European ant is the first known animal to clone members of another species

The same Iberian harvester ant (Messor ibericus) queen produced the hairy male Messor ibericus (on the left) and the hairless male Messor structor (on the right), despite them being members of distantly related species. Queen ants in southern Europe produce male clones of an entirely different species — tearing up the playbook of reproductive biology and suggesting we need to rethink our understanding of species barriers.

Ghost Kitchens Are Dying. Here's the $15 Billion Lesson Every Restaurateur Must Learn. A ghost kitchen stripped away everything you think makes a restaurant a restaurant. No dining room. No servers. No storefront. No customers walking through the door. Just a kitchen. Four walls. Commercial equipment. And a phone that never stops ringing with delivery orders. Ghost kitchens exist only in the digital world. Customers find them on DoorDash, Uber Eats, and Grubhub. They order through an app. Food

Plant Care Tips for the Winter, According to Experts (2025)

wired.com Louryn Strampe 2025-09-26 02:39:00

Indoor plant care is always tricky. While it's all fine and dandy to take care of them when the summer sun is shining, keeping your plants alive in winter can feel like a whole ’nother story. Being a houseplant enthusiast is akin to having several silent children, all with finicky needs and limited ways of communicating them.

Life, work, death and the peasant: Rent and extraction

This is the third piece of the fourth part of our series (I, II, IIIa, IIIb, IVa, IVb) looking at the lives of pre-modern peasant farmers – a majority of all of the humans who have ever lived.

New pathway engineered into plants lets them suck up more CO₂

Lots of people are excited about the idea of using plants to help us draw down some of the excess carbon dioxide we've been pumping into the atmosphere. It would be nice to think that we could reforest our way out of the mess we're creating, but recent studies have indicated there's simply not enough productive land for this to work out. One alternative might be to get plants to take up carbon dioxide more efficiently. Unfortunately, the enzyme that incorporates carbon dioxide into photosynthes

Motion Sickness Sufferers, Rejoice: Scientists Say This Might Actually Help

Judges side with Trump EPA over canceled Inflation Reduction Act grants to nonprofits

Altered states of consciousness induced by breathwork accompanied by music

The popularity of breathwork as a therapeutic tool for psychological distress is rapidly expanding. Breathwork practices that increase ventilatory rate or depth, facilitated by music, can evoke subjective experiential states analogous to altered states of consciousness (ASCs) evoked by psychedelic substances. These states include components such as euphoria, bliss, and perceptual differences. However, the neurobiological mechanisms underlying the profound subjective effects of high ventilation b

You can't grow cool-climate plants in hot climates

Since moving to Deep South Texas 4 years ago I've come to realize that many plants I used to love growing in the cool mild maritime climate of the SF bay area are impossible to grow where I live. This is not just because of the high daytime heat. It's not as simple as that. Specifically, it is the high heat during the night (and those warm nights are a direct result of the humidity) that causes cool-climate and cool-season plants to eventually die here.

If you were to design the strangest diet possible, eating nothing but ants and termites would probably make the shortlist. Yet over the past 66 million years, mammals across the globe have repeatedly gone down this path—not once or twice, but at least a dozen times.
