Tectonic plates do the same, sliding across each other until they stick in a stationary state. Everything from the tiniest particles to unfathomably large landmasses possesses this fundamental stick and slip characteristic, but only now are scientists beginning to understand the mechanics of the friction underpinning this property. /news/2025-06-simple-smooth-friction-mystery.html General 糖心视频ics Mon, 23 Jun 2025 14:06:03 EDT news669906361 The ongoing search for dark matter, the elusive type of matter that does not emit, absorb or reflect light and is estimated to account for most of the universe's mass, has not yet yielded conclusive results. Axions, hypothetical elementary particles that were first theorized about in the 1970s, are among the most promising candidates for dark matter. /news/2025-06-axions-ray-entire-galaxies.html Astronomy Mon, 09 Jun 2025 09:20:01 EDT news668679021 Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun.

This state, called a quark-gluon plasma, existed for a brief time until the temperature dropped to about 20 trillion Kelvin, after which this "hadronization" took place. /news/2025-05-thermodynamic-properties-quark-gluon-plasma.html General 糖心视频ics Plasma 糖心视频ics Fri, 30 May 2025 10:00:03 EDT news667816855 The moon's nearside (that is, the side facing Earth) is dark-colored and dominated by ancient lava flows, whereas the farside is more rugged鈥攁nd NASA researchers now suggest it's due to a wonky lunar interior. Using data from twin spacecraft named Ebb and Flow, they found a 2鈥�3% difference in the moon mantle's ability to deform on each side. They say this data could be explained by the nearest hemisphere's insides being up to 170掳C hotter than the farside. /news/2025-05-twin-spacecraft-mission-reveals-hot.html Planetary Sciences Sat, 17 May 2025 10:20:01 EDT news666447144 In a landmark achievement for fusion energy, ITER has completed all components for the world's largest, most powerful pulsed superconducting electromagnet system. /news/2025-04-international-collaboration-world-largest-powerful.html Plasma 糖心视频ics Wed, 30 Apr 2025 11:30:01 EDT news665053898 Using artificial intelligence shortens the time to identify complex quantum phases in materials from months to minutes, finds a new study published in Newton.

In its most familiar application, it enables powerful magnets in MRI machines to create the magnetic fields that allow doctors to see inside our bodies. Thus far, materials can only achieve superconductivity at extremely low temperatures, near absolute zero (a few tens of Kelvin or colder). /news/2025-03-superconducting-state-cooper-pair-density.html Superconductivity Thu, 27 Mar 2025 17:00:04 EDT news662313602 Professor Ariando and Dr. Stephen Lin Er Chow from the National University of Singapore (NUS) Department of 糖心视频ics have designed and synthesized a groundbreaking new material鈥攁 copper-free superconducting oxide鈥攃apable of superconducting at approximately 40 Kelvin (K), or about minus 233掳C, under ambient pressure. /news/2025-03-physicists-copper-free-high-temperature.html Superconductivity Thu, 27 Mar 2025 08:57:04 EDT news662284621 In recent years, some large physics experiments worldwide have been trying to gather evidence of a nuclear process known as neutrinoless double beta (0谓尾尾) decay. This is a rare process that entails the simultaneous decay of two neutrons in a nucleus into two protons, without resulting in the emission of neutrinos, which is instead associated with standard double beta decay. /news/2025-03-amore-limits-neutrinoless-beta-decay.html General 糖心视频ics Sun, 23 Mar 2025 09:30:02 EDT news661774901 Ice may be present a few centimeters below the moon's surface in more areas of the lunar polar regions than was previously thought due to large, yet highly localized, variations in surface temperatures. The results, published in Communications Earth & Environment, are derived from direct measurements taken at the lunar surface in 2023 by the Indian Chandrayaan-3 mission. /news/2025-03-potential-ice-moon.html Space Exploration Planetary Sciences Thu, 06 Mar 2025 11:00:03 EST news660472502 When atoms collide, their exact structure鈥攆or example, the number of electrons they have or even the quantum spin of their nuclei鈥攈as a lot to say about how they bounce off each other. This is especially true for atoms cooled to near-zero Kelvin, where quantum mechanical effects give rise to unexpected phenomena. Collisions of these cold atoms can sometimes be caused by incoming laser light, resulting in the colliding atom-pair forming a short-lived molecular state before disassociating and releasing an enormous amount of energy. /news/2025-02-quantum-billiard-balls-deeper-atomic.html General 糖心视频ics Quantum 糖心视频ics Tue, 18 Feb 2025 16:35:05 EST news659118901 Water is ubiquitous and seemingly ordinary, possessing no distinct color or odor. Though we often take water for granted, it is by no means a simple substance. As a consequence of its chemical properties, H鈧侽 is one of the most incredible substances, able to form into 20 known separate crystalline ice phases.

Determining how iron behaves in these extreme conditions could thus help to advance the current understanding of our home planet's structure and geodynamics. /news/2025-01-temperature-phase-stability-iron-core.html Earth Sciences Tue, 21 Jan 2025 13:29:05 EST news656688538 For now, the future of life on Earth is in human hands. But after the anthropocentric era, the situation starts to get dicey. The sun's luminosity is increasing over time, about 1% every 110 million years, so the Earth's surface will gradually get warmer (but at a vastly slower rate than today's global warming). /news/2024-12-future-lifespan.html Planetary Sciences Tue, 31 Dec 2024 09:00:01 EST news654771336 Much of the mass in the universe lies not in stars or galaxies, but in the space between them, known as the intergalactic medium. It is warm and even hot, and is called the "warm-hot intergalactic medium," or WHIM. It holds about 50% of the normal mass (viz. baryonic, not including dark matter) of the universe but with a density of hydrogen ions less than 100 per cubic meter. /news/2024-11-quantification-intergalactic-medium-cosmic-filaments.html Astronomy Wed, 27 Nov 2024 12:20:01 EST news651930701 Diamond rain?

At its peak, FU Ori was intrinsically 100 times brighter than our sun. Unlike an exploding star, though, it has declined in luminosity only languidly since then. /news/2024-11-hubble-sizzling-young-star-fu.html Astronomy Thu, 21 Nov 2024 16:40:57 EST news651429646 Have you ever wondered how long it took our sun to form in its stellar nursery?
