Kenneth Stephen (Slashdot reader #1,950) writes: As the world rolls back on using coal to extract energy, it leaves behind empty coal mines. The BBC reports that the UK is actively using these coal mines as a source of geothermal energy.
The BBC visits a wine warehouse in the northeast England town Gateshead, where old coal mines "could still have a role to play in heating homes — but this time, without burning fossil fuels." A new district heating system in Gateshead is poised to begin warming homes and buildings in the area at a cost 5% below market rate, using the clean heat from its mines 150m (490ft) below the ground.
The water in the mines is naturally heated in the surrounding rocks to 20 degrees C (68 degrees Fahrenheit), according to the video report — so a heat exchanger on the surface just repurposes the extracted heat for energy consumers. It's a technique that's also being adopted in the Netherlands. But it's especially applicable in the U.K., where a quarter of homes are above old coal fields (as are 9 of its 10 major urban centers).

The report points out that coal is the world's largest source of CO2 emissions, but now coal production in the UK has fallen by 94% in the last 10 years. "So what happens when the coal mines that used to power our cities are no longer used?"

The search for life beyond Earth "follows the water," reports the Economist (since water is vital for earth's lifeforms, and the laws of chemistry are universal). "For most of the space age that insight led scientists to Mars." But... More and more, though, planetary scientists are following the water to other places — and in particular to the so-called "icy moons" that orbit Jupiter, Saturn, Neptune and Uranus, the solar system's quartet of giant gas planets. Many of those moons are either known or suspected to have oceans beneath their icy shells, kept liquid by gravitational squeezing from the planets they orbit.

On April 13th, if all goes well, a new spacecraft will blast off from French Guiana en route to Jupiter with the aim of investigating some of those watery moons up close. The European Space Agency's Jupiter Icy Moons Explorer (given the slightly contrived acronym "JUICE ") will slingshot once around Venus and three times around Earth before arriving at Jupiter in 2031.... JUICE will investigate three of the so-called Galilean moons — Callisto, Europa and Ganymede, all of which are thought to have subsurface oceans. (The fourth, Io, is arid, and so not of interest.)

Ganymede is the probe's primary target. Despite being a moon, it is bigger than the planet Mercury. Its subsurface ocean may contain more water than all of Earth's oceans combined. The probe's cameras will add much more detail to the existing, low-resolution maps of Ganymede's surface. An ice-penetrating radar will scan several kilometres below the ground. A magnetometer will take advantage of the fact that Ganymede, apparently uniquely among the solar system's moons, has a weak magnetic field that interacts with the much bigger field generated by Jupiter itself. The subtleties of that magnetic field were an early clue for the existence of an ocean, hinting at the presence of a large chunk of conductive fluid — such as salty water — beneath the surface. Better readings of the magnetic field will help scientists estimate just how big the ocean is....

Nor is JUICE the only probe on its way to Jupiter. Next year NASA will launch Europa Clipper, focused, as its name suggests, on Europa. Despite its later launch, it will take a quicker route to Jupiter, arriving a few months before JUICE . And, because there are limits to what can be discerned from orbit, both NASA and the Europeans are sketching plans for future landers that would descend to the surface of such moons to sample the seawater directly.

"As automakers scour the planet for the metals it will take to build tens of millions of electric cars, they are deliberately taking a detour around one of the only places on earth where so much of what they need is laying around and available to be plucked," reports the Washington Post: The deep seabed is teeming with potato-sized rocks packed with the nickel, cobalt, copper and manganese EV manufacturers covet. But efforts by mining companies to harvest the nodules with undersea robots are hitting rough waters. EV manufacturers who need the minerals for their batteries are distancing themselves from the practice as diplomats and scientists sound an alarm over the ecological damage that could be caused by rushing to scrape the sea floor.

The misgivings of the auto companies are hardly assuaged by the messy, contentious deliberations over it all at the headquarters of the United Nations-chartered International Seabed Authority here. The authority, tasked with protecting and guiding development in international waters, has been in turmoil since the small Pacific Island nation of Nauru invoked a clause tucked in the Law of the Sea that could allow mining within months, likely before the full environmental impact is known or regulations are put in place....

