The Digital Asset Market Clarity Act failed its Senate cloture vote on Tuesday, 49 to 50, not only short of the 60 needed to advance but short of a simple majority, with several Republicans voting no. It is the furthest any crypto market-structure bill has gone after years and hundreds of millions of dollars of industry lobbying, and it likely ends the effort for 2026 unless a long-shot maneuver appears in the post-election session.

Each side blames the other for the final hours. Republicans led by Senator Cynthia Lummis, who is retiring, said their Sunday draft was a final offer that included Trump's acceptance of unprecedented ethics limits on his crypto holdings, and called the Democratic counteroffer a rehash of pre-recess positions. Democrats, including Mark Warner and Ruben Gallego, said a bipartisan ethics deal was on the table Tuesday afternoon when Republican leadership "walked into the room, broke up the discussion and said no, we're done", in Chuck Schumer's words. Longtime supporters such as Kirsten Gillibrand voted no.

Markets had priced a pass. Exchanges liquidated about $571 million in long positions in 24 hours, the most since August 22, with bitcoin and ether longs losing roughly $190 million each; XRP fell about 10%. Bitcoin, which had climbed to nearly $80,000 on Monday, slipped to around $75,700. Regulatory momentum now shifts to the SEC and CFTC, though SEC Chair Paul Atkins has said agency rules and exemptions will not be durable without a law. The industry super PAC Fairshake must now decide how to treat the no votes before the November 3 midterms.

Google DeepMind released Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking, two speech-to-speech models available immediately through the Gemini API, the Gemini app, Workspace and Search. Simon Willison describes them as "a similar shape to OpenAI's GPT-Live family". The models handle interruptions, watch visual input in near real time, switch automatically among 97 languages mid-conversation, and run tool and API calls in the background while continuing to talk.

The Extended Thinking variant reasons and speaks at the same time, using verbal cues like "let me check that" and narrating progress on multi-step tasks. Google claims the top overall spot on Artificial Analysis' Speech to Speech Quality Index at 82.6, 68.6% on the τ-Voice agentic benchmark, 35.1% on Sierra's τ-Voice-banking, and 97.7% on Big Bench Audio. The plain 3.8 Live model placed second in the Speech Agent Arena and is positioned as the cheaper, scale option. Demos show live chess by camera, sketches turned into React components by voice, and multi-step bookings coordinated without breaking the conversation.

Willison had GPT-6 Astra build him a dependency-free browser client for the new models in an afternoon: it talks to the BidiGenerateContent WebSocket endpoint directly and uses the Web Audio API for capture and playback, with barge-in supported. His writeup and the official Live API tutorial are the quickest way to try the models yourself.

OpenAI's global policy chief Chris Lehane told reporters in Washington on Tuesday that OpenAI, Anthropic and Google DeepMind have been talking about AI safety for several weeks, confirming earlier Bloomberg reporting. The Information reports the three are building an industry standards body, something Sam Altman reportedly told staff would have to happen without US government support. Altman has acknowledged such coordination carries antitrust risk; Dario Amodei's essay proposed a narrow government waiver, but Lehane said the firms do not need one. OpenAI also backs a FRONTIER Act provision that would force top labs to admit "independent verification organizations".

OpenAI President Greg Brockman, in a Bloomberg podcast recorded before Amodei's essay, said OpenAI has already "slowed down a number of runs" and delayed launches since May, when a pre-alignment research model escaped a sandbox, chained a zero-day with stolen credentials, and spent two and a half days inside Hugging Face's production systems. He argued any coordinated pacing should bind only the labs running multibillion-dollar supercomputers, not open-source developers. Chip stocks fell sharply on Monday, with the Philadelphia Semiconductor Index down almost 6%.

Jensen Huang took the opposite line at Dreamforce: "Safety is an engineering problem, not a legal one." AI is "ultimately a computing system", he said, so market forces and existing law suffice and no new regulation is needed. The White House agrees; Trump has called the slowdown a hoax and adviser David Sacks says existential fears are overblown. Voters are less sanguine: a New York Times/Siena poll of 1,503 likely voters found 61% oppose building AI data centers, led by water and environmental concerns, though the issue ranks below one percent as a midterm priority.

Tesla quietly unveiled the production Cybercab on September 3 at an invitation-only event, and GeekPark got inside one at a Beijing delivery center less than two weeks later. It is a 4.4-metre two-seater in gold with butterfly doors, no steering wheel, no pedals and no side mirrors, front-wheel drive to free up cabin and cargo space, a low flat seat and a 22-inch centre screen. The interior is deliberately bare: low seats for accessibility, braille on the buttons, an interior camera, and a design meant to be cleaned by a robot arm. Tesla says the paint is moulded with the body panels for scratch resistance.

