Randall Munroe does more than draw the online comic strip XKCD. He's also published a funny new speculative science book (following up on his previous New York Times best-seller), promising "short answers, new lists of weird and worrying questions, and some of my favorite answers from the What If site."

From his blog: In What If 2, I answer new questions I've receieved in the years since What If? was released. People have asked about touching exotic materials, traveling across space and time, eating things they shouldn't, and smashing large objects into the Earth. There are questions about lasers, explosions, swingsets, candy, and soup. Several planets are destroyed — one of them by the soup.
But besides launching a new book tour, he's also found some particularly geeky ways to promote the new book. On Thursday Munroe went on a language podcast to ask his own oddball questions — like how to spot an artificial language, and what does the word "it" refer to in the sentence "It's 3pm and hot." He's illustrated a a science-y animated video, and released several self-mocking cartoons.

And of course — answered some more strange science questions.

First, a rumor from the blog Phone Arena. "Not to be outdone by Apple and Huawei, Samsung is planning to incorporate satellite connectivity options in its Galaxy phones as well, hints leakster Ricciolo."

But it's not the first rumor we've heard about phone vendors and satellites. "Cringley Predicts Apple is About to Create a Satellite-Based IoT Business ," read the headline in June. Long-time tech pundit Robert X. Cringely predicted that Apple would first offer some limited satellite-based functionality,

But he'd also called those services "proxies for Apple entering — and then dominating — the Internet of Things (IoT) business. "After all, iPhones will give them 1.6 billion points of presence for AirTag detection even on sailboats in the middle of the ocean — or on the South Pole.... Ubiquity (being able to track anything in near real time anywhere on the planet) signals the maturity of IoT, turning it quickly into a $1 TRILLION business — in this case Apple's $1 TRILLION business." And beyond that, "in the longer run Cupertino plans to dis-intermediate the mobile carriers — becoming themselves a satellite-based global phone and data company [and] they will also compete with satellite Internet providers like Starlink, OneWeb, and Amazon's Kuiper."

So how did Cringely react last week when Apple announced "Emergency SOS" messaging for the iPhone 14 and 14 Plus — via communication satellites — when their users are out of range of a cell signals? He began by wondering if Apple was intentionally downplaying the satellite features: They limited their usage case to emergency SOS texts in the USA and Canada, sorta said it would be just for iPhone 14s, and be free for only the first two years. They showed a satellite app and very deliberately tried to make it look difficult to use. They gave no technical details and there was no talk of industry partners.

Yet there were hints of what's to come. We (you and I, based on my previous column) already knew, for example, that ANY iPhone can be made to work with Globalstar. We also knew the deal was with Globalstar, which Apple never mentioned but Globalstar confirmed, more or less, later in the day in an SEC filing. But Apple DID mention Find My and Air Tags, notably saying they'd work through the satellites even without having to first beseech the sky with an app. So the app is less than it seems and Apple's satellite network will quickly find its use for the Internet of Things [Cringely predicts]....

Apple very specifically said nothing about the global reach of Find My and Air Tags. There is no reason why those services can't have immediate global satellite support, given that the notification system is entirely within Apple's ecosystem and is not dependent on 911-type public safety agreements.

Maybe it will take a couple years to cover the world with SOS, but not for Find My, which means not for IoT — a business headed fast toward $1 trillion and will therefore [hypothetically] have a near-immediate impact on Apple's bottom line.
Speculating further, Cringely predicts that Globalstar — which has ended up with vast tracts of licensed spectrum — will eventually be purchased by a larger company. ("If not Apple, maybe Elon Musk.")

And this leads Cringely to yet another prediction. "If Elon can't get Globalstar, he and his partners will push for the regulatory expansion into space of terrestrial 5G licenses, which will probably be successful." This will happen, frankly, whether SpaceX and T-Mobile are successful or not, because AST&Science and its investors AT&T, Verizon and Zodafone need 5G in space, too, to compete with Apple. So there WILL eventually be satellite competition for Apple and I think the International Telecommunication Union will eventually succumb to industry pressure.
And by the end Cringely is also speculating about just how Apple will come up with innovative new satellite designs on a faster schedule...

