This is SCIENCE FRIDAY. I'm Flora Lichtman, filling in for Ira Flatow today. Last year, researchers reported a breakthrough in treating Alzheimer's disease. They'd found a drug that appeared to reverse the symptoms of Alzheimer's in mice. The drug was already on the market, approved by the FDA to treat a type of skin cancer, meaning Alzheimer's patients could ask their doctors for a prescription, and some did.

This is SCIENCE FRIDAY. I'm Flora Lichtman. You've likely heard of the legendary explorers Lewis and Clark, but maybe not of the U.S. Army explorer Stephen Harriman Long, an engineer who led a scientific expedition through the Great Plaines 15 years after Lewis and Clark.

His expedition traveled through Oklahoma, Kansas and Nebraska. And what did his crew make of America's Breadbasket? A place wholly unfit for cultivation or agriculture, they said. On a map, the explorers labeled the Great Plains as the Great American Desert.

In parts of the southeastern US, aggressive fire ants have been driven out by an even more recent arrival, the tawny crazy ant. Edward LeBrun, a researcher at the University of Texas at Austin, describes the newcomers and how one invasive species can out-invade another.

North Carolina State University biologist Rob Dunn and colleagues surveyed people's pillow cases, refrigerators, toilet seats, TV screens and other household spots, to learn about the microbes that dwell in our homes. Among the findings, reported in the journal PLoS One, homes with dogs had more diverse bacterial communities, and higher numbers of "dog-associated" bacteria.

Smartphones, tablets and computers could help seniors stay connected to their communities and families. But a hefty price tag, steep learning curves, and designs meant for younger eyes and hands could keep some older adults from logging on. Guests discuss the best ways for seniors to tackle new technology, and how devices can be adapted to accommodate older users.

In a speech at the National Defense University, President Barack Obama addresses the use of U.S. drones to target terrorists — including U.S. citizens — and his renewed efforts to close the military prison at Guantanamo Bay.

Writings from childhood — cards, stories and other notes — can hide for decades, like time capsules tucked away in boxes, old bedrooms, attics and journals. Writer Jim Sollisch talks about how old thank you notes from his youth foreshadowed his adult life.

Beijing continues to pressure its neighbors over strings of disputed areas in the South China Sea that reportedly hold massive deposits of oil and gas. The ongoing disputes raise serious questions about China's goals in the region and how the United States should address escalating tensions.

You've probably seen it in your inbox before: Someone who claims to have come into a fortune needs your help. You can share in the profits — if you send along a deposit or your bank account number. Boston Globe correspondent Finn Brunton talks about the history of the "Nigerian prince" or "419" scam, which actually got its start long before email.

PRESIDENT RONALD REAGAN: There you go again.

Monday's tornado tore through parts of Oklahoma City at 200 miles per hour and killed at least 24 people. Many more are missing orinjured. Guest host Jennifer Ludden talks to KOSU reporter Michael Cross and to meteorologist Paul Douglas about why it's so hard to track tornadoes.

Apple CEO Timothy Cook made a rare appearance on Capitol Hill on Tuesday, testifying after congressional investigators revealed that Apple avoided billions in taxes. Reporter Charles Duhigg of The New York Times and guest host Jennifer Ludden talk about how, as Duhigg writes, "technology giants have taken advantage of tax codes written for an industrial age."

It's graduation season, and that means 20-somethings and parents sitting through long commencement ceremonies while the older and wiser give advice. Here's comedian Stephen Colbert speaking at the University of Virginia.

Last week, the National Transportation Safety Board recommended lowering the blood alcohol content threshold for drunken driving from .08 to .05. The NTSB argues this could save millions of lives each year, but critics beg to differ. Some say lack of enforcement is the problem. Others point to our casual attitude about drinking and driving. Meanwhile, lowering the threshold could have implications for law enforcement, bartenders, maybe your dinner party.

This is TALK OF THE NATION. I'm Jennifer Ludden, in Washington. Population in America's big cities is surging, and more people are choosing to live alone. But where? As the demand for housing rises, some renters are opting to downsize their belongings and move to smaller spaces - much smaller. Imagine a single room no larger than many American closets and a community kitchen shared with multiple residents.

This is TALK OF THE NATION. I'm Jennifer Ludden in Washington. Neal Conan is away. Non-unionized fast food workers walked off the job in Milwaukee last week, demanding, among other things, a raise to $15 an hour. Their actions follow those of workers in four other cities this spring, part of what some are calling the new face of the labor movement, that is collective action outside of traditional union membership.

Generations of physicists have claimed that time is an illusion. But not all agree. In his book Time Reborn: From the Crisis in Physics to the Future of the Universe, theoretical physicist Lee Smolin argues that time exists--and he says time is key to understanding the evolution of the universe.
