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.

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.

Boeing Stock Set for a Ride as NASA Progresses in Artemis II Program
NASA's Artemis II mission, the first crewed flight in its lunar return program, set to launch in April 2026, has reached critical milestones in recent months, reigniting investor interest in aerospace giant Boeing BA, a key contractor in the Space Launch System (SLS) program. On July 2, 2025, NASA announced on its Facebook page that the Program Specific Engineering Test for the Artemis II core stage had been completed. In early June, the Artemis II team conducted its first mission simulation to rehearse lunar science operations for the upcoming crewed mission. Earlier, in March, the integration of the Artemis II SLS core stage with its solid rocket boosters was successfully completed, which was another key milestone in preparing the rocket for launch. To this end, it is imperative to mention that the SLS rocket, designed to carry astronauts farther into space than ever before, is led by Boeing as the prime contractor for its core stage, upper stage, and avionics systems. The jet giant is currently building the core stages for all future Artemis missions. Thus, for Boeing, Artemis II represents more than just a technological triumph — it's a strategic revenue driver. With the company's Defense, Space & Security segment accounting for nearly 36% of total revenues in 2024, space programs like Artemis are key to Boeing's efforts to gain from a diversified portfolio beyond its struggling commercial aviation business and provide it with a significant financial cushion. With Artemis II on track, NASA's commitment to sustaining the Artemis program through Artemis III and beyond implies recurring revenue potential for Boeing over the long run, given its deep involvement in every SLS flight configuration. As investor interest in space stocks has been gaining increasing traction these days, the continued success of the Artemis mission should strengthen Boeing's positioning in the $500 billion global space economy and offer a promising growth vector for its shares. The potential upside reflected in BA's price target further supports this thesis. Based on short-term price targets provided by 22 analysts, the average Zacks price target for Boeing implies a 6.4% upside from its last closing price. Other Space Stocks Warrant a Look Other stocks, involved in the SLS program and Artemis missions, like Lockheed Martin LMT and L3Harris Technologies Inc. LHX, also stand to benefit from the steady progress of the Artemis II mission. Notably, Lockheed is the prime contractor involved in the construction of Orion, the spacecraft that will carry the crew of four astronauts in the Artemis II mission. In May 2025, LMT achieved a significant milestone in the development of NASA's Orion spacecraft by officially transferring it to NASA's Exploration Ground Systems team, following the completion of the spacecraft's assembly and testing. On the other hand, L3Harris is involved in the Artemis II mission through its Aerojet Rocketdyne business unit, which provides the RS-25 engines that power the SLS core stage. In May 2025, Aerojet Rocketdyne completed installation of all four RS-25 main engines on the core stage of NASA's second SLS exploration rocket, which will be used in the Artemis II mission. The Zacks Rundown for BA Shares of Boeing have risen 22% year to date compared with the industry 's growth of 22.2%. From a valuation standpoint, BA is currently trading at a forward 12-month sales multiple of 1.80X, a roughly 18.9% discount when stacked up with the industry average of 2.22X. The Zacks Consensus Estimate for BA's 2025 and 2026 sales implies a year-over-year uptick of 25.6% and 16.2%, respectively. The same for its earnings per share for 2025 has moved north over the past 60 days, while the same for 2026 has moved south. BA stock currently carries a Zacks Rank #3 (Hold).
