1803: historians trace Balmis at sea. The Balmis Expedition left A Coruña, Spain, on November 30. Vaccinating children in succession kept the smallpox vaccine viable during the long voyage. Official correspondence from 1804 records uncertainty about departure and disagreements over food and lodging arrangements. It also raises issues about the children's care. Keeping a vaccine viable during transport is a separate question from how the children were treated. The article explains why training local medical workers and establishing vaccination boards mattered after the voyage: both were measures intended to keep vaccinations going. That separates the task of crossing an ocean with a viable vaccine from the task of maintaining a local vaccination system. For medical history researchers assessing the expedition, the account also keeps vaccine distribution distinct from the eradication of smallpox in 1980. Read the article for the documented chronology and those distinctions.

API teams assess Claude Opus 5.5 costs. Input and output rates are 20% lower than Opus 5, but actual spend depends on tokens and caching. Anthropic's 40% reduction in task costs is based on its evaluation, not a fixed saving for each workload. Published rates are a starting point for a budget; token usage and cache use shape the bill you pay. Standard pricing is $4 per million input tokens and $20 per million output tokens. Cache reads are $0.20 per million tokens, 60% lower than Opus 5. For a performance reference, Anthropic reports a Terminal-Bench 4.0 score of 66.4%, up from 52.3%. The roughly 85% reduction in attempts to bypass boundaries comes from a specific safety evaluation, not a claim about every deployment. If migrating an existing API, check the model name and inference and tool-calling settings. Read the comparison to weigh the reported results against your workload.

Renters see a 1,188,000-home goal. The public housing target spans 2026 to 2030, with 917,000 units in the Seoul metropolitan area. It is a supply target, not a count of homes people have moved into. The 1,188,000-unit target includes construction starts, purchase agreements and contracts. Reading it as the number of homes ready to occupy would give applicants the wrong basis for a housing decision. Universal public rental housing is being pursued to extend eligibility to the middle class. Figures of 180% to 200% of standard median income and rents at 70% to 80% of market rates were not confirmed move-in criteria at the time of the announcement. Income and asset caps and rents still need confirmation. Renters considering these projects can read the article to separate the supply goal from confirmed eligibility. Later policy announcements and each project's application notice are where to check the rules, rents and application dates.

Yen-exposed firms weigh costs. A weak yen can affect revenue and costs differently, even after Japanese rate hikes. After the September 2026 policy decisions, the U.S.-Japan rate gap was 2.50 to 2.75 percentage points. That gap helps explain why higher Japanese rates alone have not reversed yen weakness. A current account surplus may not prompt immediate yen buying when income earned overseas is reinvested there. The article separates that rate gap from the yen carry trade, which seeks returns from interest-rate differences but can lose money if the yen strengthens. It also explains the limits of currency intervention. For a business, the useful check is the currency of both revenue and costs, rather than the exchange rate alone. Businesses with yen-linked sales or purchases can use that distinction to assess their exposure. People buying yen with won should check both dollar-yen and won-dollar rates. Read the article for the full reasoning.

Before flooding, renters clear drains. Flood barriers must also be installed before flooding begins. If water enters a semi-basement or sewage backs up, evacuate before gathering belongings. The checks depend on the rental room. In a semi-basement, assess the entrance and the risk of sewer backflow. In a rooftop unit, check roof drainage and look for signs of leaks. That distinction helps renters focus on where water could enter their space. After flooding, a dry-looking exterior does not make electrical equipment safe to reuse. Arrange an electrical safety inspection. Once it is safe, photograph damage before restoration begins to record the affected area before work changes it. People renting semi-basement or rooftop rooms can read the article for the sequence of preventive checks, evacuation and post-flood steps.
