Nell Greenfieldboyce is a NPR science correspondent.

With reporting focused on general science, NASA, and the intersection between technology and society, Greenfieldboyce has been on the science desk's technology beat since she joined NPR in 2005.

In that time Greenfieldboyce has reported on topics including the narwhals in Greenland, the ending of the space shuttle program, and the reasons why independent truckers don't want electronic tracking in their cabs.

Much of Greenfieldboyce's reporting reflects an interest in discovering how applied science and technology connects with people and culture. She has worked on stories spanning issues such as pet cloning, gene therapy, ballistics, and federal regulation of new technology.

Joe Palca is a science correspondent for NPR. Since joining NPR in 1992, Palca has covered a range of science topics — everything from biomedical research to astronomy. He is currently focused on the eponymous series, "Joe's Big Idea." Stories in the series explore the minds and motivations of scientists and inventors.

Palca began his journalism career in television in 1982, working as a health producer for the CBS affiliate in Washington, DC. In 1986, he left television for a seven-year stint as a print journalist, first as the Washington news editor for Nature, and then as a senior correspondent forScience Magazine.

Whether economic sanctions can force a government to change course is far from clear, but Iran should be a good test case.

A European Union embargo on Iranian oil took full effect this week, complementing U.S. measures that have grown much more severe in recent weeks. Other Western sanctions now in place target Iranian banks, foreign companies that provide shipping insurance for Iranian oil tankers, and foreign firms that invest in the Iranian oil industry.

If it hasn't happened to you, count yourself as lucky. For many people, eating ice cream or drinking an icy drink too fast can produce a really painful headache. It usually hits in the front of the brain, behind the forehead.

The technical name for this phenomenon is cold-stimulus headache, but people also refer to it as "ice cream headache" or "brain freeze."

The good news is that brain freeze is easy to prevent — just eat more slowly. The other bit of good news is these headaches don't last very long — a minute at the outside.

In politics, money talks. And money from gay and lesbian donors is talking louder than ever in this election cycle.

That's partly a result of President Obama endorsing same-sex marriage, and it's partly because Republicans are starting to see contributions as well.

That's a huge change from just a few decades ago.

There are few opposition leaders who are welcomed abroad with the same pomp and ceremony as heads of state. But that's the sort of star treatment lavished on Aung San Suu Kyi, opposition leader of Myanmar, also known as Burma, on her three-week tour of Europe.

But pressure is increasing on her to address simmering political crises at home, and to move her country's democratic changes forward.

In Geneva, Oslo, Dublin, London and Paris, Suu Kyi issued eloquent pleas for ethical foreign investment in Myanmar and foreign support for her country's ongoing reforms.
