How preserved blood vessels found in Saskatchewan's most famous T. rex is opening doors for researchers
'Scotty' is the largest dinosaur skeleton ever found in Canada. (Tourism Saskatchewan) Preserved blood vessel structures discovered in Saskatchewan's most famous Tyrannosaurus rex fossil has opened doors for researchers when it comes to learning how extinct animals healed from injuries. The preserved blood vessel structures were discovered in a rib bone from Scotty the famous T. rex, who was found in Saskatchewan in the 1990s. Jerrit L. Mitchell, a PhD student in the University of Regina's (U of R) Department of Physics and the study's lead author, discovered the vessel structures while finishing his undergraduate honours thesis research. Mitchell joined the ongoing research project in 2019 when Scotty's rib was scanned at the Canadian Light Source at the University of Saskatchewan for the first time. 'I remember showing my supervisors, Dr. Barbi and Dr. McKellar, a strange structure inside a scan of the rib that I originally didn't give much thought to. They were quick to point out that what I discovered could possibly be preserved blood vessels, which has since led to a much more expansive research project,' Mitchell said in a news release. Synchrotron X-rays produced by the Canadian Light Source at the University of Saskatchewan gave researchers the opportunity to create a detailed 3D model of both the bone and soft tissue structures inside it without damaging the 66-million-year-old fossil, the release said. 3D printed blood vessel structures 3D printed blood vessel structures. (Canadian Light Source, University of Regina) 'Then, using chemical analysis, the researchers determined what elements and molecules make up the vessel structures, allowing them to hypothesize how the structures were preserved over millions of years.' The X-rays of the fossil's rib also showed a healed fracture that could have been sustained in a fight, according to researchers.

(Canadian Light Source, University of Regina) 'The discovery could provide important, evolutionary information to researchers, such as the healing potential of a T. rex,' the release said. 'Preserved blood vessel structures, like we have found in Scotty's rib bone, appear linked to areas where the bone was healing. This is because during the healing process, those areas had increased blood flow to them,' physics professor Mauricio Barbi said in the release. 'This work also provides a new way to compare how injuries healed in extinct animals, like dinosaurs,' Barbi added. The findings were recently published in Scientific Reports, an open-access journal that publishes original research from across natural sciences, psychology, medicine and engineering. The U of R says the multidisciplinary study grew to involve researchers from the school's departments of physics, biology, and earth sciences, along with the Royal Saskatchewan Museum (RSM). RSM curator of palaeontology and adjunct professor at the U of R Ryan McKellar said the discovery proves how fossils like Scotty are much more than museum exhibits. 'They continue to advance science in ways we never imagined when they were first unearthed,' he said. 'Part of our role at the Royal Saskatchewan Museum is to ensure these specimens remain available for research, so it's exciting to see new technology and collaborations between the RSM, the University of Regina, and the Canadian Light Source revealing discoveries, while keeping the fossils intact for future generations,' McKellar said.

Rocket Lab Stock Soars Higher as Neutron's Maiden Flight Nears
Rocket Lab Corp. RKLB is currently on the cusp of a transformative milestone with its highly anticipated Neutron rocket approaching its maiden flight in the second half of 2025. To expand beyond its small-launcher Electron and capture the medium-lift payload market, while positioning itself to compete with heavy-lift providers like SpaceX, Rocket Lab launched the Neutron program. This medium-class, reusable vehicle, with a potential payload capacity of approximately 15,000 kg, aims to offer flexible, cost-effective access to space for a wide range of customers, including satellite constellations, government missions, and commercial payloads. To this end, it is imperative to mention that in May 2025 Rocket Lab announced that it will launch its Neutron rocket for the U.S. Air Force Research Laboratory for a Rocket Cargo mission to support point-to-point cargo transportation, establishing a new era of commercial launch capability to advance global defense logistics for the nation. Earlier in February, the company revealed details about the ocean landing platform, a modified barge, for Neutron missions returning to Earth. Customized modification is currently ongoing on this barge, including autonomous ground support equipment to capture and secure the landed Neutron, blast shielding to protect equipment during Neutron landings, and station-keeping thrusters for precise positioning. These announcements implying consistent progress in the Neutron program have bolstered investor confidence, reflected in Rocket Lab's share price performance. While the company's year-to-date price increase has been modest, the past three months have seen a sharper uptick, underscoring growing optimism around Neutron's prospects as new milestones mentioned above are achieved. RKLB's shares gained 40% year to date, while the same soared 103.6% over the past three months. Other Stocks One Should Keep an Eye on The space launch services market has been witnessing solid growth trends driven by surging demand for satellite constellations, increasing government and defense investments, and the growing need for low-cost, reliable access to space to support telecommunications, Earth observation, and national security missions. Therefore, investors interested in this business realm may keep RKLB along with other industry players like Boeing BA and Lockheed Martin LMT in their watchlist, which already enjoy an established footprint in the space launch market. Boeing's products have powered human space exploration for six decades now. The company is the prime contractor for the design, development and production of the core stage, upper stages and flight avionics suite used in NASA's Space Launch System, the only proven deep-space optimized, super-heavy lift rocket built to carry astronauts and cargo farther and faster than any rocket in history. Lockheed Martin is another space stock that has contributed significantly to various space missions with its breakthrough technologies. It is the prime contractor involved in the construction of Orion, the spacecraft that will carry the crew of four astronauts in the Artemis II lunar mission. The Zacks Rundown for RKLB Shares of RKLB have gained 630.8% in the past year compared with the industry 's 50.9% growth. With respect to valuation, the company trades at a premium.

