Long-time Slashdot reader HanzoSpam shares a report from Ars Technica: Frank Borman, an Air Force test pilot, astronaut, and accomplished businessman who led the first crew to fly to the Moon in 1968, died Tuesday in Montana, NASA said Thursday. He was 95 years old. Borman, joined by crewmates Jim Lovell and Bill Anders, orbited the Moon 10 times over the course of about 20 hours. They were the first people to see the Earth from another world, a memory of "wonderment" Borman recalled decades later. Apollo 8 produced one of the most famous photos ever taken, the iconic "Earthrise" showing a blue orb -- the setting for all of human history until then -- suspended in the blackness of space over the charcoal gray of the Moon's cratered surface.

Borman was born in Gary, Indiana, on March 14, 1928, and raised in Tucson, Arizona. He learned to fly airplanes as a teenager, then attended the US Military Academy at West Point before earning his commission in the Air Force to start training as a fighter pilot. Following a similar career path as other early astronauts, Borman became an experimental test pilot, receiving a master's degree in aeronautical engineering from Caltech, and served a stint as an assistant professor at West Point. NASA accepted applications for a second class of astronauts in 1962 to follow the original Mercury Seven. Borman was one of the "New Nine" astronauts, and he reported for training in Houston. "Today we remember one of NASA's best," NASA Administrator Bill Nelson said in a statement. "Astronaut Frank Borman was a true American hero. Among his many accomplishments, he served as the commander of the Apollo 8 mission, humanity's first mission around the Moon in 1968."

According to Nikkei Asia (paywalled), Indonesia has officially launched Southeast Asia's largest floating solar plant. It covers an area of over 250 hectares (2.5 km^2) and should be able to produce enough renewable energy to power 50,000 homes. Interesting Engineering reports: "Today is a historical day because our big dream of building a large-scale renewable energy plant is finally achieved. We managed to build the largest floating solar plant in Southeast Asia, and the third biggest in the world," Widodo is reported to have said at the opening ceremony. "The Cirata floating solar panel is the largest floating solar panel in Southeast Asia, and also the third largest in the world," he added.

China's PowerChina Huadong Engineering Corporation Limited constructed the power plant with Indonesia's state electricity corporation PLN and the United Arab Emirates energy company Masdar. The project had an investment of $145 million. More than 340,000 solar panels cover the reservoir surface, generating 192 MW of electricity annually, complementing existing hydropower at the site. The project had experienced significant delays before construction finally commenced in December 2020. [...]

PLN and Masdar are discussing plans to expand the facility and increase its power generation capacity to 500 MW. The plant occupies only 4% of the dam's reservoir surface, and according to the Indonesian government, solar panels can occupy up to 20% of the surface of a lake or dam, making it an efficient use of space.

The U.S. Space Force's shadowy X-37B spaceplane is set to launch atop a SpaceX Falcon Heavy rocket on Dec. 7. It'll mark the seventh mission for the X-37B, but the first time it'll fly on a heavy-lift launcher. Space.com reports: Little is known about the capabilities and operations of the space plane, but Space Force says the mission will follow previous flights that used the X-37B as a test bed for launching experimental payloads and returning them to Earth. "We are excited to expand the envelope of the reusable X-37B's capabilities, using the flight-proven service module and Falcon Heavy rocket to fly multiple cutting-edge experiments for the Department of the Air Force and its partners," said Lt. Col. Joseph Fritschen, program director for the X-37B, in the statement.

It isn't known why the X-37B is launching atop a Falcon Heavy for the USSF-52 mission. Five of the space plane's previous missions launched on United Launch Alliance Atlas V rockets, while its fifth mission, USA-277, took off on top of SpaceX's smaller rocket, the Falcon 9 (Falcon Heavy consists of three Falcon 9 boosters strapped together). Such a change could suggest that the space plane is carrying heavier payloads or is sporting a new hardware configuration. So far, Space Force has only stated that the mission will "expand the United States Space Force's knowledge of the space environment by experimenting with future space domain awareness technologies," according to the statement. However, Space Force's statement adds that the mission will carry a NASA experiment known as Seeds-2 that will test the effects that space-based radiation has on plant seeds during a long-duration spaceflight.

