The UK government has announced it will collaborate with Italy and Japan to develop the Tempest, a new fighter jet featuring a plethora of futuristic technologies.
Year 2019 😁 nanoscale fusion.
A research team of fusion scientists has succeeded in developing “the nano-scale sculpture technique” to fabricate an ultra-thin film by sharpening a tungsten sample with a focused ion beam. This enables the nano-scale observation of a cross-section very near the top surface of the tungsten sample using the transmission electron microscope. The sculpture technique developed by this research can be applied not only to tungsten but also to other hard materials.
Hardened materials such as metals, carbons and ceramics are used in automobiles, aircraft and buildings. In a fusion reactor study, “tungsten,” which is one of the hardest metal materials, is the most likely candidate for the armour material of the device that receives the plasma heat/particle load. This device is called divertor. In any hardened materials, nanometer scale damages or defects can be formed very near the top surface of the materials. For predicting a material lifetime, it is necessary to know the types of the damages and their depth profiles in the material. To do this, we must observe a cross-section of the region very near the top surface of the material with nano-scale level.
For the observation of the internal structure of materials with nano-scale level, transmission electron microscope (TEM), in which accelerated electrons are transmitted through the target materials, is commonly used as a powerful tool. In order to observe a cross-section very near the top surface of the tungsten with TEM, we firstly extract a small piece of the tungsten sample from its surface and then fabricate an ultra-thin film by cutting the extracted sample. The thickness of the film must be below ~100 nm (nanometer) to obtain high resolution due to the high-transmission of the electron beam (IMAGE 1). However, it has been extremely difficult to fabricate such an ultra-thin film for the hard materials such as a tungsten. Therefore, it has been almost impossible to obtain the ~100 nm thickness level by using conventional thin-film fabrication technique.

3D printers work by laboriously printing objects layer by layer. For larger objects, that process can take hours or even days.
But now scientists at the University of California, Berkeley have found a shortcut: a printer that can fabricate objects in one shot using light — and which could, potentially, revolutionize rapid manufacturing technology.

Remember back in the mid-80s, when mass-produced holograms were such a big deal? Since then, they’ve become common on credit cards, currency and other items. Now, thanks to new research, you can actually eat the things.
First of all, why would anyone want an edible hologram? Well, along with simply being used for decorative purposes, they could conceivably also serve to show that a food item hasn’t been tampered with, or to display its name and/or ingredients in a way that proves it isn’t a counterfeit product.
Scientists have already successfully molded edible holograms into chocolate, although only certain types of chocolate worked, and a new mold had to be created for each hologram design. Seeking a more versatile alternative, researchers at the United Arab Emirates’ Khalifa University of Science started out by mixing corn syrup and vanilla with water, then letting the solution dry into a film.

By exploiting polarization entanglement between photons, quantum holography can circumvent the need for first-order coherence that is vital to classical holography.

Summary: A new optogenetics-based technique allows researchers to control neuron excitability.
Source: MIT
Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they communicate with other neurons to form circuits.
Research has shown that people with shorter genes age faster, die sooner and are more prone to disease, and this applies to all animals — scientists found that longer and shorter genes linked to longer and shorter lifespans, respectively Scientists have discovered a “single concise” phenomenon that will be able to determine how long you will live, according to new research.
