Hearing is be-leafing: Students invent quieter leaf blower | Hub - 1 views

    OK- so THIS specific thing is done. I have not seen the data (decibels @ 50') but I do know this... there are many other challenges unsolved (and largely unaddressed) out there.

Science: Crayfish Can Be Calmed With Anti-Anxiety Medication | American Association for... - 0 views

  • "There have been very few studies of the crayfish brain,"
  • crayfish normally prefer darkness,
  • non-shocked, non-stressed crayfish did.
  • ...1 more annotation...
  • chlordiazepoxide
    • emmarrogers
       
      Do other drugs also work to calm the crayfish's anxiety. Also, in the future, could tests on crayfish be used to find more/ different anxiety medicines in humans. Also, do they show side affects just like humans, or similar that we could document the side affects?

      This is the same medication used in a different study (https://www.aaas.org/news/science-crayfish-can-be-calmed-anti-anxiety-medication) Do only this group of Anti-anxiety medications work in crayfish?

    The description of the experimental design toward the middle of this video... should be inspiring. Simple, yet complex. BOOM. So cool!

    (A pretty fancy piece of equipment is needed here, but I like the concept of this sort of project. Rigorous life science concepts, ability to generate a ton of data, super applicable to real life immediately, etc.)

Crab's Brain Encodes Complex Memories | Scientific American - 1 views

    Two reasons to like this one... both invertebrates & learning/behavioral science tend to be feasible areas for research at our level. Keep reading... more deeply AND more broadly.

Biodegradation of polyethylene by the marine fungus Parengyodontium album - ScienceDirect - 1 views

  • UV light
    • emmarrogers
       
      If we were to use X or Gamma rays, would that speed up the process?
  • Graphical abstract
    • emmarrogers
       
      Why does it need the 9 day incubation period? Could we lower that
    • emmarrogers
       
      So, could we just do this with a plastic bottle?
  • degradation

  • Other important plastic types afloat in the sea are polypropylene (PP) and to a lesser degree polystyrene (PS) and polyethylene terephthalate (PET).

      Does/ Could this fungi degrade these as well
  • Zalerion maritimum (Paço et al., 2017), Alternaria alternata FB1 (Gao et al., 2022) and Rhodotorula mucilaginosa (Vaksmaa et al., 2023a), while Cladosporium halotolerans 6UPA1 was shown to degrade PUR (Zhang et al., 2022).

    Strange.... when I go to this article, I can see your highlights, but I cannot see your comments. Usually, when I can see those, I can comment back right there as opposed to saving it myself. Grrrr...

    Super interesting topic (I saw this one last week). The work with isotopes they did here is well beyond feasibility for us, but that doesn't mean there isn't something here that could be done. You'd have to work through the set up of marine environments (tanks) and acquisition of these fungal strains. I'm betting the one they recently recovered from biofilm on plastic trash in the ocean would be super difficult to get our hands on, but they do mention several others that have previously been found to degrade plastics. perhaps those are more easily obtained. (?) Degredation fo plastic by microbes is EXACTLY what the cheater-guy did in lasy year's winning ISEF project, but like this article says, most of this work has been done with bacteria, not eukaryotic organisms like fungi. I also thing the area of biofilms is super interesting. The analysis (beyond weighing the plastic pre/post) is rather instrumental and that might be difficult depending upon our ability to find someone to help us analyze instrumentally. I like the idea, but feasibility is unknown at the moment. You might want to keep reading down this area. It is certainly interesting and important. Keep an eye on feasibility as you go forward.

Could the world famous Roman Baths help scientists counter the challenge of antibiotic ... - 0 views

  • Proteobacteria and Firmicutes

      If we were able to sample various springs/baths in the midwest could we even culture strains like this, and then what would it take to identify them? You could compare that perhaps to total colony counts on Petri dishes.
  • a detailed examination of the bacterial and archaeal communities found within the waters of the popular tourist attraction in the city of Bath
    • Sean Nash
       
      The Elms is a famous springwater bath locale here in Excelsior Springs, Missouri less than an hour away. Eureka Springs, Arkansas is another area nearby off the top of my head. This also has me asking general questions about other bathing scenarios that would not likely feature ancient microbes, like hot tubs, swimming pools, etc. I wonder about ALL of the variables that go into the conditions of these baths and how that might correlate to total numbers of bacteria as well as differing types. There isn't a TON of microbiology that we can do in the high school lab without help, but I do know that we are generally permitted to work with environmentally-found bacteria (like the little lab we did in the Addie unit).
  • Scientists collected samples of water, sediment and biofilm from locations within the Roman Baths complex including the King's Spring (where the waters reach around 45°C) and the Great Bath, where the temperatures are closer to 30°C.
    • Sean Nash
       
      This means they collected from the water column itself, but also biofilms (which would be found along the edges of containments walls, etc... in addition to sediment found at the bottom of natural spring sources.
  • ...1 more annotation...
  • The samples were then analysed using cutting edge sequencing technology and traditional culturing techniques were employed to isolate bacteria with antibiotic activity.

      This obviously would require a significant bit of outside help. However, I'm still not sure we couldn't do more basic work that would be meaningful.

Q. What's the greener building material, fungus or concrete? - 0 views

    This is more of a broad idea re: the use of living things as building materials - not so much detail in this specific article

Study shows that opportunity costs influence when people leave social interactions - 1 views

    I like this sort of research. Do you think a game like this is either build-able or perhaps even getting access to the one they used? Is it open source? Can you track down this paper? I'm wondering about tying it to depression, etc. That might drift into territory they might not approve at this age (especially since all participants have paperwork they have to sign off on, and any participants under 18 have to have the paperwork signed off by a parent. I wonder if you might dig into introversion/extroversion and whether that might have an impact on similar things. Seems like it might.

    This also makes me think of the UCSD juncos... and how they forage longer in stressful environments due to decreased corticosterone levels....... and how that is a key characteristic allowing them to survive in a human-built environment.
