A team of biologists and robotic engineers have developed a virtual reality system for fish to decipher how they school. They uncovered the natural ‘control law’ that is used by zebrafish to coordinate behaviour with others, a behavioural algorithm that has been tuned over millennia to facilitate effective collective motion. Since such collective behaviour could be highly advantageous for technological solutions, such as in the control of autonomous vehicles, the scientists then tested its performance with groups of robotic cars, drones and watercraft. They found that the rules of interaction that have evolved in fish are highly effective for robotic control, demonstrating their potential for the control of fleets of robots in the future. The research, published in Science Robotics, was led by scientists at the Cluster of Excellence Collective Behaviour, University of Konstanz, and the Max Planck Institute of Animal Behavior (MPI-AB), Germany, in collaboration with researchers at Eötvös University in Hungary and the Massachusetts Institute of Technology (MIT) in the United States.

In 2013, a sea star wasting syndrome decimated populations of Pisaster along the west coast of North America and along the Monterey Peninsula in California, where this study was conducted. The orange and purple stars have a hungry appetite for mussels in the rocky intertidal. Without the voracious sea stars lurking around, mussel populations exploded, expanding in cover from around five percent to more than 18 percent within three years. In the wake of the sea star die-off, mussels became a major prey surplus for sea otters, revealing a surprising link between the adjacent rocky intertidal and kelp forest ecosystems. The new research into the phenomenon shows how the loss of a keystone predator (Pisaster) in one ecosystem can impart changes to another (sea otters), linking ecosystems.

Researchers led by the University of Cincinnati’s Anna Kruyer and the University of Houston’s Demetrio Labate have published research in the journal Science Advances applying object recognition technology to track changes in brain cell structure and provide new insights into how the brain responds to heroin use, withdrawal and relapse.

SAN DIEGO (April 30, 2025) — Many are aware of the dire challenges with plastic waste polluting the ocean, but new research shows it may harm wildlife in ways not previously understood. In a new study just published in the journal Environmental Pollution, researchers from the University of California, Santa Cruz and San Diego Zoo Wildlife Alliance found that plastic swallowed by northern fulmars— seabirds found in the North Atlantic and North Pacific Oceans—can leak chemicals that interfere with the birds’ hormone systems.
