Data Center Backup Generator Kicks In During Power Outage and Catches Fire (theregister.com) 13

Joe_Dragon shares a report from The Register: A power outage kicked off a fire in web hosting biz WebNX's Ogden data center in Utah on Sunday, knocking the facility offline temporarily and leaving several servers in need of a rebuild. Kevin Brown, Fire Marshal for the US city's Fire Department told The Register in a phone interview that firefighters responded to a call on Sunday evening. The fire, he said, "originated in a generator in the building and spread to several servers." Brown said the facility's fire suppression system contained the blaze and that fire department personnel assisted with the cleanup. He said power was cut to the building until an electrical engineer could inspect the facility to make sure current could be restored safely, which he added is standard procedure. He also confirmed that some of Ogden City's IT services were down on Sunday and Monday as a result of the data center fire. "Sunday afternoon the city power was disrupted and, as designed, our backup generators automatically switched on," the company said in a Facebook post. "However, during that transition, one of our backup generators that had been recently tested and benchmarked specifically for this situation experienced a catastrophic failure, caught fire, and as a result initiated the fire suppression protocol."

"Some servers will have an extended outage as they may require rebuilds due to some water damage. Those builds have a high probability that data is intact." They added: "Customer's servers in one of our main bays were exposed to water and possible damage may have occurred. No fire damage was inflicted on customer servers."

Glass Molded Like Plastic Could Usher In New Era of Complex Glass Shapes (sciencemag.org) 18

sciencehabit shares a report from Science Magazine: The production of glass -- one of humanity's oldest materials -- is getting a 21st century makeover. A new approach to glassmaking treats the material like plastic, allowing scientists to injection mold vaccine vials, sinuous channels for carrying out lab chemistry, and other complex shapes.

The scientists created a printable powder by mixing silica nanoparticles with a polymer that could be cured with ultraviolet (UV) light. After printing the shapes they wanted, they cured the polymer with UV light so it would hold its shape. They then fired the mix in an oven to burn off the polymer and fuse the silica particles into a continuous glass structure. The approach worked, making it possible to craft shapes such as tiny pretzels and replica castle gates. The work garnered interest from companies wanting to build minute lenses and other complex transparent optical components for telecommunications equipment. But the procedure was slow, turning out components one by one, rather than a fully industrial approach that could produce parts en masse, as is done with plastic.

To speed things up, [the researchers] have now extended their nanocomposite approach to work with injection molding, a process used to mass produce plastic parts like toys and car bumpers by the ton. The researchers again started with tiny silica particles. The team then mixed the silica with two polymers, polyethylene glycol (PEG) and polyvinyl butyral (PVB). The mixture created a dry powder with the consistency of toothpaste. The team fed the paste into an extruder that pressed it into a preformed mold with shapes such as a disc or tiny gear. To harden them, the researchers used water to wash away the PEG. They then fired the remaining material in two stages: First at 600C to burn out the PVB, and second at 1300C to fuse the silica particles into the final piece. Outside of the mold, the parts hold their shape because myriad weak attractive bonds, called van der Waals interactions, form between neighboring silica particles. But the parts are still fragile.
The report has been published in the journal Science.

US Arrests Suspect Who Wanted To Blow Up AWS Data Center (therecord.media) 72

An anonymous reader quotes a report from The Record: The FBI has arrested on Thursday a Texas man who planned to blow up one of the Amazon Web Services (AWS) data centers in an attempt to "kill of about 70% of the internet." Seth Aaron Pendley, 28, of Wichita Falls, Texas, was arraigned in front of a Texas judge today and formally indicted with a malicious attempt to destroy a building with an explosive.

The US Department of Justice said Pendley was arrested on Thursday after he tried to acquire C-4 plastic explosives from an undercover FBI employee in Fort Worth, Texas. The FBI said they learned of Pendley's plans after the suspect confided in January 2021 via Signal, an encrypted communications app, to a third-party source about plans to blow up one of Amazon's Virginia-based data centers. The source alerted the FBI and introduced the suspect to the undercover agent on March 31.
"The suspect allegedly told an FBI agent that he wanted to attack Amazon's data center because the company was providing web servers to the FBI, CIA, and other federal agencies and that he hoped to bring down 'the oligarchy' currently in power in the United States," the report says.

