BACKGROUND: Indigenous social determinants of health, including the ongoing impacts of
colonization, contribute to increased rates of chronic disease and a health equity gap for …

A complete mitochondrial (mt) genome sequence was reconstructed from a 38,000 year-old
Neandertal individual with 8341 mtDNA sequences identified among 4.8 Gb of DNA …

Neandertals, the closest evolutionary relatives of present-day humans, lived in large parts of
Europe and western Asia before disappearing 30,000 years ago. We present a draft …

It is proved that the physical states of the open-string sector of the ten-dimensional string
theory form supersymmetry multiplets. The proof is achieved by first constructing a new …

The coupled N = 1 Yang-Mills plus supergravity theory in ten dimensions can be made
anomaly-free for SO(32) or E 8 × E 8 . Only the case of SO(32) is known to correspond to a …

A characteristic feature of eukaryotic cells is that the primary transcription products of their
structural genes (pre-mRNAs) undergo a variety of post transcriptional modifications to create …

Neanderthals are the extinct hominid group most closely related to contemporary humans,
so their genome offers a unique opportunity to identify genetic changes specific to …

With the use of x-ray absorption spectroscopy, we have found that the Fe-O bond in
chloroperoxidase compound II (CPO-II) is much longer than expected for an oxoiron(IV) (ferryl) unit; …

Twenty-five years ago, Michael Green, John Schwarz, and Edward Witten wrote two volumes
on string theory. Published during a period of rapid progress in this subject, these volumes …

INTRODUCTION Crocodilians and birds are the two extant clades of archosaurs, a group
that includes the extinct dinosaurs and pterosaurs. Fossils suggest that living crocodilians (…