Photography brings threats to oceans into focus
The world's oceans are critical to human life, and they are under threat from the effects of climate change. Award-winning photographers Shane Gross and Cristina Mittermeier are using their images to aid global marine and freshwater ecosystem conservation efforts, and to bring public attention to the importance of our oceans. Gross, a co-founder of the Canadian Conservation Photographers Collective, and Mittermeier, who is also a trained marine biologist, joined journalists Jenn Thornhill Verma and Ryan MacDonald in a pair of conversations at a Globe and Mail event in Toronto on June 24, in partnership with Rolex. They discussed the power of photography to spur change, responses to some of the best-known images, and current areas of focus. Questions and answers have been edited for length and clarity. Jenn Thornhill Verma: You've experienced the ocean from so many different places. What commonalities do you see from behind the camera? Shane Gross: The creatures and the currents don't care about our borders. One example is humpback whales: they'll migrate from Antarctica to French Polynesia. We need to do what we can to make sure that we are protecting not just what's in our waters but beyond that. A big topic of discussion today is the global oceans treaty. Beyond countries' (boundaries) there is still a lot of ocean, and right now it's completely lawless. The global ocean treaty is a United Nations event that hopefully will put some rules in place for that because we desperately need it. JTV: Your seahorse photo is a prime example of how bringing people to an environment they otherwise would not have the opportunity to experience can lend itself to pushing a policy envelope. Talk to us about that image. SG: The place in the photo is Seahorse National Park in the Bahamas. When I first started snorkelling there, we didn't even know what species of seahorses were there. I met with a scientist, Dr. Heather Masonjones, in 2016, and she went and counted how many seahorses were in there. In this pond that's a kilometre-and-a-half by a kilometre, she counted 800,000 seahorses. At the time there was a proposal to turn it into a marina, and also people taking seahorses to sell for the aquarium trade. We teamed up with conservation organizations to get this place protected. We gave talks at schools and used my photo to show the kids, we held community meetings, went to the government and met with the prime minister. It took almost 10 years but it is now fully protected. It's an example that it takes time and it's hard work, but change can happen and photography can be a big tool in that. JTV: How do you choose between sharing stunning images of the natural environment and these painful truths of what we're doing to the environment? SG: A friend of mine did a study for her PhD: she set up a photo gallery using some of my images that showed beautiful pictures with a donation box, then a gallery with hard-to-look-at reality images and a donation box. Then she did a third one that showed both, and a donation box. The first two received about the same amount of donations. It was the third one, showing the balance of the two, that got the most amount of donations. We need and we deserve to see both sides. But we also need to help people to fall in love with the ocean and care about it, and you're going to do that by showing mostly the beauty, in my opinion. JTV: How do you get to know the creatures you photograph, and how does getting to know them influence your work? SG: For me as a kid I know when I would go to the school library and take out a book, there were certain pages I would stop on: 'Wow, look at this fish called the royal grandma. It's half purple and half yellow, isn't that amazing?' I know that could happen for somebody else, and inspire them. It's about finding out what it is about the species or habitat you can show in as cool of a light as possible. Ryan MacDonald: Are there specific issues you want to bring to the forefront in this day and age? Cristina Mittermeier: Canada is a magnificent country. We can choose to coast and feel lucky that we have these resources, or we can be leaders. When I think of the high seas treaty and the countries that have yet to sign it, people are no longer looking at the United States for leadership, but they're going to be looking at us. So much of that hinges on public support. The work that I do is galvanizing public attention, maybe showing you something that you hadn't thought about before and the next time you read about it you'll know it's important. RM: Your photo of kelp speaks to relatability, and it also speaks to conservation. Can you tell us why something like kelp matters as much as all the other images of these beautiful creatures? CM: The ocean is the ecosystem that allows life to exist on planet Earth; it produces half of the oxygen we breathe. Biomes like kelp, like sea grass, are part of this machinery that's absorbing carbon dioxide. The ocean has absorbed 90 per cent of the excess heat on the planet, and now you can see it's no longer able to cope. We were in Indonesia six months ago and the water was 32.5 degrees — just uncomfortable for a human. Imagine what it's like for fish. As a result, we're seeing ecosystems degrade. We need to keep the ocean alive. RM: Tell us about your foundation, how does that figure into your work? CM: SeaLegacy was born when my husband (Paul) and I were shooting an assignment for National Geographic on the Pacific blob (mass of warm water) in 2017, and the temperature of the water from California to Alaska was four to seven degrees warmer than it's supposed to be. The fish sunk to deeper, cooler water, so animals like sea lions were starving. There was also an overabundance of some algae. When it gets too warm they over-bloom and produce toxic substances; when animals eat it, they experience full-body paralysis. It was a horrific thing to photograph, just thousands of dead animals. Paul said to me, 'we have to do more.' We decided to leave National Geographic and start a non-profit. The idea was to take our images and ability to communicate and shine light on the beautiful solutions happening and also on the horrors, to give hope and be a reminder. RM: We're in a fight for truth around the world, so I want to talk a bit about what you're doing to fight against artificial intelligence in image making. CM: It's such a threat to the work of any creative, and the saddest part of it is that we didn't know. When you start uploading your photos to (social media), the tiny little print said they could use all that data to train their robots. The first defence we have is our reputation, truthfulness and credibility. But the second one is I'm part of a coalition of photographers that started an app that opts images out of AI training. We're trying to turn the tap off.
