brought the philosophical exploration of quantum mechanics back into
June 13, 2012
A single sheet of paper is easy to tear, but why, then, do crumpled balls of newspaper work as cushioning in packing boxes? Physicists are studying this unique architecture that maximizes the inherent strength of paper.
June 06, 2012
Jim Ottaviani writes comic books (or graphic novels) about famous scientists including Richard Feynman, Niels Bohr, and those involved in the Manhattan Project.
NASA's Super Black Material
May 09, 2012
Light noise can make it difficult for Astronomers to see the objects they want to study. To help this, engineers have created a material that absorbs 99.8% of incoming light.
Curling Plant Roots
April 25, 2012
Jesse Silverberg is a physicists studying the way plant roots curl. His research contributes to a larger effort to understand how plants live and grow in unusual environments, like sandy or depleted soil. With the booming global population and the rising demand for food, this kind of research could find its way to your refrigerator very soon.
Naming the Elements

Soft robots are robots controlled by humans but made of materials that are soft. These robots are so gentle, they can even pick up a mouse.
Physics of Curly Hair
March 07, 2012
Did you know that there is a lot of physics that goes into making
animated hair look realistic? Today we chat with MIT graduate student
Jay Miller who studies how a single hair curls. But this research goes
way beyond animation; it turns out you can apply these same principles
to a whole bunch of stuff, like the flagella on bacteria and very long
Butterlfly IR sensors
February 22, 2012
The Morpho Sulkowsky butterfly uses its flashy iridescent wings to
attract attention, but humans could use those wings in applications
ranging from homeland security to medical imaging. Researchers at the
General Electric Global Research Center attached carbon nanotubes to
real Morpho butterfly wings, and used the resulting structures as
infrared (IR) light sensors, which have applications in medicine,
science, environmental sustainability and the military, to name a few.
Self Organizing Patterns
December 14, 2011
Researchers have found a way to hide secrete messages inside
self-organizing patterns. Self-organizing patterns include zebra
stripes, flocks of birds, and termite colonies, to name a few. These
examples might seem biological, but it is physicists who study the
science of self organizing patterns -- and sometimes hide top secret
messages in them.
