CNN reports: The popular theory that comets were crucial in kick-starting life on Earth billions of years ago may not hold up, according to new computer simulations that counter decades of scientific thinking. The finding suggests the fragile organic molecules supposedly carried by the icy objects would have been destroyed on impact, upending an established origin of life theory that dates back to at least 1961 [with earlier versions postulated in 1908]... Early in its history — over 4 billion years ago — Earth may have experienced a period of heavy bombardment from more than 100,000 comets larger than 100 meters (328 feet), according to the new study, published Wednesday in the journal Scientific Reports. Those impacts, however, were mostly too heavy for life-starting molecules to withstand. The team used the latest models of comet formation and evolution to simulate this early planetary period 100,000 times. "Given what we know about surface environments on the early Earth, on average, our simulations found that there were no successful impacts," said lead study author Richard Anslow, who conducted the research while completing his doctorate at the Institute of Astronomy of the University of Cambridge in the United Kingdom... "The typical velocities of these comets when they impact the Earth meant that actually very few, if any, would have been able to deliver intact organic molecules, so comets actually don't seem to be as useful for prebiotic chemistry as was previously thought," Anslow said. More precisely, 54% of the simulations showed no impact at all, while the remaining 46% had at least one and a "tiny minority" returned up to three collisions, Anslow said. "We can't rule out confidently that there was never a successful impact — there could have been one of these fluke impacts." However, such flukes had to occur in a "perfect location" that already met several important conditions, including the presence of liquid water and other chemicals needed to support life. That combination makes the overall process unlikely, he added. The article notes his argument that even if a successful impact occurred, it's unlikely an important chemical like hydrogen cyanide (HCN) could survive the impact, and would've dissolved in an ocean impact. Plus, "many other precursor molecules are also needed, such as compounds that contain phosphorus and sulfur, but these are not routinely found in comets, Anslow said." An alternative cosmic source of organic material could have been asteroids, which typically struck Earth more slowly and in greater numbers. Anslow pointed to recent findings on samples from asteroids Bennu and Ryugu, which contain the majority of protein-building amino acids. The recent study also raises another intriguing possibility: While Earth may not have had the ideal conditions to foster HCN from comet impacts, ancient Mars might have been better suited. "Because Mars is much smaller than Earth and further away from the sun, the typical impact velocity of comets is much lower, so while these impacts on Earth were destroying most of the HCN, this wasn't the case so much for Mars," Anslow said. This idea could add another dimension to the long-standing question of whether the red planet once supported life. While the authors closely analyzed how HCN could have survived comet impact, the chemical may have undergone reactions before the icy bodies entered Earth's atmosphere, said Queenie Chan, an associate professor of Earth sciences at Royal Holloway University of London, who was not involved with the study. This process could have created biologically important compounds, such as those protein building blocks, that are less volatile and more likely to survive.

BBS-era "door" games are preserved by the site Break Into Chat, along with their history. Now the site's actually traced the origins of several ANSI art screens in the 1980s and "how different people later transformed the original images," starting from one of the most popular bulletin board systems in St. Louis, Missouri. Slashdot reader Kirkman14 writes: "Fire Escape" was curator of the authoritative list of bulletin board systems in St. Louis's area code and sysop of the area's most popular board. Like many sysops of that time, Fire Escape enlivened her bulletin board by finding and repurposing older ANSI art. Eventually her BBS had 18 different logon screens in its rotation, many of which featured flames or mushroom clouds or made liberal use of red and yellow. Break Into Chat follows the trail: Some, maybe even most, of Fire Escape's logon screens had actually been adapted from old school "public domain" ANSI art drawn in the late 1980s and early 1990s by folks such as Michael C. Ling, Lora Ruffner (aka "Ebony Eyes") and Violet Stymacks.... Stymacks was unusually generous with her ANSI art. When she first began drawing, she combed through Fidonet node lists looking for bulletin boards with interesting or inspiring names. When she found one, she would draw an ANSI screen that fit the board's theme, then send it to the sysop. Eventually, sysops began seeking her out, too. By late 1990, she claimed that 500 bulletin boards were using her screens. Three years later, that total had tripled, according to Boardwatch . I believe it — I have located more than 1,100 of her pieces so far. She was so prolific that it would be surprising if she hadn't reused or remixed her own work over the years... [D]id they intend for other people to do so? Or would they have considered such borrowing or adapting as "ripping" or just plain "stealing"? These questions have dogged the BBS, ASCII art, and ANSI art scenes from the beginning. A freelance writer named Patrick Grote grappled with this ethical dilemma in 1990. He had begun to publish archives of ANSI art that he had collected from various public messageboards and networks. But what were people allowed to do with the ANSI screens in these collections? Was it okay to modify them? "Tough call," Grote said. "I know some people copyright their screens by inserting a little '(C)' on it," Grote wrote in a README file included in these collections. "Is this 'true' copyrighting? I would say yes, but then again, I don't feel like having any legal action taken against me for using an ANSI screen. In my opinion, I would say leave the ones that say '(C)' alone, but make every effort to contact the artist and ask for permission...." When I corresponded with Fire Escape this year, she admitted her memory wasn't what it used to be, but felt certain that she had not asked any artists for permission because she didn't know who they were or how to reach them. "I figured if anyone had an issue, I'd just remove the screen," she said. "But no one ever said anything about it."

