Study Links iPhone Adoption to Declining US Birth Rates
A National Bureau of Economic Research study by Caitlin K. Myers and Ezekiel Hooper found that iPhone adoption correlates with significant declines in US fertility rates, particularly among women aged 15-24. The researchers used AT&T's initial exclusive coverage of the iPhone in 2007 as a natural experiment to isolate the smartphone's effect from other economic factors. The study suggests smartphones may reduce in-person interactions and sexual frequency, potentially explaining 33-52% of the overall fertility decline among women aged 15-44.
Researchers Caitlin K. Myers and Ezekiel Hooper from the National Bureau of Economic Research investigated the relationship between iPhone adoption and the 22% decline in US fertility rates since 2007. Using AT&T's initial exclusive distribution of the iPhone as a natural experiment, they compared fertility trends in areas with early smartphone access to those without, controlling for other commonly cited factors like economic conditions, contraceptive availability, and childcare costs. The study found that iPhone access reduced births by 4.5-8.0% among women aged 15-19 and 3.2-6.6% among women aged 20-24, with smaller but statistically significant declines in older age groups. The researchers attribute these effects to smartphones reducing in-person interactions, increasing pornography consumption, and decreasing sexual frequency. Overall, the diffusion of the iPhone explains approximately 33-52% of the fertility decline among women aged 15-44.
How coverage differed
The Daily Wire (right-leaning) frames the finding as evidence of a "fertility crisis" and emphasizes concerns about population decline, while the Times of India (center) presents the research more neutrally as a "surprising study" without editorializing about societal implications.

New AI Framework Improves Evidence-Based Analysis for Muon Collider Research
Researchers have developed an AI system called agentic hybrid RAG that combines retrieval and reasoning techniques to help scientists find and verify evidence in muon collider research literature. The framework integrates both keyword-based and semantic search methods with AI reasoning to decompose complex queries and synthesize answers. This work addresses a growing need in high-energy physics for AI-assisted tools that can reliably navigate rapidly expanding scientific literature.
NASA Announces Four-Astronaut Crew for Artemis III Moon Mission
NASA named three U.S. astronauts and one Italian astronaut from the European Space Agency as the crew for Artemis III, scheduled to launch in 2027. The mission will conduct a docking demonstration in Earth's orbit and test moon landers from SpaceX and Blue Origin. The crew includes a veteran test pilot, a record-holder for longest U.S. spaceflight, and a first-time space flyer.
Rare Great White shark filmed in Mediterranean Sea between Tunisia and Sicily
A volunteer diver captured rare footage of a Great White shark in the Mediterranean Sea in May while working to document ghost fishing nets. The sighting is significant because Great Whites are thought to be near extinction in the Mediterranean due to overfishing. Conservationists hope the discovery will prompt governments to establish marine protected areas in the region.
