Sharks use ESP

As the water warms in summer, beachgoers flock to the ocean and thoughts of “jaws” inevitably surface. A shark’s ability to home in on the scent of blood is legendary, but many people are surprised to learn that sharks have a stealthy sixth sense to find prey and explore the world around them. Sharks have the ability to sense an electric aura that surrounds all creatures in seawater–including people. Continue reading

Why do nervous systems use slow voltage changes rather than fast electric currents along wires?

Richard Dawkins used his Twitter account to ask some unanswered questions about biology that he finds fascinating, inviting others to share ideas about hypothetical life forms that may or may not have evolved. By nature, these questions can only be addressed using some degree of speculation, but I find this one particularly interesting and I will attempt to answer it. He asks: Continue reading

NEURO.tv Episode 11 – Moral decision-making and the brain, with Joshua Greene.

What experiments do psychologists use to identify the brain areas involved in moral decision-making? Do moral truths exist? We discuss with Joshua D. Greene, Professor of Psychology at Harvard University and author of Moral Tribes. Continue reading

Scientists on Twitter.

Neil Hall from the University of Liverpool has published a very interesting mini-study on scientists and Twitter. He developed a metric that compares the popularity of scientists on Twitter to the impact of their publications within peer-reviewed journals. The metric is called the Kardashian Index, a reference to the fact that Kim Kardashian became wildly popular for no apparent reason, and a wink at those scientists who get Twitter popularity without having accomplished as much as others in their scientific career. Neil Hall is not necessarily critiquing the individuals who use Twitter to their advantage – he simply creates a metric that finds discrepancies between Twitter popularity and scientific popularity. The idea is brilliant, but in my view the short article is based on an incorrect premise. The premise is that science and social media contributions are two fundamentally separate things that can be compared to each other. Continue reading

A picture of four spiny lobster taken off of the Florida Coast. -- Douglas Whitaker

The rhythm of lobster season

Today is the second and last day of “mini-season” here in South Florida. That is, the last Wednesday and Thursday of July where Florida lobsters are available for the taking by non-commercial lobster hunters. I grew up in New England and I love me some huge (i.e. 2-3 lb) Maine lobsters, but since establishing some roots down here in sunny Florida, I’ve grown to like the smaller, but still sweet tasting cockroaches of the sea.

Book Review: Consciousness and the Brain

Every ten years the scientific study of consciousness passes a milestone. A decade ago the milestone was the publication of Chrisof Koch’s book “Quest for Consciousness” (2004). “Quest” established the groundwork for a scientific approach to the study of consciousness and described progress using techniques of neuroscience and experimental psychology1.  Stenislas Dehaene’s book “Consciousness and the Brain: Deciphering how the Brain Codes our Thoughts” presents a mass of new data and along with new theory. I believe it is a major consolidation; a milestone marking the trail forward for the next decade.  Continue reading

Lucy and the 10 Percent Brain Myth

It’s unfair to have Morgan Freeman, with his smooth, deep voice, say it. In the trailer for the upcoming film Lucy, the actor who has played both the President and God addresses an auditorium of students and says, “It is estimated most human beings only use 10 percent of their brain’s capacity…Imagine if we could access 100 percent.” It’s hard not to believe Morgan Freeman. But in this case, he’s wrong. Continue reading
