Cornell engineers have developed a robotic collective that behaves less like a machine and more like a material that flows, reshapes, and adapts to its environment without centralized control. The system, called the Cross-Link Collective, consists of dozens of small robots that have limited mobility individually, but together exhibit coordinated and sustained motion. The research, published May 20 in Science Robotics, demonstrates a robotic system that resembles soft matter, continuously deforming and reorganizing as it moves, driven by what researchers call mechanical intelligence.

E pluribus unum – “out of many, one” – is not only a motto for the United States. It’s a good credo for microrobots. A research collaboration between Cornell and the Max Planck Institute for Intelligent Systems has shown how a swarm of microrobots spinning on a water surface can together generate the fluidic torque needed to manipulate passive structures without any physical contact. This collective behavior was demonstrated to operate gears and move objects, with the aim of eventually performing microscale tasks and biomedical procedures. “At small scales, contact-based manipulation can be limiting, and flow-based manipulation offers a great alternative,” said Kirstin Petersen, associate professor and an Aref and Manon Lahham Faculty Fellow in the Department of Electrical and Computer Engineering in Cornell Duffield College of Engineering and the paper’s co-senior author. “We’re showing that in spite of their size, adding more microrobots creates stronger flows and greater torque transfer.” The research published Feb. 25 in Science Advances. The lead author is Steven Ceron, Ph.D. ’22, now an assistant professor at the University of Michigan. More:

Gardeners experiment every time they sow a new vegetable, and sometimes it fails: blighted tomatoes, moth-eaten cabbage, plants that never flower. “That’s part of gardening,” said Noel Harradine, a master gardener volunteer with Cornell Cooperative Extension Wayne County, one of more than 100 CCE gardeners across the state working to take some trial and error out of the process by testing varieties to find what grows best in New York. Harradine’s work is part of CCE’s statewide Vegetable Variety Trial Garden program, a long-standing initiative to help New York gardeners choose the best-performing varieties for their regions. Across 37 counties this year, master gardener volunteers have sown select vegetables in CCE garden beds and are now collecting data and evaluating vegetables for taste, yield, and ease of growing. The observations are collected in a public web forum and shared with Cornell researchers and extension staff, as well as the sponsoring seed company. Read more:

As psychedelic drugs gain more support from the medical community as a potential treatment for severe depression – and with the U.S. government relaxing its regulatory constraints – there remains a vast gap in understanding how the drugs work on the brain. Alex Kwan, Ph.D. ’09, professor of biomedical engineering in Cornell Duffield College of Engineering, is at the center of a multidisciplinary investigation that is exploring the basic neurobiology and mechanics behind psychedelic compounds such as psilocybin.

A team of undergraduates from Cornell CALS and Cornell Duffield College of Engineering beat out 95 other teams to take the grand prize at The Farm Robotics Challenge with their invention: an autonomous robot that kills weeds with electricity. Their robot can travel through a vineyard or orchard without a human operator, zapping weeds with a small amount of electricity, saving labor and energy, and preventing crop loss, without the use of herbicides.

For over 20 years, Nancy Du, associate professor of pathology and laboratory medicine and the Rasweiler Family Research Scholar in Cancer Research at Weill Cornell Medicine, has researched how metastatic cancer arises. With a $500,000 grant over three years from the Congressionally Directed Medical Research Programs at the U.S. Department of Defense (DoD), she was poised to study how to prevent cancer from spreading to the bones of patients with estrogen receptor-positive breast cancer. But in April, a stop-work order brought her research to a halt. More at
