By our current definition of life, some crystals can be called alive. Alien life could be so strange, we don't even recognize it as life.

November 8, 20232 yr Robot Kills Man After Mistaking Him for Box of Vegetables https://www.thedailybeast.com/robot-kills-man-after-mistaking-him-for-box-of-vegetables Quote A robot meant to lift boxes at a pepper sorting plant in South Korea mistook a man for a box of vegetables and crushed him, according to the BBC, citing local media. The man, described as a robotics company employee, had been checking the sensors on the robot ahead of a test run at the plant in South Gyeongsang province planned for Wednesday. The test run had reportedly been pushed back two days due to the robot malfunctioning. As the employee worked late into the night to make sure the robot would function smoothly, the robotic arm grabbed him and forced him onto a conveyor belt, crushing his body. He was rushed to a hospital but succumbed to his injuries. Understandable, there are quite a few posters here that could be mistaken for a box of vegetables
November 16, 20232 yr NASA and Japan to launch world's 1st wooden satellite as soon as 2024. Why? https://www.livescience.com/space/space-exploration/nasa-and-japan-to-launch-worlds-1st-wooden-satellite-as-soon-as-2024-why Quote NASA and the Japan Aerospace Exploration Agency (JAXA) are planning to launch the world's first wooden satellite into space in a bid to make spaceflight more sustainable. LignoSat, a coffee mug-size satellite made from magnolia wood, is set to launch into Earth's orbit by summer 2024, according to the space agencies. Wood doesn't burn or rot in the lifeless vacuum of space, but it will incinerate into a fine ash upon reentry into Earth's atmosphere — making it a surprisingly useful, biodegradable material for future satellites. After successfully testing their wood samples aboard the International Space Station (ISS) earlier this year, the scientists believe the test satellite is fit for launch. Interesting idea. I like it.

November 28, 20232 yr Google’s new geothermal energy project is up and running A first-of-its-kind geothermal project is now up and running in Nevada, where it will help power Google’s data centers with clean energy. Google is partnering with startup Fervo, which has developed new technology for harnessing geothermal power. Since they’re using different tactics than traditional geothermal plants, it is a relatively small project with the capacity to generate 3.5 MW. For context, one megawatt is enough to meet the demand of roughly 750 homes. The project will feed electricity into the local grid that serves two of Google’s data centers outside of Las Vegas and Reno. It’s part of Google’s plan to run on carbon pollution-free electricity around the clock by 2030. To reach that goal, it’ll have to get more sources of clean energy online. And it sees geothermal as a key part of the future electricity mix that can fill in whenever wind and solar energy wane. https://www.theverge.com/2023/11/28/23972940/google-data-center-geothermal-energy
December 1, 20232 yr Author 18 hours ago, DaEagles4Life said: Interesting, but not sure how useful it really is. The subsonic speed means it's pretty useless against low level attack aircraft, unless they are pointed directly at it or are embarrassingly slow, like the A-10, while the quoted cost makes it prohibitive for targeting the dirt-cheap drones dropping grenades across the battlefield. There's also a lot left unsaid, like the cueing systems, actual guidance system, and the flight endurance. It appears it would be kick-ass against attack and transport helicopters, but that's a pretty small component of most militaries and battlefield targets. The fact that it is sold as recoverable is important, but even that can lead to issues... Pop quiz, hotshot. There's a drone aimed at a bus, and your Roadrunner might be able to intercept it (very doubtful) or go home to be used again (yuuuugely more certain). What do you do?

