Apple’s record stock performance leads into a discussion of Vision Pro and John Ternus’ explanation of its long-term potential. The MacVoices Live! panel considers spatial computing’s growing role in medicine, productivity, and professional workflows, along with whether the technology is ready for broader adoption. They also examine iPhone battery shipping limits, SoftRAID 9's support of RAID 6, and local versus cloud storage.
Archaeologists rarely identify a settlement from one object. They combine buildings, hearths, tools, food remains, activity areas, and patterns of rebuilding to understand a site.
The MacVoices Live! panel examines Spotify adopting Apple-backed video podcast technology, Instagram’s disappearing posts and why anyone would want them, and Microsoft expanding Copilot everywhere, whether it is a good idea or not. Chuck Joiner, David Ginsburg, Jeff Gamet, Guy Serle, Web Bixby, Eric Bolden, Marty Jencius, and Jim Rea also look at the risks of putting AI mini data centers in homes, and Plex’s major lifetime Pass price hike.
When Plex launched in 2012, it sold lifetime access to its media server software for $75. In 2014, Plex raised the price to be more sustainable for the company, it said, and for years, Lifetime Plex Passes cost $120. Even the pricier $250 rate, which Plex offered from March 2025 until yesterday, was a steal compared to what $250 buys you at Plex now: a five-year subscription.
As first spotted by The Desk, Plex yesterday launched the five-year Plex Pass. It comes alongside Lifetime Pass prices increasing to $750 yesterday, a change that Plex announced in May and, in a blog post update this week, said: “reflects the real, ongoing value of the software and our commitment to building, improving, and supporting Plex for years to come.”
The stark change in what $250 can get you at Plex is indicative of the company’s financial goals. Plex hasn’t yet announced profitability and has raised $87.6 million over nine rounds of funding, per CB Insights. The company is looking to squeeze more money out of its users and price its media server business higher.
A groundbreaking study unveils how the ARP2/3 complex orchestrates the dynamic behavior of neurites, providing fresh insights into neuronal growth and polarity. Researchers utilized advanced optogenetic tools to manipulate RAC1, an upstream regulator of ARP2/3, revealing spatially distinct roles of actin assembly in neuronal morphology.
By employing photoactivatable RAC1 (PA-RAC1), the team demonstrated that ARP2/3-mediated actin assembly at neurite tips promotes growth cone activation and neurite extension. Local activation of PA-RAC1 triggered robust growth cone dynamics, driving neurite elongation. Conversely, activation of a dominant-negative RAC1 mutant led to collapse of the growth cone and neurite retraction, underscoring ARP2/3’s role in sustaining neurite advancement.
Intriguingly, PA-RAC1 activation at the soma induced lamellipodia formation reminiscent of nascent actin waves, which were associated with neurite retraction events. This phenomenon mirrored intrinsic cellular behaviors where somatic actin waves correspond with retracting neurites. The study elegantly showed that the emergence of these waves reduced somatic actin patch intensity, indicating a tightly regulated cytoskeletal oscillator mechanism.
The authors further explored the effects of ARP2/3 inhibition using CK-666 perfusion at distinct cellular locales. When applied over the soma and proximal neurites, CK-666 induced neurite retraction, whereas neurites outside this region continued growing unabated. Notably, actin waves were initiated in neurites outside the inhibited zone, propagating retrogradely toward the soma but dissipating upon entering CK-666-exposed areas. This highlights a spatial dependence of ARP2/3 activity for wave initiation and propagation.
Remarkably, simultaneous activation of PA-RAC1 at multiple growth cones revealed competitive dynamics in actin assembly, with enhanced growth cone activity limited to one or two sites. This suggests an intrinsic cellular mechanism balancing cytoskeletal resources and neurite growth across the complex neuronal arborization.
Together, these findings articulate a dual role for ARP2/3: driving actin wave initiation at the soma that triggers neurite retraction, and supporting growth cone expansion at neurite tips to promote extension. This oscillatory interplay mediated by ARP2/3 and RAC1 underscores the cytoskeleton’s fundamental role in establishing neuronal polarity.
