A.I. "predator" drones can now spot and track illegal poachers
Poachers trade on a black market estimated to total $40 billion. It’s impossible to stop every poacher, but new technology could bolster the efforts of conservationists by putting a set of eyes in the sky.
Poaching takes a brutal toll on the world’s wildlife every year. By the thousands, rhinos are for killed for their horns, elephants for their ivory, and tigers for their bones and exotic pelts. To protect these animals, rangers and conservationists must monitor enormous swaths of land, day and night, looking for poachers who trade on a black market estimated to total $40 billion. It’s impossible to stop every poacher.
New technology could bolster the efforts of conservationists, though, by putting a set of eyes in the sky. Air Shepherd, a conservation group, recently field tested an AI drone system that’s able to automatically detect humans and animals through infrared thermal imaging. The SPOT (Systematic POacher deTector) system, developed by researchers from Carnegie Mellon, the University of Southern California, and Microsoft, can be operated on a common laptop with a wireless internet connection, allowing park rangers to get advanced knowledge of poachers’ movements so they can be intercepted. It could also provide park rangers a heads-up in situations where they’re heading toward a large group of armed poachers.
The researchers trained the system through deep learning, a branch of A.I. that seeks to enable computers to learn and recognize patterns in the world — images of animals and poachers, in this case. First, the SPOT system was shown a series of images in which humans had marked where the animals and humans were. Then, the system used that information to learn about what to look for on its mission.
A paper published by the researchers in November, 2017 describes the deep-learning process in greater detail.

We take fewer mental pictures per second.
- Recent memories run in our brains like sped-up old movies.
- In childhood, we capture images in our memory much more quickly.
- The complexities of grownup neural pathways are no match for the direct routes of young brains.
In the face of seemingly unstoppable gun violence, Americans could stand to gain by looking to the Swiss.
- According to a recent study, the U.S. had the second highest number of gun-related deaths in 2016 after Brazil.
- Like the U.S., Switzerland has a high rate of gun ownership. However, it has a considerably lower rate of deaths from gun violence.
- Though pro-gun advocates point to Switzerland as an example of how gun ownership doesn't have to correlate with mass shootings, Switzerland has very different regulations, practices, and policies related to guns than America.
It's one of the most consistent patterns in the unviverse. What causes it?
- Spinning discs are everywhere – just look at our solar system, the rings of Saturn, and all the spiral galaxies in the universe.
- Spinning discs are the result of two things: The force of gravity and a phenomenon in physics called the conservation of angular momentum.
- Gravity brings matter together; the closer the matter gets, the more it accelerates – much like an ice skater who spins faster and faster the closer their arms get to their body. Then, this spinning cloud collapses due to up and down and diagonal collisions that cancel each other out until the only motion they have in common is the spin – and voila: A flat disc.
