This latest research adds weight to the ongoing debate about the origins of one of history’s most iconic dinosaurs. By using advanced mathematical modeling, Morrison and his team traced the likely migration of tyrannosaurids — the group that includes T. rex — across the ancient Bering Strait from Siberia to Alaska during the late Cretaceous period.

Morrison explained that, back then, the region resembled today’s temperate rainforests of British Columbia, creating an environment where these fearsome carnivores could thrive. Tyrannosaurids, though dominant predators, were outnumbered by the plant-eating dinosaurs they hunted, making their fossils far less common and challenging to uncover in the present day.

To overcome gaps in the fossil record, the team used models combining existing fossil data, evolutionary family trees, and environmental conditions. Their findings indicate that more undiscovered fossils of T. rex ancestors could still be hidden in Asia, waiting for future paleontological discoveries.

One major revelation from the study is that tyrannosaurids experienced a rapid increase in body size as the planet cooled, possibly aided by insulating feathers or warm-blooded physiology. This growth surge coincided with the extinction of another group of giant predators, the carcharodontosaurids, roughly 90 million years ago. With their rivals gone, tyrannosaurids rose to the top of the food chain, eventually producing behemoths like T. rex, which weighed as much as 9 metric tons — comparable to a large elephant or a light tank.

Study coauthor Charlie Scherer noted that this extinction event “likely removed the ecological barrier that prevented tyrannosaurs from growing to such sizes.” The result was the rise of the largest tyrannosaurs in both North and South America by the end of the Cretaceous period.

Paleontologist Steve Brusatte, who was not involved in the study, praised the work for its detailed analysis of how tyrannosaurs and other predators evolved alongside changing climates. He remarked that even the most dominant dinosaurs were shaped by environmental factors, with cooler temperatures providing an advantage for bigger bodies.

Ultimately, the new findings suggest that the rule of the T. rex in North America was the result not just of fierce competition, but also of migration, extinction, and shifts in the prehistoric climate — painting a more dynamic portrait of dinosaur evolution than ever before.

Federal regulators have cleared SpaceX to proceed with another Starship test flight after a series of highly publicized explosions earlier this year. The Federal Aviation Administration issued an updated license on May 15, enabling SpaceX to conduct its ninth Starship launch from South Texas. This approval came even as the investigation into the most recent failure, which scattered debris near the Bahamas, remains open.

The FAA said its decision followed a review confirming that SpaceX met all safety, environmental, and licensing requirements. The green light represents the final regulatory hurdle for SpaceX to expand from five to 25 annual Starship launches at Boca Chica, Texas—a leap forward in the company’s push for rapid development and frequent flights.

Hazard Zones Widen as FAA Reacts to Prior Mishaps

After debris from previous Starship flights landed on islands in the Caribbean and Atlantic, the FAA mandated significant changes for Flight 9. The agency will expand the Starship hazard area from 1,018 to 1,841 miles to better protect aircraft and maritime traffic. Up to 175 flights may be affected, with potential delays averaging 40 minutes each. To reduce disruption, the launch window will avoid peak transit periods, although SpaceX has not announced a target date for the mission.

Increased oversight now requires SpaceX to update its flight safety analysis for each test, calculating new hazard areas and mapping debris response zones. The FAA continues to coordinate with authorities in the Bahamas, Turks and Caicos, the UK, Cuba, and Mexico. So far, there have been no reported injuries, but the FAA confirmed at least one property damage incident when a Starship fragment struck a car in South Caicos earlier this year.

Super Heavy Reusability and the Next Test Milestone

SpaceX is set to attempt a key goal during Flight 9: the reuse of its Super Heavy booster, a massive 232-foot-tall cylinder equipped with 33 engines. The company has already recovered three Super Heavy boosters, aiming to dramatically reduce launch costs through refurbishment. For now, Starship prototypes have only reached suborbital altitudes, and further breakthroughs are needed before crewed missions can proceed—including the development of in-orbit refueling and life support systems.

SpaceX’s ‘Explode to Learn’ Approach

Unlike NASA’s conservative, ground-test-heavy approach, SpaceX uses “rapid iterative development.” This means launching frequent, relatively inexpensive prototypes—even if they fail—to speed up design improvements. Elon Musk and his team argue that learning from real-world failures accelerates progress and innovation. Each test, successful or not, produces data that feeds back into new designs and safety measures.

