A day that began with the Anonymous hackers posting a nearly 17-minute recording of a conference call between officials of the FBI and Scotland Yard has been followed with some tweeted taunting of law enforcement and the news media, and the hacking of websites for the Greek Ministry of Justice, Boston Police Department and lawyers who defended a U.S. Marine at the center of the killing of 24 unarmed Iraqi civilians.

In an interview Thursday, Mitt Romney said he "misspoke" when he infamously said earlier in the week that he was not concerned about the very poor because they had a safety net, and the very rich but, instead, was focused on the middle class.

Speaking of the CNN interview that has caused Romney a world of trouble, the Republican presidential frontrunner told Jon Ralston of the Las Vegas Sun during an interview program called Face to Face:

In That's Disgusting: Unraveling the Mysteries of Repulsion, psychologist Rachel Herz discusses the origins of disgust — what she calls the 'instinct that's learned' — and why humans turn up their noses at smelly feet but devour expensive cheeses cultured with some of the very same stinky bacteria.

Amyloid plaques and tangles of protein in the brain are two of the key signs of the form of dementia known as Alzheimer's disease. In new work reported in the journal PLOS One, researchers tracked the spread of tangles of tau protein from neuron to neuron in the brains of mice. Study co-author Karen Duff of the Columbia University Medical Center discusses the findings.

NASA's iconic images of Earth from space date back to the late 1960s--with snapshots taken by Apollo astronauts. The modern "blue marble" images are captured by machines and they're not photos. They're datasets collected by instruments aboard satellites and then translated into imagery on the ground.

As it circles Earth, NASA's Interstellar Boundary Explorer hunts for particles streaming in from beyond the solar system. It has intercepted hydrogen, helium, neon and oxygen atoms. IBEX principal investigator Dave McComas discusses how the abundance of those atoms hints at the Milky Way's composition.

Unmanned Aerial Vehicles (UAVs) are replacing boots on the ground in some wars. Commercially, UAVs are being used for things like crop-dusting and flood mapping. Experts discuss advances in drone technology and how to address legal and privacy concerns that stem from their use.

Reporting in PLoS Biology, researchers write that they were able to correlate words a person was hearing to specific electrical activity in the brain. Study co-author neuroscientist Robert Knight discusses future applications of this research and concerns that it amounts to mental wiretapping.

NPR's Business News starts with a reversal from the Komen Foundation. The Susan G. Komen For The Cure Foundation has just announced that it will not pull its funding for Planned Parenthood after all. The breast cancer charity endured a massive backlash when it announced, earlier this week, it would no longer give Planned Parenthood money for breast cancer screening. NPR's Julie Rovner joins us to explain the turnaround. And Julie, what exactly did the Komen Foundation say this morning?

Saying officials have undertaken yet another campaign of "bullying and harassment" of its Persian service staff, the BBC called on the Iranian government to "repudiate the action of its officials."

In a blog post, the BBC's Director General Mark Thompson also called on the international community to "put maximum pressure on Iran to desist in this campaign of intimidation, persistent censorship and a disturbing abuse of power."
