With Rising Temperatures, Infrastructure Falters

IRA FLATOW, HOST:

Exactly a year ago this week, a video on YouTube went viral. It was called "Heat Buckles Highway, SUV Goes Airborne." A road in Wisconsin buckled so badly from the heat that it sent cars flying. Well, this year, the buckling continues. But if you're in certain parts of the country, you don't need me to tell you that. It's hot, and I'm not going to use that but-it's-a-dry-heat line, either.

Originally published on Tue July 9, 2013 11:37 am

Say you're in Midtown Manhattan at rush hour. You need to go a mile uptown, and you can't find a cab. A pedicab, a taxi-bicycle hybrid (like the one in the picture) may not be a bad option.

Riding through the middle of Manhattan on the back of a bike, dodging buses and cabs, feels like the Wild West of transportation options. The pricing feels that way too: Unlike buses or cabs, pedicabs don't charge a set fee. It's whatever the rider and the driver agree to. And, like in the Wild West, innocents often get fleeced.

Shootings Reported At Demonstrations In Egypt

Transcript

RENEE MONTAGNE, HOST:

It's MORNING EDITION, from NPR News. I'm Renee Montagne.

This is a week when Egypt is divided on what democracy means. In what amounted to a second uprising, millions of Egyptians poured into the streets to demand that their democratically elected president step down. When he balked, the army ousted Mohamed Morsi, which led his supporters to say it is a dark day for democracy there. Today, thousands of Morsi supporters are out protesting that military coup, in demonstrations that have reportedly turned violent.

Can White Blood Cells Spread Cancer?

Originally published on Fri July 5, 2013 12:55 pm

Transcript

IRA FLATOW, HOST:

This is SCIENCE FRIDAY. I'm Ira Flatow. White blood cells are part of our body's defense system. Their job is to attack invaders, and one of the first white blood cells sent out is the neutrophil. These neutrophils put out a trap to capture and destroy the invaders. But here's where it gets interesting, because in a new study, researchers say they have shown that these nets might actually activate and spread the cancer cells. It's the exact opposite of what you want. But there may be a way to counteract this problem.

Archaeologists digging in the foothills of Iran's Zagros Mountains have discovered the remains of a Stone Age farming community. It turns out that people living there were growing plants like barley, peas and lentils as early as 12,000 years ago.

The findings offer a rare snapshot of a time when humans first started experimenting with farming. They also show that Iran was an important player in the origin of agriculture.