Nanoracks just made space construction and manufacturing history with the first demonstration of cutting metal in orbit. TechCrunch reports: The experiment was performed back in May by Nanoracks and its parent company Voyager Space, after getting to orbit aboard the SpaceX Transporter 5 launch. The company only recently released additional details on Friday. The goal of Outpost Mars Demo-1 mission was to cut a piece of corrosion-resistant metal, similar to the outer shell of United Launch Alliance's Vulcan Centaur and common in space debris, using a technique called friction milling. Welding and metal-cutting is a messy operation on Earth, but all of that dust and debris simply falls to the ground. But "when you're in space, in the vacuum, it doesn't really do that. It doesn't just float away necessarily either," Marshall Smith, Nanoracks' senior VP of space systems, explained to TechCrunch back in May. "What you want to do is to contain this debris, not necessarily because it might be a micrometeorites issue, which it could be as well, but mostly because you want to keep your work environment clean."

The entire demonstration lasted around one minute. The main goal -- to cut a single small sample of the steel -- was successfully completed. Inside the spacecraft were two additional samples to cut as a "reach goal," and Nanoracks is investigating why they weren't cut as well. It was conducted in partnership with Maxar Technologies, who developed the robotic arm that executed the cut. That arm used a commercially available friction milling end-effector, and the entire structure was contained in the Outpost spacecraft to ensure that no debris escaped. Indeed, one of the main goals of the demonstration was to produce no debris -- and it worked. Nanoracks used a type of metal similar to an upper stage of a rocket precisely because the company's long-term goal is to modify used upper stages and convert them into orbital platforms, or what it calls "outposts." According to Smith, this is just the beginning. In the future, Nanoracks will attempt cuts on a larger scale in its quest to eventually conduct larger construction efforts.

Intellia Therapeutics reported encouraging early-stage study results for its Crispr gene-editing treatments, the latest sign that the pathbreaking technology could result in commercially available drugs in the coming years. The Wall Street Journal reports: Intellia said Friday that one of its treatments, code-named NTLA-2002, significantly reduced levels of a protein that causes periodic attacks of swelling in six patients with a rare genetic disease called hereditary angioedema, or HAE. In a separate study building on previously released trial data, Intellia's treatment NTLA-2001 reduced a disease-causing protein by more than 90% in 12 people with transthyretin-mediated amyloidosis cardiomyopathy, or ATTR-CM, a genetic disease that can lead to heart failure.

Despite the positive results, questions remain about whether therapies based on Crispr will work safely and effectively, analysts said. Intellia's latest studies involved a small number of patients, and were disclosed in news releases and haven't been published in a peer-reviewed journal. The NTLA-2002 study results were presented at the Bradykinin Symposium in Berlin, a medical meeting focused on angioedema. The data came from small, so-called Phase 1 studies conducted in New Zealand and the U.K. that didn't include control groups. Results from such early studies can be unreliable predictors of a drug's safety and effectiveness once the compound is tested in larger numbers of patients. The findings, nevertheless, add to preliminary but promising evidence of the potential for drugs based on the gene-editing technology. Last year, Intellia said that NTLA-2001 reduced the disease-causing protein involved in ATTR patients.

Monitoring the last wild Chittenango ovate amber snails, scientists tiptoe through a waterfall spray zone the size of a living room. From a report: The Chittenango Creek, which runs north for about 30 twisting miles in central New York, has few distinguishing markers: The stream is generally only a couple of feet deep, and the towns it passes through are similarly small and overlooked. One exception is found a couple miles from the source of the creek, where the riverbed flattens out and drops 167 feet over a series of limestone cliffs that are segmented into ledges and still smaller rock shelves. The fractal qualities are magnified by the foaming water that tumbles in thin layers down the cliffs. On some mornings, sunlight from the southeast illuminates the mist, and the whole area glows. Around this time on a recent Thursday, a dozen people clustered on one side of the falls, along two ledges that were blanketed in snakeroot, yellow jewelweed, spotted Joe-Pye weed and pale swallowwort. Here, in an area about the size of a living room, is the only known habitat of a small, critically endangered invertebrate with a marbled spiral shell: the Chittenango ovate amber snail.

