Soft, 3D-Printable Robot Exploits Temperature Changes in Water to Self-Propel

Imagine fleets of compact, self-propelling robots quietly making their way through the world's oceans, surveilling marine life and monitoring conditions, each one moving without a power supply or even an engine. It may sound like science fiction, but thanks to a team of researchers from ETH Zurich and Caltech led by Professor Kristina Shea , this new concept for self-propelling, swimming robots that exploit in-water temperature fluctuations to move, has now undergone a successful proof-of-concept study. “We had already developed 4D printed deployable structures that use the combination of shape memory polymer strips and tunable, bi-stable joints to reconfigure themselves from flat structures into different forms,” explains Professor Shea.

Developing Water Quality Criteria for Toxicity of Metals and Metalloids Worldwide

The presence of metals and metalloids in marine ecosystems is an environmental concern worldwide. Elevated concentrations of metals like cadmium, chromium, mercury, and nickel can harm marine animals, not to mention the humans who eat them. This means that developing water quality criteria (WQC) or environmental safety limits for a range of metals and metalloids is critical to public and environmental health. This need to know the maximum safe levels of these elements is also typically a precursor to creating protective regulations.

From Butterflies to Birds: Five Rivers MetroParks Fauna Get Thorough Environmental Monitoring

Five Rivers MetroParks covers 16,000 acres of diverse lands in southwestern Ohio. The “five rivers” in its name refer to the Miami River, Stillwater River, Mad River, Twin Creek and Wolf Creek which give character to the region. Grace Dietsch has been involved in many of Five Rivers MetroParks environmental monitoring programs in her four years as Five Rivers MetroParks Biologist. Butterflies, deer, salamanders, fish, snakes and birds are some of the many species being monitored on MetroParks grounds. While MetroParks staff members compile the data, volunteers sometimes provide a significant portion of the environmental monitoring data itself. “We try to contribute to research and management decisions with the data we gather,” explains Dietsch.
