In recent years, private equity firms have been gobbling up physician practices to form powerful medical groups across the country, according to a new report. The New York Times: In more than a quarter of local markets -- in places like Tucson, Ariz.; Columbus, Ohio; and Providence, R.I. -- a single private equity firm owned more than 30 percent of practices in a given specialty in 2021. In 13 percent of the markets, the firms owned groups employing more than half the local specialists. The medical groups were associated with higher prices in their respective markets, particularly when they controlled a dominant share, according to a paper by researchers at the Petris Center at the University of California, Berkeley, and the Washington Center for Equitable Growth, a progressive think tank in Washington, D.C.

When a firm controlled more than 30 percent of the market, the cost of care in three specialties -- gastroenterology, dermatology, and obstetrics and gynecology -- increased by double digits. The paper, published by the American Antitrust Institute, documented substantial private equity purchases across multiple medical specialties over the last decade. Urology, ophthalmology, cardiology, oncology, radiology and orthopedics have also been major targets for such deals. "It's shocking when you look at it," said Laura Alexander, director of markets and competition policy for the Washington Center, who said private equity firms dominated only a handful of markets a decade ago. By looking at individual markets, the researchers were able to document the local impact. "National rates mask this much more acute problem in local markets," she said.

Long-time Slashdot reader hpickens writes: Richard A. Muller Has an interesting op-ed in the WSJ that asserts that World War III may not be what you expect (Source paywalled; alternative source) and that a two-front biological and cyberattack could lead to a U.S. defeat before we know what hit us. Muller paints a picture of what such a dual attack would look like. "The great value to the attacker of a two-pronged biological and cyber attack is the possibility of achieving destructive goals while keeping the whole operation covert," writes Muller. "Covid wasn't a deliberate attack, but it quickly and successfully damaged the American economy. Any nation thinking of using a deadly virus as a weapon of war would first need to immunize its own people, perhaps under the guise of a flu vaccination. Long-term population-level immunity would require the virus be sufficiently optimized, before release, to reduce the probability of further mutation."

The second prong of the attack would target hospitals with ransomware viruses. "Ransomware could simultaneously target energy grids, power plants, factories, refineries, trains, airlines, shipping, banking, water supplies, sewage-treatment plants and more. But hospitals would be the most salient targets. Avoiding obvious military targets would enhance the illusion that World War III hadn't begun."

"Deterring such an attack will require a clear, credible and articulated promise to respond to aggression. It can't be covert. If China, Russia or both attacked the U.S. this way, how would we react? Policy makers need to come up with an answer. An economic embargo seems suboptimal. Many would interpret nuclear retaliation as disproportionate. Developing a retaliatory virus would take time, and responding this way would clearly violate the Biological Weapons Convention."

An anonymous reader quotes a report from Ars Technica: Hundreds of Internet-exposed devices inside solar farms remain unpatched against a critical and actively exploited vulnerability that makes it easy for remote attackers to disrupt operations or gain a foothold inside the facilities. The devices, sold by Osaka, Japan-based Contec under the brand name SolarView, help people inside solar facilities monitor the amount of power they generate, store, and distribute. Contec says that roughly 30,000 power stations have introduced the devices, which come in various packages based on the size of the operation and the type of equipment it uses.

Searches on Shodan indicate that more than 600 of them are reachable on the open Internet. As problematic as that configuration is, researchers from security firm VulnCheck said Wednesday, more than two-thirds of them have yet to install an update that patches CVE-2022-29303, the tracking designation for a vulnerability with a severity rating of 9.8 out of 10. The flaw stems from the failure to neutralize potentially malicious elements included in user-supplied input, leading to remote attacks that execute malicious commands. Security firm Palo Alto Networks said last month the flaw was under active exploit by an operator of Mirai, an open source botnet consisting of routers and other so-called Internet of Things devices. The compromise of these devices could cause facilities that use them to lose visibility into their operations, which could result in serious consequences depending on where the vulnerable devices are used.

