US Energy Department Announces 'Blueprint' for Slashing Emissions From Buildings and Reducing Energy Use (energy.gov) 76

This week America's Department of Energy announced "a comprehensive plan to reduce greenhouse-gas emissions from buildings by 65% by 2035 and 90% by 2050." The U.S. Department of Energy (DOE) led the Blueprint's development in collaboration with the Department of Housing and Urban Development, the Environmental Protection Agency, and other federal agencies. The Blueprint is the first sector-wide strategy for building decarbonization developed by the federal government... "America's building sector accounts for more than a third of the harmful emissions jeopardizing our air and health..." said U.S. Secretary of Energy Jennifer M. Granholm. "As part of a whole-of-government approach, the Department of Energy is outlining for the first time ever a comprehensive federal plan to reduce energy in our homes, schools, and workplaces — lowering utility bills and creating healthier communities while combating the climate crisis."

Buildings account for more than one third of domestic climate pollution and $370 billion in annual energy costs... The Blueprint projects reductions of 90% of total greenhouse gas emissions from the buildings sector, which will save consumers more than $100 billion in annual energy costs and avoid $17 billion in annual health costs.

Just for example, the Department of Energy's Affordable Home Energy Shot program "aims to reduce the upfront cost of upgrading a home by at least 50% and reduce energy bills by 20% within a decade." (Meanwhile, the federal government's role in making more change happen faster includes financing, funding R&D on lower-cost technologies, expanding markets, and "supporting the development and implementation of emissions-reducing building codes and appliance standards.")

Besides the national blueprint, the Department also announced an expansion of its Better Buildings Commercial Building Heat Pump Accelerator initiative. In this program, "manufacturers will produce higher efficiency and life cycle cost-effective heat pump rooftop units and commercial organizations will evaluate and adopt next-generation heat pump technology."

U.S. Secretary of Energy Jennifer M. Granholm said the program "builds on more than a decade of public-private partnerships to get cutting edge clean technologies from lab to market, helping to slash harmful carbon emissions throughout our economy." On average, between 20% and 30% of the nation's energy is wasted, presenting a significant opportunity to increase energy efficiency. Through the Better Buildings Initiative, DOE partners with public and private sector stakeholders to pursue ambitious portfolio-wide energy, waste, water, and/or emissions reduction goals and publicly share solutions. By improving building design, materials, equipment, and operations, energy efficiency gains can be achieved across broad segments of the nation's economy.

The Accelerator initiative was developed with commercial end users like Amazon, IKEA, and Target, and already includes manufacturers AAON, Carrier Global Corp., Lennox International, Rheem Manufacturing Co., Trane Technologies, and York International Corp. The Accelerator aims to bring more efficient, affordable next-generation heat pump rooftop units to market as soon as 2027 — which will slash both emissions and energy costs in half compared to natural gas-fueled heat pumps. If deployed at scale, they could save American businesses and commercial entities $5 billion on utility bills every year.

Wait, Does America Suddenly Have a Record Number of Bees? (spokesman.com) 77

"America's honeybee population has rocketed to an all-time high," reports the Washington Post: We've added almost 1 million bee colonies in the past five years. We now have 3.8 million, the census shows. Since 2007, the first census after alarming bee die-offs began in 2006, the honeybee has been the fastest-growing livestock segment in the country! And that doesn't count feral honeybees, which may outnumber their captive cousins several times over...

Much of the explosion of small producers came in just one state: Texas. The Lone Star State has gone from having the sixth-most bee operations in the country to being so far ahead of anyone else that it out-bees the bottom 21 states combined... [A]ll 254 Texas counties adopted bee rules requiring, for example, six hives on five acres plus another hive for every 2.5 acres beyond that to qualify for the tax break...

When the census was taken in December 2022, California had more than four times as many bees as any other state. We emailed pollination expert Brittney Goodrich at the University of California at Davis, who explained that pollinating the California almond crop "demands most of the honeybee colonies in the U.S. each year...

Sadly, however, this does not mean we've defeated colony collapse. One major citizen-science project found that beekeepers lost almost half of their colonies in the year ending in April , the second-highest loss rate on record. For now, we're making up for it with aggressive management. The Texans told us that they were splitting their hives more often, replacing queens as often as every year and churning out bee colonies faster than the mites, fungi and diseases can take them down. But this may not be good news for bees in general. "It is absolutely not a good thing for native pollinators," said Eliza Grames, an entomologist at Binghamton University, who noted that domesticated honeybees are a threat to North America's 4,000 native bees, about 40% of which are vulnerable to extinction...

Many of the same forces collapsing managed beehives also decimate their native cousins, only the natives don't usually have entire industries and governments pouring hundreds of millions of dollars into supporting them.