An anonymous reader quotes a report from Ars Technica: People who buy a Fire TV from Amazon are probably looking for a cheap and simple way to get an affordable 4K smart TV. When Amazon announced its first self-branded TVs in September 2021, it touted them as being a "great value." But owners of the devices will soon be paying for some of those savings in the form of more prominently displayed advertisements. Charlotte Maines, Amazon's director of Fire TV advertising, monetization, and engagement, detailed the new types of ads that Amazon is selling on Fire TVs. In a StreamTV Insider report from November 1, Amazon said the new ads will allow advertisers to reach an average of 155 million unique monthly viewers. Some of the changes targeting advertisers, like connecting display placement ads with specific in-stream video ads, seem harmless enough. Others could jeopardize the TV-watching experience for owners.

For example, Amazon is preparing to make Alexa with generative AI more useful for finding content on Fire TVs. This could help Alexa, which has struggled alongside other tech giants' voice assistants to generate significant revenue. Amazon gets money every time someone interacts with digital content through Alexa. However, the company is double-dipping on this idea by also tying ads to generative AI on Fire TVs. When users ask Alexa to help them find media with queries such as "play the show with the guy who plays the lawyer in Breaking Bad," they will see ads that are relevant to the search. [...] Finally, Amazon is adding "contextual sponsored tiles" that use machine learning to show ads based on whatever content genre or search term the Fire TV user is browsing.

Amazon Fire TV users will also start seeing banner ads on the device's home screen for things that have nothing to do with entertainment or media. This ad space was previously reserved for advertising media and entertainment, making the ads feel more relevant, at least. Amazon opening the ad space to more types of advertisers is similar to a move Google TV made early this year. The banner ads will occupy the first slot in the rotating hero area, which Amazon believes is the first thing Fire TV users see.

AmiMoJo shares a report from the BBC: Europe's Euclid telescope is ready to begin its quest to understand the greatest mysteries in the Universe. Exquisite imagery from the space observatory shows its capabilities to be exceptional. Over the next six years, Euclid will survey a third of the heavens to get some clues about the nature of so-called dark matter and dark energy. The 1.4 billion euro Euclid telescope went into space in July. Since then, engineers have been fine-tuning it. There were some early worries. Initially, Euclid's optics couldn't lock on to stars to take a steady image. This required new software for the telescope's fine guidance sensor. Engineers also found some stray light was polluting pictures when the observatory was pointed in a certain way. But with these issues all now resolved, Euclid is good to go -- as evidenced by the release of five sample images on Tuesday. "No previous space telescope has been able to combine the breadth, depth and sharpness of vision that Euclid can," notes the BBC. "The astonishing James Webb telescope, for example, has much higher resolution, but it can't cover the amount of sky that Euclid does in one shot."

Flexible office-space firm WeWork has filed for Chapter 11 bankruptcy protection, listing over $18.6 billion of debts in a remarkable collapse for the once high-flying startup co-founded by Adam Neumann and bankrolled by SoftBank, BlackRock and Goldman Sachs. From a report: The New York-based firm, which raised over $22 billion and was valued at $47 billion at its peak, has listed assets of over $15 billion in the petition it filed in a New Jersey federal court.

WeWork chief executive David Tolley said about 90% of the company's lenders have agreed to convert their $3 billion of debt into equity. WeWork's bankruptcy filing is limited to locations in the U.S. and Canada, it said. WeWork India has emerged as one of the strongest units in the WeWork franchise, and is largely insulated from the bankruptcy as majority of it is owned by Embassy Group. The India unit makes money and doesn't need external capital to operate, the India head said in a statement today.

