Caperea alive!

by Darren Naish in Tetrapod Zoology





By now you might be relatively familiar with the bizarre soft tissue and bony anatomy of the peculiar, poorly known Pygmy right whale Caperea marginata [a juvenile Caperea that stranded on New Zealand is shown above; original image by New Zealand Department of Conservation, from Te Papa's Blog]. If you missed the relevant articles you might want to check them out here (on the giant, asymmetrical laryngeal pouch), here (on the vertebrae and ribs) and here (on the skull, ribs and tail). These ........ Read more »

Ocean acidification negatively affects coral establishment

by Phil Camill in Global Change: Intersection of Nature and Culture


When CO2 from fossil fuels accumulates in the atmosphere, some of it dissolves into the oceans where it reacts with water to form a weak acid (H2CO3) —carbonic acid— that lowers seawater pH and makes it increasingly difficult for corals and other calcitic organisms to form their calcium carbonate (CaCO3) skeletons.
A new study in the [...]... Read more »

Potential genetic basis for why BPA is harmful to animals

by Phil Camill in Global Change: Intersection of Nature and Culture


In a forthcoming article in Proceedings of the National Academy of Sciences, Patric Allard and Monica Colaiácovo use a nemotode (round worm) system to explore how BPA damages genetic processes in animals.
BPA ranks among the highest production volume chemicals with a global annual production scale of ≈4 million metric tons. It is commonly used in [...]... Read more »

John Everett, part III.0: If some is good, then more must be better.

by csoeder in Topologic Oceans

Have you ever gone camping with someone who doesn’t know how to build a fire? It might go something like this: you get a pile of twigs burning, and immediately your friend starts piling on huge logs. The fire dwindles. “Hey,” your friend says, “This fire sucks. It must need more logs.” If some fuel [...]... Read more »

Lions and lollipops. The brain’s amazing race for meaning.

Some take the tube, others the train…The Amazing Race in the brain It makes sense that we need to process and respond to some stuff we see quicker than other stuff we see.  Take for instance a lion versus a lollipop.  This paper by Pessoa and Adolphs explores the mechanisms behind emotional processing of visual [...]...

Education of Children as a Form of Manipulation

by Colin Schultz in CMBR

This is another in a series of essays that I’m not *so* embarrassed by that I felt like sharing. Eric Cave in “What’s Wrong with Motive Manipulation” described a variety of ways in which we could be manipulated to alter our behaviour, movement or actions. He accurately described two different broad sets of motives which are acted [...]... Read more »

Autism-Related Gene Spotlight: SLC4A10

by Lindsay in Autist's Corner

I'm doing a series describing genes that have been found to be associated (even weakly, as this one is) with autism. This one is a membrane-spanning transport protein that exchanges sodium and bicarbonate ions for chloride ion; it is primarily expressed in the central nervous system. Mutations in this gene lead to changes in neuronal excitability, which can manifest as seizures.... Read more »

Transparent mouse embryos and hematopoietic cell clusters

by Erin Campbell in the Node

I was lucky in graduate school and my postdoctoral research—I was a microscopist working on a transparent organism (C. elegans).  Some microscopists don’t have that luxury, but have developed amazing techniques in order to visualize development in organisms such as mice.  In the November 1 issue of Development, Yokomizo and Dzierzak use a technique that [...]...

Antibiotics and gut bacteria

by Lab Rat in Lab Rat

All microbiologists end up writing about gut bacteria at some point. It is the way of things. Disease of the Week is currently doing a whole series on it, and a few weeks ago I covered the interaction of the immune system with gut bacteria (here). However a recent paper came out in Microbiology Today concerning the affect of antibiotics on gut bacteria, which is a topic that I both find interesting and have had some actual experience with.I've taken antibiotics a few times, and each time I've fo........

Fattening Up Microbial Geological Biomarkers

by Paula Welander in Small Things Considered

by Paula Welander

First Evolved! Last Extinct! This prokaryotic pride motto was coined by my undergraduate advisor (and good friend) Prof. Mark Martin. As a microbiologist, I love this motto for many reasons, but especially because it alludes to one of the underlying principles of my current research. Microbes were indeed the first to evolve and the metabolic inventions of ancient microbes greatly influenced the ancient Earth’s environment and the evolution of life. The interaction between ........ Read more »

The Reality of Health Care Rationing

by Rob Mitchum in ScienceLife

Tuesday’s midterm election results appeared to deliver a strong message of discontent to the young Obama administration. With Republicans gaining control of the House of Representatives and closing the gap in the Senate, many analysts saw the election as a rebuke of the Democratic agenda of the last two years. Perhaps the highest-profile of those [...]... Read more »

Humor in Scientific Publications

A couple of years ago, two researchers at the Technion tested whether or not funnier scientific article titles yielded higher citations. Their article, Amusing titles in scientific journals and article citation, takes the titles of over 1000 articles and has them rated on two scales, pleasantness and how amusing they are. They then checked to [...]... Read more »

Improvement of Memory in Alzheimer’s Patients Through Music

by Psychology 379 bloggers in Cognition & the Arts

According to the United States Alzheimer’s Association, over 5.3 million people in the US are currently suffering from Alzheimer’s disease. Alzheimer’s is a chronic and progressive form of dementia in which symptoms begin as mild memory impairment and progress into loss of conversational ability, motor function, speech, and the ability to eat. As shown in the illustration below, the disease “eats” neurons in the brain, causing the symptoms discussed above.... Read more »

Their evidence suggested that FRH played an important role in ... Read more »

Fan Identity and Team Choice

by Krystal D'Costa in Anthropology in Practice

How does one become a fan? Choose an allegiance? Decide that you’re going to wear bright green, or purple and gold, or paint your face orange and black? In many cases, these allegiances are decided for us—handed down via familial loyalties or decided by geographic boundaries. I raised this question on Twitter a few weeks ago, and the results all indicated that team alliance is linked to one’s point-of-entry into fandom: if you begin watching Team A and learning about the sport via Team A,........

For some, planting a tree is an act of love. In many parts of the world, however, tree planting has become a source of often violent conflict. The rapid expansion of industrial plantations for wood, palm oil and rubber is sparking protest around the globe, a new analysis finds. The unrest suggests that pro-plantation policies […] Read More »... Read more »
