They combine HS-AFM with molecular dynamics 🖥️ and nanomechanical measurements to show that IP6 rewires interactions between capsid proteins, favors the open state, and makes the lattice more resistant 💪🏻 to mechanical fatigue 3/3

They identify a structured region that binds and activates DDX11, an enzyme involved in DNA replication 🧬. Preserving the RNA fold despite changing its sequence retains this function, whereas disrupting the fold impairs chromosome cohesion 3/3

They combine experiments 🔬 and theory 📖 to reveal how the friction contrast produced by atomic defects depends on their depth. The results establish friction as a sensitive probe of individual defects in 2D materials. 3/3

In this work, the authors report substrate-induced 1D borophene-silver hybridization: atomic-scale coupling between borophene and Ag that turns the interface itself into an ordered 1D hybrid structure. 2/3 pubs.acs.org/doi/full/10.102…

The broader message is that for synthetic 2D materials such as borophene, the metal substrate is part of the chemistry, not an inert stage. Controlling this interaction could offer a route to anisotropic, atomically precise 1D electronic structures. 3/3

Starting from atomic C, atomic Si and H₂, they reconstruct the chemical pathway from atoms → molecules → nanodust, helping clarify how stellar environments produce the grains that later seed planets 🪐and interstellar matter ✨🌠 3/4

One particularly interesting aspect is the nanoscale perspective of the work 🔬. The study follows the formation of silicon carbide nanodust from atomic and molecular precursors ⚛️, highlighting the importance of characterizing matter at the nanometre scale 4/4

CO-functionalized tips are famous for ultrahigh resolution imaging, but what about their role in spectroscopy? The authors show how tip flexibility affects inelastic electron tunneling spectroscopy (IETS) by probing a single melamine isomer on Cu(001) 2/3 pubs.acs.org/doi/full/10.102…

They show that tip-molecule interactions tilt the CO, break symmetry, and lift vibrational degeneracy, causing a measurable blueshift. The effect depends on local chemistry, opening IETS as a sharp tool for surface physics & molecular identification 🔬 3/3

The authors show an unusual electronic state in monolayer NbSe₂. It’s not topological, but not a standard atomic band either. The electrons are centered at an empty spot in the lattice, not on any atom: an obstructed atomic band nature.com/articles/s41567-0… 2/3

We usually think electrons “live” on atoms ⚛️. The authors use #STM combined with theory to show that the electronic state is shifted off-site, even in an otherwise conventional band. It challenges a very basic picture of electrons in solids 3/3
