Asteroid Mining Startup Loses Its Spacecraft Somewhere Beyond the Moon:

A privately built spacecraft is tumbling aimlessly in deep space, with little hope of being able to contact its home planet. Odin is around 270,000 miles (434,522 kilometers) away from Earth, on a silent journey that's going nowhere fast.

California-based startup AstroForge launched its Odin spacecraft on February 26 on a SpaceX Falcon 9 rocket. The probe was headed toward a small asteroid to scan it for valuable metals, in service of the company's ambitious goal of mining asteroids for profit. AstroForge was also hoping to become the first company to launch a commercial mission to deep space with its in-house spacecraft, a dream that fell apart shortly after launch.

After Odin separated from the rocket, the company's primary ground station in Australia suffered major technical issues due to a power amplifier breaking, delaying AstroForge's first planned attempt to contact the spacecraft, the company revealed in an update on Thursday. The mission went downhill from there, as several attempts to communicate with Odin failed and the spacecraft's whereabouts were unknown. "I think we all know the hope is fading as we continue the mission," AstroForge founder Matt Gialich said in a video update shared on X.

AstroForge is working on developing technologies for mining precious metals from asteroids millions of miles away. The company launched its first mission in April 2023 to demonstrate its ability to refine asteroid material in orbit. Its initial task also did not go as planned, as the company struggled to communicate with its satellite.

For its second mission, AstroForge opted to build its spacecraft in-house to avoid some of the problems encountered during its first mission, Gialich told Gizmodo in an interview last year. AstroForge built the $3.5 million spacecraft in less than ten months. "We know how to build these craft. These have been built before. They just cost a billion fucking dollars. How do we do it for a fraction of the cost?" Gialich is quoted as saying in AstroForge's recent update. "At the end of the day, like, you got to fucking show up and take a shot, right? You have to try."

Amid a Growing Measles Outbreak, Doctors Worry RFK is Sending the Wrong Message

Amid a growing measles outbreak, doctors worry RFK is sending the wrong message:

[...] Two people have now died in the growing measles outbreak in west Texas and New Mexico.

New Mexico Health officials on Thursday confirmed the death of an unvaccinated adult who tested positive for measles. The first death was a school-age child in Gaines County, Texas last week.

News of a second death comes as infectious disease doctors worry that the federal government's messaging about the outbreak is putting more emphasis on treatments like vitamin A than on vaccination, even as misinformation about some of these treatments is spreading online.

Those concerns come in the wake of recent comments made by Health and Human Services Secretary Robert F. Kennedy Jr. Kennedy addressed the growing measles outbreak in an editorial for FOX News published on Sunday, also posted on the HHS website.

While mentioning the value of vaccination for community immunity, Kennedy said "the decision to vaccinate is a personal one." He emphasized treatment for measles, saying that vitamin A can "dramatically" reduce deaths from the disease. In an interview with FOX News Tuesday, he said Texas doctors are giving steroids and cod liver oil to their measles patients and "getting very, very, good results."

In his editorial, he said good nutrition is "a best defense against most chronic and infectious illnesses." That emphasis on nutrition and vitamin A to treat measles is concerning some infectious disease doctors.

"Mentions of cod liver oil and vitamins [are] just distracting people away from what the single message should be, which is to increase the vaccination rate, " said Dr. Amesh Adalja, an infectious disease physician and senior scholar with the Johns Hopkins Center for Health Security.

While vitamin A can play a role in preventing severe disease, discussion of vitamins, "doesn't replace the fact that measles is a preventable disease. And really, the way to deal with a measles outbreak is to vaccinate people against measles," says Dr. Adam Ratner, a member of the infectious disease committee of the American Academy of Pediatrics.

Kennedy did acknowledge that measles is highly contagious and that it poses health risks, especially to people who are not vaccinated. He said vaccines not only protect individual children from measles, but also protect people who can't be vaccinated. But he didn't strongly encourage people to get their children vaccinated — which is usually a key part of the public health response during an outbreak.

In 2019, when a measles outbreak was raging in the U.S., then health secretary Alex Azar came out with a statement strongly supporting vaccination and warning of the risks of under-vaccination.

Engineers and executives at the so-called Department of Government Efficiency are drawing healthy taxpayer-funded salaries—sometimes from the very agencies they are cutting.