NASA’s Bet on Starship for Lunar and Mars Missions

Despite past mishaps and the controversy surrounding Musk’s leadership, Starship is crucial to NASA’s long-term goals. The agency has already committed up to $4 billion for two lunar landing missions. If the White House moves forward with plans to retire NASA’s own SLS rocket—criticized for its steep $2–4 billion per launch price tag—Starship could soon become NASA’s only option for reaching the Moon or Mars.

The agency is awaiting Senate confirmation for a new NASA chief who backs Musk’s vision, potentially cementing SpaceX’s role in future deep space exploration. Meanwhile, Starship’s price per test flight remains a fraction of legacy costs, typically $50–100 million, but major technical hurdles remain before regular, crewed interplanetary missions can begin.

What’s Next for SpaceX and Starship?

With FAA approval in hand, SpaceX prepares to test both its most ambitious reusability milestone yet and its ability to operate within stricter safety regimes. The coming Flight 9 launch will not only demonstrate technical progress but also test the evolving partnership between private spaceflight and government oversight.

Whether Starship can overcome its fiery setbacks and deliver on its promise of affordable, frequent access to space will depend on both engineering breakthroughs and continued regulatory cooperation. For now, all eyes are on Boca Chica as SpaceX gears up for the next chapter in the Starship saga.

Voyager 1, which launched in September 1977, is currently traveling more than 15.5 billion miles (25 billion kilometers) away from Earth, far outside the heliosphere — the bubble of magnetic fields and particles created by the Sun. The spacecraft relies on multiple thruster sets to keep its antenna accurately pointed toward Earth, ensuring a steady stream of data from the edge of interstellar space.

Within the primary thruster system are roll thrusters, which maintain the spacecraft’s orientation by keeping it pointed at a guide star. Voyager 1’s original roll thrusters ceased functioning in 2004 after internal heaters lost power. Since then, the spacecraft has relied on backup roll thrusters for orientation. But over time, tiny amounts of propellant residue threatened to clog these backup units, risking the mission’s future.

With the threat of both thruster failure and an upcoming months-long pause in communications due to upgrades on the key Deep Space Network antenna in Canberra, Australia, engineers had to act fast. If both sets of roll thrusters failed, Voyager 1 could lose its ability to point toward Earth, ending a mission that has lasted nearly five decades.

NASA’s Jet Propulsion Laboratory team took a bold approach: they theorized that a disturbance in the circuitry might have simply flipped a switch in the wrong direction, cutting off power to the heaters. If they could reset the switch, it might restart the heaters and revive the original roll thrusters — units thought to be ‘dead’ for 20 years. But the maneuver was risky, since any malfunction could send the probe spinning out of alignment or even cause minor explosions if fuel lines froze.

The team sent a command to Voyager 1 on March 19 to activate both the heaters and thrusters. Then, they waited — more than 23 hours for data to travel back across the vast distance. When the telemetry finally arrived on March 20, it showed a dramatic rise in heater temperature, confirming that the thrusters were back online and operational. The fix was a relief for the mission team and marked yet another remarkable chapter in Voyager’s journey.

With this successful revival, Voyager 1 remains on track to continue sending invaluable data from the frontier of interstellar space, even as NASA temporarily loses direct command capabilities during the Deep Space Network upgrades. The mission’s resilience stands as a testament to the ingenuity and creativity of the engineers behind one of humanity’s greatest scientific adventures.

A Ritual Bath in the Heart of Ancient Rome

The mikveh was unearthed during recent excavations at Ostia Antica, a city located just 16 miles from Rome that once served as the Empire’s first colony and a key maritime hub. The ritual bath, used in Judaism for ceremonial purification, is thought to have been supplied with natural spring or rainwater, in line with religious law.

Architectural and Religious Significance

Steps lead down into the structure, which is tucked within a small room of the ancient Ostia Synagogue — itself believed to have been built toward the end of the 2nd century AD. The mikveh is framed by columns and adorned with blue plaster and decorative shells, offering both functionality and a touch of elegance.

“This is an absolutely extraordinary discovery,” said Alessandro D’Alessio, director of the Archaeological Park of Ancient Ostia. “Until now, no Roman mikva’ot had been found outside of Judea, Galilee, or Idumea. This confirms the deep-rooted presence and cultural importance of the Jewish community in Ostia during the Imperial age, and likely even earlier.”