"The fact that a number of these systems are Internet facing and that the public exploits have been available long enough to get rolled into a Mirai-variant is not a good situation," VulnCheck researcher Jacob Baines wrote. "As always, organizations should be mindful of which systems appear in their public IP space and track public exploits for systems that they rely on." Baines said that the same devices vulnerable to CVE-2022-29303 were also vulnerable to CVE-2023-23333, a newer command-injection vulnerability that also has a severity rating of 9.8. Although there are no known reports of it being actively exploited, exploit code has been publicly available since February. Incorrect descriptions for both vulnerabilities are one factor involved in the patch failures, Baines said. Both vulnerabilities indicate that SolarView versions 8.00 and 8.10 are patched against CVE-2022-29303 and CVE-2023-293333. In fact, the researcher said, only 8.10 is patched against the threats.

Tessa Kaur, writing at The Gamer: This week, Disney removed a film called Crater from Disney Plus, which had been released on May 12, 2023. This means it was on the streaming platform for just 48 days, or about seven weeks. Disney hasn't said why, but it seems most likely that it didn't perform well enough and the company decided to remove it to write down the value of its "content assets," therefore lowering their taxes. It's all about the money, and always has been, and there are unfortunate consequences that come with this.

Disney isn't the only streamer that's guilty of this -- every streaming service, including Netflix and HBO Max (now just Max), has taken shows and movies off their platforms without warning. Willow was cancelled and removed from Disney, as was the well-loved Single Drunk Female from Hulu. HBO pulled Westworld and Snowpiercer. Grease: Rise of the Pink Ladies was cancelled and pulled from Paramount Plus just last month. It seems like anything could be pulled at any time, and that sucks.

It's bad enough that streaming services are cancelling shows left and right because they don't meet arbitrary sales targets, but when they are pulled from these platforms, many of them disappear forever. A lot of these shows are made for streaming, never aired on cable, and were never physically released. Bigger prestige shows like Westworld and Snowpiercer appeared on cable originally and are more likely to have Blu-ray releases, but those Disney shows are gone. There is no legal way to watch them anymore, and these companies are not interested in even selling you access.

Apple has been forced to make drastic cuts to production forecasts for the mixed-reality Vision Pro headset, unveiled last month after seven years in development and hailed as its most significant product launch since the iPhone. From a report: The complexity of the headset design and difficulties in production are behind the scaling back of targets, while plans for a more affordable version of the device have had to be pushed back, according to multiple people with direct knowledge of the manufacturing process.

Apple has already flagged that the $3,500 "spatial computing" headset device will not go on sale until "early next year," a lengthy gap from its June 5 launch. Analysts have interpreted this as being more to do with supply chain problems than allowing developers time to create apps for the Vision Pro. Two people close to Apple and Luxshare, the Chinese contract manufacturer that will initially assemble the device, said it was preparing to make fewer than 400,000 units in 2024. Multiple industry sources said Luxshare was currently Apple's only assembler of the device. Separately, two China-based sole suppliers of certain components for the Vision Pro said Apple was only asking them for enough for 130,000 to 150,000 units in the first year.

"People do not like eating insects. Livestock are less picky," writes the Economist. Of course, the insects need to eat, too. To date, they have mostly been reared on leftover chicken feed. But the supply of that is limited, and if insect-reared meat is to take off, new sources will be needed. In a paper in Applied Entomology, Niels Eriksen, a biochemist at Aalborg University, suggests feeding them on the waste products of the beer industry. The world knocks back around 185bn litres of beer every year. Each litre produces between three and ten litres of wastewater full of discarded barley and yeast . The mix is rich in protein but deficient in carbohydrates, especially compared with chicken feed.
The Economist reports that the researchers found brewery waste was "happily consumed" by insects they tested, which "grew equally well on either food source." This suggests the possibility that other plentiful and protein-rich food wastes could also become "reasonable targets for nutrient recycling by insects," including waste from other fermentation industries (like bioethanol), slaughterhouses, and sugar-beet waste.