More than 700 marine scientists have signed a petition demanding a [mining] moratorium, which is also supported by 13 countries. French President Emmanuel Macron is calling for a permanent ban.... Some car manufacturers, including BMW, Renault, Rivian, Volvo and VW publicly support a moratorium on seabed mining. GM, Ford and Daimler are, for now, keeping deep seabed materials out of their supply chain plans amid corporate concerns about environmental impact.
The Post got an interesting perspective from Ethan Elkind, director of the climate program at UC Berkeley's Center for Law, Energy and the Environment. "Auto companies don't want EV batteries associated with more destruction than they already have been," he tells them. "If ecological damage of these sensitive undersea areas comes to light after mining begins, they don't want to be a part of it."

Long-time Slashdot reader schwit1 shared this report from NBC News: The Chinese spy balloon that flew across the U.S. was able to gather intelligence from several sensitive American military sites, despite the Biden administration's efforts to block it from doing so, according to two current senior U.S. officials and one former senior administration official. China was able to control the balloon so it could make multiple passes over some of the sites (at times flying figure-eight formations) and transmit the information it collected back to Beijing in real time, the three officials said.

The intelligence China collected was mostly from electronic signals, which can be picked up from weapons systems or include communications from base personnel, rather than images, the officials said. The three officials said China could have gathered much more intelligence from sensitive sites if not for the administration's efforts to move around potential targets and obscure the balloon's ability to pick up their electronic signals by stopping them from broadcasting or emitting signals.
America's Department of Defense "directed NBC News to comments senior officials made in February that the balloon had 'limited additive value' for intelligence collection by the Chinese government 'over and above what [China] is likely able to collect through things like satellites in low earth orbit.'"

A NASA instrument to provide unprecedented resolution of monitoring major air pollutants -- down to four square miles -- lifted off on its way to geostationary orbit at 12:30 a.m. EDT Friday. The Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument will improve life on Earth by revolutionizing the way scientists observe air quality from space. From a report: "The TEMPO mission is about more than just studying pollution -- it's about improving life on Earth for all. By monitoring the effects of everything from rush-hour traffic to pollution from forest fires and volcanoes, NASA data will help improve air quality across North America and protect our planet," said NASA Administrator Bill Nelson. [...] From a fixed geostationary orbit above the equator, TEMPO will be the first space-based instrument to measure air quality over North America hourly during the daytime and at spatial regions of several square miles -- far better than existing limits of about 100 square miles in the U.S. TEMPO data will play an important role in the scientific analysis of pollution, including studies of rush hour pollution, the potential for improved air quality alerts, the effects of lightning on ozone, the movement of pollution from forest fires and volcanoes, and even the effects of fertilizer application.

TEMPO's observations will dramatically improve the scientific data record on air pollution -- including ozone, nitrogen oxide, sulfur dioxide and formaldehyde -- not only over the continental United States, but also Canada, Mexico, Cuba, the Bahamas, and part of the island of Hispaniola. "Our TEMPO slogan is 'It's about time,' which hints at TEMPO's ability to provide hourly air pollution data," said Xiong Liu, deputy principal investigator for TEMPO at the Center for Astrophysics, Harvard & Smithsonian in Cambridge, Massachusetts. "After working on the TEMPO for more than 10 years, it is about time to launch TEMPO to produce real TEMPO data and start the new era of air quality monitoring over North America."

The world needs a "business mindset" to tackle the climate crisis, the president of the next UN climate summit has said. From a report: Sultan Al Jaber, the president-designate of the Cop28 summit to be hosted in the United Arab Emirates later this year, said he aimed to use the UN talks to set out how the private sector can limit greenhouse gas emissions and give businesses and governments a clear set of tasks and targets. "We need a major course correction and a massive effort to reignite progress. This cannot be done by governments alone," Al Jaber told the Guardian in a rare interview, his first with a global newspaper since taking on the Cop28 role.

