What if we told you that the secret to healthier soil, cleaner ecosystems, and smarter farming isn’t buried in a high-tech lab—but hidden in the data behind crop residues, wood chips, and food waste?
Meet the future of sustainable agriculture: a powerful new machine learning tool that can predict exactly how much biochar—a carbon-rich, soil-boosting material—can be made from any type of biomass, and how much nitrogen, phosphorus, and potassium it will contain. No crystal ball needed. Just smart science, powered by data.
In a time of tariffs and political trade disputes, new UBC Okanagan research shows that it’s not what you know but who you know.
And how well you treat them.
The research demonstrates that strong and strategic international alliances—not just diversification—are key to protecting supply chains from political trade disruptions.
WPI Assistant Professor Nitin Sanket has received a $704,908 National Science Foundation (NSF) Foundational Research in Robotics grant to develop sound-based navigation systems that enable tiny aerial robots to operate in environments where cameras and light sensors fail, such as smoke, dust, or darkness. Drawing inspiration from how bats use echolocation, Sanket’s project combines bio-inspired design, deep learning, and sensor fusion to create lightweight, energy-efficient drones capable of autonomous navigation in challenging conditions—advancing robotics for applications in disaster response, environmental monitoring, and search and rescue.
Researchers from the USC Neurorestoration Center and the California Institute of Technology (Caltech) have built a simple, noninvasive device for measuring blood flow in the brain, by adapting a technique currently used in animal studies known as speckle contrast optical spectroscopy (SCOS). It works by capturing images of scattered laser light with an affordable, high-resolution camera— tiny blood cells pass through a laser beam, and the way the light scatters allows researchers to measure blood flow and volume. The device has already been tested with humans in small proof of concept studies demonstrating the tool’s utility for assessing stroke risk and detecting brain injury. In the current study, Liu and his team sought to confirm that SCOS is truly measuring blood flow in the brain, rather than in the scalp, which also contains many blood vessels. Liu’s team took an innovative approach: By temporarily blocking blood flow to the scalp, they confirmed that SCOS readings were indeed measuring signals from blood vessels in the brain. Readings from 20 participants showed that positioning the detector at least 2.3 centimeters away from the laser source provided the clearest measurement of brain blood flow. Beyond advancing research, the study helps confirm the clinical potential of SCOS for detecting and responding to stroke, brain injury and dementia.