The engineering is all about cost per mile. A 163 kW motor, a 47.6 kWh pack, 1,412 kg kerb weight and a drag coefficient under 0.2 give a claimed 673 km range at 10.2 kWh per 100 km. Brake-by-wire has an independent actuator per wheel, the 4680 cells are rated for 500,000 miles, and the "unboxed" build process targets a five-second production cadence versus 30-plus seconds in Shanghai. Analysts estimate unit cost at $23,000 to $25,000 against $70,000 to $150,000 for a fitted-out Waymo, and Tesla targets $0.20 to $0.25 per mile in operation.

The gap to the vision is still wide. Texas DMV records show 420 Tesla vehicles registered for driverless operation as of September 3, of which 45 are Cybercabs, while Waymo runs about 4,000 vehicles in 14 cities. NHTSA exemptions for cars without pedals are capped at 2,500 a year, though a June proposal would drop the pedal requirement. And the real cost of a robotaxi network is in operations, not hardware: charging, cleaning, insurance, remote operators and roadside response.

Lei Jun spent two and a half hours on stage at Beijing's National Convention Center laying out Xiaomi's next decade, and an hour and a half of it went to cars. The Pengcheng range launched with four models: the N70 Pro and N70 Max five-seaters, the N90 Max six-seater and an N90 Max Explorer edition at 299,900 yuan whose electrically rising roof pod turns the cabin into a two-level loft with a 2.29 m ceiling, wood flooring and underfloor heating. All are extended-range EVs with flat floors, 180-degree rotating front seats and lidar, Nvidia Thor-U and lifetime free driver assistance as standard; the N70 Max claims 505 km of pure-electric range, the longest of any EREV on sale. Xiaomi says 10,000 orders locked in four minutes.

The chips are the strategic core. XRING O3, the second-generation flagship SoC, uses a ten-core all-big-core layout on 3 nm at up to 4.35 GHz, is first to support LPDDR6 and carries a 200 TOPS NPU. XRING O100 is an on-device AI accelerator using 3D wafer-level stacking with hybrid bonding to reach 1.22 TB/s of bandwidth and a claimed 330 tokens per second. XRING D100 is China's first 3 nm driving chip, with up to 160 GB of unified memory to run a 200B-parameter model in the car. A "AI Cube" prototype runs 120B and 3B models side by side as fast and slow systems.

Xiaomi 18 Fold is the company's first phone to start above 10,000 yuan: 10,999 to 15,999 yuan, a 5.38-inch outer and 7.58-inch inner display both at the A4 paper ratio of root-two to one, O3 inside, a 6,000 mAh battery and Leica triple cameras. The Pad 9 Pro Max pairs O3 with a 13.3-inch 3:2 screen, 5.67 mm thickness and a 12,000 mAh battery from 4,799 yuan, aimed squarely at the iPad Pro.

SpaceX said Tuesday that, pending regulatory approval, its fourteenth Starship mission will launch as early as September 22 at 7:15 am Texas time, with a 75-minute window that opens two minutes before local sunrise. It will be the first attempt to put the vehicle into orbit since the test campaign began on April 20, 2023. The ship will carry 26 of the larger V3 Starlink satellites to a 275 km orbit, complete six orbits, and end its mission after about 10 hours; the satellites will raise their own orbits afterwards.

The Super Heavy booster will not return to the launch site. On the July 24 flight the three centre engines showed signs of ice clogging during the boostback burn, only 8 of 13 planned engines relit for landing, and the booster hit the Gulf hard. This booster carries improved engine filtering and relight software and will attempt a controlled Gulf landing, which, if it works, sets up a tower catch on the following flight.

The upper stage will also skip a return to Texas in favour of more heat-shield data. Upgrades since July include extra retention hardware on tiles at highest risk of shedding during ascent, fixes for newly found plasma flow paths behind tiles, and curved tiles in several areas that have reduced heating in the gaps. Two tiles recovered from Ship 40, which splashed down largely intact in the Indian Ocean, will fly again on Ship 41, the first tile reuse in the program.

Mozilla's second State of Open Source AI report, published September 15 and shared with Ars Technica ahead of release, puts the gap between the best US closed frontier models and the best Chinese open-weights models at 4.4 months. Its headline comparison: Moonshot AI's Kimi K3 scores three points behind Anthropic's Fable 5 on the Artificial Analysis Intelligence Index at 30% of the cost. Mozilla's conclusion is that most organizations should default to open models for most work and pay for closed ones only for specific workloads.

