In the 10 years since sagging power lines in Ohio sparked a blackout across much of the Northeastern United States and Canada, utility engineers say they have implemented measures to prevent another such event in the country's electric grid.
But there is one disaster scenario for which the power companies are still unprepared: a massive attack on the computer networks that underlie the U.S. electric grid.
It's clear from Dick Knox's story just now that there are a lot of caveats that come along with the study of finasteride. One physician, Dr. Michael LeFevre, certainly feels that way. Dr. LeFevre is a professor at University of Missouri Medical School, and he's co-vice chair of the United States Preventive Services Task Force. He joins us now from Columbia, Missouri. Welcome.

Federal prosecutors have charged two former JPMorgan Chase traders with securities fraud. The two men worked in London. And they are part of the so-called London Whale case, which cost the company more than $6 billion. U.S. officials say the men lied about the value of some derivatives trades to cover up mounting lawsuits. More from NPR's Jim Zarroli.
Former Congressman Jesse Jackson Jr. was sentenced to 30 months in prison today for using campaign funds to buy luxury goods. His wife also received a year in prison for filing false tax returns. Prosecutors called their joint crimes one of the worst abuses of campaign finance laws in recent memory. NPR's Jennifer Ludden was at the courthouse here in Washington, D.C.
Wind turbines at the Kahuku wind farm on Oahu's North Shore in 2011. Hawaiian energy managers are hoping to build stronger connections with customers to better manage renewable sources of energy on the grid.
The electricity system is experiencing growing pains these days. But it's not only demand for electricity that's expanding — it's the sources of electricity, particularly unpredictable kinds, like wind farms and solar panels.
And grid operators know that we're just at the beginning. States are requiring more renewable power to fight climate change, and it may be the customers who will play a big role in helping grid operators manage these clean, but finicky, sources of power.
Researchers say a cheap, generic pill called finasteride prevents almost 40 percent of low-grade prostate cancers without increasing the risk of dying from more aggressive tumors.
New evidence points to the drug as a potentially safer way to deal with prostate cancers that now get more intense treatment. Many prostate cancers that aren't destined to cause men serious health problems are often treated with surgery or radiation.

Congressional Republicans agree that the new federal health care program should be ended. But they are finding themselves bitterly divided over how.
They have tried dozens of times to repeal it. Now, some GOP lawmakers want to block all money for Obamacare in a stopgap spending bill that must be approved next month to prevent the government from shutting down on Oct. 1. But other Republicans say that won't work and may well backfire.
One of the world's most trusted sources for news is back up, after an internal outage knocked it out for nearly two hours on Wednesday morning. The New York Times' main site and mobile app went down a little after 11 a.m. ET, when users who tried to visit received a "Service Unavailable" message.
The news organization's Twitter account sent this message, before the site returned:
Imagine a ship carrying goods in containers that, if lined up, would stretch around 11,000 miles long, or nearly halfway around the planet. Rose George spent several weeks aboard one such ship as research for her new book, Ninety Percent of Everything: Inside Shipping, the Invisible Industry That Puts Clothes on Your Back, Gas in Your Car and Food on Your Plate.
