In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression and confusion – all of which worsened until her untimely death five years later. In […]
A few years ago, the chess website Chess.com temporarily banned US grandmaster Hans Niemann for playing chess moves online that the site suspected had been suggested to him by a computer program. It had reportedly previously banned his mentor Maxim Dlugy. And at the Sinquefield Cup earlier this month, world champion Magnus Carlsen resigned without […]
Astronomers once believed the Sun revolved around the Earth. In the 19th century, scientists thought the shape of a person’s skull could reveal their mental strengths or weaknesses.

This cancer is characterized by the rapid growth of immature myeloid precursors that occupy and alter the bone marrow (BM) niche where normal hematopoietic stems cells (HSCs) reside (the “niche” is the in vivo microenvironment where stem cells reside and receive […]

Every geography schoolbook has them: maps that look like today’s Earth, but not quite, since all continents are merged into a single supercontinent. Those maps were used to explain why dinosaurs in South America and Africa, or North America and Europe looked so alike. “Paleogeographic” reconstructions like these provide context to study the processes that […]
We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies – stars at their outer edges, far from the gravitational force of all the matter at their centre – were moving much faster […]
Most internet users are by now aware of the vulnerability of their personal data. When the news broke that tech companies misuse and manipulate our personal data, there was a widespread “techlash” against the corporate giants Facebook, Amazon and Google. The explicit motive for data harvesting is the prediction of consumer wants and needs. And […]
Now that the U.S. Supreme Court has given states final say over if and when abortions are legal, the political debates over abortion rights will intensify in legislatures and courthouses around the nation.
