Now, for many of us, we first heard about the Ebola virus from the movie "Outbreak," Dustin Hoffman trying to contain an outbreak of an Ebola-like virus in a small California town.

Does the pain we feel from rejection and loss have the same effect as physical pain? How does our brain respond to social interactions? In his new book Social: Why Our Brains Are Wired to Connect , social neuroscientist Matthew Lieberman describes the biology behind how our brains engage with the social world.
Writing in Science , researchers say a 1.8 million-year-old skull found in Dmanisi, Georgia indicates that early humans may have evolved from a single lineage rather than from multiple species. Anthropologist Adam Van Arsdale tells us what this could mean for the way we view human evolution.

Earlier this month, plans for a new marine theme park were announced for the town of Taiji, Japan. Sometime within the next five years, if the plans come to fruition, tourists will be able to observe and swim with dolphins and small whales. Then, while still in the park, they can eat dolphin and whale meat, all the time knowing that their park fees support the slaughter of dolphins.
This year is the 40th anniversary of the OPEC oil embargo - an event that has shaped our nation's politics and the cars we drive ever since. In 1973, the Arab world decided to cut oil exports to punish nations that supported Israel during its war with Egypt and Syria. While the embargo only lasted several months, it triggered an energy crisis that lasted for years. NPR's Richard Harris reports on the ways we are still feel those effects today.