So while Texas bee exemptions "have become big business," the article ends with this quote from Mace Vaughan, who leads pollinator and agricultural biodiversity at Xerces, an expanding insect-conservation outfit. "The way you support both honeybees and beekeepers — and the way you save native pollinators — is to go out there and create beautiful flower-rich habitat on your farm or your garden."

How the European Space Agency Celebrated April Fool's Day (esa.int) 41

The European Space Agency has a Planetary Defence Office, which includes its Near-Earth Object Coordination Centre. "It has come to our attention," they wrote in the April edition of their monthly newsletter, "that a recent trend among journalists has been to come up with creative comparisons to convey the size of an asteroid to the public."

So then, as explained by RockDoctor (Slashdot reader #15,477) "they propose a number of standardised units of comparison for journalists describing 'death from the skies'".

An excerpt from that April 1 newsletter: In the absence of a handy skyscraper, animals commonly used have included giraffes, corgis and an entire colony of penguins. But how do these comparisons stack up? Let's look at some of our favourite unusual suspects:

- Corgi: At around 30 cm tall, a space rock the size of a corgi wouldn't pose much of a threat.

- Half a giraffe: An adult giraffe can reach up to 5.5 metres in height, so half a giraffe would be about 2.75 metres. While not as impressive as a full skyscraper, an asteroid that size could certainly destroy a building or two...

- Elephants: An adult African elephant can reach 7 metres at the shoulder. Ninety elephants stacked on top of each other would form a staggering pile over 630 metres high, creating a devastating but probably not planet-ending event.

As this menagerie of animals can cause a lot of confusion, we at the NEOCC recommend the use of a Standardised Giraffe Unit (SGU, 1 SGU = 5 penguins) for ease of comparison.

RockDoctor shares this additional thought in his original submission about the newly proposed standardized unit.

"The world may be turtles all the way down, but it's giraffes all the way up."

US Invests $20 Billion More to Finance Clean-Energy Projects (msn.com) 86

Thursday America's Environmental Protection Agency "awarded $20 billion to help finance clean-energy projects across the country," reports the Washington Post. The money comes from the Greenhouse Gas Reduction Fund established by President Biden's signature climate law, the Inflation Reduction Act. The fund seeks to leverage public and private dollars to invest in clean-energy technologies such as solar panels, heat pumps and more.

The program is potentially one of the most consequential — yet least understood — parts of the climate law...

Simply put, the program allows people to access low-interest loans for clean-energy projects that they might not otherwise have received. Imagine a community group that wants to install electric vehicle charging stations at its neighborhood recreation center but can't get a loan from a bank or a lender. As is often the case, potential lenders say they're hesitant to support a novel green technology or a business without a track record of success. Low-income and minority communities have long encountered such obstacles in trying to attract private capital. The program aims to overcome this problem by providing a huge influx of federal cash — $27 billion in total — for nonprofit organizations to dole out to clean-energy projects nationwide. Each nonprofit will serve as a "green bank" that offers more favorable lending rates than commercial banks. "It's just really hard to get banks to bring capital into low-income communities, especially for these new projects that they're not used to financing," said Adrian Deveny, the founder of the firm Climate Vision and the former director of energy and environmental policy for Senate Majority Leader Charles E. Schumer (D-N.Y.), a key architect of the Inflation Reduction Act....

The EPA is awarding money to eight nonprofits, which have committed to leverage nearly $7 in private capital for every $1 of federal investment. The nonprofits have also pledged to ensure that at least 70 percent of the funds will benefit disadvantaged communities, and that the financed projects will reduce up to 40 million metric tons of carbon dioxide a year — equivalent to the annual emissions of nearly 9 million gasoline-powered cars... [The nonprofit] Coalition for Green Capital, will use a $5 billion award to establish a "national green bank," co-founder and CEO Reed Hundt said. "We're going to be able to cause about $100 billion of total additional investment over a seven-year time period with that number, because we can leverage it," Hundt said.

NASA Figured Out Why Its Voyager 1 Probe Has Been Glitching for Months (gizmodo.com) 58

NASA engineers have traced the Voyager 1 spacecraft's transmitted gibberish to corrupted memory hardware in its flight data system (FDS). "The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn't working," NASA wrote in an update. Gizmodo reports: FDS collects data from Voyager's science instruments, as well as engineering data about the health of the spacecraft, and combines them into a single package that's transmitted to Earth through one of the probe's subsystems, the telemetry modulation unit (TMU), in binary code. FDS and TMU have been having trouble communicating with one another. As a result, TMU has been sending data to mission control in a repeating pattern of ones and zeroes. NASA's engineers aren't quite sure what corrupted the FDS memory hardware; they think that either the chip was hit by an energetic particle from space or that it's just worn out after operating for 46 years. [...] The engineers are hoping to resolve the issue by finding a way for FDS to operate normally without the corrupted memory hardware, enabling Voyager 1 to begin transmitting data about the cosmos and continue its journey through deep space.

