No, they’re not otherworldly or apparitional — they’re just insects. Blue ghost fireflies (Phausis reticulata), native to the region, begin their mating season as spring slides into summer, usually around the beginning of June, although they’re already starting to appear this year, says Jennifer Frick-Ruppert, a professor of biology and environmental science at Brevard College in North Carolina.

Do we rely too much on GPS?

May 22, 2016

So many parts of our modern world rely on GPS, or the Global Positioning System: driving, timekeeping military operations, crop harvesting, financial deals. Even, author Greg Milner argues, the way we think has been affected.

Milner says the ubiquity of GPS in our daily lives is what got him interested in the technology.

Contestants on the reality TV show "The Biggest Loser" put in a gargantuan effort to lose weight: They diet rigorously, exercise for hours a day, and compete with each other to completely change their bodies. And many do change their bodies, quickly losing 100 pounds, 200 pounds — or more.

But what happens after? It turns out that, like many people who lose weight, maintaining that smaller frame is hard, even for those whose bodies changed so rapidly and completely.

Is a human smarter than an octopus? 

“It’s really the wrong question to ask,” says primatologist Frans de Waal. “Because I’m smarter than an octopus in things I’m good at, like language and technology. But the octopus is smarter than me in many other ways.”
