Read an interview with UM senior Ahmed Suhaib that appeared in today’s issue of the Michigan Daily discussing Backyard Brain’s collaboration with the Biomedical Engineering Design Program to help design our RoboRoach.
Stay tuned, as we work to bring you this and other exciting products in the near future!
Are you a fan of DIY neuroscience or science in general? If yes, you’re bound to enjoy the long-awaited episode of the world-famous Youtuber Vsauce’s series “Mind Field” featuring some of our staple experiments!
Until recently, the show used to require a Youtube Premium subscription, but now you can enjoy all three seasons for free.
So what’s all the fuss about?
If you’re new to the “Mind Field” show, you’re in for loads of fun and tons of knowledge. Vsauce is a celebrity educator who took it upon himself to explain complex scientific notions in a dynamic and interesting manner, with a tinge of weird and quirky scientific humor. Kind of what we are doing here at Backyard Brains! So it only makes sense that our co-founder Tim Marzullo was a perfect addition to the show. (Check out this blog post to see how much fun he had while shooting the episode.)
The episode titled “The Electric Brain” demonstrates another instance of superb cockroach surgery followed by a bug race! You can see our RoboRoach in action as it hijacks a cockroach’s nervous system to send electrical impulses to their antennae. Tim, Michal and Alie controlled the bugs via their smartphones by, you’ve guessed right, swiping left and right.
It goes on to confirm that swiping got a whole new cultural meaning with the RoboRoach gizmo. (Just remember not to use that hack on Tinder!)
Apart from our own nerdy contribution, the episode is full to the brim of bizarre and even macabre details from the history of neuroscience that will make you totally fall in love with the field – that is, if you haven’t already.
The video also demonstrates how humans can control other humans by turning them into a real puppet show. It makes for a perfect prank that you can perform on your friends.

Kafka couldn’t have imagined it better. Two specimens of the cockroach phylum were going about their business in a Myanmar cave about 99 million years ago. One day they got trapped in tree resin, which then turned to amber and preserved their little bodies to this day to tell us an impressive tale of time, life, death, and metamorphosis.
Both belonged to the Nocticolidae family, which comprises a couple dozen cockroach species inhabiting caves and caverns. Our small but hardy hairy-legged friends probably even managed to survive the mass extinction event that killed off the dinosaurs along with three-quarters of all life on the planet. The researchers, who recently published their findings in Gondwana Research, labeled the two fellas “the only known dinosaur age cave survivors”. It goes to show that cave roaches are far older than we used to think. Before this discovery, it was commonly held that they date back to 65 million years ago (the Cenozoic era).
From now on, we should know better than to underestimate them.
Let’s Get to Know Them Better!
The two species now carry the names of Mulleriblattina bowangi and Crenocticola svadba. While being pretty similar to each other, the Mulleriblattina seems to have been confined to the cave life, whereas Crenocticola was a bit more curious and probably ventured outside the cave.
The planet was not a friendly place back in the Mesozoic era. But our roaches didn’t seem to mind. Resilient as they were, they developed adequate traits that would allow them to thrive in damp and dark cave environments where no other creatures are known to have existed back then. Their very long antennae allowed them to better explore their gloomy surroundings, where eyes were almost useless. The wings got stunted since they no longer needed them. The insects weren’t brown or black like their modern-day domestic relatives, but yellowish or even transparent. What use is color anyway in a place that never gets any light?
What’s even more amazing is that all of those features make the Mulleriblattina look strikingly similar to its modern cave relatives. Some things never change, and neither does the roaches’ penchant for darkness.
Scary or Not So Scary?
By this point, you’re probably beginning to wonder about their size. No reason to shiver on that account! They were actually very small – just under 5 mm (roughly 1/4in). That wouldn’t make you cringe to the depths of your soul now, would it?
The length of their limbs probably would though. Especially the cerci (a pair of appendages protruding from underneath the bug’s rear end), which were significantly longer than in your average domestic roach.
But what did they eat? While the dinosaurs were still there, these two beauties may have feasted on their droppings that they would have found near the cave entrances. Once the gigantic reptiles went extinct, they probably made do with bats’ poop. How’s that for adaptability? The scientists even spotted some particles of undigested food in their lower abdomen. Ew!
There’s another mystery the researchers had to face. How did the tree resin make it into the cave to form amber? There is no exact answer. It probably poured down through cracks and crevices on the cave’s roof. Nature sure is resourceful while taking its course.
Let’s Get Serious for a Moment… Could We Operate on These Ancient Bugs?
You guessed right – this beautiful story about ancient roaches trapped in amber is particularly exciting for us roach-loving nerds at Backyard Brains. As you may or may not know, we’ve been harboring a lifelong appreciation and even love for roaches of all shapes, sizes, and ages.
So it’s only natural that our first thought after reading the Gondwana Research paper was whether a Mulleriblatina or a Crenocticola could possibly carry a RoboRoach backpack. Alas, both were small and, frankly, too fragile for so heavy a burden. (Okay, maybe we could build a peewee backpack for them to sport). Our next concern was: if they lived here and now, would they readily lend themselves to one of our experiments? We weren’t happy with the answer. Their legs would have been too short and slender for us to operate on.
In fact, the longer cerci might even provide for new opportunities to record and stimulate the nervous system of the cockroach in interesting ways! Researchers have already used our SpikerBox kits to record from the cerci, and we even had a summer research fellow pursue a research project for a version of the RoboRoach which could control EVERY direction the roach moves by stimulating both the antenna and cerci.
The third thought was a sensible husbandry dilemma: would they want to even taste some of our lettuce or carrots for that buffet-style dinner? (It’s tough to get ahold of an ounce or two of dinosaur guano these days.) That one went unresolved.
Do They Resemble Our Domestic Roach?
After all, we have to acknowledge both the similarities and differences between, say, your average Periplaneta americana (American Cockroach) and these two antediluvian beauties. All roaches are fond of gloom, and all of them are apt survivors. There’s hardly such thing as picky eating among this crowd! Those are traces of their common, eons-old ancestry. It dates back 300 million years ago, to the time before the ancient supercontinent Gondwana broke up to huge chunks of land now known as Antarctica, Africa, South America, Australia, India.
But they are also mutually different. The American roach is your regular cohabitant that you may notice as it forages through your dimly lit basement. Even though it likes darkness, it will still tolerate some traces of light – that’s how much it loves your bread crumbs or even your dandruff! And luckily for our experiments that include bug leg surgery, it boasts a giant size compared to its distant relatives Mulleriblattina and Crenocticola. Its 1.6 inches of length is just enough to scare the wits out of you as it scuttles across your dinner table. It’s also known to be a genius in the evenings and a moron in the mornings. (Which makes us think that our cave-dwelling roaches must have been Einsteins!)
So next time you reach for your phone to dial pest control, think twice. Maybe it would be more ethical to let those little guys carry on with their lives. Some of them might even make it into history books one day.
