It’s been the biggest year for elections in human history: 2024 is a “super-cycle” year in which 3.7 billion eligible voters in 72 countries had the chance to go the polls. These are also the first AI elections, where many feared that deepfakes and artificial intelligence-generated misinformation would overwhelm the democratic processes. As 2024 draws to a close, it’s instructive to take stock of how democracy did.

In a Pew survey of Americans from earlier this fall, nearly eight times as many respondents expected AI to be used for mostly bad purposes in the 2024 election as those who thought it would be used mostly for good. There are real concerns and risks in using AI in electoral politics, but it definitely has not been all bad.

The dreaded “death of truth” has not materialized – at least, not due to AI. And candidates are eagerly adopting AI in many places where it can be constructive, if used responsibly. But because this all happens inside a campaign, and largely in secret, the public often doesn’t see all the details.

Connecting with voters

One of the most impressive and beneficial uses of AI is language translation, and campaigns have started using it widely. Local governments in Japan and California and prominent politicians, including India Prime Minister Narenda Modi and New York City Mayor Eric Adams, used AI to translate meetings and speeches to their diverse constituents.

Even when politicians themselves aren’t speaking through AI, their constituents might be using it to listen to them. Google rolled out free translation services for an additional 110 languages this summer, available to billions of people in real time through their smartphones.

Other candidates used AI’s conversational capabilities to connect with voters. U.S. politicians Asa Hutchinson, Dean Phillips and Francis Suarez deployed chatbots of themselves in their presidential primary campaigns. The fringe candidate Jason Palmer beat Joe Biden in the American Samoan primary, at least partly thanks to using AI-generated emails, texts, audio and video. Pakistan’s former prime minister, Imran Khan, used an AI clone of his voice to deliver speeches from prison.

Perhaps the most effective use of this technology was in Japan, where an obscure and independent Tokyo gubernatorial candidate, Takahiro Anno, used an AI avatar to respond to 8,600 questions from voters and managed to come in fifth among a highly competitive field of 56 candidates. https://www.youtube.com/embed/N9GaiEgWjlE?wmode=transparent&start=0 ‘AI Steve’ was an AI persona who ran for office in the 2024 U.K. election.

Nuts and bolts

AIs have been used in political fundraising as well. Companies like Quiller and Tech for Campaigns market AIs to help draft fundraising emails. Other AI systems help candidates target particular donors with personalized messages. It’s notoriously difficult to measure the impact of these kinds of tools, and political consultants are cagey about what really works, but there’s clearly interest in continuing to use these technologies in campaign fundraising.

Polling has been highly mathematical for decades, and pollsters are constantly incorporating new technologies into their processes. Techniques range from using AI to distill voter sentiment from social networking platforms – something known as “social listening” – to creating synthetic voters that can answer tens of thousands of questions. Whether these AI applications will result in more accurate polls and strategic insights for campaigns remains to be seen, but there is promising research motivated by the ever-increasing challenge of reaching real humans with surveys.

On the political organizing side, AI assistants are being used for such diverse purposes as helping craft political messages and strategy, generating ads, drafting speeches and helping coordinate canvassing and get-out-the-vote efforts. In Argentina in 2023, both major presidential candidates used AI to develop campaign posters, videos and other materials.

In 2024, similar capabilities were almost certainly used in a variety of elections around the world. In the U.S., for example, a Georgia politician used AI to produce blog posts, campaign images and podcasts. Even standard productivity software suites like those from Adobe, Microsoft and Google now integrate AI features that are unavoidable – and perhaps very useful to campaigns. Other AI systems help advise candidates looking to run for higher office.

Fakes and counterfakes

And there was AI-created misinformation and propaganda, even though it was not as catastrophic as feared. Days before a Slovakian election in 2023, fake audio discussing election manipulation went viral. This kind of thing happened many times in 2024, but it’s unclear if any of it had any real effect.

In the U.S. presidential election, there was a lot of press after a robocall of a fake Joe Biden voice told New Hampshire voters not to vote in the Democratic primary, but that didn’t appear to make much of a difference in that vote. Similarly, AI-generated images from hurricane disaster areas didn’t seem to have much effect, and neither did a stream of AI-faked celebrity endorsements or viral deepfake images and videos misrepresenting candidates’ actions and seemingly designed to prey on their political weaknesses. https://www.youtube.com/embed/qs05muNU5dg?wmode=transparent&start=0 Russian intelligence services aimed to use AI to influence U.S. voters, but it’s not clear whether they had much success.

AI also played a role in protecting the information ecosystem. OpenAI used its own AI models to disrupt an Iranian foreign influence operation aimed at sowing division before the U.S. presidential election. While anyone can use AI tools today to generate convincing fake audio, images and text, and that capability is here to stay, tech platforms also use AI to automatically moderate content like hate speech and extremism. This is a positive use case, making content moderation more efficient and sparing humans from having to review the worst offenses, but there’s room for it to become more effective, more transparent and more equitable.

