Ancient DNA reveals how women helped transform prehistoric Europe

Nearly 5,000 years ago, respiratory infections, possibly including tuberculosis, were ravaging the children buried at Camino del Molino (CMOL), Spain. The massive circular burial cave carved into rock is Europe's largest Copper Age mass burial, containing over 1,300 individuals, and has been the subject of years of excavation and analysis.

A research team from HKU Engineering has pioneered a fundamentally new imaging strategy known as AIMED (Arbitrary illumination microscopy with encoded depth), which utilizes a sub-sampling approach. By integrating innovations in axial optical encoding with advanced computational image reconstruction, the AIMED technology enables a substantial increase in 3D imaging speed while enhancing photon safety, all with minimal additional system complexity. This breakthrough demonstrates significant advan

Cosmic rays seen at Earth show a wide range of particle energies, from 107 electron-volts (eV) to more than 1020 eV, the latter being about the same as the kinetic energy of a 450 gram football (soccer ball) being kicked across the pitch at about 8 meters per second. A plot of cosmic ray energies from the Milky Way galaxy often shows a fair amount of what scientists might call "structure"—interesting deviations from the underlying trend called "knees" and "ankles" that indicate new processes or

For the past several years, Penn State geoscientist Sarah Ivory and her students have been among a team of scientists scaling the East African Rwenzori Mountains, collecting sediment core samples from lakes formed at the end of the last ice age as glaciers began receding in the region some 12,000 years ago.
