The Brain Scoop: An Electric Eel, and a Caiman

by thebrainscoop:

Ten minutes at our first camp and someone casually mentions to me that there was a 1.5 meter-long electric eel hanging out in our bathing pool, so, y’know, just watch out.

That wouldn’t be the last time I’d see one, either – our ichthyologists invited us to join them for a day casting and sweeping nets through deep, black waters to figure out what was inhabiting the fresh waterways near our campsites. Freshwater fish contribute to a significant percentage of the rich biodiversity of the Amazon, but often don’t come to the front of people’s minds as quickly as birds and amphibians when thinking of rainforest animals. In fact, it’s estimated there are more than 5,600 species of neotropical freshwater fishes and they comprise perhaps 10% of all known vertebrate species.* The distribution of these fish can lend innumerable insights to how they navigate rivers and streams in the rainy and dry seasons, and how predators – like the eel – can survive. 

Check out our other videos from our journey into the Amazon!

Gender and Language Processing – Linguistics Topic 32

by thelingspace:

How do we deal with gender when we process language? Do we take it into consideration when we hear words and sentences? In this week’s episode, we talk about gender and language processing: the different kinds of gender in language, how gender influences our ability to retrieve words from our mental dictionaries, and how our views on gender temporarily keep us from considering otherwise legitimate interpretations of sentences.

This was a topic we’d wanted to address for a while, and we’re looking forward to hearing what you have to say!

The two papers we discussed:
– The word pair paper: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2686231/
– The full sentence paper: http://link.springer.com/article/10.3758/BF03211283

Hydraulic fracturing: Using scientific methods to evaluate trade-offs – Science Nation

In Colorado, drilling for oil and natural gas using hydraulic fracturing, sometimes referred to as fracking, is big business. But, questions about its impact on the air and water are far from settled.

With support from the National Science Foundation (NSF), University of Colorado environmental engineer Joseph Ryan heads a team gathering data on the pros and cons of oil and natural gas development, including the use of hydraulic fracturing. The broad research goals of the team include exploring potential impacts on water and air quality, human health and energy sustainability. For example, the researchers are investigating how long hydraulic fracturing chemicals persist should the chemicals make their way into the groundwater. And, team members are working with local residents to gather air quality data on carbon dioxide, carbon monoxide, volatile organic compounds, ozone and nitrogen dioxide.

A mobile laboratory is used to record levels of methane gas, a greenhouse gas that can come from a variety of sources including oil and natural gas extraction. The team is also looking at the benefits of oil and natural gas development so regulators, policymakers and the general public can see the complete picture before forming opinions or making decisions. The outreach and education components of the research will focus on citizen science, public involvement, and awareness of the science and policy issues.