Companies like Google, Netflix, TikTok, and Meta may soon owe the French government, reports Tom's Hardware: France has approved a proposed tax that aims to tax the amount of internet data per gigabyte sent to French users in the country... According to minutes released by the National Assembly, members voted 11-10 in support of the motion on October 30 — which now means the new law has been added to the country's next budget, despite major opposition from the government side and the finance committee rapporteur. The latest amendment, introduced by socialist lawmaker Laurent Lhardit, could see content providers pay €0.055 (roughly $0.06) to the government for every gigabyte of content distributed to French users. With approximately 154 million users and counting in France, the proposal's authors say such a tax could generate around €10 billion ($11.2 billion) in annual revenue for the government. The said proposal, though yet to be passed as it must survive further parliamentary scrutiny, aims at companies that generate substantial internet traffic as opposed to taxing their advertising revenue, profits and subscriptions. Its explanatory notes particularly mention Google, Meta, Netflix, Amazon, and content delivery network Akamai as major potential contributors. Notably, TikTok and other similar platforms could fall under this broader scope depending on how these rules are applied. Internet service providers, including Orange Free and Liad, would be required to measure the volume of data and identify the companies responsible for sending it to French users. The Data will then be collected and submitted quarterly to France's tax administration under the supervision of telecommunications watchdog Arcep. The measure becomes law if it clears the remaining stages of France's budget process, the article points out, "with parliament scheduled to vote on the budget's first section in early November." "VideoLAN, the French nonprofit organization behind the VLC media player, warned that the proposed levy could cost it more than €1 million annually," reports CircleID. "Its response illustrates how traffic-based taxation could affect organizations distributing large volumes of data without corresponding commercial revenue."

The Hubble Space Telescope "will plunge back into the atmosphere in the early-to-mid-2030s," reports Ars Technica. So now NASA has released a Request For Information (RFI) "asking commercial companies for ideas on how to reboost, service, or a controlled disposal of Hubble." Specifically, NASA is looking for information about companies' current and near-term capabilities for capturing Hubble and boosting it to an altitude of at least 373 miles (600 km), enhancing the telescope's performance, or guiding Hubble to a controlled reentry. "The requirement includes that the boost and/or servicing mission must not harm the HST and that this mission is expected to occur by 2032," NASA wrote in the RFI. The contractor would be responsible for providing the launch vehicle, servicing spacecraft, mission operations, and "crew if applicable." NASA is not committing to buying a Hubble rescue mission, but officials want to know who might be interested in mounting such a mission, how much it would cost, and which companies would have a realistic shot at reaching Hubble before it falls out of orbit and burns up on reentry. Orbital dynamicists currently predict that it will likely happen in 2033 or 2034 without intervention, but reentry forecasts can change based on solar activity... A reboost to NASA's requirement of 373 miles (600 km) would likely keep Hubble in orbit for at least 25 more years. "NASA last raised the orbit of Hubble in 2002," the article points out, "when the Space Shuttle Columbia visited the observatory for a servicing mission." The final shuttle servicing flight in 2009 did not reboost the telescope's orbit, and with the retirement of the shuttle fleet two years later, Hubble has steadily lost altitude with no way to stave off eventual destruction... NASA's newer flagship observatories, sometimes described as successors to Hubble, are not actually one-for-one replacements. Hubble is tuned to observe the Universe in visible and ultraviolet light, while the Webb and Roman telescopes peer deeper into the infrared Universe. Astronomers will likely have to wait for the launch of NASA's Habitable Worlds Observatory in the 2040s for an improvement on Hubble's visible and ultraviolet vision.
