Researchers at the University of Copenhagen found that a signaling mechanism in the cells’ ‘antennae’ may help explain why some fetuses develop disease in both the heart and other organs. About two of every 100 babies worldwide are born with congenital heart disease, but the biological processes responsible for these conditions are not fully understood. […]
A Major Dementia Study Finds Striking Differences After Age 90
Reaching 90 without dementia may feel like clearing the final hurdle. But the risk does not necessarily end there. Dementia risk does not disappear after age 90. Even among people who reach their 10th decade without cognitive symptoms, the likelihood of developing the condition can vary substantially by sex, race, ethnicity, and genetics, according to […]
Scientists Say Eating Less Protein May Help You Live Longer
The protein boom may be pushing many people to consume far more than their bodies need, and new research suggests that excess could come at a hidden cost. Protein has become one of the food industry’s favorite selling points. It is added to cereal, coffee, snack bars, desserts, and even water, often with the suggestion […]
Democracy Has a Math Problem No Country Can Fully Solve
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 […]
