After decades of pursuit, a significant breakthrough in chemistry has been achieved: scientists have successfully synthesized a stable aromatic ring composed entirely of silicon. This achievement, long considered a theoretical possibility, opens new avenues for materials science and catalyst development, potentially leading to compounds with unprecedented properties. The creation of this silicon-based aromatic structure represents a fundamental advancement in organosilicon chemistry, challenging conventional understanding of molecular stability.

The elusive pentasilacyclopentadienide, an all-silicon analog of the well-known cyclopentadienide, has been a target for researchers for nearly half a century. Silicon’s inherent properties – a larger atomic radius and differing electron affinity compared to carbon – have historically made forming stable, planar aromatic rings incredibly difficult. This new synthesis overcomes those hurdles, paving the way for exploration of silicon-based compounds that mimic the stability and reactivity of their carbon counterparts. The research, published in Science, details the successful creation of this novel molecule, marking a pivotal moment in the field.

Two independent research teams, led by David Scheschkewitz at Saarland University and Takeaki Iwamoto at Tohoku University, simultaneously achieved this breakthrough, utilizing different synthetic strategies but arriving at the same pentasilacyclopentadienide structure. Both teams employed bulky 2,4,6-triisopropylphenyl groups attached to each silicon atom, stabilized by a lithium counterion. “This is one of my dream compounds—the idea of this was with me through my entire independent career and even earlier than that,” stated Scheschkewitz, reflecting the long-standing ambition behind the project. Saarland University researchers have effectively replaced carbon atoms in an aromatic compound with silicon atoms.

Aromatic compounds, renowned for their exceptional stability due to delocalized electrons within their ring structures, are fundamental to chemistry. Benzene and cyclopentadienide are classic examples, adhering to Hückel’s rule, which dictates that planar cyclic molecules with (4n + 2) π electrons exhibit aromaticity. Though, replicating this aromaticity with silicon has proven exceptionally challenging. Previous successes were limited to smaller ring systems, such as the silicon analogue of cyclopropenium synthesized in 1981. Researchers detail that the synthesized compounds feature nonplanar five-membered silicon rings with some pyramidalized silicon atoms and uneven silicon-silicon distances.

The implications of this discovery extend beyond fundamental chemistry. Silicon’s metallic nature, differing from carbon’s, suggests the potential for creating new catalysts and materials with unique properties. As Scheschkewitz explained, “In polyethylene and polypropylene production, for example, aromatic compounds support make the catalysts that control these industrial chemical processes more durable and more effective.” The ability to manipulate the electronic properties of these silicon-based aromatics could lead to advancements in various industrial applications. The breakthrough could unlock access to new compounds and catalysts with particularly different properties.

The synthesis wasn’t without its challenges. Scheschkewitz noted that numerous graduate students in his lab spent the past 20 years attempting to synthesize the structure, with all previous efforts failing. The independent success of both his team and Iwamoto’s highlights the dedication and persistence required to overcome the inherent difficulties in working with silicon-based aromatic systems. Two groups working independently constructed the same long-sought compound via different routes.

Looking ahead, researchers will focus on exploring the reactivity and potential applications of pentasilacyclopentadienide and related silicon-based aromatic compounds. Further investigation into the properties of these molecules could unlock new possibilities in materials science, catalysis, and beyond. The successful synthesis of this long-sought structure marks not an end, but a beginning – a new chapter in the exploration of silicon chemistry and its potential to revolutionize various fields.

A unique act of respect – or perhaps superstition – led to an extraordinary fishing experience for one angler. A fisherman, believing in a bit of luck and tradition, “paid” a lake, and was subsequently rewarded with an impressive haul of pike, culminating in a particularly large catch. The story, originating in the United Kingdom, highlights the enduring connection between anglers and the waters they fish, and the often-unconventional beliefs that accompany the sport.

The angler, identified only as Tom Flower, was fishing with his brother John at a reservoir with the intention of catching pike. Flower, described as a superstitious fisherman, decided to offer a penny to the lake, stating, “We’d pay the lake,” according to a report from Angling Times. This seemingly small gesture preceded a remarkably successful fishing trip, raising questions about luck, tradition, and the psychological impact of ritual on performance.

Within hours of the offering, Flower landed seven large pike, with the largest weighing 26 pounds and 10 ounces (12.08 kg) according to InRybar.cz. The following day brought continued success, with more pike adding to his impressive catch. His brother, however, experienced no such luck, making the experience even more striking.

This unusual event isn’t isolated. In February 2026, InRybar.cz also reported on another instance of an angler believing in a reciprocal relationship with a body of water, though the details of that story remain less specific. The site frequently covers fishing news and techniques, serving as a central hub for anglers in the Czech Republic and Slovakia as detailed on InRybar.cz.

