University of Lausanne biologists chipped hundreds of ants and digitally tracked them to see how they form social groups and work collectively to get stuff done. Based on the data, they created heat maps and visualized the ants' trajectories. From Nature:
The biologists… have found that the workers fall into three social groups that perform different roles: nursing the queen and young; cleaning the colony; and foraging for food. The different groups move around different parts of the nest, and the insects tend to graduate from one group to another as they age, the researchers write in a paper published today in Science.
“The paper is a game-changer, in the size and detail of the data set that was collected,” says Anna Dornhaus, an entomologist at the University of Arizona in Tucson.

Below is a video, accelerated five times.
The large black bear in this video was observed ambling around a Monrovia, California neighborhood last Friday morning. The bear walked through residential lawns, driveways and rested in a nearby alley.
How does an owl’s tail help it fly? To better see the role of the tail in raptor aerodynamics, researchers at the UK’s Royal Veterinary College recorded birds of prey flying through clouds of tiny helium bubbles. According to the science journal Nature, analyzing the swirling motion of the bubbles enabled the scientists to discover […]
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
Whether you’re managing a political campaign or building a client base, there comes a time when you stop seeing people and start seeing numbers. This doesn’t happen suddenly. You shake hands, make calls, and build relationships. And then those relationships disappear into a database of donors or customers as your organization grows. People get brought […]
Learning to ride a bike is one of those quintessential childhood experiences that’s as rewarding as it is scary. Prep your precious babe for success by starting them early with the world’s lightest balance bike, the Brilrider FLIGHT. For the uninitiated, balance bikes are no-pedal bicycles that propel forward by pushing off the ground with […]
With so many advancements in modern society, you’d think we’d have moved beyond the butane lighter by now. A pressurized, flammable gas, butane fumes can irritate your eyes and skin, can elevate your heart rate, and even lead to cardiac arrest. And we did mention that whole highly pressurized and flammable part, right? While certainly […]
