The hippocampus is a crucial part of the brain that plays a role in memory and learning, especially in remembering directions and locations. New research from the University of Chicago shows how this small, curved structure reorganizes its activity depending on whether a situation matches people’s memories and expectations.
When we watch videos or ask AI questions, enormous amounts of data are constantly moving inside computers. In particular, data centers that support AI must process and transfer vast amounts of data at very high speeds. However, current computers have a fundamental limitation: the place where calculations are performed and the place where data is stored are physically separated.
Because of this, data has to travel back and forth many times within a chip. This repeated movement takes time and consumes energy, creating a bottleneck that limits both speed and efficiency.
A study published in Azania: Archaeological Research in Africa sheds new light on the westward spread of pearl millet (Pennisetum glaucum) agriculture in prehistoric West Africa. A recent survey documented its earliest known occurrence in the Lac de Guiers basin of Northern Senegal, around AD 200, coinciding with increasing aridification, which may have driven the expansion of dryland farming communities westward.
The findings are significant as they help illuminate the westward spread of domesticated crops and mark the first time pearl millet spread beyond the Middle Senegal valley.
Scientists confirmed that an exoplanet mirrors its star’s chemical makeup, validating a core assumption about how planets form and evolve.
The US Air Forces Central (USAFCENT), a component of US Central Command (CENTCOM), has placed an order worth over $9m with US-based drone manufacturer Skydio for the supply of Skydio Dock and X10 systems.
The drones and infrastructure will be used to secure US airbases in the Middle East as part of one of the largest deployments of autonomous drone security systems by the US Air Force (USAF) for international base protection.