[...] Jeremy Lewin, one of the DOGE employees tasked with dismantling USAID, who has also played a role in DOGE's incursions into the National Institutes of Health and the Consumer Financial Protection Bureau, is listed as making just over $167,000 annually, WIRED has confirmed. Lewin is assigned to the Office of the Administrator within the General Services Administration.

Kyle Schutt, a software engineer at the Cybersecurity and Infrastructure Security Agency, is listed as drawing a salary of $195,200 through GSA, where he is assigned to the Office of the Deputy Administrator. That is the maximum amount that any "General Schedule" federal employee can make annually, including bonuses. "You cannot be offered more under any circumstances," the GSA compensation and benefits website reads.

Nate Cavanaugh, a 28-year-old tech entrepreneur who has taken a visible internal role interviewing GSA employees as part of DOGE's work at the agency, is listed as being paid just over $120,500 per year. According to DOGE's official website, the average GSA employee makes $128,565 and has worked at the agency for 13 years.

When Elon Musk started recruiting for DOGE in November, he described the work as "tedious" and noted that "compensation is zero." WIRED previously reported that the DOGE recruitment effort relied in part on a team of engineers associated with Peter Thiel and was carried out on platforms like Discord.

Since Trump took office in January, DOGE has overseen aggressive layoffs within the GSA, including the recent elimination of 18F, the agency's unit dedicated to technology efficiency. It also developed a plan to sell off more than 500 government buildings.

Although Musk has described DOGE as "maximum transparent," it has not made its spending or salary ranges publicly available. Funding for DOGE had grown to around $40 million as of February 20, according to a recent ProPublica report. The White House did not respond to questions about the salary ranges for DOGE employees or how the budget is allocated to pay them.

Arthur T Knackerbracket has processed the following story:

Alphabet has announced a new development for Taara's technology that could lead to low-cost, high-speed internet connectivity, even in far-flung locations. Taara's general manager, Mahesh Krishnaswamy, has introduced the Taara chip, a silicon photonic chip that uses light to transmit high-speed data through the air. The Taara chip is abut the size of a fingernail, far smaller than the technology the Alphabet division has been using. Taara Lightbridge, which is what its first-generation technology is called, is the size of a traffic light and uses a system of mirrors and sensors to physically steer light to where it needs to go. The new chip uses software instead.

Taara is a project under X, Alphabet's moonshot factory. The high speed wireless optical link technology underpinning the project was originally developed for X's Project Loon internet broadcasting balloons. Alphabet pulled the plug on Loon in 2021 and focused on Taara instead, using its technology to beam broadband across the Congo River and the streets of Nairobi. Even years before Loon shut down, Alphabet's X was already toying with the idea of using light to beam internet and tested the technology in India.

Taara's technology works by using a "very narrow, invisible light beam to transmit data at speeds as high as 20 gigabits per second, up to distances of 20 kilometers (12.1 miles)." It's like traditional fiber, in the sense that it uses light to carry data, except that light doesn't travel through cables. Instead, Taara's hardware emits beams of light. The beams from two units must be aligned with each other to be able to form a secure link that can transmit data, which is why Lightbridge was fitted with the parts needed to be able to physically steer the light. Taara's new chip doesn't need those components: It contains hundreds of tiny light emitters controlled by software with automatic steering

Krishnaswamy said Taara's light-beaming units will only take days to install instead of the months or years it can take to lay fiber. During tests in the lab, the Taara team was able to transmit data at speeds of 10 Gbps over a distance of one kilometer (0.62 miles) using two of the new chips. They're now looking to improve the chip's capacity and range by creating an "iteration with thousands of [light] emitters." The team expects the chip to be available in 2026.

Hugging Face's chief science officer worries AI is becoming 'yes-men on servers':

AI company founders have a reputation for making bold claims about the technology's potential to reshape fields, particularly the sciences. But Thomas Wolf, Hugging Face's co-founder and chief science officer, has a more measured take.

In an essay published to X on Thursday, Wolf said that he feared AI becoming "yes-men on servers" absent a breakthrough in AI research. He elaborated that current AI development paradigms won't yield AI capable of outside-the-box, creative problem-solving — the kind of problem-solving that wins Nobel Prizes.

