How Optical Tech Enhances Filmmaking
In the film Predator, infrared optics are a prominent feature of the storyline. An advanced race of aliens used infrared to better hunt for sport in terrifying twists and turns. But the filmmakers used infrared to their own benefit, too. They portrayed the aliens’ infrared vision by using an Inframetrics thermal video scanner to bring the vision to life. The film is full of optical challenges that director Joel Hynek overcame in fascinating ways, including the aliens’ unique camouflaging effect.
The team’s chart includes a recent and powerful sci-fi film example, Dune 2. In the film, the planet Giedi Prime is portrayed in a haunting grayscale that enhances its brutal, joyless atmosphere. The film’s director, Denis Villeneuve, used a groundbreaking technique to achieve the effect. He filmed in infrared and then removed saturation in post-production to create a unique, almost ghostly, ethereal appearance for the actors, along with a stark, sharp grading for the architecture and scenery. The technique is now known as “The Harkonnen Effect.”
Infrared technology is especially powerful when filming military movies. For example, in the Oscar-winning Zero Dark Thirty, filmmakers blended infrared light with night vision optics to create a tense atmosphere that reflected the gritty world of Navy SEAL warfare for the film’s dramatic climax. Filmmakers used infrared for a similar effect in the A24 film Zone of Interest. In the infrared scene, a woman sneaks through the cover of night to leave food for Auschwitz prisoners during the Holocaust. The director chose infrared lighting to show the act as a small, hopeful point of light during a period of intense darkness.
Optical Technology as a Plot Point
From the silly to the scary, the chart also thoroughly covers examples of optical technology used to enhance the plot or define a character. The team highlights superheroes like Daredevil and Superman. Superman uses infrared vision to store solar energy in his eyes and blast lasers at his foes, while Daredevil uses his superior senses to create a mental heat map that helps him overcome blindness. Nick Fury sports a pair of infrared glasses in Marvel’s Secret War series. The beloved cartoon alien Stitch from Disney’s Lilo & Stitch boasts a long list of special abilities, including heat vision that causes his eyes to glow red.
Plenty more military films are featured here, too, starring characters from the armed services who use real technology to overcome tremendous odds. Some of the weapons featured include a Barrett M82A1, PVS-7 goggles, and Accufire Incendis.
Pulsar’s roundup of optical technology used in film does a perfect job of demonstrating both realistic and imaginative uses of the tech, as well as demonstrating the ways filmmakers have applied new optical technology to cameras to push the limits of special effects and filmmaking.

A Hidden Health Crisis: Where Children Drink the Most Soda
A new study from the PA Requirements team unveiled regional patterns in children’s soda consumption across the U.S. Some states have consumption rates up to five times higher than others, revealing some truly alarming statistics. The map is based on the CDC’s Youth Risk Behavior Survey, which included 42 states in a week-long analysis of soda drinking behavior. The end result is a map that paints a concerning picture of soda consumption among American children.

West Virginia is at the top of the list, with 22.5% of high schoolers there reporting that they drank soda twice or more every day. That’s one in four West Virginia teens having several sodas every single day. Kentucky is close behind, with 18.5% of teens drinking multiple sodas, followed by Mississippi at 17.1%. These numbers seem especially high compared to the state with the lowest consumption, Massachusetts. Only 4.9% of teenagers there reported drinking multiple sodas a day.
The survey asked students to report their soda consumption with one of three answers each day: didn’t drink any soda, drank one soda, or drank two or more sodas. Responses show that children in Southern states drank the most soda.
Unfortunately, the results show us more than beverage preferences. There are a lot of health implications we can glean from these results. One soda contains 7 to 10 teaspoons of sugar, comprised of high-fructose corn syrup. For small children, the impacts of consuming so much processed sugar are even more pronounced. High sugar consumption is linked to obesity, dental disease, sleep disruption, and type 2 diabetes.
Children are also more prone to developing a sugar addiction. Drinking too much sugar leads children to develop a sugar addiction and symptoms of excessive sugar consumption, which include weight gain, mood swings, and trouble focusing.
The map colors show us a “sugar belt” across the Southern United States, with seven of the top highest consuming states located in the South. Research has shown that education impacts nutritional choices as well as income levels. Some of the states on the high end of the spectrum have lower public school ratings and high poverty levels, so it seems this isn’t coincidental. Culture may play a part as well. With many soda companies originating in the South, it might be that Southerners enjoy soda more and have normalized having a soda with meals.
Understanding soda consumption rates and health risks can help parents and educators make informed decisions about health choices for children. We don’t always realize how much soda we’re consuming until we look at hard data like this. This map and research underscore the need for soda-drinking interventions, especially in certain regions. While soda is a good treat, it’s not intended to be drunk daily, especially not for children. Through studies like this, awareness, and education, we can improve the health of American children.

