    Save these for later this year. You will likely use resources like this to aid in your diagrams/models for your display.

  • Butterflyfishes, which are facultative corallivores in this region, have even been found to prefer SCTLD-infected coral

      Some species like the infected coral Maybe it has different properties or something

    You know, there are repositories of publicly available image/video data from coral reef surveys.... somewhere online. They make them available for people to devise creative ways of pulling data out of such raw material. Might be something to look into.

    "Abstract The decapitated primary root of 3-day-old Alaska pea seedlings has been used as a test system to determine the activities on lateral root formation of six auxins, six cytokinins and several other naturally-occurring compounds. Their effects were assessed on (1) the initiation of lateral root primordia, (2) the emergence of visible lateral roots, and (3) the elongation of these laterals. All the auxins, at the optimum concentration of 10-4M, promoted the initiation of lateral root primordia, and all except 3-indolylpropionic acid inhibited the elongation of the resulting lateral roots. Their effects on the emergence of laterals were small and varied. All the cytokinins, at 10-6M and above, inhibited both the initiation and the emergence of lateral roots, zeatin being the most powerful inhibitor. The emergence process was about twice as sensitive as the initiation of primordia to the presence of cytokinins. The cytokinin ribosides were generally less active than the free bases. Abscisic acid and xanthoxin inhibited both emergence and elongation, the concentration for 50% decrease of emergence being about 10-4M. Gibberellic acid had little clear effect on any of the three criteria. Nicotinic acid and thiamine at 10-3M promoted both the initiation of primordia and their emergence: pyridoxal phosphate stimulated both emergence and elongation but did not influence the initiation of primordia. Adenine and guanine had little effect but decreased root elongation some 25%. The strong inhibiting effect of the cytokinins may well be the basis for the marked inhibition exerted by the root-tip on lateral root formation, while the promoting effects of auxins may explain the previously observed promotion of lateral root formation by the young shoot and cotyledons."

  • Scientists studying ultra-processed foods have created a new tool for assessing the rewarding and reinforcing properties of foods that make up 58 percent of calories consumed in the United States. The foods have been linked to a wide range of negative health outcomes.

      I couldn't locate this imageset and associated tools online, but I am willing to bet they might make it available to us, and the generation of more future research in this area is a key purpose of this work.
  • provides a collection of carefully curated images of minimally processed and ultra-processed foods matched on 26 characteristics, including macronutrients, sodium, dietary fiber, calories, price, and visual characteristics such as a color and portion size

      Perhaps we just need to get the full journal article to get the raw materials (images) created and used.
  • The scale has its detractors. "A major criticism of the NOVA scale is that it's difficult to use or that foods are classified differently by different people," said Alexandra DiFeliceantonio, corresponding author and assistant professor at the Fralin Biomedical Research Institute. "We found that people with education in nutrition generally agreed on the food classifications, providing some data that it might not be a valid criticism."

      See... this is the sort of thing I see as an opportunity. If the scale has detractors or isn't yet perfect, perhaps there is an opening here for a project. Perhaps there is even an opening to create something focused on teens (who I would argue are at most risk for the consumption of ultra-processed foods). This is an interesting area to me, not only behavioral science, but human diet in general.

  • To develop the picture set, a team of psychologists, neuroscientists, and registered dietitians selected foods to represent either minimally processed or ultra-processed foods.
  • The foods were prepared in a lab, visually represented through professional photography, and controlled for consistency. Researchers also gathered price, food weights, and nutritional information -- calories, macronutrients, sodium, and dietary fiber -- for the food in each image.
  • researchers recruited 67 nutrition professionals and asked them to classify the foods as minimally or ultra-processed
  • "There is very little experimental research on ultra-processed foods, and part of what's been holding us back is better tools for measuring and assessing their effects,"

      Another big GREEN flag that this is an area ripe for new and creative approaches!
  • The Virginia Tech team is making the pictures and associated data accessible through the Virginia Tech Data Repository of the Virginia Tech University Libraries. This will allow scientists to test hypotheses in behavioral economic and neuroimaging studies.

      This states that the images/research tools WILL BE MADE AVAILABLE (if not already). This is very cool. So, could the already-existing tool be leveraged in a novel way compared to what the researchers used it for, or does this provide somewhat of a template for someone to create a better or more-helpful tool perhaps for teens?

    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!