December 6, 20232 yr Incredible story. No antibiotics worked, so this woman turned to a natural enemy of bacteria to save her husband’s life In February 2016, infectious disease epidemiologist Steffanie Strathdee was holding her dying husband’s hand, watching him lose an exhausting fight against a deadly superbug infection. After months of ups and downs, doctors had just told her that her husband, Tom Patterson, was too racked with bacteria to live. "I told him, ‘Honey, we’re running out of time. I need to know if you want to live. I don’t even know if you can hear me, but if you can hear me and you want to live, please squeeze my hand.’ "All of a sudden, he squeezed really hard. And I thought, ‘Oh, great!’ And then I’m thinking, ‘Oh, crap! What am I going to do?’” What she accomplished next could easily be called miraculous. First, Strathdee found an obscure treatment that offered a glimmer of hope — fighting superbugs with phages, viruses created by nature to eat bacteria. Then she convinced phage scientists around the country to hunt and peck through molecular haystacks of sewage, bogs, ponds, the bilge of boats and other prime breeding grounds for bacteria and their viral opponents. The impossible goal: quickly find the few, exquisitely unique phages capable of fighting a specific strain of antibiotic-resistant bacteria literally eating her husband alive. Next, the US Food and Drug Administration had to greenlight this unproven cocktail of hope, and scientists had to purify the mixture so that it wouldn’t be deadly. Yet just three weeks later, Strathdee watched doctors intravenously inject the mixture into her husband’s body — and save his life. Their story is one of unrelenting perseverance and unbelievable good fortune. It’s a glowing tribute to the immense kindness of strangers. And it’s a story that just might save countless lives from the growing threat of antibiotic-resistant superbugs — maybe even your own. "It’s estimated that by 2050, 10 million people per year — that’s one person every three seconds — is going to be dying from a superbug infection,” Strathdee told an audience at Life Itself, a 2022 health and wellness event presented in partnership with CNN. "I’m here to tell you that the enemy of my enemy can be my friend. Viruses can be medicine.” A terrifying vacation During a Thanksgiving cruise on the Nile in 2015, Patterson was suddenly felled by severe stomach cramps. When a clinic in Egypt failed to help his worsening symptoms, Patterson was flown to Germany, where doctors discovered a grapefruit-size abdominal abscess filled with Acinetobacter baumannii, a virulent bacterium resistant to nearly all antibiotics. Found in the sands of the Middle East, the bacteria were blown into the wounds of American troops hit by roadside bombs during the Iraq War, earning the pathogen the nickname "Iraqibacter.” "Veterans would get shrapnel in their legs and bodies from IED explosions and were medevaced home to convalesce,” Strathdee told CNN, referring to improvised explosive devices. "Unfortunately, they brought their superbug with them. Sadly, many of them survived the bomb blasts but died from this deadly bacterium.” Today, Acinetobacter baumannii tops the World Health Organization’s list of dangerous pathogens for which new antibiotics are critically needed. "It’s something of a bacterial kleptomaniac. It’s really good at stealing antimicrobial resistance genes from other bacteria,” Strathdee said. "I started to realize that my husband was a lot sicker than I thought and that modern medicine had run out of antibiotics to treat him.” With the bacteria growing unchecked inside him, Patterson was soon medevaced to the couple’s hometown of San Diego, where he was a professor of psychiatry and Strathdee was the associate dean of global health sciences at the University of California, San Diego. "Tom was on a roller coaster — he’d get better for a few days, and then there would be a deterioration, and he would be very ill,” said Dr. Robert "Chip” Schooley, a leading infectious disease specialist at UC San Diego who was a longtime friend and colleague. As weeks turned into months, "Tom began developing multi-organ failure. He was sick enough that we could lose him any day.” Searching for a needle in a haystack After that reassuring hand squeeze from her husband, Strathdee sprang into action. Scouring the internet, she had already stumbled across a study by a Tbilisi, Georgia, researcher on the use of phages for treatment of drug-resistant bacteria. A phone call later, Strathdee discovered phage treatment was well established in former Soviet bloc countries but had been discounted long ago as "fringe science” in the West. "Phages are everywhere. There’s 10 million trillion trillion — that’s 10 to the power of 31 — phages that are thought to be on the planet,” Strathdee said. "They’re in soil, they’re in water, in our oceans and in our bodies, where they are the gatekeepers that keep our bacterial numbers in check. But you have to find the right phage to kill the bacterium that is causing the trouble.” Buoyed by her newfound knowledge, Strathdee began reaching out to scientists who worked with phages: "I wrote cold emails to total