As even casual Star Wars fans will know, lightsabers are probably the coolest weapon ever to make an appearance on the big screen. Lightsaber fights are so elegant that they are almost hypnotic and, even though not all of us might have a strong enough flow of Force running through our veins, a lightsaber in the right hand is by far the deadliest weapon to be found in the universe.

The idea behind a lightsaber is simple genius: a light-weight and immensely powerful tool that uses a blade of energy to not only slice up disciples of the Dark Side in a single blow but also act as an effective shield against laser blasts. So why don’t we have working lightsabers in real life? Surely physicists must be smart enough (and big enough Star Wars fans) to be able to produce one of these incredible objects.

It’s basically a lightsaber. Except smaller. And with an invisible blade. And cold to the touch. But other than that, this homebrew cold plasma torch (YouTube, embedded below) is just like the Jedi’s choice in elegant weaponry.

Perhaps we shouldn’t kid [Justin] given how hard he worked on this project – seventeen prototypes before hitting on the version seen in the video below – but he himself notes the underwhelming appearance of the torch without the benefit of long-exposure photography. That doesn’t detract from how cool this build is, pun intended. As [Justin] explains, cold plasma or non-equilibrium plasma is an ionized stream of gas where the electron temperature is much hotter than the temperature of the heavier, more thermally conductive species in the stream. It’s pretty common stuff, seen commercially in everything from mercury vapor lamps to microbial sterilization.

In the world of Halo, Master Chief is a super soldier outfitted with one of the most advanced sets of body armor ever produced by mankind. So how bullet proof if Master Chief? Master Chief Doesn’t Want to Die.

The force is strong not only in Star Wars lore but also as a fundamental property in physics. For example, scientists can put two uncharged metal plates close together in a vacuum, and “voila!” —-they will attract each other like Luke Skywalker and his trusted lightsaber.

In 1948, Dutch theoretical physicist Hendrick Casimir first predicted an attractive force responsible for this effect—later dubbed the Casimir effect. A half-century later, in 1996, the Casimir force was experimentally measured for the first time by Steve Lamoreaux at Los Alamos National Laboratory.

But just like the light and dark side of the force in Star Wars, scientists have wondered, can there be an equal yet opposite kind of Casimir force?

Inspired by the Star Wars movie franchise, this newly recognized sport by the French is different from how the other weapons are used in fencing. For one, it requires combatants to pull their sword from behind themselves before they can try to strike their opponent. It also has rounds that last three minutes. And the first duelist who will reach 15 victories will be announced as the winner.

BEAUMONT-SUR-OISE, France (AP) — Master Yoda, dust off his French, he must.

It’s now easier than ever in France to act out “Star Wars” fantasies, because its fencing federation has borrowed from a galaxy far, far away and officially recognized lightsaber dueling as a competitive sport, granting the iconic weapon from George Lucas’ saga the same status as the foil, epee and sabre, the traditional blades used at the Olympics.

Of course, the LED-lit, rigid polycarbonate lightsaber replicas can’t slice a Sith lord in half. But they look and, with the more expensive sabers equipped with a chip in their hilt that emits a throaty electric rumble, even sound remarkably like the silver screen blades that Yoda and other characters wield in the blockbuster movies.

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.
