Should you trust that article you’re reading?

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

It’s Brain Awareness Week!

Every March, Brain Awareness Week (BAW, for short) unifies the world in celebration of the brain and mind! In order to raise awareness about how the brain works, what neuroscientists do, and how amazing new research is, scientists present interactive activities, host laboratory tours, and speak to audiences about brain-related topics.

This year, we put together a list of our favorite Knowing Neurons content that highlight how amazing the brain is! Check them out and share the awesomeness!Continue reading

What Happens If You Stick Your Head in a Particle Accelerator?

What would happen if you stuck your body inside a particle accelerator? The scenario seems like the start of a bad Marvel comic, but it happens to shed light on our intuitions about radiation, the vulnerability of the human body, and the very nature of matter. Particle accelerators allow physicists to study subatomic particles by speeding them up in powerful magnetic fields and then tracing the interactions that result from collisions. By delving into the mysteries of the Universe, colliders have entered the Zeitgeist and tapped the wonders and fears of our age.Continue reading

Why Mosquitoes Love Us

From that evil itch on your arm to torturous diseases such as malaria, Zika, dengue, and yellow fever, mosquito bites can have unpleasant consequences. But have you ever wondered why those skin-diving insects are so good at detecting humans? Not so surprisingly, the answer lies in neuroscience — in a special field called chemosensation, the sensing of chemical stimuli.Continue reading

Weird Animal Brain: Octopus

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

Stimulating Neural Circuits with Magnetism

Brain stimulation might sound like some Frankensteinian demonstration from a Victorian science fair. But in reality, it is a contemporary technique making a huge impact in neuroscience by addressing a longstanding limitation of traditional methods for investigating human brain function. Such techniques, like EEG and fMRI, can only be used to infer the effects of a stimulus or task on brain activity, and not vice versa. For example, a scientist might use EEG to study the effect of a task like arm movement on brain activity, but how can one study the effect of brain activity on arm movement?Continue reading

Weird Animal Brain: Manta Ray

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
