Dr. Connie Lehman introduces the FDA-authorized platform from Clarity, the first to predict breast cancer risk from routine imaging. The approach aims to personalize screening, helping clinicians tailor surveillances and preventive strategies. This milestone highlights how machine learning is enabling earlier risk stratification, potentially shifting screening to be more proactive and targeted. CBS News details how the tool analyzes imaging data to provide risk scores that can guide shared decision-making between patients and doctors.

October 23, 2025, 10:02 PM EDT. With NASA reopening the Artemis III lunar lander contract, the spotlight shifts to whether Blue Origin can upend SpaceX. The debate pits a rival private space company against the incumbents as NASA weighs bids and performance histories. Analysts note Blue Origin's readiness with the New Glenn and a track record in commercial lunar ambitions, while SpaceX touts the proven capabilities of its Starship pedigree. The revival of the bidding process raises questions about schedule, cost, safety, and national prestige. Beyond contract awards, the competition highlights how NASA policy, funding cycles, and the private-space race shape the path to the Moon, potentially redefining who wins future deep-space contracts - and at what cost.

October 23, 2025, 9:44 PM EDT. A rare look at how Hollywood is already embracing AI. ABC News' Nathan Rousseau Smith examines AI cloning for A-list actors and the emerging world of AI film studios working with talents like Natasha Lyonne, South Park creators, and Darren Aronofsky, plus Google's Veo. The piece illustrates how modern productions use AI, from performance capture and voice synthesis to automated editing and visual effects, while raising questions about consent, IP ownership, and the future of jobs in the industry. It underscores a shift toward data-driven decision-making and suspenseful new storytelling tools, signaling that the line between human performance and machine-generated imagery is increasingly blurred in contemporary cinema.

October 23, 2025, 9:12 PM EDT. Space weather threats are real: a massive solar storm could disrupt satellites and cripple global services. The European Space Agency (ESA) is training the frontlines of its fleet by running simulations for new spacecraft, like Sentinel 1-D, under a three-stage scenario tied to a Carrington-like event. The exercise mirrors real risks: a fast X45 flare can knock out GPS signals, while a flood of high-energy particles can flip bits in memory and avionics. Operators must perform damage control and conserve fuel as the atmosphere expands. The effort underscores potential economic losses and the need for robust shielding and contingency planning within the Copernicus Programme.

October 23, 2025, 9:08 PM EDT. Nvidia and Uber are teaming up to advance autonomous driving by training Nvidia's Cosmos World foundation model on Uber's vast driving data. The collaboration aims to improve simulation precision, speed up post-training iterations, and ensure reliable behavior in challenging conditions using Nvidia's DGX Cloud and DRIVE platforms. By feeding real-world scenarios-intersections, airport pickups, varied weather-into Cosmos, the partners hope to shorten testing cycles and enable vehicles to reason through rare events they haven't seen. The effort aligns with Nvidia's roadmap for AI-enabled driving, emphasizing end-to-end architectures and scalable simulation with tools like Cosmos Predict and Cosmos Transfer to generate edge cases. The partnership signals deeper AI-mobility convergence as both companies push toward Level 4 autonomy.