This study not only provides a mechanistic framework for how neurons spatially regulate growth and retraction but also suggests that intrinsic cytoskeletal oscillators underpin the dynamic remodeling necessary for proper neuronal circuit formation. These insights pave the way for future investigations into cytoskeletal dysregulation in neurodevelopmental disorders and neuronal regeneration strategies.
The precise spatial control of actin dynamics mediated by ARP2/3 complex activity advances our understanding of neuronal development, highlighting how local cytoskeletal modulators can dictate overall neuronal architecture through oscillatory growth behaviors.

The word Rolex has five letters, two syllables, and works in every language a marketer might want to sell into. It is short enough to sit on a watch dial without crowding the hands, blunt enough to pronounce in German, French, Japanese, and Hindi without distortion, and abstract enough to mean nothing at all. A young Bavarian named Hans Wilsdorf registered it as a trademark in 1908 in La Chaux-de-Fonds, Switzerland, years before he had a factory of his own. The name came first. The watches followed.
That sequence — invent the word, secure the word, then build the company around it — is one of the earliest known examples of what marketers would later call a coined brand. Wilsdorf did it in 1908 for a product he did not yet manufacture.
Wilsdorf had ended up in London after a stint at a watch exporter in La Chaux-de-Fonds. By his mid-twenties he was importing Swiss movements and casing them in England under the unglamorous name Wilsdorf & Davis. He wanted something better. He wanted a name that was short, memorable, pronounceable in any European tongue, and small enough to be legible above the 12 o’clock marker of a wristwatch barely 30 millimetres across.
The constraints were real.
Try the test yourself. Write your favourite watch brand on a dial 30 millimetres wide, leaving room for hour markers, a logo, and the hands. Patek Philippe is thirteen letters and a space. Vacheron Constantin is eighteen. Jaeger-LeCoultre is fifteen and a hyphen. Rolex is five. On a wrist seen from across a room, five wins.
The phonetics of a global product
The cleverness sits in what the word avoids. There is no diphthong that collapses in Mandarin. No silent letter that an English speaker would mispronounce in French. No umlaut. No accent. No consonant cluster that trips an Italian tongue. The two syllables — ro and lex — are phonemes that exist in nearly every major language. A Tokyo retailer and a Geneva concierge say the word almost identically.
This was not accidental. By his own account, Wilsdorf wanted a name that was short, easy to say and remember in any language, and that looked good on a dial — a goal he later described as the reason he ran through hundreds of letter combinations before settling on Rolex, as Rolex itself recounts in its company history. He had also learned, selling watches across the British Empire and into continental Europe, that brand names with national flavour travelled badly.
He got one. Rolex is the closest thing the watch industry has ever produced to a piece of linguistic infrastructure — a sequence of sounds engineered to survive translation.
Trademark first, factory later
Wilsdorf registered the name in Switzerland in 1908 — the surviving registry entry is dated 2 July 1908 and lists the La Chaux-de-Fonds office of Wilsdorf & Davis, as the original trademark record reproduced in horological archives shows. He was still operating out of London and still casing movements supplied by Hermann Aegler’s workshop in Bienne. He did not own a Swiss manufacturing operation. He owned a word, an import-export business, and a hunch that wristwatches — at that point still dismissed as women’s jewellery, a prejudice Space Daily has explored in detail — would become the dominant form of timekeeping for men within a generation.
He was right on both counts. The First World War, with its trench officers needing both hands free, did for the wristwatch what no advertising campaign could. By 1919 Wilsdorf had relocated to Geneva, partly because British post-war duties made exporting from London punishing, and partly because anti-German sentiment in Britain had already pushed him to rename the firm The Rolex Watch Co. Ltd. in 1915, a change Britannica attributes to wartime prejudice against the German-sounding Wilsdorf name. The company that became synonymous with Swissness was Swiss almost by accident of geopolitics.