A thousand species of land snail worldwide are known to be at risk of extinction. Most have very specific needs and a limited geological range, so scientists have been studying their populations to understand how changes in the environment could affect biodiversity more broadly. "Land snails are apt to be the real canaries in the coal mine for these sorts of changes," said Rebecca Rundell, a biologist at the SUNY College of Environmental Science and Forestry. Dr. Rundell is conducting such research on endangered land snails in the Republic of Palau, and similar projects are underway in such far-flung places as Hawaii and Bermuda. But the same issues are at play in her backyard, with the "Chits," which can only flourish in nearly 100 percent humidity and the shade of deciduous forests. "The conservation status of our local snail is emblematic of what is happening to land snails globally," she said. And so Dr. Rundell's team, with volunteers and employees from the New York Department of Environmental Conservation, gathered on the side of the waterfall, their feet and knees planted cautiously but firmly on rocks, and sifted gently through the dirt and roots. Their goal: to figure out how many of these snails remain in the wild without crushing any in the process.

Blue light from artificial sources is on the rise, which may have negative consequences for human health and the wider environment, according to a study. From a report: Academics at the University of Exeter have identified a shift in the kind of lighting technologies European countries are using at night to brighten streets and buildings. Using images produced by the International Space Station (ISS), they have found that the orange-coloured emissions from older sodium lights are rapidly being replaced by white-coloured emissions produced by LEDs. While LED lighting is more energy-efficient and costs less to run, the researchers say the increased blue light radiation associated with it is causing "substantial biological impacts" across the continent. The study also claims that previous research into the effects of light pollution have underestimated the impacts of blue light radiation.

Chief among the health consequences of blue light is its ability to suppress the production of melatonin, the hormone that regulates sleep patterns in humans and other organisms. Numerous scientific studies have warned that increased exposure to artificial blue light can worsen people's sleeping habits, which in turn can lead to a variety of chronic health conditions over time. The increase in blue light radiation in Europe has also reduced the visibility of stars in the night sky, which the study says "may have impacts on people's sense of nature." Blue light can also alter the behavioural patterns of animals including bats and moths, as it can change their movements towards or away from light sources.

The world has never been in a better position to end the COVID-19 pandemic, the head of the World Health Organization said on Wednesday, his most optimistic outlook yet on the years-long health crisis which has killed over six million people. From a report: "We are not there yet. But the end is in sight," WHO Director-General Tedros Adhanom Ghebreyesus told reporters at a virtual press conference. That was the most upbeat assessment from the UN agency since it declared an international emergency in January 2020 and started describing COVID-19 as a pandemic three months later. The virus, which emerged in China in late 2019, has killed nearly 6.5 million people and infected 606 million, roiling global economies and overwhelming healthcare systems. The rollout of vaccines and therapies have helped to stem deaths and hospitalisations, and the Omicron variant which emerged late last year causes less severe disease. Deaths from COVID-19 last week were the lowest since March 2020, the U.N. agency reported.

Bruce66423 shares a report from the Associated Press: A rape victim whose DNA from her sexual assault case was used by San Francisco police to arrest her in an unrelated property crime on Monday filed a lawsuit against the city. During a search of a San Francisco Police Department crime lab database, the woman's DNA was tied to a burglary in late 2021. Her DNA had been collected and stored in the system as part of a 2016 domestic violence and sexual assault case, then-District Attorney Chesa Boudin said in February in a shocking revelation that raised privacy concerns. "This is government overreach of the highest order, using the most unique and personal thing we have -- our genetic code -- without our knowledge to try and connect us to crime," the woman's attorney, Adante Pointer, said in a statement.

