NSF Science Now: Episode 31

The video explores various scientific studies funded by the National Science Foundation. It begins with a study on Earth's inner core, revealing a distinct inner core within it, which could provide insights into Earth's formation. Another study highlights the presence of hazardous chemicals in wastewater from oil and gas drilling, emphasizing the need for better treatment practices. Research on wildfires identifies metal fragments as a cause, with experiments aiming to improve fire prediction models. Lastly, a study on haptic feedback uncovers how the brain perceives tactile illusions, potentially leading to advanced touch technology.
