For the first time, researchers have managed to simulate a fundamental process of cosmic particle acceleration in a laboratory: the first series of discoveries that will transform our understanding of cosmic rays. Now, scientists from the Universities of Birmingham and Chicago have created a tiny, 100-micrometre Fermi accelerator, in which mobile optical potential barriers collide with trapped atoms, in a partial replica of how cosmic particles pick up energy in space. The technique not only replicates cosmic ray behaviour but also sets a new benchmark in quantum acceleration technology.
Lab-Built Fermi Accelerator Using Cold Atoms Validates Cosmic Ray Theory and Advances Quantum Tech
As per findings published in Physical Review Letters, this fully controllable setup demonstrated particle acceleration through the Fermi mechanism first proposed by physicist Enrico Fermi in 1949. Long theorised to underlie cosmic ray generation, the process had never been reliably replicated in a lab. By combining energy gains with particle losses, researchers created energy spectra similar to those observed in space, offering the first direct validation of Bell’s result, a cornerstone of cosmic ray physics.
In Fermi acceleration, ultracold atoms are accelerated to more than 0.5 metres per second using laser-controlled barriers. Dr Amita Deb, a coauthor and researcher at the University of Birmingham, mentioned, ‘Our chimney is more powerful than conventional quantum nano-measurements, which are the best acceleration tools in the world so far, and while its simplicity and small size can be compelling, its lack of a theoretical speed limit is the most attractive feature.’ The ultracold atomic jets could be readily controlled with high precision in the subsequent experiments.
This progress means that, for the first time, complicated astrophysical events like shocks and turbulence can be studied in a laboratory, lead author Dr Vera Guarrera stated. This opens new avenues for high-energy astrophysics and also for applications in quantum wavepacket control and quantum chemistry.
Researchers plan to find out how different behaviour affects energy cutoffs and acceleration rates. A compact Fermi accelerator of this type could be a cornerstone for studies of fundamental physics and also connect to emerging technologies such as atomtronics.

![The Pope’s AI Warning Could Help Workers Seek Religious Exemptions From Using AI
Pope Leo XIV’s recent encyclical on AI could set off a wave of workers seeking religious exemptions from using the tech at work. One software engineer in North Carolina already secured one last month, Business Insider reports. Erin Maus, a Unitarian Universalist, first sought the accommodation in April at the large tech-entertainment company where she works, which she described as progressive. She argued that using AI did not align with her religious beliefs because of environmental and ethical concerns. Maus was granted the exemption in May, before the pope’s AI remarks. “I’m writing my code and reviewing my code by hand, which seems crazy to say,” Maus told Business Insider. “Just two years ago, how else would you do it?”
Maus is unlikely to be the only person seeking a similar accommodation as companies increasingly invest in AI and push, sometimes even mandate, employees to use the technology. In the U.S., the share of employees who say they use AI at least a few times a year at work has nearly doubled from 21% to 40% in 2025, according to Gallup.
Now, the pope’s remarks and official theological document could give some workers a stronger argument. “In the era of artificial intelligence, when human dignity is threatened by new forms of dehumanization, ours is the pressing duty to remain profoundly human,” the pope wrote in his 43,000-word encyclical titled Magnifica Humanitas, published last month. He wrote that AI is dehumanizing society by reducing “the mystery of the person into data and performance” and called on the tech industry to avoid “the idolatry of profit that sacrifices the weak.”
The pope continued that “a slower pace in adopting AI does not mean opposing progress; instead, it is an exercise of responsible care for the human family.” That call for a slower adoption of AI could be enough for some workers to argue they should not be required to use it on the job. “When he’s speaking, he’s speaking as the pontiff—as a religious figure—so he’s raising these human dignity issues as religious issues, theological issues,” Jonathan Segal, an employment attorney and Duane Morris partner, told HR Brew this month. “I think it is inevitable that some employees will rely on this to say…I can’t use AI because it conflicts with a religious belief that I have.” Under Title VII of the Civil Rights Act of 1964, employers are required to make reasonable accommodations for workers whose sincerely held religious beliefs conflict with a work requirement, unless the accommodation creates an undue hardship for the employer.
And it’s not a stretch to think some of these requests could at least get serious consideration. Just a few months ago, Rex Healthcare agreed to pay 0,000 to settle a lawsuit from the U.S. Equal Employment Opportunity Commission accusing the company of unlawfully denying a remote employee’s request to be exempted from its mandatory COVID-19 vaccine policy over religious beliefs. “I think this opens a door—or it’s a little bit of a road map—for employees to raise concerns,” Segal told HR Brew. “What the courts have said—what the EEOC has most definitely said—is that, as the general proposition, we shouldn’t question the legitimacy [of] sincerely held religious beliefs.” #Popes #Warning #Workers #Seek #Religious #ExemptionsAI,Pope Leo XIV,work](https://i1.wp.com/gizmodo.com/app/uploads/2026/05/shutterstock_2666910201-1280x853.jpg?ssl=1 "The Pope’s AI Warning Could Help Workers Seek Religious Exemptions From Using AI
