Preferential attachment (PA) is a widely observed behavior in many living systems and has been used in modeling many networks. The aim of this work is to show that the mechanism of PA is a consequence of the fundamental principle of least effort. We derive PA directly from this principle in maximizing an efficiency function. This approach not only allows a better understanding of the different PA mechanisms already reported but also naturally extends these mechanisms with a non-power law probability of attachment. The possibility of using the efficiency function as a general measure of attachment efficiency is also investigated.

Phycobilisomes (PBS) are the major photosynthetic light-harvesting complexes in cyanobacteria and red algae. While the structures of PBS have been determined in atomic resolutions, how PBS are attached to the reaction centers of photosystems remains less clear. Here, we report that a linker protein (LcpA) is required for the attachment of PBS to photosystem II (PSII) in the cyanobacterium sp.

The abundance and sequence of satellite DNA at and around centromeres is evolving rapidly despite the highly conserved and essential process through which the centromere directs chromosome inheritance. The impact of such rapid evolution is unclear. Here we find that sequence-dependent DNA shape dictates packaging of pericentromeric satellites in female meiosis through a conserved DNA-shape-recognizing chromatin architectural protein, high mobility group AT-hook 1 (HMGA1).

Article Synopsis
- Control of individual atomic spins is essential for advancements in spintronics, quantum sensing, and quantum information processing, with scanning tunneling microscopy (STM) being a effective tool for manipulation.
- The research presents a new method for self-assembling magnetic organometallic complexes using iron atoms and specific molecules (Cu(dbm) and FePc) on a silver substrate, effectively forming complexes that mimic metallocenes.
- Magnetic properties of these complexes show a notable Kondo effect, which is explained through density functional theory calculations indicating that the interaction between Fe 3d-orbitals and benzene π-orbitals enhances Kondo screening, offering insights for designing hybrid organometallic systems.
Distinctive aspects of ligand binding to G4 DNA structure flanked by the double helix.

Except for telomeres, G4 DNA structures in the human genome can be formed only within the context of double-stranded DNA. DNA duplexes flanking the G4 structure may potentially affect the G4 architecture and the binding of G4-specific ligands. Here, we examine the interaction of TMPyP4, NMM, and PDS ligands with three structures formed by the same DNA fragment containing the (GGGT) sequence: the G4 in duplex (dsG4), G4 in single-stranded DNA (ssG4) and perfect duplex DNA (ds).

This paper presents a theoretical study on the distinguishable regiodivergent C-C Myers-Saito and C-C Schmittel routes of benzannelated enyne-allene cycloaromatizations, in which substitutions on the terminal alkyne by alkyl (-CH, -CHCH, -CH(CH) and -C(CH)) and aryl (-CH and -CH(CH)) groups were included. Mechanistic differences were found between substituents attached to alkynes with and without α-H, whereas in the former the Schmittel cyclization proceeds together with 1,8-H migration, in the latter it does so as the sole primitive event. It was also observed that bulky substituents preferentially favor the C-C Schmittel route, and the statistical prediction of regioselectivity is greatly affected when the ratio of accessible vibrational microstates of the transition states is included, especially in highly competing routes, , ΔΔ → 0.
