      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! Once you get inside projects that you get ideas from, feel free to save them in Diigo for later, or share really interesting ones with others you think might benefit from seeing it. One final thing: you might also get some tips for elements of their presentation that appeal to you.

Mysterious Underwater Acoustic World of British Ponds Revealed in New Study | Current S... - 0 views

  • 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.

      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

      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.

      Here is the obvious value proposition if you could work this out.
  • Publication: Jack A. Greenhalgh, et al., Diel variation in insect-dominated temperate pond soundscapes and guidelines for survey design, Freshwater Biology (2023). DOI: 10.1111/fwb.14092.

Race car drivers tend to blink at the same places in each lap - 2 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
    • Sean Nash
      Sean Nash on 06 Jun 24
       
      Ok.... 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.

      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 06 Jun 24
       
      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.

Microwaving an insecticide restores its mosquito-killing power - 0 views

  • Heating an insecticide can give it new life.
    • Sean Nash
      Sean Nash on 11 Jun 24
       
      Wait... what?
  • 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.

      Seems like potential feasibility
  • The microwave worked just as well, but Kahr cautions that people shouldn’t use the same microwave for heating food and insecticides.

  • insecticide resistance is a growing problem
  • “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 11 Jun 24
       
      Another positive...
  • 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.
  • 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. We would just want to get early approval from the fair re: hazardous substances. I think we could.
  • Kahr and colleagues previously discovered that heating deltamethrin changed its crystal structure, which let it work faster

    I wonder what sort of electronics were needed to accomplish this. I also wonder how difficult it would be to attach those to a living insect without sacrificing it.
