For more than three decades, the phrase “cold fusion” has carried a whiff of promise as well as scandal. In 1989, chemists Martin Fleischmann and Stanley Pons announced that simple tabletop experiments with palladium electrodes in heavy water seemed to produce more heat than chemistry could explain. If true, this meant nuclear fusion, an energy…

Managing traffic in rapidly growing cities remains one of the biggest challenges for urban planners worldwide. Traffic signal lights and other network control systems are crucial for preventing urban chaos, yet testing the effectiveness of new traffic management algorithms has remained a time-consuming and resource-intensive task. In a step towards smarter urban mobility, researchers at…

A lifelong teacher and researcher Born in Cranleigh, Surrey, England in 1877, G.H. Hardy came from a teaching family. Hardy’s first names were Godfrey Harold, but he never really used them, preferring the initials “G.H.” instead. Hardy’s father was an administrator and art master at Cranleigh School, while his mother was a senior mistress at…
In the race to make quantum computers practical, scientists have found themselves drawn to some of the strangest ideas in physics. Few are stranger — but also more promising — than the notion of using particles that are their own antiparticles to store and manipulate information. This is the concept behind Majorana particles. In the…
