Haptic technology for touchscreens! NSF Science Now 31

The video covers four NSF-funded research projects. Geologists from the University of Illinois and Nanjing University discovered a distinct inner core within Earth's inner core using seismic energy. A Duke University study found high levels of ammonium and iodine in wastewater from oil and gas drilling, highlighting insufficient brine treatment in Pennsylvania. Engineers from UC Berkeley investigated metal fragments causing wildfires, aiming to improve fire prediction models. Researchers from Northwestern and Carnegie Mellon universities explored haptic feedback, revealing how the brain perceives tactile illusions, which could enhance virtual interfaces.
