      Wait, what? Do say more.....
  • Microwaving the insecticide deltamethrin rearranges its crystal structure but doesn’t change its chemical composition. The rearrangement renews deltamethrin’s ability to kill mosquitoes that have become resistant to the insecticide, researchers report April 21 in Malaria Journal.

  • insecticide resistance is a growing problem
  • It is encouraging that heated insecticide killed highly resistant mosquitoes, says Hemingway, who directs the Infection Innovation Consortium, a public-private effort to find new ways to combat infectious diseases. But, she says, “this is not something we can take and use that tomorrow.”

      OK.... this is how you can find an opening (not saying THIS ONE is necessarily, but, when you see language like: "we can't really do it just yet," that is a screaming opportunity to see what we MIGHT be able to add to that.
  • It’s not certain that the heat-treated deltamethrin would retain its more potent crystal structure through the net-making process.
  • Kahr’s team is working on incorporating the heat-treated crystal into nets.
  • “There are all kinds of social and cultural things that you could propose from a scientific perspective that wouldn’t be welcomed by a community of homeowners.”
    • Sean Nash
      Sean Nash on 25 May 23
       
      Again... this reads: "potential research opportunity."
  • Kahr and colleagues previously discovered that heating deltamethrin changed its crystal structure, which let it work faster

  • 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
    • Sean Nash
      Sean Nash on 25 May 23
       
      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
    • Sean Nash
      Sean Nash on 25 May 23
       
      OK, now this SCREAMS: "potential research idea."
  • Nishizono and colleagues mounted eye trackers on the helmets of three drivers and had them drive three Formula circuits
  • 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.
    • Sean Nash
      Sean Nash on 25 May 23
       
      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.
  • “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.”
  • 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.
    • Sean Nash
      Sean Nash on 25 May 23
       
      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.

  • The previously hidden and diverse underwater acoustic world in British ponds has been revealed by a team of researchers at the University of Bristol.

      So... my immediate thought is: How cool would it be to do this here? One thing we DO have: PONDS. See if this *sounds* interesting. Get it? ;)
  • Acoustic monitoring has been shown to effectively survey birds and monkeys in rainforests, and marine mammals in the oceans. However, freshwater environments have remained largely unexplored despite their diverse soundscapes.
    • Sean Nash
      Sean Nash on 04 Jun 23
       
      BOOM. Again, "relatively unexplored" is super exciting verbiage to me. Acoustics. Hydrophones. Is this feasible? Is the equipment affordable? If not, could we borrow one? Dig into it. What are the possibilities?
  • analysis of the audio files revealed clear daily acoustic activity cycles in each pond
    • Sean Nash
      Sean Nash on 04 Jun 23
       
      Aside from the exploratory surveys you would do just to see "what's out there" and assess what we CAN learn from listening to a pond, you could make it experimental by comparing ponds you've assessed the health of by other means. In other words, do acoustic comparisons between two ponds correlate with what you find by doing a macroinvertebrate sampling? I really LIKE the possibilities in this one!

  • Typically, a nocturnal chorus is made by aquatic insects that compete to attract mates by producing strange scratching sounds as they rub their genitals against their abdomens. During the daytime, however, aquatic plants dominate the underwater orchestra with rhythmic whining and ticking sounds produced as tiny oxygen bubbles are released by plants respiring in the hot sun.
  • Using this acoustic method, the presence of species, and a determination of ecological health, can be inferred simply by listening to the natural world without disturbing the environment or harming the plants and animals within it.

      This is a really good way to dive into specific categories and explore the projects that made it to this year's ISEF. What I would do is start with what immediately interests you for now... and pick up some tips. You might get ideas for areas/topics to research. You might see creative methods used in various studies. Pay particular attention to the fact that some utilize equipment only available at a university or corporate lab, but... many also feature creative methods done by students at home or in school labs as well!

