Scientists Reconstruct Pre-Columbian Human Effects on the Amazon Basin

Findings overturn idea that the Amazon had large populations of humans that transformed the landscape

Small, shifting human populations existed in the Amazon before the arrival of Europeans, with little long-term effect on the forest.

That’s the result of research led by Crystal McMichael and Mark Bush of the Florida Institute of Technology (FIT). The finding overturns the idea the Amazon was a cultural parkland in pre-Columbian times with large human populations that transformed vast tracts of the landscape.

The Amazon Basin is one of the highest biodiversity areas on Earth. Understanding how it was modified by humans in the past is important for conservation and for understanding the ecological processes in tropical rainforests. (more…)

Put a cork in it

Paper details use of natural material cork for quiet sandwich composites

Cork, known for its use in such low-tech applications as wine bottle stoppers and bulletin boards, now shows promise as the core material in composite sandwich structures for use in high-tech automotive, aircraft and energy applications. (more…)

Global Science: U.S. is Still in The Game

ANN ARBOR, Mich.— Globalization is a benefit to U.S. scientific achievement, not a threat. That’s the conclusion of a new book that weighs the evidence from a number of recent surveys to answer its title question: “Is American Science in Decline?”

American science is in good health, according to the book’s authors, sociologists Yu Xie of the University of Michigan and Alexandra Achen Killewald of Harvard University.

Although there are areas of concern, they maintain that traditional American values will help the nation maintain its strength in science for the foreseeable future, and that globalization will promote efficiency in science through knowledge sharing. (more…)

Negotiating Better Mortgage Rates

Many of the best real estate investors in the world will tell you that the best real estate deals are often done during times of economic volatility. The most current recession is no exception to this rule.

Savvy real estate investors are able to negotiate much better mortgage rates for themselves in the wake of the Great Recession than they would ever have been able to do in more stable economic times. If you are looking for a home or investment property, heed the opportunity that you have with historically low interest rates and loaning institutions that are looking to quickly get rid of all of the properties on their books.

However, banks are still out to make a profit and they will not give away the information that you need to get yourself better deals. Below are a few techniques that you can use to negotiate yourself the absolute best mortgage rate that a loaning institution is willing to give. (more…)

Crisis in Academic Publishing

“In almost every country in the world, research is supported by public funds. When researchers publish their results in academic journals, they do so for free. The results are also reviewed by peers for free. And journals often require researchers to give up their rights to these articles. Then, major publishers or learned societies sell their journals at exorbitant prices to libraries… which are also financed by public funds! It’s a vicious circle in which taxpayers pay for the production and access to researchers while publishers and societies make profits of 30-45% before taxes. It’s outrageous!” exclaimed Jean-Claude Guédon. This professor of comparative literature at the Université de Montréal is far from being the only one to protest. In recent months, more than 11,000 researchers worldwide have expressed their dissatisfaction through a petition calling for a boycott of Elsevier. This academic publishing giant earned profits of more than US $1.1 billion in 2011. (more…)

Recreational Fishing Brings Salt Marsh Die-Off

As recreational fishing activity has reduced predators in many of Cape Cod’s salt marsh ecosystems, Sesarma crabs have feasted on grasses, causing dramatic die-offs of the marshes, according to a new study. The researchers assessed the “trophic cascade” in several experiments that also ruled out alternative explanations for the problem.

PROVIDENCE, R.I. [Brown University] — Recreational fishing is a major contributor to the rapid decline of important salt marshes along Cape Cod because it strips top predators such as striped bass, blue crabs, and smooth dogfish out of the ecosystem, according to new research by Brown University ecologists.