VentureBeat is enjoying "secrets that spilled out" in the Microsoft/Activision Blizzard antitrust hearings. "Whether the Federal Trade Commission wins its antitrust case or not, its attempt to stop Microsoft's $68.7 billion acquisition of Activision Blizzard has revealed a trove of new data for everyone." The FTC has argued in a federal court that the merger would harm competition in the game industry and be bad for consumers, as Microsoft could pull Activision Blizzard's games like Call of Duty away from the Sony PlayStation, despite Microsoft's stated intention of not doing so for at least 10 years. In this case, the FTC might not have had an obvious winning hand, as the industry has an odd situation. Microsoft has the highest value ($104 billion in cash alone, versus $13.4 billion for Sony) at $2.49 trillion as a company compared to $115 billion for Sony, and yet it is in third place behind Sony and Nintendo.

Hence, there's some significance to Microsoft's Xbox first-party head, Matt Booty, sending an ill-advised email in 2019 saying Microsoft "has the ability to spend Sony out of business." That was long before the deal was announced 17 months ago, but it could be used as a sign of intent. Microsoft said it never pursued this strategy. While competing fiercely is fine, using monopoly power to drive a rival out of business so you can raise prices later is a no-no...

Did the FTC prove its case? I can't say just yet. Microsoft makes a decent point in saying all the regulators of the world except the U.S. and the United Kingdom have approved the deal. But I hope to have more reasons to binge on popcorn.
In January Ars Technica noted Microsoft's contract set July 18th as the deadline for closing the deal — or else paying a $3 billion "breakup fee". The Verge spotted that some of Sony's documents were poorly redacted. While looking at the lines that were crossed out with black pens, they could see that The Last of Us Part 2 cost the company $220 million to make, with 200 people working on it, while Horizon Forbidden West cost $212 million to make, with 300 working on it for over five years. Both games made considerably more money... In the unSharpied documents, Sony also revealed that a million Call of Duty players spent 100% of their time playing Call of Duty in 2021. It also said that Call of Duty generated $800 million for PlayStation in 2021 alone in the U.S. and perhaps $1.5 billion globally. It also looks like Sony's exclusive marketing deal with Activision for Call of Duty will expire in late 2023. Sony went on to say half of PS5 owners also have a Nintendo Switch.

Microsoft also failed to redact some of its acquisition targets. Those were later marked up, but not before Axios noted that the list included Thunderful, Supergiant Games, Niantic, Playrix, Zynga, Bungie, Square Enix, Warner Bros., Sega, IO Interactive and Scopely... Among the secrets revealed among the companies Microsoft acquired: Microsoft bought Ninja Theory, maker of Hellblade: Senua's Sacrifice, for $117 million.

China is shoring up its position as the world leader in renewable power and potentially outpacing its own ambitious energy targets, a report has found. The Guardian: China is set to double its capacity and produce 1,200 gigawatts of energy through wind and solar power by 2025, reaching its 2030 goal five years ahead of time, according to the report by Global Energy Monitor, a San Francisco-based NGO that tracks operating utility-scale wind and solar farms as well as future projects in the country.

It says that as of the first quarter of the year, China's utility-scale solar capacity has reached 228GW, more than that of the rest of the world combined. The installations are concentrated in the country's north and north-west provinces, such as Shanxi, Xinjiang and Hebei. In addition, the group identified solar farms under construction that could add another 379GW in prospective capacity, triple that of the US and nearly double that of Europe. China has also made huge strides in wind capacity: its combined onshore and offshore capacity now surpasses 310GW, double its 2017 level and roughly equivalent to the next top seven countries combined. With new projects in Inner Mongolia, Xinjiang, Gansu and along coastal areas, China is on course to add another 371GW before 2025, increasing the global wind fleet by nearly half.

The servers used by the GMP project, an open source arithmetic library at the heart of GCC and other programs, slowed to a crawl earlier this month due to a large amount of network traffic originating from Microsoft servers. The Register reports: Torbjorn Granlund, principal author of GMP, raised the alarm in a note to the project's mailing list. "The GMP servers are under attack by several hundred IP addresses owned by Microsoft Corporation," he wrote. "We do not know if this is made with malice by Microsoft, if it is some sort of mistake, or if [it is one] of their cloud customers ... running the attack. The attack targets the GMP repo, with thousands of identical requests. The requests are cleverly chosen as to cause heavy system load. "We're firewalling off all of Microsoft's IP addresses as an emergency response."

