We've spent decades scratching the surface of Mars trying to uncover life there. But we've been searching a barren wasteland bombarded by radiation and bathed in toxic perchlorates. The entire time, it's likely that it's been too hostile to harbor extant life. So if we want a better shot at finding currently living life on Mars, we need to go underground. That is exactly the purpose of Orpheus, a proposed Mars vertical takeoff and landing (VTOL) hopper mission put forth in a paper [PDF] presented by Connor Bunn and Pascal Lee of the SETI Institute at the 57th Lunar and Planetary Science Conference (LPSC).

In what might be the best naming reference for a space mission ever, Orpheus is named after the Greek hero who tamed the three-headed hound Cerberus to gain access to the Underworld. The actual mission aims to explore the deep volcanic fissures, pits, and cave vents of a region of Mars known as Cerberus Fossae. While there, it plans to unlock some of Mars's origin story, as well as search for biosignatures that indicate the presence of extant life.

Finding something on another planet that is still alive is the single highest priority of the field of astrobiology. It's the only way we can perform the protein and genetic analyses needed to prove that the life we found didn't just hitch a ride from Earth on a meteorite billions of years ago. But so far, we've come up with nothing.

Cerberus Fossae, however, is a good place to look for it. It's part of Elysium Planitia, and boasts some of the youngest known volcanoes and lava flows on the entire Red Planet. Young volcanoes are thought of as potential astrobiological gold mines—they hold better-preserved erupted materials, and, crucially, fresher biosignatures. Not to mention that life on Earth itself might very well have started next to volcanic fissures in the deep ocean.

In April 2026, Google's IPv6 statistics revealed a significant milestone: IPv6 traffic has crossed the 50% mark globally, with native IPv6 adoption reaching 45.54% and total IPv6 (including 6to4/Teredo) at 45.54% as of April 13, 2026. While this represents genuine progress in the decades-long transition from IPv4 to IPv6, the journey has been remarkably slow, and the plateau at 50% raises important questions about the future of internet infrastructure.

IPv6 was designed as the successor to IPv4, addressing the fundamental limitation of IPv4's 32-bit address space, which can only support approximately 4.3 billion unique addresses. With the explosive growth of the internet, mobile devices, IoT sensors, and cloud computing, IPv4 address exhaustion became an inevitable crisis. IPv6's 128-bit address space provides 340 undecillion addresses — enough for virtually unlimited growth.

Despite being standardized in 1998, IPv6 adoption has been glacially slow. The technology has been available for nearly three decades, yet we're only now crossing the 50% threshold. This sluggish adoption reveals fundamental challenges in technology transitions at internet scale.

Several factors have contributed to IPv6's slow adoption:

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

1. The IPv4 Abundance Problem: Unlike developing regions that face IPv4 scarcity, the United States and Europe have historically had abundant IPv4 address space. This reduced the urgency for transition. Large incumbent cloud providers like AWS, Azure, and Google have accumulated vast IPv4 address pools, creating a perverse incentive to maintain IPv4 as the default. These companies benefit from IPv4scarcity — they can charge premium prices for IPv4 addresses while offering IPv6 for free.
2. Enterprise Inertia: Large organizations have invested heavily in IPv4-based infrastructure. Transitioning to IPv6 requires updating network equipment, retraining staff, and potentially rewriting applications. The business case for this investment is weak when IPv4 continues to function, even if inefficiently through Carrier-Grade NAT (CGNAT).
3. The GitHub Problem: A striking example of this inertia is GitHub's continued lack of IPv6 support. Despite being owned by Microsoft — a company that has been working toward IPv6-only internal networks for over a decade — GitHub.com remains IPv4-only. This sends a powerful signal to the industry that IPv6 isn't critical, even for a platform essential to modern software development.
4. Complexity and Operational Burden: IPv6 introduces operational complexity that many organizations find daunting. Unlike IPv4's straightforward NAT model, IPv6 requires understanding concepts like:
1. Multiple addresses per host (global unicast, link-local, ULA)
2. Stateless address autoconfiguration (SLAAC)
3. Stateful DHCPv6 (which Android doesn't support)
4. IPv6 extension headers and their security implications
5. Rate limiting and IP-based access controls at scale

These complexities mean that IPv6 support isn't just a checkbox — it requires genuine expertise.

5. The Chicken-and-Egg Problem: Users don't demand IPv6 because most websites don't require it. Websites don't implement IPv6 because most users don't need it. This circular dependency has perpetuated IPv4's dominance despite its technical limitations.

Google to punish sites that trap people in with back button tricks:

Google says it is expanding its policies to crack down on websites which trap users with "back button hijacking".

