The structural components of advanced reactors such as the sodium fast reactor and the traveling wave nuclear reactor must be able to withstand the extreme levels of radioactivity from the fission…

Researchers have created highly focused pathways that can channel electricity through the atmosphere. It's not a new idea, Nikola Tesla worked on powering wireless lamps using electrostatic induction…

It’s true. Here’s my 555 Guituner circuit: go to 50 – 555 circuits web page on talkingelectronics.com and search for “guitar tuner” and you will find my circuit. Actually they’ve modified it slightly…

Laser physicists have found a way to make atomic-force microscope probes 20 times more sensitive, using laser beams to cool a nanowire probe to minus 265 degrees Celsius.  Atomic force…

If you've ever spent any time watching a gecko, you've been impressed by their uncanny ability to adhere to any surface - including upside down on ceilings.  A new study in the Journal of…

11 years ago, DARPA predicted that there was a physics-induced train wreck coming straight at the computer chip industry; the limits of what electricity and existing materials can do. Even then,…

You can easily build a Cartesian diver toy using an empty one liter soda bottle (with the label torn off), a ketchup packet, and tap water. You may want to have a few ketchup packets on hand and put…

Materials that are firmly bonded together with epoxy and other tough adhesives are ubiquitous in modern life — from crowns on teeth to modern composites used in construction. Yet it has proved…

There's a new wave of sound on the horizon carrying with it a broad scope of tantalizing potential applications, including advanced ultrasonic imaging and therapy, acoustic cloaking, and levitation…

If you have watched the NASA channel recently, you might have witnessed a series of experiments regarding flames.  On the surface, pardon the pun, it may have seemed like a minor thing, but how…