"The scale of the problem requires everyone working in solidarity. We need partnerships, not polarisation, and we need to approach this with a clear-eyed rationale and executable plan of action," he said. "Cop28 is committed to building on the progress made at Cop26 and Cop27 to inject a business mindset, concrete KPIs [key performance indicators, a cornerstone of most commercial strategies] and an ambitious action-oriented agenda." Al Jaber, as well as being the UAE minister for industry and advanced technology, is better known as a businessman, chief executive of the UAE national oil company, Adnoc, one of the world's biggest oil and gas producers, and the founding chief executive of its renewable energy company Masdar.

An anonymous reader quotes a report from the Guardian: Record temperatures, devastating floods and superstorms are causing death and destruction across the planet but humans are failing to cut greenhouse gas emissions fueling the climate emergency, new US data shows. Atmospheric levels of carbon dioxide (CO2), methane and nitrous oxide -- the greenhouse gases emitted by human activity that are the most significant contributors to global heating -- continued to increase rapidly during 2022, according to the National Oceanic and Atmospheric Administration (Noaa).

Carbon dioxide levels rose by more than two parts per million (ppm) for the 11th consecutive year: the highest sustained rate of CO2 increases since monitoring began 65 years ago. Before 2013, scientists had never recorded three consecutive years of such high CO2 growth. Atmospheric CO2 is now 50% higher than pre-industrial levels. The 2022 methane rise was the fourth-largest since records began in 1983, following record growth in 2021 and 2022, and now stands at an average of 1,912 parts per billion (ppb). Methane is a potent greenhouse gas less abundant than CO2 but which warms the Earth's atmosphere much faster, and today is responsible for about 25% of the heat trapped by all greenhouse gases. "Methane levels in the atmosphere are now more than two and a half times their pre-industrial level," adds the Guardian. "The oil and gas sector is the largest industrial source of methane, which can also cause medical complications, fires and even engine failure leading helicopters to fall out of the sky."

"Levels of nitrous oxide, the third-most significant anthropogenic greenhouse gas, are now 24% higher than preâ"industrial levels, following a 1.25ppb rise last year." While fossil fuel-powered vehicles are a major source of nitrous oxide, the primary culprits behind the rising levels have been synthetic fertilizers and livestock manure from industrialized agriculture, says the report.

China is considering banning the export of technologies used to produce high-performance rare earth magnets deployed in electric vehicles, wind turbine motors and other products, citing "national security" as a reason, it has been learned. From a report: With the global trend toward decarbonization driving a shift toward the use of electric motors, China is believed to be seeking to seize control of the magnet supply chain and establish dominance in the burgeoning environment sector.

Beijing is currently in the process of revising its Catalogue of Technologies Prohibited and Restricted from Export -- a list of manufacturing and other industrial technologies subject to export controls -- and released a draft of the revised catalog for public comment in December. In the draft, manufacturing technologies for high-performance magnets using such rare earth elements as neodymium and samarium cobalt were added to the export ban. The solicitation of comments ceased late January and the revisions are expected to be adopted as early as this year.

Antarctica's melting ice sheet could retreat much faster than previously thought, new research suggests. The BBC reports: The evidence comes from markings on the seafloor off Norway that record the pull-back of a melting European ice sheet thousands of years ago. Today, the fastest withdrawing glaciers in Antarctica are seen to retreat by up to 30m a day. But if they sped up, the extra melt water would have big implications for sea-level rises around the globe. Ice losses from Antarctica caused by climate change have already pushed up the surface of the world's oceans by nearly 1cm since the 1990s. The researchers found that with the Norwegian sheet, the maximum retreat was more than 600m a day.

"This is something we could see if we continue with the upper estimates for temperature rise," explained Dr Christine Batchelor from Newcastle University, UK. "Although, worryingly, when we did the equations to think about what would be needed to instigate such retreat in Antarctica, we actually found there are places where you could get similar pulses of withdrawal even under the basal melt rates we know are happening at the moment," she told BBC News. The findings have been published in the journal Nature.