The following day, Mike Blacker, director of threat hunting, operations, and response at Microsoft's GitHub, had identified the culprit: a GitHub Actions Workflow that clones a Mercurial repo and has been forked more than 700 of times. "Microsoft and GitHub have investigated the issue and determined that a GitHub user updated a script within the FFmpeg-Builds project that pulled content from https://gmplib.org," explained Blacker. "This build was configured to run parallel simultaneous tests on 100 different types of computers/architectures. This activity does not appear to be nefarious. [GMP] appears to have limited infrastructure that could not sustain the limited, yet simultaneous requests." [...]

As of last week, the excessive traffic was still an issue. "Our servers are fully available again, but that's the result of us adding all participating Microsoft network ranges to our firewall," the GMP project explains on its webpage. "We understand that we are far from the first project to take such measures against Github." The Register asked Granlund whether he was satisfied with Microsoft-GitHub's response, and he told us he had only heard once from Blacker. "I blocked about 40 IP ranges from accessing our web server," he explained. "A week after this started, there was still intensive traffic from the same IP addresses, perhaps 100 different Microsoft addresses all in all, belonging to about 40 ranges. The difference was that that traffic just caused minuscule load, and a log line in the firewall." "Problem solved. I cannot care less if they no longer can access gmplib.org. I find it interesting how little responsibility Github/Microsoft assume here. They seem to think that they are entitled to bash away at smaller sites."

Investigations triggered by the cracking of encrypted phones three years ago have so far led to more than 6,500 arrests worldwide and the seizure of hundreds of tons of drugs, French, Dutch and European Union prosecutors said Tuesday. From a report: The announcement underscored the staggering scale of criminality -- mainly drugs and arms smuggling and money laundering -- that was uncovered as a result of police and prosecutors effectively listening in to criminals using encrypted EncroChat phones. "It helped to prevent violent attacks, attempted murders, corruption and large-scale drug transports, as well as obtain large-scale information on organised crime," European Union police and judicial cooperation agencies Europol and Eurojust said in a statement.

The French and Dutch investigation gained access to more than 115 million encrypted communications between some 60,000 criminals via servers in the northern French town of Roubaix, prosecutors said at a news conference in the nearby city of Lille. As a result, 6,558 suspects have been arrested worldwide, including 197 "high-value targets." Seized drugs included 30.5 million pills, 103.5 metric tons (114 tons) of cocaine, 163.4 metric tons (180 tons) of cannabis and 3.3 metric tons (3.6 tons) of heroin. The investigations also led to nearly 740 million euros ($809 million) in cash being recovered and assets or bank accounts worth another 154 million euros ($168 million) frozen.

Cyberattacks on US hospitals are on the rise, adding a layer of financial pressure onto an industry still struggling to recover from the pandemic. From a report: Health facilities have been hit with 226 digital incursions affecting 36 million people this year, on track to be more widespread than 2022 attacks, according to John Riggi, the national advisor for cybersecurity and risk at the American Hospital Association. Cyber raids on hospitals more than tripled in the past five years and have become more sophisticated, just when hospitals are coping with higher costs for labor and supplies and grappling with staff shortages. The industry in 2022 had what Moody's Investors Service analyst Matthew Cahill called "arguably the worst year in health-care history" for financial performance. "There's really no wiggle room for hospitals to deal with this," Cahill said in an interview. He said cyber risk has contributed to downgrades, including one at Missouri's Capital Region Medical Center last year following a breach.

Health-care facilities are attractive targets for cybercriminals because they hold ample personal data on patients, Matt Fabian and Lisa Washburn of Municipal Market Analytics wrote in a research note. Staffing shortages and wide use of third-party technology make the sector particularly vulnerable. The problem is particularly dire at smaller and rural hospitals, which have more financial distress and tend to use older technology. In an April note, Moody's cited an IBM survey that showed hospitals for 12 years have had the highest average cyberattack cost per industry, with $10.1 million in 2022. The AHA's Riggi said that while most hospitals have insurance, the cost to recover from attacks could be up to 10 times what insurance pays out.

