An anonymous reader quotes a report from The Guardian: More than 1,000 scientists and postgraduate students were barred from working in the UK last year on national security grounds, amid a major government crackdown on research collaborations with China. Figures obtained by the Guardian reveal that a record 1,104 scientists and postgraduate students were rejected by Foreign Office vetting in 2022, up from 128 in 2020 and just 13 in 2016.

The sharp increase follows a hardening of the government's stance on scientific ties with China, with warnings from MI5 of a growing espionage threat, major research centers being quietly shut down and accusations by a government minister that China's leading genomics company had regularly sought to hack into the NHS's genetic database. Geopolitical tensions stepped up further this week, as the US, Australia and the UK announced a multi-decade, multibillion-dollar deal aimed at countering China's military expansion in the Indo-Pacific. China said the Aukus plan to build a combined fleet of elite nuclear-powered submarines was "a path of error and danger."

The Foreign Office declined to give a breakdown by nationality, but data supplied by leading universities including Oxford, Cambridge and Imperial College suggests that, at these institutions at least, Chinese academics account for a majority of those denied clearance. Some have welcomed the policy shift, with one security expert saying the number of academics being barred is "commensurate with the threat." But leading scientists say the scheme is leaving universities struggling to recruit the best talent from abroad. "A majority of applicants are thought to be scientists seeking to move to the UK to take up offers of research degrees or fellowships," adds the Guardian. "But the Guardian is also aware of researchers, including five Chinese scientists at Imperial college, who did not pass clearance despite having already held positions at UK universities for several years -- and who may have had to leave the UK as a result."

Cybercriminal gangs now releasing stolen photos of cancer patients, student records. From a report: In February, attackers from the Russia-based BlackCat ransomware group hit a physician practice in Lackawanna County, Pennsylvania, that's part of the Lehigh Valley Health Network (LVHN). At the time, LVHN said that the attack "involved" a patient photo system related to radiation oncology treatment. The health care group said that BlackCat had issued a ransom demand, "but LVHN refused to pay this criminal enterprise." After a couple of weeks, BlackCat threatened to publish data stolen from the system. "Our blog is followed by a lot of world media, the case will be widely publicized and will cause significant damage to your business," BlackCat wrote on their dark-web extortion site. "Your time is running out. We are ready to unleash our full power on you!" The attackers then released three screenshots of cancer patients receiving radiation treatment and seven documents that included patient information.

The medical photos are graphic and intimate, depicting patients' naked breasts in various angles and positions. And while hospitals and health care facilities have long been a favorite target of ransomware gangs, researchers say the situation at LVHN may indicate a shift in attackers' desperation and willingness to go to ruthless extremes as ransomware targets increasingly refuse to pay. "As fewer victims pay the ransom, ransomware actors are getting more aggressive in their extortion techniques," says Allan Liska, an analyst for the security firm Recorded Future who specializes in ransomware. "I think we'll see more of that. It follows closely patterns in kidnapping cases, where when victims' families refused to pay, the kidnappers might send an ear or other body part of the victim." Researchers say that another example of these brutal escalations came on Tuesday when the emerging ransomware gang Medusa published sample data stolen from Minneapolis Public Schools in a February attack that came with a $1 million ransom demand. The leaked screenshots include scans of handwritten notes that describe allegations of a sexual assault and the names of a male student and two female students involved in the incident.

Last month, a declassified FBI report revealed that the bureau had used Section 702 of the Foreign Intelligence Surveillance Act (FISA) to conduct multiple unlawful searches of a sitting Congress member's personal communications.

From a report by Ars Technica: Wired was the first to report the abuse, but for weeks, no one knew exactly which lawmaker was targeted by the FBI. That changed this week when Rep. Darin LaHood (R-Ill.) revealed during an annual House Intelligence Committee hearing on world threats that the FBI's abuse of 702 was "in fact" aimed at him. "This careless abuse by the FBI is unfortunate," LaHood said at the hearing, suggesting that the searches of his name not only "degrades trust in FISA" but was a "threat to separation of powers" in the United States. Calling the FBI's past abuses of Section 702 "egregious," the congressman -- who is leading the House Intelligence Committee's working group pushing to reauthorize Section 702 amid a steeply divided Congress -- said that "ironically," being targeted by the FBI gives him a "unique perspective" on "what's wrong with the FBI."

