Scientists have taught a goldfish to drive a robotic car in an experiment to assess its innate navigational abilities and further explore animal behaviour. The robotic driving setup built by scientists from Ben-Gurion University in Israel consists of a set of wheels under a goldfish tank with a camera system to record and translate the fish's movements into forward, back and side-to-side directions to the wheels. In the study, published last month in the journal Behavioural Brain Research, they tested whether the fish could navigate by placing a clearly visible target on the wall opposite the tank. Since navigation plays an important role in the animal kingdom, the scientists wanted to explore if there are universal properties independent of species, ecology and brain structures. They sought to understand if a species embedded in the environment of another one could cope with an otherwise familiar navigation task.
These results demonstrate how a fish was able to transfer its space representation and navigation skills to a wholly different terrestrial environment. This suggests that the way even creatures on the order of goldfish get around is not some kind of hard-coded aquatic movement circuit but something more universal, perhaps one that evolved earlier and at a more basic level than we think. Just how abstract or universal is yet to be determined, but it's an interesting result to be sure. More importantly, however, it means there's a pretty good chance that you'll be able to get a mobile terrarium for your fish, iguana, skink, perhaps even your tarantula, allowing it the freedom of the house without actually letting it slither or scuttle everywhere.
The Matterhorn, an Alpine peak that straddles the border between Switzerland and Italy, is one of the most iconic mountains in the world. Isolated at the head of the Zermatt Valley, climbing the perfectly shaped mountain, which has a summit height of 4470 m above sea level, is on the to-do list of thousands of climbers – and some physicists. In 2019, an international team of scientists set out to take a closer look at the Matterhorn and installed several seismometers at different locations to record its movement. They found that despite the Matterhorn appearing like a huge immovable mass, it is in fact constantly on the move, swaying gently back and forth about once every two seconds. The researchers say that this subtle vibration, with a fundamental frequency of 0.42 Hz, is stimulated by seismic energy in the Earth originating from oceans and earthquakes, as well as – rather surprisingly – human activity.
His case rests on a viral video he tweeted last month of a goldfish driving a water-tank-equipped robotic vehicle down the side of a street and inside his lab at Ben-Gurion University of the Negev in Israel. The roboride was part of a scientific study to test whether goldfish had the mental acuity to navigate a terrestrial environment toward a target using a machine. The six goldfish that took part in driver's training passed their test. They weren't the first to cross the finish line. Other neuroscientists have taught rats to drive cars as part of experiments testing how experience affects learning.
The 2021 Cadillac Escalade is available with the latest version of GM's hands-free Super Cruise highway driving aid. Fox News Autos Editor Gary Gastelu lets it take him for a ride. Now this is a driving school. Researchers at Ben Gurion University have built a tank that a fish can drive around on land. Researchers at Israel's Ben-Gurion University have built a self-propelled fish tank on wheels that goldfish inside can drive around on land with intent.
