Cold plasma looks like the glow from the “Star Wars” blue lightsaber but this beam of energy, made of electrons that change polarity at micro-second or nanosecond speeds, could help bones heal faster, according to a study published August 11th in the Journal of Tissue Engineering and Regenerative Medicine.

Most people interact with plasma every day. It’s in our TVs, fluorescent lights, lightning, the aurora borealis, and the sun. However, these are all examples of hot or “thermal” plasmas. Since the discovery of cold plasma, about 20 years ago, it has been used in agriculture to sterilize the surface of fruit without damaging the delicate edibles. More recently, scientists have been performing experiments treating living animal cells and tissues with cold plasma to learn more about its potential applications in medicine.

“We’ve previously studied how different applications of cold plasma can either directly kill cells, such as in skin cancer, or help them grow, as in developing bones. In this study, we asked how cold plasma would affect the area surrounding cells, known as the extracellular matrix,” says lead author Theresa Freeman, Ph.D., Associate Professor in the Department of Orthopedic Surgery in the Sidney Kimmel Medical College at Thomas Jefferson University. The extracellular matrix around cells is made of collagen and other proteins that interact with the cells and can influence their growth and behavior. For example, the extracellular matrix can either promote or inhibit bone formation or cancer cell growth and metastasis.

While bullet-proof body armor does tend to be thick and heavy, that may no longer be the case if research being conducted at The City University of New York bears fruit. Led by Prof. Elisa Riedo, scientists there have determined that two layers of stacked graphene can harden to a diamond-like consistency upon impact.

For those who don’t know, graphene is made up of carbon atoms linked together in a honeycomb pattern, and it takes the form of one-atom-thick sheets. Among various other claims to fame, it is the world’s strongest material.

Known as diamene, the new material is made up of just two sheets of graphene, upon a silicon carbide substrate. It is described as being as light and flexible as foil – in its regular state, that is. When sudden mechanical pressure is applied at room temperature, though, it temporarily becomes harder than bulk diamond.

In Brief

• A team of engineers at Brigham Young University have designed a bulletproof shield prototype that is inspired by origami.
• This new prototype is much lighter weight than previous models and could prove extremely useful in the field.

A new origami-inspired bulletproof shield prototype that can withstand shots fired from 9mm, .357 Magnum, and .44 Magnum pistols was created by a team of engineers from Brigham Young University (BYU).

Most bulletproof shields or barriers weigh almost 100 pounds, making them difficult to use and transport. A lightweight version would a useful alternative. Weighing only 55 pounds (25 kilograms), this new shield is made up of 12 layers of Kevlar with an aluminum core, and it is so light it can be folded.

Foam armor for the future.

In the George Lucas classic Star Wars, hero Luke Skywalker’s arm is severed and amputated during a lightsaber fight and consequently fitted with a bionic arm that he can use as if it were his own limb. At the time the script was written, such a remedy was pure science fiction; however, the ability to manufacture bionic arms that have the functionality and even feel of a natural limb is becoming very real, with goals of launching a prototype as soon as 2009. Already, primates have been trained to feed themselves using a robotic arm merely by thinking about it, while brain sensors have been picking up their brain-signal patterns since 2003. The time has come for implementing this technology on paralyzed human patients and amputees. This article will provide a brief explanation of the technology, its current status, and the potential future it holds.

This 3D-printable custom lightsaber is truly a thing of beauty. Here’s how you can make your own.

Scientists have just found a way to make use of plasma, the fourth state of matter, to improve bone development. Using cold fusion, researchers were able to initiate increased bone growth.

It is a bit ironic that plasma is the least known state of matter, when in fact it is the most abundant in the universe. It is found in our Sun and all other stars, lightning, in our TVs, fluorescent light, and neon signs, and (purportedly) even in our favorite fictional weapon in the Star Wars universe, the lightsaber.

Plasma can be classified according to the degree of ionization, temperature, etc, but whatever form it may take, plasma has been used in various fields, such as in spacecraft propulsion, agriculture, and quite recently, in medicine.