There's now two million subscribers to SpaceX's Starlink satellite internet service, with CEO Elon Musk announcing Thursday that it has "achieved breakeven cash flow..."

Long-time Slashdot reader SonicSpike shared this report from CNBC: Musk did not specify whether that milestone was hit on an operating basis or for a specified time period. Earlier this year, SpaceX President and Chief Operating Officer Gwynne Shotwell said Starlink "had a cash flow positive quarter" in 2022, and the overall SpaceX company reportedly turned a profit in the first quarter of 2023.

SpaceX's valuation has soared to about $150 billion, with Starlink seen as a key economic driver of the company's goals. Two years ago, Musk emphasized that making Starlink "financially viable" required crossing "through a deep chasm of negative cash flow."

Musk has discussed spinning off Starlink to take it public through an initial public offering once the business was "in a smooth sailing situation." But timing of a Starlink IPO remains uncertain. Last year, Musk told employees that taking the business public wasn't likely until 2025 or later.

Scientists recently noticed that the chemical fingerprint of meteor particles was starting to change.

And last month Purdue University announced that "The Space Age is leaving fingerprints on one of the most remote parts of the planet — the stratosphere — which has potential implications for climate, the ozone layer and the continued habitability of Earth." Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet's surface, researchers have discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. That mass of metal is changing atmospheric chemistry in ways that may impact Earth's atmosphere and ozone layer...

Led by Dan Murphy, an adjunct professor in Purdue's Department of Earth, Atmospheric, and Planetary Sciences and a researcher at the National Oceanic and Atmospheric Administration, the team detected more than 20 elements in ratios that mirror those used in spacecraft alloys. They found that the mass of lithium, aluminum, copper and lead from spacecraft reentry far exceeded those metals found in natural cosmic dust. Nearly 10% of large sulfuric acid particles — the particles that help protect and buffer the ozone layer — contained aluminum and other spacecraft metals.

Ars Technica reports: In three-and-a-half years of service, one of SpaceX's reusable Falcon 9 boosters stands apart from the rest of the company's rocket inventory. This booster, designated with the serial number B1058, has now flown 18 times.

For its maiden launch on May 30, 2020, the rocket propelled NASA astronauts Doug Hurley and Bob Behnken into the history books on SpaceX's first mission to send people into orbit. This ended a nine-year gap in America's capability to launch astronauts into low-Earth orbit and was the first time a commercial spacecraft achieved this feat... Over the course of its flights to space and back, that white paint has darkened to a charcoal color. Soot from the rocket's exhaust has accumulated, bit by bit, on the 15-story-tall cylinder-shaped booster. The red NASA worm logo is now barely visible.

On Friday night, this rocket launched for the 18th time, breaking a tie at 17 flights with another Falcon 9 booster in SpaceX's fleet... It fired three engines for a braking burn to slow for reentry, then ignited a single engine and extended four carbon-fiber landing legs to settle onto a floating platform holding position near the Bahamas. The drone ship will return the rocket to Cape Canaveral, where SpaceX will refurbish the vehicle for a 19th flight.
Other interesting statistics from the article:

• This single booster rocket has launched 846 satellites into space. (Astrophysicist/spaceflight tracker Jonathan McDowell calculates there are now over 5,000 Starlink satellites in orbit.)

• A SpaceX official told Ars Technica the company might extend the limit on Falcon 9 booster flights beyond 20 for Starlink satellites.

• Friday's launch became the 79th launch so far in 2023 of a Falcon rocket, with SpaceX aiming for a total of 100 by the end of December, and 144 in 2023 (an average of one flight every two-and-a-half days).

• Since 2016, SpaceX has now had 249 consecutive successful launches of its Falcon 9 and Falcon Heavy rockets

Long-time Slashdot reader thepacketmaster writes: Documented in a recent article in the journal Nature, researchers have found an abundance of both helium-4 and helium-3 trapped in the volcanic rocks on Canada's Baffin Island.

