Why Memory Manipulation Might Be One of Humanity’s Best Innovations

New scientist. Our website and magazine feature science news and long reads by expert journalists covering developments in science, technology, health and the environment.

I vividly remember the moment my late lab partner, Xu Liu, and I first met.
Illuminated, it felt as if the neurons responsible for some of our memories were breathing life into those thoughts again. We stimulated groups of neurons in the hippocampus of mice, positing that these neurons serve as the physical foundation of memories, or engrams. Little did we realize, we were delving into one of neuroscience’s most thrilling frontiers: the potential to modify memories themselves.

The term “memory manipulation” might evoke unsettling imagery of erased histories and deceitful implants. However, within the lab, the reality is much more serene and optimistic. The very discovery that enables us to activate or deactivate memories in mice is also guiding us on how to heal our brains, including methods for diminishing trauma
memory and enhancing the fading
elements, allowing us to rebalance the emotions associated with our memories
we carry.

Over the last decade, this research has unveiled three significant principles. First, memories are adaptable during their storage, recall, and restoration. Second, they are situated across various regions in the brain rather than being localized to one area. Finally, memories can be artificially implanted within the brain. Each principle reshapes our understanding of what “memory editing” signifies.

During memory formation, brain cells collaborate and strengthen their connections. This process can be either enhanced or hindered by varying stimulation patterns. Brain stimulation through implanted electrodes or magnetic pulses can facilitate navigation in a
virtual environment. Substances like medications, hormones, and even tiny amounts of sugar can bolster the brain’s ability to stabilize new experiences. Moreover, exercise promotes the development of new neurons, thereby enhancing the health of the hippocampus and the brain overall
body. Conversely, overstimulation of memory circuits may lead to a decline in memory strength
leading to degradation; inhibiting the molecules that fortify these connections can weaken them further.

Memories can also be altered at the moment of recollection, temporarily rendering them unstable, thus creating opportunities to adjust them before they are stored once more. Therapists are already utilizing this “window of reintegration” in assisting individuals grappling with phobias and trauma. In our studies involving animals, the repeated reactivation of distressing memories is enough to
dull their emotional impact. Additionally, reactivating positive memories during periods of stress can completely overshadow negative emotions. In one
rat study, a week of “positive memory reactivation” alleviated depression-like symptoms for over a month.

Given that memories are distributed throughout the brain, they are highly resilient. Damage to a specific region will likely not erase the entire experience; instead, the brain finds alternative pathways to access memories through
multiple “drafts”. This redundancy provides hope for treating Alzheimer’s disease. If we can reinforce the pathways to the intact memories, we might restore fragments of our identity previously deemed lost. Thus, memory manipulation isn’t about altering who we are; it’s about forging new pathways back to our true selves.

Like any significant medical development, from pacemakers to transplants, this concept raises ethical considerations. Our aim is to alleviate suffering to improve overall well-being. It’s about assisting veterans in easing the grip of flashbacks, aiding individuals in recovery to dissociate cravings from triggers, and helping those with Alzheimer’s to grasp the names of loved ones.

Learning to reshape memories responsibly can foster healing. Each time a memory is revisited, the brain is already in editing mode. Today’s science is just beginning to uncover the rules guiding this process. As I recall fleeting memories with Xu, I envision not science fiction, but a future in which scientific knowledge and memory converge to become foundational to mental health.

Scientists Achieve Breakthroughs in Crystal Bit Manipulation Accuracy

A group of physicists from Oxford University has accomplished the lowest error rate (just 0.000015%, or one error in 6.7 million operations) in quantum logic operations.

“As far as we know, this is the most accurate qubit manipulation ever reported globally,” stated Professor David Lucas from Oxford University.

“This represents a crucial milestone in constructing a practical quantum computer capable of solving real-world problems.”

To conduct meaningful calculations on quantum computers, millions of operations must engage numerous qubits.

Consequently, if the error rate is excessively high, the end result of the computation becomes useless.

Error correction techniques can address mistakes, but they require additional qubits, which come at a cost.

By minimizing errors, new methodologies decrease the number of qubits needed, leading to a reduction in both the cost and size of the quantum computer itself.

