An Augmented Reality Sight? The Self-Zeroing Foresight Smart Optic from Meprolight [SHOT Show 2020]

Meprolight describes their new Foresight optic as an Innovative Augmented Sight. Externally, it doesn’t look much different from Meprolight’s other red dot sights like the M5 Pro, but internally the hard and software is very different. The Mepro Foresight boasts the a number of features that stand out in the red dot market. It offers an almost computer game-like heads up display.

Not only does the Foresight have a reticle but it also has a compass feature, a leveller and in the near future will also enable round counts to be tracked. The sight is software, rather than hardware, driven with bluetooth connectivity and its own dedicated app – Meprolight, which allows customisation of settings and finer control of the sight’s features. The optic itself weighs 9.9 ounces and is 4.6″ x 2.35″ x 2.68″ in its dimensions.

Rather than running on a conventional cell battery it uses a rechargeable battery that can be charged with a USB-C cable. The sight without the app comes with 5 in-built reticles but with the app this grows to 10 with customisable settings.The app is currently available on bother apple and android phones. These reticles and various settings can be set to particular rifles to enable zeros with different weapons to be stored on a smartphone. Meptolight also confirm that the sight works well with magnifiers and further updates will arrive in the future.

The next update is imminent and the most interesting new feature will be the inclusion of a shot counter which will help users track how many rounds you have put through the host gun. The round counter is based on vibration and recoil impulses to provide an accurate round count which might be used for maintenance scheduling. The counter is user defined and will track the round count from use to use of the weapon, even after the sight has been turned off and on with each use. Future features might include an onboard camera or a laser rangefinder built in.

Eventually, you just attach your smartphone on top of your gun; it has cameras, and do any number of calculations that will tell you what's out there, if your barrel is pointing in the correct direction, and predict where the target will move next.

A New Laser Technology Can See Inside Our Bodies Like Never Before

While X-rays can produce harmful radiation, a new technique using laser-induced sound waves provides highly detailed images of the structures in our bodies.

Photoacoustic imaging is an emerging imaging technique that shoots micro-pulses of laser light at a specimen or body part, which selectively heats up parts of the tissue causing them to expand, and generate waves of pressure –– a.k.a. sound waves.

Ultrasonic sensors are situated to capture these microscopic changes, and a processing software then reconstructs the image based on what the sensors “hear.” The speed of the laser can be adjusted depending on what type of tissue one would like to visualize.

The photoacoustic imaging technique is beginning to take off in both the medical and scientific worlds, as it provides us with super clear, incredibly detailed images of the human body and the structures inside it.

Not to mention, the imaging technique causes no discomfort and there is no dangerous ionizing radiation involved, making it a desirable alternative to more traditional imaging, like a CT scan, ultrasound, or a PET scan.

Not only can this new imaging technology be used to image tissues at extremely high resolution, you can also introduce a foreign material, like a contrast dye or a specially designed nanoparticle, to see things you might not be able to otherwise.

Although the technique has been around for more than a century, photoacoustic imaging is just starting to be clinically explored as an alternative and prototype clinical machinery is in development.

Learn more about this revolutionary imaging technique on this episode of Elements.

X-rays, emitted by a tube mounted near the floor, penetrated the shoes and feet, then struck a fluorescent screen on the other side."

This 3D-Printed Bunny Could Be the Future of Data Storage

Just like 1s and 0s are the way computers encode information, DNA base pairs do the same. And although this plastic rabbit is not alive, instructions for how to replicate it are encoded into the rabbit itself.

But DNA offers more density than 1s and 0s, packing all of the instructions for a human body into the nucleus of a cell. And research teams around the world have been demonstrating that they’re able to encode hundreds of thousands of terabytes of digital data in GRAM-quantities of DNA.

Picture hundreds of thousands one-terabyte hard drives and all of the information you could store on them—videos, photos, and more—and then picture all that information being stored in just a few grams of biological material. DNA offers quite the improvement to existing digital data storage methods, like the chips, spinning discs and magnetic tape that you might be used to.

And this 3D-printed plastic rabbit is a first foray into what researchers are calling the ‘DNA of Things.’ So how exactly do you get DNA into a plastic object like this?

Find out more about this innovation, what it could mean for the future of data storage, as well as how it could be utilized in all kinds of industries, like construction, pharmaceuticals and electronics in this Elements.

'Magic' Angle Graphene Is BACK...with an Even Bigger Twist

In 2018, the discovery of something called a “magic angle” in graphene rocked the physics community.

Graphene is a single-atom thick layer of carbon that forms a hexagonal lattice pattern, and its atomic arrangement gives graphene certain exciting properties, like being more than 200 times stronger than steel, flexible, transparent, and highly conductive.

And that last property, the highly conductive one, was highlighted in 2018 when researchers put two layers of graphene on top of each other and twisted them at exactly 1.1 degrees. They cooled the graphene structure to just above absolute zero, applied a strong electric field, and found that not only are these graphene bilayers highly conductive...but that they exhibit alternating areas of conductivity and insulation.

This means that scientists saw graphene bilayers (with a twist) behaving like a superconductor. And the thing is, we don’t really know why.

And now this year, while exploring the capabilities of this seemingly ‘magical’ twist further, scientists uncovered something that is arguably an even bigger deal.

An international team at the Institute of Photonic Science in Barcelona made what they call ‘magic-angle twisted bilayer graphene devices,’ by taking two stacks of graphene rotated at the magic angle, and using a mechanical squeezing process to eliminate impurities. This version of the experiment allowed researchers to see details they hadn’t before, like the device’s incredible versatility.

Find out more about how this magic angle graphene can act as an insulator, superconductor, or magnet on this Elements.

Lithium Glass batteries move to next stage
by NICK FARRELL on25 FEBRUARY 2020

Battery technology might have legs

For ages, we have been writing about battery breakthroughs and yet none of them seems to appear in your smartphone. However, a rapid-charging and non-flammable battery developed in part by 2019 Nobel Prize winner John Goodenough (pictured) has been licensed for development by the Canadian electric utility Hydro-Québec.

The cunning plan is to have the batteries ready for one or more commercial partners in two years.

Hydro-Québec, according to Karim Zaghib, general director of the utility’s Center of Excellence in Transportation Electrification and Energy Storage, has been commercializing patents with Goodenough’s parent institution, the University of Texas at Austin, for the past 25 years.

Goodenough and Maria Helena Braga, professor of engineering at the University of Porto in Portugal, developed a solid-state lithium rechargeable that used a glass doped with alkali metals as the battery’s electrolyte. The electrolyte is the material between cathode and anode and is often a liquid in today’s batteries, which typically means it’s also flammable and potentially vulnerable to battery fires.

Braga said her and Goodenough’s battery is high-capacity and charges in “minutes rather than hours”, performs well in both hot and cold weather, and that its solid-state electrolyte is not flammable.

“For the next two years we do research and development in order to prove the concept and to scale the materials”, Zaghib said.

Hydro-Québec’s research lab, which Zaghib says comprises 120 people, works with both early-stage technologies like the Goodenough glass battery and also with technologies already at commercial scale.

This latter category includes another Goodenough invention, the lithium iron phosphate battery.

“This is one of the safest materials for lithium-ion today”, Zaghib said. “It’s used for electric buses and for energy storage.”

Beginning in 1996, Zaghib says, Goodenough and Hydro-Québec struck up a partnership to commercialize this lithium battery. Licensees of this technology include the now Chinese-owned A123 and the Japanese battery company Murata Manufacturing.