Chemicals that were banned after they punched a hole in Earth's ozone layer are still building up at an alarming rate in our atmosphere, according to research published today in the journal Nature Geoscience. The chemicals were once widely used in air conditioning and refrigeration but were supposed to be phased out globally by 2010. From a report: Scientists were surprised to find that concentrations of several types of those chemicals have climbed since then, reaching a record high in 2020. The culprit could be alternative refrigerants that were meant to replace the ozone-depleting substances, the new research suggests. An even bigger problem? Researchers can't find where all the chemicals are leaking from. The ozone layer has managed to make a remarkable recovery over the past few decades. If emissions continue to climb, however, it could counteract some of that progress and exacerbate climate change.

Cruising at a depth of 8,336 meters (over 27,000 feet) just above the seabed, a young snailfish has become the deepest fish ever filmed by scientists during a probe into the abyss of the northern Pacific Ocean. From a report: Scientists from University of Western Australia and Tokyo University of Marine Science and Technology released footage of the snailfish on Sunday filmed last September by sea robots in deep trenches off Japan. Along with the filming the deepest snailfish, the scientists physically caught two other specimens at 8,022 meters and set another record for the deepest catch. Previously, the deepest snailfish ever spotted was at 7,703 meters in 2008, while scientists had never been able to collect fish from anywhere below 8,000 meters. "What is significant is that it shows how far a particular type of fish will descend in the ocean," said marine biologist Alan Jamieson, founder of the Minderoo-UWA Deep Sea Research Centre, who led the expedition. Scientists are filming in the trenches off Japan as part of a 10-year study into the deepest fish populations in the world. Snailfish are members of Liparidae family, and while most snailfish live in shallow water, others survive at some of the greatest depths ever recorded, Jamieson said.

A Canadian astronaut and three NASA veterans, including one of the world's most experienced female spacewalkers, will fly around the moon next year in the first piloted voyage beyond Earth orbit since the Apollo program ended 50 years ago, the space agency announced Monday. From a report: NASA's Reid Wiseman, Christina Koch and Victor Glover will join Canadian rookie Jeremy Hansen aboard an Orion crew capsule for the Artemis program's second fight, the first carrying a crew bound for the moon. The Artemis 2 mission is intended to pave the way toward the first moon landing -- Artemis 3 -- in the 2025-26 timeframe. Wiseman, Koch and Glover are all veterans of long-duration stays aboard the International Space Station while Hansen will be making his first space flight. Navy Capt. Wiseman, 47, a widowed father of two, is a veteran F/A-18F Super Hornet pilot who holds a master's in systems engineering. He launched aboard a Russian Soyuz spacecraft in 2014 and spent 165 days aboard the space station, then served as chief astronaut after his return to Earth.

Koch, 44, holds a master's in electrical engineering who has experience in Antarctic research. She also launched aboard a Soyuz and spent nearly a full year aboard the lab in 2019-20, venturing outside for six spacewalks, including three all-female excursions. With 42 hours and 15 minutes of EVA time, she ranks third on the list of most experienced female spacewalkers. Glover, 46, is a Navy captain, a father of four and one of only a half dozen African Americans in NASA's astronaut corps. He launched to the station aboard the first operational SpaceX Crew Dragon mission in 2021-22, logging 168 days in orbit. Glover is a veteran test pilot with more than 3,000 hours of flight time and more than 400 carrier landings. Hansen, a 47-year-old colonel in the Canadian armed forces and father of three, is a veteran F-18 fighter pilot. He will be the ninth Canadian to fly in space and the first to venture beyond Earth orbit.

Remember that entrepreneur planning an ostentatious NFT-based restaurant/members-only club in San Francisco? Seven months later it's still "an empty husk of a building, hindered by construction delays and unfulfilled crypto dreams," reports SFGate: Last August, Joshua Sigel held a "groundbreaking" event at what he said would be the future home of Sho Restaurant, located atop Salesforce Park in San Francisco. He told the gathered media that construction of the proposed Japanese fine dining restaurant would begin in less than two months, once some permitting issues were resolved, with a targeted opening date of September or October of 2023.