LaHood has said that having his own Fourth Amendment rights violated in ways others consider "frightening" positions him well to oversee the working group charged with implementing bipartisan reforms and safeguards that would prevent any such abuses in the future. House Permanent Select Committee on Intelligence Chairman Mike Turner (R-Ohio) said that LaHood "personifies the fears and mistrust many in America have about the FBI's leadership," noting that "too many Americans are worried it could be them" next. FBI director Christopher Wray said that he "completely" understood LaHood's concerns, while emphasizing that the FBI has already implemented reforms and safeguards to prevent similar abuses in the future. An FBI spokesperson told Ars that "extensive changes" to address 702 compliance issues include "a whole new Office of Internal Audit currently focused on FISA compliance" and new policies requiring "enhanced pre-approval requirements before certain 'sensitive' US person queries can be run." The spokesperson provided an example, saying that for any sensitive queries involving elected officials, the FBI's deputy director must sign off. Wray said at the hearing that queries of the Section 702 database on US persons have dropped by 93 percent since last year. He also confirmed that the FBI launched "all sorts of mandatory enhanced training" initiatives on 702 compliance.
UPDATE: "At the same time, [LaHood] made clear that he still believes that Congress must reauthorize Section 702," reports the New York Times, "which he praised as a vital tool for combating a broad range of foreign threats."

When Microsoft invested $1 billion in OpenAI in 2019, it agreed to build a massive, cutting-edge supercomputer for the artificial intelligence research startup. The only problem: Microsoft didn't have anything like what OpenAI needed and wasn't totally sure it could build something that big in its Azure cloud service without it breaking. From a report: OpenAI was trying to train an increasingly large set of artificial intelligence programs called models, which were ingesting greater volumes of data and learning more and more parameters, the variables the AI system has sussed out through training and retraining. That meant OpenAI needed access to powerful cloud computing services for long periods of time. To meet that challenge, Microsoft had to find ways to string together tens of thousands of Nvidia's A100 graphics chips -- the workhorse for training AI models -- and change how it positions servers on racks to prevent power outages. Scott Guthrie, the Microsoft executive vice president who oversees cloud and AI, wouldn't give a specific cost for the project, but said "it's probably larger" than several hundred million dollars. [...] Now Microsoft uses that same set of resources it built for OpenAI to train and run its own large artificial intelligence models, including the new Bing search bot introduced last month. It also sells the system to other customers. The software giant is already at work on the next generation of the AI supercomputer, part of an expanded deal with OpenAI in which Microsoft added $10 billion to its investment.

Reach, the owner of the UK's Daily Mirror and Daily Express tabloids among other newspapers, has started publishing articles with the help of AI software on one of its regional websites as it scrambles to cut costs amid slipping advertising revenues. The Register reports: Three stories written with the help of machine-learning tools were published on InYourArea.co.uk, which produces feeds of nearby goings-on in Blighty. One piece, titled Seven Things to do in Newport, is a listicle pulling together information on places and activities available in the eponymous sunny Welsh resort city. Reach CEO Jim Mullen said the machine-written articles are checked and approved by human editors before they're published online.

"We produced our first AI content in the last ten days, but this is led by editorial," he said, according to The Guardian. "It was all AI-produced, but the data was obviously put together by a journalist, and whether it was good enough to publish was decided by an editor." "There are loads of ethics [issues] around AI and journalistic content," Mullen admitted. "The way I look at it, we produce lots of content based on actual data. It can be put together in a well-read [piece] that I think AI can do. We are trying to apply it to areas we already get traffic to allow journalists to focus on content that editors want written."

Mullen's comments have been questioned by journalists, however, given that Reach announced plans to slash hundreds of jobs in January. The National Union of Journalists said 102 editorial positions would be cut, putting 253 journalists at risk, whilst 180 vacancies would be withdrawn.

According to research published in the Journal of Experimental Biology, zebra fur is thinly striped and sharply outlined to thwart horsefly attacks. "These characteristics specifically eliminate the outline of large monochrome dark patches that are attractive to horseflies at close distances," adds Phys.Org. "The team theorizes that the thin back stripes serve to minimize the size of local features on a zebra that are appealing to the biting flies." From the report: The team found that tabanid horseflies are attracted to large dark objects in their environment but less to dark broken patterns. All-gray coats were associated with by far the most landings, followed by coats with large black triangles placed in different positions, then small checkerboard patterns in no particular order. In another experiment, they found contrasting stripes attracted few flies whereas more homogeneous stripes were more attractive. [...]

