Archaeologists are uncovering a mysterious pyramid-shaped structure and way station in the Judaean Desert. The excavation site, just north of the valley of Zohar (Nahal Zohar) along the coast of the Dead Sea, contains a host of exceptionally well-preserved artifacts that are more than 2,000 years old.
"The discoveries are exciting and even emotional, and their significance for archaeological and historical research is enormous," Eli Escusido, director of the Israel Antiquities Authority, said in a statement.
The pyramid is built from hand-cut stones, each weighing hundreds of pounds. But the structure's purpose is still unknown, according to the site's excavation directors. It may have served as a historical monument, a grave, or a guard tower protecting a commercial route from the Dead Sea to coastal ports.
The site dates back 2,200 years to the time of the Ptolemaic dynasty and Seleucid Empire. After Alexander the Great died in 323 B.C., his generals divided his vast empire among themselves. His general Ptolemy took control of Egypt and the surrounding areas, including Israel, while Seleucus ruled the northern part of what is now the Middle East. By 200 B.C., the Seleucid Empire had conquered what is now modern-day Israel.
Given that the pyramidal structure dates to the time of this power switch, it's unclear if it was built under the rule of the Ptolemaic dynasty or the Seleucid Empire. The Roman Empire absorbed both empires in the first century B.C.

The archaeologists also unearthed a number of artifacts at the site. The low-moisture environment of the desert likely helped preserve the artifacts through the millennia. Low humidity deters mold and minimizes warping and cracking in organic materials like wood and fibers.
"The extreme dryness has preserved things here in an extraordinary way," archaeologist Ido Zangen, who was involved with the excavation, said in a translated video released by the Israel Antiquities Authority. "We're finding papyrus fragments, all kinds of amazing wooden artifacts, baskets and ropes that you simply don't find anywhere else in the country."

Some of the papyrus fragments contain writing in ancient Greek, one of the languages spoken by denizens of both the Ptolemaic and Seleucid empires. Also among the unearthed artifacts are bronze coins and vessels, remnants of ancient furniture, beads, weapons, fabrics and seeds, all preserved by the dry climate.
Eva Balbin Brafman, a volunteer at the excavation, described finding part of a papyrus document from the upper part of the site. "You could clearly make out the letters, probably in Greek," Balbin Brafman said in the video. "It's incredibly exciting to find something in such a wonderful state of preservation."
A team of professional archaeologists and volunteers will continue to excavate the site through April 8 in hopes of learning more about the structure.

Scientists discover strong, unexpected link between Earth's magnetic field and oxygen levels

When you buy through links on our articles, Future and its syndication partners may earn a commission. Earth's magnetic field and oxygen levels are inextricably linked, new research suggests. The strength of the geomagnetic field has gone up in lockstep with the percentage of oxygen in Earth's atmosphere over the past 540 million years, a new study finds — but it remains unclear if one of these influences the other, or whether other unknown factors explain the link. "This is the first discovery we've ever had to establish the link between the geomagnetic field and the oxygen level," lead author Weijia Kuang, a senior scientist in the Geodesy and Geophysics Laboratory at NASA's Goddard Space Flight Center, told Live Science. Earth's magnetic field and oxygen levels have increased more or less in parallel since the start of the Cambrian period (541 million to 485.4 million years ago), and both factors spiked between 330 million and 220 million years ago, the results indicate. The research could help to narrow down requirements for life on other planets, Kuang and study co-author Ravi Kopparapu, a planetary scientist at the NASA Goddard Space Flight Center, said in a joint video interview. It may be that the geomagnetic field controls oxygen levels, or vice versa — but there is another possible scenario, which is that both factors are related to a third geochemical or geophysical process that the researchers haven't yet pinpointed, Kuang said. For the new study, scientists used two independent datasets spanning the past 540 million years. One of the datasets showed atmospheric oxygen, derived from multiple indicators such as the abundance in sediments of fossilized charcoal, which remains after wildfires and gives clues about how much oxygen was available at a given time. The other dataset showed the strength of the geomagnetic field, derived from magnetic information that is recorded in ancient rocks and sediments. The researchers plotted these datasets against each other and found there was a strong correlation between them. If the geomagnetic field controls oxygen levels, its influence would likely be due to the protection it offers Earth's atmosphere against space weather. Previous research indicates that the geomagnetic field can prevent or reduce the escape or erosion of atmospheric molecules. The magnetic field also shields life on the planet, including plants that produce oxygen, from X-ray and extreme ultraviolet radiation. If, in contrast, atmospheric oxygen levels dictate the strength of Earth's magnetic field, then plate tectonics would play a central role. Plate tectonics is the process that continuously recycles Earth's crust into the mantle, which is the planetary layer that covers Earth's liquid outer core. Earth's geomagnetic field originates from currents in the outer core, so it's possible that the recycling of crustal material and oxygen into the mantle could impact the lower mantle, which could then affect the geomagnetic field, Kuang said. Related: Did plate tectonics give rise to life? Groundbreaking new research could crack Earth's deepest mystery. "Plate tectonics [...] will definitely impact the thermal and the dynamical conditions at the base of the mantle where it borders the liquid outer core," he said. "On the other hand, plate tectonics also impacts the cycling of chemicals and other elements from the interior to the surface, which certainly will impact oxygenation, or the production of oxygen." It's more likely that the geomagnetic field affects oxygen levels, rather than the other way round, Kuang said. That's because scientists know the geomagnetic field originates deep inside the planet and propagates to Earth's surface and into space. "The other direction is less well understood," he said. The third possible scenario is that another, separate process is pushing the geomagnetic field and oxygen levels in the same direction over time. The study's authors don't know what that process might be yet, but a spike that exists in both datasets may hold the answer. The spike coincides with the existence of the ancient supercontinent Pangaea, which formed about 320 million years ago and broke up about 195 million years ago. Due to the massive tectonic rearrangements involved, supercontinents might be the missing link between Earth's magnetic field and oxygen levels — but the evidence for this is still very tentative at this point, Kuang and Kopparapu cautioned. "This is one of the conjectures we didn't really put out strongly in our paper, but it is something we think is a very enticing mechanism for us to pursue," Kuang said. The reason the researchers held back with this idea is that they have robust data for only one supercontinent — Pangaea — and not the ones that came before, he said.

