  • They worked with a local food processing company to rescue hundreds of liters of soybean wastewater, which they discovered was rich in two types of protein-accumulating microbes in particular, known as Acidipropionibacterium and Propioniciclava.

  • The sea bass that were fed the alternative microbe protein diet did have significantly lower weight to begin with, but that evened out as they grew. And, notably, the group that received the traditional feed diet had greater variability in their weight gain as they grew—whereas those fed the alternative microbe protein diet showed a more even accumulation of weight over the experiment’s course.
  • Meanwhile, the wastewater from other soybean uses goes unused—but according to the recent results, could feasibly tackle both of these sustainability challenges at once. Furthermore it’s not just soybean waste water, the researchers say: several agricultural processes create wastewater side streams that are rich in the combination of carbon, nitrogen, and phosphorus that’s needed to sustain a growing population of hungry, protein-accumulating bacteria.
  • Microbial community‐based protein from soybean‐processing wastewater as a sustainable alternative fish feed ingredient.

  • Rho's work is grounded in a social science framework called Fuzzy Trace Theory that was pioneered by Valerie Reyna, a Cornell University professor of psychology and a collaborator on this Virginia Tech project. Reyna has shown that individuals learn and recall information better when it is expressed in a cause and effect relationship, and not just as rote information. This holds true even if the information is inaccurate or the implied connection is weak. Reyna calls this cause-and-effect construction a "gist."

      Fuzzy Trace Theory looks interesting for this, and perhaps many other reasons. I want to learn more about this myself, and I'm wondering if this theory could be put to work in other potential behavioral science projects. What do you think?

  • people who were exposed to higher levels of noise from aircraft were more likely to have a higher body mass index, an indicator for obesity that can lead to stroke or hypertension. The findings highlight how the environment—and environmental injustices—can shape health outcomes
  • self-reported body mass index (BMI)
  • The study is the first to explore a connection between aircraft noise exposure and obesity nationwide in the United States; past studies on this subject have focused on European populations, and results have varied

      It would be interesting to see how these studied varied. I would bet that there are other, stronger factors overlying this effect, and it would be challenging to tease out this signal from other socioeconomic factors, but I very much like this concept.
  • ...8 more annotations...
  • “Prior research has shown that aircraft noise can elevate stress responses and disturb sleep, but there has been mixed evidence of any links with body mass index,” says study lead and corresponding author Matthew Bozigar, assistant professor of epidemiology at OSU and a former postdoctoral associate at SPH. “We were surprised to see a fairly robust link between aircraft noise and higher body mass index among women across the US.”
  • These new findings underscore the role of the environment on one’s risk of chronic disease.
  • Junenette Peters, associate professor of environmental health, and colleagues examined airplane noise exposure and self-reported BMI and other individual characteristics among nearly 75,000 participants living around 90 of the major US airports
  • The team examined aircraft noise levels every five years from 1995 to 2010, using a day-night estimate (DNL) that captures the average noise level over a 24-hour period and applies a 10 dB adjustment for aircraft noise occurring at night, when background noise is low.

      I'm sure there are low-powered data loggers that measure dB that we could plant in various places (varying distances from airports (or other things... even just distances from population centers in general). This would allow us to not only work with and search for correlations between data points already collected, but also to generate more specific data on our own. The human data might not necessarily have to be collected by us. The challenge might be just to find databases that have already been collected for various reasons. Much science is done in this way, where instead of generating a ton of data to analyze, the researcher used previously collected data to ask new and interesting questions of.
  • Although the team acknowledges that BMI is a suboptimal metric, the independent and strong association between more aircraft noise exposure and higher BMI that they observed is notable.
  • “We can only hypothesize about why we saw these regional variations, but one reason may relate to the era of regional development, building characteristics, and climate which may affect factors such as housing age, design, and level of insulation,” says Peters. “Regional differences in temperature and humidity may influence behaviors such as window opening, so perhaps study participants living in the West were more exposed to aircraft noise due to open windows or housing type, which allowed more noise to penetrate.”

