Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Quantum Physics and the Existence of God
Interpretations of quantum physics are shown to presuppose the reality of consciousness. But if a minimal realism about the external world is true, then the consciousness presupposed by quantum reality cannot be only that of the scientific observer ...

PHYSICAL REALIZABILITY BOUNDARIES OF OBSERVATION
This paper examines the physical limits on observation by treating measurement as a force-mediated, energy-consuming interaction performed by finite matter–energy systems. By analyzing observation through physical admissibility, enforcement, removal, and invariance, it shows that increasing precision or duration necessarily increases energy ...

RNA‐related functions of BRCA2 in transcription, replication, and genome stability
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Advanced Physics: Reference Frames
The above simulations present a classic physics thought experiment, sometimes called a Gedanken experiment (from the German). An object is moving to the right in a straight line with constant speed. The spaceship is accelerating upward.

Development of quantum perspectives in modern physics [PDF]
Introductory undergraduate courses in classical physics stress a perspective that can be characterized as realist; from this perspective, all physical properties of a classical system can be simultaneously specified and thus determined at all future ...

Artificial molecular machines and motors—Design and control of nanoscale motion
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Observation A Physical Definition Independent of Observers
This paper defines observation strictly as a physical process, independent of observers, perception, or interpretation. Using only established physical principles, observation is reduced to a dissipative interaction that produces a persistent, irreversible record.

Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
