California Gives Final OK To Require Solar Panels On New Houses (npr.org) 563

Solar panels will be a required feature on new houses in California, after the state's Building Standards Commission gave final approval to a housing rule that's the first of its kind in the United States. From a report: Set to take effect in 2020, the new standard includes an exemption for houses that are often shaded from the sun. It also includes incentives for people to add a high-capacity battery to their home's electrical system, to store the sun's energy. "These provisions really are historic and will be a beacon of light for the rest of the country," said commissioner Kent Sasaki, according to The Mercury News. "[It's] the beginning of substantial improvement in how we produce energy and reduce the consumption of fossil fuels."

The rule marks a new phase in California's environmental policies, which have often set trends and established standards nationwide. The state has set the goal of drawing 100 percent of its electricity from renewable energy sources and sharply reducing greenhouse gas emissions. The solar panels rule was initially endorsed as part of the state's Green Building Standards Code by the California Energy Commission back in May.

Developer Misinterprets Linux Code of Conduct, Suggests Replacing F-Word with 'Hug' (neowin.net) 402

Seeking compliance with Linux's new Code of Conduct, Intel software engineer Jarkko Sakkinen recently requested comments on a set of changes to kernel code comments which Neowin described as "replacing the F-word with 'hug'. "

80 comments quickly followed on the Linux Kernel Maintainer's List: Several contributors responded to the alterations calling them insane. One wondered if Sakkinen was just trying to make a joke, and another called it censorship and said he'd refuse to apply any sort of patches like this to the code he's in charge of...

Some of the post-change comments read "Some Athlon laptops have really hugged PST tables", "If you don't see why, please stay the hug away from my code", and "Only Sun can take such nice parts and hug up the programming interface".

Eventually LWN.net publisher Jonathan Corbet deflated most of the controversy by pointing out that Linux's new Code of Conduct applies to future comments but clearly indicates that it does not apply explicitly to past comments.

And Jarkko Sakkinen acknowledged that he had missed that part of the discussion.

Controversial Spraying, Sun-Dimming Method Aims To Curb Global Warming (cbsnews.com) 256

Scientists are proposing an ingenious but as-yet-unproven way to tackle climate change: spraying sun-dimming chemicals into the Earth's atmosphere. From a report: A fleet of 100 planes making 4,000 worldwide missions per year could help save the world from climate change. Also, it may be relatively cheap. That's the conclusion of a new peer-reviewed study in Environmental Research Letters. It's the stuff of science fiction. Planes spraying tiny sulphate particulates into the lower stratosphere, around 60,000 feet up. The idea is to help shield the Earth from just enough sunlight to help keep temperatures low. The researchers examined how practical and costly a hypothetical solar geoengineering project would be beginning 15 years from now. The aim would be to half the temperature increase caused by heat-trapping greenhouse gases. This method would mimic what large volcanoes do. In 1991, Mount Pinatubo erupted in the Philippines. It was the second largest eruption of the 20th century, according to the United States Geological Survey (USGS). In total, the eruption injected 20 million tons of sulfur dioxide aerosols into the stratosphere. USGS said the Earth's lower atmosphere temperature dropped by approximately 1-degree Fahrenheit. The effect only lasted a couple of years because the sulfates eventually fell to Earth.

Nearby Star Is Sun's Long-Lost Sibling (syfy.com) 95

The Bad Astronomer writes: A nearby star, HD 186302, was almost certainly born from the same cloud of gas the Sun was 4.6 billion years ago. Astronomers have found it has an almost identical chemical composition as the Sun, is on a similar orbit around the Milky Way, and has the same age (within uncertainties). Interestingly, it's only 184 light years away, implying statistically many more such stars are waiting to be discovered.

Ford Patents a Way To Remove 'New Car Smell' (freep.com) 170

Ford has filed a patent for a method of eliminating the new car smell after a vehicle has been purchased. In the U.S., "new car smell" is beloved, but in China, customers find the odor disgusting. From a report: While the U.S. Patent and Trademark Office hasn't issued a ruling on the "vehicle odor remediation" patent application, and Ford hasn't committed to moving forward with the project, the paperwork explains what creates the odor so many Americans like: That new car smell is caused by volatile organic compounds given off by leather, plastic and vinyl. Chemicals used to attach and seal car parts may also contribute to the odor. People notice odors when compounds are released, which occurs when a car sits in high temperatures.

