For many people, fireflies lighting up backyards is a sign of summertime. The thrill of catching them in a jar and releasing them back into the wild is a childhood pastime. But if you have noticed a decline in fireflies over the years, you’re not alone. Virginia Tech entomologist Eric Day explains why climate and urban development are playing a big role in the decreasing numbers.
Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.