A Crossroads of Cultures

Italy’s Minister of Culture, Alessandro Giuli, echoed this sentiment, describing the find as symbolic of the multicultural fabric of ancient Roman civilization. “The discovery of this mikveh confirms Ostia as a historic crossroads of cultural exchange and coexistence, a city that embraced tolerance within the Roman world,” Giuli said in a statement.

Other Artifacts Found at the Site

Alongside the mikveh, archaeologists uncovered a collection of small statues, marble fragments, and other significant relics. Among the standout finds were a lamp bearing the image of a menorah and palm branch, and a well-preserved glass goblet — both dated between the 5th and 6th centuries AD. These items further reinforce the narrative of a thriving Jewish presence in Ostia over multiple centuries.

Ostia: A City Frozen in Time

Initially founded as a naval base, Ostia’s ruins have been remarkably well preserved thanks to layers of protective sand dunes. Sometimes likened to Pompeii in terms of archaeological richness, much of Ostia remains buried — with only around one-third of the city excavated to date.

Excavation Efforts and Historical Context

Excavations began under the regime of Benito Mussolini but were halted during World War II. Sporadic digs resumed in later decades, with a new wave of research launching in 2022. This latest effort is a collaboration between the Archaeological Park of Ancient Ostia, the University of Catania, and the Polytechnic of Bari, focused on two key areas of the buried city.

As per Jewish law, the mikveh had to be filled with naturally sourced water and deep enough to allow for full-body immersion. “It adheres to all the religious criteria,” confirmed D’Alessio, who emphasized the importance of the site’s preservation and study.

Calls for Public Access and Preservation

Alfonsina Russo, head of Italy’s department for the promotion of cultural heritage, urged that the mikveh be made publicly accessible as soon as possible. Her sentiment was echoed by Riccardo Di Segni, the chief rabbi of Rome, who called the discovery “a precious addition to the history of Roman Jewry.”

“This find not only enhances our understanding of Jewish life in ancient Rome,” Di Segni said, “but also highlights the care taken to preserve tradition even far from its birthplace. The mikveh is both functional and refined — a testament to the cultural depth of this historic community.”

With ongoing efforts to restore and open the site to the public, this extraordinary find is poised to become a vital piece of Rome’s cultural and religious mosaic, connecting modern observers with a long-overlooked chapter of the city’s ancient history.

Uncovering a Hidden Chapter of Human Prehistory

The groundbreaking find, detailed in a study published in the journal Nature, includes 27 shaped bone fragments — primarily long bones — that show deliberate crafting using stone implements. Most of the tools were located in a gully within Olduvai Gorge, a place often referred to as the “Cradle of Humankind.”

Systematic Craftsmanship and Cognitive Evolution

Unlike earlier sporadic finds of bone tools, these items appear to have been crafted using the same techniques applied to stone tools — a deliberate and systematic process. The precision of the work suggests advanced cognitive abilities in early hominins. “They weren’t just reacting to their environment — they were innovating,” said Dr. Ignacio de la Torre, lead author of the study and co-director of the Olduvai Gorge Archaeology Project.

De la Torre believes this innovation represents a pivotal shift in hominin development. “These tools show a level of abstract thinking, a capacity to transfer learned skills from stone knapping to bone,” he said.

Olduvai Gorge: A Treasure Trove of Ancient Innovation

Olduvai Gorge has yielded some of the earliest known stone tools, dating back 3.3 million years. It has also revealed remains of hominins such as Homo habilis, Homo erectus, and early Homo sapiens. This new discovery adds a vital layer to our understanding of hominin innovation during the Oldowan and Acheulean technological periods.

Stone and Bone: A Technological Transition

During the Oldowan era (2.7–1.5 million years ago), early humans used basic stone tools created by chipping flakes from rocks. These tools evolved into more sophisticated forms during the Acheulean period around 1.7 million years ago, with the creation of almond-shaped hand axes requiring advanced knapping skills. The bone tools now uncovered suggest this technical leap wasn’t limited to stone alone.

The Tools and Their Origins

Each of the 27 bone tools was crafted from dense limb bones, predominantly from elephants and hippos — animals abundant in the East African landscape during that time. The tools ranged in size, with the largest made from elephant bones measuring up to 15 inches (38 centimeters) long.

Signs of Purposeful Design

Detailed analysis revealed that the bones had been chipped to form functional edges. Dr. Renata Peters of University College London emphasized their significance: “These weren’t incidental modifications. They were carefully shaped using a process nearly identical to stone knapping.”

The tools likely served various purposes — from butchering animals to producing other tools — although no direct use-wear evidence has been found yet. Still, their form and context strongly suggest practical application in daily life.

