Boeing's Starliner Losses Top $2 Billion (spacenews.com) 43

After a $523 million charge on its CST-100 Starliner program in 2024, Boeing's total losses on the commercial crew vehicle now exceed $2 billion -- and there's still no clear timeline for its next flight. SpaceNews reports: In the company's 10-K annual filing with the U.S. Securities and Exchange Commission Feb. 3, Boeing said it took $523 million in charges on Starliner in 2024. The company blamed the losses on "schedule delays and higher testing and certification costs as well as higher costs for post certification missions."

The company had reported a $125 million charge in the second quarter and a $250 million charge in the third quarter. The company warned Jan. 23 it would take an additional loss in the fourth quarter but did not disclose a figure when it released its financial results five days later. The annual loss implies a $148 million loss in the fourth quarter.

The $523 million in charges is the most Boeing has recorded in a single year on Starliner, exceeding $489 million it reported in 2019. The company's cumulative charges on Starliner are now just over $2 billion. "Risk remains that we may record additional losses in future periods," the company stated in the 10-K filing.

NASA Plans Twitch Stream From ISS (theverge.com) 12

NASA is planning to host a live Twitch stream next week from the International Space Station (ISS). "The stream, which takes place on February 12th at 11:45AM ET on NASA's Twitch channel, will feature Don Pettit, an astronaut currently on the ISS, and Matt Dominick, who returned to Earth from the ISS in October," reports The Verge. From the report: The astronauts will discuss "daily life aboard the space station and the research conducted in microgravity" and viewers will be able to ask them questions, according to a blog post.

"This Twitch event from space is the first of many," Brittany Brown, director of the Office of Communications Digital and Technology Division at NASA Headquarters in Washington, says in the post. "We spoke with digital creators at TwitchCon about their desire for streams designed with their communities in mind, and we listened. In addition to our spacewalks, launches, and landings, we'll host more Twitch-exclusive streams like this one."

An Anonymous Investor Is Spending Millions To Make Underwater Homes 66

An anonymous reader quotes a report from The Guardian: Down an easy-to-miss turnoff on the A48 just outside Chepstow on the Welsh border, the gentle rumble of trucks, cranes and people at work mixes with birdsong in what is an otherwise peaceful rural setting. It is a crisp and sunny winter morning when I visit and, at first glance, the site appears to be little more than prefab containers and a car park. Yet, behind the scenes a group of men and women with expertise in diving, marine biology, technology, finance, construction and manufacturing are building something extraordinary. They have come together with a single mission statement: to make humans aquatic. Their project is called Deep (not The Deep) and the site was chosen after a global search for the perfect location to build and test underwater accommodation, which the project founders say will enable them to establish a "permanent human presence" under the sea from 2027.

So far, so crazy sounding. Yet Deep is funded by a single anonymous private investor with deep pockets who wants to put hundreds of millions of pounds (if not more) into a project that will "increase understanding of the ocean and its critical role for humanity," according to a Deep spokesperson. Its leadership team remains tight-lipped not only about the amount (they will only say it is substantially more than the 100 million pounds being invested into the Deep campus near Chepstow), but also about the investor's identity. Whoever is behind it, the size of the investment means that an ambitious-sounding idea appears to be swiftly becoming a reality.

[...] Mike Shackleford, Deep's chief operating officer, explains the thought process behind the project. "Back in the 1950s and 60s, there was a space race and an ocean race going on, and space won out. Space is tough to get to, but once you're up there, it's a relatively benign environment." The ocean is the opposite: it's fairly easy to get to the bottom, but once you're down there, "basically, everything wants to kill you," he jokes. "Yet, just about every oceanographer I've met says, 'You'd be shocked at how little we know about the ocean,'" Shackleford tells me. "So somebody has got to take those first steps to try to build some of the technology that will allow us to go down and study the ocean in situ." The idea of Deep's sentinels is that, initially, people will be able to stay inside for up to 28 days at a time -- though the hope is that this could one day be extended to months ... and beyond. "The goal is to live in the ocean, for ever. To have permanent human settlements in all oceans across the world," says Shackleford.

