Here are some of the most interesting research papers to have appeared in top science journals last week. (Subscribe to Science For All, our weekly newsletter, where we aim to take the jargon out of science and put the fun in. Click here.) Multipurpose herb Catnip ( Nepeta cataria), a garden herb known for its hallucinogenic effects on domestic cats, is also used to ward off insects, especially mosquitoes. A new study has now decoded how the plant does this. The researchers found that Catnip and its active ingredient Nepetalactone activates an irritant receptor called TRPA1. ....
Quick and Dramatic Transformation of the Bahamas Pete J van Hengstum and his team of researchers drew their new environmental conclusions from evidence gathered at the Blackwood Sinkhole , which they explained in the paper holds near-perfectly preserved organic materials from the last 3,000 years. Using core samples and radiocarbon dating , the team examined charcoal deposits from human fires that they say dated to “thousands of years ago, according to PNAS. This information helped them to determine that the first settlers arrived in the Bahamas much earlier than previously thought. Hengstum explained that the oldest archaeological sites in the southernmost Bahamian archipelago are found on the Turks and Caicos Islands and these indicate human arrival around 700 AD. Previous evidence suggested it may have taken hundreds of years for the Lucayans to move through the Bahamian archipelago that spans about 500 miles (894 km).

Study: Bahamas Were Settled Earlier Than Believed Humans were present in Florida by 14,000 years ago, and until recently, it was believed the Bahamas – located only a few miles away – were not colonized until about 1,000 years ago. But new findings from a team including a Texas A&M University at Galveston researcher prove that the area was colonized earlier, and the new settlers dramatically changed the landscape. Peter van Hengstum, associate professor in the Department of Marine and Coastal Environment Science at Texas A&M-Galveston, and colleagues have had their findings published in Researchers generated a new environmental record from the Blackwood Sinkhole, which is flooded with 120 feet of groundwater without dissolved oxygen. This is important because it has pristinely preserved organic material for the last 3,000 years. Using core samples and radiocarbon dating, the team examined charcoal deposits from human fires thousands of years ago, indicating that ....
New research finds that people settled the Bahamas earlier than scientists thought. Humans were present in Florida by 14,000 years ago, and until recently, it was believed the Bahamas located only a few miles away were not colonized until about 1,000 years ago. The new findings, however, prove that the area was colonized earlier, and the new settlers dramatically changed the landscape. As reported in the Proceedings of the National Academy of Sciences, researchers generated a new environmental record from the Blackwood Sinkhole, which is flooded with 120 feet of groundwater without dissolved oxygen. This is important because it has pristinely preserved organic material for the last 3,000 years. Using core samples and radiocarbon dating, the team examined charcoal deposits from human fires thousands of years ago, indicating that the first settlers arrived in the Bahamas sooner than previously thought. ....
