In an age of deepfakes and post-truth, as artificial intelligence rose and Elon Musk turned Twitter into X, the Merriam-Webster word of the year for 2023 is “authentic.”

Authentic cuisine. Authentic voice. Authentic self. Authenticity as artifice. Lookups for the word are routinely heavy on the dictionary company's site but were boosted to new heights throughout the year, editor at large Peter Sokolowski told The Associated Press in an exclusive interview.

“We see in 2023 a kind of crisis of authenticity,” he said ahead of Monday's announcement of this year's word. “What we realize is that when we question authenticity, we value it even more.”

Sokolowski and his team don't delve into the reasons people head for dictionaries and websites in search of specific words. Rather, they chase the data on lookup spikes and world events that correlate. This time around, there was no particularly huge boost at any given time but a constancy to the increased interest in “authentic.”

This was the year of artificial intelligence, for sure, but also a moment when ChatGPT-maker OpenAI suffered a leadership crisis. Taylor Swift and Prince Harry chased after authenticity in their words and deeds. Musk himself, at February's World Government Summit in Dubai, urged the heads of companies, politicians, ministers and other leaders to “speak authentically” on social media by running their own accounts.

“Can we trust whether a student wrote this paper? Can we trust whether a politician made this statement? We don't always trust what we see anymore,” Sokolowski said. “We sometimes don't believe our own eyes or our own ears. We are now recognizing that authenticity is a performance itself."

Merriam-Webster's entry for “authentic” is busy with meaning.

There is “not false or imitation: real, actual,” as in an authentic cockney accent. There's “true to one's own personality, spirit or character.” There's “worthy of acceptance or belief as conforming to or based on fact.” There is “made or done the same way as an original.” And, perhaps the most telling, there's “conforming to an original so as to reproduce essential features.”

“Authentic” follows 2022’s choice of “gaslighting.” And 2023 marks Merriam-Webster’s 20th anniversary choosing a top word.

The company’s data crunchers filter out evergreen words like “love” and “affect” vs. “effect” that are always high in lookups among the 500,000 words it defines online. This year, the wordsmiths also filtered out numerous five-letter words because Wordle and Quordle players clearly use the company’s site in search of them as they play the daily games, Sokolowski said.

Sokolowski, a lexicologist, and his colleagues have a bevy of runners-up for word of the year that also attracted unusual traffic. They include “X” (lookups spiked in July after Musk's rebranding of Twitter), “EGOT” (there was a boost in February when Viola Davis achieved that rare quadruple-award status with a Grammy) and “Elemental,” the title of a new Pixar film that had lookups jumping in June.

Rounding out the company's top words of 2023, in no particular order:

RIZZ: Slang for “romantic appeal or charm" and seemingly short for charisma. Merriam-Webster added the word to its online dictionary in September and it's been among the top lookups since, Sokolowski said.

KIBBUTZ: There was a massive spike in lookups for “a communal farm or settlement in Israel” after Hamas militants attacked several near the Gaza Strip on Oct. 7. The first kibbutz in Israel was founded circa 1909.

IMPLODE: The June 18 implosion of the Titan submersible on a commercial expedition to explore the Titanic wreckage sent lookups soaring for this word, meaning “to burst inward.” “It was a story that completely occupied the world,” Sokolowski said.

DOPPEL GANGER: Sokolowski calls this “a word lover's word.” Merriam-Webster defines it as a “double,” an “alter ego” or a “ghostly counterpart.” It derives from German folklore. Interest in the word surrounded Naomi Klein's latest book, “Doppelganger: A Trip Into the Mirror World,” released this year. She uses her own experience of often being confused with feminist author and conspiracy theorist Naomi Wolf as a springboard into a broader narrative on the crazy times we're all living in.

CORONATION: King Charles III had one on May 6, sending lookups for the word soaring 15,681% over the year before, Sokolowski said. Merriam-Webster defines it as “the act or occasion of crowning.”