Ford scientists describe baking the car until the odor disappears, which happens after compounds are released. The process described in the patent involves parking the car in the sun, opening the windows slightly, and optionally turning the engine, heater and fan on.The system includes special software and various air quality sensors, and works only when fitted to a driverless or semi-autonomous vehicle. A lot of technology is involved in the patent application. The car would determine whether conditions are right to expel compounds, and the car would drive itself to a place in the sun and bake away the offensive odor.

NASA Decommissions the Kepler Space Telescope (space.com) 60

Late last month, NASA announced that it would be retiring the Kepler space telescope after nearly ten years of service -- double its initial mission life. Now, as Space.com reports, the planet-hunting telescope has been officially decommissioned, "beaming 'goodnight' commands to the sun-orbiting observatory." From the report: "Kepler's team disabled the safety modes that could inadvertently turn systems back on, and severed communications by shutting down the transmitters," NASA officials wrote in a statement today (Nov. 16). "Because the spacecraft is slowly spinning, the Kepler team had to carefully time the commands so that instructions would reach the spacecraft during periods of viable communication."

The final commands were sent from Kepler's operations center at the University of Colorado Boulder's Laboratory for Atmospheric and Space Physics, NASA officials said. The commands got to the spacecraft via NASA's Deep Space Network, the system of big radio dishes the space agency uses to keep in touch with its far-flung probes.

China's Fusion Reactor Reaches 100 Million Degrees Celsius (abc.net.au) 261

hackingbear shares a report from the Australian Broadcasting Corporation: The team of scientists from China's Institute of Plasma Physics announced this week that plasma in their Experimental Advanced Superconducting Tokamak (EAST) -- dubbed the 'artificial sun' -- reached a whopping 100 million degrees Celsius which is six times hotter than the core of the Sun. This temperature is the minimum required to maintain a fusion reaction that produces more power than it takes to run. The Chinese research team said they were able to achieve the record temperature through the use of various new techniques in heating and controlling the plasma, but could only maintain the state for around 10 seconds. The latest breakthrough provided experimental evidence that reaching the 100 million degrees Celsius mark is possible, according to China's Institute of Plasma Physics. "While the U.S. is putting new restrictions on nuclear technology exports to China, inventions and findings of EAST will be important contributions to the development of the International Thermonuclear Experimental Reactor (ITER)," writes Slashdot reader hackingbear. The reactor is currently being built in southern France with collaboration from 35 nations. According to the Australian Broadcasting Corporation, it is expected to be "the first device to consistently produce net energy, producing 500 megawatts of clean and sustainable power."

Large, Strangely Dim Galaxy Found Lurking On Far Side of Milky Way (sciencemag.org) 68

A reader shares a report from Science Magazine: Circling our galaxy is a stealthy giant. Astronomers have discovered a dwarf galaxy, called Antlia 2, that is one-third the size of the Milky Way itself. As big as the Large Magellanic Cloud, the galaxy's largest companion, Antlia 2 eluded detection until now because it is 10,000 times fainter. Such a strange beast challenges models of galaxy formation and dark matter, the unseen stuff that helps pull galaxies together. The galaxy was discovered with data from the European Space Agency's Gaia satellite, a space telescope measuring the motions and properties of more than 1 billion stars in and around the Milky Way. Gabriel Torrealba, an astronomy postdoc at the Academia Sinica in Taipei, decided to sift the data for RR Lyrae stars. These old stars, often found in dwarf galaxies, shine with a throbbing blue light that pulses at a rate signaling their inherent brightness, allowing researchers to pin down their distance.

Gaia data helped the team see past the foreground stars. Objects in the Milky Way's disk are close enough for Gaia to measure their parallax: a shift in their apparent position as Earth moves around the sun. More distant stars appear fixed in one spot. After removing the parallax-bearing stars, the researchers homed in on more than 100 red giant stars moving together in the constellation Antlia, they report in a paper posted to the preprint server arXiv this week. The giants mark out a sprawling companion galaxy 100 times less massive than anything of similar size, with far fewer stars.

