For decades, physicists believed that superconductivity and magnetism were fundamentally incompatible. Superconductivity is fragile: even a weak magnetic field can disrupt the delicate pairing of electrons that allows electrical current to flow without resistance. Magnetism, by its very nature, should destroy superconductivity.

And yet, in the past year, two independent experiments upended this assumption.

In two different quantum materials, researchers observed something that should not have existed at all: superconductivity and magnetism appearing side by side. One experiment involved rhombohedral graphene, while another focused on the layered crystal molybdenum ditelluride (MoTe₂). The findings stunned the condensed-matter physics community and reopened a fundamental question—how is this even possible?

Now, a new theoretical study from physicists at the Massachusetts Institute of Technology offers a compelling explanation. Writing in the Proceedings of the National Academy of Sciences, the researchers propose that under the right conditions, electrons in certain magnetic materials can split into fractional quasiparticles known as anyons—and that these anyons, rather than electrons, may be responsible for superconductivity.

If confirmed, the work would introduce a completely new form of superconductivity, one that survives magnetism and is driven by exotic quantum particles instead of ordinary electrons.

“Many more experiments are needed before one can declare victory,” said Senthil Todadri, William and Emma Rogers Professor of Physics at MIT, in a media statement. “But this theory is very promising and shows that there can be new ways in which the phenomenon of superconductivity can arise.”

A Quantum Contradiction Comes Alive

Superconductivity and magnetism are collective quantum states born from the behavior of electrons. In magnets, electrons align their spins, producing a macroscopic magnetic field. In superconductors, electrons pair up into so-called Cooper pairs, allowing current to flow without energy loss.

For decades, textbooks taught that the two states repel each other. But earlier this year, that belief cracked.

At MIT, physicist Long Ju and colleagues reported superconductivity coexisting with magnetism in rhombohedral graphene—four to five stacked graphene layers arranged in a specific crystal structure.

“It was electrifying,” Todadri recalled in a media statement. “It set the place alive. And it introduced more questions as to how this could be possible.”

Soon after, another team reported a similar duality in MoTe₂. Crucially, MoTe₂ also exhibits an exotic quantum phenomenon known as the fractional quantum anomalous Hall (FQAH) effect, in which electrons behave as if they split into fractions of themselves.

Those fractional entities are anyons.

Meet the Anyons: Where “Anything Goes”

Anyons occupy a strange middle ground in the quantum world. Unlike bosons, which happily clump together, or fermions, which avoid one another, anyons follow their own rules—and exist only in two-dimensional systems.

First predicted in the 1980s and named by MIT physicist Frank Wilczek, anyons earned their name as a playful nod to their unconventional behavior: anything goes.

Decades ago, theorists speculated that anyons might be able to superconduct in magnetic environments. But because superconductivity and magnetism were believed to be mutually exclusive, the idea was largely abandoned.

The recent MoTe₂ experiments changed that calculus.

“People knew that magnetism was usually needed to get anyons to superconduct,” Todadri said in a media statement. “But superconductivity and magnetism typically do not occur together. So then they discarded the idea.”

Now, Todadri and MIT graduate student Zhengyan Darius Shi, co-author of the study, revisited the old theory—armed with new experimental clues.

Using quantum field theory, the team modeled how electrons fractionalize in MoTe₂ under FQAH conditions. Their calculations revealed that electrons can split into anyons carrying either one-third or two-thirds of an electron’s charge.

That distinction turned out to be critical.

Anyons are notoriously “frustrated” particles—quantum effects prevent them from moving freely together.

“When you have anyons in the system, what happens is each anyon may try to move, but it’s frustrated by the presence of other anyons,” Todadri explained in a media statement. “This frustration happens even if the anyons are extremely far away from each other.”

But when the system is dominated by two-thirds-charge anyons, the frustration breaks down. Under these conditions, the anyons begin to move collectively—forming a supercurrent without resistance.

“These anyons break out of their frustration and can move without friction,” Todadri said. “The amazing thing is, this is an entirely different mechanism by which a superconductor can form.”

