      This is Caitlyn with the Society for Science (the group that sponsors the ISEF & RTS. I saw her give this talk in person last October. she gives some really good suggestions for reconnecting to the curiosity and wonder of your childhood. It is THIS skill that separates the typical student from the creative mind of a scientist. Will YOU try out any of her suggestions??

  • Locate a data set that interests you, see how others students have used large data sets in their research, and learn about current scientific studies fueled by big data.
  • Sean Nash on 23 Jun 23
     
    Another really solid pathway into project development is the examination and study of already existing large data sets. I have seen excellent projects that didn't even require students to generate their own data. Instead, they utilize already existing data to answer questions others may not have posed before in relation to that data set. At the very least, becoming familiar with these lines of research can help you discover a line of research that is most compelling to you!

    This is super interesting to me... both the content itself AND the fact that this is not far from feasible for an advanced HS study. Phytohormones: FASCINATING, accessible, relatively easy to apply, and the immediate question is... is it measurable? We can certainly measure the effects of applied plant hormones simply by recording the growth and development data of the plants we apply them to. What this article gets at (from a VERY brief SKIM) is the need to measure increases of hormones levels INSIDE plant tissue. Now, this is something that requires sophistication beyond what we have a BLHS. However, it might be able to be detected by NMR (nuclear magnetic resonance), HPLC (high-pressure liquid chromatography), or IR spectroscopy. If we know exactly what we're looking for in plant specimens/samples, and we ask super professionally, perhaps we could get the chem department at UMKC to help us use the right tool for the job to detect and measure these things.

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.

      These "individuals" could just as easily be plants of lower invertebrates (as model organisms at this level). This is fascinating to me. There is no doubt that we would be limited in our ability to work with ionizing radiation, but that's not to say a project couldn't be developed along these lines. I never cease to be amazed at what a motivated student can resourcefully come up with when their passion for a particular line of research is so high.

      very interesting article, there is a conclusion with insights to this underlining issue in the "read original paper" link in red. I overall think its a ear pricking issue that has yet to be solve or given the clear conclusion as to why it happens in the first place.
  • pre-flight strength: the length of this period is likely to depend on age, sex, genetic differences, and childhood exposure to pathogens.
  • These observations suggest that our immune system might be weakened by space travel.

      could it have a possible connection with the strong gravitational pull while actually going up to space? (like the continuing feeling of a steep rollercoaster drop).
  • ...1 more annotation...
  • change in gene expression of leukocytes under microgravity is triggered by ‘fluid shift’, where blood plasma is redistributed from the lower to the upper part of the body, including the lymphatic system. This causes a reduction in plasma volume by between 10% and 15% within the first few days in space. Fluid shift is known to be accompanied by large-scale physiological adaptations, apparently including altered gene expression.

  • “This is hardly surprising since most of the early [Black] pioneers of anthropology have only recently been brought to light.”

      Sadly not surprising. There are many amazing discoveries that are overlooked and even forgotten because they were performed or written by women or non-white people.
  • It did not take long for Firmin to question his membership in a group openly hostile to people who looked like him. Faced with such a tough environment, Firmin remained silent at meetings.