“By significantly decreasing the chances of errors, this advancement will greatly lessen the infrastructure necessary for error correction, paving the way for future quantum computers to be smaller, faster, and more efficient,” said Molly Smith, a graduate student at Oxford University.

“Kitz’s precise control is beneficial for other quantum technologies, including timepieces and quantum sensors.”

This groundbreaking accuracy was attained using trapped calcium ions as qubits.

These ions are ideal candidates for storing quantum information due to their longevity and resilience.

Researchers adopted an alternative method, using electron (microwave) signals to manage the quantum states of calcium ions instead of traditional lasers.

This technique is more stable than laser control and offers several advantages for constructing practical quantum computers.

For instance, electronic control is less expensive and more robust than lasers, facilitating easier integration into ion trap chips.

Moreover, the experiment was conducted at room temperature and without magnetic shielding, simplifying the technical necessities of operating quantum computers.

“This record-setting achievement signifies a significant milestone, but it is part of a larger challenge,” the author remarked.

“In quantum computing, both single and two-qubit gates must function together.”

“Currently, the gates of the two-qubit systems still experience a very high error rate, approximately 1 in 2,000 even in the best demonstration to date.

Their paper has been published online in the journal Physical Review Letters.

Elon Musk Imitates Hearst and Ford’s Media Manipulation Tactics

Pioneers in the automotive industry realized they had to transform their worldview, using their influence to acquire media outlets. Their tirades embolden anti-democratic forces globally, tapping into humanity’s darker instincts.

This notion may evoke Elon Musk’s social media platform X in 2025, yet it also harks back to Henry Ford and his publication, the Dearborn Independent, from the 1920s. Ford, who created the Model T, routinely acquired suburban spaces to propagate anti-Semitic narratives. The Dearborn Independent published a notorious series titled “The International Jew,” casting blame on Jewish communities for various societal ailments and disseminating the fabricated “Protocols of the Elders of Zion.” The Nazis even awarded Ford a medal for his fervent beliefs.

Ford epitomizes a longstanding trend of influential figures purchasing media platforms to endorse controversial perspectives. These notable individuals have reached vast audiences through the evolving technology of their times, whether through rapid newspaper distribution or Ford’s extensive network of automobile dealers.

If you take a ride in the latest Model T, you’ll encounter the Dearborn Independent. In the seat. During that era, local newspapers were significant entities. The Dearborn Independent emerged as one of the country’s top-circulating newspapers, reaching over 750,000 copies per issue at its zenith.

Following Henry Ford’s acquisition of the Dearborn Independent, he launched a long-standing series entitled “International Jews.”

Unlike Ford, other media moguls like Rupert Murdoch generally employed like-minded editors and anchors to express their views. The Dearborn Independent boldly announced its title as “Ford International Weekly,” even featuring a full-page editorial signed by Ford himself.

Musk’s behavior mirrors Ford’s personal approach. Tesla and SpaceX’s billionaires have eagerly shared, reposted, and endorsed false or sensational claims on X, such as the assertion that Social Security is fraudulent.

Numerous precedents exist for Musk’s actions with X. However, he has escalated the process to an unprecedented level. The platform claims he has 220 million followers, a staggering number to substantiate. Even if only a fraction of that figure is accurate, X is optimized to amplify user posts as widely as possible, ensuring they are seen and discussed.

In 2022, Musk acquired Twitter for $44 billion, which seemed absurd to many. Initially dismissed as a billionaire’s toy, it transformed into a tool for political leverage during last year’s elections. Musk formed an alliance with Donald J. Trump, using the platform to shut down adversarial voices within the government.

The repercussions are continuously evolving. For Musk, this maneuver represented a significant triumph. Under the guise of enhancing government efficiency, he dismissed regulators poised to oversee his vast empire. Now, Musk wields far more authority over his vehicle and rocket ventures. (X representatives declined to comment.)

Rick Perlstein, author of a comprehensive history of modern American conservatism, stated, “This is something we’ve never encountered before.” Historians note Musk’s frequent use of memes and visuals, observing that “It reflects the politics of the nervous system rather than higher cognitive functions. There’s no rational discourse; it’s simply fear-based.”