"However, we don't have reliable data for oxygen [going farther back] than 540 million years, and so we are unable to make that kind of a conclusion for [farther back in time] and past supercontinents." The researchers are already working on the next step, which is to search for other geophysical and geochemical factors that might link to the geomagnetic field and oxygen levels. For this, the authors say communication and collaboration between scientists is of paramount importance. "One single mind cannot comprehend the whole system of the Earth," Kopparapu said. "We're like kids playing with Legos, with each of us having a separate Lego piece. We're trying to fit all of it together and see what's the big picture."

Cillian Murphy Is Amazing In 28 Days Later, But I Was Shook By The A-Listers Who Originally Vied For The Role

When you buy through links on our articles, Future and its syndication partners may earn a commission. I'm still amazed that director Danny Boyle and writer Alex Garland have reassembled to deliver a new tale of terror to the 2025 movie schedule in 28 Years Later. The occasion has left me also thinking about 28 Days Later a lot, a film that would eventually become known as Academy Award winner Cillian Murphy's star-making performance. But while the Oppenheimer lead has always been pitch perfect in the role of Jim, there's a long existing list of names that have been rumored to be up for the part back in the day. And when I say names, I truly mean 'names,' like Leonardo DiCaprio, Ryan Gosling and frequent Boyle collaborator Ewan McGregor. When the opportunity to watch the first 28 minutes of 28 Years Later was paired with an in-person interview with its intrepid director, I had to try and weed out fact from fiction, which saw all three names debunked in the process. However, that's when Danny Boyle gave CinemaBlend two names I never expected to be in the mix: I'll tell you who did audition for Jim. … Tom Hardy and Orlando Bloom, because they'd all finished either drama school or Black Hawk Down. … We didn't have very much money, we thought 'We'll never be able to afford a bigger actor.' And we wanted newbies who just didn't know which way it would break with them. So the trio of Leonardo DiCaprio, Ryan Gosling and Ewan McGregor were never going to even make the list for 28 Days Later's casting. With that being said, I'm very surprised that Tom Hardy and Orlando Bloom hadn't been reported more often - especially at that point in their careers. Although coincidentally enough, McGregor was in Black Hawk Down himself, as well as entrenched in the Star Wars prequel trilogy at the time. Likewise, by the time Danny Boyle's film was making the rounds in its initial 2002 release in the UK, Hardy and Bloom were going head to head at the box office thanks to their respective roles in Star Trek: Nemesis and The Lord of the Rings: The Two Towers. Honestly, either man would have been a distraction to the tense, harrowing journey 28 Days Later took, as audiences would know they'd survive the ride. The whole point of the third act is that by time Jim's on his rampage through Major West's estate, you're supposed to wonder if he's an Infected at that point. While we now know that wasn't the case, and with Cillian Murphy set to return for 28 Years Later's sequel The Bone Temple, that point tends to get a bit lost. However, Danny Boyle's perspective seemed to see him pick between two finalists, with the Christopher Nolan vet winning out in the end. At least, that's what it sounded like when the 28 Years Later mastermind shared this with CinemaBlend: And I remember seeing [them], and we saw Cillian, and I remember thinking, 'Whoa, he'll have an amazing career.' I remember thinking that. I was right. I remember thinking that about Orlando Bloom, I thought 'He'll do all right. ' The rest, as they say, is history. 2003's US release lit a fuse that saw both Cillian Murphy and Naomie Harris both launch into higher profile roles, and Danny Boyle and Alex Garland being heralded as the men who reanimated the zombie (and zombie-adjacent) subgenre. Seeing as Stephen King bought out showings of 28 Days Later just so he could give them out to spread the word, that was clearly the right choice. And as Danny Boyle himself suggested, Orlando Bloom and Tom Hardy did 'do alright' in the end. Let's hope that 28 Years Later renews its franchise's King Seal of Approval, when it opens in theaters on June 20th.

