Since public revelations that the National Security Agency is collecting telephone records and reviewing Internet communications in the U.S. and abroad, officials have been making the case that the programs are vital. They argue that the tactics match the new ways terrorists are planning and communicating.
There was a time when America's enemies conspired face-to-face, or communicated through couriers, or by leaving messages for each other somewhere. But in the digital age, that has changed.
This week, the U.S. Fish and Wildlife Service proposed a new rule that would extend "endangered species" protections to chimpanzees held in captivity. Nearly half of all the chimps in the U.S. live in research facilities, and the regulation changes would make it more difficult to use these animals in medical experiments.
Australian archaeologists using remote-sensing technology have uncovered an ancient city in Cambodia that has remained hidden for more than a millennium under dense jungle undergrowth.
The discovery of Mahendraparvata, a 1,200-year-old lost city that predates Cambodia's famous Angkor Wat temple complex by 350 years, was part of the Hindu-Buddhist Khmer Empire that ruled much of Southeast Asia from about 800 to 1400 A.D., during a time that coincided with Europe's Middle Ages.

The diet world has a new golden child: green coffee extract.
A "miracle fat burner!" "One of the most important discoveries made" in weight loss science, the heart surgeon Dr. Mehmet Oz said about the little pills — which are produced by grinding up raw, unroasted coffee, and then soaking the result in alcohol to pull out the antioxidants.
We are broadcasting today from the Pacific Science Center in Seattle. And just steps away from this building, right outside is something that should be familiar to anyone who's ever received a postcard from Seattle or taken home a pen or a glass or anything tchotchke of any kind. And it's the Space Needle, built in connection with the 1962 World's Fair. It is an iconic part of the Seattle skyline.
Think for a minute about the victims of climate change. You might envision the polar bear, right? You see a lot of that in the news, atop a block of melting ice or - where there's no ice to grab onto, or the great ice sheet covering Greenland drip, drip, dripping away, or the tiny island of Tuvalu whose people and beaches might soon be swallowed by rising seas.
This is SCIENCE FRIDAY, I'm Ira Flatow. He's been called Mayor McSchwinn for riding his bicycle to work. He's pledged to turn his town of Seattle into a model for what one city can do to lower its carbon footprint, and for good reason. As the climate changes, coastal cities like Seattle are challenged by rising sea levels.
This is SCIENCE FRIDAY. I'm Ira Flatow. Your brain has nearly 100 billion neurons, and one of my next guests compares that complexity to the Amazon rainforest. In fact, he says there about as many trees in the Amazon as there are neurons in your brain. Think about what the Amazon looks like for a second.
This is SCIENCE FRIDAY. I'm Ira Flatow. Yesterday, the Supreme Court ruled that human genes cannot be patented. The case involves a dispute over patents held on the BRCA1 and the BRCA2 genes, the so-called breast cancer genes; and tests a company, Myriad Genetics, used to look for mutations to those genes.