Moguls in both the U.S. and Britain have controlled media to wield influence since modern newspapers emerged in the late 19th century. During World War I, Viscount Northcliffe of England dominated about 40% of morning and 45% of evening newspaper circulations. His publications included the Daily Mail, popular among the working class, and The Times, appealing to the elite.

Viscount Northcliffe, also known as Alfred Harmsworth, played a pivotal role in forcing Prime Minister Herbert Asquith to resign in December 1916. His sway was so significant that, in 1917, German forces attempted to assassinate him, shelling coastal residences.

In the U.S., media ownership often exhibited local nuances. In West Texas during the early 1960s, the ultra-conservative Wittenbergs owned the Amarillo Daily News and controlled dominant NBC TV and radio stations, facing little opposition.

Historian Jeff Roche, author of “Conservative Frontier,” noted, “Providing the populace with a far-right media diet can push them towards extreme right-wing views. Amarillo has consequently become America’s most conservative city.”

Simon Potter, a contemporary history professor at the University of Bristol specializing in mass media, remarked, “From the inception of the newspaper industry, media ownership and political influence have been intertwined. Concerns about this close relationship with politics have persisted over time. Does it truly serve the public interest?”

Central to that inquiry is the question: Do these megaphones genuinely empower them, or are they merely shouting into the void? Musk’s American counterpart, William Randolph Hearst, offers insight. Hearst, owner of the New York Journal, dispatched a correspondent to Cuba in 1897 to cover the conflict with Spain, driven less by humanitarian motives and more by then-popularism.

The March 25, 1898 edition of the New York Journal documented Hearst’s war coverage with correspondents in Cuba.

One interpretation of this narrative positions Hearst as a powerful media magnate.

A reporter affiliated with the journal discovered there was no conflict. “Everything is tranquil,” remarked artist Frederick Remington. “There’s no fighting.” They desired to depart.

Hearst retorted: “Depart. You will provide the images; I will provide the war.” This strategy led to his newspaper becoming a significant force amid tumult sparked by President William McKinley, who rapidly escalated tensions, culminating in the liberation of Cuba and acquisition of a vital segment of the Spanish Empire.

This tale, initially told by Hearst’s colleague James Creelman, later resonated in Orson Welles’ Citizen Kane. Though thoroughly debunked, the anecdote persists, illustrating a powerful figure capable of instigating war from nothing.

However, Hearst’s ambitions faltered when he attempted to leverage his wartime momentum to advance his political career. He secured a House of Representatives seat in 1902 but was subsequently defeated in two mayoral bids in New York. His campaign for Governor of New York in 1906 also ended in failure.

David Nasaw, author of “Chief: The Life of William Randolph Hearst,” believes Musk employs X to consolidate support.

“I’ve never seen Twitter as a platform for MAGA supporters anywhere,” he stated.

Nasaw further suggests that Hearst reflected readers’ sentiments rather than shaping them. However, he acknowledged the unique developments occurring with Musk. Hearst, Ford, Viscount Northcliffe before World War II, and even the lords of British media all shared a commonality.

“They were positioned outside the rooms, shouting to be heard,” Nasaw remarked. “Musk’s relationship with Twitter was crucial, but it served as a conduit, enabling his entry into political discourse. This dynamic is unprecedented.”

As Tesla’s sales plummet, both Hearst and Ford could serve as cautionary tales for Musk. Seeking controversy through hateful rhetoric can severely damage one’s reputation and typically harms business.

Ford faced legal action for libel stemming from the Dearborn Independent, leading to a boycott against him. He ultimately shuttered the publication in 1927, though he never renounced his ideology. The remnants of that controversy still echo.

In the 1930s, Hearst confronted President Franklin D. Roosevelt, positioning an anti-Roosevelt manifesto on his publication’s front page. As the editorials grew increasingly harsh, readers were compelled to choose: whom to support, the CEO or the publisher?

“They chose Roosevelt,” Nasaw recalled. “This choice led to Hearst’s ultimate self-destruction and the downfall of his newspaper.”
