At the smallest scales, materials are never entirely still. Atoms in a crystal continuously vibrate around their resting positions, and some of these vibrations, called phonons, have well-defined energies that can interact with light. Normally, light and a material vibration […]
Water is H₂O. Few scientific formulas look more familiar, more compact, or more final. Two atoms of hydrogen, one of oxygen: the phrase seems to say what water really is beneath the shifting appearances of ice, vapour, rain, rivers and […]

A giant volcanic eruption acted a little like Vesuvius, but across an entire landscape in the Andes, burying the terrain beneath it and preserving information that would otherwise have been lost to erosion and deformation. Recently, the researchers looked at […]

Nickel disulfide, NiS₂, is an unusual material. Its interior behaves as an electrical insulator, blocking the flow of current, while certain parts of its surface conduct electricity freely. This contradiction has puzzled physicists for decades, and a recent study offers […]
Acute myeloid leukemia (AML) with t(6;9)/DEK::NUP214 is recognized as a separate entity in the World Health Organization classification of myeloid neoplasms, accounting for 1% of all AML cases and characterized by a high relapse rate and young age at diagnosis […]
As we saw in our last entry, we must grant Gabriel that he does not conceive of the spirit and spiritual as an “immortal soul” or any similar ghostlike entity, but rather as something grounded in human thought—more specifically, in […]

When we study solid-state physics, we usually begin with crystals. In a crystal, atoms repeat in a strict and regular pattern, much like tiles on a bathroom floor. Because every small region looks the same as every other, electrons move […]
Plutonium has captured the attention of scientists since its discovery in the early 1940s. This enigmatic element has an important role to play in emerging energy technologies like nuclear batteries and reactors, but it also has complicated electronic behavior that […]
Author: Daryl Janzen, Observatory Manager and Instructor, Astronomy, University of Saskatchewan Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time — the interwoven fabric of space and time at the heart of Albert Einstein’s […]
By 1800, water had already changed once. It was no longer one of nature’s simple terms, but a compound of hydrogen and oxygen (see Is Water H₂O? (1) From Element to Compound). The new chemistry had a powerful account of […]
Author: Shireen Kassam, Visiting Professor, Health and Wellbeing Research Group, University of Winchester and Dagfinn Aune, Research Fellow, School of Public Health, Imperial College London More than 1.4 billion people worldwide live with high blood pressure (hypertension). It’s the single […]
Take a walk in London’s Trafalgar Square this summer and wilting under the heat will be all sorts of body sizes, some tall, some short: a real mix of sizes. Picking just two from the crowd to represent the whole […]
Take a glass of water. Nothing about it seems to ask for a theory. It has no colour worth naming, no dramatic smell, no visible architecture. It runs, freezes, boils, evaporates, dissolves, erodes, circulates and nourishes. It belongs to weather […]
Author: Richard de Grijs, Professor of Astrophysics, Macquarie University How do you explore a place where the Sun never shines? China’s space programme will soon embark on one of the most innovative lunar exploration missions in recent years. We’ve known […]