Grand Canyon-Sized Valleys On the Moon Formed Within 10 Minutes (space.com) 25

A new study reveals that two Grand Canyon-sized valleys were formed in less than 10 minutes by "floods of rocks traveling as fast as bullets," reports Space.com. From the report: Scientists analyzed the lunar canyons, named Vallis Schrodinger and Vallis Planck, to find that these huge valleys measure 167 miles long (270 kilometers) and nearly 1.7 miles (2.7 km) deep, and 174 miles long (280 km) and nearly 2.2 miles deep (3.5 km), respectively. In comparison, the Grand Canyon is 277 miles long (446 km) and is, at most, about 1.2 miles deep (1.9 km), the researchers noted. [...] This pair of lunar canyons represents two of many valleys radiating out from Schrodinger basin, a crater about 200 miles wide (320 km) that was blasted out of the lunar crust by a cosmic impact about 3.81 billion years ago. This structure is located in the outer margin of the moon's largest and oldest remaining impact crater, the South Pole-Aitken basin, which measures about 1,490 miles wide (2,400 km) and dates about 4.2 billion to 4.3 billion years old.

[...] The scientists estimate that rocky debris flew out from the impact at speeds between 2,125 to 2,860 miles per hour (3,420 to 4,600 km/h). In comparison, a bullet from a 9mm Luger handgun might fly at speeds of about 1,360 mph (2,200 km/h). The researchers suggest the energy needed to create both of these canyons would have been more than 130 times the energy in the current global inventory of nuclear weapons. "The lunar canyons we describe are produced by streams of rock, whereas the Grand Canyon was produced by a river of water," [said David Kring, a geologist at the Lunar and Planetary Institute of the Universities Space Research Association]. "The streams of rock were far more energetic than the river of water, which is why the lunar canyons were produced in minutes and the Grand Canyon produced over millions of years."
The findings have been published in the journal Nature.

Popular Linux Orgs Freedesktop, Alpine Linux Are Scrambling For New Web Hosting (arstechnica.com) 26

An anonymous reader quotes a report from Ars Technica: In what is becoming a sadly regular occurrence, two popular free software projects, X.org/Freedesktop.org and Alpine Linux, need to rally some of their millions of users so that they can continue operating. Both services have largely depended on free server resources provided by Equinix (formerly Packet.net) and its Metal division for the past few years. Equinix announced recently that it was sunsetting its bare-metal sales and services, or renting out physically distinct single computers rather than virtualized and shared hardware. As reported by the Phoronix blog, both free software organizations have until the end of April to find and fund new hosting, with some fairly demanding bandwidth and development needs.

An issue ticket on Freedesktop.org's GitLab repository provides the story and the nitty-gritty needs of that project. Both the X.org foundation (home of the 40-year-old window system) and Freedesktop.org (a shared base of specifications and technology for free software desktops, including Wayland and many more) used Equinix's donated space. [...] Alpine Linux, a small, security-minded distribution used in many containers and embedded devices, also needs a new home quickly. As detailed in its blog, Alpine Linux uses about 800TB of bandwidth each month and also needs continuous integration runners (or separate job agents), as well as a development box. Alpine states it is seeking co-location space and bare-metal servers near the Netherlands, though it will consider virtual machines if bare metal is not feasible.

CERN's Mark Thomson: AI To Revolutionize Fundamental Physics (theguardian.com) 96

An anonymous reader quotes a report from The Guardian: Advanced artificial intelligence is to revolutionize fundamental physics and could open a window on to the fate of the universe, according to Cern's next director general. Prof Mark Thomson, the British physicist who will assume leadership of Cern on 1 January 2026, says machine learning is paving the way for advances in particle physics that promise to be comparable to the AI-powered prediction of protein structures that earned Google DeepMind scientists a Nobel prize in October. At the Large Hadron Collider (LHC), he said, similar strategies are being used to detect incredibly rare events that hold the key to how particles came to acquire mass in the first moments after the big bang and whether our universe could be teetering on the brink of a catastrophic collapse.

"These are not incremental improvements," Thomson said. "These are very, very, very big improvements people are making by adopting really advanced techniques." "It's going to be quite transformative for our field," he added. "It's complex data, just like protein folding -- that's an incredibly complex problem -- so if you use an incredibly complex technique, like AI, you're going to win."