Pendley could face up to 20 years in federal prison if he's found guilty and convicted.

New, Reversible CRISPR Method Can Control Gene Expression While Leaving DNA Sequence Unchanged (phys.org) 13

fahrbot-bot shares a report from Phys.Org: Over the past decade, the CRISPR-Cas9 gene editing system has revolutionized genetic engineering, allowing scientists to make targeted changes to organisms' DNA. While the system could potentially be useful in treating a variety of diseases, CRISPR-Cas9 editing involves cutting DNA strands, leading to permanent changes to the cell's genetic material. Now, in a paper published online in Cell on April 9, researchers describe a new gene editing technology called CRISPRoff that allows researchers to control gene expression with high specificity while leaving the sequence of the DNA unchanged.

The classic CRISPR-Cas9 system uses a DNA-cutting protein called Cas9 found in bacterial immune systems. The system can be targeted to specific genes in human cells using a single guide RNA, where the Cas9 proteins create tiny breaks in the DNA strand. Then the cell's existing repair machinery patches up the holes. Because these methods alter the underlying DNA sequence, they are permanent.

That's where the researchers saw an opportunity for a different kind of gene editor -- one that didn't alter the DNA sequences themselves, but changed the way they were read in the cell. This sort of modification is what scientists call 'epigenetic' -- genes may be silenced or activated based on chemical changes to the DNA strand. Epigenetic gene silencing often works through methylation -- the addition of chemical tags to to certain places in the DNA strand -- which causes the DNA to become inaccessible to RNA polymerase, the enzyme which reads the genetic information in the DNA sequence into messenger RNA transcripts, which can ultimately be the blueprints for proteins. With this new CRISPRoff technology, one can [express a protein briefly] to write a program that's remembered and carried out indefinitely by the cell.

TAE Technologies Claims Landmark In Fusion Energy, Sees Commercialization By 2030 (techcrunch.com) 62

TAE Technologies, a 20-year-old fusion energy technology developer, is claiming to have hit a milestone in the development of a new technology for generation power from nuclear fusion. The company said its reactors could be operating at commercial scale by the end of the decade, thanks to its newfound ability to produce stable plasma at temperatures over 50 million degrees (nearly twice as hot as the sun). TechCrunch reports: For TAE Technologies, the achievement serves as a validation of the life's work of Norman Rostoker, one of the company's co-founders who had devoted his life to fusion energy research and died before he could see the company he helped create reach its latest milestone. "This is an incredibly rewarding milestone and an apt tribute to the vision of my late mentor, Norman Rostoker," said TAE's current chief executive officer, Michl Binderbauer, in a statement announcing the company's achievement. "Norman and I wrote a paper in the 1990s theorizing that a certain plasma dominated by highly energetic particles should become increasingly better confined and stable as temperatures increase. We have now been able to demonstrate this plasma behavior with overwhelming evidence. It is a powerful validation of our work over the last three decades, and a very critical milestone for TAE that proves the laws of physics are on our side."

Rostoker's legacy lives on inside TAE through the company's technology platform, called, appropriately, "Norman." In the last 18 months that technology has demonstrated consistent performance, reaching over 50 million degrees in several hundred test cycles. Six years ago, the company had proved that its reactor design could sustain plasma indefinitely -- meaning that once the switch is flipped on a reaction, that fusion reaction can continue indefinitely. Now, the company said, it has achieved the necessary temperatures to make its reactors commercially viable. It's with these milestones behind it that TAE was able to raise an additional $280 million in financing, bringing its total up to $880 million and making it one of the best financed private nuclear fusion endeavors in the world.

Research Says Facebook's Ad Algorithm Perpetuates Gender Bias 64

New research from a team at the University of Southern California provides further evidence that Facebook's advertising system is discriminatory, showing that the algorithm used to target ads reproduced real-world gender disparities when showing job listings, even among equally qualified candidates. The Intercept reports: In fields from software engineering to sales to food delivery, the team ran sets of ads promoting real job openings at roughly equivalent companies requiring roughly the same skills, one for a company whose existing workforce was disproportionately male and one that was disproportionately female. Facebook showed more men the ads for the disproportionately male companies and more women the ads for the disproportionately female companies, even though the job qualifications were the same. The paper concludes that Facebook could very well be violating federal anti-discrimination laws. "We confirm that Facebook's ad delivery can result in skew of job ad delivery by gender beyond what can be legally justified by possible differences in qualifications," the team wrote.

