Credit: Pixabay/CC0 Public Domain Space is an unnatural environment for humans. We can’t survive unprotected in a pure vacuum for more than two minutes. Getting to space involves being strapped to a barely contained chemical explosion. Since 1961, fewer than 700 people have been into space. Private space companies such as SpaceX and Blue Origin … Read more
California suffered a heat wave in early September. The 2024 northern summer saw the highest global temperatures on record, beating 2023’s high and making this year likely Earth’s hottest ever recorded, the EU’s climate monitor said Friday. The data from the Copernicus Climate Change Service followed a season of heat waves around the world that … Read more

As countries and industries increasingly turn to the oceans for economic growth, this study warns of the risk that current policies could deepen social inequalities … Read more
A formamide modification (yellow) to a therapeutic agent siRNA (blue) prevents siRNA to bind to non-target mRNA, which allows for treatment with less side effects. Credit: Reiko Matsushita Small interfering RNA (siRNA) drugs are a class of therapeutic agents that silence specific genes associated with inherited diseases. However, siRNA drugs have challenges because siRNAs often … Read more

by Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS The microsphere, levitated by the dual beam optical tweezer (green), is driven by the active optomechanical system (red) to generate nonlinear phonon lasers (colored waves). Meanwhile, the injected electrical signal, represented by the white lightning mark, acts as a simple but powerful … Read more
QSA All Personnel Meeting 2024. Credit: Berkeley Lab Before quantum computers can solve complex problems, researchers must develop technologies that manage larger numbers of qubits (the building blocks of quantum computers) for extended periods. Neutral atoms play an important role in this effort and are promising for quantum computing because they offer a stable, controllable, … Read more
Visualization of the structure of the level-3 many-hypercube code. Credit: Science Advances (2024). DOI: 10.1126/sciadv.adp6388 In work published in Science Advances, Hayato Goto from the RIKEN Center for Quantum Computing in Japan has proposed a new quantum error correction approach using what he calls “many-hypercube codes.” This approach, which turns out to have an elegant … Read more