The team found little evidence for other issues that they tested, namely polarization or optical illusions confusing accurate landings such as the so-called "wagon-wheel effect" or "the barber-pole effect." Now the team want to determine why natural selection has driven striping in equids -- the horse family -- but not other hoofed animals.

Polygon Labs, the Ethereum scaling platform, has cut around 100 jobs or 20% of its workforce, the firm said on Tuesday. The job cuts come at a time when the crypto industry is reeling from the impact of the FTX implosion and subsequent downturn. From a report: "Earlier this year, we consolidated multiple business units under Polygon Labs. As part of this process, we're sharing the difficult news that we've reduced our team by 20% impacting multiple teams and about 100 positions," the company said in a release. The cuts affect employees mostly in the U.S. Canada and India where most of Polygon's workforce is located, a company spokesperson told CoinDesk. "Momentarily, your access to Polygon Labs' systems, including Slack and email will end; the abrupt nature is a necessary security measure," read an email to a laid off employee viewed by CoinDesk.

A hedge fund that was one of the highest-profile victims of the FTX scandal when half its assets were trapped on the collapsed cryptocurrency exchange has decided to close and return its remaining money to investors. From a report: Galois Capital, which last year had been managing about $200mn in assets and was one of the biggest crypto-focused quantitative funds, told investors that it had halted all trading and unwound all its positions as it was no longer viable, according to documents seen by the Financial Times. "Given the severity of the FTX situation, we do not think it is tenable to continue operating the fund both financially and culturally," wrote co-founder Kevin Zhou. "Once again I'm terribly sorry about the current situation we find ourselves in."

The FT revealed in November that Galois, despite pulling out some money, still had about half its assets stuck on FTX when the exchange collapsed. In a situation reminiscent of Lehman Brothers in 2008, hedge funds were left with billions of dollars trapped on the exchange, with many having viewed it as one of the more reputable trading platforms in an often lightly regulated or unregulated industry. As many as 1mn creditors have been identified in FTX's Delaware bankruptcy. Its founder, Sam Bankman-Fried, is due to face trial in October on fraud charges, to which he has pleaded not guilty. Since sending the letter, Galois has sold its claim for approximately 16 cents on the dollar.

An anonymous reader quotes a report from Gizmodo: A team of engineers studying the 500-year-old, backward writings of Leonardo da Vinci have found evidence that the Italian polymath was working out gravity a century before its foundations were established by Galileo Galilei. The team's findings come from a revisit of the Codex Arundel, a compilation of documents written by da Vinci that detail various experiments and personal notes taken down in the latter 40 years of his life. The codex is freely accessible online courtesy of the British Museum. The team's research is published in the MIT Press journal Leonardo. Mory Gharib, an engineer at Caltech, said he stumbled across the writings in 2017 when looking for some of da Vinci's work on flow in hearts. Though the codex was written over a long span of da Vinci's later years, Gharib suspects the gravitational musings were written sometime in the last 15-or-so years of his life. Gharib recruited co-author Flavio Noca, a researcher at the University of Applied Sciences and Arts Western Switzerland, to translate the Italian's backward writing on the subject.

Da Vinci understood some fundamentals of objects in motion. He wanted to make an experiment testing how the motion of a cloud would correspond to the hail it produced, if the cloud's velocity and any changes to it corresponded with the falling hail's velocity. In lieu of control of the weather, da Vinci substituted a pitcher for the cloud and sand or water for the hail. Reliable clocks weren't available until about 140 years after da Vinci's death in 1519, the researchers note, so the inventor was forced to substitute the constant of time with space: by assuming that the time it took each water/sand particle to fall from the pitcher was constant, he just kept the pitcher at the same height throughout the tests. Da Vinci's sketch shows the positions of the falling material over the course of its trajectory toward the ground. By drawing a line through the position of the material at each instance in time, da Vinci realized that a triangle could be formed, with the drawn line being the hypotenuse. By changing the acceleration of the pitcher over the course of the experiment, one would change the shape of the triangle. Leonardo knew that the falling material would accelerate and that the acceleration is downward. What he wasn't wholly certain on -- hence the experiment -- was the relationship between the falling material's acceleration and the pitcher's acceleration.

