Bitcoin's Pullback Spurs Year-End Crypto Tax-Loss Harvesting https://finance.yahoo.com/news/bitcoins-pullback-spurs-end-crypto-160023149.html Bitcoin (BTC-USD) is entering the final stretch of the year under pressure, with a roughly 30% slide from its all-time high creating conditions advisers say could be driving heavier tax-loss harvesting than in prior years. While Bitcoin is down about 5% year-to-date, the S&P 500 (SPY) has risen roughly 18% over the same period, a divergence that advisers say is encouraging investors to sell underwater crypto positions to potentially offset equity gains before Dec. 31, particularly for purchases made near October's peak. Some advisers note that tax-loss harvesting in crypto is increasingly being treated as part of a broader portfolio-wide tax strategy rather than a standalone trade. https://stacker.news/items/1388655

Atomtronics: Quantum Technology's Future With Unprecedented Control & Precision https://quantumzeitgeist.com/atomtronics-the-future-of-quantum-technology-with-unprecedented-control-and-precision/ Atomtronics, a burgeoning field within quantum science and technology, involves the manipulation of ultracold atoms in matter wave circuits, allowing for precise control over a range of physical configurations. Atomtronic devices, such as the atomtronic quantum interference device (AQUID), emulate known electronic components like diodes, batteries, and transistors. Quantum superposition is a key component in atomtronics, used to create atomic qubits. Atomtronics has potential applications in emulating superconducting circuit elements. Research by H M Cataldo from the Universidad de Buenos Aires provides insights into the quantum features of stationary states, paving the way for the development and control of atomtronic devices. https://stacker.news/items/1388438

Taiwan rattled by 7.0 magnitude quake, no major damage reported https://www.cnn.com/2025/12/27/asia/taiwan-earthquake-tremors-intl-latam A 7.0 magnitude earthquake struck some 32 km (20 miles) off Taiwan’s northeastern coastal city of Yilan on Saturday, the island’s weather administration said, with no immediate reports of major damage. The quake with a depth of 73 km (45 miles) was felt across Taiwan and shook buildings in the capital Taipei, the administration said, assigning it an intensity-four category meaning there could be minor damage. https://stacker.news/items/1384968

Zelensky heads to US for Trump peace talks after Kyiv hit by strikes https://www.bbc.com/news/live/c7732j0jvnnt When they meet in Florida on Sunday, it's expected Trump and Zelensky will discuss a 20-point proposal to end the war. It's an updated take on an earlier 28-point version, which had been drawn up between US envoy Steve Witkoff and Russian negotiators. https://stacker.news/items/1382976

Why Some Physicists Think We Are Living Inside A Black Hole https://www.iflscience.com/why-some-physicists-think-we-are-living-inside-a-black-hole-82039 In an attempt to reconcile some of the paradoxes discovered when studying them, physicists have proposed stranger hypotheses still, with one suggesting that they imply we live in a holographic universe, where all of what we see and perceive is in fact encoded at our universe's boundary, a 3D (plus time) representation of a two-dimensional (plus time) universe. Further than that, some have suggested that it could imply that our universe is within a black hole of a larger universe. https://stacker.news/items/1382452

Ukrainian capital Kyiv under massive Russian attack, officials say https://www.reuters.com/world/europe/ukrainian-capital-kyiv-under-massive-russian-attack-officials-say-2025-12-27/ The Ukrainian capital Kyiv came under a massive Russian attack early on Saturday, with explosions sounding in the city, air defences in operation and the Ukrainian military saying missiles were being deployed. The Russian action took place two days before a meeting Ukrainian President Volodymyr Zelenskiy says he is due to hold in the United States with President Donald Trump to work out details of an accord for settling the nearly four-year-old war pitting Russia against Ukraine. https://stacker.news/items/1382080

Gold knocks on a 50-year closed door as BTC price faces a defining support test https://www.coindesk.com/markets/2025/12/24/gold-knocks-on-a-door-that-s-been-shut-for-50-years-as-bitcoin-tests-a-defining-support Gold is at a critical juncture when measured against U.S. money supply (M2SL), testing a level it last reached in 2011 and not surpassed since the 1970s, when the price more than tripled to a then-record $700 an ounce over the course of several years. In contrast, Bitcoin, referred to by some supporters as digital gold, has dropped toward a support level, revisiting lows it last touched during the "tariff tantrum" in April. https://stacker.news/items/1379974

Dark Matter Breakthrough: Physicists Crack “Big Bang Theory” Puzzle https://scitechdaily.com/dark-matter-breakthrough-physicists-crack-big-bang-theory-puzzle/ A new theoretical study suggests fusion reactors could do more than generate energy, they might also produce particles linked to dark matter. Researchers at the University of Cincinnati say they have worked out, at least on paper, how fusion reactors could produce subatomic particles known as axions, a challenge that stumped two of America’s most famous fictional physicists. In the CBS sitcom “The Big Bang Theory,” particle physicists Sheldon Cooper and Leonard Hofstadter, who share an apartment, grapple with the same idea across three episodes in Season 5 but never solve it. https://stacker.news/items/1379588

Zelensky says he plans to meet Trump in Florida for peace talks Sunday https://www.cnn.com/2025/12/26/europe/zelensky-trump-talks-ukraine-russia-intl Ukrainian President Volodymyr Zelensky said he plans to meet his US counterpart Donald Trump in Florida Sunday, as part of efforts to reach a peace deal to end Russia’s nearly four-year war in Ukraine. Speaking to reporters Friday, Zelensky cautioned that he could not say whether the meeting would lead to a firm agreement, but said the two sides would aim to “finalize as much as we can.” Earlier on Friday, the Ukrainian leader had struck an optimistic note, writing on X that “a lot can be decided before the New Year.” https://stacker.news/items/1379097