The intervention comes as Cern's council is making the case for the Future Circular Collider, which at 90km circumference would dwarf the LHC. Some are skeptical given the lack of blockbuster results at the LHC since the landmark discovery of the Higgs boson in 2012 and Germany has described the $17 billion proposal as unaffordable. But Thomson said AI has provided fresh impetus to the hunt for new physics at the subatomic scale -- and that major discoveries could occur after 2030 when a major upgrade will boost the LHC's beam intensity by a factor of ten. This will allow unprecedented observations of the Higgs boson, nicknamed the God particle, that grants mass to other particles and binds the universe together.
Thomson is now confident that the LHC can measure Higgs boson self-coupling, a key factor in understanding how particles gained mass after the Big Bang and whether the Higgs field is in a stable state or could undergo a future transition. According to Thomson: "It's a very deep fundamental property of the universe, one we don't fully understand. If we saw the Higgs self-coupling being different from our current theory, that that would be another massive, massive discovery. And you don't know until you've made the measurement."

The report also notes how AI is being used in "every aspect of the LHC operation." Dr Katharine Leney, who works on the LHC's Atlas experiment, said: "When the LHC is colliding protons, it's making around 40m collisions a second and we have to make a decision within a microsecond ... which events are something interesting that we want to keep and which to throw away. We're already now doing better with the data that we've collected than we thought we'd be able to do with 20 times more data ten years ago. So we've advanced by 20 years at least. A huge part of this has been down to AI."

Generative AI is also being used to look for and even produce dark matter via the LHC. "You can start to ask more complex, open-ended questions," said Thomson. "Rather than searching for a particular signature, you ask the question: 'Is there something unexpected in this data?'"

Boeing Acquires Spirit AeroSystems, While Boeing's 'Starliner' Unit Gets a New VP (yahoo.com) 35

Spirit Aerosystems builds aircraft components, including fuselages and flight deck sections for Boeing, according to Wikipedia. But now Boeing is set to acquire Spirit AeroSystems.

The aviation blog called Aviation Source News says the price tag was $4.7 billion, and opines that Boeing's move signals "a renewed focus on quality and supply chain stability" as Boeing "addresses lingering concerns surrounding its 737 program." Spirit's recent struggles with quality control and production delays have had a fallout effect for Boeing... By integrating Spirit's operations, Boeing can implement more stringent oversight and ensure consistent manufacturing processes. This move is a direct response to past quality lapses that have plagued the company and damaged its reputation. Beyond quality control, the acquisition also offers Boeing greater control over its supply chain. By bringing a key supplier in-house, Boeing can streamline production, improve coordination, and reduce the risk of future disruptions...

Spirit AeroSystems also supplies parts to Airbus, Boeing's main competitor. To address this, a separate agreement is being negotiated for Airbus to acquire Spirit's Airbus-related business. This strategic move ensures that Airbus maintains control over its own supply chain and prevents Boeing from gaining undue influence over its competitor's production.

Meanwhile, the vice president leading Boeing's Starliner spacecraft unit "has left his role in the program and been replaced by the company's International Space Station program manager, John Mulholland," Reuters reports, citing a Boeing spokesperson. In its first test mission last summer flying astronauts, Starliner was forced by NASA to leave its crew aboard the ISS and return empty in September over problems with its propulsion system. A panel of senior NASA officials in August had voted to have a Crew Dragon capsule from Elon Musk's SpaceX bring them back instead, deeming Starliner too risky for the astronauts.

Paul Hill, a veteran NASA flight director and member of the agency's Aerospace Safety Advisory Panel, said during a quarterly panel meeting on Thursday that NASA and Boeing continue to investigate Starliner's propulsion system. A Boeing spokesperson said on Thursday that the company and NASA have not yet determined what Starliner's next mission will look like, such as whether it will need to repeat its crewed flight test before receiving NASA certification for routine flights.

Could Earthquake Sensors Help Detect Falling Space Junk? (msn.com) 18

An anonymous reader shared this report from the Washington Post: Scientists have found that using seismometers is a new and inexpensive method to detect falling space junk, which can cause damage on impact and carry toxic materials — and may someday turn deadly...

It's not an easy task to track large hunks of falling metal everywhere in the world. Ground-based radar can detect falling objects, but it doesn't cover much of the world or is often classified data, said Ben Fernando [a planetary scientist at Johns Hopkins University who is leading this research]. The other option is through optical instruments, such as doorbell cameras, but the information on the time, size and speed can be limited. Instead, Fernando turned to seismology data. Stations located around the world live-stream data, which can be easily downloaded. Seismometers have been used to track meteors in the sky for over a century, but he said this is the first time he's aware of its use for tracking space debris.

