Bitcoin price news: BTC slips below $88,000, but Strategy, Circle, Gemini among those sharply lower

Digital asset treasury companies — the year's worst performers — were also hardest hit on Tuesday.

Bitcoin led crypto markets lower Tuesday, down by about 1% over the past 24 hours to just below $88,000. The decline came even as gold, silver and copper all surged to record highs (though have pulled back a bit in Tuesday afternoon trade). U.S. stocks are ahead modestly, the Nasdaq gaining 0.45%.

Scientists Confirm the Incredible Existence of ‘Second Sound’

Here’s visible proof for the first time ever.

In the world of average, everyday materials, heat tends to spread out from a localized source. Drop a burning coal into a pot of water, and that liquid will slowly rise in temperature before its heat eventually dissipates. But the world is full of rare, exotic materials that don’t exactly play by these thermal rules.

Scientists Used a Diamond to Create a New Phase of Matter

The researchers are confident that this process can be applied to other material beyond diamonds as well.

Since their theoretical discovery in 2012, time crystals have been front-and-center in conversations about how to improve quantum computers. While diamond, ice, and any other solid you can think of has a crystal lattice structure that repeats in space (another name for them could be “space crystals”), time crystals, as their name suggests, oscillate in perpetual cycles across time. These crystals, the thinking goes, could form stable forms of quantum memory and error-free quantum circuits, drastically improving a quantum computer’s performance.

Repeated environmental changes can lead evolution in unexpected directions, and research from Vermont shows that studying a single population does not capture the full story of an entire species. All forms of life exist in environments that are constantly shifting. Seasons change, wet years follow dry ones, and conditions that once favored survival can quickly disappear. Because of this, it is clear that plant and animal populations are continually forced to adapt, says University of Vermont scientist Csenge Petak. What remains uncertain is how these ongoing environmental changes influence the course of evolution itself.

From Gold To Bitcoin: What Investors Get Wrong About Value Storage https://www.forbes.com/sites/digital-assets/2025/12/18/from-gold-to-bitcoin-what-investors-get-wrong-about-value-storage/ For centuries, gold was the benchmark for storing value: scarce, physical, and trusted. But in a digitized world where capital moves across borders in seconds, gold’s physicality has become a limitation. Bitcoin offers a modern alternative: scarce by design, instantly transferable, and secured by code rather than vaults. It offers a new baseline: a form of “hard money” fit for the 21st century, accessible to anyone with a digital wallet, not only those with vaults or access to bullion markets.

Scientists Designed a Warp Drive That Theoretically Works With Real Physics

A new study shows that warp metrics can fit Star Trek-esque starship designs.

While living in his dorm at the University of Cardiff, Wales, Mexican physicist Miguel Alcubierre—then pursuing a Ph.D. in numerical relativity—wrote a short paper detailing the physical reality of the warp drive. Alcubierre often spent Friday nights with friends watching Star Trek: The Next Generation, and one night, he pondered how exactly such an engine could work. Eventually published in 1994, the young physicist couldn’t have known that the resulting paper would inspire decades of research into the real-world applications of warp drives.
