3D printing could be key to creating authentic-tasting cow's milk, without the cows

3D printing has a whole host of use cases, but one that you might not previously have thought of is the use of additive manufacturing to create cow’s milk — minus the cows.

That’s the mission statement of a startup called Perfect Day Foods, founded by two twenty-something biomedical scientists. The firm has so far raised $4 million from investors. Perfect Day’s plan? To create a lactose-free milk substitute that’s a whole lot closer to the real thing than existing milk substitutes.

“Just before we started this company, my co-founder Perumal Gandhi and I had recently adopted a plant-based diet and were finding it hard to live without some of our favorite foods: namely, ooey, gooey, cheesy pizza,” co-founder and CEO Ryan Pandya told Digital Trends.

He continued that the pair knew of people who were using food technology to create meat without animals, and wondered why nobody was doing the same for milk.

“Our goal isn’t to be an alternative, it’s to be delicious,” he continued. “So whether it’s a Perfect Day yogurt, cheese, butter, or ice cream, it will taste as good as the real thing and be better for you. We want to empower people to enjoy the foods they love, while making the world a greener, kinder place. We don’t think you should have to sacrifice one of the other.”

As Pandya explained, Perfect Day uses yeast fermentation to make its milk, utilizing 3D-printed cow’s DNA as part of the process.

“It’s a process akin to craft brewing and … allows us to create real milk proteins that are identical to the ones found in cow’s milk, without a single cow,” he said. “First, we start with a yeast that’s safe and well understood, which we sourced from the USDA. We give this standard yeast a ‘blueprint’ from 3-D printed cow DNA that allows it to ferment sugar and create real milk proteins. We then carefully separate these milk proteins and combine them with plant-based sugar, plant-based fats, and nutrients to produce a product that has the identical taste and texture of cow’s milk, but packs in more nutrition with no food safety or contamination concerns.”

The cream on this already impressive high-tech milkshake? It boasts a significantly longer shelf life than regular cow’s milk.

As to when customers will be able to get their hands on Perfect Day’s vegan, lactose-free, more sustainable milk substitute, Pandya told Digital Trends it won’t be too long. “We’re focused on product formulation and commercialization as we look to bring our products to market by the end of next year,” he said.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying
Split image of Breaking Bad anime characters.

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