      The really interesting work here would be teasing interesting patterns out of really complex data sets. For example, people living near airports typically live in housing that is less expensive due to the lesser desirability of living in that area. That tends to correlate with lower socio-economic status found near airports. However, this is interesting because the major flightpaths to the KCI airport do not exactly line up in this way. For example, three of the school districts in Missouri that line up with KCI runways (Park Hill Schools - where we live, Platte County Schools, Kearney Schools, Smithville Schools, and the northern part of North Kansas City Schools) are all of a higher than average socioeconomic status than outlying areas closer to the city. This is unusual in major metropolitan areas.
  • Previous data suggest that Black, Hispanic, and low-income populations are disproportionately exposed to aircraft noise. The participants in the NHS study groups were primarily White and of mid-level socioeconomic status. 
    • Sean Nash
      Sean Nash on 06 Jun 24
       
      Again, this is a bit different than around most airports. The area immediately surrounding KCI is rather white and mid-to-upper SES.
  • “We need to study the potential health impacts of environmental injustices in transportation noise exposures alongside other environmental drivers of poor health outcomes” Bozigar says. “There is a lot more to figure out, but this study adds evidence to a growing body of literature that noise negatively impacts health.”

      What other environmental factors can be studied either by direct measurement, or by querying previously-collected data to ask/answer questions about environmental health?

  • researchers have designed a new wearable fabric to help people beat the heat in urban settings. The material, reported in the journal Science, could find use in clothing, cooling facades for buildings and cars, and for food storage and transport.
  • Existing cooling fabrics reflect sunlight and also wick away sweat to cool a person via evaporation. More recently, researchers have designed cooling fabrics that rely on the principle of radiative cooling: the natural phenomenon in which objects radiate heat through the atmosphere straight into outer space.
  • But radiative cooling fabrics made so far are designed to work when laid horizontally as opposed to vertically, as they would be when worn.

  • researchers at the University of Chicago made a new three-layer fabric. Its wool bottom layer wicks heat from the skin to the middle layer, which is made of silver nanowires that block heat from coming in. The top layer selectively emits heat into the atmosphere.
  • In tests conducted in the urban heat island of Chicago and under blistering Arizona sun, the material stayed 2.3°C cooler than sports cooling fabrics and 8.9°C cooler than commercial silk used for summer clothing.

    Materials science is certainly a nifty bit of engineering. This is the second time I've seen this study mentioned. Look interesting enough to dig into various materials and how they might be combined to serve a key purpose?

  • Researchers conducting a study at a high-traffic intersection in a Jersey Shore town have found that the installation of a bike lane along the road approaching the convergence reduced driving speeds.
  • "We are giving you more evidence that bike lanes save lives,"
  • The research team started by creating a temporary bike lane on Cookman and Asbury Avenues on the side of the road heading toward the beach, delineating it with orange road cones.

      Though you COULD NOT do something this manipulative, you COULD contact municipalities nearby and inquire about current and near-future efforts to install bike lanes... and THEN collect pre-and most traffic data in real-time. This would be quite feasible and super interesting. It would be all about doing the legwork to find where these design changes are being made, and of course the timing of it all.
  • ...3 more annotations...
  • They found that the presence of the delineated bike lane made a difference: a 28 percent reduction in average maximum speeds and a 21 percent decrease in average speeds for vehicles turning right.
  • In addition, drivers moving at a perpendicular angle to the bike lane did not slow down.
  • With pedestrian deaths rising nationally, a study such as this could contribute to the development of new traffic policies or the reversal of older ones, Younes said.

  • 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?

      Ok.... this screams "potential research idea."
  • “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.”
  • 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.
  • Nishizono and colleagues mounted eye trackers on the helmets of three drivers and had them drive three Formula circuits
  • 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.

    This is an interesting possibility for working with large (already-existing) datasets to map out and correlate data about the spring reset for plants. What factors are most important in when the spring "greenup" starts? Could also be combined with some local data collected to compare the datasets with what we are seeing on the ground. Could also be a cool opportunity to use ArcGIS tools for spatially mapping information geographically over time!
