Scientists find millions of 'golden eggs' near underwater volcano in Canada. What are they?
"The whole thing is wild," lead researcher Cherisse Du Preez of Fisheries and Oceans Canada told USA TODAY in an email May 20. "It challenges what we consider possible for life on this planet."
The discovery dates back to 2023 but has received rounds of media attention since then. More detailed research findings are set to be published in a Canadian government science report soon, Du Preez said.
The eggs, which come from the Pacific white skate, were found in waters once thought too cold to support life. The Pacific white skate is a "bone-white, bug-eyed relative of sharks that can live almost two miles underwater," according to National Geographic.
"Ours were the first dives on the volcano. No one knew the ancient underwater volcano was active, let alone emitting heat," Du Preez said. "And this geothermally heated hot spot was covered in giant eggs. We think the main nursery is home to 2.6 million golden eggs that take up to 10 years to incubate."
She said the skates choose to lay their eggs on the vents to help with incubation: "The deep sea is cold, and heat helps. To grow big, strong animals, some warmth helps."
The hot, mineral-rich fluid keeps the surrounding waters toasty, providing ideal conditions for some marine creatures to survive in the deep sea, Live Science said.
"As a first, we filmed the female laying eggs. It's out of this world, but at the same time >90% of the livable space on our planet is the deep sea," Du Preez concluded in the email.
Du Preez posted video of the discovery, including a robotic arm lifting one of the eggs, which appeared a vibrant gold color.

‘Eclipse of the century' is coming: Here's where you can see all 6 minutes and 23 seconds of totality
In two years from tonight, all eyes will be on the sky. The 'eclipse of the century' is set to take place on Aug. 2, 2027, according to NASA, with the moon moving between the sun and the Earth for up to 6 minutes and 23 seconds. It will be the longest eclipse totality until the year 2114, USA Today reports. The August 2027 eclipse will be the longest since July 11, 1991, where totality lasted up to 6 minutes and 53 seconds in some locations. SobinSergey – Americans hoping to witness the spectacle will need to make travel plans, as only a partial solar eclipse will be visible in parts of Maine between 5:14 and 5:19 a.m. on that day. For a better look at what is being dubbed 'the natural event of the century,' sky-watchers will have to head overseas. The track of the eclipse is 9,462 miles long and will cross areas including southern Spain, northern Morocco, and northern Algeria. However, the best view will be just outside Luxor, Egypt, which will experience a staggering 6 minutes 23 seconds of totality. That will make the eclipse the longest since July 11, 1991, when totality lasted up to 6 minutes and 53 seconds in some locations. The best view will be just outside Luxor, Egypt, which will experience a staggering 6 minutes 23 seconds of totality. Adil – Those who can't wait two more years for the phenomenon will be pleased to know a shorter solar eclipse will occur next August. That eclipse will occur on Aug. 12, 2026 and will be visible in parts of Greenland, Iceland, Spain, Russia and Portugal, per NASA.

