The structure of human CST reveals a decameric assembly bound to telomeric DNA
The CTC1-STN1-TEN1 (CST) complex is essential for telomere maintenance and resolution of stalled replication forks genome-wide. Here, we report the 3.0-angstrom cryo–electron microscopy structure of human CST bound to telomeric single-stranded DNA (ssDNA), which assembles as a decameric supercomplex. The atomic model of the 134-kilodalton CTC1 subunit, built almost entirely de novo, reveals the o

Photoelectron spectra of alkali metal-ammonia microjets: From blue electrolyte to bronze metal
Experimental studies of the electronic structure of excess electrons in liquids—archetypal quantum solutes—have been largely restricted to very dilute electron concentrations.

We report a robust cyclometalated iridium(III) complex bearing a chiral cyclopentadienyl

Spectral measurements of boundary-localized topological modes are commonly used to identify topological insulators.

Strecker et al . (Research Articles, 5 July 2019, p. 48) described a system for exploiting a Tn7-type transposon-encoded CRISPR-Cas system to make RNA-guided, programmable insertions. Although this system has great promise, we note that the well-established biochemistry of Tn7 suggests that the particular system used may insert not only the transposon but also the entire donor plasmid.

This latter outcome can be avoided by use of a 5' nicked DNA donor.
