Nanoengineers boost signals from fluorescent sensors

Fluorescent sensors, which can be used to label and image a wide variety of molecules, offer a unique glimpse inside living cells. However, they typically can only be used in cells grown in a lab dish or in tissues close ...

Why would someone fake a hate crime?

Set amidst a bitter, divisive U.S. presidential election and a steadily-growing Black Lives Matter movement, actor Jussie Smollett exploded onto center stage in early 2019 after claiming he was the target of a late-night ...

Bright prospects for OCT retinal scans at 30

Around the world, every second, someone gets a retinal OCT scan, typically as a routine portion of an eye exam. The high-resolution images obtained by OCT allow ophthalmologists to diagnose and monitor treatment for many ...

Matrix imaging: an innovation for improving ultrasound resolution

In conventional ultrasounds, variations in soft tissue structure distort ultrasound wavefronts. They blur the image and can hence prove detrimental to medical diagnosis. Researchers at the Institut Langevin (CNRS/ESPCI Paris-PSL)1 ...
