  • This year has already seen massive heatwaves around the globe, with cities in Mexico, India, Pakistan and Oman hitting temperatures near or past 50 degrees Celsius (122 degrees Fahrenheit).
  • In tests under the Arizona sun, the material kept 2.3 degrees Celsius (4.1 degrees Fahrenheit) cooler than the broadband emitter fabric used for outdoor endurance sports and 8.9 degrees Celsius (16 degrees Fahrenheit) cooler than the commercialized silk commonly used for shirts, dresses and other summer clothing.
  • "You can save a lot of cooling, electricity and energy costs because this is a passive process," Sui said.

      I'm not yet convinced of the feasibility of this one, but this might provide a spark for someone. Some types of materials engineering like this is done on a nanoscale, which may not be the best for what we can do... but I believe there is space here for exploring composite materials with different properties to engineer better outcomes than what we're currently dealing with.

      Where is the limit between a reflex and a cognitive response?
  • Sean Nash on 01 Jul 24
     
    I really like this topic, and it is one that is getting some current attention. so, we obviously cannot discern cellular-level factors with the nervous system of animals (and obviously- especially when dealing with pain response, we would have to work exclusively with invertebrates and the experimental design would have to be very well thought out. That said, behavioral studies where you have a really tight experimental design set up.... and you're recording behavioral changes... is likely feasible. If this is interesting, keep digging into pain vs. reflex studies, and also begin to look at invertebrate models that we can both successfully raise... and that have interesting behavioral responses we can readily discern in the lab.

    Super interesting, and relatively simple topic. If this was looking at bacteria normally found environmentally in the kitchen, we could easily get approved. We could even culture those. The thing that makes this difficult to do at school is the fact that this is all about viruses. Detecting these in our lab would be super difficult. I'm also not sure if we could even get a culture of virally-infected cells to perform controlled studied. This one is a "maybe."

    Fungi as a soil conditioner is an interesting topic. This is something Eli Jenkins was looking into last year, although his attempts at growing the plants he wanted (he got started very late) kept him from really testing the product he wanted to test. I have also seen other commercial soil treatments meant to break down clay soils and keep water from pooling at the top of the soil.

  • When leaf beetle larvae eat goldenrod leaves, the plant emits a chemical that informs the insect that the plant is damaged and is a poor source of food. These airborne chemicals, called volatile organic compounds (VOCs), are also picked up by neighboring goldenrod plants, prompting them to produce their own defenses against the beetle larvae. In this way, goldenrod move herbivores on to neighbors, and distribute damage.

      Are these VOCs (volatile organic compounds) detectable by us? If not detectable, they can we identify them... and then produce or purchase those chemicals to test their effects on plant responses?
  • start producing defensive compounds that help the plants fight off insect pests.

      It seems to me that I remember hydrogen peroxide being one of these signaling chemicals (at least from one part of a plant to another).
  • When no neighbors are present, the plants don't resort to accelerated growth when eaten and the chemical responses to herbivores are markedly different, though they still tolerate quite high amounts of herbivory.
  • ...5 more annotations...
  • Neighboring goldenrod also exhibit intelligence when they perceive VOCs that signal the presence of a pest. "The volatile emission coming from a neighbor is predictive of future herbivory," Kessler said. "They can use an environmental cue to predict a future situation, and then act on that."
  • Applying the concept of intelligence to plants can inspire fresh hypotheses about the mechanisms and functions of plant chemical communication, while also shifting people's thinking about what intelligence really means, Kessler said.
  • "What that means is, the brain in the plant is the entire plant without the need of central coordination," Kessler said.
  • "They can smell out their environment very precisely; every single cell can do it, as far as we know,"

    "When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby."

    I think this shows tons of promise for feasibility- especially since we have an international airport nearby, and measuring sound is straightforward. Acquiring the data acquisition probes to do this is certainly feasible. A lot of room for creativity here. If this is interesting, also dig into ARC-GIS as a tool to geographically map out the sound data generated.

  • Many contemporary studies have used methods designed to study dogs—a poor proxy, as our furry friends have fewer facial expressions than their ancestors.
  • (These techniques have previously been used to study facial expressions in cats.)
  • These expressions were common to all of the gray, arctic, and Canadian wolf packs the researchers observed.