Heat-Trapping CO2, Methane Levels In the Air Last Year Spiked To Record Highs (apnews.com) 81

According to the latest data from the U.S. National Oceanic and Atmospheric Administration, carbon dioxide and methane levels in the atmosphere reached historic highs last year, growing at near-record fast paces. The Associated Press reports: Carbon dioxide, the most important and abundant of the greenhouse gases caused by humans, rose in 2023 by the third highest amount in 65 years of record keeping, NOAA announced Friday. Scientists are also worried about the rapid rise in atmospheric levels of methane, a shorter-lived but more potent heat-trapping gas. Both jumped 5.5% over the past decade. The 2.8 parts per million increase in carbon dioxide airborne levels from January 2023 to December, wasn't as high as the jumps were in 2014 and 2015, but they were larger than every other year since 1959, when precise records started. Carbon dioxide's average level for 2023 was 419.3 parts per million, up 50% from pre-industrial times.

Last year's methane's jump of 11.1 parts per billion was lower than record annual rises from 2020 to 2022. It averaged 1922.6 parts per billion last year. It has risen 3% in just the past five years and jumped 160% from pre-industrial levels showing faster rates of increase than carbon dioxide, said Xin "Lindsay" Lan, the University of Colorado and NOAA atmospheric scientist who did the calculations. [...] The third biggest human-caused greenhouse gas, nitrous oxide, jumped 1 part per billion last year to record levels, but the increases were not as high as those in 2020 and 2021. Nitrous oxide, which lasts about a century in the atmosphere, comes from agriculture, burning of fuels, manure and industrial processes, according to the EPA.

"Studies of the specific isotopes of methane in the air show much of the increased methane is from microbes, pointing to spiking emissions from wetlands and perhaps agriculture and landfills, but not as much the energy industry, Lan said."

Mars May Not Have Had Liquid Water Long Enough For Life To Form (arstechnica.com) 53

Elizabeth Rayne reports via Ars Technica: Led by planetary researcher Lonneke Roelofs of Utrecht University in the Netherlands, a team of scientists has found that the sublimation of CO2 ice could have shaped Martian gullies, which might mean the most recent occurrence of liquid water on Mars may have been further back in time than previously thought. That could also mean the window during which life could have emerged and thrived on Mars was possibly smaller. "Sublimation of CO2 ice, under Martian atmospheric conditions, can fluidize sediment and creates morphologies similar to those observed on Mars," Roelofs and her colleagues said in a study recently published in Communications Earth & Environment. [...]

To recreate a part of the red planet's landscape in a lab, Roelofs built a flume in a special environmental chamber that simulated the atmospheric pressure of Mars. It was steep enough for material to move downward and cold enough for CO2 ice to remain stable. But the team also added warmer adjacent slopes to provide heat for sublimation, which would drive movement of debris. They experimented with both scenarios that might happen on Mars: heat coming from beneath the CO2 ice and warm material being poured on top of it. Both produced the kinds of flows that had been hypothesized. For further evidence that flows driven by sublimation would happen under certain conditions, two further experiments were conducted, one under Earth-like pressures and one without CO2 ice. No flows were produced by either. "For the first time, these experiments provide direct evidence that CO2 sublimation can fluidize, and sustain, granular flows under Martian atmospheric conditions," the researchers said in the study.

Because this experiment showed that gullies and systems like them can be shaped by sublimation and not just liquid water, it raises questions about how long Mars had a sufficient supply of liquid water on the surface for any organisms (if they existed at all) to survive. Its period of habitability might have been shorter than it was once thought to be. Does this mean nothing ever lived on Mars? Not necessarily, but Roelofs' findings could influence how we see planetary habitability in the future.

Sci-Fi

How a Micro-Budget Student Film Changed Sci-Fi Forever (bbc.com) 44

An anonymous reader writes: In the early 70s, young filmmakers John Carpenter and Dan O'Bannon created a spaceship tale for a graduation project -- little knowing it would influence Alien and many other works. Made for $60,000 by film school students, horror maestro John Carpenter's directorial debut Dark Star is now regarded as a sci-fi cult classic. Having just turned 50 years old, it's a world away from much of the sci-fi that came before it and would come after, neither space odyssey nor space opera, rather a bleak, downbeat and often absurd portrait of a group of people cooped together in a malfunctioning interstellar tin can. Arguably its most famous scene consists of an existential debate between an astronaut and a sentient bomb. Dark Star was a collaboration between Carpenter, who directed and scored the film, and Dan O'Bannon, who in addition to co-writing the script, acted as editor, production designer, and visual effects supervisor, as well as playing the volatile, paranoid Sergeant Pinback. They met as budding filmmakers at the University of Southern California. "While [Carpenter and O'Bannon] couldn't be more dissimilar in personality, they were both very energetic and focused," says Daniel Griffiths, director of Let There Be Light: The Odyssey of Dark Star (2010), the definitive documentary about the making of the film.