"The main mistake people usually make is thinking [people like] Newton or Einstein were just scaled-up good students, that a genius comes to life when you linearly extrapolate a top-10% student," Wolf wrote. "To create an Einstein in a data center, we don't just need a system that knows all the answers, but rather one that can ask questions nobody else has thought of or dared to ask."

Wolf's assertions stand in contrast to those from OpenAI CEO Sam Altman, who in an essay earlier this year said that "superintelligent" AI could "massively accelerate scientific discovery." Similarly, Anthropic CEO Dario Amodei has predicted AI could help formulate cures for most types of cancer.

Wolf's problem with AI today — and where he thinks the technology is heading — is that it doesn't generate any new knowledge by connecting previously unrelated facts. Even with most of the internet at its disposal, AI as we currently understand it mostly fills in the gaps between what humans already know, Wolf said.

Some AI experts, including ex-Google engineer François Chollet, have expressed similar views, arguing that while AI might be capable of memorizing reasoning patterns, it's unlikely it can generate "new reasoning" based on novel situations.

Wolf thinks that AI labs are building what are essentially "very obedient students" — not scientific revolutionaries in any sense of the phrase. AI today isn't incentivized to question and propose ideas that potentially go against its training data, he said, limiting it to answering known questions.

https://arstechnica.com/ai/2025/03/users-report-emotional-bonds-with-startlingly-realistic-ai-voice-demo/

In late 2013, the Spike Jonze film Her imagined a future where people would form emotional connections with AI voice assistants. Nearly 12 years later, that fictional premise has veered closer to reality with the release of a new conversational voice model from AI startup Sesame that has left many users both fascinated and unnerved.

"I tried the demo, and it was genuinely startling how human it felt," wrote one Hacker News user who tested the system.
[...]
In late February, Sesame released a demo for the company's new Conversational Speech Model (CSM) that appears to cross over what many consider the "uncanny valley" of AI-generated speech
[...]
"At Sesame, our goal is to achieve 'voice presence'—the magical quality that makes spoken interactions feel real, understood, and valued," writes the company in a blog post.
[...]
Sometimes the model tries too hard to sound like a real human. In one demo posted online by a Reddit user called MetaKnowing, the AI model talks about craving "peanut butter and pickle sandwiches."
[...]
"I've been into AI since I was a child, but this is the first time I've experienced something that made me definitively feel like we had arrived," wrote one Reddit user.
[...]
Many other Reddit threads express similar feelings of surprise, with commenters saying it's "jaw-dropping" or "mind-blowing."
[...]
Mark Hachman, a senior editor at PCWorld, wrote about being deeply unsettled by his interaction with the Sesame voice AI. "Fifteen minutes after 'hanging up' with Sesame's new 'lifelike' AI, and I'm still freaked out," Hachman reported.
[...]
Others have compared Sesame's voice model to OpenAI's Advanced Voice Mode for ChatGPT, saying that Sesame's CSM features more realistic voices, and others are pleased that the model in the demo will roleplay angry characters, which ChatGPT refuses to do.
[...]
Under the hood, Sesame's CSM achieves its realism by using two AI models working together (a backbone and a decoder) based on Meta's Llama architecture that processes interleaved text and audio. Sesame trained three AI model sizes, with the largest using 8.3 billion parameters (an 8 billion backbone model plus a 300 million parameter decoder) on approximately 1 million hours of primarily English audio.

Apple appeal to Investigatory Powers Tribunal may be the first case of its type:

Apple reportedly filed an appeal in hopes of overturning a secret UK order requiring it to create a backdoor for government security officials to access encrypted data.

"The iPhone maker has made its appeal to the Investigatory Powers Tribunal, an independent judicial body that examines complaints against the UK security services, according to people familiar with the matter," the Financial Times reported today. The case "is believed to be the first time that provisions in the 2016 Investigatory Powers Act allowing UK authorities to break encryption have been tested before the court," the article said.

A Washington Post report last month said UK security officials "demanded that Apple create a backdoor allowing them to retrieve all the content any Apple user worldwide has uploaded to the cloud," including "blanket capability to view fully encrypted material."

Apple has publicly criticized the law, warning last year that the UK government is claiming power to demand access to the data of users in any country, not just the UK.

Apple responded to the recent order by pulling its Advanced Data Protection (ADP) service from the UK. The optional level of encryption for iCloud prevents even Apple from seeing user data. "Apple can no longer offer Advanced Data Protection (ADP) in the United Kingdom to new users and current UK users will eventually need to disable this security feature," Apple said last month.

