Scientists have measured the speed of quantum entanglement for the first time using attosecond techniques, providing new insight into how entangled particles interact and deepening our understanding of fundamental quantum behavior. #Quantum #QuantumComputing #technology #Science

Quantum entanglement speed is measured for the first time, and it's too fast to comprehend
Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how fast it happens.

Ancient DNA reveals the prehistory of the Uralic and Yeniseian peoples - Nature
Genome-wide sequencing of 180 ancient individuals shows a continuous gradient of ancestry in Early-to-Mid-Holocene hunter-gatherers from the Baltic to the Transbaikal region and distinct contemporaneous groups in Northeast Siberia, and provides insights into the origins of modern Uralic and Yeniseian speakers.
