At CES 2023, IE discovered a cutting-edge bioreactor for the future of in-space dining.

The days of tang and freeze-dried ice cream are far gone in the world of space technology. To find ways to grow food in space, organizations, including NASA, JAXA, and the European Space Agency, are collaborating with the food business.

Interesting Engineering (IE) learned from a panel of experts at the Consumer’s Electronic Show (CES) 2023 (Jan .05) the kind of solutions being developed to provide humans food during extended space flight-and eventually, habitation. One particular solution that stood out, turns plastic into consumable food. Yup, you read that right.

The transport of mercury ions across intestinal epithelial cells can be studied for toxicology assessments by using animal models and static cell cultures. However, the concepts do not reliably replicate conditions of the human gut microenvironment to monitor in situ cell physiology. As a result, the mechanism of mercury transport in the human intestine is still unknown.

In a new report now published in Nature Microsystems and Nanoengineering, Li Wang and a research team in mechanical engineering and regenerative medicine in China developed a gut-on-a-chip instrument integrated with transepithelial electrical resistance (TEER) sensors and electrochemical sensors.

They proposed to explore the dynamic concept to simulate the physical intestinal barrier and mirror biological transport and adsorption mechanisms of mercury ions. The scientists recreated the cellular microenvironment by applying fluid shear stress and cyclic mechanical strain.

Plastics are ubiquitous in our society, found in packaging and bottles as well as making up more than 18% of solid waste in landfills. Many of these plastics also make their way into the oceans, where they take up to hundreds of years to break down into pieces that can harm wildlife and the aquatic ecosystem.

A team of researchers, led by Young-Shin Jun, Professor of Energy, Environmental & Chemical Engineering in the McKelvey School of Engineering at Washington University in St. Louis, analyzed how light breaks down polystyrene, a nonbiodegradable plastic from which packing peanuts, DVD cases and disposable utensils are made. In addition, they found that nanoplastic particles can play active roles in environmental systems. In particular, when exposed to light, the nanoplastics derived from polystyrene unexpectedly facilitated the oxidation of aqueous manganese ions and the formation of manganese oxide solids that can affect the fate and transport of organic contaminants in natural and engineering water systems.

The research, published in ACS Nano on Dec. 27, 2022, showed how the photochemical reaction of nanoplastics through light absorption generates peroxyl and superoxide radicals on nanoplastic surfaces, and initiates oxidation of manganese into manganese oxide solids.

Princeton Engineering researchers have developed a cost-effective way to use breakfast foods to create a material that can remove salt and microplastics from seawater.

The researchers used egg whites to create an aerogel, a versatile material known for its light weight and porosity. It has a range of uses, including water filtration, energy storage, and sound and thermal insulation. Craig Arnold, the Susan Dod Brown Professor of Mechanical and Aerospace Engineering and vice dean of innovation at Princeton, leads a lab that focuses on creating new materials, including aerogels, for engineering purposes.

One day, sitting in a faculty meeting, he had an idea.

Heparin has long been used as a blood thinner, or anticoagulant, for patients with blood clotting disorders or after surgery to prevent complications. But the medication remains difficult to dose correctly, potentially leading to overdosing or underdosing.

A team of Penn State researchers combined heparin with a protein fragment, peptide, to slow down the release of the drug and convey the medication directly to the site of a clot. They published their findings in the journal Small.

“We wanted to develop a material that can gradually deliver heparin over time rather than the current iteration that gets cleared from the body in a couple of hours,” said corresponding author Scott Medina, Penn State associate professor of biomedical engineering. “We also wanted to deliver the drug through the skin instead of through an IV.”

“Five strangers were pulled together” in an engineering challenge to find a solution to a real-world problem.

Engineering researchers of an innovative academy program have designed a Submersible Remotely Operated Vehicle (SROV) in a span of six weeks after accepting the U.K. Navy’s challenge.

“I was skeptical at first that we could pull off such an ambitious project within the timeframe,” said Dylan Brennan, project team lead, a nuclear graduate working for Jacobs.
