The best use for 3D bioprinting? Reconstructing Van Gogh’s severed ear, obviously

Add as a preferred source on Google

The stuff that people are 3D printing these days just keeps getting crazier. One day it’s researchers printing a working speaker, and the next day you hear about somebody who’s figured out a way to print fruit. It’s absolutely nuts, but just when you think 3D printing has reached peak weirdness, something like this pops up:

A Dutch artist by the name of Diemut Strebe has apparently joined forces with a team of scientists to print a true-to-life reconstruction of Vincent Van Gogh’s severed ear. And it’s not just some half-baked plastic rendering either. Thanks to a sophisticated 3D bioprinter and some meticulous DNA research, the ear is printed with living human cells taken from Liewe Van Gogh, the great-grandson of Vincent’s brother Theo, who happens to share about 1/16th of the same genes as the famed 19th century painter.

So, technically speaking, this representation isn’t the exact same ear that Van Gogh chopped off himself and delivered to a brothel back in 1888 — but it’s pretty damn close. Originally, the plan was to use Van Gogh’s actual DNA, extracted from an envelope that he supposedly licked back in the 19th century. But after testing the envelope, the DNA turned out to be somebody else’s, so Strebe was forced to climb down the family tree and find the painter’s nearest living relative.

The crazy thing is, because it’s grown from living human cells, the ear is technically alive. And as if that wasn’t weird enough, thanks to the help of embedded microphones that are linked up to a computer, it can actually hear, too. Visitors to the The Center for Art and Media in Karlsruhe, Germany —where the ear is currently on display— can speak into the reformed appendage and have their words understood.

“You can talk to the ear. The input sound is processed by a computer using software that converts it to simulate nerve impulses in real time. The speaker remains in soliloquy. The crackling sound that is produced is used to outline absence instead of presence.” explains the museum.

The piece is on display in Germany until July 6th, and will be coming to New York in spring 2015.

Anker just exposed a big problem with portable power stations
Appliance, Device, Electrical Device

When you're shopping for a portable power station, there's one number that's almost impossible to ignore: battery capacity. A 2 kWh battery should give you roughly 2 kWh of usable power, right? Unfortunately, things aren't quite that simple. Anker SOLIX has published new efficiency data for its S Series portable power stations, and it's putting the spotlight on something that doesn't get nearly as much attention as capacity: how much of the energy stored inside the battery actually makes it to your devices.

According to Anker, portable power stations are commonly advertised with efficiency figures measured under relatively heavy loads, where they can reach roughly 89% to 92% efficiency. But that's not necessarily how most people use one during an outage. Think about what you'd actually plug in. A Wi-Fi router might sip power continuously, a refrigerator switches its compressor on and off throughout the day, and a CPAP machine could run overnight. Together, those devices may draw just a fraction of what a large power station is capable of supplying. And that's where efficiency can start slipping.

OpenAI’s first gadget sounds like a tiny expressive AI companion
The device will have a doughnut-shaped body, built-in cameras, and moving parts

For months, reports have suggested that OpenAI’s first hardware product would be a screen-free smart speaker designed to act more like an AI companion. We already knew it could understand its surroundings, be carried around the home, and proactively help users. A new Bloomberg report now gives us a clearer picture of what the device may actually look like.

As per the report, OpenAI’s first gadget will be shaped like a doughnut and measure about the same size as a hockey puck. You will be able to carry it between rooms or leave it nearby on whatever surface is convenient. The device is expected to be on the expensive side, as the company has pondered pricing it around $300 to $400. A release is currently planned for 2027.

Google Antigravity just built an AI translator that works without the internet
Electrical Device, Switch, Robot

Google has shown off a new AI project that could make language barriers a little less intimidating, and it doesn't need an internet connection to do it. The company has introduced the Gemma Translator, a compact prototype built in collaboration with Antigravity. Unlike most AI translation tools that rely on cloud processing, this device runs entirely offline using Gemma 4 E2B, Google's lightweight open model. Everything happens locally on the device, making it both portable and independent of an internet connection. The prototype is powered by a Raspberry Pi 5 and includes a microphone and speaker inside a custom 3D-printed enclosure, creating a self-contained translator you can carry almost anywhere.