Existing Laser Technology Could Be Fashioned Into Earth's 'Porch Light' To Attract Alien Astronomers, Study Finds (mit.edu) 257

If extraterrestrial intelligence exists somewhere in our galaxy, a new MIT study proposes that laser technology on Earth could, in principle, be fashioned into something of a planetary porch light -- a beacon strong enough to attract attention from as far as 20,000 light years away. From a report: The research, which author James Clark calls a "feasibility study," appears today in The Astrophysical Journal. The findings suggest that if a high-powered 1- to 2-megawatt laser were focused through a massive 30- to 45-meter telescope and aimed out into space, the combination would produce a beam of infrared radiation strong enough to stand out from the sun's energy. Such a signal could be detectable by alien astronomers performing a cursory survey of our section of the Milky Way -- especially if those astronomers live in nearby systems, such as around Proxima Centauri, the nearest star to Earth, or TRAPPIST-1, a star about 40 light-years away that hosts seven exoplanets, three of which are potentially habitable. If the signal is spotted from either of these nearby systems, the study finds, the same megawatt laser could be used to send a brief message in the form of pulses similar to Morse code.

Billionaires Are Chasing The Holy Grail of Energy: Fusion (bloombergquint.com) 185

Long-time Slashdot reader Zorro shared this article from Bloomberg: Not long before he died, tech visionary Paul Allen traveled to the south of France for a personal tour of a 35-country quest to replicate the workings of the Sun. The goal is to one day produce clean, almost limitless energy by fusing atoms together rather than splitting them apart. The Microsoft Corp. co-founder said he wanted to view the early stages of the International Thermonuclear Experimental Reactor in Cadarache firsthand, to witness preparations "for the birth of a star on Earth." Allen wasn't just a bystander in the hunt for the holy grail of nuclear power. He was among a growing number of ultra-rich clean-energy advocates pouring money into startups that are rushing to produce the first commercially viable fusion reactor long before the $23 billion ITER program's mid-century forecast. Jeff Bezos, Bill Gates and Peter Thiel are just three of the billionaires chasing what the late physicist Stephen Hawking called humankind's most promising technology.

Scientists have long known that fusion has the potential to revolutionize the energy industry, but development costs have been too high for all but a handful of governments and investors. Recent advances in exotic materials, 3D printing, machine learning and data processing are all changing that. "It's the SpaceX moment for fusion," said Christofer Mowry, who runs the Bezos-backed General Fusion Inc. near Vancouver, Canada. He was referring to Elon Musk's reusable-rocket maker. "If you care about climate change you have to care about the timescale and not just the ultimate solution. Governments aren't working with the urgency needed."

The company Allen supported, TAE Technologies, stood alone when it was incorporated as Tri-Alpha Energy two decades ago. Now it has at least two dozen rivals, many funded by investors with a track record of disruption. As a result, there's been an explosion of discoveries that are driving the kind of competition needed for a transformational breakthrough, according to Mowry.

The article reports one fusion company founded last year by six MIT professors is "confident they'll be able to produce a prototype of a so-called net energy reactor by 2025."

About That Monstrous Black Hole We're All Orbiting (theatlantic.com) 101

Astronomers on Wednesday reported new telescope observations of the environment around the Milky Way's supermassive black hole, named Sagittarius A*, pronounced "a-star," and they transformed the data into a lively animation. From a report: The video is positively ghostly. Clumps of gas swirl around the black hole, traveling at about 30 percent of the speed of light. Astronomers collected the data for the visualization using an instrument on the European Southern Observatory's Very Large Telescope, located in the deserts of northern Chile. The instrument, appropriately named GRAVITY, detected flares of infrared radiation coming from the disk surrounding Sagittarius A*. The researchers believe the bursts originated very close to the black hole, in an incredibly tumultuous region known as the innermost stable orbit. Here, cosmic material is slung around violently, but it remains far away enough that it can circle the black hole safely without getting sucked into the darkness.