Stations located around the world live-stream data, which can be easily downloaded. Seismometers have been used to track meteors in the sky for over a century, but he said this is the first time he's aware of its use for tracking space debris. Fernando first tested the idea to track the controlled reentry of NASA's OSIRIS-REx mission in September 2023, which brought back material from the asteroid Bennu. He set up seismometers along the capsule's path in the landing spot in Utah and measured its sonic boom. "It's a really good way of monitoring what's coming in, how often it's coming in, how big the things hitting the Earth are," said Fernando, who presented his results at the American Geophysical Union conference in December...

"The shockwave deforms the ground around the seismometer," said Fernando. "It also keeps ringing for a lot longer because all of that energy is bouncing around in the soil...." [H]e said an automated system could help detect these objects within moments of it appearing on the stations. In addition to detecting an event, the seismometers can help locate where any debris may have fallen. Tracking debris is important because some space debris can contain toxic materials that can harm the surrounding environment.

The article notes reports of the uncontrolled reentry into Earth's atmosphere of at least 951 objects larger than one square meter from 2010 to 2022.

"On average, objects heavier than 1,000 pounds came down about every 8 days... In fact, the threat of getting hit by uncontrolled orbital reentries has increased by a factor of four from 2010 to 2023, said Luciano Anselmo, who published a study assessing the risk."

Slashdot Asks: Do You Remember Your High School's 'Computer Room'? (gatesnotes.com) 192

Bill Gates' blog has been updated with short videos about his upcoming book, including one about how his school ended up with an ASR-33 teletype that could connect their Seattle classroom to a computer in California. "The teachers faded away pretty quickly," Gates adds, "But about six of us stayed hardcore. One was Paul Allen..." — the future co-founder of Microsoft. And the experience clearly meant a lot to Gates. "Microsoft just never would've happened without Paul — and this teletype room."

In a longer post thanking his "brilliant" teachers, Gates calls his teletype experience "an encounter that would shape my entire future" and "opened up a whole new world for me." Gates also thanks World War II Navy pilot and Boeing engineer Bill Dougall, who "was instrumental in bringing computer access to our school, something he and other faculty members pushed for after taking a summer computer class... The fascinating thing about Mr. Dougall was that he didn't actually know much about programming; he exhausted his knowledge within a week. But he had the vision to know it was important and the trust to let us students figure it out."

Gates shared a similar memory about the computer-room's 20-something overseer Fred Wright, who "intuitively understood that the best way to get students to learn was to let us explore on our own terms. There was no sign-up sheet, no locked door, no formal instruction." Instead, Mr. Wright let us figure things out ourselves and trusted that, without his guidance, we'd have to get creative... Some of the other teachers argued for tighter regulations, worried about what we might be doing in there unsupervised. But even though Mr. Wright occasionally popped in to break up a squabble or listen as someone explained their latest program, for the most part he defended our autonomy...

Mr. Wright gave us something invaluable: the space to discover our own potential.

Most Men Would Marry Their AI Girlfriends If It Were Legal (vice.com) 152

An anonymous reader quotes a report from VICE News: EVA AI, a platform allowing you to create and connect with your own AI partner, recently surveyed 2,000 men and found that 8 in 10 would consider marrying an AI girlfriend if it were legal. Not only that, but 83% of men also believe they could form a deep emotional bond with an AI girlfriend. What's even scarier is that a whopping 78% of men surveyed said they would consider creating a replica of their ex, and three-quarters would duplicate their current partner to create a "polished" version of them. "AI companionship allows people to be their authentic selves without fear of judgment," said Cale Jones, head of community growth at EVA AI. "It creates a safe space to explore thoughts, emotions, and desires that might feel too vulnerable to share in real life. The benefits extend far beyond the virtual world: one EVA AI user discovered her bisexuality through this platform -- something she previously felt too insecure to explore in real life."