DEEPFAKE: The dictionary company's definition is “an image or recording that has been convincingly altered and manipulated to misrepresent someone as doing or saying something that was not actually done or said.” Interest spiked after Musk’s lawyers in a Tesla lawsuit said he is often the subject of deepfake videos and again after the likeness of Ryan Reynolds appeared in a fake, AI-generated Tesla ad.

DYSTOPIAN: Climate chaos brought on interest in the word. So did books, movies and TV fare intended to entertain. “It's unusual to me to see a word that is used in both contexts,” Sokolowski said.

COVENANT: Lookups for the word meaning “a usually formal, solemn, and binding agreement” swelled on March 27, after a deadly mass shooting at The Covenant School in Nashville, Tennessee. The shooter was a former student killed by police after killing three students and three adults.

Interest also spiked with this year's release of “Guy Ritchie's The Covenant” and Abraham Verghese's long-awaited new novel, “The Covenant of Water,” which Oprah Winfrey chose as a book club pick.

More recently, soon after US Rep. Mike Johnson ascended to House speaker, a 2022 interview with the Louisiana congressman recirculated. He discussed how his teen son was then his “accountability partner” on Covenant Eyes, software that tracks browser history and sends reports to each partner when porn or other potentially objectionable sites are viewed.

INDICT: Former President Donald Trump has been indicted on felony charges in four criminal cases in New York, Florida, Georgia and Washington, D.C., in addition to fighting a lawsuit threatening his real estate empire.

When part of a SpaceX rocket re-entered Earth's atmosphere exactly a year ago, it created a spectacular fireball that streaked across Europe's skies, delighting stargazers and sending a team of scientists rushing towards their instruments.

The German team managed to measure the pollution the rocket's upper stage emitted in our planet's difficult-to-study upper atmosphere -- the first time this has been achieved, according to a study published on Thursday.

It is vital to learn more about this little-understood form of pollution because of the huge number of satellites that are planned to be launched in the coming years, the scientists emphasized.

In the early hours of February 19, 2025, the upper stage of a Falcon 9 rocket was tumbling back to Earth when it exploded into a fireball that made headlines from the UK to Poland.

"We were excited to try and test our equipment and hopefully measure the debris trail," the team led by Robin Wing and Gerd Baumgarten of the Leibniz Institute of Atmospheric Physics in Germany told AFP via email.

In particular, the scientists wanted to measure how the rocket polluted what they call the "ignorosphere" -- because it is so difficult to study.

This region between 50 to 100 kilometers (31 to 62 miles) above Earth includes the mesosphere and part of the lower thermosphere.

- 'Harbinger' -

The team used technology called LIDAR, which measures pollution in the atmosphere by shooting out lots of laser pulses and seeing which bounce back off something.

They detected a sudden spike in the metal lithium in an area nearly 100 kilometers above Earth. This plume had 10 times more lithium than is normal in this part of the atmosphere.

The team then traced the plume back to where the rocket re-entered the atmosphere, west of Ireland.

For the first time, this proves it is possible to study pollution from re-entering rockets at such heights before it disperses, the scientists said.

But the impact from this rocket pollution remains unknown.

"What we do know is that one ton of emissions at 75 kilometers (altitude) is equivalent to 100,000 tons at the surface," they said.

The study warned the case was a "harbinger" of the pollution to come, given how many rockets will be needed to launch all the satellites that Earth is planning to blast into space.

Currently, there are around 14,000 active satellites orbiting our planet.
In the middle of last month, China applied for permission to launch around 200,000 satellites into orbit.

Then at the end of January, billionaire Elon Musk's SpaceX applied for permission to launch one million more.

Eloise Marais, a professor of atmospheric chemistry at University College London not involved in the new study, told AFP the research was "really important".

"There is currently no suitable regulation targeting pollution input into the upper layers of the atmosphere," she explained.

"Even though these portions of the atmosphere are far from us, they have potentially consequential impacts to life on Earth if the pollutants produced are able to affect Earth's climate and deplete ozone in the layer protecting us from harmful UV radiation."

The study was published in the journal Communications Earth & Environment.