The revelation prompted a national outcry from advocates, law enforcement, legal experts and lawmakers. Advocates said the practice could affect victims' willingness to come forward to law enforcement authorities. Federal law already prohibits the inclusion of victims' DNA in the national Combined DNA Index System. There is no corresponding law in California to prohibit local law enforcement databases from retaining victims' profiles and searching them years later for entirely different purposes.

Boudin said the report was found among hundreds of pages of evidence against a woman who had been recently charged with a felony property crime. After learning the source of the DNA evidence, Boudin dropped the felony property crime charges against the woman. The police department's crime lab stopped the practice shortly after receiving a complaint from the district attorney's office and formally changed its operating procedure to prevent the misuse of DNA collected from sexual assault victims, Police Chief Bill Scott said. Scott said at a police commission meeting in March that he had discovered 17 crime victim profiles, 11 of them from rape kits, that were matched as potential suspects using a crime victims database during unrelated investigations. Scott said he believes the only person arrested was the woman who filed the lawsuit Monday.

On Sept. 26, the Double Asteroid Redirection Test (DART) mission will slam headfirst into a small asteroid in the name of planetary defense. "[S]cientists hope that should a dangerous asteroid threaten the planet in the future, a mission like DART could avert the disaster," reports Space.com. From the report: The theory goes that if scientists ever detected an asteroid on a collision course with Earth, an impactor probe could realign the orbit of the space rock, ensuring that it crossed Earth's path when our planet was a safe distance away. But scientists don't want to be working only from theory if the situation arises. That's where DART's dramatic destruction comes into play. The spacecraft will slam into a small asteroid called Dimorphos, which like clockwork orbits a larger near-Earth asteroid called Didymos every 11 hours and 55 minutes. (Neither asteroid poses any threat to Earth, and DART won't change that.) The DART impact should adjust the orbit of Dimorphos, cutting its circuit by perhaps 10 minutes.

Scientists on Earth will be spending weeks after the impact measuring the actual change in the moonlet's orbit to compare with their predictions. The work will refine scientists' understanding of how asteroids respond to impactors and help to tune any future missions to the necessary amount of orbital change. "This isn't just a one-off event," Nancy Chabot, the DART coordination lead at the Johns Hopkins University's Applied Physics Laboratory in Maryland, which runs the mission, said during the news conference. "We want to know what happened to Dimorphos, but more important, we want to understand what that means for potentially applying this technique in the future."

While the stakes are low compared to any scenario that would motivate a real asteroid-deflecting mission, the difficulty is the same. "This is incredibly challenging," Evan Smith, the deputy mission system engineer, said during the news conference, noting that the spacecraft will only be able to see Dimorphos itself about an hour and a half before impact. "This is a par-one course, so we're going in for the hit this time." And if something doesn't go according to plan? Mission personnel are pretty confident that, as long as the spacecraft hits its target, there should be something to see. "If DART collides with Dimorphos and then you don't see any orbital period change, this would be exceptionally surprising," Chabot said. "Just the amount of momentum that DART is bringing in on its own from the weight of the spacecraft slamming into Dimorphos is enough to shift its orbit in a measurable way."

The world's chances of avoiding the worst ravages of climate breakdown are diminishing rapidly, as we enter "uncharted territory of destruction" through our failure to cut greenhouse gas emissions and take the actions needed to stave off catastrophe, leading scientists have said. From a report: Despite intensifying warnings in recent years, governments and businesses have not been changing fast enough, according to the United in Science report published on Tuesday. The consequences are already being seen in increasingly extreme weather around the world, and we are in danger of provoking "tipping points" in the climate system that will mean more rapid and in some cases irreversible shifts.

Recent flooding in Pakistan, which the country's climate minister claimed had covered a third of the country in water, is the latest example of extreme weather that is devastating swathes of the globe. The heatwave across Europe including the UK this summer, prolonged drought in China, a megadrought in the US and near-famine conditions in parts of Africa also reflect increasingly prevalent extremes of weather. The secretary general of the United Nations, Antonio Guterres, said: "There is nothing natural about the new scale of these disasters. They are the price of humanity's fossil fuel addiction. This year's United in Science report shows climate impacts heading into uncharted territory of destruction."