The sci-fi films of this period tended to be bleak and dystopian, explains John Kenneth Muir, author of The Films of John Carpenter -- films like Silent Running (1972), in which all plant life on Earth is extinct, or George Lucas's 1971 debut THX-1138, in which human emotion is suppressed. "Dark Star arrived in this world of dark, hopeless imaginings, but took the darkness one step further into absurd nihilism." Carpenter and O'Bannon set out to make the "ultimate riff on Stanley Kubrick's 2001: A Space Odyssey," says Griffiths. While Kubrick's 1968 film, explains Muir, was one "in which viewers sought meaning in the stars about the nature of humanity, there is no meaning to life in Dark Star". Rather, says Muir, it parodies 2001 "with its own sense of man's irrelevance in the scheme of things". Where Kubrick scored his film with classical music, Dark Star opens with a country song, Benson, Arizona. (A road in the real-life Benson is named in honor of the film). The film was even released with the tagline "the spaced-out odyssey." Dark Star captured the mood of the time in which it was made, says Muir, the atmosphere of Nixon's America. "The 1960s was all about utopian dreaming and bringing change to America in the counterculture. The 1970s represent what writer Johnny Byrne called 'The wake-up from the hippie dream', a reckoning with the fact that the more things change, the more they stay the same." [...]

When Dark Star premiered at the FILMEX expo in 1974, the audience response was largely positive. "They recognized the film's absurdist humor and celebrated its student film roots," says Griffiths. It had a limited theatrical release in 1975, but it was not a commercial success. "The film met with negative reviews from critics, and general disinterest from audiences," says Muir. "Both Carpenter and O'Bannon realized that all the struggles they endured to make the film did not matter to audiences, they only cared about the finished product. I think they were discouraged," says Griffiths. The growth of the VHS market, however, helped it find its audience and propelled it towards cult status. Its influence can still be felt, perhaps most directly in Ridley Scott's Alien, for which O'Bannon, who died in 2009, wrote the screenplay. The two films share DNA. Alien is also set on a grotty working vessel with a bickering crew, only this time the alien wasn't played for laughs.

Amazon Still Has a Serious Plastic Waste Problem in the US (theverge.com) 36

Despite making pledges to cut down on plastic packaging, a new report from the nonprofit conservation organization Oceana estimates that Amazon's plastic waste has continued to grow in the US. From a report: The company created 208 million pounds of plastic waste from its packaging in the US in 2022 alone, which Oceana says is enough trash to circle Earth more than 200 times in the form of plastic air pillows. That's a nearly 10 percent jump from the amount of plastic waste it generated the year before, according to the report. The US is a worrying outlier for Amazon, Oceana says. Globally, the e-commerce giant says that it reduced its use of plastic packaging 11.6 percent in 2022 compared to the prior year. But the US is the company's biggest market, and Oceana argues it's where Amazon needs to make a lot more progress.

Only 57 Companies Produced 80% of Global Carbon Dioxide (carbonmajors.org) 167

Last year was the hottest on record and the Earth is headed towards a global warming of 2.7 degrees, yet top fossil fuel and cement producers show a disregard for climate change and actively make things worse. From a report: A new Carbon Majors Database report found that just 57 companies were responsible for 80 percent of the global carbon dioxide emissions between 2016 and 2022. Thirty-eight percent of total emissions during this period came from nation-states, 37 percent from state-owned entities and 25 percent from investor-owned companies.

Nearly 200 parties adopted the 2015 Paris Agreement, committing to reduce greenhouse gas emissions. However, 58 of the 100 state- and investor-owned companies in the Carbon Majors Database have increased their production in the years since (The Climate Accountability Institute launched Carbon Majors in 2013 to hold fossil fuel producers accountable and is hosted by InfluenceMap). This number represents producers worldwide, including 87 percent of those assessed in Asia, 57 percent in Europe and 43 percent in North America.

It's not a clear case of things slowly turning around, either. The International Energy Agency found coal consumption increased by eight percent over the seven years to 8.3 billion tons -- a record high. The report names state-owned Coal India as one of the top three carbon dioxide producers. Russia's state-owned energy company Gazprom and state-owned oil firm Saudi Aramco rounded out the trio of worst offenders.

