The Top Tech Briefs Stories of 2017

With another year of Tech Briefs almost in the books, it's time to look at our most-read news articles of 2017.

Top stories included a look back at the life of Robert Goddard, and a look forward to...

Using a narrow band of microwave frequencies, researchers at Duke University found a new way to see on the other side of the wall.
A Tech Briefs reader asks our expert to compare three 3D-printing techniques.

A vortex in the atmosphere can churn with enough power to create a typhoon. But more subtle vortices form constantly in nature. Many of them are too small to be seen with the naked eye....

Printing a Better Actuator

One technology uses magnetic fields to generate mechanical work. The other enhances the magnetic properties of 3D-printed materials. Combined, they could lead to efficient, economical production of magnetic...

Question of the Week
Would you use "Printed Wi-Fi?"

This week, Tech Briefs TV featured an additive-manufacturing technology from the University of Washington.

During the historic Apollo 11 mission, the astronauts, mission control specialists, and back-room support staff did plenty of communicating. The University of Texas at Dallas launched a project to make all of the moon-mission audio accessible.

The “Internet of Things” links a variety of devices, from computers and industrial machines to heart monitors and robots. The interconnection also leads to some...

Imagine a tire that could heal after being punctured or a rubber band that never snapped.
