Feedback has been astonished—shocked—to discover that a grove of trees in northern Italy was believed to predict a solar eclipse.

You might wonder, “Are you suggesting that some thought trees could genuinely forecast solar eclipses?” Surprisingly, the answer is yes.

The partial solar eclipse occurred on October 25, 2022. Botanists led by Alessandro Chiorerio had previously inserted electrodes into Norwegian spruce trees to monitor their bioelectrical activity. In a report published in April 2025, they claimed that “Trees anticipated the eclipse and synchronized their bioelectrical behavior hours in advance, with older trees showing greater anticipatory behavior due to initial time asymmetry and increased entropy.”

Ultimately, the errors became apparent. A paper published in Trends in Plant Science on February 6th reported this finding, with insights from journalist Matthew Sparks, who should likely receive recognition for his contributions.

Authors Ariel Nowopransky and Hegyi Isak noted that the drop in sunlight during the eclipse was minimal, ensuring the trees had sufficient light. Moreover, such solar eclipses occur every 18 years or so. The oldest trees in the study, around 70 years old, may not have lived long enough to learn patterns, since solar eclipses trace various paths across the Earth’s surface.

Feedback has examined the original study, but it seems unnecessary to delve deeply to debunk it. The team only wired three trees and five stumps. While sample size isn’t everything, it does matter.

The paper also includes a lengthy section on “Theoretical Analysis of Quantum Field Theory.” Yes, the Q word! “A tree is open, thus dissipative. The system continuously exchanges (releases and receives) matter and energy with the environment in various forms.” Aging of the system and the evolution of time (arrow of time) are discussed, although after the first paragraph’s analysis, it felt like we entered a quantum state where we lost interest.

Interestingly, the electrical activity of the trees was synchronized in the 14 hours leading up to the eclipse. How can we explain this? Novoplansky and Isak suggested, “A total of 664 lightning strikes occurred from October 22 to 25, 2022,” including three strikes within 10 kilometers of the site during the 14 hours prior to the eclipse. Perhaps that’s a factor.

Please Don’t Spill It

Continuing our theme of “People inadvertently sending out amusing press releases,” Feedback received great news about tea.

“Recent scientific research indicates that consuming a daily cup of tea can offer heart-healthy benefits, with growing evidence supporting its effects on cholesterol levels, blood pressure, inflammation, and blood clotting.” As regular tea drinkers, Feedback finds this news uplifting—especially for Mrs. Feedback, whose bloodstream is approximately 70% tea.

Who delivered this news? The Tea Advisory Committee of course. Feedback had not previously heard of them, although their website claims they are “supported by the organization” and receive a restricted educational grant from the UK Tea & Infusions Association, the trade association for the UK tea industry. Their purpose is to “provide the media with unbiased information about the health benefits of black tea.”

The final statement of the press release reads: “Previous research has indicated that the ideal amount is four cups of tea daily, yet only a third (35%) of Brits report drinking three to four cups a day. Our challenge, as tea experts and nutritional scientists, is to ensure the public understands the heart health benefits of tea.” Feedback has more details, but we adore espresso.

Universal and Free

In our ongoing quest to identify exemplary and flawed technical abbreviations, Feedback uncovered a fantastic initiative undertaken by researchers at Carnegie Mellon University.

The concept is straightforward. From Legos to Stickle Bricks, a myriad of construction toys exists. However, they often lack interoperability; with few exceptions, you can’t connect parts from different systems.

Golan Levin and Shawn Sims took it upon themselves to create an open-source 3D printable adapter that allows components from various construction systems to be combined. If you own a 3D printer, you can download the design for free and fabricate your own hybrid toy.

It’s quite impressive. The designers explain their goal to enable “radically hybrid constructive play, creating designs previously deemed impossible, ultimately providing more creative opportunities for children” and to deliver “a public service that corporate interests cannot or will not fulfill.”

Feedback believes this kit deserves wide usage. However, we suspect that the name “Free Universal Construction Kit” might limit its appeal to parents somewhat.

How Apple Sparked Legal Confusion in Its Courtroom Victory

Weeks after a federal appellate court mandated that Apple loosen the reins of CEO Tim Cook, his senior associate deliberated on the next steps.

For over ten years, Apple has insisted that apps utilize the App Store payment system, collecting a 30% commission on sales. However, in 2023, the court ruled that apps could bypass Apple’s payment system and allow users to purchase directly. Cook sought clarity on whether Apple could still impose fees on these sales without breaching the court’s directive.

Phil Schiller, responsible for overseeing the App Store, expressed concerns that the revised fees might be unlawful. He supported direct online sales without Apple’s commission. Luca Maestri, the company’s financial head, disagreed, advocating for a 27% commission to safeguard the business.

