ESA to build Envision Venus orbiter solo after NASA drops radar contribution

The European Space Agency is pressing ahead with its Envision mission to Venus after NASA signaled it likely can't deliver the US-built synthetic aperture radar it had promised under a 2024 partnership agreement. That radar was meant to be the spacecraft's main tool for mapping the planet's volcanic surface through its thick sulfuric-acid clouds at ten times the resolution of NASA's 1990s Magellan mission. ESA's project scientist says development will continue at full pace regardless.

Feyn releases MultiMatte, a text-prompted matting model built atop Meta's SAM 3

Feyn launched MultiMatte, a background removal tool that lets users type a word or phrase to isolate a specific object in an image while removing everything else. The model fine-tunes Meta's SAM 3 using LoRA, adjusting only 19.49M of its 860M parameters (2.27%), and swaps SAM 3's binary masks for continuous alpha mattes that can render soft edges like hair or translucent objects. On DIS benchmarks, MultiMatte scores 0.893-0.923 compared to SAM 3's 0.649-0.703.

Report: Big Tech and VC-backed startups reap billions from opaque Pentagon deals

A new analysis finds Microsoft, Amazon, and Alphabet collected roughly $28 billion in federal contracts between 2018 and 2022, with the five largest tech contracts from 2019-2022 carrying combined ceilings of at least $53 billion. Separately, venture capital poured nearly $100 billion into defense tech startups from 2021 to 2023, a 40 percent jump over the prior seven years combined.

Anthropic Researcher Coxon Quits AI Industry, Warns of Loss of Control by 2027

Jacob Coxon, who moved from OpenAI to Anthropic earlier this year specifically for its safety-focused reputation, has now left the AI field entirely, saying the industry is on a path toward building systems humans may not be able to control. He told the Wall Street Journal that even Anthropic cannot safely pursue advanced AI without government regulation or a broader industry slowdown, predicting things could spiral by the end of next year. Anthropic's Alignment Science Lead Evan Hubinger publicly backed Coxon, estimating a greater than 10% chance AI could cause human extinction within a decade.

Documentary: Justine Musk says Elon Musk called mothers of his children "breeders"

A new four-hour documentary by Alex Gibney, which premiered at the Venice Film Festival, includes interviews with Elon Musk's first wife Justine Musk, who says he referred to the mothers of his children as interchangeable "breeders." She also described incidents of gaslighting, including Musk misremembering who was holding their infant son when he died of SIDS, and recalled him calling himself "the alpha" at their wedding. Musk has publicly dismissed the film as a "hit piece."

Tern lands $11.26M Army contract for GPS-free vehicle navigation

Austin startup Tern has secured an $11.26 million U.S. Army contract to install its GPS-alternative navigation system in military vehicles. The technology uses a device connected to a vehicle's diagnostics board, paired with a tablet, to calculate location and routing by passively analyzing data the vehicle already generates, rather than relying on satellite signals.