Sigel maintained that he'd soon be offering 3,275 Sho Club NFT (non-fungible token) memberships — first via a private sale, then a larger public sale in late September — which would serve as the backbone of Sho Restaurant's clientele. (Sigel is the CEO of Sho Group, which encapsulates Sho Restaurant and Sho Club.) There were to be 2,878 "Earth" NFT memberships, priced at $7,500 each; 377 "Water" NFT memberships, priced at $15,000 each; and 20 "Fire" NFT memberships; priced at $300,000 each. The NFTs are basically membership cards for the restaurant, spruced up with Web3 jargon.... Each membership tier comes with increasingly luxurious benefits, though restaurant reservations would also be available for nonmembers.

Seven months later, things don't seem to be going very well for Sho Club or for Sho Restaurant. I recently walked over to Salesforce Park and peered inside the shell of the building that's supposed to become a restaurant; I saw an empty space that looks almost exactly the same as it did in August. The mock-up design photos that journalists looked at during the "groundbreaking" in August remain strewn about on the floor. Permits for Sho Restaurant haven't been issued, the result of Sho Restaurant designers not yet responding to a number of San Francisco Department of Building Inspection notes, among a host of permitting steps that haven't been completed. Sho Club social media accounts have been radio silent since late September....

Sho Club appears to have sold around 100 NFT memberships, rather than 3,275, as Sigel originally projected. I repeatedly reached out to Sigel, to Sho Club, and its public relations representatives. No one replied to my questions.

America's Department of Defense "is gearing up for a future conflict in space," reports the Wall Street Journal, "as China and Russia deploy missiles and lasers that can take out satellites and disrupt military and civilian communications." The White House this month proposed a $30 billion annual budget for the U.S. Space Force, almost $4 billion more than last year and a bigger jump than for other services including the Air Force and the Navy.... A key aim of a stand-alone force was to plan, equip and defend U.S. interests in space for all of the services and focus attention on the emerging threats. For the first time, the spending request also includes plans for simulators and other equipment to train Guardians, as Space Force members are known, for potential battle....

Just as it is on Earth, China is the Pentagon's big worry in space. In unveiling a defense strategy late last year, the Biden administration cast China as the greatest danger to U.S. security. In space, the threats from China range from ground-launched missiles or lasers that could destroy or disable U.S. satellites, to jamming and other cyber interference and attacks in space, said Pentagon officials. China has invested heavily in its space program, with a crewed orbiting station, developing ground-based missiles and lasers as well as more surveillance capabilities. This is part of its broader military aims of denying adversaries access to space-based assets.

China is "testing on-orbit satellite systems which could be weaponized as they have already shown the capability to physically control and move other satellites," Gen. Chance Saltzman, chief of space operations for the U.S. Space Force, told a congressional hearing this month. "There's nothing we can do in space that's of any value if the networks that process the information and data are vulnerable to attack," Gen. Saltzman said. A central part of the Space Force's next tranche of military contracts for rocket launches is protecting them from attacks by China and other adversaries. The hope is to make satellites tougher to approach by adversaries' equipment as well as less susceptible to lasers and jamming from space or the ground, said Space Force leaders.
The article also notes the US Defense Department "is moving away from a small number of school bus-size satellites to a planned constellation of hundreds of smaller ones.

"The larger number of targets makes any one satellite less crucial to the network but also requires changes in the capabilities of the satellites themselves, the rockets that put them into orbit and the communications systems they host."

Today a warning was published from the editorial board of the San Francisco Chronicle. "Experts say post-pandemic woes stemming from office workers staying home instead of commuting into the city could send San Francisco into a 'doom loop' that would gut its tax base, decimate fare-reliant regional transit systems like BART and trap it in an economic death spiral...." Despite our housing crisis, it was years into the COVID pandemic before our leaders meaningfully questioned the logic of reserving some of the most prized real estate on Earth for fickle suburbanites and their cars. Downtown, after all, was San Francisco's golden goose. Companies in downtown offices accounted for 70% of San Francisco's pre-pandemic jobs and generated nearly 80% of its economic output, according to city economist Ted Egan. And so we wasted generous federal COVID emergency funds trying to bludgeon, cajole and pray for office workers to return downtown instead of planning for change. We're now staring down the consequences for that lack of vision.

