Romantic jealousy: evolved alarm, insecurity, or something you can unlearn?

Evolutionary psychologist David Buss describes jealousy as an evolved response to threats to a relationship that runs from vigilance to violence, psychiatrist Paul Conti separates it from envy, Marc Brackett teaches people to tell the two apart and find the cause, sex researcher Aella describes managing jealousy inside polyamory, and Pastor Michael Todd ties it to self-worth. How you explain jealousy decides whether you treat it as information about the relationship, a problem in yourself, or a warning sign of danger.

Skip the autopilot questions: how to start conversations that go deeper

Vanessa Van Edwards says to ask for stories instead of facts and offers research-based conversation starters, mentalist Oz Pearlman tells people to skip the autopilot questions, Charles Duhigg finds that supercommunicators ask deep questions about values and feelings, and Michael Bungay Stanier opens with a question that hands the agenda to the other person. Their shared claim is that the first question sets the depth of the whole exchange, which makes better questions the simplest fix for small talk that goes nowhere.

Warmth and Competence, Clearly Signaled: How to Make a Strong First Impression

Vanessa Van Edwards says charisma is warmth and competence shown together, and that capable people get overlooked when they fail to signal either one. Oz Pearlman, Terrence J and former Secret Service agent Evy Poumpouras describe the signals that carry it in the first seconds, from the approach and eye contact to names and voice, and they are frank about what such cues cannot prove.

Why dating apps feel so hard, and what dating researchers suggest instead

Behavioral scientist Logan Ury says much of what people blame on apps comes from their own filters and from shopping for partners by checklist, psychologist Paul Eastwick shows that ratings of strangers miss the attraction that builds as people get to know each other, and Matthew Hussey advises long-term singles on dating without burning out and creating their own dating culture. Their explanations point to changes a single person controls, which is more useful than deleting the apps in frustration.

The roommate marriage: how couples drift apart and find their way back

Mel and Chris Robbins describe about a decade of feeling like roommates, divorce lawyer James Sexton says marriages fail from disconnection slowly and then all at once and calls the first stage of divorce the unattended marriage, the Gottmans describe avoiders and roommate marriages, and Gary John Bishop says relationships go wrong at a turn nobody noticed. Seeing drift as the usual cause, more than any single betrayal, shows couples what to watch for and why small rituals of connection are the way back.

What big tech gives to open source, and what it takes

Mark Zuckerberg and Yann LeCun explain why Meta gives its AI models away, while Jean-Baptiste Kempf and Kieran Kunhya describe how large companies lean on FFmpeg and VLC and add to their maintainers' load. Set side by side, they show the two faces of corporate involvement in open source and why the relationship is not simply generous or exploitative.

Biology as blueprint: what animals and cells teach robot designers

Russ Tedrake studies a dead fish that swims and bodies that adapt, Marc Raibert chases natural movement in legged machines, and Neil Gershenfeld takes the ribosome as his model for robots that build robots. Each borrows a different lesson from living things, which shows how much of robotics is reverse-engineering nature.

Teaching machines what we actually want is a two-way job

Anca Dragan calls reward engineering a collaboration, Michael Littman recalls the role of the human expert in early reinforcement learning, and Neuralink's Matthew MacDougall describes brain and decoder learning together. Across very different systems, the machine and the person each have to adapt to the other for the goal to come through.

The half-automated car: why sharing control with a machine is risky

Anca Dragan describes a trap in semi-autonomous driving, Rana el Kaliouby builds driver monitoring to watch the human, and Lex Fridman draws on Tesla Autopilot to discuss humans working alongside automation. Together they show that the handoff between person and machine is its own design problem, separate from making the car drive well.

Who decides what stays up: Zuckerberg, Wales and Hotz on pressure and control

Mark Zuckerberg and Jimmy Wales describe how Meta and Wikipedia respond when governments push on content and data, and their answers differ because one runs a company with staff and servers and the other a volunteer project with no advertisers. George Hotz, after a short stint inside Twitter, does not discuss government pressure there; his argument is that any single decider, state or owner, is the problem, and that filtering should belong to each user.

The discipline of doubt: how physicists handle results they badly want true

Brian Keating watched a Nobel-level claim dissolve into galactic dust, David Kipping refused to call his best exomoon signal a discovery, and Andrew Strominger treats being wrong as the normal cost of doing physics. Only one of the three results was actually withdrawn, but together they show the habits careful researchers use against their own hopes.
