Quantum technologies promise secure communication networks, powerful forms of computing and new sensing tools. One of the major challenges, however, is that different quantum systems often operate at different wavelengths of light. Quantum memories, trapped ions and other quantum devices may work best in the ultraviolet or visible range, while long-distance communication over optical fibers […] Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded joint in polyethylene pipe can be just as strong as the pipe itself, if not stronger. However, the reason for this strength has remained a mystery. Go […] Despite all the advertisements for engagement rings and necklace gifts, natural diamonds are imperfect. Their carbon atoms are arranged in a cubic lattice, but they nonetheless contain several types of crystallographic defects due to impurities that occasionally replace a carbon atom. The most common types of impurities are nitrogen and boron; “Type I” diamonds contain […] Electrons, particles that carry a negative electric charge, typically move through materials. At low densities and temperatures, however, the electrical repulsion between them can overpower their tendency to move, prompting them to arrange themselves into ordered patterns known as Wigner crystals. Go to Source An AI assistant helped University of Colorado Boulder researchers solve a mathematical problem that had challenged their lab for a year and a half, though it made subtle errors along the way. The breakthrough could improve how scientists study nanoparticles—tiny particles about 1,000 times thinner than a human hair—but it reveals both the promise and […] Finding one Higgs boson was hard enough, but physicists at the Large Hadron Collider (LHC) are hunting for something even more elusive: pairs of Higgs bosons. At the recent International Conference on High Energy Physics 2026, the ATLAS and CMS collaborations presented new constraints on the double-Higgs production rate, providing insight into how the Higgs […] When an athlete swings upside down atop a 7-meter (23-foot) pendulum, it may seem like a feat of strength, courage or technique. A new study suggests it is something more fundamental: a striking demonstration of how intelligence emerges from the interaction of brain, body and environment. Go to Source Table tennis professionals are true masters at redirecting fast-moving projectiles. Putting a targeted spin on a serve can make the little white ball fly straight toward the edge of the table but then, at the last moment, take a sharp curve into the left corner. The physical phenomenon behind this sporting trick is known as […] In the hunt for one of nature’s most elusive substances—dark matter, which makes up 85% of all matter in the universe—scientists are going to extremes. Deep underground and chilled to near absolute zero, the Super Cryogenic Dark Matter Search (SuperCDMS) SNOLAB—one of the world’s most sensitive dark matter searches—has begun collecting its first scientific data. […] High-energy nuclear collisions recreate extreme conditions similar to those in the early universe, producing quark–gluon plasma (QGP), a hot state of matter in which quarks and gluons are no longer confined inside protons and neutrons. While large systems such as lead–lead collisions can produce matter that behaves like a fluid, collective behavior has also been […] When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning surfaces. Go to Source Physics is most readily applied to relatively simple systems: a pendulum, two electrons colliding or the structure of the solar system. But when systems become complicated—when many particles interact with one another, in condensed matter systems such as gases and fluids or in the cosmology of the early universe—simplifications can be made using a technique […] A team of researchers from the University of Bonn, Heidelberg University and the National Autonomous University of Mexico has studied the critical behavior of light particles (photons) close to a phase transition. This critical scaling behavior, which sees thermodynamic quantities grow extremely large or diverge shortly prior to Bose-Einstein condensation, had never before been seen […] While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage Group at the […] Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted is determined by the vibration of the atoms that constitute a material, but it is not easy to directly examine, at the atomic scale, how […] |