The team also predicts a distinctive experimental signature: swirling supercurrents that spontaneously emerge in random regions of the material—unlike anything seen in conventional superconductors.

Why This Matters Beyond Physics

If experiments confirm superconducting anyons, the implications could extend far beyond fundamental physics.

Because anyons are inherently robust against environmental disturbances, they are considered prime candidates for building stable quantum bits, or qubits—the foundation of future quantum computers.

“These theoretical ideas, if they pan out, could make this dream one tiny step within reach,” Todadri said.

More broadly, the work hints at an entirely new category of matter.

“If our anyon-based explanation is what is happening in MoTe₂, it opens the door to the study of a new kind of quantum matter which may be called ‘anyonic quantum matter,’” Todadri said. “This will be a new chapter in quantum physics.”

For now, the theory awaits experimental confirmation. But one thing is already clear: a rule long thought unbreakable in quantum physics may no longer hold—and the quantum world just became a little stranger, and far more exciting.

Artemis will be the first human mission to travel beyond low-Earth orbit since the Apollo era, and it is designed as a 10-day journey that will take astronauts on a flyby around the Moon before returning to Earth.

NASA is set to make history with the launch of its first crewed Artemis mission around the Moon, with liftoff targeted for April 1, 2026, marking humanity’s return to deep space exploration after more than five decades.

The mission, known as Artemis II, will carry four astronauts aboard the Orion spacecraft using NASA’s powerful Space Launch System rocket. The launch is scheduled from Kennedy Space Center in Florida, with additional backup launch opportunities extending through early April.

This will be the first human mission to travel beyond low-Earth orbit since the Apollo era, and it is designed as a 10-day journey that will take astronauts on a flyby around the Moon before returning to Earth.

The crew includes NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian astronaut Jeremy Hansen. The mission is expected to test critical systems such as life support, navigation, and the spacecraft’s heat shield in deep space conditions.

Unlike future Artemis missions, Artemis II will not land on the lunar surface. Instead, it serves as a crucial step toward upcoming missions that aim to establish a sustained human presence on the Moon and eventually enable crewed missions to Mars.

NASA officials say the mission represents a major milestone in space exploration, combining international collaboration and advanced technology to usher in a new era of human spaceflight.

Scientists map magnetic fields in molecular clouds near the Milky Way, revealing their key role in slowing and shaping star formation.

Scientists have uncovered new insights into how stars are formed by mapping the magnetic fields surrounding molecular clouds near the Milky Way’s disc, offering a deeper understanding of one of the universe’s most fundamental processes.

The study focuses on two small molecular clouds—L1604 and L121—revealing how magnetic fields influence the balance between gravity and internal pressure during star formation.

Magnetic Fields Star Formation in Milky Way Clouds

For decades, astronomers have understood star formation as a balance between gravity pulling gas inward and internal pressure pushing outward. However, the new research highlights a third critical factor: magnetic fields.

In a media statement, the researchers explained that magnetic fields act as an invisible force shaping how molecular clouds evolve and collapse to form stars.

The study was conducted by scientists from the Aryabhatta Research Institute of Observational Sciences (ARIES)m Uttarakhand, India and Assam University, using advanced polarimetric techniques to detect otherwise invisible magnetic structures.

Magnetic Fields Star Formation Observed Using Polarimetry

To map these fields, the team used R-band polarimetry with the ARIES Imaging Polarimeter mounted on a 104-cm telescope in Nainital.

This technique measures how starlight becomes polarised as it passes through dust grains aligned by magnetic fields.

In a media statement, the researchers said that by analysing thousands of such light signals, they were able to “see” the skeleton of magnetic fields surrounding the molecular clouds for the first time.

Two Molecular Clouds Reveal Contrasting Behaviour

The study examined two distinct clouds:

  • L1604, located about 816 parsecs away, is dense and massive, with strong potential for future star formation
  • L121, much closer at 124 parsecs, is less dense but exhibits a stronger and more organised magnetic field

In a media statement, the scientists noted that the orderly magnetic structure in L121 suggests it has not yet undergone intense gravitational collapse, unlike more active star-forming regions.

