Health-monitoring apps can help people manage chronic diseases or stay on track with fitness goals, using nothing more than a smartphone. However, these apps can be slow and energy-inefficient because the vast machine-learning models that power them
A new chip can efficiently accelerate machine-learning workloads on edge devices like smartphones while protecting sensitive user data from two common types of attacks — side-channel attacks and bus-probing attacks.
Making nanoscale patterns in “scintillator” materials that convert X-rays into light could allow a tenfold signal enhancement for medical or industrial imaging, MIT researchers report. This method might lead to improvements in medical X-rays or CT scans, to reduce dose exposure and improve image quality.
Scintillators are materials that emit light when bombarded with high-energy particles or X-rays. In medical or dental X-ray systems, they convert incoming