"As we have said many times before, we have never built a backdoor or master key to any of our products or services and we never will," Apple also said.

Backdoors demanded by governments have alarmed security and privacy advocates, who say the special access would be exploited by criminal hackers and other governments. Bad actors typically need to rely on vulnerabilities that aren't intentionally introduced and are patched when discovered. Creating backdoors for government access would necessarily involve tech firms making their products and services less secure.

The order being appealed by Apple is a Technical Capability Notice issued by the UK Home Office under the 2016 law, which is nicknamed the Snoopers' Charter and forbids unauthorized disclosure of the existence or contents of a warrant issued under the act.

[...] Under the law, Investigatory Powers Tribunal decisions can be challenged in an appellate court.

Tests reveal a lack of microbial diversity on board. That's been linked to health issues in other settings:

With air filters and weekly wipe-downs and vacuuming, NASA goes to great lengths to keep the International Space Station clean so that astronauts stay healthy. But astronauts still often experience health problems like immune dysfunction, skin rashes and other inflammatory conditions. One reason may be because the ISS might be too clean, a new study suggests.

Microbes, tiny living organisms like bacteria and viruses, play an important role in human health. But samples of surfaces in the ISS reflect a striking lack of microbial diversity, Rodolfo Salido Benítez, a bioengineer at University of California, San Diego, and colleagues report February 27 in Cell.

[...] Inside and outside the body, microbes compete for resources and space, so maintaining a diverse set keeps any one of them from taking over and causing an health problems. Low microbial diversity in hospitals, for example, leads to a higher risk of infection. Even the microbes in your house can affect your health. One study found that Amish communities have a lower risk of asthma than other communities with similar lifestyles because their household dust contains microbes from farm animals.

[...] Maintaining a healthy diversity of microbes in confined spaces will be a growing concern as astronauts spend more time in space and new missions begin. Scientists will need to test new ways of adding more "good germs" to the mix, like bringing animals aboard or stocking the ISS pantry with fermented foods, says Pieter Dorrestein, a chemical biologist at UC San Diego.

"The reality is that we're going to inhabit space at some point, so this work will give us the first insight in terms of the things that we need to add and remove," Dorrestein says. "The most important message that we can pass on is how important is to not only look at what's present, but also what's absent."

Arthur T Knackerbracket has processed the following story:

Climate experts have long believed that a volcanic supereruption—a mind-bendingly powerful explosion capable of altering Earth’s atmosphere—could wipe out a significant portion of life. But a new survey of geological records suggests the aftermath wouldn’t be quite as apocalyptic. It would still be bad—just not end-of-the-world-as-we-know-it bad.

This refreshing burst of optimism comes courtesy of a group of University of St. Andrews environmental scientists who were examining ice cores pulled from Greenland and Antarctica, as well as sediment cores from near the equator in the Pacific.

The cores contained tiny specks of ash, embedded in layers connected to the time period of the Los Chocoyos supereruption, which occurred in what is now known as Guatemala’s Atitlán caldera. While the Smithsonian’s Global Volcanism Project dates the eruption to 84,000 years ago, St. Andrews geologists claim to have more accurately dated the ash to 79,500 years ago.

Just for a frame of reference, the most powerful eruption in recent memory occurred on June 12, 1991, when the Philippines’ Mount Pinatubo finally blew, after months of earthquakes and magma slowly seeping to the top. The resulting ash cloud was 22 miles (35 kilometers) high, and 20 million tons of sulfur was emitted into the atmosphere, leading to a 1 degree F (0.5 C) drop in global temperatures from 1991 to 1993, according to the U.S. Geological Survey. So much rock and magma was ejected that the mountain’s shape was irrevocably altered, leaving behind a depression called a caldera that was 1.6 miles (2.5 kilometers) across. Because the signs of eruption were caught early, thousands of people were able to leave the area beforehand and commercial air travel steered clear. Even so, the force was so huge, $100 million of damage was caused to jets flying hundreds of kilometers away.

That eruption measured only a 6 on the Volcanic Explosivity Index. Los Chocoyos comes in at an 8, the lowest score required to register as a supereruption, which would still make it 100 times more powerful than Pinatubo.

