Among them, Dux has been considered as a master inducer for regulating ZGA process (3 – 5). Dux (also named as Duxf3) in mice and its human homolog DUX4 are double homeodomain genes activated during ...
Assessing the ergodicity of graphene liquid cell electron microscope measurements, we report that loop states of circular DNA interconvert reversibly and that loop numbers follow the Boltzmann ...
Correction for Yang et al., How surface charges affect interdroplet freezing ...

Open in Viewer (A) Schematic of a photocell consisting of quantum dots sandwiched between p and n doped semiconductors. Open circuit voltage and solar photon energy ℏνh are related by the Carnot ...
Meteorites provide important information about the formation of the Solar System and the distribution of solids and volatiles throughout it. However, meteorites that land on Earth display biases ...
Journal Club posts are short news stories featuring a recent important, timely journal article selected by one of our Journal Club panelists, who are post-doctoral associates and graduate students in ...
Dive into PNAS Front Matter for editorials, interviews, science news, and commentary that offer expert perspective on today’s most important research findings.
Extracellular redox-active compounds, flavins and other quinones, have been hypothesized to play a major role in the delivery of electrons from cellular metabolic systems to extracellular insoluble ...
Phonon softening and crystallographic orientation of strained graphene studied by Raman spectroscopy
We present a systematic study of the Raman spectra of optical phonons in graphene monolayers under tunable uniaxial tensile stress. Both the G and 2D bands exhibit significant red shifts. The G band ...
We present a simple nitrogen (N) isotope model to investigate the partitioning of gaseous (fgas) vs. leaching (fleaching) pathways of N removal from the nonagricultural (i.e., unmanaged) terrestrial ...
We describe a full structural model for amyloid fibrils formed by the 40-residue β-amyloid peptide associated with Alzheimer's disease (Aβ1–40), based on numerous constraints from solid state NMR a ...
