The Most Iconic Uses of Thermal Optics in Fiction

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.

Report Examines Languages on the Way to Extinction

Published

on

When a language disappears, a worldview, history, and culture fade with it. There are thousands of languages at risk of going extinct, as a report from Preply shows. Their Endangered Languages Report gathers data showing where the crises are most acute, while offering hope that extinction isn’t inevitable. They’ve shown areas where revival is working, too.  The study highlighted problem areas in vanishing languages, the reasons they are in danger, and hopeful signs that languages can be revived.

Most endangered languages to save from extinction

Australia leads the world in the number of critically endangered languages indigenous to its borders (133). In general, the Pacific region and islands have the most endangered languages overall, at 250. Africa has the highest number of threatened languages at 217. In many of these locations, globalization puts pressure on Indigenous and isolated communities. A globalized world pushes young working-age people toward learning a globally dominant language like English or Mandarin, so they have expanded opportunities. It’s worth paying attention to the scale the study creates with at-risk, vulnerable, threatened, endangered, severely endangered, and critically endangered languages. This shows that risk is a spectrum in the world of language, just as it is in plant and animal species.

In the data, a language stands out as a relative success story. Welsh is a vulnerable language, with 19%–20% of the population speaking it. After over 50 years of effort and education, it rose to 30% of children between 3 and 15 years old who spoke it. The nation of Wales set a goal of a million fluent speakers by 2050. If they can meet that goal, it will prove that policy and education can revive a language.

The Lakota language is a cautionary tale of historical oppression. There are only 2,000 speakers today and it’s an endangered language. The United States assimilation policies pushed Indigenous people into residential schools, where children were forced to drop their language and speak English. Today, only 1% of the Lakota population of 170,000 can speak their native language fluently.

Cornish is a rare and unique language brought back from extinction. It officially went extinct in the 1800s, and thanks to a standardized written form revived and adopted in 2008, there are now 557 speakers of a once-dead language.

“Awakening” languages are revivals of once-extinct languages, like Cornish. Kaurna, an Australian language, was nearly lost when the last speaker passed away in 1929. But a program worked to revive it among 50 speakers using dictionaries, songs, and formal education programs. These aren’t the only awakening languages. Wampanoag, Palawa Kani, and Natchez have also awakened back into existence. Revitalization is slow, meticulous work, but these languages show that it’s possible.

Non-native speakers can do their part to support efforts by studying an at-risk language or helping out a revival group. Native speakers carry the heaviest burden and will most effectively save a language by teaching it to their children early. Schools and governments also have a part to play by offering classes in endangered languages. Language survival is possible when ordinary people decide the language is worth speaking.

Preply Presents a Language and Career Mobility Report for 2026

Published

on

The team at Preply has completed its 2026 report on Language and Global Career Mobility. This study was performed across three English-speaking countries and examined why people are moving abroad and what languages they’re learning to prepare for the transition. It’s no secret that learning a second and even a third language can boost career prospects, but this study shows that this is key to helping people achieve their dreams of moving abroad. The survey included 1,800 respondents from the U.S., the UK, and Canada.

Many people aim to move abroad as job opportunities shrink at home. 40% of the survey respondents said their home country’s economy was in decline, and around the same number had either experienced job loss or were close to someone who had lost their job in the past two years. Those dreaming of an adventure outside their country are seeking a fresh start that can help them gain a more secure footing in a career, along with the ability to find new opportunities, grow, and thrive. 92% of people moving abroad said knowing the local language is critical to success.

The survey results are rich with detail. We learned that 63% of Gen Z have experienced job loss in the last 24 months. 81% of people open to relocating to a new country are more likely to do so now than they were two years ago. The biggest motivations for moving are the cost of living and the hope for a better quality of life. 75% say that learning the local language boosted their confidence and certainty about moving. 93% of respondents said they’d take advantage of language learning if their employers offered it. Clearly, there’s a strong willingness to learn new languages!

Moving abroad trends: Preply’s language and global career mobility report 2026

Since the year 2000, international travel has doubled. As traveling abroad becomes more common, life abroad begins to feel more accessible and possible. An enormous 82% of the survey respondents said they were open to moving abroad. Interest is highest in the UK at 87%, followed by the U.S. at 84%, with Canada trailing at 68%. As always, people are interested in moving abroad because they imagine they’ll have a better life there, but the team dug up a few more specific reasons as well. Some people are drawn to the culture, lifestyle, or language of the country they want to move to, while others are drawn to it for its healthcare, market access, and political and economic stability.

Today, many people in major cities around the world are fluent in English, and there are countless apps to aid translation. The benefits of learning a language are clear from this study. The confidence and personal transformations it inspires are priceless. Three in four learners say that learning a new language had a strong impact on their personal growth and even changed their lives. This study strongly underscores the personal empowerment that language learning provides.

Whoever said learning English is difficult and boring hasn’t seen this new study from Preply. It turns out that watching movies can help you improve your English learning, hooray! What better way to learn while having fun than sitting down with a bucket of popcorn and a good movie? Immersing yourself in popular media is a proven way to improve your real-world use of a language. Films can help you practice filling in comprehension gaps using context clues and studying facial expressions and body language for cues. Preply offers us a comprehensive watch guide of the best and worst films for learning English. They analyzed the 150 highest-grossing movies to present popular and enjoyable choices. Their score is based on the average number of words per minute, the difficulty of the vocabulary used, and the ease of watching with subtitles, which makes it easier to follow along.

Best movies for English language learning [Study]

The team found that the best films for learning English are:

  • Dawn of the Planet of the Apes
  • Maleficent
  • The Hobbit: Battle of the Five Armies
  • Spider-Man 3
  • The Hunger Games

Dawn of the Planet of the Apes has a low word count per minute and a simple vocabulary. This action-packed film should be easy to follow for those who don’t understand every word. The same is true of the Disney film, Maleficent, a retelling of Sleeping Beauty from the villain’s point of view.

Popular films that will give English language learners the most trouble are:

  • The Wandering Earth
  • Oppenheimer
  • Barbie
  • Shrek 2
  • Finding Dory

This list has a few surprising results. While it’s no surprise to see the long, heavy, historical drama Oppenheimer on the list, it is funny to see it beside its famous marketing partner, Barbie, a much lighter film that released on the same day. But Barbie is chock-full of banter and musical numbers that add up to a high word count per minute and a frenetic movie for English learners to keep up with. This is the same reason animated films like Shrek 2 and Finding Dory made the list.

The team’s research points to fantasy and adventure films as the best genre for English learning, due to the large, dramatic, action-filled visuals that can help cue the meaning of dialogue. Epic quests and romantic films make for the best storylines. In keeping with these findings, they determined that the franchises best for learning English are The Hobbit films, the Spider-Man series, and the James Bond films. The team also separately emphasized films with high and low word-per-minute rates, which indicate how easy it will be to read the subtitles. Finding Dory is the most difficult to follow (thanks to the chatterbox of a fish in the starring role), and once again, Dawn of the Planet of the Apes comes up on top. This list is a great study tool for English students and one that ESL teachers should bookmark for lesson plans.