For more than a century, biology textbooks have stated that vision among vertebrates - people included - is built from two clearly defined cell types: rods for processing dim light and cones for bright light and color. New research involving deep-sea fish shows this tidy division is, in reality, not so tidy.

Scientists have identified a new type of visual cell in deep-sea fish that blends the shape and form of rods with the molecular machinery and genes of cones. This hybrid type of cell, adapted for sight in gloomy light conditions, was found in larvae of three deep-sea fish species in the Red Sea, Reuters reported.

The species studied were: a hatchetfish, with the scientific name Maurolicus mucronatus; a lightfish, named Vinciguerria mabahiss; and a lanternfish, named Benthosema pterotum. The hatchetfish retained the hybrid cells throughout its life. The other two shifted to the usual rod-cone dichotomy in adulthood.

All three are small, with adults measuring roughly 1-3 inches (3-7 cm) long and the larvae much littler. They inhabit a marine realm of twilight conditions, with sunlight struggling to penetrate into the watery depths.

The vertebrate retina, a sensory membrane at the back of the eye that detects light and converts it into signals to the brain, possesses two main types of light-sensitive visual cells, called photoreceptors. They are named for their shape: rods and cones.

"The rods and cones slowly change position inside the retina when moving between dim and bright conditions, which is why our eyes take time to adjust when we flick on the light switch on our way to the restroom at night," said Lily Fogg, a postdoctoral researcher in marine biology at the University of Helsinki in Finland and lead author of the research published in the journal Science Advances.

"We found that, as larvae, these deep-sea fish mostly use a mix-and-match type of hybrid photoreceptor. These cells look like rods - long, cylindrical and optimized to catch as many light particles - photons - as possible. But they use the molecular machinery of cones, switching on genes usually found only in cones," Fogg said.

The researchers examined the retinas of fish larvae caught at depths from 65 to 650 feet (20 to 200 meters). In the type of dim environment they inhabit, rod and cone cells both are usually engaged in the vertebrate retina, but neither works very well. These fish display an evolutionary remedy.

"Our results challenge the longstanding idea that rods and cones are two fixed, clearly separated cell types. Instead, we show that photoreceptors can blend structural and molecular features in unexpected ways. This suggests that vertebrate visual systems are more flexible and evolutionarily adaptable than previously thought," Fogg said.

"It is a very cool finding that shows that biology does not fit neatly into boxes," said study senior author Fabio Cortesi, a marine biologist and neuroscientist at the University of Queensland in Australia. "I wouldn't be surprised if we find these cells are much more common across all vertebrates, including terrestrial species."

All three species emit bioluminescence using small light-emitting organs on their bodies, mostly located on the belly. They produce blue-green light that blends with the faint background light from the sun above. This strategy, called counterillumination, is a common form of camouflage in the deep sea to avoid predators.

"Small fish like these fuel the open ocean. They are plentiful and serve as food for many larger predatory fishes, including tuna and marlin, marine mammals such as dolphins and whales, and marine birds," Cortesi said.

These kinds of fish also engage in one of the biggest daily migrations in the animal kingdom. They swim near the surface at night to feed in plankton-rich waters, then return to the depths - 650 to 3,280 feet (200 to 1,000 meters) - during daytime to avoid predation.

"The deep sea remains a frontier for human exploration, a mystery box with the potential for significant discoveries," Cortesi said. "We should look after this habitat with the utmost care to make sure future generations can continue to marvel at its wonders."

Osaka has received an unusual donation -- 21 kilograms of gold -- to pay for the maintenance of its ageing water system, the Japanese commercial hub announced Thursday.

The donation worth $3.6 million was made in November by a person who a month earlier had already given $3,300 in cash for the municipal waterworks, Osaka Mayor Hideyuki Yokoyama told a press conference.

"It's an absolutely staggering amount," said Yokoyama, adding that he was lost for words to express his gratitude.

"I was shocked."

The donor wished to remain anonymous, AFP quoted the mayor as saying.

Work to replace water pipes in Osaka, a city of 2.8 million residents, has hit a snag as the actual cost exceeded the planned budget, according to local media.