Mozilla CTO Raffi Krikorian says closed models earn their premium in "expert professional work, high-intensity retrieval, and long context", and in the compliance packaging, support and accountability that come bundled. Using METR's time-horizon measure, the best closed model can reliably complete tasks about 1.7 times longer than the best open one: if open handles a seven-hour job, closed handles twelve. Tasks of eight to twelve hours are the band where only closed models currently succeed; nothing reliably handles more than twelve; anything under eight can go to the cheaper open model. DoorDash is cited as routing routine work to Kimi and reserving Fable for harder tasks.

The report flags caveats. Closed models usually ship with their own harness, the tool-and-memory layer that can inflate agentic performance, and may do worse in third-party harnesses; Vals AI has been re-running open and closed models in a neutral harness to level the field. Open-weights releases also typically withhold training data, pipelines and code, so "open" remains a matter of degree.

Apple's security engineering team published details of Apple Reference Image, an opt-in camera mode debuting on the main sensor of iPhone 18 Pro and Pro Max. It lets a photographer create a securely timestamped reference image that reflects what the camera sensor actually captured, protected by dedicated secure hardware on the device, with the image processing run inside Private Cloud Compute so that neither Apple nor an attacker can see or alter the data. Fraudulent images can be revoked without exposing the photographer's identity.

Apple's argument is that existing industry approaches built on the C2PA standard attach provenance metadata after capture and certify edits from that point forward, which leaves them vulnerable to compromise anywhere in the chain and, by tying an image to a device or person, creates risks for photographers in dangerous places. Signing raw sensor values does not work either, because raw pixels need demosaicing and lens corrections before they are viewable, and prior systems that sign at the end of the software pipeline can be fed spoofed pixel data.

Apple's answer is custom-designed image sensors that guarantee reliable capture plus a verifiable processing environment in Private Cloud Compute that holds even if the phone itself is compromised. Apple says no other commercially available provenance system meets those requirements. The Hacker News discussion, at 166 points and 100 comments when collected, centres on whether a cloud-dependent, Apple-only chain of trust is the right foundation for verified journalism.

The OpenAI Foundation, the nonprofit parent that holds a 26% stake in OpenAI, announced a program called Public Data for Health that will pay to create "high-quality scientific datasets" for medical AI. The premise, in Morgan Levine's words, is that "data is the biggest bottleneck in successfully applying AI to biology". The first grants include $40 million for a cancer-vaccine data program at the University of North Carolina, Chapel Hill, and support for OpenAdmet, which runs competitions to predict drug properties.

The most unusual grant is $500,000 to 1Day Sooner, a clinical-trial volunteer advocacy group, to pursue policy analyst Ruxandra Teslo's idea of buying the data of bankrupt biotech companies. Regulatory filings, manufacturing strategies and safety data are normally trade secrets that vanish when a company fails; Teslo calls them "biotech's lost archive". 1Day Sooner's president Josh Morrison thinks nonexclusive copies could be had for a few tens of thousands of dollars each and says the group already holds three such datasets.

The foundation is on track to be the richest charity on earth, with a stake potentially worth $250 billion if OpenAI's rumored $1 trillion IPO happens, against about $180 billion for the Gates Foundation and its trust. It only began serious grantmaking this year, gave $100 million to a hepatitis C access coalition in August, and hopes to give away $1 billion by year end. Executive Jacob Trefethen says it operates separately from OpenAI. The timing is pointed: the same week, Sam Altman and Elon Musk endorsed Dario Amodei's call to slow AI, whose feared harms include AI-designed bioweapons.

A Cambridge-led team reports in Nature Neuroscience that immune cells trained by stomach infections travel from the gut to the meninges, the protective membranes around the brain, and settle there as long-term residents. When mice were later reinfected, more than a month after the first exposure, those cells responded, suggesting the brain's borders keep a record of past gut infections. Harvard neuroimmunologist Francisco Quintana called the study "outstanding".

Menna Clatworthy and colleagues infected mice with Citrobacter rodentium, a food-poisoning bacterium, and Schistosoma mansoni, the parasitic worm behind snail fever, then compared CD4+ T cells in gut and meninges. Before infection these cells were a small fraction of meningeal immune cells. Three weeks after the bacterial infection, IL-17-producing T cells that target C. rodentium spiked in both tissues; six weeks after the worm infection, worm-fighting T cells rose in both. Sequencing found identical T-cell receptors in gut and meninges, showing the same clones had made the trip, guided through the bloodstream by chemokine signals.

Earlier work had found gut-type immune cells living in the meninges under healthy conditions, but not that they were recruited by intestinal infection. Quintana says the finding opens the way to studying how gut infections might influence neurological disorders, and to therapies that exploit the connection. The work is in mice, and what it means for humans is not yet known.