New research published in Chemosphere reveals an alarming reality: everyday kitchen utensils may quietly harm your well-being. The research reveals the extent to which some cooking tools, particularly black plastic ones, contaminate food with deadly toxins while we cook:

Black plastic kitchenware is a serious problem. Most contain harmful chemicals like flame retardants, colorants, and other additives that can migrate into food during cooking. The study cites black non-stick cookware, plastic cutting boards, and plastic utensils as particular causes of chemical contamination.

Even though plastic kitchenware is convenient, cheap, and easy to clean, these benefits are paid for with a potential cost to your health. The longevity and ease of cleaning that sell the products to consumers cannot be worth the potential health risks they provide.

Scientists are most concerned with long-term exposure through regular food preparation.

Black spatulas, plastic forks and knives, and certain pans release toxic chemicals such as decabromodiphenyl ether (decaBDE), a flame retardant found in household goods. The chemical has been linked to thyroid and hormone disruption, cancer risks, and developmental issues in children. What makes these pollutants sneaky is that they are invisible – there is no way for consumers to know they are there.

Even more alarming, many of those toxic chemicals are recycled from electronics. Manufacturers put flame retardants in kitchenware in the guise of making kitchens safer against fire, but in doing so, they cause significant health risks that can outweigh any safety advantage.

[...] To minimize exposure to these poisons, substitute offending cookware with safer options that can be simply incorporated into your daily cooking routine:

• Replace plastic cutlery with old-school metal silverware, which will not leach chemicals into food and offers improved durability
• Substitute non-stick pans with stainless steel or cast iron cookware. Though stainless steel may take a bit longer to preheat, it offers a safer cooking surface free of potentially toxic substances
• Substitute plastic cutting boards with tempered glass cutting boards, offering a non-porous, chemical-free surface that is resistant to bacterial contamination and doesn't release microplastics when foods are being prepared.
• As an alternative to glass, opt for solid wood cutting boards without glue-based adhesives if glass seems impractical. Choose boards constructed from a single piece of wood rather than composite materials that can contain chemical adhesives. Keep in mind that these natural alternatives must be hand-washed rather than dishwasher-cleaned

https://www.raspberrypi.com/news/how-we-added-interlaced-video-to-raspberry-pi-5/

The very first Raspberry Pi had a composite video output, and all models with a 40-pin header have a display parallel interface (DPI) output. With some external components, DPI can be converted to VGA or RGB/SCART video. Those analogue interfaces are still in demand for retro media and gaming.

Raspberry Pi 5 was a big step up in processing power, but unlike previous models, its DPI block didn't support interlaced video (which isn't really part of the DPI standard), so it couldn't send full-resolution RGB to a CRT television. Until now.

To generate interlaced video, we had to do three things:

1. Get DPI to emit fields (even or odd lines of a frame-buffer) instead of frames
2. Time those signals so they will be in the proper arrangement for interlace
3. Generate appropriate sync pulses

The first part is easy. By changing an address and doubling the 'stride' between lines, we can arrange for DPI to read and display just the even or odd lines of a frame-buffer.

The second problem is solved by hacking the DPI peripheral. If we time it just right, we can change its configuration on the fly, so that every second frame — every second field, I should say — gets one extra blank line at the end.

The third problem is harder. RP1's DPI has no way to make vertical sync pulses start midway through a line.

Our RP1 chip has a Programmable Input/Output (PIO) block. We recently added PIO support to our version of the Linux kernel

Here, PIO snoops on DPI's horizontal sync (HSync) and data enable (DE) pins to generate vertical sync (VSync). Two of PIO's four state machines (SMs) are used: one SM serves as a timer, generating an 'interrupt' at the start and middle of each line. The other SM finds the start of the vertical blanking interval (the first line without DE), then counts half-lines to work out when to start and end the VSync pulse. Finally, it samples DE again to detect the extra blank line, to ensure it has the correct field-phase for next time.

The sync fixup consumes most of RP1's PIO instruction memory, so PIO can't be used for other cool things at the same time as generating interlaced DPI.

