Modern humans have populated Europe for more than 45,000 years. However, our knowledge of the genetic relatedness and structure of ancient hunter-gatherers is limited, owing to the scarceness and poor preservation of human remains from that period. In new research, scientists from the University of Tübingen, the Max Planck Institute for Evolutionary Anthropology and elsewhere analyzed 356 ancient hunter-gatherer genomes, including new genomic data...

Differences between 3D, 2D, and 1D corrosion: (a) schematic drawing of a typical bulk bicontinuous dealloying corrosion morphology; (b) schematic drawing of a typical pitting corrosion morphology with the volume set as transparent; the grain boundaries (GBs) were not displayed because both intergranular and intragranular pitting can occur; (c) schematic drawing of a typical intergranular corrosion morphology with the volume set as opaque; the sides of the cube display the cross-sectional views; (d) schematic drawing of 1D wormhole corrosion in a polycrystalline material; the upper half is a cross-sectional view showing discontinuous dots (i.e., voids filled by molten salt) along the GBs; the bottom half is a volumetric cutaway along the GBs where the 1D percolating network of tunnels on the grain surfaces is clearly shown in red; the dark blue color in (a) to (c) indicates free space such as cracks, voids, crevices etc., while the red color in (d) indicates wormholes filled with molten salt; (e) a representative false-colored SEM image showing the cross-section of Ni-20Cr after corrosion; (f) FIB-SEM 3D reconstruction of the volume shown in (e).

Left: a fully assembled quantum system at Google Quantum AI; prominently displayed is the dilution refrigerator in which the computations occur, the quantum processor and quantum-limited amplifiers installed at the bottom stage of the refrigerator, various cables connecting bottom to top, and control electronics of quantum computer in the back. Right: two generations of Sycamore processors fabricated by Google Quantum AI; each processor features two chips that are bonded together: a chip containing the quantum bits (qubits), and a chip containing the wiring between the qubits and the outside world; the latest generation of the Sycamore processor on the right is notably larger than previous generations, but also has several modifications to the qubits resulting in improved performance.