There is potential for AI models to be much more scalable and adaptable to more languages and countries than organizations of human moderators. But the implementations to date on platforms like Meta demonstrate that a lot more work needs to be done to make these systems fair and effective.

One thing that didn’t matter much in 2024 was corporate AI developers’ prohibitions on using their tools for politics. Despite market leader OpenAI’s emphasis on banning political uses and its use of AI to automatically reject a quarter-million requests to generate images of political candidates, the company’s enforcement has been ineffective and actual use is widespread.

The genie is loose

All of these trends – both good and bad – are likely to continue. As AI gets more powerful and capable, it is likely to infiltrate every aspect of politics. This will happen whether the AI’s performance is superhuman or suboptimal, whether it makes mistakes or not, and whether the balance of its use is positive or negative. All it takes is for one party, one campaign, one outside group, or even an individual to see an advantage in automation.

(Family Features) The Ardennes Offensive, commonly known as the “Battle of the Bulge,”  stands as the single bloodiest battle fought by the United States during World War II. Waged in the bitter cold of mid-December 1944, it took the Allies a month to secure victory. The cost was staggering: nearly 20,000 Americans were killed in action, close to 50,000 wounded and another 20,000 captured.

In honor of the 80th anniversary of this pivotal battle, the Library of Congress Veterans History Project has launched an online exhibit to commemorate the milestone. While the battle itself is etched in the annals of history, the personal stories from those who endured it remain one of the most powerful testaments to its impact.

The online exhibit, “Serving Our Voices,” features accounts from 12 Battle of the Bulge survivors, part of the thousands of narratives preserved by the project. These stories ensure future generations can gain deeper understanding of veterans’ service and sacrifice.

One such story includes Eliot Annable, a 20-year-old radio operator serving with the Army’s 106th Infantry Division. Just days after arriving at the western front, Annable found himself under German artillery barrages on. Dec. 16, 1944. He recalled the assault in his oral history, describing the intensity as “almost enough to knock you on the floor.”

The following five days became the most harrowing days of Annable’s military service. While on a communications mission, he became stranded behind enemy lines and spent nearly a week evading the enemy in the Ardennes Forest without food, shelter or appropriate winter clothing. After traveling more than 30 miles, he eventually safely rejoined the remnants of his unit.

Back home, Annable’s parents were gripped by uncertainty. On Dec. 31, 1944, his father wrote a letter expressing the family’s anguish and love for their son, regardless of what happened. The moving letter, coupled with Annable’s oral history, provides an intimate view into one soldier’s Battle of the Bulge experience.

Another featured veteran in the exhibit, Guy Martin Stephens, also served with the 106th Infantry Division. Unlike Annable, Stephens was captured by the Germans during battle. In his oral history, he recounted the surreal feeling of combat, the relentless hunger he endured as a prisoner of war and the lingering effects of his time in captivity.

“It’s hard,” Stephens said. “It’s something you can’t ever … your mind is just like a video, or camcorder, I guess. You put it in there. You get busy and get married. You get home, and you get an education, and get a job, and raise your family and everything like that. You can kind of gloss it over or try to push it back, but it’s always there, you know?”

Veterans who served during the 20th or 21st centuries are invited to establish a collection, including interviews (video or audio), letters and original photographs, even if they did not see combat. Families can also submit collections posthumously to honor their loved ones. To explore more veterans’ stories and learn how you can contribute to the program, visit loc.gov/vets.

The NASA project NEOWISE, which has given astronomers a detailed view of near-Earth objects – some of which could strike the Earth – ended its mission and burned on reentering the atmosphere after over a decade.

On a clear night, the sky is full of bright objects – from stars, large planets and galaxies to tiny asteroids flying near Earth. These asteroids are commonly known as near-Earth objects, and they come in a wide variety of sizes. Some are tens of kilometers across or larger, while others are only tens of meters or smaller.

On occasion, near-Earth objects smash into Earth at a high speed – roughly 10 miles per second (16 kilometers per second) or faster. That’s about 15 times as fast as a rifle’s muzzle speed. An impact at that speed can easily damage the planet’s surface and anything on it.

Impacts from large near-Earth objects are generally rare over a typical human lifetime. But they’re more frequent on a geological timescale of millions to billions of years. The best example may be a 6-mile-wide (10-kilometer-wide) asteroid that crashed into Earth, killed the dinosaurs and created Chicxulub crater about 65 million years ago.