Customs and Border Protection Paid $700,000 To Encrypted App Wickr (vice.com) 15

An anonymous reader quotes a report from Motherboard: U.S. Customs and Border Protection (CBP), part of the Department of Homeland Security, recently paid encrypted messaging platform Wickr over $700,000, Motherboard has found. The news highlights the value of end-to-end encryption to law enforcement, while other federal law enforcement agencies routinely lambast the technology for what they say results in visibility on criminals' activities "going dark."

The contract is related to "Wickr licenses and support," dates from September 2020, and totals at $714,600, according to public procurement records. Wickr is likely most well known for its free consumer app, which lets users send encrypted messages to one another, as well as make encrypted video and audio calls. The app also offers an auto-burn feature, where messages are deleted from a users' device after a certain period of time, with the company claiming these messages "can never be uncovered," according to its website. Wickr also offers various paid products to private companies and government agencies. Wickr Pro and Wickr Enterprise are marketed towards businesses; Wickr RAM is geared specifically for the military. [...] It is not clear which specific Wickr product CBP paid for.
A CBP spokesperson told Motherboard in a statement that "The Federal Acquisition Regulations (FAR) and other laws prohibit the unauthorized use and disclosure of proprietary information from federal government contract actions. All publicly available information on this contract has been made available at the link you have provided. Any other information is considered proprietary to the awardee (WICKR) and shall not be divulged outside of the Government."

300 Nvidia GPUs Seized After High Speed Boat Chase (extremetech.com) 21

ExtremeTech's Joel Hruska tells the story of a recent high-speed boat chase involving up to 300 Nvidia CMP 30HX GPUs. From the report: Our movie-like story kicked off with Chinese authorities detaining a fishing boat anchored near Hong Kong International Airport. Men on the fishing boat were swapping cargo over to a speedboat. When authorities approached, the smugglers hopped into the speedboat and fled. While the customs officials were unable to apprehend the smugglers in the subsequent high-speed chase, the hapless fishing boat owner was unable to get away. Confiscated goods, according to THG, included sea cucumbers, shark fins, and other various tech products and gadgets. The graphics cards were considered a surprise.

There's a certain dark hilarity in imagining drug dealers across the world offering their clientele multiple ounces of weed or an RTX 3060, but in this case, the haul consisted of low-end 30HX CMP cards. Nvidia offers a range of CMP cards, with performance ranging from 26MH/s to 86MH/s. The 30HX and 40HX are believed to be based on Turing silicon -- the GTX 1660 Super and RTX 2070, respectively. The 50X and 90HX are harder to pin down. The 50HX is a touch faster than the known mining performance of the RTX 2080 Ti, while the 90HX is about 10 percent slower than the known mining performance of an RTX 3080. If the 50HX is based on the RTX 2080 Ti, it's fielding a smaller amount of VRAM; the RTX 2080 Ti offered 11GB, while the 50HX has just 10GB.

Myanmar's Internet Suppression (reuters.com) 29

In Myanmar, the junta's intensifying crackdowns on protesters in the street are mirrored by its rising restrictions online. Reuters: In the early hours of Feb. 1, Myanmar's military seized power in a coup that has ignited months of mass protests. The military junta's security forces have since killed more than 550 civilians in crackdowns on the pro-democracy protesters, including children. To try to suppress protests, the junta has imposed increasing restrictions on internet access, culminating in a near total shutdown as of April 2. That has made it extremely difficult for people to access information, upload videos of protests, or organize. These tactics have also crippled businesses and limited access to medical information during the coronavirus pandemic. A Myanmar junta spokesperson did not respond to calls seeking comment. At a March 23 press conference, spokesperson Zaw Min Tun said the junta had no immediate plans to ease internet restrictions because violence was being provoked online.

