Chicken fat supercapacitors could store green energy of the future

As vital as it is for society to transition to renewable energy, it’s not as easy as simply swapping out fossil fuels for solar panels. To ensure they’re as efficient as possible, power infrastructures need powerful batteries to reliably house their excess generated energy for later use. Storage equipment has increasingly utilized carbon materials due to their natural abundance and efficiency, but making graphene is expensive and pollution-heavy. But carbon can be harvested through other sources—if you have the stomach…

Blasting coffee grounds with ultrasonic waves creates a 60-second cold brew

As the weather continues to warm, many coffee drinkers currently are making their annual transition over to iced coffee. But for those with more sensitive stomachs, cold brew’s comparatively low acidity makes it their preferred year-round caffeine fix. This smoother, creamier, and sweeter brew comes from allowing grounds to steep in refrigerated water for upwards of 24 hours. Unlike hot brewing, the additional time and cooler temperatures draw out less acids while allowing the coffee’s remaining chemicals time to muddle.…

How John Deere’s tech evolved from 19th-century plows to AI and autonomy

Buzzwords like autonomy, artificial intelligence, electrification, and carbon fiber are common in the automotive industry, and it’s no surprise that they are hot topics: Manufacturers are racing to gain an advantage over competitors while balancing cost and demand. What might surprise you, however, is just how much 180-year-old agriculture equipment giant John Deere uses these same technologies. The difference is that they’re using them on 15-ton farm vehicles. A couple of years ago, John Deere’s chief technology officer Jahmy Hindman…

The world’s first 3D-printed salmon is hitting store shelves, and it looks kind of good

The jury may still be out on plant-based meat alternatives’ economic and environmental viability, but experts largely agree that the seafood industry in its current form is untenable. Overfishing presents countless ecological problems, including plastic pollution and the potential for a wholesale collapse of marine biodiversity. Researchers have been experimenting with seafood alternatives for years, but one company is finally ready to bring its offering to market—and it represents a major moment within the industry. Austrian-based food-tech startup Revo Foods…

Solo Stove Pi Prime review: Propane-powered pizza oven supreme

We may earn revenue from the products available on this page and participate in affiliate programs. Learn more › Cooking pizza with a wood fire requires a certain amount of artistry. You have to craft the pie itself, but tending to the fire is a skill all its own. The flame lives and breathes as it burns, which was a key selling point for Solo Stove’s first pizza oven, the Pi. Unfortunately, for culinary dunces like myself, that romantic Neapolitan…

Pick the sweetest, ripest fruit with this science-based guide

If you’ve ever stared at a pyramid of watermelons and just grabbed the one on top, keep reading. You and your probably-subpar melon could use a lesson or two in how to pick the ripest fruit at the market. Produce selection is one of those valuable life lessons most people never get. And honestly, a lot of folks don’t even know what they’re missing. If you didn’t grow up eating summer corn picked that morning, peaches plucked right off the…

3D-printed vegan calamari rings could be next on the menu

The global commercial fishing industry is a major contributor to Earth’s environmental crises and ecological destruction, but you’re unlikely to find many sustainable or vegan seafood alternatives next to the synthetic beef and chicken in grocery stores. That lack of options may soon change, however, thanks to 3D printers, mung beans, and microalgae. At the American Chemical Society’s fall meeting this week, a team from the National University of Singapore presented the results of a newly synthesized mock seafood that…

Inside the US military lab making tube food for spy plane pilots

A buzzer goes off in a large industrial kitchen at an Army base in Natick, Massachusetts. Two small metal tubes full of food—truffle mac and cheese and hash browns with bacon—have been heating up for five minutes in a steam oven and are now ready for eating. Daniel Nattress, a senior food technologist with the military’s Combat Feeding Division, uses a red protective mitt on his right hand to grab them.  Then comes the moment I’ve been waiting for: a…

Kombucha’s health benefits may go beyond our guts

The next time you go grocery shopping, don’t forget to pick up a case of kombucha. Tea lovers have long hailed the funky, fermented drink for keeping the gut healthy and running smoothly, and now we can tack on diabetes management to the list of potential benefits. A small study published on August 1 in the journal Frontiers in Nutrition found kombucha stopped spikes in blood sugar levels for adults with Type 2 diabetes. With the number of Americans with…

Every time a delicious kernel of corn passes your lips or you crunch into a slice of crusty, freshly-baked bread, you can thank a farmer. According to the US Department of Agriculture, farming and food-related industries contributed about $1.3 trillion to America’s gross domestic product in 2021.  It’s not a stretch to say that agriculture is critical to our lives, as is the machinery that prepares the land, plants and fertilizes the seed, precisely pulls the weeds, and harvests it…
