I grew up in a household where wasting food was frowned upon, so I always felt guilty if I didn’t go through all the leftovers in my fridge before they got spoiled. Lately, it seems like most people are trying to be eco-conscious about not wasting food. According to the US Environmental Protection Agency, an American family of four loses approximately $1,500 per year on food waste. This figure changes based on the cost of food and the size of a family, with some evidence showing that families w

Decades-Old Waste Barrels Are Creating Toxic Dead Zones off LA’s Coast

gizmodo.com Ellyn Lapointe 2025-10-02 23:15:47

Until 1972, the Pacific waters of Southern California served as a dumping ground for hazardous and industrial wastes. More than 50 years later, corroded metal barrels still litter the seafloor off the coast of Los Angeles, and scientists are only beginning to understand the consequences of casually tossing them into the ocean. Images of the barrels first surfaced in 2020, with some of them encircled by mysterious white halos on the seafloor. Experts initially linked the barrels to DDT—a toxic p

Google pulls the Pixel 10’s Daily Hub to ‘enhance its performance’

If voice translation is halfway between a helpful feature and a gimmick, then Daily Hub leans even further into gimmick territory. It’s a lot like the Now Brief Samsung introduced on its S25 phones, and it’s supposed to act as a quick digest for your day as well as a place to find some inspiration based on your recent activity. It does the first part of that job just fine; it’s maybe a more longwinded version of Google’s At a Glance widget, which gives you a heads up on the weather and upcoming

Hydrogen-Powered Plasma Torch Decimates Plastic Waste in a Blink

gizmodo.com Gayoung Lee 2025-10-11 23:30:56

Why sort plastic when you can blast it to oblivion? Sounds extreme, but that’s the idea behind a new technology with the potential to “realize the era of zero plastic sorting”—while minimizing carbon emissions, too. In a press release today, the Korea Institute of Machinery & Materials (KIMMS) announced the development of a plasma torch that annihilates plastic waste in less than 0.01 seconds—about ten times faster than a blink. The torch is entirely powered by hydrogen and converts mixed plast

In the dead of a cold December night in 2023, at a dump near Delhi, hundreds of men huddled around small bonfires, clutching paper cups of tea. They tossed plastic bags into the flames as they waited for a fleet of trucks to arrive. The trucks rolled in one by one, full of electronic marvels now reduced to e-waste: Nokia, Itel, and Samsung smartphones; Sony and LG LCD screens; Tata air conditioners; Canon and Epson printers.

Why Pooping on Planes Might Actually Be a Good Thing

Researchers have developed a new critical warning system for the spread of antimicrobial resistant (AMR) superbugs: poop and pee from airplane bathrooms. Scientists predict that by 2050, AMR superbugs, or pathogens that don’t respond to antimicrobial medicines, might take more lives than cancer. As such, it’s critical for countries to keep an eye on the global propagation of these dangerous pathogens, which can travel with people, in order to best prepare for future infections.

Most of us are already quite comfortable recycling our household waste.

The United States’ 90,000-ton stockpile of radioactive nuclear waste has long been a liability, but researchers are increasingly eyeing it as a resource. New techniques in transforming spent fuel, new nuclear fuel cycle directives from the Trump administration, and the doling out of a Biden-era $40 million research program together aim to repurpose nuclear waste on a commercial scale.
