Mathematics shows that every electoral system must compromise among proportionality, local representation, and parliament size. Denmark’s 2022 national election came down to a single seat, even though its proportional voting system was designed to make party representation closely match the vote. That outcome points to a deeper mathematical problem: no electoral system can always preserve […]
Cave Discovery Suggests Neanderthals and Modern Humans May Have Shared Culture
Modern humans and Neanderthals may have shared more than land and genes. They may have also shared culture. Modern humans and Neanderthals may have shared more than territory, tools, and genes. New evidence from a cave in southern Türkiye suggests the two groups may also have exchanged ideas and developed similar symbolic traditions over thousands […]
Scientists Discover a Hidden Way T Cells Attack Leukemia
T cells may use a previously unknown CD64-dependent pathway to attack acute myeloid leukemia. T cells are generally thought to identify cancer through a well-established molecular recognition system. Yet when researchers removed a key part of that system from acute myeloid leukemia (AML) cells, the immune cells continued killing them. The unexpected result led scientists […]

A Vegan Diet May Begin Changing Gene Activity in Just 4 Weeks
Changing what you eat may begin reshaping how your genes behave in as little as a few weeks, even though your DNA itself remains unchanged. In a randomized clinical trial, researchers found that healthy adults who followed a vegan diet for one month developed changes in chemical markers attached to their DNA. Compared with participants […]
Belly Fat and Low Vitamin D May More Than Double the Risk of Early Death
A study of more than 5,500 people suggests that monitoring hormone levels and managing weight may help reduce the risk of premature death. For adults over 50, excess abdominal fat and low vitamin D levels may form a particularly dangerous combination. A study of more than 5,500 people found that participants with both conditions had […]
Researchers Map the Hidden 3D Geometry of a Quantum Wavefunction
Physicists at Göttingen University imaged three-dimensional wave functions using a tabletop soft X-ray laser. An electron inside a molecule does not occupy one fixed point. Quantum mechanics instead describes it through a “wavefunction,” a mathematical map that gives the probabilities of properties such as position and momentum. Within molecules, these electron wavefunctions are known as […]