A Missing Piece of the Puzzle

While no hominin remains were found alongside the tools, researchers believe either Homo erectus or Paranthropus boisei — both known to inhabit the area — may have been responsible for the craftsmanship. The abundance of carcasses in the region may have offered a convenient raw material for experimentation with non-stone tools.

Organic Tools in a Fragile Archaeological Record

One reason bone tools are rarely found is that organic materials like bone deteriorate more easily than stone. This makes discoveries like the Olduvai cache exceptionally rare — and exceptionally valuable.

Global Impact and Future Directions

Other bone tools have been found at later sites in Europe and Asia, but rarely in such quantities or of such antiquity. The implications for understanding human evolution are profound.

“The fact that we’ve found not just one or two, but 27 bone tools indicates mass production,” said Dr. Jackson Njau, a coauthor of the study and Tanzanian archaeologist. “It shows early humans were expanding their toolkit beyond stone much earlier than we believed.”

Revisiting Collections with New Eyes

Experts like Dr. Briana Pobiner of the Smithsonian Institution believe this discovery opens the door for reevaluating existing museum collections. “These tools were once archaeologically invisible. Now that we know what to look for, it may change how we view early human ingenuity.”

Shaping the Past, Shaping the Future

As excavations at Olduvai Gorge continue, the team hopes to find further evidence to confirm the toolmakers’ identity and to better understand how this bone technology influenced later cultural advancements. For now, the discovery has already begun reshaping our narrative of early human behavior — and the remarkable minds behind it.

A Newfound Appreciation for an Unlikely Champion

The blobfish, a deep-sea dweller with a squishy physique and perpetually solemn expression, surged to victory in the two-week-long public vote. Garnering a total of 5,583 votes, it edged out its closest competitor — the orange roughy — by nearly 300 ballots. The competition, which closed on March 16, aimed to spotlight lesser-known aquatic creatures inhabiting New Zealand’s marine and freshwater ecosystems.

Behind the Blob

Scientifically known as Psychrolutes marcidus, the blobfish typically lives at depths of 2,000 to 4,000 feet (600 to 1,200 meters), primarily off the coasts of southeastern Australia and Tasmania. While its above-water appearance has earned it ridicule — with pale, drooping skin and bulbous features — scientists say that reputation is undeserved. At depth, where the pressure is immense, blobfish look considerably more ordinary. Their gelatinous structure allows them to withstand the crushing weight of the deep sea, but once brought to the surface, the lack of pressure causes their bodies to collapse into the iconic “blob.”

Public Support and a Viral Push

The blobfish’s ascent to stardom was not without help. According to the Trust, the orange roughy appeared poised for victory until the blobfish received a boost from national radio station More FM. Hosts Sarah Gandy and Paul Flynn, from the station’s popular Drive show, rallied public support in defense of the fish’s much-maligned image.

“The blobfish had been bullied its whole life,” said the duo. “He’s been quietly sitting at the bottom of the ocean, minding his own business, and we thought — it’s time for him to have his moment in the sun.”

More Than Just a Popularity Contest

Kim Jones, co-director of the Mountains to Sea Conservation Trust, described the final vote as “a battle of two quirky deep sea critters,” praising the blobfish’s “unconventional beauty” for tipping the scales. But beyond the playful competition lies a serious message: New Zealand’s unique aquatic life is under threat.

Raising Awareness Through Engagement

“Many of our freshwater and marine fish are found nowhere else in the world,” said Jones. “Climate change, pollution, and human land use are putting immense pressure on their habitats. Competitions like this help get people talking about species they may never have heard of, and that’s the first step toward conservation.”

• The blobfish can grow up to 12 inches (30 cm) long.
• It lacks strong bones or muscles — an adaptation suited to extreme ocean pressure.
• Its perceived “ugliness” only manifests outside of its natural deep-sea environment.
• The species is considered vulnerable, highlighting the need for marine protection.

Redefining Beauty in the Deep

The blobfish’s triumph is more than a quirky internet headline — it’s a reminder that value and beauty are subjective. In a world increasingly concerned with environmental sustainability, celebrating species like the blobfish is a powerful act of advocacy. As the Mountains to Sea Conservation Trust puts it, when people fall in love with nature’s oddities, they are more likely to protect them.

This year, the blobfish finally rose from the depths — not just of the ocean, but of public perception — to take its rightful place as a celebrated symbol of biodiversity and resilience.