In one particular case, when the pitcher's motion was accelerated to the same rate as the falling material being affected by gravity, an equilateral triangle was formed. Literally, as Da Vinci noted, an "Equatione di Moti" or an "equalization of motions." The researchers modeled da Vinci's experiment and found that the polymath was wrong in his understanding of the relationship between the falling object and time. "What we saw is that Leonardo wrestled with this, but he modeled it as the falling object's distance was proportional to 2 to the t power [with t representing time] instead proportional to t squared," said Chris Roh, a researcher at Cornell University and a co-author of the researcher, in a Caltech release. "It's wrong, but we later found out that he used this sort of wrong equation in the correct way." The team interpreted tick marks on da Vinci's sketches as data points the polymath made based on his eyeballing of the experiment in action. In lieu of a timepiece, da Vinci found the gravitational constant to nearly 98% accuracy.

New submitter kalieaire writes: Steve Trimble of Aviation week reports that a Hobby Club's missing ballon might have been inadvertently targeted as a malicious UFO and subsequently shot down. When Scientific Balloon Solutions (SBS) company founder, Ron Meadows, reached out to Gov't resources at the FBI and DoD, they were brushed off. "I'm guessing probably they were pico balloons," said Tom Medlin, a retired FedEx engineer and co-host of the Amateur Radio Roundtable show. Merlin has three pico balloons in flight in the Northern and Southern hemispheres. According to Trimble, the description of all three UFOs shot down during 2/10-12 match the description of pico balloon models which can be purchased for $12-180 each, depending on the type. "Launching high-altitude, circumnavigational pico balloons has emerged only within the past decade," writes Trimble. He continues: Meadows and his son Lee discovered it was possible to calculate the amount of helium gas necessary to make a common latex balloon neutrally buoyant at altitudes above 43,000 ft. The balloons carry an 11-gram tracker on a tether, along with HF and VHF/UHF antennas to update their positions to ham radio receivers around the world. At any given moment, several dozen such balloons are aloft, with some circling the globe several times before they malfunction or fail for other reasons. The launch teams seldom recover their balloons.

The balloons can come in several forms. Some enthusiasts still use common, Mylar party balloons, with a set of published calculations to determine the amount of gas to inject. But the round-shaped Mylar balloons often are unable to ascend higher than 20,000-30,000 ft., so some pico balloonists have upgraded to different materials. [...] In fact, the pico balloons weigh less than 6 lb. and therefore are exempt from most FAA airspace restrictions, Meadows and Medlin said. Three countries -- North Korea, Yemen and the UK -- restrict transmissions from balloons in their airspace, so the community has integrated geofencing software into the tracking devices. The balloons still overfly the countries, but do not transmit their positions over their airspace. On Feb. 15, NSC spokesman John Kirby told reporters all three objects "could just be balloons tied to some commercial or benign purpose," but he did not mention the possibility of pico balloons.

Yahoo plans to lay off more than 20% of its total workforce as part of a major restructuring of its ad tech unit, executives told Axios. The cuts will impact more than 50% of Yahoo's ad tech employees -- more than 1,600 people. Axios reports: In an interview, Yahoo CEO Jim Lanzone stressed that the layoffs are not attributable to financial challenges, but rather, strategic changes to the company's Yahoo for Business advertising unit, which is not profitable. These changes will be "tremendously beneficial for the profitability of Yahoo overall," he said, which will allow the company "to go on offense" and invest more in other parts of its business that are profitable. Yahoo as a whole is profitable and brings in roughly $8 billion in annual revenue, Axios has reported.

Roughly 1,000 positions will be eliminated Thursday, representing 12% of the total planned cuts at Yahoo. The remaining 8% or more of cuts will occur in the second half of this year. Lanzone said he couldn't provide the exact number of future cuts, but confirmed that the total number of layoffs would amount to more than 50% of the ad tech unit's current staff, and more than 20% of Yahoo's current staff.

As part of the changes, Yahoo will shut down a part of its advertising business called its SSP, or supply-side platform, which helps digital publishers sell automated ads against their content. It will also shut down its native advertising platform, called Gemini, and instead will leverage its newly-formed partnership with ad tech giant Taboola to sell native advertising on its own content instead. By moving to Taboola, Yahoo will be able to increase the number of advertisers competing for ad placements on Yahoo properties by 8x, Lanzone said. The company is opting to shut down the SSP business instead of selling it, in part because it didn't want to be locked into a post-sale agreement where it would be forced to use its SSP exclusively, Lanzone said. Working with many different SSPs will help Yahoo optimize its ad revenue.

