    This is a crowd-sourced document I created for a session with high school research teachers in Washington D.C. in 2022. SAVE this document and use it to explore some of the more commonly-used model organisms for all sorts of biological research. There is a TON to explore here!

Race car drivers tend to blink at the same places in each lap - 0 views

  • The world goes dark for about one-fifth of a second every time you blink, a fraction of an instant that’s hardly noticeable to most people. But for a Formula One race car driver traveling up to 354 kilometers per hour, that one-fifth means almost 20 meters of lost vision
  • People are often thought to blink at random intervals, but researchers found that wasn’t the case for three Formula drivers.
  • the drivers tended to blink at the same parts of the course during each lap, cognitive neuroscientist Ryota Nishizono and colleagues report in the May 19 iScience

      Interesting. So, do we do the same thing while driving around town? Could you design a method to record eye blinks as people drive known routes around town? We could simultaneously use the Arduino Science Journal app on the iPhone to also correlate physical data in a moving car like acceleration/deceleration, motion in X, Y, Z directions, etc. I wonder if we could find a correlation in everyday driving that could help from a safety perspective?

  • He was surprised to find almost no literature on blinking behavior in active humans even though under extreme conditions like motor racing or cycling

      Ok.... this screams "potential research idea."
  • “We think of blinking as this nothing behavior,” he says, “but it’s not just wiping the eyes. Blinking is a part of our visual system.”
  • Where the drivers blinked was surprisingly predictable, the team found. The drivers had a shared pattern of blinking that had a strong connection with acceleration, such that drivers tended not to blink while changing speed or direction — like while on a curve in the track — but did blink while on relatively safer straightaways.

      What sort of implications does this have for driving in key, known, busy interchanges in KC? Could we potentially provide data to show certain stretches of highway need more signage, etc? That could have civil engineering implications.
  • Nishizono and colleagues mounted eye trackers on the helmets of three drivers and had them drive three Formula circuits
  • Nishizono next wants to explore what processes in the brain allow or inhibit blinking in a given moment, he says, and is also interested in how blinking behavior varies among the general population.

      While the "brain" part might move beyond our feasibility, the potential of finding real correlations to driving patterns or routes is a completely different spin-off and one that could have really practical suggestive applications for city planners, etc.

    Interesting. The video clips are especially valuable for understanding their methods. So, these tests have been done... but what other sorts of learning tests might be possible? Are there any that might even show value in this species beyond just "what is possible for the bee nervous system to accomplish?"

  • He adds that he doubts that the findings are applicable to other insect species, which still might act purely on instinct.
  • Invertebrate nervous systems, physiology, and sensory experiences are dissimilar to ours, and designing experiments to measure their emotions has been challenging. 
  • If the responses weren’t purely reflexive, it would open up the possibility that the animals could feel pain. 
  • ...1 more annotation...
  • After placing acetic acid—a mild irritant—on the crabs’ antennae, they found that the crabs rubbed their antennae against the glass of their aquarium, seemingly in an attempt to take the acid off.

      The use of an invisible irritant rather than a notable injury shows that they can feel the pain, instead of just noticing an injury to their body.

  • Called gravimeters, such devices can detect tectonic plates shifting, sense the movement of underground water, reveal hidden oil and gas reserves, and track magma within volcanoes to provide data for predicting eruptions, along with many other applications.

      How is a Gravimeter able to detect the movement of tectonic plates shifting, does it detect sound waves or vibrations?

  • Rho's work is grounded in a social science framework called Fuzzy Trace Theory that was pioneered by Valerie Reyna, a Cornell University professor of psychology and a collaborator on this Virginia Tech project. Reyna has shown that individuals learn and recall information better when it is expressed in a cause and effect relationship, and not just as rote information. This holds true even if the information is inaccurate or the implied connection is weak. Reyna calls this cause-and-effect construction a "gist."

      Fuzzy Trace Theory looks interesting for this, and perhaps many other reasons. I want to learn more about this myself, and I'm wondering if this theory could be put to work in other potential behavioral science projects. What do you think?

  • The experts selected onion plants to test out this idea, known for their high sensitivity to toxins in the environment. In beakers of water containing bentazone, they grew onion root tissue, called meristems, measuring its cell division and root growth as a sign of health.

      One of the things I want VERY badly for our program... is a set of equipment for histology... where we can take things like onion root tips and lock samples in wax, slice them incredibly thin (microslices), and then be able to mount them onto slides for analysis.
