The phrase, “beauty is in the eye of the beholder” seems especially true for scientists. What we study becomes not only intellectually beautiful, but also literally beautiful: the form is pleasing to the eyes. Appreciation and endearment develops over time as scientists gaze on their subject for hours, days, years. In fact, research by the psychologist Robert Zajonc shows that the more familiar you are with something, the more likely you are to enjoy it.
These beautiful little creatures are incredibly skilled at sniffing out mates. The pheromone the females release is called bombykol. Scientists are on the hunt for exactly how this pheromone activates the male brain.
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.
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
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
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
