At Ohio State, the race to reshape emergency rescue tech is on Future engineers are soaring to new heights as they design the next generation of autonomous emergency rescue vehicles. A group at The Ohio State University has created “STUART,” a Small Transportable Uncrewed Aerial Rescue Technology flight vehicle. The team — called The Sloopy Works — designed STUART as an entry for the GoAERO Prize, a...

Using moon dirt to build future lunar colonies Simulated lunar dirt can be turned into extremely durable structures, potentially paving the way to more sustainable and cost-effective space missions, a new study suggests. Using a special laser 3D printing method, researchers melted fake lunar soil – a synthetic version of the fine dusty material on the moon surface, called regolith simulant...

Emotional memory region of aged brain is sensitive to processed foods Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation in the aged brain – and the effect can happen fast, after just three days of poor eating. A new study suggests another dietary pitfall could have a similar damaging effect in a similarly short amount of time in older adults: a lack of ...

Researchers find satellite data can’t forecast future tremors Scientists have developed a method to assess whether tiny changes in Earth’s gravity can be used to predict oncoming earthquakes. Their conclusion: It can’t, which refutes a hypothesis which researchers thought would provide hope for better warnings. As one of the most mysterious of our planet’s natural disasters, earthquakes’ location a...

Researchers want a better whiff of plant-based proteins Off-putting smells can make even the healthiest of foods unpalatable. In a new study, researchers have developed a way to remove unpleasant aromas from plant-based proteins to make them smell more appealing. They did so by designing a two-step fermentation process to counter the odors that typically form during cultivation and extraction. The st...

Signal carriers from cells embedded in tissue send short-range messages A new study may change the way scientists think about the distance traveled by tiny bubbles carrying signals between cells that are embedded in tissue. These particles, called extracellular vesicles, are known to safely carry signaling cargo as a communication method between cells in bodily fluids and within tissue, and to influence health and d...