What a name buys you
Coining a word does something specific that descriptive names cannot. A descriptive name — Universal Geneve, International Watch Company — tells you what the thing is and where it comes from, and that’s the ceiling of its meaning. A coined word is an empty vessel. Whatever you pour into it over decades of advertising, sponsorship, and product, the word holds.
Wilsdorf began pouring almost immediately. The company developed the Oyster case, among the first commercially viable waterproof wristwatches. In 1927 a young London typist named Mercedes Gleitze, the first British woman to swim the English Channel, wore an Oyster during a high-profile Channel swim, and Wilsdorf took out prominent newspaper advertising to promote it. The word Rolex had its first myth.
The dress watch market is still organised around names of this kind. A 2025 Esquire review of a dress watch describes the category in language Wilsdorf would have recognised: thinness, legibility, restraint. The dials of the watches sitting next to it in auction catalogues all carry short, abstract words. Omega. Cartier. Tudor. Seiko. The naming convention Wilsdorf arrived at in 1908 became the default the rest of the industry now follows.
The decision that made Rolex unbuyable
Naming was the first of two structural decisions that made Rolex what it is. The second came after the death of Wilsdorf’s wife, Florence. Childless and grieving, he created the Hans Wilsdorf Foundation and, in his will, left every share of Rolex to it. When he died in 1960, the foundation became the sole owner. That arrangement — which Space Daily has covered separately — means no shareholder can demand a dividend, no rival can buy the company, and no quarterly report has to be filed. Rolex’s finances remain opaque because there is no legal obligation to publish them.
The opacity is the point. Because the company discloses nothing, every revenue figure is an outside estimate: analysts at Morgan Stanley and LuxeConsult put Rolex’s annual wholesale revenue above CHF 11 billion in their most recent reading, while cautioning that the brand publishes no official figures of its own. The foundation, a registered Swiss charitable trust, directs funds to charitable causes, including children’s charities — a nod to Wilsdorf’s own childhood as an orphan.
In 2023, Rolex agreed to buy Bucherer, its largest retailer, consolidating a distribution partner it had worked with for a century. A privately held watchmaker had moved to absorb its own biggest distributor, the kind of step no public company answerable to shareholders would have executed so quietly.
The freedom to make moves like that traces back to two decisions taken decades apart by the same man. First, in 1908, to coin a word with no national origin and trademark it before he had a factory. Second, decades later, to put the company beyond ownership. The first decision gave Rolex a name that could be sold anywhere. The second made sure no one could ever sell Rolex.
What five letters still do on a dial
Pick up a Submariner. The word sits above the centre pinion in a sans-serif crown-logo lockup that has barely changed in eighty years. Five letters. About four millimetres wide on a 40 mm dial. The eye reads it before it registers the hour. On a black bezel diving watch under a cocktail-bar lamp, the word is legible at three metres. On a gold Day-Date across a boardroom table, it’s legible at five.
That legibility is a function of letter count. Six letters would have required a smaller font. Eight would have required either a smaller font or a curved arc that distorts the reading angle. Five fits the optical sweet spot of a wristwatch dial almost perfectly — the horological equivalent of a logo built for a smartphone home screen, except Wilsdorf made the choice in 1908, when the dominant timepiece was still a pocket watch on a chain.
There is a reason the watch industry has not produced another Rolex-style word in the 118 years since. Most of the obvious five-letter, language-neutral combinations were registered long ago. The rest sound like pharmaceuticals. Coining a word that means nothing and survives a century of meaning being poured into it is harder than it looks, and the field is crowded with failures whose names you have already forgotten.
The trademark filing in La Chaux-de-Fonds in 1908 predated the existence of Rolex SA as an independent Swiss manufacturer by years. It predated the Oyster case by nearly two decades. It predated the foundation that owns the company today by several decades. It predated the watch on the wrist of an English Channel swimmer by nearly twenty years. For most of its first decade, the word Rolex sat on watches whose movements were made by other people, in cases assembled by other people, sold under a name that belonged to a young Bavarian importer in a rented London office. The word did the work. The factory caught up later.