An anonymous reader quotes a report from MIT Technology Review: If we're going to prevent the gravest dangers of global warming, experts agree, removing significant amounts of carbon dioxide from the atmosphere is essential. That's why, over the past few years, projects focused on growing seaweed to suck CO2 from the air and lock it in the sea have attracted attention -- and significant amounts of funding -- from the US government and private companies including Amazon. The problem: farming enough seaweed to meet climate-change goals may not be feasible after all.

A new study, published today in Nature Communications Earth & Environment, estimates that around a million square kilometers of ocean would need to be farmed in order to remove a billion tons of carbon dioxide from the atmosphere over the course of a year. It's not easy to come by that amount of space in places where seaweed grows easily, given all the competing uses along the coastlines, like shipping and fishing. To put that into context, between 2.5 and 13 billion tons of atmospheric carbon dioxide would need to be captured each year, in addition to dramatic reductions in greenhouse-gas emissions, to meet climate goals, according to the study's authors.

A variety of scientific models suggest we should be removing anything from 1.3 billion tons of carbon dioxide each year to 29 billion tons by 2050 in order to prevent global warming levels from rising past 1. 5C. An 2017 report from the UN estimated that we'd need to remove 10 billion tons annually to stop the planet from warming past 2C by the same date. "The industry is getting ahead of the science," says Isabella Arzeno-Soltero, a postdoctoral scholar at Stanford University, who worked on the project. "Our immediate goal was to see if, given optimal conditions, we can actually achieve the scales of carbon harvests that people are talking about. And the answer is no, not really." [...] Their findings suggest that cultivating enough seaweed to reach these targets is beyond the industry's current capacity, although meeting climate goals will require much more than reliance solely on seaweed.

Trial lawyer Kyle Roche has led an interesting life, according to the New York Times. He once earned $100 million selling bitcoin. He helped win a case against Craig Wright (who claims to be Bitcoin creator Satoshi Nakamoto) through his law firm Roche Freedman. And Roche also founded a startup that lets people bet on the outcome of (civil) lawsuits, "to make access to justice more affordable."

But something very bad for his career happened in January of 2022 when two businessmen flew Roche from Miami to the U.K. to discuss an investment. When he woke up the next morning, Roche said, he felt groggy... The brain fog was odd because he didn't think he'd had all that much to drink. As he flew back to Miami a few days later, Roche couldn't shake the feeling that something was amiss.

Months passed. Then, one day last summer, Roche's world detonated. A website called Crypto Leaks posted two dozen videos of him that had been secretly recorded during his meetings with Villavicencio and Ager-Hanssen. The videos portrayed Roche and his law firm, Roche Freedman, as being in the pocket of one of their crypto clients [Ava Labs]... In other clips, Roche made it sound like his sole concern, even when representing other clients, was to promote Ava Labs' interests...

One after another, companies that Roche Freedman had sued filed motions to disqualify the firm from their cases. In October, the first of those motions succeeded: A federal judge in New York tossed Roche Freedman from a case it had filed against Tether, the operator of the world's most used "stablecoin." Within days, Roche was forced to resign from the law firm he had founded. With his career in tatters, he said, he enrolled in ethics classes and began to see a therapist.
Roche calls the recorded remarks baseless bluster to impress a prospective investor (and alleges in court there are signs of deep fake alterations). While Roche "was felled by his own loose lips and his overly cozy relationship with a client," the Times reports "he also was the victim of an elaborate international setup." On April 3, 2020, Roche Freedman filed lawsuits seeking class-action status against seven issuers of digital coins, alleging they had pumped what amounted to unregistered securities with false statements and then dumped them, leaving retail investors holding the bag... Those suits were just an opening salvo: Sixteen months later, Roche filed his biggest securities fraud case yet. It alleged that a British entrepreneur, Dominic Williams, and entities he controlled had swindled investors out of billions of dollars by aggressively promoting, and then dumping, a digital coin tied to a grandiose plan to revolutionize computing. Williams had boldly proclaimed that his Internet Computer blockchain — a decentralized network of computers powered by a digital token called ICP — would supplant the big cloud services offered by Amazon and Microsoft and become humanity's primary computing platform. But after an initial surge that briefly made it one of the most valuable cryptocurrencies, ICP had plummeted 92% — a collapse that Roche's lawsuit attributed to "massive" selling by Williams and other insiders. (Williams denied the allegations.)
The Times reports that Roche's prospective investor Ager-Hanssen, "in addition to running his venture capital firm, has long had a sideline digging up dirt on behalf of wealthy clients entangled in business disputes in Britain and Scandinavia. On multiple occasions, he has secretly recorded his targets. For example, in a 2014 interview, he recounted how he had snared the adversary of a Swedish financier with a hidden microphone and boasted that he employed former intelligence officers from the CIA, MI6 and Mossad..." Roche believes them because he thinks he knows who hired Ager-Hanssen: Williams, the British entrepreneur who was the target of Roche Freedman's biggest pump-and-dump lawsuit... On May 12, 2022, Williams wrote on Twitter that he was "coming for" his critics. That was the same day the cryptoleaks.info domain name was registered. That was the same day the cryptoleaks.info domain name was registered. Then, on June 9, 2022, the Crypto Leaks website went live. Billing itself as the defender of "the honest crypto community," it posted two reports that aligned with Williams' interests...