As the Earth formed, it is thought that helium-4 and helium-3 flowing on the solar wind became trapped in the minerals of the cooling planet. With heavier elements and minerals sinking to the bottom, this trapped helium was transported to the core, where it would have remained locked in its original forms.

Earth isn't massive enough to hold on to helium in any significant quantities, though. Any that did not get trapped, or that was subsequently released when the minerals melted in the mantle or due to massive impacts, would have eventually seeped up to the surface and floated off into space. So, helium is relatively rare on Earth, and helium-3 is even more so.

During a close flyby of the asteroid Dinkinesh, NASA's Lucy spacecraft discovered a mini moon a mere one-tenth-of-a-mile (220 meters) in size. For comparison, Dinkinesh is barely a half-mile (790 meters) across. The Associated Press reports: NASA sent Lucy past Dinkinesh as a rehearsal for the bigger, more mysterious asteroids out near Jupiter. Launched in 2021, the spacecraft will reach the first of these so-called Trojan asteroids in 2027 and explore them for at least six years. The original target list of seven asteroids now stands at 11. Dinkinesh means "you are marvelous" in the Amharic language of Ethiopia. It's also the Amharic name for Lucy, the 3.2 million-year-old remains of a human ancestor found in Ethiopia in the 1970s, for which the spacecraft is named.

Jeff Foust reports via SpaceNews: A NASA official opened the door to keeping the International Space Station in operation beyond 2030 if commercial space stations are not yet ready to take over by the end of the decade. Speaking at the Beyond Earth Symposium here Nov. 2, Ken Bowersox, NASA associate administrator for space operations, said it was "not mandatory" to retire the ISS as currently planned at the end of the decade depending on the progress companies are making on commercial stations. "The timeline is flexible," he said of that transition from the ISS to commercial stations. "It's not mandatory that we stop flying the ISS in 2030. But, it is our full intention to switch to new platforms when they're available." [...]

Bowersox acknowledged that schedule depends on the readiness of those commercial stations. "When it happens is going to depend a lot the maturity of the market," he said, which includes both the status of commercial stations and non-NASA customers for them. He made it clear that NASA does not expect to be the only customer for commercial stations. NASA's current requirements for those stations anticipate having two astronauts at a time on them, less than the ISS. "We looked at what we thought would be reasonable and what would actually give us a cost savings," he said of that requirement. "My biggest concern is if we get too far ahead of where the market and NASA has to carry the full cost of the platforms for longer, and we transition too quickly," he said. That could force NASA to move money from current ISS utilization to support those stations. "If we have a badly managed transition, we could find ourselves getting weak in those areas."

An anonymous reader quotes a report from the New York Times: Ken Mattingly, who orbited the moon and commanded a pair of NASA shuttle missions, but who was remembered as well for the flight he didn't make -- the near-disastrous mission of Apollo 13 -- died on Tuesday in Arlington, Va. He was 87. His death was confirmed by Cheryl Warner, a NASA spokeswoman. She did not specify the cause or say whether he died at home in Arlington or in a hospital there. Mr. Mattingly, a former Navy jet pilot with a degree in aeronautical engineering, joined NASA in 1966. But his first spaceflight didn't come until April 1972, when the space agency launched Apollo 16, the next-to-last manned mission to the moon. Piloting the spacecraft's command module in orbit while holding the rank of lieutenant commander, he took extensive photos of the moon's terrain and conducted experiments while Cmdr.John W. Young of the Navy and Lt. Col. Charles M. Duke Jr. of the Air Force, having descended in the lunar lander, collected rock and soil samples from highlands near the crater known as Descartes.