Ultimately, Cook sided with Maestri, attempting to rationalize this decision. A federal judge criticized the company in a recent ruling, accusing it of fabricating independent economic research to validate its choices and withholding thousands of documents under claims of attorney-client privilege. Furthermore, at least one executive allegedly misled the court.

The judge’s ruling, alongside witness testimonies this year and company documents disclosed Thursday, highlights the extreme measures Apple has taken to maintain every cent accrued from the App Store. Judge Yvonne Gonzalez Rogers, who presided over the initial lawsuit from Epic Games in 2020, could inadvertently impact Apple’s operations and hurt its credibility as scrutiny around the business intensifies.

Additionally, the company faces multiple legal challenges, including an antitrust lawsuit from the Department of Justice, which accuses it of maintaining a monopoly with its iPhone. Class Action Lawsuits from U.S. app developers and regulatory scrutiny from the U.K., Spain, and potentially China.

Mark A. Remley, a professor at Stanford Law, noted, “If you lose credibility with the court, the next judge may be less forgiving.” This situation could prompt future judges to suspect dishonesty during Apple’s subsequent cases.

Google’s corporate dealings have similarly cast a shadow over its legal processes. A recent judge noted in an antitrust case regarding Google’s advertising technology, the company’s attempts to obscure communications raised concerns about its adherence to court mandates.

In response to Judge Gonzalez Rogers’ ruling, Apple plans to appeal, asserting that the findings were “unjust” and deeming delays to the court order necessary. The company declined to provide further comments on this report.

In 2020, Epic, the creator of Fortnite, filed a lawsuit against Apple, alleging antitrust violations related to the mandated use of the App Store payment system. Although Judge Gonzalez Rogers ruled in Apple’s favor, asserting it wasn’t a monopoly, she highlighted that Apple breached California competition laws by requiring developers to use the App Store for software and services.

To comply with the court’s orders, Apple initiated a project termed “Wisconsin.” Two solutions were explored: one that would allow apps to include links for online purchases at designated locations without fees, and another that would require the app to charge a 27% commission for providing those links.

Without commissions and fees, Apple estimated potential losses totaling hundreds of millions, even exceeding a billion dollars. Opting for the 27% fee would minimize their losses.

In a June 2023 meeting, Cook evaluated commission options ranging from 20–27%. He reviewed analyses indicating that with a 27% commission, Apple could potentially lose its payment system while ultimately endorsing a plan that limited where app links for online purchases could be placed.

Consequently, Apple enlisted an economic consultancy to author reports to substantiate these fees, concluding that its developer tools and distribution services exceed 30% of an app’s revenue.

Apple also instituted a warning screen for online purchases. Cook instructed the team to enhance the warning to emphasize Apple’s commitment to privacy and security. “Rather than terminating their relationship with Apple, the company cannot be held accountable for the privacy or security of transactions made online,” he stated.

After introducing the 27% commission in January 2024, Epic brought Apple back to court, arguing it was not complying with the judge’s orders. Judge Gonzalez Rogers summoned both Apple and Epic to court, where Treasury VP Alex Roman testified that the commission had been finalized on January 16, 2024. Executives revealed that the consultancy report influenced the commission fee setting.

Judge Gonzalez Rogers expressed skepticism about Apple’s honesty and demanded documentation regarding their compliance. Apple submitted 89,000 documents, a third of which were marked confidential. The court dismissed these claims as “baseless,” stating Apple pressured them into concealing more than half the documents.

The findings indicated that Rome lied under oath, that the consultancy report was “deceptive,” and that Apple “willfully” ignored the court’s directives, as termed by Judge Gonzalez Rogers. She characterized this as “concealment.”

Her ruling may empower prosecutors, regulators, and judges in similar ongoing cases against Apple across the globe, according to various antitrust professors and lawyers.

When the company attempts to edit or conceal documents, it may draw the attention of prosecutors and judges to strategize against such “tactics to delay litigation,” especially in the Epic Games case. During testimonies, the credibility of Apple executives was called into question as it became apparent the company “conceals the truth.”

In other cases regarding Apple, such as the Department of Justice antitrust lawsuits, Colin Kass, an antitrust attorney for Proskauer Rose, indicated that the process will begin with a firm statement against Apple’s past tactics. “I won’t entertain any games they’ve played before,” he stated.

The company remains cautious regarding both the Justice Department’s lawsuit and its defense, noted Vanderbilt University law professor Rebecca Ho Allensworth, who studies antitrust. Apple previously claimed that green bubbles in messages from Android users were due to safety concerns. However, she suggested such claims may now be viewed skeptically following the recent ruling.

