  • Current polygenic risk scores for prostate cancer do not leverage biological mechanisms and remain inadequate for patients with African ancestry. Here, the authors employ a deep learning model to identify 2,407 non-coding polymorphisms with greater frequency in African American individuals that may affect enhancer activity in prostate cancer-related pathways, leading to more accurate polygenic risk scores.

  • Polar skyrmions are nanoscale topological structures of electric polarizations. Their collective modes, dubbed as “skyrons”, are discovered by the terahertz-field-excitation, femtosecond x-ray diffraction measurements and advanced modeling.

  • Understanding transformations of non-equilibrium materials is a key open scientific question. Here the pathway by which different polar supertextures undergo dynamical correlations and collectively transform into a metastable supercrystal state is revealed experimentally and theoretically over seven orders of magnitude timescale.

  • Electronic bandwidth modulation by static pressure has been explored in several material families. Wang et al. use temperature-dependent Raman spectroscopy and density functional theory to reveal phonon-driven modulation of electronic pseudogap and density wave fluctuations in a ruthenate Ca3Ru2O7.

  • The authors report on harnessing sp2-organic molecules as a basis for uniformly initiating the homoepitaxial-like, size-controlled, synthesis of sub-5 nm semiconducting graphene nanoribbons for electronics via chemical vapor deposition.

  • A synthetic strategy is developed towards highly amphiphilic cellulose nanocrystals (CNCs) by selectively introducing carboxylic acid groups at the reducing end and –C8 units on the surface. The resulting chloroform soluble CNCs formed an exceptionally stable monolayer at the air/water interface, and resulted in a well-defined LB isotherm, allowing their facile transfer to both hydrophilic and hydrophobic substrates. These monolayers were successfully transferred onto substrates to create monolayer or smooth multilayer films.