NASA Picks 3 Companies to Help Astronauts Drive Around the Moon (nytimes.com) 23

NASA announced on Wednesday that they have selected three companies to develop preliminary designs for vehicles to take astronauts around the south polar region of the Moon. "After the astronauts return to Earth, these vehicles would be able to self-drive around as robotic explorers, similar to NASA's rovers on Mars," reports the New York Times. "The self-driving capability would also allow the vehicle to meet the next astronaut mission at a different location." From the report: The companies are Intuitive Machines of Houston, which in February successfully landed a robotic spacecraft on the moon; Lunar Outpost of Golden, Colo.; and Venturi Astrolab of Hawthorne, Calif. Only one of the three will actually build a vehicle for NASA and send it to the moon. NASA had asked for proposals of what it called the lunar terrain vehicle, or L.T.V., that could drive at speeds up to 9.3 miles per hour, travel a dozen miles on a single charge and allow astronauts to drive around for eight hours. The agency will work with the three companies for a year to further develop their designs. Then NASA will choose one of them for the demonstration phase. The L.T.V. will not be ready in time for the astronauts of Artemis III, the first landing in NASA's return-to-the-moon program, which is currently scheduled for 2026.

The plan is for the L.T.V. to be on the lunar surface ahead of Artemis V, the third astronaut landing that is expected in 2030, said Lara Kearney, manager of the extravehicular activity and human surface mobility program at the NASA Johnson Space Center. "If they can get there earlier, we'll take it earlier," Ms. Kearney said. The L.T.V. contract will be worth up to $4.6 billion over the next 15 years -- five years of development and then a decade of operations on the moon, most of it going to the winner of this competition. But Ms. Kearney said the contracts allow NASA to later finance the development of additional rovers, or allow other companies to compete in the future.

NASA To Create Time Standard For the Moon (reuters.com) 75

artmancc writes: The White House has directed NASA and other federal agencies to get to work on a plan to implement precision timekeeping and dissemination on the moon and elsewhere in space. Reuters cited a memo from the head of the White House Office of Science and Technology Policy (OSTP) that "instructed the space agency to work with other parts of the U.S. government to devise a plan by the end of 2026 for setting what it called a Coordinated Lunar Time (LTC). The name of the proposed time standard is similar to the terrestrial time standard known as Coordinated Universal Time (UTC).

"OSTP chief Arati Prabhakar's memo said that for a person on the moon, an Earth-based clock would appear to lose on average 58.7 microseconds per Earth-day and come with other periodic variations that would further drift moon time from Earth time," Reuters reported. An unidentified OSTP official said the lunar time standard is needed for secure and synchronized communication between astronauts, satellites orbiting the moon, and Earth.

Trash From the ISS May Have Hit a House In Florida (arstechnica.com) 135

A nearly two-pound piece of trash from the International Space Station may have hit a house in Florida. Alejandro Otero said it "tore through the roof and both floors of his two-story house in Naples, Florida," reports Ars Technica. "Otero wasn't home at the time, but his son was there." From the report: A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That's an important piece of information because it is a close match for the time -- 2:29 pm EST (19:29 UTC) -- that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida. This space junk consisted of depleted batteries from the ISS, attached to a cargo pallet that was originally supposed to come back to Earth in a controlled manner. But a series of delays meant this cargo pallet missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry.

Otero's likely encounter with space debris was first reported by WINK News, the CBS affiliate for southwest Florida. Since then, NASA has recovered the debris from the homeowner, according to Josh Finch, an agency spokesperson. Engineers at NASA's Kennedy Space Center will analyze the object "as soon as possible to determine its origin," Finch told Ars. "More information will be available once the analysis is complete." [...] In a post on X, Otero said he is waiting for communication from "the responsible agencies" to resolve the cost of damages to his home.

If the object is owned by NASA, Otero or his insurance company could make a claim against the federal government under the Federal Tort Claims Act, according to Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi. "It gets more interesting if this material is discovered to be not originally from the United States," she told Ars. "If it is a human-made space object which was launched into space by another country, which caused damage on Earth, that country would be absolutely liable to the homeowner for the damage caused." This could be an issue in this case. The batteries were owned by NASA, but they were attached to a pallet structure launched by Japan's space agency.

Record Heat in Europe, Asia Closes Another Extremely Warm Month For Planet (washingtonpost.com) 91

Earth has a long-running fever that shows little signs of easing. The planet has set high temperature records in each of the last nine months, and March is poised to become the 10th. From a report: Multiple locations around the world observed unprecedented heat on the month's final weekend, as if to put an exclamation mark on this exceptional run of warmth. The weekend heat was most widespread in Europe, where many countries set national high temperature records for March. But it was also unusually warm in Asia, parts of Central America and West Africa.