The San Francisco metropolitan area's economic recovery from the pandemic ranked 24th out of the 25 largest regions in the U.S., besting only Baltimore, according to a report from the Bay Area Council Economic Institute. In the first quarter of 2023, San Francisco's office vacancy rate shot up to a record-high 29.4% — the biggest three-year increase of any U.S. city. The trend isn't likely to end anytime soon: In January, nearly 30% of San Francisco job openings were for hybrid or fully remote work, the highest share of the nation's 50 largest cities. Amid lower property, business and real estate transfer taxes, the city is projecting a $728 million deficit over the next two fiscal years. Transit ridership remains far below pre-pandemic levels. In January, downtown San Francisco BART stations had just 30% of the rider exits they did in 2019, according to a report from Egan's office. Many Bay Area transit agencies, including Muni, are rapidly approaching a fiscal cliff.

San Francisco isn't dead; as of March, it was home to an estimated 173 of the country's 655 companies valued at more than $1 billion. Tourism is beginning to rebound. And new census data shows that San Francisco's population loss is slowing, a sign its pandemic exodus may be coming to an end. But the city can't afford to wait idly for things to reach equilibrium again. It needs to evolve — quickly. Especially downtown. That means rebuilding the neighborhood's fabric, which won't be cheap or easy. Office-to-housing conversions are notoriously tricky and expensive. Demolishing non-historic commercial buildings that no longer serve a purpose in the post-pandemic world is all but banned. And, unlike New York after 9/11, San Francisco is a city that can't seem to stop getting in its own way.
So what's the solution? The CEO of the Bay Area Council suggests public-private partnerships that "could help shift downtown San Francisco's focus from tech — with employees now accustomed to working from home — to research and development, biotech, medical research and manufacturing, which all require in-person workers."

And last week San Francisco's mayor proposed more than 100 changes to streamline the permitting process for small businesses, and on Monday helped introduce legislation making it easier to convert office buildings to housing, expand pop-up business opportunities, and fill some empty storefronts. This follows a February executive order to speed housing construction. The editorial points out that "About 40% of office buildings in downtown San Francisco evaluated in a study would be good candidates for housing due to their physical characteristics and location and could be converted into approximately 11,200 units, according to research from SPUR and the Urban Land Institute San Francisco."

But without some action, the editorial's headline argues that "Downtown San Francisco is at risk of collapsing — and taking much of the Bay Area with it."

It was 10 times brighter than any previously detected, reports the BBC, noting it illuminated much of the galaxy.

RockDoctor (Slashdot reader #15,477) writes: A recent paper on ArXiv describes a Gamma Ray Burst (GRB) whose light arrived late last year as one of the strongest ever observed. GRB 221009A was detected on October 9 last year (yes, that number is a date), so 5 and a bit months from event to papers published is remarkably quick, and I anticipate that there will be a lot more papers on it in the future. Stand-out points are :


- it lasted for more than ten hours after detection (a space x-ray telescope had time to orbit out of the Earth's shadow and observe it)
- it could (briefly) be observed by amateur astronomers.
- it is also one of the closest gamma-ray bursts seen and is among the most energetic and luminous bursts.


It's redshift is given as z= 0.151, which Wikipedia translates as occurring 1.9 billion years ago, at a distance of 2.4 billion light-years from Earth.

Observations have been made of the burst in radio telescopes (many sites, continuing), optical (1 site ; analysis of HST imaging is still in work), ultraviolet (1 space telescope), x-ray (2 space telescopes) and gamma ray (1 sapce telescope) — over a range of 1,000,000,000,000,000-fold (10^15) in wavelength. It's brightness is such that radio observatories are expected to continue to detect it for "years to come".

The model of the source is of several (3~10) Earth-masses of material ejected from (whatever, probably a compact body (neutron star or black dwarf) merger) and impacting the interstellar medium at relativistic speeds (Lorentz factor 9, velocity >99.2% of c). The absolute brightness of the burst is high (about 10^43 J) and it is made to seem brighter by being close, and also by the energy being emitted in a narrow jet ("beamed"), which we happen to be near the axis of.

