Protected areas of defined geographic zones can slow biodiversity loss and bolster conversation efforts, but they may have unintended impacts on the diets of children who live nearby, according to new research from scientists at Penn State.

Pinch a cushion to dim the lights or get a tap on the shoulder from your backpack when it’s time to turn left – this responsive new tech may be ready to roll out within a year or two. It’s called HydroHaptics, and it has been developed at the University of Bath in the UK.

In this week’s AIP Advances, researchers explore gemstone polishing waste as a possible additive in cement, aiming to keep silicon carbide waste out of landfills and reduce emissions from the cement industry. The team tested chemical reactions at the molecular level, as well as microscale characteristics, such as microcracks and pore size, and macroscale outcomes, such as material strength and thermal and conductive properties. The added gemstone polishing waste enhanced thermal conductivity and reduced electrical resistivity in the modified cement.

Current battery management systems might report a car is 40% charged but drivers have to guess whether they can go 100 kilometers over hills with the heater running. Engineers at the University of California, Riverside want to take the guesswork out of it.
