The first thing I do when I get home from work each day is make a beeline for my cat Callie. As I hold her against my shoulder while she nuzzles my neck and purrs to greet me, I am overwhelmed with the urge to squeeze her so tightly that she pops like a baloon. […]

How model organisms are chosen
posted by Ricardo Lozoya
Intro Mice, fruit flies, worms, and monkeys. These are just some of the many animal species that are commonly used by scientists to learn about the nervous system, often with the goal of uncovering something about the human nervous system. If that’s the case, then the species being used is said to be a model […]
Axolotls: First Ones to the Fountain of Youth
posted by Ricardo Lozoya
Introduction If you look at today’s $50 Mexican peso (left), you won’t see the image of a past president or monument. Instead, you’ll see a lone salamander with outstretched arms and gills in the middle of a lake. For centuries, this small creature, known as the axolotl (ax-oh-lot-al), was well known to the people that […]
Genetics of Sasquatch: making cryptozoology scientific?
posted by JC Gorman
Growing up in Oregon meant I spent lots of time hearing about Sasquatch. Now working in a lab studying monkeys, I’ve spent a lot of time thinking about how different primates are related. While it is undeniable that little evidence has been found to prove Bigfoot roams the wild forests of the Pacific Northwest, perhaps […]

This myth surrounding sleep as a […]

posted by Nicole Mlynaryk
The human brain has been shaped over hundreds of thousands of years, with evolution selecting for traits that helped our species survive and thrive. So why do we still have so many genes that make us struggle? Why did our remarkable cognitive capacity come with such a susceptibility to disorder?
The Platypus: Sensing the Body Electric
posted by Catie Profaci
Patti was one of my favorite Beanie Babies. Her bright magenta body and yellow webbed feet exuded a certain sunny optimism, and her strange resemblance to a flattened duck endowed her with an undeniable silliness. I remember feeling a bit confused as to whether she was a real creature or more akin to Mystic the […]
Stop, You’re Making Me Blush

I want to take you back to the most embarrassing moment of your life. Come on, you know what that was. For some people it was giving a presentation in front of a large audience. For some it involved saying or doing something really stupid, perhaps in front of someone you were attracted to; it […]
Machines Comparing Circuitry (or, Understanding Our Uniquely Human Brain)
posted by megkirch
I became fascinated by the brain because I was – and continue to be – fascinated by humans. Why are we so obsessed with other people’s lives, including (sometimes especially) those whom we’ve never met? How are we able to communicate such complex emotions with a raise of an eyebrow or even just a glance? […]