General news sites are starting to notice the reports, including the hilarious acronym of "BOAT — Brightest Of All Time". Obviously, with observations having only occurred for about 50 years. we're likely to see something else as bright within the next 50 years.

The brightness of the x-rays from this GRB is such that the x-rays scattered from dust in our galaxy creates halos around the source — which are bright enough to see, and to tell us things about the dust in our galaxy (which is generally very hard to see). Those images are more photogenic than the normal imagery for GRBs — which is nothing — so you'll see them a lot.

The Fresno Bee newspaper reports that flooding in parts of California "have also ground work to a halt at several key construction sites for California's high-speed rail project." But while standing water at some locations has prevented work crews from reaching their job sites, the Central Valley director for the Cailfornia High-Speed Rail Authority said it's the prospects for a lengthy summer run of water in local irrigation canals that present a greater potential disruption to construction later this year....

At the Tule River viaduct near Highway 43 and Avenue 144 south of Corcoran, drone video posted to social media on March 22 by the Tulare County Sheriff's Office shows vehicles stranded in floodwaters and support columns for the structure sticking out of the water. "There's a lot of work we can't get to," Garth Fernandez, who heads up the rail agency's Central Valley region, told The Fresno Bee in a telephone interview this week. "So at Tule River and Deer Creek, right now we are not working. ... We don't even have access to that (Deer Creek) site right now because it's all under water." Fernandez added that in the meantime, the rail agency and its contractor have turned their attention to providing what help they can to nearby communities that are being affected by flooding....

While some construction locations are facing delays because of standing flood water, crews have been able to continue working at other sites in Madera, Fresno, Kings and Kern counties — a 119-mile stretch covered by three separate construction contracts.... So far, no significant damage has been reported on any of the high-speed rail structures that have been completed or are in various stages of construction. "From north to south, water is flowing underneath all of our completed structures," Fernandez said. "All of our structures are on piles and deep foundations, so I don't believe we'll have an issue with damage to our structures... We may have some areas of erosion, some embankments washed out in a couple of places, but that minor damage can be resolved rather easily," he added. "But for all of our major structures, the current reporting is that we are holding good."

The rail line has been designed to cope with major floods; viaducts and a railbed that will elevated above the level of the surrounding land are expected to minimize the risk of damage from future floods, Fernandez said. "Our facilities are designed for a 100-year flood, so (the current events are) showing that our design is actually working," he said. "It's designed in a way that even though it's a large system north to south, it's able to convey all the flood water past our embankments and our alignment."

"SpaceX has its first commercial cargo contract to the lunar surface," says Jaret Matthews, the founder of the tiny startup Astrolab which makes a moon rover the size of a Jeep Wrangler. The New York Times reports: On Friday, Astrolab announced that it had signed an agreement with SpaceX for its Flexible Logistics and Exploration Rover, or FLEX, to be a payload on an uncrewed Starship cargo mission that is to take off as early as mid-2026...." SpaceX, which did not respond to requests for comment, has yet to announce that it is planning this commercial Starship mission to the moon's surface, headed to the south polar region. Astrolab would be just one of the customers sharing the voluminous cargo compartment of the Starship flight, Mr. Matthews said.

Mr. Matthews, an engineer who previously worked at SpaceX and NASA's Jet Propulsion Laboratory, founded Astrolab less than four years ago. Located a stone's throw from SpaceX's headquarters in Hawthorne, Calif., it has about 20 full-time employees, he said.... Mr. Matthews declined to say how much it would cost to get FLEX to the moon or how much money Astrolab has raised. He said Astrolab would make money by lifting and deploying cargo for customers on the lunar surface. That could include scientific instruments. In the future, the rover could help build lunar infrastructure. "Essentially providing what I like to call last-mile mobility on the moon," Mr. Matthews said. "You can kind of think of it like being U.P.S. for the moon. And in this analogy, Starship is the container ship crossing the ocean, and we're the local distribution solution...."