Look at a Rolex dial today and you are reading a piece of linguistic engineering that is older than the Russian Revolution, older than the Model T, older than the first transatlantic flight. The hands have moved roughly a billion times around it. The word has not.
NASA officials have completed an investigation into an incident that caused damage to a 70-meter radio frequency antenna last year.
The incident, which occurred at the Goldstone Deep Space Communications Complex near Barstow, California, affected the space agency’s Deep Space Station 14 (DSS-14), a 70-meter radio-frequency antenna, which currently remains offline awaiting repairs and system upgrades.
Joel Montalbano, acting associate administrator for NASA’s Space Operations Mission Directorate, emphasized that the agency “takes safety and any departure from established procedures seriously,” adding that investigations into the incident at Goldstone “made clear that we must strengthen our processes. We are acting on the investigation’s findings.”
Incident at Goldstone
The damage was caused last September 16, 2025, when the antenna reportedly over-extended during rotation during tracking for NASA’s Juno mission. Stress on the antenna’s cabling and support infrastructure, as well as damage to its fire-suppression system, is expected to cost between $4.1 and $4.6 million in repairs.
Fortunately, no injuries were reported at the time of the incident, and a Mishap Investigation Board was convened to investigate the underlying causes. Following on-site inspections, interviews, and reviews of technical documentation from NASA’s three Deep Space Network facilities, the results of the investigation were included in a report submitted in April, which also made recommendations on how to prevent future incidents.
Software Issues
A primary factor behind the incident had been what the reports’ authors characterize as “software weaknesses, human error, and an undetected failure in the antenna’s hydraulic limit system,” according to a recent NASA statement.
“Investigators determined an electrical issue at the antenna the previous day caused the control system to misreport the antenna’s rotation state, an issue that went unnoticed and triggered multiple limit-stops during the Juno track,” the statement added.
Over-rotation of the antenna resulted after flooding in the antenna base was spotted by operators, following troubleshooting efforts that accidentally bypassed safeguards in the system’s hardware and software.
Investigators also determined that the antenna’s hydraulic limit system had already been rendered inoperable before the September 16 incident, following damage sustained “in an undocumented prior incident.”
Modernization for Future Missions
On June 5, Montalbano emphasized that NASA plans to follow the guidance in the review board’s report, with a focus on ensuring greater adherence to procedures to help limit the likelihood of future mishaps.
“We will update and improve procedures, rebuild core in-house capabilities, and reinforce operational discipline across the Deep Space Network,” Montalbano said.
“NASA remains focused on learning from this and modernizing systems, so DSS-14 and the broader network are ready to support our ambitious future missions,” he added.

Plex is adding new social features to the platform.
As of today, users can make and share "personalized lists on Plex of any movie, show or episode," the company said in an announcement. Later this year, users will be able to import lists from other streaming services and react to other people's lists.
This month, Plex will also launch a community forum that will allow people to "post and comment directly on any movie, show, season, or episode." Later this year, Plex will introduce "Match Scores" based on a viewer's history and past ratings to predict how much they'll like a show or movie, Plex said.
Tom Akers and Joe Tanner are finally in the same class.
The two veteran space shuttle crew members were inducted into the US Astronaut Hall of Fame together on May 16. They could also have been in the same NASA astronaut selection group, too, had history played out a little differently.
In 1984, Tanner reported to the Johnson Space Center (JSC) to fly as an instructor pilot and then applied for the next class of astronaut candidates.
As of July 1, at 12:01 am UTC—or June 30 at 8:01 pm ET—people seeking access to Plex's media server features through a one-time purchase will have to pay $750. That’s three times the current price of $250.
The new price will not affect current Lifetime Plex Pass holders.
A Lifetime Plex Pass allows you to stream from your own Plex Media Server to a device connected to your own network, to stream from the server remotely, and to allow others to stream remotely from your server.
