480-Million Year Old Chromosomes

Researchers from the University of Oregon have uncovered a groundbreaking discovery in octopus biology: a specific chromosome determines their sex, potentially making it one of the oldest sex-determination systems in the animal kingdom. The California two-spot octopus possesses a unique chromosome that distinguishes sex and may have existed for 480 million years—predating the evolutionary split between octopuses and nautiluses. "This just adds another layer to what we already know about cephalopods," said study author Gabby Coffing. "They have really ancient sex chromosomes."

Until now, cephalopod sex determination remained a mystery, unlike the well-studied systems in mammals and birds. Researchers found that female octopuses have a chromosome containing only half the genetic material of other chromosomes, a feature absent in males. This led them to conclude it functions as a sex chromosome. Further genomic analysis revealed its presence in another octopus species, as well as squids and nautiluses, suggesting cephalopods have used this chromosome for nearly 500 million years with little change—unlike human sex chromosomes, which have evolved significantly over time.

Despite this major breakthrough, scientists are still unsure how octopuses use this chromosome to determine sex. Initial theories suggested a bird-like system, but the absence of a W chromosome points to a different mechanism—possibly with males carrying two Z chromosomes while females have only one. This finding adds to the growing body of knowledge about cephalopods, already renowned for their intelligence and complexity, and provides fresh insights into the evolution of sex determination in the animal kingdom.

A Long Overdue Reunion

After eight years apart, Paul Guilbeault was finally reunited with his beloved dog, Damian. The once-lost pup, now older with wobbly legs and a graying snout, had disappeared in 2017 after slipping out of his leash at an Oklahoma rest stop. Despite days of searching, Guilbeault and his family had to leave without him, a heartbreaking moment that stayed with him for years. Determined to never give up, he continued posting about Damian on lost pet pages, holding onto hope that one day they’d be together again.

That day came in the most unexpected way. A woman in Oklahoma City nearly hit a small brown dog on the road and, after a brief struggle, brought him to a vet, where a microchip scan revealed his identity. At that moment, Guilbeault and his husband were en route to Los Angeles when they received the life-changing notification: "Your dog, Damian, has been found." Without hesitation, they rerouted, driving 16 hours straight for the emotional reunion. Now, making up for lost time, Guilbeault and Damian enjoy daily park visits—this time, with Damian never straying far from his side.

Ghost Stations Rebuilt

Across major U.S. cities, historic rail depots and train stations are finding new life as hotels. Originally built to handle heavy traffic, these stone and brick structures have proven both durable and visually striking, making them prime candidates for restoration. Many of these grand stations, once bustling transit hubs, sat unused for decades, but developers are now recognizing their potential as unique hospitality destinations.

Some of the most notable transformations include Detroit’s Michigan Central Station, which stood abandoned and scavenged for decades before Ford launched a $1 billion redevelopment project to convert it into a multi-use space with parks, offices, and a hotel occupying four floors of its 16-story tower. In Denver, Union Station, once serving 50,000 passengers daily before falling into decline, underwent a $54 million renovation that turned it into a vibrant hub with a luxury hotel, cafes, and shops. By 2024, train traffic there had rebounded to 10,000 passengers per day. Similarly, Salt Lake City’s Union Pacific Depot, which saw rail traffic dwindle before closing in 1997, was repurposed in 2006 as a restaurant and music venue. By 2024, it had fully transformed into the Asher Adams Hotel, offering 225 rooms and serving as a gateway to a bustling commercial district.

Experts argue that restoring these historic stations is not only financially sound but also environmentally sustainable. “Preserving what you have is more cost-effective than demolishing and rebuilding,” said Diana Melichar, president of Melichar Architects. With their solid construction and timeless design, these buildings are poised to stand for another century, proving that the past can be seamlessly integrated into the future.

Mind Stretchers

⁉️ 

I’m cold and crisp or dark and bold,
Found in bottles, cans, or foamed in gold.
I cheer the nights and calm the nerves,
But too much of me throws off your curves.
What am I?
