Advancements in synthetic skin could lead to better prosthetics

New Electronic Skin Communicates With the Brain Just Like Your Actual Skin (from FB):
A team of engineers at Stanford University has created a revolutionary soft electronic skin that communicates directly with the brain, mimicking the function of natural nerve signals.
Unlike previous iterations that rely on external devices, this next-gen e-skin senses temperature and pressure, converting them into electrical impulses similar to those sent by human nerve endings.
This innovation follows other cutting-edge projects, like a spray-on skin for gesture recognition and a smart bandage that monitors wound healing. Engineers at MIT and Graz University of Technology are also pushing the boundaries with sweat-proof e-skins and hybrid materials that detect temperature, moisture, and pressure.
The Stanford e-skin is made up of layers just nanometers thick, using materials like the rubber found in surgical gloves. The final product, supported by a substrate to maintain durability, is as thin as a sheet of paper. Operating at just 5 volts, the e-skin offers safe, sensitive feedback—potentially transforming prosthetics by providing a realistic sense of touch. Future goals include wirelessly transmitting these sensory signals to chips embedded in the nervous system, allowing prosthetic users to move their limbs naturally. With ongoing research focused on enhancing these capabilities, the Stanford team is inching closer to making human-prosthetic integration a reality.

US Special Forces Rifles

It appears that rifles developed in the 1980s, firing cartridges developed nearly a century ago are still what our Special Forces need.

One reason for keeping the large 50 caliber round is that it has enough room to fit explosives or incendiaries when they would be most effective.

There is (always) some talk of moving to a smaller round.  A bullet doesn't need to be a specific diameter to hit a target with sufficient energy to destroy it.  Also, cartridge cases can get smaller as propellants get more powerful and gun metals get stronger.  Small lighter cartridges make it easier to carry more rounds, but they need to be as effective (or more so) than the ones they're replacing.  This article is about different military rounds, but it makes the point:

I find it interesting that the current Barrett 50 caliber used by our troops is semi-automatic.  In civilian distance competitions, Barrett's bolt-action rifles in the same caliber are more accurate.  Perhaps the rate of fire (and the demands of urban combat) is nearly as important as it's accuracy in current combat scenarios.

DVD Drives Turned Into Microscopes

https://hackaday.com/2022/10/01/dvd-drives-turned-into-microscopes/

https://kototoibashi.github.io/dvd-pickup-microscope-poc/

" This build requires two DVD pickups. By scanning once horizontally and once vertically and measuring the returning light from the DVD laser, an image can be created. For this build, the second pickup is used to move the object itself. The entire device is controlled by an Analog Discovery 2, although this principle could be ported to other microcontroller platforms. Thanks to the extremely fine laser in a DVD and the precise movements of the motors found in the control machinery, the images obtained using this method have the potential to be more detailed than comparable visible light microscopes.

While this isn't quite scanning electron microscope territory, it's good enough to clearly image the internal workings of a de-capped integrated circuit."