Mr. Matthews said Astrolab already had several signed agreements for payloads. That appears to be part of the expanding potential market for [SpaceX's] Starship.... For NASA, Starship is how its astronauts will land on the moon during the Artemis III mission, currently scheduled for 2025. Before that, SpaceX is to conduct an uncrewed flight to demonstrate the capability of spacecraft to get to the moon and set down there in one piece. If those schedules hold, the commercial cargo mission with the Astrolab rover could take place the next year....

Farther into the future, the company has even grander visions. "Ultimately our goal is to have a fleet of rovers both on the moon and Mars," Mr. Matthews said. "And I really think I see these vehicles as the catalysts ultimately for the off-Earth economy."

Earlier today, more than 1,100 artificial intelligence experts, industry leaders and researchers signed a petition calling on AI developers to stop training models more powerful than OpenAI's ChatGPT-4 for at least six months. Among those who refrained from signing it was Eliezer Yudkowsky, a decision theorist from the U.S. and lead researcher at the Machine Intelligence Research Institute. He's been working on aligning Artificial General Intelligence since 2001 and is widely regarded as a founder of the field.

"This 6-month moratorium would be better than no moratorium," writes Yudkowsky in an opinion piece for Time Magazine. "I refrained from signing because I think the letter is understating the seriousness of the situation and asking for too little to solve it." Yudkowsky cranks up the rhetoric to 100, writing: "If somebody builds a too-powerful AI, under present conditions, I expect that every single member of the human species and all biological life on Earth dies shortly thereafter." Here's an excerpt from his piece: The key issue is not "human-competitive" intelligence (as the open letter puts it); it's what happens after AI gets to smarter-than-human intelligence. Key thresholds there may not be obvious, we definitely can't calculate in advance what happens when, and it currently seems imaginable that a research lab would cross critical lines without noticing. [...] It's not that you can't, in principle, survive creating something much smarter than you; it's that it would require precision and preparation and new scientific insights, and probably not having AI systems composed of giant inscrutable arrays of fractional numbers. [...]

It took more than 60 years between when the notion of Artificial Intelligence was first proposed and studied, and for us to reach today's capabilities. Solving safety of superhuman intelligence -- not perfect safety, safety in the sense of "not killing literally everyone" -- could very reasonably take at least half that long. And the thing about trying this with superhuman intelligence is that if you get that wrong on the first try, you do not get to learn from your mistakes, because you are dead. Humanity does not learn from the mistake and dust itself off and try again, as in other challenges we've overcome in our history, because we are all gone.

Trying to get anything right on the first really critical try is an extraordinary ask, in science and in engineering. We are not coming in with anything like the approach that would be required to do it successfully. If we held anything in the nascent field of Artificial General Intelligence to the lesser standards of engineering rigor that apply to a bridge meant to carry a couple of thousand cars, the entire field would be shut down tomorrow. We are not prepared. We are not on course to be prepared in any reasonable time window. There is no plan. Progress in AI capabilities is running vastly, vastly ahead of progress in AI alignment or even progress in understanding what the hell is going on inside those systems. If we actually do this, we are all going to die. You can read the full letter signed by AI leaders here.

An anonymous reader shares a report: In the midst of perpetrating what federal prosecutors say was a massive corporate hacking campaign, Israeli private detective Aviram Azari in 2017 received welcome news. A group of hackers in India wrote him to say they had successfully infiltrated the email and social-media accounts of a group of environmental activists campaigning against Exxon. "On a happy note I would like to report some success below: Project Name Rainbow," the hackers wrote in electronic messages that were viewed by The Wall Street Journal. The messages included evidence of the successful intrusions, including screenshots of compromised email inboxes.

The messages along with court records reveal new details about the hacking campaign, including that thousands of individuals and companies were targeted and at least some of the attacks resulted in the hackers successfully gaining access to the private accounts of the victims and obtaining their passwords. Among the targets was the Rockefeller Family Fund, a charity created by some of the heirs of John D. Rockefeller, who founded Exxon's forebear Standard Oil. The fund has for years been involved in campaigns arguing that Exxon hid from the public the full extent of what it knew internally about climate change and the role fossil fuels played in causing it.