Back button hijacking is when a website interferes with a browser so the back button no longer takes users to the previous page, instead often keeping them on the site or presenting unsolicited ads.

In a blog post the tech giant behind the Chrome browser said it had seen a "rise of this type of behaviour" which had led it to act.

From 15 June the tactic will be deemed a "malicious practice", meaning sites which continue to adopt it may be down-ranked or even removed from Google Search results.

"Back button hijacking interferes with the browser's functionality, breaks the expected user journey, and results in user frustration," Google said in its post .

"People report feeling manipulated and eventually less willing to visit unfamiliar sites," it added.

Examples of practices it would clamp down on included sites using any technique which inserted "manipulative" pages into a user's browser history that stopped them from returning to the previous page.

Adam Thompson, director of digital at BCS, the Chartered Institute for IT, told the BBC: "Practices like back button hijacking undermine the basic user experience and break the expectations people have of how the web should work, so it's understandable that Google views this as a harmful behaviour and [is] taking action."

Google advised site owners which did not want to face the new penalties to ensure they did not do "anything to interfere with a user's ability to navigate their browser history", urging them to "thoroughly review their technical implementation".

It added sites which were penalised but then fixed the issue could submit a request to Google to have the demotion reconsidered.

There has been considerable debate among physicists over the last 15 years about conflicting measurements of the charge radius of a hydrogen atom's proton
[...]
The discrepancy hinted at possible exciting new physics. Now the debate seems to be winding down with the latest experimental measurements, described in two recent papers published in the journals Nature and Physical Review Letters, respectively. And the evidence has tilted in favor of a smaller proton radius and against new physics.
[...]
As previously reported, most popularizations discussing the structure of the atom rely on the much-maligned Bohr model, in which electrons move around the nucleus in circular orbits. But quantum mechanics gives us a much more precise (albeit weirder) description.
[...]
Hydrogen atoms are the simplest nuclei, with a single proton orbited by an electron, so that's typically what physicists have used for their experiments to measure the proton's charge radius. For a long time, the accepted value was .876 femtometers—a "world average"
[...]
Muon spectroscopy measurements first caused the problem back in 2010. Physicists at the Max Planck Institute of Quantum Optics used muonic hydrogen, replacing the electron orbiting the nucleus with a muon, the electron's heavier (and very short-lived) sibling.
[...]
The physicists expected to measure roughly the same radius for the proton as prior experiments, only with less uncertainty. There should be no difference (other than mass and lifetime) between the electron and the muon, theoretically. Instead, they measured a significantly smaller proton radius of 0.841 femtometers, 0.00000000000003 millimeters smaller, well outside the established error bars. It was five standard deviations from the value obtained by other methods.
[...]
Subsequent measurements by various groups were inconclusive. For instance, in 2013, the same international team performed muon-based experiments that confirmed their 2010 value, producing a measurement of 0.84 femtometers for the proton's radius, with a discrepancy of 7 sigma.
[...]
However, two experiments using regular hydrogen to measure the proton radius produced mixed results: A 2017 study also confirmed the 2010 result, while a 2018 measurement was in line with the larger value before the 2010 experiment.
[...]
That brings us to the latest two papers, both of which involved experiments with hydrogen atoms in a vacuum chamber.
[...]
Based on the combined results, the proton has a radius of about 0.84 femtometers, or less than 1 million-billionth of a meter, once again in keeping with the 2010 measurement that kicked off the debate.

"The proton radius should be a universal property; it should give the same result no matter how you look at it," Juan Rojo, a physicist at Vrije University Amsterdam in the Netherlands, who was not involved in either experiment, told New Scientist. "This is why these two papers are quite nice, because they provide different perspectives to the same number."
[...]
this is disappointing for the discovery of new physics, but it is exciting that we are performing such stringent tests of the Standard Model.

Bankers and bank regulators are scrambling to figure out what to do:

High-ranking members of Britain's government and banking sector are reportedly scrambling to figure out what to do about cybersecurity holes found by Claude Mythos Preview, Anthropic's new automated system for making tech elites—and now financial elites—wet their pants.

In case you weren't aware, last week Anthropic declared its unreleased model, Claude Mythos Preview, scary as heck and simply too powerful to unleash upon the world.

In addition to claiming that Claude Mythos Preview is a sneaky little dickens , a post on Anthropic's frontier red team blog describes it as essentially the world's most dangerous super-hacker . The passage below summarizes the apparent hacking hazard pretty well. (Note that "zero-day vulnerabilities" are vulnerabilities in code known only to the person or AI agent who found them):

During our testing, we found that Mythos Preview is capable of identifying and then exploiting zero-day vulnerabilities in every major operating system and every major web browser when directed by a user to do so. The vulnerabilities it finds are often subtle or difficult to detect. Many of them are ten or twenty years old, with the oldest we have found so far being a now-patched 27-year-old bug in OpenBSD—an operating system known primarily for its security.