Human-caused climate change from the burning of coal, oil and natural gas is fueling this warmth, with an assist from the El Niño climate pattern. It felt more like summer than early spring in Eastern Europe over the weekend, with temperatures soaring into the 70s and 80s, about 20 to 35 degrees above normal. Eight countries set national records for March warmth.

Arizona's Governor Signs Bill Making Pluto the Official State Planet (azcapitoltimes.com) 118

"Be it enacted by the Legislature of the State of Arizona..." reads the official text of House Bill #2,477. "PLUTO IS THE OFFICIAL STATE PLANET."

An anonymous reader shared this report from Capital Media Services: The governor signed legislation Friday designating Pluto as Arizona's "official state planet." It joins a list of other items the state has declared to be "official,'' ranging from turquoise as the state gemstone and copper as the state metal to the Sonorasaurus as the state dinosaur. "I am proud of Arizona's pioneering work in space discovery," governor Hobbs said.

What makes Pluto unique and ripe for claim by Arizona is that it is the only planet actually discovered in the United States, and the discovery was made in Flagstaff. Rep. Justin Wilmeth, a Phoenix Republican and self-described "history nerd,'' said that needed to be commemorated, starting with the legacy of astronomer Clyde Tombaugh. In 1930, Tombaugh was working at the Lowell Observatory in Flagstaff. "The whole story of Clyde is just amazing, just sitting there under the telescope'' looking for planets by taking photos over a period of time, said Wilmeth. "It was two different glass planes that had one little spec of light moving in a different direction,'' showing it wasn't just another star — and all by observation and not computers. "To me, that's something that's just mind boggling."

"The International Astronomical Union voted years ago to strip Pluto of its official status as a planet," the article points out, noting that its official definition specifies that planets "clear the neighboring region of other objects." (While Pluto "has such a small gravitational pull, it has not attracted and absorbed other space rocks in its orbit".)

So in 2006 Pluto was reclassified as a dwarf planet, according to a NASA web page. "Pluto is about 1/6 the width of Earth," and has a radius of 715 miles or 1,151 kilometers. "If Earth was the size of a nickel, Pluto would be about as big as a popcorn kernel."

Long-time Slashdot reader Baron_Yam called Arizona's new legislation "How to advertise you are ignorant. Scientists said something we don't like, so we'll make a law!" They can call it their "State Planet" all they want, but people who actually know about the skies will be mocking them for it. While there is nostalgia for the old classification, and the new one isn't perfect... it's certainly more meaningful when trying to divide up the objects of a planetary system for study.
Reached for a comment by Capital Media Services, Representative Wilmeth said "It might matter to some that are going to get picky or persnickety about stuff... There's several generations of Americans ... who believe that Pluto's a planet — or at least that's what we were taught. I'm never going to think differently. That's just my personal opinion." (The news site adds that "What is important, Wilmeth said, is remembering the history and promoting it.")

Five senators in Arizona's state legislatur did vote against the measure — though not all of them did so for scientific reasons, Senator Anthony Kern explained to Capital Media Services. "I did not want to discriminate against those who wanted Mars, Venus, Jupiter, or everyone's favorite, Uranus."

After Outer Space, 93-Year-Old William Shatner Leads Cruise to Antarctica (space2sea.io) 51

"Sail to a continent as mysterious as outer-space itself," the new web site urges.

"William Shatner saw Earth from the highest view," writes Scripps News Service. "Now he's heading to the bottom of it — and inviting you to join him." The 93-year-old is setting sail for Antarctica on Dec. 19, which will mark just over three years since the "Star Trek" actor returned from a trip to space in real life, not just as Captain James T. Kirk. Fellow space traveler NASA astronaut Scott Kelly will join Shatner on the 10-day Space2Sea expedition, and 260 others can too — if they pay for their $37,500 ticket.

The cheapest suite — priced at $35,500 — along with the top three most expensive ones — reaching $91,500 — are already sold out. Presented by Future of Space, the trip aboard the new "ultra-luxury" vessel is said to be full of "awe-inspiring experiences," including "intimate encounters" with penguins, visits to remote historical locations and evenings full of stories from "esteemed guests," like Shatner. Travelers can also kayak the waters or go down deep under the ice in submersibles, both for additional charges...