Proposed NASA radio probe could use gravity 'lumpiness' to reveal the insides of alien worlds

When you buy through links on our articles, Future and its syndication partners may earn a commission. Engineers have designed a compact, battery-powered radio probe that could help unlock the secrets of alien planets. The proposed small probe, known as the Gravity Imaging Radio Observer (GIRO), would use gravity fields to precisely map the interiors and compositions of exoplanets and other celestial bodies. "GIRO is a small radio probe that reflects radio signals sent from the host spacecraft that carried and released it," Ryan Park, principal engineer at NASA and supervisor of the Solar System Dynamics group at the Jet Propulsion Laboratory, told in an email. Park and his colleagues have designed GIRO to measure subtle variations in the gravitational fields of planets, moons and asteroids. They described the concept for the new probe in a paper published May 29 in The Planetary Science Journal. "As the probe and the host spacecraft orbit (or fly by) a target body together in formation, variations, or 'lumpiness,' in the body's gravity field cause very small changes in the orbits of both the probe and the host spacecraft," Park said. "These changes can be measured using the Doppler effect in the radio signals." By analyzing these Doppler signatures and mapping these gravity fields with high precision, researchers can infer the internal structure and dynamics of planets, moons and other celestial bodies. This insight helps answer fundamental questions about their mass, density, composition, formation history, and potential for geologic or volcanic activity — making GIRO a powerful, high-precision tool for future space exploration missions. "GIRO would be particularly useful — and even essential — for problems that require the recovery of high-accuracy gravity fields, exploration of risky environments, and/or situations with limited data acquisition opportunities," Park said. High-accuracy gravity data is crucial in situations where the gravitational signal is faint, such as determining the mass of a small asteroid or detecting changes in the gravity field of a planetary moon over time. "Risky environments refer to places where it is practically challenging to conduct flybys or orbits," Park explained. A good example is the complex and potentially dangerous environment posed by the rings of Uranus. "Limited data acquisition applies to cases where only a handful of flybys or a short period of orbiting are feasible," he added. The battery-powered, spin-stabilized probe's high accuracy, low cost and ability to carry multiple probes at once could help solve these challenging problems. "Compared to conventional ground-based radiometric tracking, GIRO is expected to provide accuracy that is 10 to 100 times better," Park said. "This level of precision is important for planetary science because it allows for much more detailed mapping of gravity fields, revealing subtle features of a planet or moon's interior structure." By matching the basic capabilities of past missions like GRAIL, GIRO can cut costs and complexity by using lightweight, low-power radio components while delivering accurate gravity measurements, according to Park. This means "gravity science can be conducted as part of broader exploration missions rather than requiring dedicated spacecraft," he explained. In addition, GIRO may open the door to exploring smaller celestial bodies and remote planetary systems that might advance our understanding of how planets form and evolve and whether they might harbor the conditions for life. Designing a GIRO gravity experiment comes with its own set of challenges, most of which revolve around how the mission is planned. To get accurate data, the probes must be released into carefully chosen orbits that not only allow for precise gravity measurements but also maintain a strong radio connection with the main spacecraft. For outer-planet missions, GIRO probes will be battery-powered, so all measurements must be completed before the batteries are depleted after 10 days. However, for missions closer to the sun, there is an option to recharge batteries using sunlight. RELATED STORIES —Leaping robots, fusion satellites and more!

According to Park, GIRO could technically be integrated into a planetary mission within one to three years. Though budgetary and political constraints would influence this timeline. "The most important milestones before integration involve building and testing flight-like prototypes in environments that closely simulate actual mission conditions," Park said. "Once these milestones are met and a mission opportunity is identified, GIRO could be incorporated into the payload for upcoming missions, such as those targeting asteroids, moons or outer planets."