Smaller impacts are very common on Earth, as there are more small near-Earth objects. An international community effort called planetary defense protects humans from these space intruders by cataloging and monitoring as many near-Earth objects as possible, including those closely approaching Earth. Researchers call the near-Earth objects that could collide with the surface potentially hazardous objects.

NASA began its NEOWISE mission in December 2013. This mission’s primary focus was to use the space telescope from the Wide-field Infrared Survey Explorer to closely detect and characterize near-Earth objects such as asteroids and comets.

NEOWISE contributed to planetary defense efforts with its research to catalog near-Earth objects. Over the past decade, it helped planetary defenders like us and our colleagues study near-Earth objects.

Detecting near-Earth objects

NEOWISE was a game-changing mission, as it revolutionized how to survey near-Earth objects.

The NEOWISE mission continued to use the spacecraft from NASA’s WISE mission, which ran from late 2009 to 2011 and conducted an all-sky infrared survey to detect not only near-Earth objects but also distant objects such as galaxies.

The spacecraft orbited Earth from north to south, passing over the poles, and it was in a Sun-synchronous orbit, where it could see the Sun in the same direction over time. This position allowed it to scan all of the sky efficiently.

The spacecraft could survey astronomical and planetary objects by detecting the signatures they emitted in the mid-infrared range.

Humans’ eyes can sense visible light, which is electromagnetic radiation between 400 and 700 nanometers. When we look at stars in the sky with the naked eye, we see their visible light components.

However, mid-infrared light contains waves between 3 and 30 micrometers and is invisible to human eyes.

When heated, an object stores that heat as thermal energy. Unless the object is thermally insulated, it releases that energy continuously as electromagnetic energy, in the mid-infrared range.

This process, known as thermal emission, happens to near-Earth objects after the Sun heats them up. The smaller an asteroid, the fainter its thermal emission. The NEOWISE spacecraft could sense thermal emissions from near-Earth objects at a high level of sensitivity – meaning it could detect small asteroids.

But asteroids aren’t the only objects that emit heat. The spacecraft’s sensors could pick up heat emissions from other sources too – including the spacecraft itself.

To make sure heat from the spacecraft wasn’t hindering the search, the WISE/NEOWISE spacecraft was designed so that it could actively cool itself using then-state-of-the-art solid hydrogen cryogenic cooling systems.

Operation phases

Since the spacecraft’s equipment needed to be very sensitive to detect faraway objects for WISE, it used solid hydrogen, which is extremely cold, to cool itself down and avoid any noise that could mess with the instruments’ sensitivity. Eventually the coolant ran out, but not until WISE had successfully completed its science goals.

During the cryogenic phase when it was actively cooling itself, the spacecraft operated at a temperature of about -447 degrees Fahrenheit (-266 degrees Celsius), slightly higher than the universe’s temperature, which is about -454 degrees Fahrenheit (-270 degrees Celsius).

The cryogenic phase lasted from 2009 to 2011, until the spacecraft went into hibernation in 2011.

Following the hibernation period, NASA decided to reactivate the WISE spacecraft under the NEOWISE mission, with a more specialized focus on detecting near-Earth objects, which was still feasible even without the cryogenic cooling.

During this reactivation phase, the detectors didn’t need to be quite as sensitive, nor the spacecraft kept as cold as it was during the cryogenic cooling phase, since near-Earth objects are closer than WISE’s faraway targets.

The consequence of losing the active cooling was that two long-wave detectors out of the four on board became so hot that they could no longer function, limiting the craft’s capability.

Nevertheless, NEOWISE used its two operational detectors to continuously monitor both previously and newly detected near-Earth objects in detail.

NEOWISE’s legacy

As of February 2024, NEOWISE had taken more than 1.5 million infrared measurements of about 44,000 different objects in the solar system. These included about 1,600 discoveries of near-Earth objects. NEOWISE also provided detailed size estimates for more than 1,800 near-Earth objects.

Despite the mission’s contributions to science and planetary defense, it was decommissioned in August 2024. The spacecraft eventually started to fall toward Earth’s surface, until it reentered Earth’s atmosphere and burned up on Nov. 1, 2024.

NEOWISE’s contributions to hunting near-Earth objects gave scientists much deeper insights into the asteroids around Earth. It also gave scientists a better idea of what challenges they’ll need to overcome to detect faint objects.

So, did NEOWISE find all the near-Earth objects? The answer is no. Most scientists still believe that there are far more near-Earth objects out there that still need to be identified, particularly smaller ones.

To carry on NEOWISE’s legacy, NASA is planning a mission called NEO Surveyor. NEO Surveyor will be a next-generation space telescope that can study small near-Earth asteroids in more detail, mainly to contribute to NASA’s planetary defense efforts. It will identify hundreds of thousands of near-Earth objects that are as small as about 33 feet (10 meters) across. The spacecraft’s launch is scheduled for 2027.