The first espoused a complicated theory about the ICP token crash that Williams had previously floated on Twitter. The second attacked the Times for an article it had published about the crash. Williams tweeted a link to that Crypto Leaks report, calling it "Gobsmacking." The Dfinity Foundation, a Swiss nonprofit that Williams created to oversee his blockchain, has since sued the Times for defamation in New York. The Times is seeking to dismiss the suit. The videos of Roche were the crux of Crypto Leaks' third exposé. After they were published, Williams and Dfinity filed a motion to disqualify Roche Freedman as plaintiffs' counsel in the pump-and-dump lawsuit, saying Roche's comments demonstrated "a disregard for the integrity of the judicial system...."

Last month, the judge overseeing the pump-and-dump case granted Williams' motion and disqualified Freedman Normand Friedland as plaintiffs' counsel.

An anonymous reader quotes a report from TechCrunch: Wargraphs, a one-man-band startup behind a popular companion app for League of Legends called Porofessor, which helps players track and improve their playing stats, is getting acquired for up to [$54 million], half up front and half based on meeting certain earnings and growth targets. MOBA Networks, a company founded out of Sweden that buys, grows and runs online gaming communities (MOBA is short for "multiplayer online battle arena"), is buying the startup and its existing products. The plan is to expand them to more markets, in particular across Asia, and to build analytics for more titles.

I write "startup", but that might be with the loosest interpretation of the term. There is only a single employee, the mild-mannered Jean-Nicholas, and he has also entirely bootstrapped the business on his own. But that hasn't held him back. Wargraphs currently also builds analytics for Legends of Runeterra and Teamfight Tactics, but the League of Legends business has been its biggest it by far. Porofessor has had 10 million downloads of its app on Overwolf -- which is where Porofessor was built -- and more than 1.25 million daily active users if you combine traffic both from that platform and its own direct website. The company, such as it is, has been around for some 10 years, has pretty much always been profitable with revenues of 12.3 million euros in its last fiscal year. Jean-Nicholas told TechCrunch's Ingrid Lunden that he wants to build "a game" next. "Specifically, a card game that will compete against Hearthstone, coincidentally published by Activision Blizzard," writes Lunden. "He has no plans to raise outside funding for this, but he might hire an employee or two."

An anonymous reader quotes a report from SFGATE: A strange letter showed up on Kay Dean's doorstep. It was 2017, and the San Jose resident had left a one-star review on the Yelp page of a psychiatry office in Los Altos. Then the letter arrived: It seemed the clinic had hired a local lawyer to demand that Dean remove her negative review or face a lawsuit. The envelope included a $50 check. Dean, who once worked as a criminal investigator in the U.S. Department of Education's Office of Inspector General, smelled something fishy. She decided to look into the clinic, part of a small California chain called SavantCare. By the time her work was done, she'd found a higher calling -- and SavantCare's ex-CEO was fighting felony charges.

