He adds that he doubts that the findings are applicable to other insect species, which still might act purely on instinct.

Do Invertebrates Have Emotions? | The Scientist Magazine® - 1 views
-
-
Invertebrate nervous systems, physiology, and sensory experiences are dissimilar to ours, and designing experiments to measure their emotions has been challenging.
-
If the responses weren’t purely reflexive, it would open up the possibility that the animals could feel pain.

Dams trigger exponential population declines of migratory fish | Science Advances - 0 views
-
When the GD, the first dam across the mainstream of the Yangtze River, was built in the 1970s, the Chinese government explicitly demanded that the dam consider the conservation of fish.
-
Dams can harm migratory fish by disrupting their life cycles and then causing population extinctions.
-
Is it possible to give the fish a different area to migrate to and from?
-
-
We divide the species population into spawning stock (spawners), which are sexually mature adults participating in the current year’s breeding, and recruitment stock, which includes larvae, juveniles, and subadults that have not reached the reproductive age and sexually immature adults/post-spawners that do not participate in the current year’s breeding.

Study traces an infectious language epidemic | ScienceDaily - 0 views
-
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?

Foraging ants navigate more efficiently when given energy-drink-like doses of caffeine ... - 0 views
-
Ants who receive a caffeine-laced sugary reward become more efficient at navigating back to the reward's location compared to ants that only receive sugar. Researchers report on May 23 in the journal iScience that caffeinated ants move toward the reward via a more direct path but do not increase their speed, suggesting that caffeine improved their ability to learn.
-
"The idea with this project was to find some cognitive way of getting the ants to consume more of the poisonous baits we put in the field,"
-
it pushes them into having straighter paths and being able to reach the reward faster

-
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.

Traffic speeds decrease when bike lane is present | ScienceDaily - 0 views
-
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.

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.
Airplane Noise Exposure May Increase Risk of Chronic Disease | SPH - 0 views
-
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.

Picture this: Snapping photos of our food could be good for us - 0 views
-
Research reveals taking pictures of food isn't just content for our social media feeds, but could be the key to improving people's diets
-
I just have a gut feeling that, over time, if you knew you were going to photograph every meal, you would tend to eat less, eat more colorful things, and eat more varied things... so that it would make a better photograph. Each of those elements might just lead to healthier meals over time. Very interesting. It is sort of like imposing a metacognitive approach to food selection.