While the three astronauts were en route back to Earth, Commander Mattingly stepped outside the spacecraft -- which he had named Casper for the resemblance, as least in a child's eye, between an astronaut in a bulky spacesuit and the cartoon character Casper the Friendly Ghost. Maneuvering along handrails while connected to the spacecraft by a tether, he retrieved two attached canisters of film with photos of the moon that he had taken from inside the capsule for analysis back on Earth. When the Apollo program ended, Commander Mattingly headed the astronaut support office for the shuttle program, designed to ferry astronauts to and from an eventual Earth-orbiting International Space Station. In the summer of 1982, he commanded the fourth and final Earth-orbiting test flight of the shuttle Columbia, which completed 112 orbits. He was also the commander of the first space shuttle flight conducted for the Department of Defense, a classified January 1985 mission aboard Discovery.

All those achievements came after he had been scrubbed at virtually the last moment from the flight of Apollo 13 in April 1970. He was to have orbited the moon in the command module while Cmdr.James A. LovellJr. of the Navy and Fred W. Haise Jr. explored the lunar surface. But NASA removed Commander Mattingly from the crew in the final days before launching, when blood tests determined that he had recently been exposed to German measles from training with Colonel Duke, the backup lunar module pilot, who in turn had contracted it from his proximity to an infected child at a neighborhood party. Commander Mattingly was the only one of the Apollo 13 crewmen who were found to lack antibodies against the illness. His backup, John L. Swigert Jr., became the command module pilot, leaving Commander Mattingly to watch the progress ofthe flight from mission control. [...] After his Apollo and space shuttle flights, Mr. Mattingly continued to work for NASA in the 1980s. He retired from the space agency and the Navy as a rear admiral and went on to work for aerospace companies.

Alphabet's Google and property developer Lendlease Group have ended an agreement to build four projects in the San Francisco Bay Area as the technology firm reviews its real estate footprint. From a report: Lendlease said it will be compensated for its work during the planning process for the projects, which are located in San Jose, Sunnyvale and Mountain View, according to a statement Thursday. "The decision to end these agreements followed a comprehensive review by Google of its real estate investments, and a determination by both organizations that the existing agreements are no longer mutually beneficial given current market conditions," Sydney-based Lendlease said in the statement.

The projects would have totaled more than 15 million square feet (1.4 million square meters) of office, residential, retail, hospitality and community development space. The projects were also slated to bring more housing to California's tight residential market. Google still plans to work with developers and capital partners to move the projects forward, according to a spokesperson. "As we've shared before, we've been optimizing our real estate investments in the Bay Area, and part of that work is looking at a variety of options to move our development projects forward and deliver on our housing commitment," Alexa Arena, a senior director of development at Google, said in an emailed statement.

In response to studies that relate high rates of female attrition from biomedical research fields to the obligations of motherhood, researchers concerned about inclusivity are now debating the issue of weekend conference duties. Nature: Because published findings are often old news in the rapidly changing biomedical fields, in-person conferences offer a crucial opportunity for scientists to stay current on trends that shape projects and funding outcomes. Yet fields often expect rock-star-like travel schedules on an economy-class budget in addition to long, irregular weekday hours at the laboratory. This is why early-career scientists with children say that they must seek alternative childcare or risk being scooped or excluded from a collaboration simply because they missed a weekend conference.

International meetings are often scheduled over weekends because that's the only time venues have availability. Few cities have both suitable venues and enough hotel space to welcome 21,000 people from around the world, and even meetings for 3,000 researchers must be booked many years in advance. Because local businesses and regional associations tend to book venues during the working week, large meetings that span three to five days often need to start or end over a weekend. Women who continue to break the glass ceiling in biomedicine are now pitching this timing as an example of unnecessary conflict between work and family.