Since then, Dean, 60, has mounted a yearslong crusade against Yelp and the broader online review ecosystem from a home office in San Jose. Yelp, founded in San Francisco in 2004, is deeply entrenched in American consumer habits, and has burrowed itself into the larger consciousness through partnerships with the likes of Apple Maps. The company's crowdsourced reviews undergird the internet's web of recommendations and can send businesses droves of customers -- or act as an insurmountable black mark. Dean follows fake reviews from their origins in social media groups to when they hit the review sites, methodically documenting hours of research in spreadsheets and little-watched YouTube videos. Targets accuse her of an unreasonable fixation. Yelp claims it aggressively and effectively weeds out fakes. But Dean disagrees, and she's out to convince America that Yelp, Google and other purveyors of reviews cannot be trusted.

"This is an issue that affects millions of consumers, and thousands of honest businesses," she said in her YouTube page's introductory post on April 30, 2020, facing the camera dead-on. "I'm creating these videos to expose this massive fraud against the American public and shine a light on Big Tech's culpability." "I don't do it lightly. If I put a video up, it's serious," she told SFGATE in May. "I'm putting myself out there." Dean is particularly motivated by the types of small businesses that she's found gaming Yelp's recommendation algorithm. She has spotted seemingly paid-for reviews on the pages of lawyers, home contractors, and doctors' offices -- high-ticket companies for which she says she'd "rather have no information than fake information."

Researchers at the California Institute of Technology (Caltech) have successfully demonstrated the capability of steering power in a microwave beam from a satellite to targets in space, as well as transmitting some of that power to a detector on Earth. Science Magazine reports: The Caltech mission, funded by the Donald Bren Foundation and Northrop Grumman Corporation, aimed to go a step further with lightweight, inexpensive, and flexible components. The microwave transmitter was an array of 32 flat antennas packed onto a surface slightly larger than a dinner plate. By varying the timing of signals sent to the different antennas, the researchers could steer the array's beam. They pointed it at a pair of microwave receivers about a forearm's distance away and switched the beam from one receiver to the other at will, lighting up an LED on each.

The transmitted power was small, just 200 milliwatts, less than that of a cellphone camera light. But the team was still able to steer the beam toward Earth and detect it with a receiver at Caltech. "It was a proof of concept," says Caltech electrical engineer Ali Hajimiri. "It indicates what an overall system can do."

The Caltech spacecraft still has two more planned experiments. One is now testing 32 different varieties of solar cell to see which best survives the rigors of space. The second is a folded piece of ultralight composite material that will unfurl into a sail-like structure 2 meters across. Although the sail will not hold any solar cells, it is meant to test the kind of thin, flexible, and large deployments required for a future power station.

The Washington Post looks at a new study co-authored by Nels Johnson, senior practice adviser for renewable energy development at the Nature Conservancy nonprofit.

Its underlying point: the current way of building renewables will not work. "If we take the business-as-usual approach, land conflicts will probably prevent us from getting to these ambitious clean energy targets," said Jason Albritton, director of the Nature Conservancy's North American climate mitigation program and one of Johnson's co-authors... In its report, the Nature Conservancy describes two different futures in which the United States achieves net-zero carbon emissions by 2050. In one future — call it "business as usual" — wind and solar farms are built haphazardly, with little consideration for land impacts. In the other future, developers use land more efficiently. Business as usual would require 266,410 square miles — an area around the size of Texas — to fit all the solar panels and wind turbines, plus batteries to store electricity when sunlight and wind are unavailable and long-distance transmission lines to bring power from rural areas to towns and cities.

The researchers used a statistical model to discover the suite of technologies that would minimize land impacts. A smarter strategy, they found, could slash that footprint by more than half, to 114,642 square miles — a little bigger than Arizona. That's still a lot of land, but it would reduce the opportunities for conflict, the researchers said. The model recommends building more solar and less wind, since photovoltaics produce more power with less land than turbines do... The study sees rooftop solar generating far less power than large solar farms. If one in three rooftops have solar panels by 2050 — a high-end assumption — rooftop solar would contribute 15 percent of U.S. solar power, according to the researchers. "It's an important part of the picture, but it will not ever be totally sufficient," Johnson said.

The researchers also found land savings by avoiding productive farmland and instead building on abandoned fields or rehabilitated mines, landfills and hazardous waste sites known as brownfields.