New Map Displays the Geography of Desire
When dating apps connect people all around the world, sparking more long-distance relationships than ever, this prompts a fascinating question: does region affect what we find attractive? A new study from NapLab sheds some light on the answers, revealing that location does seem to affect what features Americans find most attractive.
Click below to zoom.
The survey had 1,012 participants across 50 states. Their approach was straightforward, asking participants three questions: which body part do you find most attractive on others, what is your gender, and what state do you live in? This method allowed the team to map out the results across America, showing us patterns based on location while challenging some of what we thought we knew about universal standards of beauty.
The research reinforced some of what we already know about what different genders find most attractive. For example, men are believed to be most drawn to features associated with fertility. This held true in the NapLab study, showing that 25.82% of men are most attracted to buttocks and 20.60% are most attracted to breasts.
Women are thought to be drawn to more emotional aspects of a relationship, which holds true in what they’re attracted to. The study showed women being most drawn to expressive features, with 26.10% saying they find the face most attractive, 26.09% favoring eyes, and 17.39% answering smile.
This research helps show how factors beyond biology could influence attraction. Climate might play a role, as we can see from Hawaii’s results. Its tropical climate and plentiful beaches mean more skin exposed and a bigger emphasis on physical fitness. Hawaii was the only state in which women found abs most attractive. In some of the rural states, men were predominantly attracted to buttocks. On the opposite end of the spectrum, more conservative states seemed more hesitant to express sexual attraction, stating that they found smiles and eyes most attractive. This indicates that religious background and other cultural norms can affect what people are attracted to or what they admit feeling attracted to.
Despite these variations, there were things that Americans had in common across the nation. Almost no respondents said they were most attracted to skin, feet, or hands. Neck and jawline received zero votes. It seems there are some biologically driven constants that geography doesn’t change.
This research shows that there is no universal agreement on what features are most attractive. There’s already been plenty of scientific research on what we’re biologically attracted to and why, but this study shows other factors might be in play. While some of our feelings are driven by biological impulses, it’s clear that culture, climate, and other regional factors change what we’re attracted to. This is a fun study for couples to discuss together, as well as giving armchair sociologists some food for thought. Find many more intriguing insights in the details of this map!

Study Analyzes Kindergarten Measles Vaccination Gaps Across America
As of April 2025, there have been 16 measles outbreaks in the United States, a number that has jumped significantly over the past few years. A new study from PA Requirements shows this has a connection to vaccination gaps. Kindergarten vaccinations help protect citizens against diseases like measles and contribute to our population achieving herd immunity, which eradicates the threat of the disease. However, the team’s study reveals that a combination of policy, vaccine access, and community factors is hindering our progress toward this goal.
Click below to zoom.
The team found that these states had the highest percentage of children not vaccinated for measles:
- Idaho: 20.4%
- Alaska: 15.7%
- Wisconsin: 15.2%
- Minnesota: 13.0%
- Florida: 11.9%
- Oklahoma: 11.7%
- Colorado: 11.7%
- Utah: 11.2%
- Iowa: 10.9%
- Ohio: 10.8%
It can be useful to compare these numbers to the states with the lowest rates of unvaccinated children:
- West Virginia: 1.7%
- New York: 2.3%
- Connecticut: 2.3%
- Mississippi: 2.5%
- Maine: 2.5%
- Rhode Island: 2.9%
- Maryland: 3.4%
- Massachusetts: 3.7%
- California: 3.8%
We can observe some interesting regional patterns by examining the map, such as lower vaccination rates in the Midwest and Southwest.
Among the states with high rates of vaccination, we find that these five states don’t allow non-medical vaccination exemptions: Maine, New York, West Virginia, Connecticut, and California. It’s no surprise that stricter policies lead to a greater number of vaccinations. Among states with lower rates, we find more relaxed laws that allow for greater exemptions on the basis of religion, philosophy, and other personal reasons. Comparing each state to its neighbors reveals patterns and trends that might imply cultural differences affecting vaccination rates in different regions. We can look for locations with a high prevalence of religions that outlaw vaccines to identify reasons for the numbers on the map. Check the numbers on the states with the largest cities, and you might find stricter vaccination laws there to help prevent disease spread in population-dense areas.
There’s no doubt that state policies correlate directly with vaccination rates when we look at the numbers presented on the team’s graphic. Many states require certain vaccinations, like measles, in order to enroll in public school. These laws and requirements also directly impact vaccination rates. Looking at insurance costs and access to vaccine clinics in rural areas may also reveal why some areas have more unvaccinated children than others. Some states have created initiatives to encourage vaccination and provide education, leading to higher vaccination rates.
Overall, studies like these greatly benefit public health by increasing awareness and education about diseases like measles. People who shy away from vaccines often find them untrustworthy. The only way to convince them otherwise is to answer their questions and present them with transparent data that’s easy to understand, just like the information shown in this graphic, regarding the risks associated with declining vaccines. These studies provide policymakers, parents, and public health officials with more information to make informed decisions for the health of their children and communities.