At Apple's "Scary Fast" event today, the company unveiled a refreshed 24-inch iMac, entry-evel MacBook Pro that ditches the Touch Bar, and its latest "M3" in-house chips. The Verge reports: As expected, Apple's M3 chips took the spotlight during this month's event. The new lineup includes the M3, M3 Pro, and M3 Max chips, which Apple says mark the "first personal computer chips" made using the more efficient 3-nanometer process. In addition to offering a "faster and more efficient CPU," the trio of chips comes with an updated GPU that supports ray tracing, mesh shading, and Dynamic Caching -- a feature that optimizes the amount of memory the device uses during tasks. Apple's M3 chips offer up to 128GB of unified memory, with the most powerful M3 Max chip coming with up to 92 billion transistors, a 40-core GPU, and a 16-core CPU.

The new 24-inch iMac is getting an M3-flavored upgrade that Apple says offers two times faster performance than its M1-equipped predecessor. Along with the new chip, the refreshed iMac features a 4.5K Retina display with more than 1 billion colors, support for Wi-Fi 6E, and a 1080p webcam. The iMac also offers up to 24GB of unified memory and comes in seven colors: green, yellow, orange, pink, purple, blue, and silver. There are also color-matched accessories that come with the iMac, but they still feature Lightning connectors. The 24-inch iMac costs $1,299 with an eight-core CPU or $1,499 with a 10-core chip. You can preorder it starting today, with availability starting on November 7th.

Alongside the M3 Pro and M3 Max-equipped MacBook Pro models, Apple is releasing a cheaper 14-inch MacBook Pro that comes with the base M3 chip and starts at $1,599. The device replaces the 13-inch MacBook Pro with an M2 chip that Apple released last year and offers performance that's up to 60 percent faster. The Touch Bar model is being discontinued, which means it's all physical keys from here out. There are some drawbacks to this entry-level model, though: it features a meager 8GB of RAM and comes in just silver and space gray variations -- the black color is exclusive to the higher-end MacBook Pros. The device is available to preorder today and officially launches on November 7th.

An anonymous reader quotes a report from TorrentFreak: Brazil's telecoms regulator Anatel claims that during an operation last week, it successfully blocked around 80% of pirate 'TV boxes' in the country. Estimates from early 2023 suggest that seven million were active in Brazil. The operation, claimed to be the most significant ever carried out, arrives just weeks after Google & Cisco were criticized for "turning a blind eye" to the IPTV piracy problem. [...] Whatever the approach, if Anatel had somehow managed to prevent 80% of all TV boxes receiving pirated content in the space of a year, that would be an extraordinary achievement. Even a week would be astonishing but the claim of millions in a day seems either incredible, non-credible, or entirely dependent on more important information or nuance that isn't being reported. Another angle is that disruption on a large scale tends to register in search results and Google data on various related search terms doesn't seem to reflect millions of TV boxes suddenly going dark in Brazil last week. At least, not for any significant length of time.

Wikipedia defines LIGO as "a large-scale physics experiment and observatory designed to detect cosmic gravitational waves." (It stands for Laser Interferometer Gravitational-Wave Observatory — that is, measuring the interference caused by superimposed waves.)

Now Science Alert reports: A technique for squeezing light in the arms of LIGO's interferometer has allowed its measurements to cross the quantum barrier.

For LIGO, it's a bold new realm of sensitivity, giving the gravitational wave detector the ability to find 60% more dead star mergers than the rate of its previous run, which was around one or two detections every week or so... "Now that we have surpassed this quantum limit, we can do a lot more astronomy," says physicist Lee McCuller of Caltech...

LIGO's sensitivity was already absolutely jaw-dropping. The interferometer works by detecting ripples in space-time that are generated by colliding black holes and neutron stars, millions of billions to light-years away. These cause gravitational waves, like ripples in a pond. We can't feel them; but they can be detected in miniscule deviations in the path of light down a long, long tunnel. These deviations are incredibly small, down to trillions of times smaller than a human hair. But once you get into subatomic scales — the quantum realm — LIGO's abilities are hobbled. That's because, on those unimaginably small scales, particles randomly pop in and out of space, creating a constant background hiss of quantum noise that's louder than any signal.

