Millimeter Waves Reveal Nanoscale Material Secrets
![Silicon photonic crystal cavities exploit subtle shifts in resonant frequency-and linewidth, transitioning from [latex]\kappa_i[/latex] to [latex]\kappa_i'[/latex]-to sense the presence of a sample introduced within the cavity, maximizing perturbative response by positioning the sample at an electric field antinode within the 18.74 mm device, thereby establishing a sensitive relationship between cavity characteristics and material properties.](https://arxiv.org/html/2602.17527v1/x1.png)
A new silicon-based photonic crystal cavity enables highly sensitive, frequency-domain detection of nanoscale material properties at cryogenic temperatures.
Talking Point: What Are You Playing This Weekend? – Issue 621
I’m working on my New Year’s goal to play twelve PlayStation 5 games that weren’t released on the PS4, and for February, I’ve chosen Deathloop, developed by Arkane Studios.
Casualty pulled from screens tonight in BBC One schedule shake-up
The soap is taking somewhat of a mid-series break, to accommodate sports coverage by the channel.
The BAFTAs are too conventional – and Urchin’s snub is the perfect illustration
All five films nominated for the BAFTA Best Film award in 2026 are also contenders for the Oscars’ Best Picture award – a trend that’s held true for the last decade, with only a couple of exceptions (I, Daniel Blake in 2017 and The Mauritanian in 2020).
Beyond the Luttinger Liquid: New States of Matter Emerge in 1D Bose Gases
Researchers have discovered exotic critical states resembling ‘fractional Fermi seas’ within one-dimensional Bose gases pushed far from equilibrium, challenging conventional models of quantum fluids.
Altcoins Dance on Bitcoin’s Grave: Is the Crypto Waltz Beginning?
What provoked this sudden ballet? None other than the U.S. Supreme Court, which, in a 6-3 ruling, declared President Trump’s global tariffs as illegal. Traders, ever the pessimists, braced for a sell-off. Instead, capital leapt from Bitcoin’s arms into the waiting embrace of altcoins. Oh, the irony! The market, it seems, has a sense of humor darker than a Moscow winter.

She will develop, write, executive produce, and direct new TV series for them. This move means she’s stepping away from Marvel Studios for the time being, according to Variety.
Ethereum’s $2K Gamble: Bull Trap or Breakout?
Ethereum’s [ETH] technical setup is a riddle wrapped in a paradox. After a 50% drop from its mid-January peak, the price lingers near $2k, a crossroads where hope and despair collide. One might say it’s a trap, but then again, what is life if not a series of traps, each more elaborate than the last?
