How Do Hydraulic Brakes Work?

If you’ve ridden in a modern car, bus, truck, aircraft, or even on certain bicycles, you’ve used hydraulic brakes. You most certainly have used them, but do you know how they work? Find out with this quiz.

The Mechanics Behind Motion: Exploring Planetary Servo Gearboxes

While growing up, many of us were fascinated by watching gears turning, whether in bicycles, clocks or garbage trucks packing trash on the old rear-load machines. Today, gearing systems play a crucial role in machinery, transmitting power efficiently and reliably across a wide range of applications. Read on to learn more.

Robotic System for Assembly and Maintenance of Lightweight Reconfigurable Structures

Missions to the moon and other planets will require large-scale infrastructure that would benefit from autonomous assembly by robots without on-site human intervention. NASA Ames Research Center has developed a novel and efficient mobile bipedal robot system to construct low-mass, high precision, and largescale infrastructure. Read on to learn more.

This Self-Powered Device Can Detect Toxic Amines in Water

Researchers have built a self-powered device that detects toxic amines in water using electrochemiluminescence (ECL).

Knitting Machine Makes Solid 3D Objects

A new prototype of a knitting machine creates solid, knitted shapes, adding stitches in any direction — forward, backward, and diagonal — so users can construct a wide variety of shapes and add...

The Hidden Heroes of Hydrogen Flight: Sealing and Materials

In this sponsored episode of the Aerospace & Defense Technology podcast, Margaux Ningre-Coirier, Aerospace Sales and Market Development Manager at Omniseal Solutions, is the guest to analyze how advanced sealing solutions are becoming the hidden enablers of safe, efficient hydrogen-powered advanced air mobility (AAM).