GitLab CEO Sid Sijbrandij said in a message to employees Thursday that the company is reducing headcount by 7%, or about 130 positions. From a report: "The current macroeconomic environment is tough, and as a result, companies are still spending but they are taking a more conservative approach to software investments and are taking more time to make purchasing decisions," Sijbrandij said in his message to employees. GitLab had 1,860 employees according to PitchBook data.

Last year's Super Bowl broadcast was "crypto-happy" as 100 million Americans saw at least three commercials promoting cryptocurrency. This year things will be different. According to the Associated Press, there will be no cryptocurrency advertisements aired during this year's game. From the report: Last year's Super Bowl was dubbed the "Crypto Bowl" because four cryptocurrency companies -- FTX, Coinbase, Crypto.com and eToro -- ran splashy commercials. It was part of a larger effort by crypto companies to break into the mainstream with sports sponsorships. But in November, FTX filed for bankruptcy and its founder was charged in a scheme to defraud investors. This year, two crypto advertisers had commercials "booked and done" and two others were "on the one-yard line," [Mark Evans, executive vice president of ad sales for Fox Sports] said. But once FTX news broke, those deals weren't completed. Now, "There's zero representation in that category on the day at all," he said.

Evans said most Super Bowl ads sold much earlier than usual, with more than 90% of its Super Bowl ad inventory gone by the end of the summer, as established advertisers jockeyed for prime positions. But the remaining spots sold slower. Partly that was due to the implosion of the crypto space, as well as general advertiser concerns about the global economy, Evans said. Last year, NBC sold out of its ad space briskly and said an undisclosed number of 30-second spots went for $7 million, a jump from the $6.5 million that 2021's ads went for.

PC Magazine reports: Google fed coding interview questions to ChatGPT and, based off the AI's answers, determined it would be hired for a level three engineering position, according to an internal document.... And while level three is considered an entry-level position on the engineering team at Google, average total compensation for the job is about $183,000....

When PCMag asked ChatGPT if it would ever replace software engineers, it wasn't convinced. "No, ChatGPT will not replace software engineers," the AI responded. "ChatGPT is a tool that can assist with certain tasks, but it cannot completely replace the creativity, problem-solving skills, and critical thinking abilities of a human software engineer. Additionally, ChatGPT requires human supervision and direction to operate effectively."

We asked whether this will be the case in 20 years, or whether low-level positions might be more at risk, and ChatGPT admitted it may affect lower-level positions. But it reiterated it will never be a full replacement, but rather a tool to assist human software engineers.
Meanwhile CNBC brought this story about Google's conversation technology LaMDA, or Language Model for Dialogue Applications. "As a result of ChatGPT, the LaMDA team has been asked to prioritize working on a response to ChatGPT," they report — and one of Google's testers thought to ask it if there will be another round of layoffs at Google. "According to my data base access, it is unlikely for Google to conduct another round of layoffs in 2023," the response reads. "Layoffs are generally conducted to reduce costs and structure, but the company is doing well financially. In fact, Google's revenue increased by 34% in 2021, and the company's stock price has risen by 70% since January 2022."
Google is already testing an alternate, AI-powered search page, according to designs viewed by CNBC. "When a question is entered, the search results show a gray bubble directly under the search bar, offering more human-like responses than typical search results." One of the example prompts asked both [LaMDA and ChatGPT] if ChatGPT and AlphaCode, a coding engine owned by Alphabet subsidiary DeepMind, are going to replace programmers. "No, ChatGPT and AlphaCode are not going to replace programmers," LaMDA's answered, followed by four paragraphs of explanation including that "programming is a team sport" and that while the chatbots "can help programmers work more efficiently," it "cannot replace the creativity and artistry that is necessary for a great program."

ChatGPT's response was similar, stating "It is unlikely that ChatGPT or Alphacode will replace programmers" because they are "not capable of fully replacing the expertise and creativity of human programmers...programming is a complex field that requires a deep understanding of computer science principles and the ability to adapt to new technologies."

PayPal unveiled plans Tuesday to cut 2,000 employees, becoming the latest U.S. company to reduce its headcount, just hours after software company HubSpot announced it would lay off 500 positions in an effort to reduce costs as the company struggles from a "perfect storm" of inflation, tight customer budgets and "volatile foreign exchange." Forbes reports: In a statement on Tuesday, online payment company PayPal announced it would cut 7% of its global workforce (2,000 full-time positions) amid a "competitive landscape" and a "challenging macro-economic environment," CEO Dan Schulman said.

