes Gizmodo's Thomas Germain. "It seems the setting only affects Meta's record of the fact that you clicked a link in the first place. Furthermore, Meta links everything you do on Facebook, Instagram, WhatsApp, and its other products. Unlike several of Facebook's other privacy settings, Link History doesn't say that it affects any of Meta's other apps, leaving you with the data harvesting status quo on other parts of Mark Zuckerberg's empire."

"Link History also creates a confusing new regime that establishes privacy settings that don't apply if you access Facebook outside of the Facebook app. If you log in to Facebook on a computer or a mobile browser instead, Link History doesn't protect you. In fact, you can't see the Link History page at all if you're looking at Facebook on your laptop."

The Crimson: Harvard President Claudine Gay will resign Tuesday afternoon, bringing an end to the shortest presidency in the University's history, according to a person with knowledge of the decision. It is not clear who will be appointed to serve as interim president.

University spokesperson Jonathan L. Swain declined to comment on Gay's decision to step down. Gay's resignation -- just six months and two days into the presidency -- comes amid growing allegations of plagiarism and lasting doubts over her ability to respond to antisemitism on campus after her disastrous congressional testimony Dec. 5.

Retired officers and departing defense officials are flocking to investment firms that are pushing the government to provide more money to defense-technology startups. The New York Times: When Defense Secretary Lloyd J. Austin III and other top officials assembled for an event this month at the Ronald Reagan Presidential Library, they walked into a lesson in how the high-stakes world of Pentagon lobbying is being altered by the rise of defense technology startups. Inside, at this elite gathering near Los Angeles of senior leaders from government and the arms industry, was a rapidly growing group of participants: former Pentagon officials and military officers who have joined venture capital firms and are trying to use their connections in Washington to cash in on the potential to sell a new generation of weapons.

They represent a new path through the revolving door that has always connected the Defense Department and the military contracting business. Retiring generals and departing top Pentagon officials once migrated regularly to the big established weapons makers like Lockheed Martin and Boeing. Now they are increasingly flocking to venture capital firms that have collectively pumped billions of dollars into Silicon Valley-style startups offering the Pentagon new war-fighting tools like autonomous killer drones, hypersonic jets and space surveillance equipment.

This new route to the private sector is one indicator of the ways in which the United States is trying to become more agile in harnessing technological advances to maintain military superiority over China and other rivals. But the close ties between venture capital firms and Defense Department decision makers have also put a new twist on long-running questions about industry access and influence at a time when the Pentagon is under pressure to rethink how it allocates its huge procurement budget.
