Made from a synthetic version of the highly-prized sapphire gemstone, new transparent armor is lighter, thinner and pulverizes bullets on impact.

Currently used by the military on powerful missile launchers and state-of-the-art fighter jets, the unusual transparent armor also has wide-ranging potential to protect troops on the battlefield.

Sapphire gems have long been sought after for their stunning blue beauty, but synthetic sapphires are prized for combat applications. The sapphire is harvested synthetically, producing pure sapphires that are transparent like glass — instead of the iconic blue.

Until this past year, consumer drones carried tiny ultralight cameras, but they just didn’t have the energy or the reserve to carry much else. They certainly could not deliver much of a product or payload. They flew for 15 minutes, lacked the capacity to carry excess weight, and had short range.

But market demand sparks innovation. Amazon and Domino’s Pizza are experimenting with drone delivery. The improvements needed to serve these needs are quickly bubbling down to unlicensed weekend pilots. Hexacopters with 4K cameras, gimbals and retracting landing gear are available for under $400. Tiny foldable drones with 720p cameras are available for $35. Some models don’t even need a pilot on a joystick. You can preprogram the flight path to reach any target using GPS, or you can guide them by making gestures with your hand. The drone actually looks back over its shoulder and responds to your hand-waving commands.

Handheld weapons that could set fire to targets from long distances are no longer confined to science fiction but a fact of life, according to researchers.

It wouldn’t be #MayTheFourth without some awesome Star Wars news.

The strange, cosmic reason our evolutionary path will look ever luckier the longer we survive.

I t was hard times for the bomber pilots that floated over Europe, their planes incinerating cities below, like birds of prey. Even as they turned the once-bustling streets beneath to howling firestorms, death had become a close companion to the crews of the Allied bombers as well. In fact, surviving a tour with the Bomber Command had become a virtual coin flip. While their munitions fell mutely from bomb bays, an upward sleet of fire from smoldering city grids and darkened farmland shot the planes out of the sky like clay pigeons. For recruits encountering the freshly empty bunk beds of dead airmen, morale was sapped before they could even get in the cockpit. Hoping to slow this attrition, Allied officers studied the pattern of bullet holes in returning aircraft for vulnerable parts to reinforce with armor.

Try a quick experiment: Take two flashlights into a dark room and shine them so that their light beams cross. Notice anything peculiar? The rather anticlimactic answer is, probably not. That’s because the individual photons that make up light do not interact. Instead, they simply pass each other by, like indifferent spirits in the night.

But what if light particles could be made to interact, attracting and repelling each other like atoms in ordinary matter? One tantalizing, albeit sci-fi possibility: light sabers — beams of light that can pull and push on each other, making for dazzling, epic confrontations. Or, in a more likely scenario, two beams of light could meet and merge into one single, luminous stream.

It may seem like such optical behavior would require bending the rules of physics, but in fact, scientists at MIT, Harvard University, and elsewhere have now demonstrated that photons can indeed be made to interact — an accomplishment that could open a path toward using photons in quantum computing, if not in lightsabers.

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.
