According to the National Oceanic and Atmospheric Administration, aquaculture in the United States represents a $1.5 billion industry annually. Like land-based farming, shellfish aquaculture requires healthy seed production in order to maintain a sustainable industry. Aquaculture hatchery production of shellfish larvae — seeds — requires close monitoring to track mortality rates and assess health from the earliest stages of life.  Careful observation is necessary to inform production scheduling, determine effects of naturally occurring harmful bacteria, and ensure sustainable seed production. This is an essential step for shellfish hatcheries but is currently a time-consuming manual process prone to human error.  With funding from […]

Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth’s surface, the planetary boundary layer (PBL) — the lowest layer of the troposphere — is actually the part that most significantly influences weather near the surface. In the 2018 planetary science decadal survey, the PBL was raised as an important scientific issue that has the potential to enhance storm forecasting and improve climate projections.   “The PBL is where the surface interacts with the atmosphere, including exchanges of moisture and heat that help lead to severe weather and a changing climate,” says Adam Milstein, a technical […]

We’ve all seen videos over the past few years demonstrating how agile humanoid robots have become, running and jumping with ease. We’re no longer surprised by this kind of agility—in fact, we’ve grown to expect it. The problem is, these shiny demos lack real-world applications. When it comes to creating robots that are useful and safe around humans, the fundamentals of movement are more important. As a result, researchers are using the same techniques to train humanoid robots to achieve much more modest goals.  Alan Fern, a professor of computer science at Oregon State University, and a team of researchers […]