Ben Nowack, a 26-year old inventor and CEO of Tons of Mirrors, is trying to use satellite-mounted reflective surfaces to redirect sunlight to earthbound solar panels at night. In an interview with Motherboard, Nowack explains what inspired this idea and how he can turn his concept into reality. Here's an excerpt from the report: What was the initial idea? I had an interesting way to solve the real issue with solar power. It's this unstoppable force. Everybody's installing so many solar panels everywhere. It's really a great candidate to power humanity. But sunlight turns off, it's called nighttime. If you solve that fundamental problem, you fix solar everywhere.

Where did the idea come from? I was watching a YouTube video called The Problem with Solar Energy in Africa. It was basically saying that you need three times as many solar panels in Germany as you do in the Sahara Desert and you can't get the power from the Sahara to Germany in an easy way. I thought, what if you could beam the sunlight and then reflect it with mirrors, and put that light into laser beam vacuum tubes that zigzag around the curvature of the Earth. It could be this beam that comes in just like power companies, this tube full of infinite light. That was the initial idea. But the approach was completely economically unworkable. I was like, this is not going to compete with solar in 10 years. I should just completely give up and do something else. Then I was on a run two days later and thought what if I put that thing that turns sunlight into a beam in orbit then you don't have to build a vacuum tube anymore. And it's so much more valuable because you can shine sunlight on solar farms that already exist. Then I developed several more technologies which I know for a fact no one else is working on. That made the model even more economical.

Are these just like regular household mirrors, but fixed to a satellite? If you did that, the light would go to too many places. The sun is a certain size. It's not a point, it has a distance across. The light from one side of the sun would bounce off your mirror, and the light from the other side would also bounces off your mirror. If you used a perfectly flat mirror, every single microscopic piece would have this angle of diverging light coming from it. By the time the reflection hit Earth, you'd get a 3.6 kilometer diameter spot, which is gigantic. There are only 10 solar farms that big. So I did the math, and figured out that if I could hit a 500-meter spot instead of a 3,600-meter spot, then I'd be able to hit 44 times more solar sites per orbit.

A rocket crashed back to Earth shortly after liftoff Monday in the first launch accident for Jeff Bezos' space travel company, but the capsule carrying experiments managed to parachute to safety. From a report: No one was aboard the Blue Origin flight, which used the same kind of rocket as the one that sends paying customers to the edge of space. The rockets are now grounded pending the outcome of an investigation, the Federal Aviation Administration said.

The New Shepard rocket was barely a minute into its flight from West Texas when bright yellow flames shot out from around the single engine at the bottom. The capsule's emergency launch abort system immediately kicked in, lifting the craft off the top. Several minutes later, the capsule parachuted onto the remote desert floor. The rocket came crashing down, with no injuries or damage reported, said the FAA, which is in charge of public safety during commercial space launches and landings. Blue Origin's launch commentary went silent when the capsule catapulted off the rocket Monday morning, eventually announcing: "It appears we've experienced an anomaly with today's flight. This wasn't planned."

Doctors have told health services to prepare for a new era of cancer screening after a study found a simple blood test could spot multiple cancer types in patients before they develop clear symptoms. From a report: The Pathfinder study offered the blood test to more than 6,600 adults aged 50 and over, and detected dozens of new cases of disease. Many cancers were at an early stage and nearly three-quarters were forms not routinely screened for. It is the first time results from the Galleri test, which looks for cancer DNA in the blood, have been returned to patients and their doctors, to guide cancer investigations and any necessary treatment.

The Galleri test has been described as a potential "gamechanger" by NHS England, which is due to report results from a major trial involving 165,000 people next year. Doctors hope the test will save lives by detecting cancer early enough for surgery and treatment to be more effective, but the technology is still in development. "I think what's exciting about this new paradigm and concept is that many of these were cancers for which we do not have any standard screening," Dr Deb Schrag, a senior researcher on the study at the Memorial Sloan Kettering Cancer Center in New York, told the European Society for Medical Oncology meeting in Paris on Sunday.

