7. Making light 'feel' a magnetic field like an electron wouldСр, 24 апр[-/+]Категория(?) Unlike electrons, particles of light are uncharged, so they do not respond to magnetic fields.

11. How light can vaporize water without the need for heatВт, 23 апр[-/+]Категория(?) It's the most fundamental of processes—the evaporation of water from the surfaces of oceans and lakes, the burning off of fog in the morning sun, and the drying of briny ponds that leaves solid salt behind. Evaporation is all around us, and humans have been observing it and making use of it for as long as we have existed. Медиа: image / jpg | ↑ |
13. CMS Collaboration observes new all-heavy quark structuresВт, 23 апр[-/+]Категория(?) For over a decade, the CMS Collaboration, a large team of researchers based at different institutes worldwide, has been analyzing data collected at the Compact Muon Solenoid, a general-purpose particle detector at CERN's Large Hadron Collider (LHC). This large-scale international scientific collaboration has been trying to observe various elusive physical phenomena, including exotic particles and dark matter candidates. Медиа: image / jpg | ↑ |
16. Record electron temperatures for a small-scale, sheared-flow-stabilized Z-pinch fusion device achievedВт, 23 апр[-/+]Категория(?) In the nine decades since humans first produced fusion reactions, only a few fusion technologies have demonstrated the ability to make a thermal fusion plasma with electron temperatures hotter than 10 million degrees Celsius, roughly the temperature of the core of the sun. Zap Energy's unique approach, known as a sheared-flow-stabilized Z pinch, has now joined those rarefied ranks, far exceeding this plasma temperature milestone in a device that is a fraction of the scale of other fusion systems.

Researchers at Tohoku University and the Japan Atomic Energy Agency have developed fundamental experiments and theories to manipulate the geometry of the "electron universe," which describes the structure of electronic quantum states in a manner mathematically similar to the actual universe, within a magnetic material under ambient conditions.

26. Study shows ultra-thin two-dimensional materials can rotate the polarization of visible lightПн, 22 апр[-/+]Категория(?) It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave when the light passes through the material. This property is utilized in a central component of optical communication networks known as an "optical isolator" or "optical diode." This component allows light to propagate in one direction but blocks all light in the other direction. Медиа: image / jpg | ↑ |
28. Beta-decay measurements in mirror nuclei pin down the weak nuclear forceПн, 22 апр[-/+]Категория(?) The Standard Model of Particle Physics is scientists' best understanding of the forces that describe how subatomic particles interact. The Standard Model encompasses four forces: the strong nuclear force, the weak nuclear force, the electromagnetic force, and the gravitational force. All four forces govern the way our universe works. However, the weak nuclear force is exceptionally difficult to study as it is overshadowed by the much greater effects of the strong nuclear and electromagnetic forces. Медиа: image / jpg | ↑ |
30. Springing simulations forward with quantum computingПн, 22 апр[-/+]Категория(?) Though "coupled oscillations" may not sound familiar, they are everywhere in nature. The term "coupled harmonic oscillators" describes interacting systems of masses and springs, but their utility in science and engineering does not end there. They describe mechanical systems like bridges, the bonds between atoms, and even gravitational tidal effects between the Earth and the moon. Understanding such problems allows us to probe a correspondingly huge range of systems from chemistry to engineering to materials science and beyond. Медиа: image / jpg | ↑ |
