The replication crisis refers to the widespread difficulty in reproducing published scientific findings when independent researchers retest them using similar methods. The issue is most extensively documented in psychology but extends to medicine, biology, ecology, and evolutionary biology.

On October 21, 2026, OpenAI and Google Cloud jointly announced a partnership to bring OpenAI's frontier AI models and its Codex coding agent into Google Cloud's Model Garden. Google Cloud customers will be able to purchase these models through the Google Cloud Marketplace, and enterprises with existing Google Cloud spending commitments can apply those commitments toward OpenAI model purchases.

As Anthropic and OpenAI approach potential public listings, both companies are developing mechanisms to distribute portions of AI-generated wealth beyond founders, employees, and private investors.

Randomized controlled trials (RCTs) address the confounding problem inherent in observational research by assigning participants to treatment or control groups through a random process rather than by clinical judgment, patient preference, or prognosis.

Biomarkers such as blood glucose, LDL cholesterol, and blood pressure are measurable indicators that correlate with disease risk at the population level, but they rarely function as definitive predictors for any given individual.

Healthcare systems globally face a structural tension between prevention and treatment. Prevention interventions — including vaccination, sanitation, and screening — aim to stop disease before it occurs, generating population-wide gains.

The immune system faces a fundamental challenge: it must mount aggressive responses against pathogens while leaving the body's own tissues unharmed. This is achieved through immunological tolerance, a multi-layered process that begins during lymphocyte development and continues throughout life.

The 19th century witnessed a fundamental paradigm shift in medicine and public health, moving from miasma theory — which attributed diseases like cholera and plague to noxious "bad air" emanating from rotting organic matter — to germ theory, which established that specific microorganisms cause specific diseases.
