This Is Your Brain on Nature

When you head out to the desert, David Strayer is the kind of man you want behind the wheel. He never texts or talks on the phone while driving. He doesn’t even approve of eating in the car. A cognitive psychologist at the University of Utah who specializes in attention, Strayer knows our brains are prone to mistakes, especially when we’re multitasking and dodging distractions. Among other things, his research has shown that using a cell phone impairs most drivers as much as drinking alcohol does.

Strayer is in a unique position to understand what modern life does to us. An avid backpacker, he thinks he knows the antidote: Nature.

Cats crossed continents to be close to us, says gene study

Cats like to think they don’t need us, but a new study into feline genetics has indicated that the global kitty population only boomed when they moved in with humans. The research, presented last week and reported by Nature, seems to show two distinct waves of growth in cat numbers: first around 10,000 years ago as humans first started cultivating crops, and second as we started taking to the seas.

CAT FAMILIES FROM EGYPT ENDED UP IN BULGARIA

The researchers behind the study sequenced DNA from more than 200 cats of various generations discovered in tombs, burial sites, and other archaeological sites, from as far back as 15,000 years ago, to animals born in the 1700s. Even among this limited sample, they found links in mitochondrial DNA, genetic information passed down through the maternal line only — suggesting that cat families had either moved or been taken near to human civilizations. This mitochondrial connection was spotted between wild cats found in the Middle East and creatures discovered close to the fertile east Mediterranean, a region well-known for its early agriculture. Researchers also found connections between cats that lived millennia later, linking mummified kitties discovered in Egyptian tombs with cats found as far away as Bulgaria, Turkey, and sub-Sarahan Africa.
