The platypus and the echidna are the only mammals that have the power of electroreception, which means they can sense electrical changes. Check out this new Weird Animal Brain to learn how the platypus uses its bill to catch prey underwater!
Epigenetics change which genes are active and which are inactive. Research over the past few years has shown that these changes are important for protecting the brain from neurodegeneration and injury. A review paper came out on May 18th in the journal Nature Reviews Neuroscience that summarizes this research. Check out the infographic for a description of the review paper.
The brain is one of the most complex and amazing structures in the universe. It allows us to experience the world, feel, remember, and plan for the future. But for at least one organism, the brain is only a means to an end. Learn more in the infographic below!
It’s easy to find information on the internet — especially information that confirms what you already believe to be true. Through search engine bias, your Facebook newsfeed bubble, and confirmation bias, we can unknowingly surround ourselves with a cozy blanket of comforting information. Whether or not this information is true, however, is a different story. Check out this infographic for some strategies for how to know if what you’re reading is true.Continue reading
Sometimes it’s hard to understand why scientists do what they do. Why spend a career studying cells, fungus, or flies? Other than being nerdy and wanting to learn about our world, what’s the point?Continue reading
The octopus almost reaches alien status when it comes to its brain and nervous system. And yet, the differences can help us understand more about the human brain as well as unique solutions nature has come up with for difficult problems like camouflage. Octopuses can see polarized light, but cannot see color. However, their skin changes both color and texture to camouflage with the surroundings.Continue reading
Last month, on the big island of Hawaii, I swam with giant, beautiful aliens. Or at least that’s what it felt like. I went night snorkeling with manta rays and had the privilege of seeing 10 or 11 graceful behemoths. Some had a wingspan of over 10 feet long. Before our group got in the water, to prepare us for what we were about to see, our guide reassured us that manta rays are like sharks, but only the good parts, none of the scary parts. They don’t have teeth, they only eat plankton, and they have no stinger like their sting ray counterparts.Continue reading
Everyone knows sharks are fierce predators. How exactly they hunt so well is in part due to their extra sixth sense: electroreception!Continue reading
Marine mammals, such as dolphins, whales, and porpoises, spend their entire lives at sea. Like us, they need to breathe, avoid danger, and care for their young. Like us, they need to sleep, which — for us — involves almost total unconsciousness and paralysis. So how do these marine mammals not drown when they sleep?Continue reading
The jewel wasp’s venom is potent on two levels. Continue reading
Have you ever wondered if you experience the world like everyone else? We assume that our senses tell us what’s going on in the world, but they’re far from perfect. Synesthesia is a cool example of when our senses have a mind of their own.Continue reading
We have someone new joining our team! She is a neuroscience PhD student at the University of Iowa, and she studies speech perception – but let’s let the animation she created explain exactly what that means:Continue reading