strangers, begging them for help,” she said at Life Itself. One stranger who quickly answered was Texas A&M University biochemist Ryland Young. He’d been working with phages for over 45 years. "You know the word persuasive? There’s nobody as persuasive as Steffanie,” said Young, a professor of biochemistry and biophysics who runs the lab at the university’s Center for Phage Technology. "We just dropped everything. No exaggeration, people were literally working 24/7, screening 100 different environmental samples to find just a couple of new phages.” ‘No problem’ While the Texas lab burned the midnight oil, Schooley tried to obtain FDA approval for the injection of the phage cocktail into Patterson. Because phage therapy has not undergone clinical trials in the United States, each case of "compassionate use” required a good deal of documentation. It’s a process that can consume precious time. But the woman who answered the phone at the FDA said, “‘No problem. This is what you need, and we can arrange that,’” Schooley recalled. "And then she tells me she has friends in the Navy that might be able to find some phages for us as well.” In fact, the US Naval Medical Research Center had banks of phages gathered from seaports around the world. Scientists there began to hunt for a match, "and it wasn’t long before they found a few phages that appeared to be active against the bacterium,” Strathdee said. Back in Texas, Young and his team had also gotten lucky. They found four promising phages that ravaged Patterson’s antibiotic-resistant bacteria in a test tube. Now the hard part began — figuring out how to separate the victorious phages from the soup of bacterial toxins left behind. "You put one virus particle into a culture, you go home for lunch, and if you’re lucky, you come back to a big shaking, liquid mess of dead bacteria parts among billions and billions of the virus,” Young said. "You want to inject those virus particles into the human bloodstream, but you’re starting with bacterial goo that’s just horrible. You would not want that injected into your body.” Purifying phage to be given intravenously was a process that no one had yet perfected in the US, Schooley said, "but both the Navy and Texas A&M got busy, and using different approaches figured out how to clean the phages to the point they could be given safely.” More hurdles: Legal staff at Texas A&M expressed concern about future lawsuits. "I remember the lawyer saying to me, ‘Let me see if I get this straight. You want to send unapproved viruses from this lab to be injected into a person who will probably die.’ And I said, "Yeah, that’s about it,’” Young said. "But Stephanie literally had speed dial numbers for the chancellor and all the people involved in human experimentation at UC San Diego. After she calls them, they basically called their counterparts at A&M, and suddenly they all began to work together,” Young added. "It was like the parting of the Red Sea — all the paperwork and hesitation disappeared.” ‘It was just miraculous’ The purified cocktail from Young’s lab was the first to arrive in San Diego. Strathdee watched as doctors injected the Texas phages into the pus-filled abscesses in Patterson’s abdomen before settling down for the agonizing wait. "We started with the abscesses because we didn’t know what would happen, and we didn’t want to kill him,” Schooley said. "We didn’t see any negative side effects; in fact, Tom seemed to be stabilizing a bit, so we continued the therapy every two hours.” Two days later, the Navy cocktail arrived. Those phages were injected into Patterson’s bloodstream to tackle the bacteria that had spread to the rest of his body. "We believe Tom was the first person to receive intravenous phage therapy to treat a systemic superbug infection in the US,” Strathdee told CNN. "And three days later, Tom lifted his head off the pillow out of a deep coma and kissed his daughter’s hand. It was just miraculous.” Damaged but not broken Today, nearly eight years later, Patterson is happily retired, walking 3 miles a day and gardening. But the long illness took its toll: He was diagnosed with diabetes and is now insulin dependent, with mild heart damage and gastrointestinal issues that affect his diet. "He isn’t back surfing again, because he can’t feel the bottoms of his feet, and he did get Covid-19 in April that landed him in the hospital because the bottoms of his lungs are essentially dead,” Strathdee said. "As soon as the infection hit his lungs he couldn’t breathe and I had to rush him to the hospital, so that was scary,” she said. "He remains high risk for Covid but we’re not letting that hold us hostage at home. He says, ‘I want to go back to having as normal life as fast as possible.’” To prove it, the couple are again traveling the world — they recently returned from a 12-day trip to Argentina. "We traveled with a friend who is an infectious disease doctor, which gave me peace of mind to know that if anything went sideways, we’d have an expert at hand,” Strathdee said. "I guess I’m a bit of a helicopter wife in that sense. Still, we’ve traveled to Costa Rica a couple of times, we’ve been to Africa, and we’re planning to go to Chile in January.”