Now, according to the Financial Times, the Bank of England and regulators at the U.K.'s Financial Conduct Authority and Treasury will hold "urgent discussions" with that country's National Cyber Security Centre to figure out a course of action. Anonymous sources who spoke to the Financial Times said (quite Britishly) that a planning meeting will be held "in the next fortnight."

How scared is the U.K.? This issue is also the next big priority of the UK's "Cross Market Operational Resilience Group," according to the Financial Times. That group includes members of the U.K.'s National Cyber Security Centre, the Financial Conduct Authority (their equivalent of the SEC), and His Majesty's Treasury. It's co-chaired, the Financial Times says, by someone at the Bank of England with the title "executive director for supervisory risk."

Meta is turning Zuckerberg into Clippy so he can answer all your queries and gives you feedback and support ... I'm sure the staff will just feel the motivation flow over them as their great leader appears to them in person, or in avatar form as their very own Clippy. Zucky?

The AI clone of Zuckerberg, Meta's founder and chief executive, is being trained on his mannerisms and tone as well as his public statements and thoughts on company strategy.

[...] Synthesia, a $4bn UK-based startup that makes realistic video avatars, said the idea of a senior company executive using AI to increase their internal presence was not science fiction any more.

"When you add realistic AI video and voice, engagement and retention go up significantly," said a Synthesia spokesperson. "People work better when the information they need is delivered by a familiar face or voice."

Until Zuckerberg launches his AI self, however, he will have to present in person at meetings with thousands of Meta staff, such as the one he carried out in 2023 two days after he announced that 10,000 employees would be laid off. Then, the tech chief was questioned by "rattled" staff about job security and the future of remote working.

Ukrainian ground robots and drones have demonstrated how to overcome a Russian military position by themselves while forcing the surrender of Russian soldiers, claimed Ukrainian President Volodymyr Zelenskyy.
[...]
The claim by Zelenskyy has not been independently verified but was accompanied by a promotional video in which he described Ukraine's military robots as having completed over 22,000 missions in the last three months. Ukraine's defense ministry also recently described a threefold increase in the Ukrainian military's uncrewed ground vehicle missions over the last five months, with more than 9,000 robotic missions conducted in March, according to Scripps News.
[...]
Zelenskyy's statement may refer to an event that occurred in the Kharkiv Oblast in northeastern Ukraine last year, according to The Independent. It referenced a statement by the Ukrainian 3rd Separate Assault Brigade detailing how the unit had used flying drones and "kamikaze" ground robots to attack fortified Russian frontline positions at that time.
[...]
The increased emphasis on battlefield robots coincides with how deadly flying drones have made the modern battlefield for human soldiers. Persistent drone surveillance and drone strikes have created a "kill zone" stretching 12 miles (20 kilometers) beyond the frontline positions as of February 2026, forcing individual soldiers to hunker down or rely on nighttime darkness, anti-thermal cloaks, or foggy conditions to move about without risking a drone strike. Such drones are now inflicting the majority of battlefield casualties on both sides as the full-scale war enters its fifth year.
[...]
By comparison, ground robot usage in the Russo-Ukrainian war has been relatively modest, with Ukraine reporting thousands of ground robot missions per month versus hundreds of thousands of drone sorties per month. Yet the latest numbers suggest the Ukrainian military has stepped up its effort to deploy more robots for supply runs and medical evacuations, which can reduce human exposure to drone threats.
[...]
One example of such robots is the Droid TW 12.7 developed by the Ukrainian company DevDroid. As described in the company's marketing material, the tracked robot is armed with an M2 Browning machine gun mounted on a remotely controlled turret and capable of traveling up to 15 miles (25 kilometers) at a top speed equivalent to an adult's walking pace.
[...]
A deputy battalion commander of Ukraine's 38th Marine Brigade told The Kyiv Independent that robots attempting to evacuate wounded soldiers failed to reach the positions in four out of five cases due to such complicating factors.

Like drones, robots can also face communication challenges from signal loss and enemy electronic warfare, according to the Lowy Institute.
[...]
The commander of Ukraine's 3rd Army Corps suggested that if military units incorporate more robots, they could reduce their infantry ranks by up to 30 percent by the end of this year. If Ukraine succeeds in that goal, it would mark another notable step for the growing robotic presence on the battlefield.