Protesters in Myanmar, who asked to stay anonymous, told Reuters they were terrified about being shut off from the world, with no way to broadcast news of the protests or of the army's killings to those outside of Myanmar. "We Myanmar people are in the dark now," said one young protester. "News from Myanmar is going to disappear," another added. Governments around the world are increasingly using internet restrictions during political crises as a tool to limit free expression and hide human rights abuses, according to data from the digital rights organization Access Now. The U.N. Human Rights Council has condemned such intentional disruptions as a human rights violation. "Whenever the internet is shut down during such critical moments we would hear or document or see reports of human rights abuses, and that is what is happening in Myanmar," said Felicia Anthonio, a campaigner with Access Now. "The government is cracking down on protesters to ensure they do not let the rest of the world know what is happening." Since the coup, the junta has ordered telecom companies to carry out dozens of shutdowns. These shutdowns targeted mobile and wireless internet, which is the only available internet for most in the country.

Neuralink Releases Videos of Monkey Playing Pong With Its Brain 17

Rei writes: Having moved from pigs to rhesus macaques in pursuit of the goal of hopefully beginning human trials by the end of the year, Neuralink has continued their recruitment drive with a pair of videos showing their latest progress. In the first video, they show how they train the macaque to control a joystick with its mind, and how after associating the neural signals with intent, they can disconnect the joystick and the macaque continues to be able to operate the training interface solely through Neuralink. They then switch it over to controlling a cursor in Pong (picture-in-picture showing synapses here). Even with the game set to high speed and with the distraction of his banana-milkshake reward, the macaque puts out an impressive gaming performance.

Musk expects the first commercial product to enable a paralyzed person to interact with a smartphone faster than a healthy person using their thumbs. ["Later versions will be able to shunt signals from Neuralinks in brain to Neuralinks in body motor/sensory neuron clusters, thus enabling, for example, paraplegics to walk again," adds Musk. "The device is implanted flush with skull & charges wirelessly, so you look & feel totally normal."]

Critical Zoom Vulnerability Triggers Remote Code Execution Without User Input (zdnet.com) 11

An anonymous reader quotes a report from ZDNet: A zero-day vulnerability in Zoom which can be used to launch remote code execution (RCE) attacks has been disclosed by researchers. The researchers from Computest demonstrated a three-bug attack chain that caused an RCE on a target machine, and all without any form of user interaction. As Zoom has not yet had time to patch the critical security issue, the specific technical details of the vulnerability are being kept under wraps. However, an animation of the attack in action demonstrates how an attacker was able to open the calculator program of a machine running Zoom following its exploit. As noted by Malwarebytes, the attack works on both Windows and Mac versions of Zoom, but it has not -- yet -- been tested on iOS or Android. The browser version of the videoconferencing software is not impacted. Computest researchers Daan Keuper and Thijs Alkemade earned themselves $200,000 for this Zoom discovery, as it was part of the Pwn2Own contest.

In a statement to Tom's Guide, Zoom thanked the Computest researchers and said the company was "working to mitigate this issue with respect to Zoom Chat." In-session Zoom Meetings and Zoom Video Webinars are not affected. "The attack must also originate from an accepted external contact or be a part of the target's same organizational account," Zoom added. "As a best practice, Zoom recommends that all users only accept contact requests from individuals they know and trust."

Are You Confused by Scientific Jargon? So Are Scientists (nytimes.com) 39

Scientific papers containing lots of specialized terminology are less likely to be cited by other researchers. The New York Times reports: Polje, nappe, vuggy, psammite. Some scientists who study caves might not bat an eye, but for the rest of us, these terms might as well be ancient Greek. Specialized terminology isn't unique to the ivory tower -- just ask a baker about torting or an arborist about bracts, for example. But it's pervasive in academia, and now a team of researchers has analyzed jargon in a set of over 21,000 scientific manuscripts. They found that papers containing higher proportions of jargon in their titles and abstracts were cited less frequently by other researchers. Science communication -- with the public but also among scientists -- suffers when a research paper is packed with too much specialized terminology, the team concluded. These results were published Wednesday in Proceedings of the Royal Society B.