Quantum Computer Built On Server Racks Paves the Way To Bigger Machines (technologyreview.com) 27

An anonymous reader quotes a report from MIT Technology Review: A Canadian startup called Xanadu has built a new quantum computer it says can be easily scaled up to achieve the computational power needed to tackle scientific challenges ranging from drug discovery to more energy-efficient machine learning. Aurora is a "photonic" quantum computer, which means it crunches numbers using photonic qubits -- information encoded in light. In practice, this means combining and recombining laser beams on multiple chips using lenses, fibers, and other optics according to an algorithm. Xanadu's computer is designed in such a way that the answer to an algorithm it executes corresponds to the final number of photons in each laser beam. This approach differs from one used by Google and IBM, which involves encoding information in properties of superconducting circuits.

Aurora has a modular design that consists of four similar units, each installed in a standard server rack that is slightly taller and wider than the average human. To make a useful quantum computer, "you copy and paste a thousand of these things and network them together," says Christian Weedbrook, the CEO and founder of the company. Ultimately, Xanadu envisions a quantum computer as a specialized data center, consisting of rows upon rows of these servers. This contrasts with the industry's earlier conception of a specialized chip within a supercomputer, much like a GPU. [...]

Xanadu's 12 qubits may seem like a paltry number next to IBM's 1,121, but Tiwari says this doesn't mean that quantum computers based on photonics are running behind. In his opinion, the number of qubits reflects the amount of investment more than it does the technology's promise. [...] Xanadu's next goal is to improve the quality of the photons in the computer, which will ease the error correction requirements. "When you send lasers through a medium, whether it's free space, chips, or fiber optics, not all the information makes it from the start to the finish," he says. "So you're actually losing light and therefore losing information." The company is working to reduce this loss, which means fewer errors in the first place. Xanadu aims to build a quantum data center, with thousands of servers containing a million qubits, in 2029.
The company published its work on chip design optimization and fabrication in the journal Nature.

Asteroid Contains Building Blocks of Life, Say Scientists (bbc.com) 53

Mr. Dollar Ton shares a report from the BBC: The chemical building blocks of life have been found, among many other complex chemical compounds, in the grainy dust of an asteroid called Bennu, an analysis reveals. Samples of the space rock, which were scooped up by a Nasa spacecraft and brought to Earth, contain a rich array of minerals and thousands of organic compounds. These include amino acids, which are the molecules that make up proteins, as well as nucleobases -- the fundamental components of DNA. The findings are published in two papers in the journal nature.

Astronomers Discover 196-Foot Asteroid With 1-In-83 Chance of Hitting Earth In 2032 84

Astronomers have discovered a newly identified asteroid that has a 1-in-83 chance of striking Earth on December 22, 2032, though the most likely scenario is a close miss. Designated as 2024 YR4, the asteroid measures in at 196 feet wide and is currently 27 million miles away. Space.com reports: The near-Earth object (NEO) discovered in 2024, which is around half as wide as a football field is long, will make a very close approach to Earth on Dec. 22, 2032. It's estimated to come within around 66,000 miles (106,200 kilometers) of Earth on that day, according to NASA's Center of NEO Studies (CNEOS). However, when orbital uncertainties are considered, that close approach could turn out to be a direct hit on our planet.

Such an impact could cause an explosion in the atmosphere, called an "airburst," or could cause an impact crater when it slams into the ground. This is enough to see asteroid 2024 YR4 leap to the top of the European Space Agency's NEO impact Risk List and NASA's Sentry Risk Table.
"People should absolutely not worry about this yet," said Catalina Sky Survey engineer and asteroid hunter David Rankin. "Impact probability is still very low, and the most likely outcome will be a close approaching rock that misses us."

As for where it could hit Earth, Rankin said that the "risk corridor" for impact runs from South America across the Atlantic to sub-Saharan Africa.

Boom Supersonic XB-1 Breaks Sound Barrier During Historic Test Flight (cbsnews.com) 65

The XB-1, a civilian supersonic jet developed by Boom Supersonic, successfully broke the sound barrier during a test flight over the Mojave Desert. It reached an altitude of 35,290 feet before accelerating to Mach 1.22, the company said in a press release. CBS News reports: It marks the first time an independently developed jet has broken the sound barrier, Boom Supersonic said, and the plane is the "first supersonic jet made in America." The sound barrier was broken for the first time in 1947, when Air Force pilot Capt. Chuck Yeager flew a rocket-propelled experimental aircraft across the Mojave Desert -- taking off from the Mojave Air and Space Port just as the XB-1 did. [...]

