Grant aims to improve environmental education

A Virginia Tech professor is leading a study on STEM-based environmental education programs to determine how to promote positive learning outcomes for students. The research, funded by the National Science Foundation, will observe 500 single-day field trips and analyze their characteristics to identify factors linked to better outcomes.

New method gives robust transistors

Scientists at Linköping University and SweGaN have developed a new method to fit together layers of semiconductors, resulting in high-breakdown thin GaN transistors. The transistors can withstand high voltages due to the gradual absorption of strain between layers.

'Locally grown' broccoli looks, tastes better to consumers

Consumers rated locally grown New York broccoli as better-looking and tasting than a California variety, even though it didn't look more appealing. The study suggests that labeling products as local can improve their perceived value and quality, regardless of actual differences in taste or appearance.