How DNA And Data Are Solving America's Coldest Cases
Across the United States, more than 50,000 people have died without a name. These are individuals who were never identified, never claimed and often never mourned. But thanks to forensic technology and the growing use of genetic genealogy, that's beginning to change. Naming the Dead, a six-part docuseries from National Geographic, brings this invisible crisis to light. The series follows the DNA Doe Project, a nonprofit using cutting-edge DNA analysis and open-source genealogy tools to solve some of the country's most confounding cold cases. It's a quiet revolution in forensics, powered by algorithms, datasets and persistence. From Data to Identity The process of forensic genetic genealogy begins by extracting DNA from unidentified remains. That data is then uploaded to public databases in search of distant relatives. It might sound simple, but it rarely is. Samples are often degraded, especially if they've been buried or exposed to the elements for years. Sequencing has to be precise. And even when a viable DNA profile is produced, the real challenge starts: building family trees from matches that might be third or fourth cousins, or even more distant. I recently spoke with Jennifer Randolph, director of the DNA Doe Project, about the objective of her and her team, and about this Nat Geo series. She described the work as 'a really large logic puzzle.' She added, 'Our genetic genealogy volunteers really like that kind of a challenge... you get pretty excited because it's that feeling of, you know, you're on the cusp of resolving this puzzle.' That excitement is balanced by the gravity of the work. 'It becomes very bittersweet,' she said. 'We know that some family is going to get a knock on the door and they're going to get not the news they hoped for.' It's resolution, not closure—but it's more than many of these families have had in decades. My Experience with Genetic Discovery A few years ago, I submitted a DNA test through It was mostly out of curiosity, but also with the hope of finding a missing uncle—my mother's brother—who was separated from the family while they were in foster care. We only have one photo of him as a toddler, and for most of my life, I've wondered where he ended up. I didn't find him. But I did find someone else. The results revealed that I had a half-brother I never knew existed. We've since connected. We've met. We've had the conversations you never expect to have in your 40s or 50s. The circumstances are complex, but that's the nature of family sometimes. What's important is that the technology gave us a way to discover one another. That experience helped me understand just how powerful this work can be—especially for families of the unidentified dead. It's not just about science. It's about being seen. It's about making the anonymous known. The Tech Making It Possible The show emphasizes how far the technology has come. Advances in next-generation sequencing have made it possible to work with even the most degraded samples—sometimes from cases that are 30 or 40 years old. That data is then uploaded to public databases like GEDmatch, FamilyTreeDNA and DNA Justice. While private services like AncestryDNA and 23andMe hold the largest databases, they don't allow uploads of profiles from unidentified remains. That limitation means the work of the DNA Doe Project depends on much smaller pools of data—typically between 1.5 and 2 million profiles. That makes each match even more critical. Randolph noted the impact of visibility and public education, saying, 'We've had more than one instance where someone learned about [this technique], had a missing person in their family and decided to upload to GEDmatch. And then—out of the blue—a high match, like a niece, appears. And once you have that, you know you're there.' In other words, awareness is its own kind of technology multiplier. Infrastructure for Justice Behind the breakthroughs is a growing ecosystem of cloud-based collaboration. Investigators, coroners, volunteers and data analysts work across states and time zones using shared digital tools. Case notes, DNA files and potential family trees are securely stored and accessed in real time. What used to be the work of entire agencies can now be supported by distributed teams using pro bono platforms. The DNA Doe Project itself operates as a nonprofit, often covering both the cost of lab work and the countless hours of volunteer research it takes to identify a single person. That's one of the reasons this show matters. Visibility attracts donations, but it also sparks interest from law enforcement. As Randolph explained, 'We want every Jane and John Doe to have the opportunity to be identified, no matter who they are or how tough the case might be. So we do try to get the word out at conferences... and then they learn about us through word of mouth.' Beyond the Lab Naming the Dead doesn't glamorize the work. There are dead ends. Cases stall. Some episodes end with possibilities, not certainty. But the emotional core is steady—this is about restoring dignity, not just solving puzzles. And the tech, as powerful as it is, still relies on human effort and intention. None of this happens without people willing to volunteer time, apply pressure and keep showing up for the forgotten. It's worth remembering that some families have waited 20 or 30 years for answers. That kind of silence can be corrosive. When resolution comes—whether through a second cousin match or a last-minute database upload—it opens the door to grief, remembrance and sometimes, healing. Naming the Dead premieres August 2 on National Geographic and streams the next day on Disney+ and Hulu. New episodes run through September 6.

That substance in the water of Great Slave Lake is likely just ash, says DFO
A substance spotted in the water of Great Slave Lake on Thursday is likely "a collection of ash," said Fisheries and Oceans Canada. An "unknown, black substance" near Mosher Island was reported to the Canadian Coast Guard's Arctic Region Marine Environmental and Hazards Response (MEHR) team Thursday morning. MEHR collected samples and submitted them for testing. Based on the evidence, they've confirmed that the curvy black line in the water is ash, likely from a burn barrel "or something of that nature," wrote Jeremy Hennessy, a public affairs officer for the Department of Fisheries and Oceans, in an email. Brian Fidler lives next to Yellowknife Bay and noticed the streak in the water when he was looking out his window. Fidler has lived in Yellowknife for almost five years and said he's never seen anything like it before. "It was a beautiful morning. The water was flat, calm," he said. "I noticed the boats in the little bay there and this weird line that came out seemed to trail from the Yellowknife River direction and kind of curl around." Fidler said it looked like the substance was floating towards Jolliffe Island. While the substance didn't give off the "rainbow kind of fuel" that oil spills are typically characterized with, Fidler said he was still concerned because he didn't know what the slick was. "If more is gonna be coming out into the lake, I don't want to see that. I don't wanna put my boat through it," he said. "If it is chemical or petroleum based, it's not good for the environment. It's not good for our lake." An on-water assessment by MEHR indicated that the substance is not oil-based. There are no impacts to Yellowknife's drinking water and it "is not believed to pose any danger to the public or to wildlife in the area," Hennessy wrote.