An anonymous reader shares a report: The global obesity epidemic is getting worse, especially among children, with rates of obesity rising over the past decade and shifting to earlier ages. In the US, roughly 40% of today's high school students were overweight by the time they started high school. Globally, the incidence of obesity has tripled since the 1970s, with fully one billion people expected to be obese by 2030. The consequences are grave, as obesity correlates closely with high blood pressure, diabetes, heart disease and other serious health problems. Despite the magnitude of the problem, there is still no consensus on the cause, although scientists do recognize many contributing factors, including genetics, stress, viruses and changes in sleeping habits. Of course, the popularity of heavily processed foods -- high in sugar, salt and fat -- has also played a role, especially in Western nations, where people on average consume more calories per day now than 50 years ago. Even so, recent reviews of the science conclude that much of the huge rise in obesity globally over the past four decades remains unexplained.

An emerging view among scientists is that one major overlooked component in obesity is almost certainly our environment -- in particular, the pervasive presence within it of chemicals which, even at very low doses, act to disturb the normal functioning of human metabolism, upsetting the body's ability to regulate its intake and expenditure of energy. Some of these chemicals, known as "obesogens," directly boost the production of specific cell types and fatty tissues associated with obesity. Unfortunately, these chemicals are used in many of the most basic products of modern life including plastic packaging, clothes and furniture, cosmetics, food additives, herbicides and pesticides. Ten years ago the idea of chemically induced obesity was something of a fringe hypothesis, but not anymore.

"Scientists have uncovered how air pollution causes lung cancer," reports the Guardian, "in groundbreaking research that promises to rewrite our understanding of the disease."

The BBC is calling it "a discovery that completely transforms our understanding of how tumours arise." The team at the Francis Crick Institute in London showed that rather than causing damage, air pollution was waking up old damaged cells. One of the world's leading experts, Prof Charles Swanton, said the breakthrough marked a "new era". And it may now be possible to develop drugs that stop cancers forming.

The findings could explain how hundreds of cancer-causing substances act on the body. The classical view of cancer starts with a healthy cell. It acquires more and more mutations in its genetic code, or DNA, until it reaches a tipping point. Then it becomes a cancer and grows uncontrollably.... The researchers have produced evidence of a different idea. The damage is already there in our cell's DNA, picked up as we grow and age, but something needs to pull the trigger that actually makes it cancerous....

Around one in every 600,000 cells in the lungs of a 50-year-old already contains potentially cancerous mutations. These are acquired as we age but appear completely healthy until they are activated by the chemical alarm and become cancerous. Crucially, the researchers were able to stop cancers forming in mice exposed to air pollution by using a drug that blocks the alarm signal.

The results are a double breakthrough, both for understanding the impact of air pollution and the fundamentals of how we get cancer.

Long-time Slashdot reader theodp writes: A new study on the Impact of Programming on Primary Mathematics Learning (abstract only, full article $24.95 on ScienceDirect) is generating some buzz on Twitter amongst K-12 CS educator types. It concluded that:

1. Programming did not benefit mathematics learning compared to traditional activities
2. There's a negative though small effect of programming on mathematics learning
3. Mindful "high-road transfer" from programming to mathematics is not self-evident
4. Visual programming languages might distract students from mathematics activities

From the Abstract: "The aim of this study is to investigate whether a programming activity might serve as a learning vehicle for mathematics acquisition in grades four and five.... Classes were randomly assigned to the programming (with Scratch) and control conditions. Multilevel analyses indicate negative effects (effect size range 0.16 to 0.21) of the programming condition for the three mathematical notions.

"A potential explanation of these results is the difficulties in the transfer of learning from programming to mathematics."

The findings of the new study come 4+ years after preliminary results were released from the $1.5M 2015-2019 NSF-funded study Time4CS, a "partnership between Broward County Public Schools (FL), researchers at the University of Chicago, and [tech-bankrolled] Code.org," which explored whether learning CS using Code.org's CS Fundamentals curriculum may be linked to improved learning in math at the grade 3-5 level. Time4CS researchers concluded that the "quasi-experimental" study showed that "No significant differences in Florida State Assessment mathematics scores resulted between treatment and comparison groups."