Venture capital funds, private equity groups and accountancy firms are using the latest artificial intelligence to pick acquisition targets and start-ups for investment, betting the technology can give them an edge over rivals. From a report: Big Four accountant KPMG, hedge fund Coatue and venture capital firm Headline are among those using the latest AI tools to advise clients and help guide their dealmaking. With investors under pressure to identify the next high-growth start-up at a time when few companies are going public, some argue that dealmakers can benefit from using generative AI for tasks such as assessing a company's growth potential based on financial analysis.

"If you can train or use a model that gets a lot of efficiency first, you will get an advantage in that particular area of the business that is harder for a second mover to do," said Par Edin, who leads innovation in KPMG's US deal advisory and strategy business. "It is about getting there first for each and every particular use case." The pace of artificial intelligence development over the past six months, triggered by the release of OpenAI's popular ChatGPT -- a chatbot that provides humanlike answers to queries -- has spurred investors to use the tools to identify fast-growing companies and acquisition targets.

The two Koreas are elevating a space race aimed at modernizing how each country monitors the other's improving military firepower. From a report: As hopes for a diplomatic breakthrough have dimmed in recent years, North and South Korea have grown more antagonistic toward one another and upped their displays of military might. They have traded missile tests. Pyongyang has sent drones that flew over downtown Seoul. South Korea has sharpened security and defense ties with the U.S. and Japan. The rise in tensions has elevated the importance -- and need -- for spy-satellite technology that neither country now has. South Korea cleared a significant technological marker on Thursday, launching multiple commercial satellites aboard a homegrown rocket for the first time. North Korea's Kim Jong Un regime stands poised to soon fly its first military reconnaissance satellite.

Nuri, South Korea's three-stage liquid-fuel rocket, blasted off at 6:24 p.m. local time Thursday from the Naro Space Center in Goheung, a city on the country's southern coast. The 200-ton rocket launched into space and deployed eight satellites into orbit about 342 miles above Earth, about 13 minutes after liftoff. Seoul has the clear technological advantage, weapons analysts say, though Pyongyang has been quick to advance its sanctioned missile program to develop long-range rockets that can carry satellites. Both nations remain years away from having a full-fledged network of spy satellites. But attaining the technology would allow the countries to identify military targets to precisely launch strikes during potential conflict without relying on their allies' satellite technology for information. In North Korea's case, space-based satellite technology is essential for its nuclear strategy. Having eyes in the sky would serve as an additional asset to launching nuclear strikes with better accuracy, said Yang Uk, a military expert at the Asan Institute for Policy Studies, a think tank in Seoul. Should the technology progress enough, North Korea could potentially identify nuclear strike targets in the U.S., he added.

Microsoft has issued a warning that Chinese state-sponsored hackers, known as "Volt Typhoon," have compromised "critical" U.S. cyber infrastructure across various industries with a focus on gathering intelligence. CNBC reports: The Chinese hacking group, codenamed "Volt Typhoon," has operated since mid-2021, Microsoft said in an advisory. The organization is apparently working to disrupt "critical communications infrastructure between the United States and Asia," Microsoft said, to stymie efforts during "future crises." The National Security Agency put out a bulletin (PDF) on Wednesday, detailing how the hack works and how cybersecurity teams should respond.

The attack is apparently ongoing. In an advisory, Microsoft urged impacted customers to "close or change credentials for all compromised accounts." U.S. intelligence agencies became aware of the incursion in February, around the same time that a Chinese spy balloon was downed, the New York Times reported. The infiltration was focused on communications infrastructure in Guam and other parts of the U.S., the Times reported, and was particularly alarming to U.S. intelligence because Guam sits at the heart of an American military response in case of a Taiwanese invasion.

Volt Typhoon is able to infiltrate organizations using a unnamed vulnerability in a popular cybersecurity suite called FortiGuard, Microsoft said. Once the hacking group has gained access to a corporate system, it steals user credentials from the security suite and uses them to try to gain access to other corporate systems. The state-sponsored hackers aren't looking to create disruption yet, Microsoft said. Rather, "the threat actor intends to perform espionage and maintain access without being detected for as long as possible." Infrastructure in nearly every critical sector has been impacted, Microsoft said, including the communications, transport, and maritime industries. Government organizations were also targeted.
