Ocean Roundup: New Coral Reef Species Discovered, Seals Found to Spread Tuberculosis 6,000 Years Ago, and More
- Seals may just be the culprit in having spread tuberculosis from Africa to the New World 6,000 years ago. A new study found that seals contracted the disease when they crawled ashore on African beaches to raise their young, and then brought it to South America, where hunters became exposed.

One plan involves building up almost 70 miles of barrier islands by dredging sand and mud, including some from the bottom of the Mississippi River, and depositing it onto the outer shores of the islands, a process that would normally require years of environmental assessment.
Sediments from the river are likely to be contaminated with a host of other chemicals, like mercury, which could add insult to injury in the already badly contaminated Gulf waters.
Some of these islands are home to bird and wildlife sanctuaries, including the Breton National Wildlife Refuge. The plan may not work because the barrier islands have shrunk significantly, in part as a result of human engineering that has altered the flow of Mississippi for a variety of reasons -- including in efforts to facilitate oil and gas production.