Magnetic Fields Star Formation Controlled by Energy Balance

By calculating magnetic field strength, the researchers found that both clouds are sub-critical, meaning magnetic forces are strong enough to resist gravitational collapse across most of their structure.

In a media statement, the team stated that magnetic energy dominates over both turbulence and gravity at the outer regions of the clouds.

However, deep within the dense cores, gravity may begin to take over, creating conditions suitable for star formation.

The “Recipe” for Star Formation

The findings suggest that magnetic fields play a crucial role in regulating how quickly stars form.

In a media statement, researchers said that magnetism acts as an “invisible hand,” slowing down star formation and preventing galaxies from converting all their gas into stars at once.

The study positions L1604 and L121 as natural laboratories for understanding the interplay between gravity and magnetism.

Rather than being passive clouds, they represent dynamic systems where fundamental forces interact over millions of years to shape the birth of stars.

The findings offer a clearer picture of how galaxies like the Milky Way sustain star formation over long cosmic timescales, balancing collapse with control.

Researchers Use AI to Enable Robots to ‘See’ Through Walls

Researchers at Massachusetts Institute of Technology have developed a new artificial intelligence-powered system that allows robots to detect and reconstruct objects hidden behind walls and obstacles, marking a significant breakthrough in machine perception.

The system combines wireless signals with generative AI models to enable what researchers describe as a new form of “wireless vision,” potentially transforming robotics, logistics, and smart environments.

AI See Through Walls Using Wireless Signals

The research builds on over a decade of work using millimeter wave (mmWave) signals—similar to those used in Wi-Fi—which can pass through materials such as drywall, plastic, and cardboard and reflect off hidden objects.

Earlier approaches could only capture partial shapes due to limitations in how these signals reflect.

The new system overcomes this by combining wireless reflections with generative AI, enabling the reconstruction of complete object shapes even when they are not directly visible.

“What we’ve done now is develop generative AI models that help us understand wireless reflections. This opens up a lot of interesting new applications, but technically it is also a qualitative leap in capabilities, from being able to fill in gaps we were not able to see before to being able to interpret reflections and reconstruct entire scenes,” said Fadel Adib, in a media statement.

“We are using AI to finally unlock wireless vision.”

AI See Through Walls Improves Object Reconstruction

The system, called Wave-Former, first creates a partial image of a hidden object using reflected wireless signals. It then uses a trained AI model to fill in missing parts and refine the reconstruction.

In tests, Wave-Former successfully reconstructed around 70 everyday objects—including boxes, utensils, and fruits—with nearly 20% higher accuracy than existing methods.

The objects were placed behind or under materials such as wood, fabric, and plastic, demonstrating the system’s robustness in real-world conditions.

AI See Through Walls Reconstructs Entire Rooms

Beyond individual objects, the researchers developed a second system capable of reconstructing entire indoor environments.

Using a single stationary radar, the system tracks how wireless signals bounce off moving humans and surrounding objects. These reflections—often considered noise—are analysed by AI to map out the room layout.

The system, known as RISE, was tested using over 100 human movement patterns and achieved twice the accuracy of existing techniques in reconstructing indoor spaces.

Privacy-Preserving Alternative to Cameras

Unlike camera-based systems, this approach does not capture visual images, offering a privacy-preserving alternative for indoor monitoring and robotics.

Because it relies on wireless signals rather than cameras, it can detect presence and layout without revealing identifiable details.

Applications in Warehousing and Smart Homes

The researchers say the technology could have wide-ranging applications:

  • Warehouses: Robots could verify packed items before shipping, reducing errors and returns
  • Smart homes: Robots could better understand human location and movement
  • Human-robot interaction: Improved safety and efficiency in shared environments

The system could also pave the way for future “foundation models” trained specifically on wireless data, similar to how large AI models are trained for language and vision.