Allensworth remarked that the judges’ opinions could influence App Store practices, leading to enforced resolutions akin to those from the European Union, the U.K., and Spain—to guarantee regulatory and court confidence.

“Apple behaves as though it operates above the law,” she asserted. “This sends a clear message that such behavior is unacceptable.”

Power Outage Sparks Confusion and Reflection on Digital Reliance in Spain

“It was utter chaos,” remarked Inigo, a physician at a hospital in northern Spain.

Since losing power on Monday afternoon, he noted that emergency generators were reserved for critical areas. This meant a lack of access to patient records, disrupted phone connectivity and email, and colleagues unable to carry out their responsibilities, leading to severe communication breakdowns.

Inigo explained that the hospital’s backup generator was intended to keep surgeries ongoing. However, operations had to be cancelled due to the challenges of safely managing orders and moving patients. “This incident made us realize just how reliant we are on technology,” he said.

On that Monday, about 55 million individuals found themselves thrust back into a pre-electric era as significant blackouts swept through Spain, Portugal, and southern France, marking one of the worst outages in recent European memory. Mobile signals vanished, traffic lights failed, supermarkets fell into darkness, digital payment systems froze, and many found themselves stranded away from home as a prolonged power outage occurred.

Last month, EU residents were advised to prepare with 72 hours’ worth of essential supplies, but this blackout underscored the susceptibility many have to widespread disruptions.

After service was restored, the Guardian spoke with individuals reflecting on the incident and its implications for future preparedness and resilience.

For Inigo, despite the disruption feeling like a “total disaster” at the moment, he appreciated in retrospect that there were no physical injuries. “Moving forward, we should invest in more backup generators and fuel to ensure smoother operations,” he suggested.

Initially, Beibei, 41, in Barcelona, found the power cut to be “very thrilling.” However, concern set in when a neighbor knocked on her door with her four-month-old baby, saying, “I know it’s affecting all of Europe.” “I could see the anxiety on her face,” Beibei shared.

She needed to pick up her six-year-old son from school but had to first find food. “In the dimly lit shop, the cashier was turning away customers who couldn’t pay with cash,” explained Beibei, who is a climate activist and has lived in Spain since the pandemic hit. She collected some essentials but anxiously noticed other shoppers with full carts, fearing she wouldn’t have enough.

On her second trip with her neighbor, she found their nearest supermarket had stopped admitting customers. At another store, Beibei faced an alarming situation. “The cashier unloaded items from my basket when I realized I didn’t have enough cash. Just as the last light went out, she announced, ‘I can’t accept any payments now.’

After reuniting with her sons, Beibei expressed a newfound appreciation for everyday conveniences. “I’ve ensured I have cash ready for next time,” she mentioned.

“This experience has shifted my perspective on what truly matters in life—the nourishment we often take for granted, the presence of loved ones, and the ease of cooking and cleaning with modern appliances. I will never overlook these miracles again.”

The outage also led to passengers being trapped in underground subway tunnels and trains, compelling many to walk long distances and remain stationary for hours.

Doug Crave, 60, from Brighton, boarded a train in Madrid at 9:57 a.m. to visit a friend in Barcelona. However, before reaching his destination, the train experienced a shudder. With no mobile signal, the doors remained sealed for nearly two hours until authorities finally arrived to open them and distribute bottled water.

He recounted that a woman experienced a panic attack lasting about six hours. “It felt stifling and humid in the carriage,” he said. Eventually, police led passengers off the train using flashlights at night, escorting them to Barcelona where they boarded a bus that arrived around midnight.

Crave noted that the ordeal prompted him to reconsider the increasing reliance on digital transactions, as many were unable to buy food or water during the outage.

“In every conversation I had in Barcelona regarding hotels, taxis, and restaurants, there was a common concern about the increasing trend of going cashless,” he reported. “All payment systems failed, leaving cash as the only option, yet most people were unprepared, and ATMs were non-functional.”

Katarina, a 24-year-old engineer from Porto, was in her office when the power went out. Upon returning home, she filled containers with water in case her pump stopped working. She tuned into updates via a battery-operated radio she bought after the EU’s emergency advice last month.

“Nobody had any idea of what to do or where to go or how long it would take,” she recalled.

“On one hand, there’s a lot of discourse about how technology has disconnected us, yet yesterday proved that we remain human. People helped one another, stepped outside, and acted as a community once more.”

With her power still out by 5 p.m. on Monday, Katarina took a stroll with her boyfriend. She observed cars halted due to the absence of traffic lights, orderly bus lines, gardens filled with readers, athletes, and families barbecuing, as well as residents chatting with passersby from their doorways.

“It was quite remarkable,” she said. “It really restored my faith in humanity to witness how quickly people banded together and supported each other despite the chaos around us.”