Shatner said he experienced something called the "overview effect" while viewing the Earth from space. The overview effect, coined by space philosopher and author Frank White, refers to a shift in how astronauts think about our life on the planet, described by White as "the feeling that the Earth itself is a whole system, and we're just a part of it." It's also realizing through experience that there are no borders or boundaries on Earth. It's often marked by feelings of increased appreciation of the planet's beauty. Shatner's invitation to "fellow explorers" for the Space2Sea expedition seem to echo this phenomenon, with the actor saying he didn't expect to be "captivated by the fragile, blue curve of our planet" when flying on Blue Origin's rocket.

Thorium: The Fastest Open Source Chromium-based Browser? (itsfoss.com) 55

"After taking a look at Floorp Browser, I was left wondering whether there was a Chromium-based web browser that was as good, or even better than Chrome," writes a "First Look" reviewer at It's Foss News.

"That is when I came across Thorium, a web-browser that claims to be the 'the fastest browser on Earth'." [Thorium] is backed by a myriad of tweaks that include, compiler optimizations for SSE4.2, AVS, AES, various mods to CFLAGS, LDFLAGS, thinLTO flags, and more. The developer shares performance stats using popular benchmarking tools... I tested it using Speedometer 3.0 benchmark on Fedora 39 and compared it to Brave, and the scores were:

Thorium: 19.2; Brave: 19.5

So, it may not be the "fastest" always, probably one of the fastest, that comes close to Brave or sometimes even beats it (depends on the version you tested it and your system).

Alexander Frick, the lead developer, also insists on providing support for older operating systems such as Windows 7 so that its user base can use a capable modern browser without much fuss... As Thorium is a cross-platform web browser, you can find packages for a wide range of platforms such as Linux, Raspberry Pi, Windows, Android, macOS, and more.

Thorium can sync to your Google account to import your bookmarks, extensions, and themes, according to the article.

"Overall, I can confidently say that it is a web browser I could daily drive, if I were to ditch Chrome completely. It gels in quite well with the Google ecosystem and has a familiar user interface that doesn't get in the way."

Major Mobile NFT Shooter Game 'MadWorld' Uses Linux Foundation Subsidiary's Game Engine (linuxfoundation.org) 29

A Linux Foundation subsidiary has developed a free and open-source 3D game engine distributed under the Apache license. And last week the Open 3D Foundation announced "a big step forward, showcasing the power of open-source technologies in giving gamers around the globe unforgettable gaming experiences."

"We are proud to unveil MadWorld as the first mobile title powered by O3DE," said Joe Bryant, Executive Director of the Open 3D Foundation, "demonstrating the large potential of open-source technologies in game development."

And then this week Los Angeles Business Journal reported that El Segundo-based gaming studio Carbonated Inc. "has raised $11 million of series A funding to finance the development and release of its debut game title... Prior to its most recent round, Carbonated closed an $8.5 million seed funding round in 2020, which also included participation from Andreessen and Bitkraft." Since its founding [in 2015], the company has been focusing on research and development for its upcoming first title, called "MadWorld." The third-person, multiplayer shooter game is set in a post-apocalyptic world and features both player-versus-player and player-versus-environment features. Players of the game will battle for land control in a dystopian setting. Using a combination of open-source mapping tools and Carbonated's proprietary custom operations technology, called Carbyne, the game's world is designed around real-life cities and locations. Players are initially dropped into the game's version of their own real-time location.

The game allows players to optionally engage using blockchain technology with a digital asset-ownership layer powered by a blockchain network called XPLA.

Earlier this month Madworld "opened up for Early Access registration," reports the egamers web site, arguing that the game "is set to redefine the gaming landscape and will make its public debut later this year." After a catastrophic event named "The Collapse," MadWorld takes place in a desolate Earth where players engage in a battle for survival, highlighting the game's unique setting and immersive experience. The game's world is intricately designed with 250,000 land plots mapped out on a hexagonal grid, each presenting unique resources and strategic benefits. This innovative approach to game design enhances the gameplay experience and introduces a new layer of strategy and competition.

MadWorld's gameplay is centered around integrating Web3 technologies, which allows for the ownership, enhancement, and trading of tokenized representations of real-world locations. This feature encourages players to create clans and work together or compete for essential resources that are spread across the vast game world. Clans can acquire these resources by paying tributes to NFT landowners using "Rounds," the in-game currency. This mechanism not only fosters a sense of community and teamwork but also creates unique economic opportunities within the game by blending traditional gaming elements with the emerging field of digital assets.

"With its use of O3DE, Carbonated can enhance the game's visual fidelity, performance, and scalability," according to the Linux Foundation's announcement, "in order to deliver a fast-paced adventure on mobile platforms." O3DE is an open-source game engine developed by a collaborative community of industry experts. It includes state-of-the-art rendering capabilities, dynamic lighting, and realistic physics simulation. These features have enabled Carbonated to build realistic dystopian environments and create action-packed gameplay in MadWorld.
According to its official site, MadWorld "is set to be released to the public sometime in 2024 and is currently being tested on iOS and Android operating systems."