Frequency-dependent squeezing is a way of amplifying the signals to be 'louder' than the quantum noise... If you pinch a property of light, such as amplitude (or power), other properties, such as frequency, can be measured more accurately... [T]he light can be squeezed in multiple ways to amplify the frequency of the gravitational waves the scientists are looking for... "We've known for a while how to write down the equations to make this work, but it was not clear that we could actually make it work until now. It's like science fiction," says physicist Rana Adhikari of Caltech...

This means we're likely to see a significant uptick in the number of black hole and neutron star collisions we observe out there in the wider Universe.

Long-time Slashdot reader destinyland writes: In 1994 the TV show Friends premiered, and its first season's high ratings made it the 8th most-popular show. The next year Microsoft released Windows 95 — and filmed a promotional video for it with 25-year-old Matthew Perry and 26-year-old Jennifer Aniston.

"They'll be taking you on an adventure in computing that takes place in the office of Microsoft chairman Bill Gates," explains the video's narrator, adding "Along the way, they meet a wacky bunch of propellor-heads.... And are introduced the top 25 features of Windows 95!"

It's a journey back in time. (At one point the video refers to Windows as the operating system "with tens of millions of users.") Their 30-minute segment — billed as "the world's first cyber sitcom" — appears in an hour-long video introducing revolutionary features like the new "Start" button. Also demonstrated in Excel are the new minimize and maximize "features" in "the upper right-side of the window". And the two actors marvel at the ability to type a filename that was longer than eight characters...

Watch for reminders that The Microsoft Windows 95 Video Guide was filmed nearly three decades ago. When the desktop appears after waking from screensaver mode, Perry notes that there's "no messy DOS build-up." And later the video reminds viewers that Windows 95 is compatible "with DOS games like Flight Simulator." There's also a brand new feature called "Windows Explorer" (which is described as "File Manager on steroids"), as well as a new "Find" option, and a brand new icon named "My Computer". And near the end they pay a visit to the Microsoft Network — which was mostly a "walled garden" online service — described in the video as "your on-ramp to the information superhighway".

The video even explains how Windows 95 "uses the right mouse button for what Microsoft calls power users."

And by the end of it, Jennifer Anniston finds herself playing Space Cadet 3D pinball.

"Scientists recently fired up the world's smallest particle accelerator for the first time," reports Space.com.

"The tiny technological triumph, which is around the size of a small coin, could open the door to a wide range of applications, including using the teensy particle accelerators inside human patients." The new machine, known as a nanophotonic electron accelerator (NEA), consists of a small microchip that houses an even smaller vacuum tube made up of thousands of individual "pillars." Researchers can accelerate electrons by firing mini laser beams at these pillars. The main acceleration tube is approximately 0.02 inches (0.5 millimeter) long, which is 54 million times shorter than the 16.8-mile-long (27 kilometers) ring that makes up CERN's Large Hadron Collider (LHC) in Switzerland — the world's largest and most powerful particle accelerator... The inside of the tiny tunnel is only around 225 nanometers wide. For context, human hairs are 80,000 to 100,000 nanometers thick, according to the National Nanotechnology Institute.

In a new study, published Oct. 18 in the journal Nature, researchers from the Friedrich-Alexander University of Erlangen-Nuremberg (FAU) in Germany used the tiny contraption to accelerate electrons from an energy value of 28.4âkiloelectron volts to 40.7âkeV, which is an increase of around 43%. It is the first time that a nanophotonic electron accelerator, which was first proposed in 2015, has been successfully fired, the researchers wrote in a statement...

"For the first time, we really can speak about a particle accelerator on a [micro]chip," study co-author Roy Shiloh, a physicist at FAU, said in the statement.
What they accomplished "was demonstrated almost simultaneously by colleagues at Stanford University," according to the researchers' statement. "Their results are currently under review, but can be viewed on a repository. The two teams are working together on the realization of the 'Accelerator on a chip' in a project funded by the Gordon and Betty Moore Foundation" in 2015.