If the thought of orbiting a monstrous, star-gobbling black hole spooks you, don't worry. Earth, located about two-thirds out from the center of the Milky Way, is at a very safe distance. The planet is in no danger of being consumed and wiped off the face of the universe. But, like everything else in the galaxy, it has long been subject to the black hole's whims. When black holes belch radiation out into space, the outflow can heat surrounding gas so much that it prevents it from cooling. If cosmic dust can't cool, it can't condense to form individual, brand-new stars, including ones like our sun. Scientists suspect that the fates of galaxies -- whether they produce new stars or stop altogether -- rests with the supermassive black holes at their centers.

Startling New Research Finds Large Buildup of Heat in the Oceans, Suggesting a Faster Rate of Global Warming [Update] (washingtonpost.com) 407

The world's oceans have been soaking up far more excess heat in recent decades than scientists realized, suggesting that Earth could be set to warm even faster than predicted in the years ahead, according to new research published Wednesday. From a report: Over the past quarter-century, the Earth's oceans have retained 60 percent more heat each year than scientists previously had thought, said Laure Resplandy, a geoscientist at Princeton University who led the startling study published Wednesday in the journal Nature. The difference represents an enormous amount of additional energy, originating from the sun and trapped by the Earth's atmosphere -- more than 8 times the world's energy consumption, year after year.

In the scientific realm, the new findings help to resolve long-running doubts about the rate of the warming of the oceans before 2007, when reliable measurements from devices called "Argo floats" were put to use worldwide. Before that, different types of temperature records -- and an overall lack of them -- contributed to murkiness about how quickly the oceans were heating up. The higher-than-expected amount of heat in the oceans means more heat is being retained within the Earth's climate system each year, rather than escaping into space. In essence, more heat in the oceans signals that global warming itself is more advanced than scientists thought.

"We thought that we got away with not a lot of warming in both the ocean and the atmosphere for the amount of CO2 that we emitted," said Resplandy, who published the work with experts from the Scripps Institution of Oceanography and several other institutions in the U.S., China, France and Germany. "But we were wrong. The planet warmed more than we thought. It was hidden from us just because we didn't sample it right. But it was there. It was in the ocean already." Wednesday's study also could have important policy implications. If ocean temperatures are rising more rapidly than previously calculated, that could leave nations even less time to dramatically cut the world's emissions of carbon dioxide, in hopes of limiting global warming to the ambitious goal of 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial levels.

With Fuel Exhausted, NASA Retires Kepler Telescope (space.com) 124

ewhac writes: NASA today announced that it is retiring the Kepler telescope after nearly ten years of service -- double its initial mission life. In that time, Kepler discovered over 2,600 exoplanets, most of which are between the size of Earth and Neptune, sparking an entirely new field of astronomical research, and revealing for the first time just how common exo-planetary systems are. With its fuel supply exhausted, Kepler is no longer able to maneuver or reorient itself to make observations. NASA has elected to decommission the spacecraft and leave it in its current, safe orbit away from Earth.

Climate Modeller Wins $10,000 Wager Against Solar Physicists, Fails To Collect (blogspot.com) 195

Layzej writes: Back in 2005, solar physicists Galina Mashnich and Vladimir Bashkirtsev made a $10,000 bet that global temperatures, driven primarily by changes in the Sun's activity, would fall over the next decade. The bet would compare the then record hot years between 1998 to 2003 with that between between 2012 and 2017. With temperatures falling from their peak during the 1998 super El-Nino, and solar output continuing to fall, this seemed like a sure bet. The results are now in and all datasets show that climate modeler James Annan is the clear winner.

At the time of the wager, Annan had supposed that the reputation of the scientists involved would be enough to ensure payment once the bet was settled. Unfortunately, as was the case with Alfred Russel Wallace's famous 1870 bet against flat-Earthers, the losing parties have refused to pay up.

"More precisely, Bashkirtsev is refusing to pay," writes the climate modeler on his blog, "and Mashnich is refusing to even reply to email.

"With impressive chutzpah, Bashkirtsev proposed we should arrange a follow-up bet which he would promise to honour."

