NASA’s Artemis II returned safely to Earth on Friday, with its four astronauts splashing down about 50 miles off the coast of San Diego after a roughly 10-day journey around the moon. The first crewed mission beyond Earth’s orbit since 1972. The Orion spacecraft reentered the atmosphere at speeds near 25,000 miles per hour, facing temperatures of up to 5,000°F during descent. The landing marks a key milestone for NASA, particularly after concerns over the capsule’s heat shield. An earlier version used on Artemis I in 2022 showed unexpected wear on reentry, prompting engineers to adjust Artemis II’s trajectory to reduce thermal stress. With the mission now complete, NASA will shift focus to Artemis III, scheduled for 2027, which will test lunar landing systems in orbit before a planned human return to the moon as early as 2028.

True Spies
Cribs, Codes And Cairo
How do you break a code no one else can read?
Emily Anderson spent much of her life making sense of things other people could not. In public, she was known as a brilliant scholar who translated the letters of Mozart and Beethoven. In private, she was one of Britain’s most gifted codebreakers, serving through both world wars and mastering the kind of linguistic puzzles that could shape the course of history.
Recruited during World War I for her exceptional German and French, Anderson joined the Army’s codebreaking unit in London, where she helped intercept and unravel diplomatic messages sent by Britain’s enemies. She quickly proved herself not just as a decoder, but as a “book builder”: the rare specialist who could reverse-engineer the structure of an entire cipher system. By the war’s end, she was already regarded as one of the finest cryptanalysts in British intelligence.
She stayed on, joining the Government Code and Cypher School and eventually leading its Italian diplomatic section. By World War II, that work took on new urgency. Anderson and her team tracked Italian intentions as Europe slid back into war, before she was sent into the high-stakes world of wartime Cairo, where codebreakers worked under threat while Rommel’s forces advanced across North Africa.
Join historian Jackie Ui Chionna in this week’s podcast selection, 'Cribs, Codes And Cairo', to follow one of Britain’s greatest codebreakers from Bletchley Park to the brink of war.

A fresh attempt to unmask Bitcoin’s creator has put British cryptographer and cypherpunk Adam Back in the spotlight, after NYT investigative journalist John Carreyrou suggested he may be the figure behind the pseudonym Satoshi Nakamoto. The claim, which Back has denied, draws on analysis of emails revealed during a separate legal case, along with his long-standing ties to the cypherpunk movement: an early group advocating for privacy-focused digital systems.
Bitcoin first appeared in 2009 with a now-famous white paper outlining a decentralized currency free from government control. Despite years of speculation, Nakamoto’s identity remains unknown, with more than 100 individuals named as potential candidates. One high-profile claimant, Craig Wright, was later discredited and convicted of fraud after attempting to prove he was the creator.
The mystery persists in part because Nakamoto disappeared soon after launching the project, leaving behind a system that now underpins a trillion-dollar crypto market. Whoever they are, they’re believed to control roughly $70 billion in bitcoin. Wealth that has never been moved...

Self-Cleaning Sails
How does a harbor landmark stay bright white in sea air?
The Sydney Opera House sits directly on the waterfront, where salt spray, exhaust, and city pollution would quickly stain a typical façade. But its distinctive shells weren’t built to fight that environment with constant maintenance; they were designed to resist the elements.
Architect Jørn Utzon worked with Swedish manufacturer Höganäs to develop a custom outer layer made from over a million interlocking ceramic tiles. Instead of a flat surface, the tiles were arranged in a subtle pattern and finished with a specialized glaze that interacts with water in a precise way. The coating creates an ultra-smooth surface at a microscopic level, making it difficult for dirt, salt, and pollution to stick. When rain passes over the structure, water forms beads that roll across the tiles, lifting debris as they move.

The US fertility rate fell to a record low in 2025, according to new data from the Centers for Disease Control and Prevention, continuing a nearly two-decade decline. Births dropped to 53.1 per 1,000 women ages 15 to 44, down from 53.8 the year before, with total births falling 1% to just over 3.6 million.
The shift reflects a steady change in whether and when people choose to have children. Birth rates among younger women continued their sharp decline, falling 7% overall, with both younger and older teen groups reaching record lows. At the same time, births among women ages 30 to 34 rose slightly, pointing to a longer-term trend of delayed parenthood. Since 2007, the overall US birth rate has dropped by roughly 23%.
The pattern mirrors a broader global trend. Many countries now fall below the replacement level of about 2.1 children per woman, the threshold estimated to maintain stable population levels. Researchers link the shift to a mix of economic pressures, changing social norms, and greater access to education and contraception.
