Larry Ellison, co-founder, executive chairman, and CTO of Oracle Corporation, has become one of the richest people in the world—with a net worth that surged to around $390 billion in 2025, largely tied to his ~40% stake in Oracle.

Nicolás Maduro, leader of the United Socialist Party of Venezuela (PSUV) and president of Venezuela since 2013, ascended from bus driver and union leader to the top of the Chávez-era “Bolivarian” movement. His early election victory followed the death of Hugo Chávez with a narrow margin.

Gyotaku (魚拓), meaning “fish impression,” is a traditional Japanese art form that originated in the mid-19th century as a method for fishermen to record their catches before photography was available.

The diving bell spider (argyroneta aquatica) is the only known spider species that lives almost entirely underwater, inhabiting freshwater ponds and slow-moving streams across Europe and northern Asia. It constructs a silk “diving bell,” a dome-shaped web anchored to submerged vegetation.

In alloys and ferrites, engineers can precisely tune the Curie temperature through compositional changes, enabling temperature-sensitive magnetic switches and sensors.

Among the Banna people of Ethiopia’s Lower Omo Valley, the tradition of stilt-walking—executed by young men on slender wooden poles a few metres high—is both a practical skill and a deeply symbolic rite of passage.

Single-Photon Avalanche Diode (SPAD) sensors are ultra-sensitive semiconductor devices capable of detecting individual photons with picosecond temporal precision, making them invaluable for imaging phenomena at extremely fast timescales.

Over centuries, soil would rebuild from decomposed organic matter, reestablishing a functional ecosystem. Metals would corrode, plastics photodegrade, and concrete crumble, gradually buried beneath layers of vegetation and sediment as the biosphere erases humanity’s architectural footprint.

The UK’s developing digital identity system is structured around the Digital Identity and Attributes Trust Framework (DIATF), administered by the Office for Digital Identities and Attributes (OfDIA), which certifies organizations that meet strict technical, security, and privacy standards.

The traditional Afghan practice of Kangina—a centuries-old method for preserving grapes—originated in the arid highlands of central Afghanistan, particularly in provinces like Kandahar and Ghazni, where viticulture has thrived since pre-Islamic times.

Walking floors in trailer truck beds are engineered systems consisting of a series of parallel, slatted aluminum or steel panels that move in a precise, sequenced pattern to automate the loading and unloading of bulk materials without tipping the trailer.

Across the African Sahel, demi-lune (half-moon) rainwater-harvesting structures have become a cornerstone of landscape restoration, contributing—often together with other soil-and-water conservation measures—to the rehabilitation of hundreds of thousands of hectares.

A Boy and His Atom, created by IBM Research in 2013, is the world’s smallest stop-motion film, made by manipulating individual atoms to tell a short story. Scientists at IBM’s Almaden Research Center in San Jose used a scanning tunneling microscope (STM) operating in ultra-high vacuum.
