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 […]
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 […]
Researchers at Nagoya University have built a graphene nanoribbon that can switch which way it twists using a natural solvent. Graphene nanoribbons are thin ribbon-shaped structures made of fused carbon rings. Twisted or helical versions of these ribbons show promise […]
Arsenic contamination in drinking water poses a critical global public health hazard. Prolonged exposure to inorganic arsenic—predominantly present in groundwater as arsenate, where arsenic exists in its +5 oxidation state—can lead to severe dermatological lesions, cardiovascular diseases, and cancers. To […]
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 […]

One of the most popular versions today of the idea that there can be moral progress—in the sense that our values and moral standards can keep improving—is the claim, much in vogue now, that such progress takes the form of […]
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 […]

Author: Melissa Lee, Senior Lecturer, School of Mathematics, Monash University Some weeks ago, artificial intelligence company OpenAI announced ten advances in mathematics and computer science made with their as-yet unreleased model Astra. The discoveries cover a wide range of mathematical […]
