NASA DART mission uncovers ‘cosmic snowballs in space’ around asteroid moon Dimorphos and the Didymos asteroid system. This episode explains how an asteroid impact mission revealed near-Earth asteroids quietly trading material across space rocks and asteroids. Learn how NASA space discoveries are rewriting asteroid science, from fast-spinning primaries to debris-sharing asteroid moon systems. What You'll Learn: How the NASA DART mission was designed as an asteroid impact mission and why Dimorphos was chosen as the target in the Didymos asteroid system. What the DRACO camera saw in its final images and how a 0.6 m per pixel resolution at 1,000 km revealed faint streaks interpreted as “cosmic snowballs in space.” Why Didymos spinning once every 2.26 hours puts it near the theoretical breakup limit and what that means for rubble-pile asteroids. How sunlight can spin up near-Earth asteroids (the YORP effect) until they shed debris that can drift toward nearby asteroid moons. The orbital relationship between Didymos and Dimorphos—an 11.9-hour orbit at roughly 1.2 km distance—and how that close pairing enables material exchange. Why these “cosmic snowballs” are the first direct visual proof that active processes constantly reshape near-Earth asteroids. What this discovery means for future planetary defense missions and how understanding asteroid moon systems improves impact risk assessments. How NASA space discoveries like DART help scientists better predict the structure, evolution, and behavior of space rocks and asteroids.

This episode dives into new research on UK public opinion on health data sharing, drawing on in-depth NDORMS focus groups that explore what makes people willing—or unwilling—to share their medical records for AI research. You’ll hear how participants responded when potential benefits were made concrete, such as better diagnostics, faster care, and more efficient NHS services. The conversation unpacks why many people express strong support for non-commercial, NHS-led AI projects aimed at clear public good, while showing far more skepticism toward sharing data with for-profit tech companies. We break down the conditions that increased support: robust privacy safeguards, meaningful consent, transparent governance, ongoing public oversight, and guarantees that the NHS retains control over how data and resulting AI tools are used. The discussion also examines how expectations shift when financial profit is involved, and why some participants want patients or the NHS to share in that value if their data underpins commercial tools. The episode highlights the UK Biobank as a large-scale proof of concept for secure health data use—enabling thousands of research papers with zero reported re-identification incidents—and what that example does and does not resolve in public debates about trust. Throughout, we connect these findings to broader questions in AI in healthcare ethics, patient data privacy, and the responsibilities of health systems and regulators. Whether you’re working in digital health, designing AI tools for medicine, setting NHS data policy, or simply a patient curious about how your records might be used, this episode offers a clear, research-based guide to what the UK public actually says it needs in order to trust sharing medical data for research and AI. What You'll Learn: Why UK public opinion on health data sharing for AI is tightly linked to visible NHS-led public benefit and clear explanations of outcomes How thoughtful communication about risks, safeguards, and governance can significantly increase willingness to share medical data for research What focus group participants considered acceptable conditions for NHS-led, non-commercial AI projects versus commercial, for-profit initiatives How expectations around NHS control, benefit-sharing, and faster access to care shape public trust in AI and data partnerships What the UK Biobank experience shows about large-scale health data use, research impact, and maintaining public confidence through zero reported re-identification incidents Which ethical principles—transparency, accountability, consent, and oversight—people want embedded in AI in healthcare systems How policymakers, clinicians, and AI developers can use evidence from the BMJ Digital Health and AI study to design more trusted data-sharing frameworks About the Guest: This episode features researchers involved in a new NDORMS study published in BMJ Digital Health & AI, who work at the intersection of health data science, medical ethics, and public engagement.