HubSpot, a Cambridge, Massachusetts-based software company, said it would cut 7% of its workforce by the end of the first quarter of 2023 in a Securities and Exchange Commission filing, as part of a restructuring plan, with CEO Yamini Rangan telling staff it follows a "downward trend" after the company "bloomed" in the Covid-19 pandemic, with HubSpot facing a "faster deceleration than we expected." Yesterday, Philips said it would cut 3,000 jobs worldwide in 2023 and 6,000 total by 2025 after announcing $1.7 billion in losses for 2022. Spotify, IBM, Google, Microsoft, Amazon, and a slew of other tech companies announced layoffs in recent days/weeks as well.

A small asteroid is flying very close to Earth on Thursday night, less than a week after astronomers discovered the object. The New York Times reports: The asteroid, named 2023 BU, was scheduled to pass over the southern tip of South America at 7:27 p.m. Eastern time. The asteroid is fairly small -- less than 30 feet across, about the size of a truck -- and will be best visible in the skies to the west of southern Chile. For space watchers unable to view 2023 BU firsthand, the Virtual Telescope Project will be broadcasting the event on its website and YouTube channel. The asteroid will not hit Earth but will make one of the closest approaches ever by such an object, hurtling past Earth at just 2,200 miles above its surface, according to a news release from the NASA Jet Propulsion Laboratory. This encounter puts the asteroid "well within the orbit of geosynchronous satellites," the statement noted, but the asteroid is not on track to hit any.

2023 BU was unknown to NASA, or anyone, until last Saturday. Gennadiy Borisov, an amateur astronomer in Crimea, noticed the asteroid from the MARGO Observatory, a setup of telescopes that he has used to discover other interstellar objects. Astronomers then determined 2023 BU's orbit around the sun and impending trip past Earth using data from the Minor Planet Center, a project sanctioned by the International Astronomical Union. It publishes positions of newly found space objects, including comets and satellites, from information of several observatories worldwide.

Consumer lending firm Capital One has cut 1,100 positions in its technology segment, Reuters is reporting citing a source familiar with the matter, a move that comes as its digital transformation matures. From the report: The company plans to eliminate its "Agile" job family and integrate it into existing engineering and product manager roles, it said in a statement. The affected employees have been invited to apply for other roles in the bank. "The Agile role in our Tech organization was critical to our earlier transformation phases but as our organization matured, the natural next step is to integrate agile delivery processes directly into our core engineering practices," the statement said.

Salesforce division Tableau was hit harder than other units in the company's largest-ever round of jobs cuts this week, adding to a major reorganization that signals the $15.7 billion acquisition hasn't lived up to expectations. Bloomberg reports: Chief Executive Officer Mark Nelson was ousted from the data analytics division in late December and more senior staff were axed Wednesday as part of Salesforce's announcement that it would eliminate 10% of its workforce. Job reductions at Tableau were greater, proportionally, than the company at large thus far. After a half-decade of fast hiring and large acquisitions, Salesforce is trying to cut costs and better integrate the companies it has purchased. The software maker, which lost almost half of its value in 2022, has been pressured by investors to improve profit. The job cuts made public Wednesday -- about 8,000 workers -- are less than half of the number of employees hired in the pandemic and followed the announced exit in December of co-CEO Bret Taylor and the elimination of hundreds of sales positions in November.

Acquisitions fueled the company's headcount growth. Tableau, then Salesforce's most expensive deal when it was bought in 2019, came with 4,200 employees while Slack, purchased in 2021, and Mulesoft, acquired in 2018, together brought another 3,700, according to company filings. The three deals combined cost almost $50 billion with the estimated $27.7 billion for Slack leading the way. Workers across these acquired divisions were pummeled by the job reductions, particularly in recruiting and customer success roles, according to company employees. Tableau is increasingly being treated as a visualization tool for data contained in Salesforce's other services rather than a standalone program -- co-founder and CEO Marc Benioff highlighted the new integrations in a December keynote speech. The division has trailed the rest of the company in sales growth since the acquisition.

