New ‘Fire-and-Ice’ Phase of Matter Discovered in a Magnet

Credit: PixabayA newly discovered state of matter has emerged within a previously identified exotic phase in a magnetic compound.In 2016, physicists Weiguo Yin, Christopher Roth, and Alexei Tsvelik from Brookhaven National Laboratory identified a unique "half-fire, half-ice" spin-state phase in Sr₃CuIrO₆, a compound of strontium, copper, iridium, and oxygen. Now, they have uncovered its...

Researchers Challenge Their Own Findings by Generating Power From Earth’s Rotation

Credit: PixabayResearchers harness tiny voltage from Earth's rotation, revealing a potential new energy source.The foundation for this research dates back to 2016 when Princeton astrophysicist Christopher Chyba and JPL planetary scientist Kevin Hand initially argued that such energy generation was impossible. However, as they revisited their own conclusions, they began to question the assumptions...

Quantum “Tornadoes” in Semimetal Could Revolutionize Electronics

Model of a quantum tornado in momentum space. (think-design/Jochen Thamm)Physicists in Germany have demonstrated that electron inertia can create "tornadoes" inside a quantum semimetal, revealing a new layer of complexity in electron motion.Electrons rarely stay still, and their movements can take unexpected forms. In tantalum arsenide, a quantum material, researchers found that electrons form vortices—not...

Physicists Develop Lab-Grown Diamond Tougher Than Natural Ones

Credit: PixabayScientists have once again created a synthetic diamond even tougher than natural ones, using a novel approach to diamond formation.By subjecting graphite—a super-hard material in its own right—to extreme pressure and heating it to 1,800 K (1,527 °C or 2,780 °F), the researchers produced a diamond with a hexagonal lattice structure instead of...

New Measurements of Double Magic Atom Reveal Surprise

An illustration of the structure of an atom. (KTSDesign/SciencePhotoLibrary/Getty Images)An experiment involving the collision of specialized lead atoms with high-speed particles has revealed an astonishing finding.Rather than the expected perfect spherical shape, the core of the isotope known as lead-208 (208Pb) appears unexpectedly flattened.The Surprising Results of the Experiment on Lead-208This discovery indicates that atomic...

Measurements of a ‘Double Magic’ Atom Uncover an Unexpected Discovery

Credit: PixabayA groundbreaking experiment smashing special lead atoms with high-speed particles has revealed an unexpected twist in nuclear physics.Physicists from the University of Surrey expected lead-208 (208Pb) to have a perfectly spherical nucleus. Instead, their findings showed a slightly flattened shape, challenging long-held assumptions about atomic structure.A Puzzle at the Heart of Nuclear Physics208Pb...

We’ve Misunderstood a Fundamental Law of Physics for Nearly 300 Years

Credit: PixabayWhen Isaac Newton penned his famous laws of motion in 1687, he likely never imagined they would still spark debate over 300 years later. Writing in Latin, he outlined three fundamental principles governing motion in the universe. Over the centuries, scholars have translated, analyzed, and debated them extensively.However, philosopher of language and mathematics...

Magnetism Has Just Solved One of Quantum Tech’s Biggest Challenges

Credit: PixabayResearchers have found a way to preserve quantum properties in 3D materials using magnetic confinement. By stabilizing excitons—energy-carrying quasiparticles—through the magnetic properties of chromium sulfide bromide, they address a major challenge in quantum technology.Quantum effects typically only work at small scales, making them hard to apply in real-world systems like quantum computers. However,...

Quantum Search for the Origin of Time Reveals No Distinction Between Past and Future

Credit: PixabayIn search of the source of time, University of Surrey physicists Thomas Guff, Chintalpati Umashankar Shastry, and Andrea Rocco examined what they likened to a hot quantum bathtub beneath the endless stretch of eternity.No matter how hard we try, we can't remember what will happen tomorrow—and physicists still don't know why.They didn't find...

Scientists Uncover a New Type of Quantum State in Graphene

Credit: PixabayElectrons forced through a maze of twisted carbon layers behave in unexpected ways. Researchers from the University of British Columbia, the University of Washington, Johns Hopkins University, and Japan’s National Institute for Materials Science have discovered a strange new state of matter in graphene’s electrical currents.Their findings confirm predictions about electron behavior in...
