Mystery of Big Data's Parallel Universe Brings Fear, and a Thrill

from the New York Times (Registration Required)

Not long ago, a woman in Tacoma, Wash., received a suggestion from Facebook that she "friend" another woman. She didn't know the other woman, but she followed through, as many of us have, innocently laying our cookie-crumb trails through cyberspace, only to get a surprise.

On the other woman's profile page was a wedding picture--of her and the first woman's husband, now exposed for all the cyberworld to see as a bigamist.

And so it goes in the era of what is called Big Data, in which more and more information about our lives--where we shop and what we buy, indeed where we are right now--the economy, the genomes of countless organisms we can't even name yet, galaxies full of stars we haven't counted, traffic jams in Singapore and the weather on Mars tumbles faster and faster through bigger and bigger computers down to everybody's fingertips, which are holding devices with more processing power than the Apollo mission control. Big Data probably knows more about us than we ourselves do, but is there stuff that Big Data itself doesn't know it knows? Big Data is watching us, but who or what is watching Big Data?

Earthquakes and Ancient Humans on the Island of Crete

Karl Wegmann, a geologist at North Carolina State University, may change how people view earthquake risks in the eastern Mediterranean. His study of the geology and archeological record of the island of Crete convinces him that the risk of a very large earthquake is less likely than geologists had believed.

That research also spawned an unexpected collaboration. Wegmann helped date the age of stone tools on Crete, artifacts that suggest that we Homo sapiens were not the first of our lineage to build or use boats.

In this podcast, Wegmann speaks with senior editor Cathy Clabby about his work studying the geology and prehistory of the beautiful island of Crete.

Wegmann spoke at Sigma Xi headquarters in February 2012.

Toward a Cure for AIDS

Current therapies are very good at keeping HIV under control, but they never completely cure it. That may change, if David Margolis and his colleagues are successful. As a physician and researcher at the University of North Carolina, Chapel Hill, Margolis studies the molecular biology of HIV infections. He is looking for ways to completely eradicate the virus from infected individuals.

In this podcast, Margolis speaks with associate editor Elsa Youngsteadt about what it will take to cure a person (or a mouse) of HIV.

Margolis spoke at Sigma Xi headquarters in January 2012.

Appalachian Coal Mining

Southern Appalachian forests are a global biodiversity hotspot. But they’re also rich with coal. Duke University ecologist Emily Bernhardt led a recent study that documents the long-term, widespread effects of surface coal mining on the region’s waterways.

In this podcast, Bernhardt speaks with associate editor Cathy Clabby about Appalachian ecosystems, and how they’re changing.

Bernhardt spoke at Sigma Xi headquarters in November, 2011.

Reflections on a Public Genome

Duke University geneticist Misha Angrist’s genome is a public document, thanks to his participation in Harvard’s Personal Genome Project. Angrist reflects on the medical and ethical implications of the project in his 2010 book, Here is a Human Being: At the Dawn of Personal Genomics.

In this podcast, he speaks with associate editor Cathy Clabby about his experience.

Angrist spoke at the Sigma Xi headquarters in October 2011.