NASA Has Explored Manned Missions To Venus (newsweek.com) 122

NASA recently developed a program for manned missions to explore Venus -- even though the planet's surface is 860 degrees, which NASA explains is "hot enough to melt lead." Long-time Slashdot reader Zorro shares this week's article from Newsweek: As surprising as it may seem, the upper atmosphere of Venus is the most Earth-like location in the solar system. Between altitudes of 30 miles and 40 miles, the pressure and temperature can be compared to regions of the Earth's lower atmosphere. The atmospheric pressure in the Venusian atmosphere at 34 miles is about half that of the pressure at sea level on Earth. In fact you would be fine without a pressure suit, as this is roughly equivalent to the air pressure you would encounter at the summit of Mount Kilimanjaro.

Nor would you need to insulate yourself as the temperature here ranges between 68 degrees Fahrenheit and 86 degrees Fahrenheit. The atmosphere above this altitude is also dense enough to protect astronauts from ionising radiation from space. The closer proximity of the sun provides an even greater abundance of available solar radiation than on Earth, which can be used to generate power (approximately 1.4 times greater).... [C]onceivably you could go for a walk on a platform outside the airship, carrying only your air supply and wearing a chemical hazard suit.

Venus is 8 million miles closer to Earth than Mars (though it's 100 times further away than the moon). But the atmosphere around Venus contains traces of sulphuric acid (responsible for its dense clouds), so the vessel would need to be corrosion-resistant material like teflon. (One NASA paper explored the possibility of airbone microbes living in Venus's atmosphere.) There's a slick video from NASA's Langley Research Center titled "A way to explore Venus" showcasing HAVOC -- "High Altitude Venus Operational Concept."

"A recent internal NASA study...led to the development of an evolutionary program for the exploration of Venus," explains the project's page at NASA.gov, "with focus on the mission architecture and vehicle concept for a 30 day crewed mission into Venus's atmosphere." NASA describes the project as "no longer active," though adding that manned missions to the atmosphere of Venus are possible "with advances in technology and further refinement of the concept."

Spacecraft BepiColombo Poised For Mission To Mercury 29

The European Space Agency is launching a spacecraft to explore the mysteries of Mercury. BepiColombo, named after the Italian mathematician and engineer Giuseppe "Bepi" Colombo, is set to launch at 9:45 p.m. ET Friday aboard an Ariane 5 rocket from a spaceport in French Guiana. The launch will be livestreamed via ESA's website. NPR reports: The spacecraft is actually made up of two probes: One will go into orbit close to the planet, while the other, supplied by the Japan Aerospace Exploration Agency, will orbit farther away, measuring Mercury's magnetic field. "What this lets you do is look at that space environment around Mercury from two different perspectives at exactly the same time," says Nancy Chabot, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory. That gives a clearer picture of what's changing during the 88 days it takes Mercury to make one revolution around the sun.

Radar measurements from Earth first suggested that there was ice on Mercury. Earlier this decade, NASA's Messenger mission was able to confirm that the ice was actually there. But Messenger only came close enough to see the ice at Mercury's north pole. The real icy action, Chabot says, is at the south pole. "The largest crater to host these water ice deposits is right smack dab at the south pole of Mercury," she says. "And so I'm very excited that BepiColombo is going to be in an orbit that passes much closer to the southern hemisphere." BepiColombo will take a rather circuitous path to Mercury. It will fly by Earth once, Venus twice and Mercury six times before it is in the right orientation to go into orbit around the innermost planet in our solar system. The entire trip will take slightly more than seven years.
When BepiColombo gets into orbit, it may be able to see where Messenger crash-landed on the planet. It is estimated to have made a crater about 60 feet across.

UPDATE: BepiColombo successfully blasted off from Europe's spaceport in French Guiana, marking the third ever mission to Mercury. "Launching BepiColombo is a huge milestone for ESA (the European Space Agency) and JAXA, and there will be many great successes to come," ESA Director General Jan Woerner said in a statement. "Beyond completing the challenging journey, this mission will return a huge bounty of science."

