Rice researchers and collaborators have developed a system to camouflage heart rate from radar-based surveillance.

In a new analysis led by investigators from the University of Utah and the University of Pennsylvania, researchers examined what the real-world impact of this technology might look like if deployed broadly across the U.S. adult population.

A new smart platform invented by Purdue University researchers to wirelessly monitor subsoil health could change the landscape of agricultural sensing systems. The invention addresses a critical need in agriculture nationwide: the efficient use of water, fertilizers and pesticides. Due to the variability of soil conditions across large fields, applying uniform amounts of these inputs can lead to significant waste, increasing costs for farmers and causing environmental harm if nutrient runoff reaches water systems.

MIT engineers identified a common polymer whose thermal conductivity changes quickly and reversibly when the material is stretched. The material could be used to engineer systems that adapt to changing temperatures in real-time, such as switchable fibers woven into apparel.