Learning in Plants: Lessons from Mimosa pudica - 4 views

Mimosa learning plants botany research SCI-I science student lab potential research idea biology HSR HSR-2023

shared by Sean Nash on 23 Jun 23 - No Cached
  • there is a lack of observational data on the behavior of plants
  • Observational research allows the researcher to establish baseline activity and response levels of the subject
  • Perhaps the first study of learning in plants was a habituation experiment reported by Pfeffer (1873) using the sensitive plant Mimosa. In this experiment, repeated mechanical stimulation of leaflets led to a decrease in sensitivity
  • ...12 more annotations...
  • the question naturally arises as to whether Mimosa can discriminate between stimuli. This was answered in the affirmative by Holmes and Gruenberg (1965) whose experimental design included a drop of water and finger touch as stimuli
  • the results suggest that Mimosa can discriminate between stimuli
  • Thomas performed an experiment on classical conditioning in Mimosa that took advantage of the finding that, under field conditions, the leaflets of Mimosa slowly drop as dusk approaches and slowly rise at dawn (personal communication). In the experiment, the CS was turning on the light in the growth chamber and the US was touching selected leaflets. Thomas found that leaflets in the paired condition showed conditioning compared to a light only or alternating stimulation condition. This finding should be replicated with controls for pseudoconditioning.
  • Given the importance of the Gagliano et al. (2014) experiment and the failure to replicate some previous experimental results it is critical that the Gagliano et al. (2014) results be repeated by an independent laboratory.
  • In addition to Mimosa, habituation has been found in the carnivorous plant Drosera (sundew
  • Applewhite (1975) cites an experiment by Darwin reportedly showing habituation in the passion flower (Passiflora gracilis). During this experiment, when Darwin mechanically stimulated the passion flower tendrils, the tendrils no longer responded after 54 h of training.
  • Abramson et al. (2002) investigated the use of bioelectrical potentials as a method to explore plant behavior.
  • In an interesting article, Karpinski and Szechynska-Hebda (2010) discuss the intellect of plants from memory to intelligence. By studying recall, the researcher investigates a host of independent variables and that are solidly anchored to a set of dependent variables. This study focused on recall at the cellular level rather than as an externally observable behavior. The discussion of plant learning at various levels, from cellular to organismal and from different scientific fields is exactly what is advocated for in this article
  • There is also interest from behavioral scientists seeking to determine whether the similarities and differences in learning found among invertebrates and vertebrates could also be found in plants (Warden et al., 1940; Applewhite, 1975; Abramson et al., 2002; Guiguet, 2013).
  • The majority of early plant studies used the Sensitive plant (M. pudica). Mimosa has much to recommend it for learning studies. They are easy to maintain, much is known about its natural history, and they have a visible leaf closure response to external stimuli. However, there are drawbacks in the use of Mimosa, for example, it takes about 15 min for a leaf to recover (Holmes and Gruenberg, 1965) and not much is known about its genome in contrast to model species such as Arabidopsis thaliana whose entire genome is known.
  • In the following section we will focus on methods to develop studies utilizing habituation, sensitization, and classical conditioning techniques. Instrumental and operant conditioning will not be covered because at this time there are no Mimosa studies in these areas; although one can envision a situation where the opening and closing of a leaf can be detected electronically. Once detected, the response would produce a consequence such as an airpuff or changes in light intensity.

      This well-compiled article does a really nice job of outlining the history of study regarding plant behavior. It also suggests model organisms for study. Mimosa is a favorite of mine as their response is VERY rapid and quite visible for a plant! There are all sorts of feasible project ideas that could arise from this area of research.

    I think a possible research idea could be redesigning NICU incubators to allow for less electromagnet interference with the babies with the use of grounding.
  • Sean Nash on 07 Jun 23
     
    Interesting, for sure. Two things... the actual measurements they made on children (skin tests, etc.) are a no-go for us. I'm not sure what our model system could be for checking the electrical outputs of whatever design changes were made. We would need to know a lot more about the current setup in NICUs. There is no doubt a lot of design in how things are currently set up. Essentially: why things are set up the way they are right now? You would have to know every variable currently considered, and then look for spots where simple changes can be made. Second thing: go back to the ISEF categories in Engineering and check out how those projects look at the national level. Just go get a feel. Engineering is a bit different from typical "hypothesis testing" seen in most natural sciences. Very cool, but different. Give it a look.