China is claiming it discovered a new lunar mineral in moon samples it retrieved in 2020. From the South China Morning Post: The mineral, called Changesite-(Y), was found in rock and dust samples retrieved from the moon by China's Chang'e-5 mission, the nation's first mission to return a lunar sample, which launched in 2020.

A research team from the Beijing Research Institute of Uranium Geology, a subsidiary of the China National Nuclear Corporation (CNNC), isolated a single crystalline particle of the material from more than 140,000 lunar particles using hi-tech processes, including X-ray diffraction, according to Wang Xuejun, a party official with the CNNC. The particle was about 10 microns in diameter, or about one-tenth of a human hair, Wang told a press conference on Friday....

Meanwhile, Wang added that the research team had for the first time measured the concentration of a future fusion energy source, in the lunar sample. "It provides fundamental scientific data for future assessment of helium-3 in lunar samples and their exploration," Wang said.
If confirmed, it would provide "more basic scientific data for the evaluation and development of lunar resources," according to an executive with the China Atomic Energy Authority, while also deepening mankind's knowledge of the solar system. (It would be the sixth new mineral discovered on the moon.)

Speaking at a press conference, he told the audience that China "has also become the third country to retrieve lunar samples and discover new lunar minerals after the U.S. and Russia." The article points out that China hopes to land another sample-collecting probe to the moon "around 2024," and that a senior lunar program designer said China "could" land astronauts on the moon by 2030.

SiFive is the first company to produce a chip implementing the RISC-V ISA.

They've now been selected to provide the core CPU for NASA's next generation High-Performance Spaceflight Computing processor (or HSPC), according to a SiFive announcement: HPSC is expected to be used in virtually every future space mission, from planetary exploration to lunar and Mars surface missions.

HPSC will utilize an 8-core, SiFive® Intelligence X280 RISC-V vector core, as well as four additional SiFive RISC-V cores, to deliver 100x the computational capability of today's space computers. This massive increase in computing performance will help usher in new possibilities for a variety of mission elements such as autonomous rovers, vision processing, space flight, guidance systems, communications, and other applications....

The SiFive X280 is a multi-core capable RISC-V processor with vector extensions and SiFive Intelligence Extensions and is optimized for AI/ML compute at the edge. The X280 is ideal for applications requiring high-throughput, single-thread performance while under significant power constraints. The X280 has demonstrated a 100x increase in compute capabilities compared to today's space computers..

In scientific and space workloads, the X280 provides several orders of magnitude improvement compared to competitive CPU solutions.
A business development executive at SiFive says their X280 core "demonstrates orders of magnitude performance gains over competing processor technology," adding that the company's IP "allows NASA to take advantage of the support, flexibility, and long-term viability of the fast-growing global RISC-V ecosystem.

"We've always said that with SiFive the future has no limits, and we're excited to see the impact of our innovations extend well beyond our planet."

And their announcement stresses that open hardware is a win for everybody: The open and collaborative nature of RISC-V will allow the broad academic and scientific software development community to contribute and develop scientific applications and algorithms, as well optimizing the many math functions, filters, transforms, neural net libraries, and other software libraries, as part of a robust and long-term software ecosystem.

Slashdot reader storagedude writes: Nearly a quarter of healthcare organizations hit by ransomware attacks experienced an increase in patient mortality, according to a new study from Ponemon Institute and Proofpoint.

The report, "Cyber Insecurity in Healthcare: The Cost and Impact on Patient Safety and Care," surveyed 641 healthcare IT and security practitioners and found that the most common consequences of cyberattacks are delayed procedures and tests, resulting in poor patient outcomes for 57% of the healthcare providers, followed by increased complications from medical procedures. The type of attack most likely to have a negative impact on patient care is ransomware, leading to procedure or test delays in 64% of the organizations and longer patient stays for 59% of them.

