Light and sound gauge the temperature of deep tissues

Measuring a fever is usually pretty simple: place a thermometer under a patient's tongue and get an accurate temperature reading within 30 seconds. But that simplicity does not translate when it comes to measuring the temperatures ...

New progress toward chip-based ghost imaging

For the first time, researchers have shown that the non-conventional imaging method known as ghost imaging can be performed using a low-cost, chip-based light-illuminating device. This important step toward chip-based ghost ...

Teaching AI to learn from non-experts

Today my IBM team and my colleagues at the UCSF Gartner lab reported in Nature Methods an innovative approach to generating datasets from non-experts and using them for training in machine learning. Our approach is designed ...

Researchers develop new ultra-fast 3D microscope

A new microscope can capture 3-D images of live organisms in real time. It's called the QIs-scope, an innovation from a spinoff of Universidad Carlos III de Madrid (UC3M), 4D Nature. The microscope can be used in biomedical ...

Researchers seek atomistic insights into ferroelectric materials

At first glance, biomedical imaging devices, cell phones, and radio telescopes may not seem to have much in common, but they are all examples of technologies that can benefit from certain types of relaxor ferroelectrics—ceramics ...
