4:46 PM | As a butterfly flaps its wings in Tokyo, a neuron in your head veers slightly heavenward…
When you look at the edge of a table, there is a neuron in your head that goes from silence to pop pop pop. As you extend your arm, a nerve commanding the muscle does the same thing. Your retina has neurons whose firing rate goes up or down depending on whether it detects a light spot […]

Ok, this is pretty tangential, but I just have to share. One component of this blog that is hidden to everyone but me is the abundance of spam comments that show up in my queue, waiting to be approved or … Continue reading →

4:14 PM | Vaccine halves dengue cases
[Another version of this article was first published on SciDev.Net. Click here for link.]   A vaccine that can half the number of dengue cases will soon be available. A recent trial conducted in Southeast Asia shows that this dengue vaccine achieves a vaccine efficacy of 56.5%: the vaccine reduces an individual’s chance of getting […]

1:59 PM | Extreme to Exceptional Drought Now Covers Over 80 Percent of California
It’s no longer a question of 100% drought coverage for the stricken state of California. That barrier was crossed months ago. Today, it’s how severe that drought coverage has become. And in a state… Source: robertscribbler.wordpress.com Excellent article.Filed under: Climate … Continue reading →

12:17 PM | The Rise of CHARLANTA
Very occasionally, the opportunity arises for a group of people to decide where and how to build a city. In 1792 the legislators of North Carolina confronted such a moment. It had been decided that a new state capital was going to be built and that that state capital should ideally be far from the sea. Without having to worry about the best beachfront property, the legislators found themselves free to prioritize other things. So it was that they decided upon the rule to be used in placing a […]

12:00 PM | Readers Write In: What are these Frog-eating, Cottonmouth-looking Snakes?
1) This is the snake (on right) that started my whole concern (a five-footer that was in our yard). I've been told it was a black ratsnake. Is it?... My snake-obsessed little boy spotted a snake (second picture) on our evening walk tonight. We know it's not a copperhead or black rat snake or king snake—do you know what kind it is? It was thin and about 20 inches long. You would have been proud

What are the greatest neglected classics in ecology and evolution? Truly great papers or books that deserve to be much more widely known than they are?* Part of the challenge here is deciding how little-known a paper has to be … Continue reading →

12:45 AM | El Nino Project (Part 6)
guest post by Steven Wenner Hi, I’m Steve Wenner. I’m an industrial statistician with over 40 years of experience in a wide range applications (quality, reliability, product development, consumer research, biostatistics); but, somehow, time series only rarely crossed my path. Currently I’m working for a large consumer products company. My undergraduate degree is in physics, […]

9:34 PM | Researchers develop innovative way to detect fake malaria drugs that could save lives, deter counterfeiting
It looks like a simple piece of paper and it’s nearly as cheap, ideally costing just pennies. But despite its small size, it’s poised to make an enormous impact and potentially save thousands of lives.

4:22 PM | Climate Model Shows Australia’s Rainfall Decline Due To Human-Caused Climate Change
Simulating natural and human-caused climate drivers, scientists showed that the decline in rainfall is primarily a response to human-caused increases in greenhouse gases as well as a thinning of the ozone caused by human-caused aerosol emissions. Continue reading →

3:51 PM | What should we be allowed to forget?
Should we be dampening the emotional aspect of memory? Two decades ago, scientists began to wonder if they could weaken traumatic memories by suppressing the hormonal rush that accompanies their formation. They turned to propranolol, which was already on the market as a treatment for hypertension and blocks the activity of hormones like epinephrine and norepinephrine….Next, […]

3:01 PM | Things I Forget: Push/Pull Greyed out in RStudio?!?
So, on more than one occasion I have set up a repository locally, then on GitHub and pushed to that repo from the shell. This works great, but this would always result in the Push and Pull buttons in RStudio getting greyed out. I could push just fine from the shell, but not from the […]

12:30 PM | Insects Headline Art of Science Exhibit
Science is boring. Art is Stupid. Prove us wrong. These are the words that launched the annual Art of Science exhibition at Princeton University. The exhibit highlights examples of accidental art – images and video collected in the process of doing science that somehow go beyond the numeric values of their pixels. This year I was excited to have four of my photographs included in the exhibit. Taking photos while doing research gives students and scientists a chance to embrace their […]

6:57 PM | Students Discover: The third week
Time flies when you’re having fun (and working hard)! Last week marked the third and final week of our time with the Students Discover Kenan Fellows at the North Carolina Museum of Natural Sciences. The week was jam-packed with lab work, lesson planning, more small mammal trapping, visits behind-the-scenes to the Museum’s collections and Arthropod Zoo, and a special lunch with Dr. Emlyn Koster, the Museum’s director. Here are some highlights from his remarks to the group: […]

I think therefore I am; or rather, I am currently thinking, therefore I currently am. But where does the “I” come from? Much has been made of clinical cases where the self seems to malfunction spectacularly: like Cotard syndrome, whose victims believe they do not exist, even though they admit to having a life history; or […]

There is a lot of discussion on the internet about highly skewed speaker lists at symposia and conferences. For the past year, I’ve been co-organizing a small conference (~110 people) with Michael Angilletta where we’ve been practicing some of the approaches I developed and blogged about earlier for organizing a seminar series. However, in ecology […]
