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.

That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
As AI improves, the mystery of consciousness interests more programmers and physicists.
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]
They probably just sleep a lot. But still, you can remotely keep an eye on them when you’re at work and missing them deeply with this HD monitor from Kodak.If you have a new puppy that destroys everything in sight, or you just want to be a little more security-conscious, this WiFi camera is a […]
Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
