At the University of Minnesota, researchers have 3D printed a functioning centimeter-scale human heart pump. Bioprinting techniques have developed tremendously in recent years, and research teams around the world are studying how such techniques could be used to cure heart conditions.
More precisely, the researchers had tried in the past to 3D print heart muscle cells that were derived from pluripotent human stem cells, in other words cells with the potential to develop into any type of cell in the body.

Odroid C4 vs RaspberryPi 4
Odroid C4 & Raspberry Pi 4 head-to-head, including specifications, CPU benchmarks, GIMP filter test, drive (hdparm) tests, and YouTube playback. Tests conducted in Ubuntu 20.04 (64 bit on both boards), as well as Ubuntu MATE and Raspberry Pi OS.
Repair Shop in Poland Still Uses Commodore 64 For Business
Poland – Tell us, are you tired of the current consumer society where you change your smartphones and personal computers like socks? Well if you are, then you are not alone. One auto-mechanic shop in Gdansk (Poland) also shares your pain and they didn’t change their PC for 25 years.
They stopped to produce these computers back in 1994, but this auto-mechanic shop in Poland still uses it. Jokingly they said “Good things should not be changed”.
Android TV 10 For The Raspberry Pi 4 With Hardware Acceleration
In this video, we take a look at an all-new release of Android TV based on Android 10 for the Raspberry Pi 4! This build is a little special because it actually has hardware acceleration so games and apps that rely on Open GL will work with this build!

Scientists 3D Print Gunpowder Substitute, Achieve 420M/S Bullet Velocity
Researchers from the Xi’an Modern Chemistry Research Institute in China have 3D printed a functional gun propellant using SLA technology. The gunpowder-esque substance is a carefully constructed blend of photopolymer resin, RDX (a high explosive), and other reactive additives. Initial gun testing of the 3D printed propellant has garnered some promising results, as the scientists managed to achieve a more-than-lethal muzzle velocity of 420m/s. This, of course, depends on your definition of ‘promising’.
Nvidia RTX 3080 Ti could require upgraders to rip out most of their PC
New rumors are doing the rounds that suggest the Nvidia RTX 3080 Ti, and other upcoming Ampere graphics cards, could require a new 12-pin PCIe connector to provide the requisite power – and if true this could prove very frustrating for potential upgraders.
While current Nvidia graphics cards usually use eight-pin connectors from the PSU (power supply unit) to run, but a new technical illustration suggests that Nvidia is looking at using a new 12-pin PCIe power connector, measuring around 19 x 14 x 8.35mm.
Emulate ZX Spectrum on emulated Commodore 64 on emulated DOS on emulated Windows on Linux
An emulator is a program that allows one system (eg. Windows) to run programs built for another system (eg. ZX Spectrum). It is mainly used to play old 8-bit games on today’s PCs. In other words, a complete waste of time.
What we will do is emulate Windows on a Linux system. Then we will run a DOS emulator under Windows. Then we will run a Commodore 64 emulator in this emulated DOS environment. Finally, we will run a ZX Spectrum emulator on the emulated Commodore machine.
