11,000-Year-Old Grains Reveal a Surprise About the Origins of Agriculture

A new integrated isotope study suggests that early increases in cereal grain size were driven by growing conditions rather than human selection. About 11,000 years ago, communities across southwest Asia began cultivating wild cereals, legumes, and fruit-bearing plants as they increasingly produced their own food. Over thousands of years, these practices reshaped hunter-gatherer lifeways and […]

Lost Vatican Letter Recasts 1066 as a Holy War Against “Followers of Satan”

A lost papal letter suggests King Harold’s support for a rival pope may have helped turn the Norman Conquest into part of a wider European power struggle. For generations, the story of 1066 has seemed straightforward: a disputed crown, an invading duke, and a decisive battle that ended Anglo-Saxon rule in England. But new research […]

This Common Gut-Bacteria Compound May Be Linked to Alzheimer’s Disease

Gut bacteria produce a common compound called imidazole propionate, and a study found that higher levels are associated with dementia related changes in the brain. A molecule made by gut bacteria could help explain why changes in the intestinal microbiome are connected to Alzheimer’s disease. Researchers report that higher levels of imidazole propionate, or ImP, […]

This Common Type of Medication Is Linked to Slower Cognitive Decline

People with atrial fibrillation and Alzheimer’s disease who received NOACs showed a modestly slower rate of cognitive decline. For people living with both Alzheimer’s disease and atrial fibrillation, the type of blood-thinning medication they receive may be linked to how quickly their cognitive abilities decline. Research from Karolinska Institutet, published in the European Heart Journal, […]

Light Reveals the Hidden Quantum Motion Inside an Exotic Crystal

Optical measurements can reveal the hidden collective motion and quantum dynamics of electrons inside a Wigner crystal. In a Wigner crystal, electrons behave in an unusual way. Rather than moving independently, strongly interacting electrons confined to a two-dimensional plane can arrange themselves into a repeating lattice similar to the atoms in an ordinary crystal. Researchers […]