The company will next focus its attention on Overture, a supersonic airliner that will ultimately "bring the benefits of supersonic flight to everyone," Boom Supersonic founder and CEO Blake Scholl said in a statement. The XB-1 jet will be the foundation for Overture, Boom Supersonic said, and many features present on the jet will also be incorporated into the supersonic airliner. The airliner will also use Boom Supersonic's bespoke propulsion system, Symphony, to run on "up to 100% sustainable aviation fuel."

The company said the goal for the plane is for it to be able to carry between 64 and 80 passengers at Mach 1.7, or about 1,295 miles per hour. Existing subsonic airliners fly at between 550 and 600 miles per hour, according to charter company Bitlux. About 130 Overture planes have been pre-ordered, the company said. Airlines including American Airlines, United Airlines and Japan Airlines have placed pre-orders. The company finished building a "superfactory" in North Carolina in 2024, and will eventually produce 66 planes per year.

Report of Newly-Discovered Asteroid Turns Out to Be... a Tesla Roadster (usatoday.com) 99

Founded in 1947, the Minor Planet Center is the official worldwide authority "for observing and reporting new asteroids, comets and other small bodies in the solar system," reports USA Today.

Unfortunately, "What an amateur astronomer recently took to be a newly discovered asteroid turned out to be a Tesla Roadster," The Minor Planet Center didn't initially consider the possibility when the organization announced the discovery on Jan. 2 of the unusual asteroid, complete with an official name: 2018 CN41. But less than 17 hours later, the Minor Planet Center issued an editorial notice that it would be deleting 2018 CN41 from its records... According to the Minor Planet Center's notice regarding the deletion, turns out the object was the Roadster, along with the Falcon Heavy rocket's upper stage.

AI Mistakes Are Very Different from Human Mistakes (schneier.com) 114

Bruce Schneier and Nathan E. Sanders, writing in a post: Someone who makes calculus mistakes is also likely to respond "I don't know" to calculus-related questions. To the extent that AI systems make these human-like mistakes, we can bring all of our mistake-correcting systems to bear on their output. But the current crop of AI models -- particularly LLMs -- make mistakes differently.

AI errors come at seemingly random times, without any clustering around particular topics. LLM mistakes tend to be more evenly distributed through the knowledge space. A model might be equally likely to make a mistake on a calculus question as it is to propose that cabbages eat goats. And AI mistakes aren't accompanied by ignorance. A LLM will be just as confident when saying something completely wrong -- and obviously so, to a human -- as it will be when saying something true. The seemingly random inconsistency of LLMs makes it hard to trust their reasoning in complex, multi-step problems. If you want to use an AI model to help with a business problem, it's not enough to see that it understands what factors make a product profitable; you need to be sure it won't forget what money is.

[...] Humans may occasionally make seemingly random, incomprehensible, and inconsistent mistakes, but such occurrences are rare and often indicative of more serious problems. We also tend not to put people exhibiting these behaviors in decision-making positions. Likewise, we should confine AI decision-making systems to applications that suit their actual abilities -- while keeping the potential ramifications of their mistakes firmly in mind.

Scientists Detect Chirping Cosmic Waves In an Unexpected Part of Space (apnews.com) 14

Scientists have detected cosmic "chorus waves" resembling bird chirps over 62,000 miles from Earth, a region where such waves have never been observed. "Scientists still aren't sure how the perturbations happen, but they think Earth's magnetic field may have something to do with it," reports the Associated Press. From the report: The chorus has been picked up on radio antennas for decades, including receivers at an Antarctica research station in the 1960s. And twin spacecraft -- NASA's Van Allen Probes -- heard the chirps from Earth's radiation belts at a closer distance than the newest detection. The latest notes were picked up by NASA's Magnetospheric Multiscale satellites, launched in 2015 to explore the Earth and sun's magnetic fields. The new research was published Wednesday in the journal Nature.

Chorus waves have also been spotted near other planets including Jupiter and Saturn. They can even produce high-energy electrons capable of scrambling satellite communications. "They are one of the strongest and most significant waves in space," said study author Chengming Liu from Beihang University in an email. The newfound chorus waves were detected in a region where Earth's magnetic field is stretched out, which scientists didn't expect. That raises fresh questions about how these chirping waves form. "It's very captivating, very compelling," Jaynes said. "We definitely need to find more of these events."
