MIT physicists improved the stability of optical atomic clocks by reducing “quantum noise” — a fundamental measurement limitation. The work could enable more precise, portable optical atomic clocks that track even tinier intervals of time, up to 100 trillion times per second.
A National Science Foundation grant will support Anne Brown’s goal to enhance the technical and practical data science skills of students studying molecular bioscience.
Researchers have improved the ability of wearable health devices to accurately detect when a patient is coughing, making it easier to monitor chronic health conditions and predict health risks such as asthma attacks. The advance is significant because cough-detection technologies have historically struggled to distinguish the sound of coughing from the sound of speech and nonverbal human noises.