Judge said ban, which originated in Reconstruction era to thwart liquor tax evasion, actually reduced tax revenue:

A US appeals court on Friday declared a nearly 158-year-old federal ban on home distilling to be unconstitutional, calling it an unnecessary and improper means for Congress to exercise its power to tax.

The fifth US circuit court of appeals in New Orleans ruled in favor of the non-profit Hobby Distillers Association and four of its 1,300 members.

They argued that people should be free to distill spirits at home, whether as a hobby or for personal consumption including, in one instance, to create an apple-pie-vodka recipe.

The ban was part of a law passed during the US's post-civil war Reconstruction era in July 1868, in part to thwart liquor tax evasion, and subjected violators to up to five years in prison and a $10,000 fine.

Writing for a three-judge panel, the circuit judge Edith Hollan Jones said the ban actually reduced tax revenue by preventing distilling in the first place, unlike laws that regulated the manufacture and labeling of distilled spirits on which the government could collect taxes.

She also said that under the government's logic, Congress could criminalize virtually any in-home activity that might escape notice from tax collectors, including remote work and home-based businesses.

"Without any limiting principle, the government's theory would violate this court's obligation to read the constitution carefully to avoid creating a general federal authority akin to the police power," Jones wrote.

The US justice department had no immediate comment. Another defendant, the treasury department's alcohol and tobacco tax and trade bureau, did not immediately respond to a request for comment.

Devin Watkins, a lawyer representing the Hobby Distillers Association, called the ruling an important decision about the limits of federal power.

Andrew Grossman, who argued the non-profit's appeal, called the decision "an important victory for individual liberty" that allows the plaintiffs to "pursue their passion to distill fine beverages in their homes".

"I look forward to sampling their output," he said.

The decision upheld a July 2024 ruling by the US district judge Mark Pittman in Fort Worth, Texas. He put his ruling on hold so the government could appeal.

Is it legal to distill spirits at home in other parts of the world?

Conversation framing or Social-engineering the Customer support AI bots. Making them do things to burn company tokens. One just can't stop laughing.

Users are tricking enterprise chatbots into performing complex AI computations unrelated to customer support, with potentially costly governance and ROI ramifications.

He adds: "Anyone who's spent five minutes with these tools knows you can steer past a system prompt with basic conversational framing, which is exactly what [is happening to enterprises today]. The system authenticates the session, not the intent."

"A normal customer service interaction of 'Where's my order? What are your hours?' runs maybe 200 to 300 tokens. Someone asking the bot to reverse a linked list in Python is generating more than 2,000 tokens easy.

An amendment to a recent lawsuit could change the narrative significantly, and just weeks before trial:

Does “injecting chaos into the proceedings” sound like something Elon Musk of all people would do during a lawsuit? Well I hope you’re sitting down because he’s being accused of doing just that in a court filing from OpenAI reported by Bloomberg on Saturday.

Earlier this week, Musk amended his lawsuit against OpenAI and Microsoft. He's still seeking an eye-popping $134 billion for allegedly engaging in what he characterizes as fraud by switching from non-profit to for-profit status. Now, however, he's asking for potential damages to be paid not to him, the richest person in the world, but instead to OpenAI's nonprofit.

He also wants Sam Altman, the company’s CEO, and Greg Brockman, its president, to be tossed out.

OpenAI says this is Musk “trying to recast his public narrative about his lawsuit.” Indeed it is a significant change to how the story might be framed. Rather than a zillionaire seeking yet another giant sum of money, it becomes a zillionaire seeking to restore the corporate structure of a firm he was allegedly wronged by.

OpenAI characterized Musk making such a move just weeks before a trial set to start later this month as a “legal ambush,” that is “legally improper and factually unsupported.” The filing also says, “Musk’s proposed amendment would require the presentation of different evidence and different witnesses than the case he sponsored until three days ago.”

"A new memory chip prototype, described in a recent Science paper, may offer a practical solution to this issue. According to the research team, the chip blueprint is a tiny sandwich of extreme materials that works reliably even at temperatures of 1,300 degrees Fahrenheit (about 700 degrees Celsius)—and probably could function beyond these temperatures, as that number merely represents the maximum provided by the testing equipment."

[...] "The chip is what's called a memristor, or an electrical device that both stores information and performs computing operations. The component is a tiny "sandwich" of three layers: tungsten on the top, hafnium oxide ceramic in the middle, and graphene on the bottom. Notably, tungsten has the highest melting point of any metal at 6,192 degrees Fahrenheit (3,422 degrees Celsius), whereas graphene is a flat sheet of carbon just one atom thick.

