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.
This weekend the American Medical Association will kick off its annual exercise in medical democracy.
The group's House of Delegates will meet in Chicago to vote on resolutions that range from a demand that private insurers pay doctors at least as much as Medicare does to a call for federal legislation affirming the right of doctors to talk about gun safety with patients.

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.
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.
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.
Anyone who has taken some time on Earth Day to contemplate the planet has my next guest to thank. Danis Hayes was the first national coordinator for Earth Day back in 1970, and if I might insert a personal note, Earth Day back in 1970 was also the anniversary of my first science story I ever did. So this is very interesting, and I'm very happy to have as my guest today Denis Hayes, who is, and as I say, he's head of the Solar Energy Research Institute under President Jimmy Carter.
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.
