Redefining the second: Optical atomic clock achieves record precision in comparative measurements
A new In+/Yb+ crystal clock ion trap in a vacuum chamber. Credit: PTB The next generation of atomic clocks “keep time” at laser frequencies. This is about 100,000 times faster than the microwave frequency of cesium clocks, which currently generate seconds. These optical clocks are still being evaluated, but some are already 100 times more accurate than cesium clocks. They…

High-speed control technique enables record fidelity in superconducting qubits
In the artist’s impression of a recent MIT experiment, the sphere in the center represents a qubit, illuminated by two control signals: electric charge (blue) and magnetic flux (purple). These control signals are designed to combine to produce circularly polarized microwaves that are not affected by counter-rotation effects. The signals consist of repeating waveforms and represent the similarity of control…

Cape Cod dolphin strandings in worst year on record, scientists searching for answers
In this image provided by the International Fund for Animal Welfare, two dolphins are stranded along Ellis Landing in Brewster, Massachusetts, on November 9, 2024. An unprecedentedly bad year for dolphins on Cape Cod’s beaches may have something to do with the changing environment caused by rising ocean temperatures. Scientists said they hope to improve the availability of food for…