Jargon can be a problem, but it also serves a purpose, said Hillary Shulman, a communications scientist at Ohio State University. "As our ideas become more refined, it makes sense that our concepts do too." This language-within-a-language can be a timesaver, a way to precisely convey meaning, she said. However, it also runs the risk of starkly reminding people -- even some well-educated researchers -- that they aren't "in the know." "It's alienating," said Dr. Shulman.

In One Year a Billion Tons of Food Got Wasted (bloomberg.com) 96

There is something that the average person can do to slow down climate change, and it can be accomplished without leaving the house. Don't waste food. From a report: Some 931 million tons of it went to waste in 2019, according to the United Nations Environment Programme. Individual households were responsible for more than half of that, with the rest coming from retailers and the food service industry. New estimates show that about 17% of food available to consumers worldwide that year ended up being wasted. The matter is even more urgent when considered alongside another UN analysis that tracks the problem further up the supply chain, and shows 14% of food production is lost before it reaches stores. Waste is happening at every point, from the field to the dinner table.

Food waste and loss are responsible for as much as 10% of global emissions, according to the Intergovernmental Panel on Climate Change. If it were a country, this discard would rank third in the ranking of the world's sources of greenhouse gases, after China and the U.S. Among the most effective climate solutions, non-profit Project Drawdown ranks cutting food waste ahead of moving to electric cars and switching to plant-based diets. Thursday's UNEP report suggests the amount of food wasted by consumers could be about double the previous estimate. The analysis conducted by the UN's Food and Agriculture Organization in 2011 relied on data from fewer countries.

Drought in Taiwan Pits Chip Makers Against Farmers (nytimes.com) 46

smooth wombat writes: Chuang Cheng-deng's modest rice farm is a stone's throw from the nerve center of Taiwan's computer chip industry, whose products power a huge share of the world's iPhones and other gadgets. This year, Mr. Chuang is paying the price for his high-tech neighbors' economic importance. Gripped by drought and scrambling to save water for homes and factories, Taiwan has shut off irrigation across tens of thousands of acres of farmland. The authorities are compensating growers for the lost income. But Mr. Chuang, 55, worries that the thwarted harvest will drive customers to seek out other suppliers, which could mean years of depressed earnings. "The government is using money to seal farmers' mouths shut," he said, surveying his parched brown fields.

Officials are calling the drought Taiwan's worst in more than half a century. And it is exposing the enormous challenges involved in hosting the island's semiconductor industry, which is an increasingly indispensable node in the global supply chains for smartphones, cars and other keystones of modern life. Chip makers use lots of water to clean their factories and wafers, the thin slices of silicon that form the basis of the chips. And with worldwide semiconductor supplies already strained by surging demand for electronics, the added uncertainty about Taiwan's water supply is not likely to ease concerns about the tech world's reliance on the island and on one chip maker in particular: Taiwan Semiconductor Manufacturing Company.

More than 90 percent of the worldâ(TM)s manufacturing capacity for the most advanced chips is in Taiwan and run by TSMC, which makes chips for Apple, Intel and other big names. The company said last week that it would invest $100 billion over the next three years to increase capacity, which will likely further strengthen its commanding presence in the market. TSMC says the drought has not affected its production so far. But with Taiwan's rainfall becoming no more predictable even as its tech industry grows, the island is having to go to greater and greater lengths to keep the water flowing. In recent months, the government has flown planes and burned chemicals to seed the clouds above reservoirs. It has built a seawater desalination plant in Hsinchu, home to TSMC's headquarters, and a pipeline connecting the city with the rainier north. It has ordered industries to cut use. In some places it has reduced water pressure and begun shutting off supplies for two days each week. Some companies, including TSMC, have hauled in truckloads of water from other areas.

APKPure App Contained Malicious Adware, Say Researchers (techcrunch.com) 24

Security researchers say APKPure, a widely popular app for installing older or discontinued Android apps from outside of Google's app store, contained malicious adware that flooded the victim's device with unwanted ads. From a report: Kaspersky Lab said that it alerted APKPure on Thursday that its most recent app version, 3.17.18, contained malicious code that siphoned off data from a victim's device without their knowledge, and pushed ads to the device's lock screen and in the background to generate fraudulent revenue for the adware operators. But the researchers said that the malicious code had the capacity to download other malware, potentially putting affected victims at further risk.
