If you've watched a YouTube video in the last few years, you know this is going to work. 😂 Who isn't holding their microphone these days? https://www.threads.com/@chriswelch/post/DOvmOquDkIa

Nothing's Ear 3 earbuds add some metal flair to the company's signature transparent look. But their biggest new trick is the ability to use the charging case as a microphone for clearer voice calls. ...Is that something you'd do? https://www.bloomberg.com/news/articles/2025-09-18/nothing-debuts-179-ear-3-earbuds-with-microphone-in-the-charging-case?srnd=phx-technology

Jagd auf Mikroplastik: Französische Wissenschaftler schlagen Alarm wegen Plastikverschmutzung
Wir essen, atmen und trinken es, aber wir wissen noch immer nicht alles darüber. Wir sprechen über Mikroplastik. Es ist gefährlich für die Umwelt und für unsere Gesundheit. Es kann giftige Substanzen aufnehmen und sich leicht in die Nahrungskette einnisten. Was tut die Europäische Union dagegen? #EuropeansStories

Coupling 4H-Silicon Carbide spins to a microwave resonator at milli-Kelvin temperature
Coupling microwave cavity modes with spin qubit transitions is crucial for enabling efficient qubit readout and control, long-distance qubit coupling, quantum memory implementation, and entanglement generation. We experimentally observe the coupling of different spin qubit transitions in Silicon Carbide (SiC) material to a 3D microwave (MW resonator mode around 12.6~GHz at a temperature of 10~mK. Tuning the spin resonances across the cavity resonance via magnetic-field sweeps, we perform MW cav…

Measurable one-ended spanning trees
We show that a one-ended, locally finite, measurable graph on a standard probability space admits a measurable one-ended spanning subtree if and only if it is measure-hyperfinite. This answers a question posed by Bowen, Poulin, and Zomback and extends recent results of Timár and Conley, Gaboriau, Marks, and Tucker-Drob.

There's another season of "Made in Abyss" on Netflix!
The show was an incredible bait and switch. It had this cutesy look and a very interesting world to explore. But each episode got darker end the end of season 1 was pure body horror.

Tidal marshes trap microplastics, raising risks for ecosystems and people
Freshwater tidal marshes, critical for wildlife and coastal protection, are now serving as microplastic catch basins, according to a team of researchers at Penn State. They recently found that these marshes trap large amounts of diverse plastics, with concentrations and ecological risks increasing downstream.

Strong coupling of a microwave photon to an electron on helium
Electrons bound to the surface of superfluid helium have been proposed for scalable charge and spin-based quantum computing. However single electron quantum measurement in this system has remained elusive. Here we use a hybrid circuit quantum electrodynamic (cQED) device that comprises a quantum dot and a high-impedance superconducting resonator to demonstrate, for the first time, strong coupling between the resonator microwave field and the motional quantum state of the electron. We find a cou…

Generation of frequency-bin-encoded dual-rail cluster states via time-frequency multiplexing of microwave photonic qubits
Cluster states are a class of multi-qubit entangled states with broad applications such as quantum metrology and one-way quantum computing. Here, we present a protocol to generate frequency-bin-encoded dual-rail cluster states using a superconducting circuit consisting of a fixed-frequency transmon qubit, a resonator and a Purcell filter. We implement time-frequency multiplexing by sequentially emitting co-propagating microwave photons of distinct frequencies. The frequency-bin dual-rail encodi…
