Kwabena Boahen Asare was determined to conquer his fear of public speaking after landing a research placement that required him to give weekly presentations.
Some are hopeful, but others worry that Claudia Sheinbaum Pardo will follow in her controversial predecessor’s footsteps rather than stand up for science.
Contractile forces at the surface of cells of early human embryos bring the cells together. When these forces are absent, the embryo will not develop further. ‘Weak’ cells do not produce these forces and cannot contribute to the embryo. These observations should influence clinical choices during assisted reproductive-technology procedures.
In this work, stable trapping of a two-dimensional Wigner crystal of above 500 ions is achieved, and the quantum simulation of 300 ions with individual state detection demonstrated.
A modular quantum system-on-chip architecture integrates thousands of individually addressable spin qubits in two-dimensional quantum microchiplet arrays into an integrated circuit designed for cryogenic control, supporting full connectivity for quantum memory arrays across spin–photon channels.