The story echoes a broader sentiment within the fishing community, where rituals and superstitions are common. Whether it’s a lucky lure, a specific hat, or a pre-fishing routine, many anglers believe in practices that enhance their chances of success. Although the scientific basis for such beliefs is absent, the psychological benefits – increased confidence and focus – are well-documented.

Beyond the UK, the pursuit of impressive catches draws anglers to locations renowned for their size and beauty. Lake Bled in Slovenia, for example, has become a popular destination, recently witnessing a remarkable feat: Czech angler Aleš Mezek landed a 33.1 kg (73.0 lbs) carp using a fly fishing rod in July 2025 as reported by InRybar.cz. This catch, considered exceptional even among experienced anglers, underscores the potential for extraordinary experiences in these idyllic settings.

The incident also highlights the growing online community surrounding fishing. Platforms like Facebook, with groups such as “Rybářina CZ/SK,” facilitate the sharing of stories, tips, and experiences among anglers as seen on Facebook. These online spaces contribute to the preservation of fishing traditions and the dissemination of knowledge.

As anglers continue to seek out both impressive catches and a deeper connection with nature, the interplay between tradition, superstition, and skill will undoubtedly remain a captivating aspect of the sport. The story of Tom Flower serves as a reminder that sometimes, a little bit of faith – and a penny – can go a long way.

Verizon is walking back a recent change to its phone unlocking policy that sparked frustration among customers. The company initially implemented a 35-day hold on unlocking devices for customers who used gift cards or other non-traditional payment methods, but now says it will soon drop that requirement for online payments. The shift comes after reports highlighted the confusing rollout and the policy’s impact on consumers seeking to switch carriers or travel internationally.

The issue centers around Verizon’s ability to lock smartphones, preventing them from being used on other networks. While carriers often lock phones to prevent fraud and ensure contract obligations are met, the length of that lock has become a point of contention. Verizon had previously been considered more consumer-friendly unlocking phones after 60 days, a standard influenced by conditions related to spectrum licenses and the acquisition of TracFone. However, the company began seeking waivers from the Federal Communications Commission (FCC) to extend those lock periods.

In 2019, Verizon secured a waiver allowing it to lock phones for 60 days to combat fraud. The company argued that even this timeframe wasn’t sufficient, and last month received another waiver lifting the unlocking requirement altogether, paving the way for the recent policy changes. The rollout, however, proved problematic. Initially, the 35-day delay only applied to purchases made with Verizon gift cards, but the language on the policy page was later broadened, leading to confusion about when the delay would be applied. Verizon stated that the full terms were in effect since January 27, even though the webpage didn’t fully reflect those terms.

FCC Scrutiny and Verizon’s Response

The FCC is now actively seeking feedback from Verizon customers regarding the January blackout and the new unlocking policies. The agency is encouraging frustrated customers to report their experiences, signaling increased regulatory scrutiny of the carrier’s practices. Android Authority reported on the FCC’s call for customer feedback, highlighting the agency’s concern over potential consumer harm.

According to a statement reported by Android Police, Verizon will implement an additional authentication layer for credit card payments online. This added security measure, expected within weeks, will exempt device payoffs from the 35-day hold. A Verizon spokesperson reportedly said the change is intended to streamline the unlocking process for customers using standard payment methods.

A History of Unlocking Policies

Until recently, Verizon distinguished itself among major US carriers with a relatively consumer-friendly unlocking policy. This was largely due to stipulations tied to its 700 MHz spectrum licenses and conditions related to its acquisition of TracFone, which mandated unlocking phones after 60 days. The company’s shift towards longer lock periods began in 2019 with the FCC waiver allowing a 60-day lock to deter fraud. Verizon subsequently argued that even 60 days wasn’t enough, leading to the more recent waiver request.

The current situation underscores the ongoing tension between carriers’ efforts to combat fraud and consumers’ desire for flexibility and control over their devices. The initial rollout of the revised policy was particularly confusing, with changes to the online policy language not immediately reflected in customer communications. This lack of clarity contributed to the negative reaction and prompted the FCC’s intervention.

Verizon’s decision to address the concerns regarding online payments represents a step towards resolving the issue, but the long-term impact of the policy changes remains to be seen. The FCC’s continued monitoring and customer feedback will likely play a crucial role in shaping future regulations and industry practices surrounding phone unlocking. The Supreme Court will too be weighing in on the constitutionality of FCC fines levied against Verizon and AT&T, as reported by Android Authority, adding another layer of complexity to the regulatory landscape.

As Verizon implements the changes to its online payment authentication, customers should monitor their accounts and report any discrepancies or issues. The company’s response to customer feedback and the FCC’s ongoing oversight will be key indicators of whether the new policy strikes a balance between security and consumer convenience.
