Antimatter Antihydrogen Atoms Trap Matter Positrons
- CERN's ALPHA collaboration has pulled off a stunning breakthrough. Trapping antimatter is kind of like trying to catch snowflakes with a frying pan — if the snowflakes wanted to blow up the pan every time they touched it. That's basically the daily grind for CERN physicists who study antihydrogen. For years, they've been capturing these fragile anti-atoms one by one, inching toward answers about one of the universe's biggest mysteries. Now, they've made a major leap. The ALPHA ...

Particles Higgs Boson Beams Particle Times Protons
- Every time two beams of particles collide inside an accelerator, the universe lets us in on a little secret. Sometimes it's a particle no one has ever seen. Other times, it's a fleeting glimpse of conditions that last existed in the first moments after the Big Bang. A particle accelerator is the machine that makes those collisions possible. Its job is straightforward to describe: Take tiny charged particles and drive them to extreme speeds so the resulting collisions carry enough force to break ... [Read More]

Quantum Quantum Internet Photons Information Dots Quantum Dot
- Scientists link two distant quantum dots, teleporting information between their photons for the first time. Every message we send online, whether a bank transfer or a meme, relies on light. Tiny pulses travel through fiber-optic cables, bouncing between nodes that amplify the signal every few dozen kilometers. Your internet might come from your wireless carrier or WiFI, but broadband's backbone is still fiber-optic cables. But the quantum internet of the future — an ultra-secure network ... [Read More]

A new dual-light microscope lets researchers observe micro- and nanoscale activity inside living cells without using dyes. The system, from the University of Tokyo, captures both detailed structures and tiny moving particles at once, providing a more complete view of cellular behaviour. The technology is in the form of a microscope capable of detecting signals across an intensity range fourteen times ... [Read More]


Bessy Ii Oxide Superconductivity Layers Temperature Alexander F Ouml Hlisch
- High-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to a better understanding of high-temperature superconductivity and could also be relevant ... [Read More]

- Follow Earth on Google A team led by MIT used a simple molecule to peek inside a radium atom's nucleus. In a new study, they watched electrons in radium monofluoride pick up a tiny energy change that betrays what is happening deep in the core. The tests ran on a compact setup at CERN in Switzerland and not in a collider that stretches for miles. The result points to a practical way to map nuclear structure and to probe why the universe favors matter over antimatter. Radium monofluoride reveals ... [Read More]

Germanium Crystal Superconductivity Scientists Materials Structure
- Scientists have long sought to make semiconductors—vital components in computer chips and solar cells—that are also superconducting, thereby enhancing their speed and energy efficiency and enabling new quantum technologies. However, achieving superconductivity in semiconductor materials such as silicon and germanium has proved challenging due to difficulty in maintaining an optimal atomic structure with the desired conduction behavior. In a paper published in the journal Nature ... [Read More]

Carbon Llccs Swcnws Diameter Prof Maruyama Polyyne
- Carbynes, or long linear carbon chains (LLCCs), have received significant attention in recent years due to their predicted exceptional properties. However, experimentally, their properties have been hard to probe due to their low stability. To improve stability, it is necessary to encapsulate LLCCs in small diameter carbon nanotubes (CNTs). Now, researchers have developed a new method to synthesize small diameter single-walled carbon nanowires (SWCNWs), featuring high-density LLCCs encapsulated ... [Read More]

Quantum Gravity Field Theory Howl Entanglement
- The nature of gravity — and whether it can be reconciled with quantum mechanics — is one of the biggest mysteries in physics. Most researchers think that at a fundamental level, all phenomena follow the principles of quantum physics, but those principles do not seem to be compatible with the accepted theory of gravity. For years, researchers have been proposing experiments to show whether gravity could produce a phenomenon known as quantum entanglement. Now, two theoretical ... [Read More]

Matter Vortices Dark Matter Halos Dynamics Patrick Valageas
- The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly Interacting Massive Particles, with masses of around 100 GeV/c 2 ), primordial black holes, and ultralight axion-like particles (mass of 10 -22 to 1 eV/c 2 ). In the latter case, dark matter behaves like a wave, described by a Schrödinger equation, rather than as a collection of point particles. ... [Read More]