How Paul Allen Saved the American Search For Extraterrestrial Intelligence (vice.com) 48

dmoberhaus writes: Paul Allen died on Monday evening at the age of 65. Motherboard spoke with SETI researchers about how the Microsoft co-founder single-handedly saved the American Search for Extraterrestrial Intelligence by building the first dedicated SETI radio telescope and its legacy one decade later. Less than a year after NASA's SETI program started, it was shut down by members of Congress who didn't want to spend money on the "great Martian chase." In order for the program to continue, it needed private funding. "Fortunately, one of the earliest SETI Institute supporters was Barney Oliver, who founded and directed Hewlett Packard laboratories," reports Motherboard. "So in 1993 Oliver called Bill Hewlett and David Packard of Hewlett Packard, Intel founder Gordon Moore, and Paul Allen to ask for their support." They supported Project Phoenix, a SETI program that ran from 1995 to 1998.

SETI astronomers then realized that they needed a dedicated SETI radio telescope, or array of small telescopes, if the search were to have any chance of success. Allen was able to foot the $25-million bill required to build this array of telescopes. The telescope array was built in northern California, "the first facility specifically built for SETI in the U.S.," Motherboard notes. "The cost of building a 350-telescope array ended up being far more expensive than anyone at the SETI Institute had anticipated, however. By the time the Allen Telescope Array came online in 2007, only 42 telescopes had been built and Allen's donation had largely been consumed." The report notes that the Allen Telescope Array "has analyzed 200 million signals from thousands of stars, studied unusual high-energy radio emissions, and even scanned the "spliff-shaped" Oumuamua asteroid for signs of intelligent life."

Scientists Have Laid Out a Plan To Search For Life in the Universe (qz.com) 59

An anonymous reader shares a report: A blue-ribbon panel of researchers chaired by the University of Toronto's Barbara Sherwood Lollar assembled the report at the behest of the US Congress, which asked in a 2017 law that a "strategy for astrobiology" be developed to prioritize "the search for life's origin, evolution, distribution, and future in the universe." The 196-page report does not offer easy access to ET, but the steady drumbeat of scientific advancement it documents suggests an increasingly sophisticated understanding of what we know -- and don't know -- about biology on our planet and beyond.

Indeed, the recently gained knowledge it highlights is the front end of a wave: Only the Viking mission in the 1970s hunted rigorously for signs of life on other planets, and now the first new NASA mission to do so, the Europa lander, is being designed. In the past four years alone, scientists using data gathered by space probes on Mars discovered evidence of past surface water, the presence of nutrients and organic molecules, and methane gas in the atmosphere that varies by season. This doesn't mean life exists now on Mars, but it is helping contribute to an understanding of astrobiology as a discipline that looks at physical and chemical processes over time to determine if the conditions for life once existed or may do so in the future.

Much work on astrobiology is Earth-focused; it is the only place we know life exists and thus is our guinea pig for detecting life from a distance. The Galileo space probe found signs of life on our planet in 1990. The report stressed that recent discoveries of life on Earth that exists without the sun's energy, deep under the ocean or the ground, should inform what we look for on other worlds. Scientists are expanding their understanding of habitability beyond a binary and into a spectrum, which may sound trite, but previous research relied on blunt instruments and blunter assumptions about alien life -- starting with the idea that it would appear on the surface.

Bees Stop Flying During Total Solar Eclipses (smithsonianmag.com) 86

A new study published by the Entomological Society of America found that bees stop flying when the moon obstructs the sun during a total solar eclipse. "Using tiny microphones suspended among flowers, the team recorded the buzzing of the bees through all stages of the eclipse," reports Smithsonian Magazine. "The bees were active and noisy right up to the last moments before totality, the part of a total solar eclipse when the moon blocks all direct sunlight, and a night-like darkness settles over the land. As totality hit, the bees went totally silent in unison." From the report: The clear drop from buzzing to silence was the most striking change during the eclipse, but additional, smaller changes in the bees' buzzing could give the researchers clues about how the insects responded. As ecologist Candace Galen of the University of Missouri notes, the bees' buzzes lasted longer as it gradually got darker approaching totality. Increased buzz length suggests the bees started flying more slowly, they were taking longer flights, or some combination of both.

"The way I think about it is, if you're driving on a road and it gets foggy, you slow down," explains Galen. When there is less visibility, slowing down helps you process information and maintain situational awareness -- and like the bees did during totality, if there's absolutely zero visibility, you should probably pull over. Adjusting speed to acclimate one's senses to an environment that suddenly shifts is a common behavior in many animals, and it's been observed in bees when they fly before sunrise or sunset.
