While intense magnetic fields are naturally generated by neutron stars, researchers have been striving to achieve similar results for many years. UC San Diego mechanical and aerospace engineering graduate student Tao Wang recently demonstrated how an extremely strong magnetic field, similar to that on the surface of a neutron star, can be not only generated but also detected using an X-ray laser inside a solid material.

Wang carried out his research with the help of simulations conducted on the Comet supercomputer at the San Diego Supercomputer Center (SDSC) as well as Stampede and Stampede2 at the Texas Advanced Computing Center (TACC). All resources are part of a National Science Foundation program called the Extreme Science and Engineering Discovery Environment (XSEDE).

“Wang’s findings were critical to our recently published study’s overall goal of developing a fundamental understanding of how multiple laser beams of extreme intensity interact with matter,” said Alex Arefiev, a professor of mechanical and aerospace engineering at the UC San Diego Jacobs School of Engineering.

Occasionally we come across a piece of information which reminds us that, while flying cars are still nowhere to be found, we’re definitely living in the future. Usually it’s about some new application of artificial intelligence, or maybe another success in the rapidly developing field of private spaceflight. But sometimes it’s when you look at a website and say to yourself: “Oh cool, they have 1.5kW electromagnetic accelerators in stock.”


Arcflash Labs, a partnership between [David Wirth] and [Jason Murray], have put their EMG-01A Gauss gun up for sale for anyone who’s brave enough and willing to put down $1,000 USD on what’s essentially a high-tech BB gun. The creators claim it obtains an efficiency of 6.5% out of its RC-style 6S LiPo battery pack, which allows it to fire over 100 rounds before needing to be recharged. Firing 4.6g steel projectiles at a rather leisurely 45 m/s, this futuristic weapon would be more of a match for tin cans than invading alien forces, but at least you’ll be blasting those cans from a position of supreme technical superiority.

The EMG-01A builds on the work of the team’s previous experiments, such as the semi-automatic railgun we covered last year. They’ve made the device much smaller and lighter than their previous guns, as well as worked on making them safer and more reliable. That said, the page for the EMG-01A has a number of warnings and caveats that you won’t see on the back of a Red Ryder BB gun box; it’s certainly not a toy, and anyone who takes ownership of one needs to be respectful of the responsibility they’re taking on.

Of all the crazy garage-built weapons I’ve ever come across, this one from YouTuber/tinkerer Alex Smyth is definitely one of the craziest. Aside from the fact that it looks like a prop that was stolen from the set of District 9, Smyth’s “phased plasma” gun doesn’t just fire normal projectiles. It’s actually designed to fire rounds filled with ionized plasma, which in turn should, at least in theory, explode on impact.

If you’re unfamiliar, a railgun is a type of weapon that uses electricity instead of gunpowder to fire a projectile. Leveraging a phenomenon called the Lorentz Force, rail guns work by delivering a high power electric pulse to a pair of conductive rails, which in turn generates a magnetic field and rapidly accelerates the bullet situated between them.

Smyth’s gun is a bit different, though. Rather than using straight rails, his build features a pair of rails that are twisted to form a double helix. According to Smyth, this gives the projectile some spin and extra stability, just like the rifling on a firearm barrel would provide for a normal bullet. The only difference is that, in lieu of a regular metal projectile, Smyth’s gun is designed to fire glass vacuum tubes filled with neon gas. In theory, the electromagnetic fields created by the rails will ionize the gas to create plasma, which will be released when the glass projectile breaks.

The Ministry of Defence has appointed an Oxford University professor as its first female Chief Scientific Adviser.

Dame Angela McLean, 58, will oversee the department’s core research programme and technology strategy in the role.

She has been a senior research fellow at Oxford University since 1990 and currently works on Theoretical Life Science at All Souls College.

What’s in a name? A little thought and a good cause, according to Jeff Bezos who was recently pressed about why he named his space company “Blue Origin.”

The Amazon founder recently spoke at the JFK Library for a fireside chat event. During the 50 minute conversation, he was asked about his other company, Blue Origin.

Northwest is primed for the space economy.