These unique physical properties enabled the creation of the novel chip, which ran on a measly 1.5 volts to process data for over 50 hours at 1,300 degrees Fahrenheit, the team explained. In that time, the chip powered through more than one billion switching cycles without needing any external modifications. "

The scheme follows a string of security failures at SK Telecom, KT, and LG Uplus:

South Korea's Ministry of Science and ICT said on Thursday that SK Telecom, KT, and LG Uplus — the country’s three major carriers — will provide more than seven million mobile subscribers with unmetered 400 Kbps data once their monthly allowances run out. First floated as part of a broader package of consumer-protection measures being assembled in parallel with its response to spiking memory and PC component prices, Deputy Prime Minister and Minister for Science and ICT Bae Kyung-hoon announced the program as one of many new obligations imposed on the three carriers in response to a sequence of security failures over the past year, calling unlimited, universal access one of the “basic telecommunications rights” that operators are expected to fund themselves.

400 Kbps might not sound like much, especially given that 5G can reach peak speeds in excess of 1 Gbps and standard-definition video streaming requires speeds of around 5 Mbps as a baseline, but it’s more than enough for very rudimentary activities like messaging and VoIP audio, or two-factor authentication.

It’s worth noting that the fallback to 400 Kbps only applies once a customer burns through their paid monthly cap, replacing the hard cutoff or overage charges that previously kicked in on affected plans.

Alongside the obligation to provide unmetered 400 Kbps access, the three operators have committed to increasing data and calling allowances for seniors, upgrading Wi-Fi services on public transport, and introducing 5G plans priced at $13.50 or below. Bae also pushed the carriers to direct more capital toward network buildout for AI workloads.

"Having gone through last year's hacking incidents, the weight of the telecom companies' responsibilities and roles has become even clearer," Bae said in a press release, emphasizing, “We have now reached a point where we must move beyond pledges not to repeat past mistakes and respond with renewal and contribution at a level of complete transformation that the public can tangibly feel." He went on to say that it’s important for the government to contribute to people’s livelihoods, including by guaranteeing what he called “basic telecommunications rights” for all citizens.

Each of the three network operators has been hit by a significant security incident in recent months. SK Telecom suffered a large-scale subscriber data leak, whereas KT was found to have deliberately pushed malware to roughly 600,000 of its own subscribers who were using a third-party BitTorrent-based file-sharing service, resulting in missing files and disabled PCs.

In the process of converting carbon dioxide into useful chemicals such as ethylene—a key precursor for plastics—a major challenge has been the flooding of electrodes, where electrolyte penetrates the electrode structure and reduces performance. KAIST researchers have developed a new electrode design that blocks water while maintaining efficient electrical conduction and catalytic reactions, thereby improving both efficiency and stability.

A research team led by Professor Hyunjoon Song from the Department of Chemistry has developed a novel electrode structure utilizing silver nanowire networks—ultrafine silver wires arranged like a spiderweb—to significantly enhance the efficiency of electrochemical CO₂ conversion to useful chemical products. The research was published in Advanced Science.

In electrochemical CO₂ conversion processes, a long-standing issue has been flooding, where the electrode becomes saturated with electrolyte, reducing the space available for CO₂ to react. While hydrophobic materials can prevent water intrusion, they typically suffer from low electrical conductivity, requiring additional components and complicating the system.

To overcome this, the research team designed a three-layer electrode architecture that simultaneously repels water and enables efficient charge transport. The structure consists of a hydrophobic substrate, a catalyst layer, and an overlaid silver nanowire (Ag NW) network, which acts as an efficient current collector while preventing electrolyte flooding.

A key finding of this study is that the silver nanowires do more than just conduct electricity—they actively participate in the chemical reaction. During CO₂ reduction, the silver nanowires generate carbon monoxide (CO), which is then transferred to adjacent copper-based catalysts, where further reactions occur.

This creates a tandem catalytic system, in which two catalysts cooperate sequentially, significantly enhancing the production of multi-carbon compounds such as ethylene.

The electrode demonstrated outstanding performance. It achieved 79% selectivity toward C₂₊ products in alkaline electrolytes and 86% selectivity in neutral electrolytes, representing a world-leading level. It also maintained stable operation for more than 50 hours without performance degradation.

These results indicate that most of the converted products are the desired chemicals, while also overcoming the durability limitations of conventional systems.

Professor Hyunjoon Song stated, "This study is significant in showing that silver nanowires not only serve as electrical conductors but also directly participate in chemical reactions," adding, "This approach provides a new design strategy that can be extended to converting CO₂ into a wide range of valuable products such as ethanol and fuels."
