Research across 145 countries and 508 great apes supports a recurring midlife happiness dip with shared biological factors likely contributing, but the dramatic "crisis" narrative is a cultural amplification affecting only 10 to 20 percent of adults.
Explainers Psychology & BehaviorSince 2011, an estimated 198,000 lithium-ion battery fires have occurred in US structures. As energy density quadruples and researchers push toward 700 Wh/kg, safety standards operating on three-year revision cycles cannot keep pace with the chemistry.
Explainers Physics & EngineeringBatteries dominate the headlines, but they account for only 5% of global grid-scale energy storage. The other 90% exploits gravity, heat, pressure, and chemical bonds in ways that batteries simply cannot match.
Explainers Physics & EngineeringCATL's Qilin Condensed Battery achieves 350 Wh/kg, the highest energy density ever for a mass-produced EV cell. Here's what that record means, how it compares to competitors, and why your car's pack still lands at half that number.
Explainers Physics & EngineeringIntelligence agencies knew within weeks who launched NotPetya. The eight-month gap before public attribution reveals the minefield where technical certainty meets political calculation and international law demands evidence classified files cannot provide.
Digital Privacy ExplainersA single Dutch company controls 100% of the EUV lithography machines required to manufacture advanced chips. Built over 30 years with $8 billion in R&D and a global supplier network no competitor can replicate, ASML's monopoly has become the most consequential industrial chokepoint of the AI era.
Explainers Physics & EngineeringEinstein called it "spukhafte Fernwirkung," spooky action at a distance, and spent his final decades trying to disprove it. Ninety-one years later, the same phenomenon underpins quantum computers running entangled-qubit experiments at record scale.
Explainers Physics & EngineeringIn January 2026, the US loosened export licenses for AI chips to China while China simultaneously blocked those same chips at the border. Both governments now treat semiconductor export controls as industrial policy tools, accelerating the split of global technology into two incompatible systems.
ExplainersNations are racing to build sovereign AI infrastructure, pouring over $1 trillion into GPU clusters and data centers to escape American tech dependency. But with 90% of global AI compute concentrated in just two countries, the entire premise may be an expensive illusion.
Artificial Intelligence ExplainersAfter 115 years of research, the room-temperature superconductor remains physics' most tantalizing impossibility. The underlying physics explains why: fundamental trade-offs between the mechanisms that enable superconductivity work against each other as temperatures rise.
Explainers Physics & EngineeringResearchers just set a record by entangling 75 qubits on IBM hardware, but fundamental noise limits impose hard mathematical constraints on how far quantum entanglement can scale without error correction.
Explainers Physics & EngineeringThree neural mechanisms explain why synchronized ritual bonds strangers into cooperative groups: self-other merging, endorphin release, and inter-brain theta synchronization. Research spanning 40,000 years reveals how repetition transforms individual brains into collective minds.