The Ponemon report depends on the accuracy of self-reporting and thus doesn't have the weight of, say, an epidemiological study that looks at hospital mortality baseline data before and after an attack, but the data is similar to what Ponemon has found in the past and there have been a number of reports of patient deaths and other complications from ransomware attacks.

The new report found that 89% of the surveyed organizations have experienced an average of 43 attacks in the past year. The most common types of attacks were cloud compromise, ransomware, supply chain, and business email compromise (BEC)/spoofing/phishing.

The Internet of Medical Things (IoMT) is a top concern for survey participants. Healthcare organizations have an average of more than 26,000 network-connected devices, yet only 51% of the surveyed organizations include them in their cybersecurity strategy.

Healthcare organizations are better at cloud security, with 63% taking steps to prepare for and respond to cloud compromise attacks, and 62% have taken steps to prevent and respond to ransomware — but that still leaves nearly 40% of healthcare organizations more vulnerable than they should be.

Preparedness is even worse for supply chain attacks and BEC, with only 44% and 48% having a documented response to those attacks, respectively.

The high costs of healthcare cyberattacks — an average of $4.4 million — mean that healthcare cybersecurity tools likely have a high ROI, even though roughly half of the survey respondents say they lack sufficient staffing and in-house expertise.

America's Department of Agriculture and NASA recently announced the Artemis Moon Trees Program. After the first launch of its SLS super-heavy-lift launch vehicle, "the seeds carried on Artemis I will be grown into seedlings by the Forest Service and distributed to locations across the U.S."

But it's just part of a larger initiative. The U.S. government announced Friday that it's working with "a new coalition of space companies that will focus on increasing the space industry's capacity to meet the rising demand for the skilled technical workforce" — partly by inspiring and educating the next generation. This coalition includes Lockheed Martin, Northrop Grumman, Boeing, Blue Origin, Jacobs, L3Harris, Planet Labs PBC, Rocket Lab, Sierra Space, Space X and Virgin Orbit.

Long-time Slashdot reader theodp writes: Yesterday at the second convening of America's National Space Council, Vice President Kamala Harris announced "new commitments from the U.S. government, private sector companies, education and training providers, and philanthropic organizations to support space-related STEM initiatives to inspire, prepare, and employ the next generation of the space workforce..." according to a statement from the White House, "to address the challenges of today and prepare for the discoveries of tomorrow...."

Among those anchoring the Administration's efforts to increase the space industry's capacity to meet the rising demand for the skilled technical workforce is Amazon founder Jeff Bezos' space tourism company Blue Origin, which will be joined by industry partner Amazon to inspire youth to pursue space STEM careers. "Blue Origin's Club for the Future," the White House explains, "is launching Space Days to engage millions of students, teachers and school administrators in the excitement of space and space careers." Club for the Future, as reported earlier on Slashdot, is the Blue Origin founded-and-funded tax-exempt foundation that received the $28 million proceeds of a single auctioned ticket to accompany Bezos on Blue Origin's maiden 11-minute space tourism flight in June 2021. The nonprofit's mission is "to inspire future generations to pursue careers in STEM and to help invent the future of life in space."

The White House also announced that Amazon and Bezos-funded nonprofit Code.org "will highlight connections between computer science and space exploration in the 2022 Hour of Code. Students will have the opportunity to explore and develop coding skills through engaging, space-themed tutorials and create shareable projects. Through a collaboration with NASA, the U.S. Space Force, America's Department of Energy, and the U.S. Geological Survey, students will also learn about different careers and pathways for space careers in these agencies. Code.org reaches approximately 15 million students annually." Amazon reported in 2018 on its efforts to accelerate K-12 CS education in the U.S. with Code.org to "support the much-needed pipeline for workers who are well versed in computer science."
The coalition's other efforts include three pilot programs collaborating with community colleges, unions and others "to demonstrate a replicable and scalable approach to attracting, training and creating employment opportunities." Federal agencies and the Smithsonian Institute also launched a new web site with free space-related resources for K-12 educators which also promotes career awareness.

And NASA also released an educator resources hub that includes a LEGO Build to Launch Series — plus $4 million in educational grants.
