After Hinckley, States Tightened Use Of The Insanity Plea

The insanity ruling that sent President Ronald Reagan's would-be assassin John Hinckley, Jr., to a government psychiatric hospital rather than prison was handed down 34 years ago, but its repercussions still affect hundreds, if not thousands, of people who commit a crime and also have mental illness.

Writing Data Onto Single Atoms, Scientists Store The Longest Text Yet

A group of nano-scientists has discovered a way to arrange individual atoms to store and rewrite data 500 times more efficiently than the best hard drives on the market.

A team of researchers from the Netherlands, Portugal and Spain has made a major breakthrough in so-called atomic memory — an approach that stores one bit of data on each atom with a goal of creating a new kind of tiny data storage device of the future.

Oyster Archaeology: Ancient Trash Holds Clues To Sustainable Harvesting

Times are tough for Chesapeake oysters.

For one thing, they used to be bigger. "If you look at what people were saying back in the 1600s and 1700s about oysters, people had to cut them in half before they could even eat them," says Denise Breitburg, an ecologist with the Smithsonian Environmental Research Center.

Chelsea Clinton stands behind her mother after Hillary Clinton won the New York Democratic primary in April.

Chelsea Clinton Looks To Help Her Family Return To The White House

America's first image of Chelsea Clinton was as a curly-haired preteen girl with braces who shied away from the public stage while her father was president in the 1990s.

More than two decades later, the now 36-year-old mother of two will voluntarily step into the spotlight to introduce her own mother as her family seeks a return to the White House.

President Obama and Hillary Clinton stand together on stage on the third day of the Democratic National Convention in Philadelphia.

Convention Speeches Soar, Raise A Question: Can Clinton Connect With Ordinary People?

The third night of the 2016 Democratic convention scaled several major peaks: President Obama gave, perhaps, the best-written oration of his career. Vice President Joe Biden gave, perhaps, his last national convention address, and his prospective successor, Tim Kaine, gave his first.

Clinton was the first student to deliver a commencement speech at Wellesley College in 1969. Her criticism of Sen. Edward Brooke's speech received national attention.

Taking On A U.S. Senator As A Student Propelled Clinton Into The Spotlight

Hillary Rodham's 1969 commencement address at Wellesley College did not stand out because of what she said.

It stood out because of how she said it, and because she said it at all. This is a story not about words, but about context.