If you have a Raspberry Pi 5, a VGA666 HAT, and a VGA monitor that can run at 50Hz TV rates, you could test it by adding this to config.txt:

*SPOILER* (click to show) *SPOILER* (click to hide)

dtoverlay=vc4-kms-dpi-generic
dtparam=clock-frequency=13500000
dtparam=hactive=720,hfp=12,hsync=64,hbp=68
dtparam=vactive=576,vfp=5,vsync=5,vbp=39
dtparam=vsync-invert,hsync-invert
dtparam=interlaced

Composite sync too

VGA cables have separate wires for horizontal and vertical sync, but TVs combine everything in one signal (composite video). A halfway house, used in SCART, is 'composite sync', which multiplexes the two sync signals but keeps them separate from RGB.

RP1's DPI can't generate VSync in interlaced modes. Instead, we get it to output a 'helper signal' that alternates between 1-line and 2-line pulses. PIO snoops on HSync and the helper signal to synthesize CSync.

BP shuns renewables in return to oil and gas:

BP has announcedit will cut its renewable energy investments and instead focus on increasing oil and gas production.

The energy giant revealed the shift in strategy on Wednesday following pressure from some investors unhappy its profits and share price have been lower than its rivals.

BP said it would increase its investments in oil and gas by about 20% to $10bn (£7.9bn) a year, while decreasing previously planned funding for renewables by more than $5bn (£3.9bn).

The move comes as rivals Shell and Norwegian company Equinor have also scaled back plans to invest in green energy and US President Donald Trump's "drill baby drill" comments have encouraged investment in fossil fuels.

Murray Auchincloss, BP's chief executive, said the energy giant had gone "too far, too fast" in the transition away from fossil fuels, and that its faith in green energy was "misplaced".

He said BP would be "very selective" in investing in businesses working on the energy transition to renewables going forward, with funding reduced tobetween $1.5bn and $2bn per year.

He said this was part of a strategy "reset" by the company to focus on boosting returns for shareholders.

Helge Lund, chair of BP, added that the new direction of the firm had "cash flow growth" at its heart.

Shares in the company climbed before Tuesday's announcement but fell shortly after.

The FCC runs an $8 billion federal subsidy program to help bring phone and broadband services to lower income homes and schools called the Universal Service Fund. The program was historically a bipartisan thing, until the extremist Trump administration came to town.

Driven by a fake right wing consumer group called “Consumers’ Research,” the Trumplican-stacked Fifth Circuit court of appeals recently took the radical step of ruling the entire program unconstitutional. The ruling, which ignored past Fifth Circuit and Supreme Court precedent, effectively declared the USF an unconstitutional, illegal tax, something seven court dissenters said was a preposterous leap.

Now the Supreme Court has stated they’ll hear the case, which will ultimately determine whether federal efforts to expand broadband access to poor, rural neglected communities is effectively illegal or not.

Not too surprisingly, 15 MAGA loyal Attorneys General, apparently with nothing better to do, have thrown their support behind the effort to effectively make helping poor people afford broadband illegal:

"The world's first "biological computer" that fuses human brain cells with silicon hardware to form fluid neural networks has been commercially launched, ushering in a new age of AI technology. The CL1, from Australian company Cortical Labs, offers a whole new kind of computing intelligence – one that's more dynamic, sustainable and energy efficient than any AI that currently exists – and we will start to see its potential when it's in users' hands in the coming months.

Known as a Synthetic Biological Intelligence (SBI), Cortical's CL1 system was officially launched in Barcelona on March 2, 2025, and is expected to be a game-changer for science and medical research. The human-cell neural networks that form on the silicon "chip" are essentially an ever-evolving organic computer, and the engineers behind it say it learns so quickly and flexibly that it completely outpaces the silicon-based AI chips used to train existing large language models (LLMs) like ChatGPT."

[...] Inside the CL1 system, lab-grown neurons are placed on a planar electrode array – or, as Kagan explained, "basically just metal and glass." Here, 59 electrodes form the basis of a more stable network, offering the user a high degree of control in activating the neural network. This SBI "brain" is then placed in a rectangular life-support unit, which is then connected to a software-based system to be operated in real time.

"A simple way to describe it would be like a body in a box, but it has filtration for waves, it has where the media is stored, it has pumps to keep everything circulating, gas mixing, and of course temperature control," Kagan explained.

In the lab, Cortical is assembling these units to construct a first-of-its-kind biological neural network server stack, housing 30 individual units that each contain the cells on their electrode array, which is expected to go online in the coming months.