Carbonated's CEO Travis Boatman made this prediction to the site Decrypt. "We think mobile is where the breakout will happen for Web3."

Bill Gates Says Texas Shows America's Clean-Energy Future (gatesnotes.com) 120

"If you want to see what the cutting edge of next-gen clean energy innovation looks like, it'd be hard to find a place better than Texas," Bill Gates wrote recently on his blog," saying "amazing companies" are breaking ground across the state. "Each one represents a huge boon for the local economy, America's energy security, and the fight against climate change." The world is undergoing an energy transition right now, fueled by the development and deployment of new clean energy technologies. The pace of innovation at the heart of this transition is happening faster than many people (including me!) dared hope. The progress makes me optimistic about the future — and excited about the role that American communities will play, especially in places like Texas.

Breakthrough Energy and I have invested more than $130 million into Texas-based entrepreneurs, institutions, and projects. It's a big bet, but it's one I'm confident in. Why? Because of the people. Nearly half a million Texans work in the oil and gas industry, and their skills are directly transferrable to next-generation industries. This workforce will help form the backbone of the world's new clean energy economy, and it will cement Texas's energy leadership for generations to come.

Many of the companies I'm seeing on this trip already employ or plan to employ oil and gas workers. One of those companies is Infinium, which is working on next-generation clean fuels for trucks, ships, and even planes. I'm visiting their first demonstration plant in Corpus Christi, where they're turning waste CO2 and renewable energy into electrofuels — or eFuels — for trucks. They've already signed a deal with Amazon, and sometime soon, if you live in the area, you might get a delivery supported by Infinium eDiesel. The key to Infinium's approach is that their fuels can be dropped into existing engines... I'm especially excited about the work they're doing on sustainable aviation fuel, or SAF — which could reduce emissions from air travel by as much as 90 percent, according to company estimates. Infinium is in the process of converting an old gas-to-liquid plant in West Texas into a new facility that will increase the company's capacity for producing eFuels ten-fold. Breakthrough Energy's Catalyst program has invested in this first-of-its-kind plant, and I can't wait to see it when it's done.

Another company I'll see is Mars Materials. They're a Breakthrough Energy Fellows project working on a different way to reuse CO2. The company is developing a clever technique for turning captured carbon into one of the key components in carbon fiber, an ultra-light, ultra-strong material that is used in everything from clothing to car frames... The Mars Materials team relocated from California to Texas in part because of the skilled oil and gas talent that they could access in the state, and they aren't the first Breakthrough Energy company to do that. I'm going to check out their lab, where their scientists are hard at work optimizing the conversion process.

Both companies assume abundant CO2, Gates writes, but "fortunately for them, Texas is also in the process of becoming a capital for direct air capture... A recent study found that Texas has the greatest DAC deployment potential in the country and could create as many as 400,000 jobs by 2050." Already a direct air capture "hub" in Kingsville, Texas is expected to create 2,500 jobs over the next five years, while Houston has been selected as the site for one of America's seven Regional Clean Hydrogen Hubs.

"If you want to catch a glimpse of our country's clean energy future," Gates writes, "you should head on down to the Lone Star State."

Henrietta Leavitt, Cosmology Pioneer, Receives Belated Obituary (nytimes.com) 14

Longtime Slashdot reader necro81 writes: The New York Times has an occasional series called "Overlooked," whereby notable people whose deaths were overlooked at the time receive the obituary they deserve. Their latest installment eulogizes Henrietta Swan Leavitt, who passed away in 1921 at age 53. From the report: "In the early 20th century, when Henrietta Leavitt began studying photographs of distant stars at the Harvard College Observatory, astronomers had no idea how big the universe was... Leavitt, working as a poorly paid member of a team of mostly women [computers] who cataloged data for the scientists at the observatory, found a way to peer out into the great unknown and measure it."

Leavitt discovered the period-luminosity relationship for Cepheid variable stars. The relationship, now known as Leavitt's Law, is a crucial rung in the cosmic distance ladder, the methods for measuring the distance to stars, galaxies, and across the visible universe. From the report: "[Leavitt's Law] underpinned the research of other pioneering astronomers, including Edwin Hubble and Harlow Shapley, whose work in the years after World War I demolished long-held ideas about our solar system's place in the cosmos. Leavitt's Law has been used on the Hubble Telescope and the James Webb Space Telescope in making new calculations about the rate of expansion of the universe and the proximity of stars billions of light years from earth. 'She cracked into something that was not only impressive scientifically but shifted an entire paradigm of thinking...'"