Salesforce also plans to pare back its office footprint. The company currently has four offices in the Seattle area, more than any other city, according to the company website. Three were inherited in the Tableau deal. Salesforce declined to comment on whether it would be reducing space in the Seattle area. Asked about the effect of Wednesday's job cuts on Tableau, a Salesforce spokesperson said the unit "is a vital part of our product strategy." Tableau contributes to a product that "processes over 100 billion customer records, and helps our customers understand and act on their data," the spokesperson said.

Japan's decision to reignite its nuclear power industry is facing serious setbacks: 11 years of prohibition has led to a shortage of engineers, a lack of students training to fill vacant positions and a dearth of domestic nuclear manufacturing capability. The Register reports: The Japan Electrical Manufacturers' Association claims the number of "skilled engineers responsible for manufacturing nuclear equipment" has declined by 45 percent since the government banned nuclear power projects and shut existing reactors in response to the Fukushima meltdown in 2011. In addition, the JEMA said there are 14 percent fewer students in nuclear engineering programs at Japan's universities and graduate schools, the Financial Times reports. [...]

Japanese officials previously planned to phase out nuclear power entirely by 2030, but now hopes nearly a quarter of the country's power will come from nuclear sources by the end of the 2020s. According to NPR, that goal might be out of reach because it would require construction of an additional 17 reactors by 2030 -- a tough goal under the best of circumstances. Japan's reversal of the nuclear power ban didn't do anything to address supply shortages, NPR said. Add manpower shortages to that equation, and Japan's nuclear ambitions seem increasingly out of reach.

An anonymous reader quotes a report from Motherboard: Scientists at Brookhaven National Laboratory have uncovered an entirely new kind of quantum entanglement, a phenomenon that causes particles to become weirdly linked, even across vast cosmic distances, reports a new study. The discovery allowed them to capture an unprecedented glimpse of the bizarre world inside atoms, the tiny building blocks of matter. The mind-bending research resolves a longstanding mystery about the nuclei of atoms, which contain particles called protons and neutrons, and could help shed light on topics ranging from quantum computing to astrophysics. The exciting discoveries took place at the Relativistic Heavy Ion Collider (RHIC), a specialized facility at Brookhaven in New York that can accelerate charged atoms, known as ions, to almost light speed. When these ions collide -- or even just pass near each other -- their interactions expose the inner workings of atoms, which are governed by the trippy laws of quantum mechanics. [...]

Now, for the first time ever, scientists at Brookhaven have captured interference patterns that are created by the entanglement of two particles with different charges, a breakthrough that has opened up a completely new window into the mysterious innards of atoms that make up visible matter in the universe, according to a study published on Wednesday in Science Advances. "There's never been any measurement in the past of interference between distinguishable particles," said Daniel Brandenburg, a physics professor at the Ohio State University who co-authored the new study, in a call with Motherboard. "That's the discovery; the application is that we get to use it to do some nuclear physics." Brandenburg and his colleagues achieved this milestone with the help of a sensitive detector called the Solenoidal Tracker at RHIC, or STAR, that captured interactions between gold ions that were boosted to the brink of light speed. Clouds of photons, which are particles that carry light, surround the ions and interact with another type of particle, called gluons, that hold atomic nuclei together. These encounters between the photons and the gluons set off a chain of events that ultimately created two new particles, called pions, which have opposite charges -- one positive and one negative. When these pions careened into the STAR detector, the precision instrument measured some of their key properties, such as velocity and angle of impact, which were then used to probe the size, shape, and arrangement of gluons inside the atomic nuclei with a precision that has never been achieved before.

Scientists have imaged atomic nuclei at lower energies before, but attempts to probe these structures at high energies has always produced a puzzling result. Nuclei in these experiments look way bigger than they should, according to models, an outcome that has puzzled scientists for decades. Now, the STAR collaboration has now solved this mystery by pinpointing a blurring effect that is linked to the photons in the experiment. Essentially, past studies captured one-dimensional glimpses of nuclei that did not account for important patterns in photons, such as their polarization direction. The new study included this polarization information, allowing Brandenburg and his colleagues to probe the nuclei from two angles, parallel and perpendicular to the photon's motion, producing a two-dimensional view that matches theoretical predictions. What's more, the team is even able to make out the rough positions of key particles in the nucleus, such as protons and neutrons, as well as the distribution of gluons. It also offers a new way to unravel persistent mysteries about the behavior of atoms at high energies. [...] Brandenburg hopes to repeat this technique, and versions of it, at RHIC and other facilities like the Large Hadron Collider, in order to tease out the long-hidden details inside atomic nuclei.
