Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction, could transform imaging, telecommunications, and countless other technologies. Now, a team of scientists has managed to use a natural magnetic material called CrSBr to achieve negative refraction—without the need for complicated artificial structures. The study, published in Nature Nanotechnology, opens the door to ultra-compact lenses, super-high-resolution microscopes, and reconfigurable optical devices that can be controlled with magnets.
Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error mitigation and specialized circuits on a 91-qubit superconducting quantum processor. Their results are published in Nature Physics.
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, all without the use of traditional optical elements like lenses and mirrors. Their breakthrough provides experimental evidence of a peculiar natural phenomenon that had been confined mostly to theory.

The mythology which has been built up around him has endured for centuries, even though most have no idea exactly where the character of Merlin came from. Also, was Merlin benevolent or malevolent? ![]() So where exactly did the legend of Merlin start, and how exactly is he connected to King Arthur? According to a fascinating article found on the website Ancient Origins, the story of Merlin is a complex one filled with contradictions and mysteries:
![]() The first mention of Merlin can be found in The History of Kings of Britain, which was written in 1136 AD by Geoffrey of Monmouth. Much of the work is a historical record of English kings, Merlin is found, but as a fictional character:
Son of the devil and servant of God? That certainly makes Merlin an object of fascination, if for no other reason than such a description makes us question his motives and what role he played in Arthur’s kingdom. Part Madman, Part WarriorThe character of Merlin was actually a composite of several historical figures who were well-known to readers of the time:
Notice the dichotomy once again: Merlin was part madman and part warrior. That alone suggests that his “magic” may have been little more than the rantings of a lunatic who was bent on attaching himself to power. And no one was more powerful than a king. ![]() Ambrosius is of particular interest because he shows up in relation to another British king, Vortigern, who wanted to erect a tower. However, each time Vortigern tried to build the tower, it would collapse. The only way the tower would ever stand required a bizarre ritual:
Geoffrey, in his telling of the Merlin legend, notes that Merlin was also fatherless, but he also retained the character of Ambrosius. ![]() Another change Geoffrey makes is that in the story with Merlin and King Vortigern, Merlin’s prophecies are included. Those prophecies point directly to the ultimate crowning of Arthur as king of Britain. And in doing so, Geoffrey introduces the notion that King Arthur was the fulfillment of a prophecy, giving him a magical air. Merlin, Stonehenge, and Giants?One of those prophecies was how Arthur came to be. Another explains Stonehenge’s appearance:
![]() Merlin the ShapeshifterThe name Merlin is also found in a poem written by Robert de Boron. The poem was written long after Merlin had first been introduced in The History of Kings of Britain. However, Boron’s poem focuses more on Merlin’s magical abilities:
Merlin was also shown in some writings as a mentor and tutor to King Arthur, giving him advice on difficult situations facing the kingdom. Other depictions of Merlin, however, were much less charitable:
![]() Today, most of us know Merlin as the benevolent tutor to King Arthur who often used his rapier wit to defuse potentially dangerous situations. Depictions of Camelot almost always place Merlin in a prominent position even though he wasn’t allowed to sit as a Knight of the Round Table. Over the centuries, Merlin has undergone many manifestations, from good to evil and back again. Despite all of the contradictions found in a close reading of works that deal with Merlin, he remains one of the most fascinating figures in all of mythology.

The search for life-supporting worlds in the solar system includes the Jovian moon Europa. Yes, it’s an iceberg of a world, but underneath its frozen exterior lies a deep, salty ocean and a nickel-iron core. It’s heated by tidal flexing, and that puts pressure on the interior ocean, sending water and salts to the surface. As things turn out, there’s also evidence of ammonia-bearing compounds on the surface. All these things combine to provide a fascinating look at Europa’s geology and potential as a haven for life.
SpaceX is requesting permission to launch as many as 1 million satellites into the Earth’s orbit in order to pull off Elon Musk’s latest grand vision of putting data centers in space to do complex computing for artificial intelligence. In a filing with the Federal Communications Commission made on Jan. 30, SpaceX said it’s creating the solar-powered network in order to “accommodate the explosive growth of data demands driven by AI.”
A tomb containing a 2,000-old-year old skeleton was recently unearthed in the Russian republic of Kabardino-Balkaria, and it appears the remains are of an ancient warrior woman who lived during the height of the Roman Empire, according to the Daily Mail:
Of particular interest to the archaeologists who found the tomb was the jewelry discovered at the same time, including two “very valuable rings” with dark glass centers. Archaeologist Anna Kadieva noted:
The woman is thought to have been from the Alans warrior people who arrived in Caucasus in the 1st and 2nd centuries AD, Ancient Origins reports. The rings were likely “Roman made,” and a description of them highlights just how much work went into producing the items:
The Caucasus ConnectionThough most of us have heard of the Caucasus region, you may not know that it was once a region of great importance because the isthmus itself is a land bridge between the Eurasian steppes and Western Asia. So it served as a way to pass between Europe and Asia during the days that Rome was the dominant power across much of the known world. It is also a region rich with reminders of the planet’s early history:
Finding the Origins of Ancient WarriorsThousands of years ago, the people in the region were equally dispersed along the shores of the Black and Caspian Seas and in the Kura and Arax River basins. And over the past couple of decades, there has been extensive archaeological excavations in the locations that were home to the majority of the population. The results of those international missions have yielded a great deal of new finds. All of this leads researchers to speculate that the jewels found in the Russian tomb may have been “jewels of war,” Ancient Origins notes:
![]() In 69 AD, the Roman Empire was in the midst of a bloody civil war, and part of that took place in the Caucus region that is home to the warrior tomb:
![]() Further studies into the finds are planned, but for now, we have a glimpse into history that may well wind up adding even greater illumination to what we know about the Roman Empire and how it came to a sudden end.

In some solid materials under specific conditions, mutual Coulomb interactions shape electrons into many-body correlated states, such as Wigner crystals, which are essentially solids made of electrons. So far, the Wigner crystal state remains sensitive to various experimental perturbations. Uncovering their internal structure and arrangement at the atomic scale has proven more challenging.
