In praise of boredom: Researchers dish on the brain benefits of idle time

7 hours ago

When’s the last time you were really, truly bored?

In an age of smartphones, social media and a 24-hour news cycle, it might be tough to recall the last time you found yourself turning your attention to absolutely nothing. But that mental downtime, it turns out, is when a very important part of your brain gets to work.

Around the country, hundreds of millions of dollars have been spent to buy back individual homes from people whose properties have flooded repeatedly. But buying out a whole neighborhood is uncommon. Louisiana’s 2016 flood seems to be changing that for two communities. In Pointe Coupee and Ascension parishes, a buyout program first used in neighborhoods after Superstorm Sandy may offer a new option to homeowners who have lived with escalating flood risk for decades.

It’s been just over 70 years since two atomic bombs devastated the Japanese cities of Hiroshima and Nagasaki, the first and last time that nuclear weapons have been used in warfare.

“Technically, a glow worm is actually a glowing maggot, but that doesn't sound as romantic," says Miriam Sharpe, a biochemistry researcher at the University of Otago in New Zealand.

We’re the biggest culprits behind wildfires. Now what?

In the United States, this year’s wildfire season has been wild, to say the least. Roughly 50,000 fires have scorched more than 8.5 million acres across the country, hitting the Pacific Northwest, California and Montana particularly hard.

In the recent film “Rememory,” an inventor has built a device that can extract memories from the brain. There’s more to the story — a murder, for one, and an amateur sleuth played by Peter Dinklage — but let’s pause here.
