Thalamic reticular impairment underlies attention deficit in Ptchd1Y/− mice p.58

PTCHD1 deletion in humans leads to attention deficits, intellectual disability, and autism spectrum disorders; mouse PTCHD1 is enriched in the thalamic reticular nucleus (TRN) and TRN-restricted Ptchd1 deletion in mice led to attention-deficit hyperactivity, which could be rescued by modulating calcium-dependent potassium channel activity, suggesting that a TRN deficit may underlie core impairments associated with neurodevelopmental disorders and it may be possible to identify therapeutic targets for individuals with attention disorders.

Recent near-Earth supernovae probed by global deposition of interstellar radioactive 60Fe p.69

The rate of supernovae in our local Galactic neighbourhood within a distance of about 100 parsecs from Earth is estimated to be one every 2–4 million years, based on the total rate in the Milky Way (2.0 ± 0.7 per century). Recent massive-star and supernova activity in Earth’s vicinity may be traced by radionuclides with half-lives of up to 100 million years, if trapped in interstellar dust grains that penetrate the Solar System. One such radionuclide is 60Fe (with a half-life of 2.6 million years), which is ejected in supernova explosions and winds from massive stars. Here we report that the 60Fe signal observed previously in deep-sea crusts is global, extended in time and of interstellar origin from multiple events. We analysed deep-sea archives from all major oceans for 60Fe deposition via the accretion of interstellar dust particles. Our results reveal 60Fe interstellar influxes onto Earth at 1.5–3.2 million years ago and at 6.5–8.7 million years ago. The signal measured implies that a few per cent of fresh 60Fe was captured in dust and deposited on Earth. Our findings indicate multiple supernova and massive-star events during the last ten million years at distances of up to 100 parsecs.

The locations of recent supernovae near the Sun from modelling 60Fe transport p.73

The signature of 60Fe in deep-sea crusts indicates that one or more supernovae exploded in the solar neighbourhood about 2.2 million years ago. Recent isotopic analysis is consistent with a core-collapse or electron-capture supernova that occurred 60 to 130 parsecs from the Sun. Moreover, peculiarities in the cosmic ray spectrum point to a nearby supernova about two million years ago. The Local Bubble of hot, diffuse plasma, in which the Solar System is embedded, originated from 14 to 20 supernovae within a moving group, whose surviving members are now in the Scorpius–Centaurus stellar association. Here we report calculations of the most probable trajectories and masses of the supernova progenitors, and hence their explosion times and sites. The 60Fe signal arises from two supernovae at distances between 90 and 100 parsecs. The closest occurred 2.3 million years ago at present-day galactic coordinates l = 327°, b = 11°, and the second-closest exploded about 1.5 million years ago at l = 343°, b = 25°, with masses of 9.2 and 8.8 times the solar mass, respectively. The remaining supernovae, which formed the Local Bubble, contribute to a smaller extent because they happened at larger distances and longer ago (60Fe has a half-life of 2.6 million years). There are uncertainties relating to the nucleosynthesis yields and the loss of 60Fe during transport, but they do not influence the relative distribution of 60Fe in the crust layers, and therefore our model reproduces the measured relative abundances very well.

Coherent feedback control of a single qubit in diamond p.77

Continuous directional water transport on the peristome surface of Nepenthes alata p.85

Insects are captured by the carnivorous plant Nepenthes alata when they ‘aquaplane’ on the wet rim, or ‘peristome’, of the plant’s pitcher organ; here it is shown that unidirectional water flow is crucial to the complete wetting of the peristome, and that the underlying mechanism involves multiscale structural features.

Northern Hemisphere hydroclimate variability over the past twelve centuries p.94

A very large set of proxy data is used to reconstruct Northern Hemisphere hydroclimate variability over the past twelve centuries, to benchmark climate model simulations of hydroclimate; the twentieth-century intensification of hydroclimate extremes seen in the model simulations is not supported by the proxy reconstruction.

Structural basis of lenalidomide-induced CK1α degradation by the CRL4CRBN ubiquitin ligase p.127

Thalidomide and its derivatives, lenalidomide and pomalidomide, are immune modulatory drugs (IMiDs) used in the treatment of haematologic malignancies. IMiDs bind CRBN, the substrate receptor of the CUL4–RBX1–DDB1–CRBN (also known as CRL4CRBN) E3 ubiquitin ligase, and inhibit ubiquitination of endogenous CRL4CRBN substrates. Unexpectedly, IMiDs also repurpose the ligase to target new proteins for degradation. Lenalidomide induces degradation of the lymphoid transcription factors Ikaros and Aiolos (also known as IKZF1 and IKZF3), and casein kinase 1α (CK1α), which contributes to its clinical efficacy in the treatment of multiple myeloma and 5q-deletion associated myelodysplastic syndrome (del(5q) MDS), respectively. How lenalidomide alters the specificity of the ligase to degrade these proteins remains elusive. Here we present the 2.45 Å crystal structure of DDB1–CRBN bound to lenalidomide and CK1α. CRBN and lenalidomide jointly provide the binding interface for a CK1α β-hairpin-loop located in the kinase N-lobe. We show that CK1α binding to CRL4CRBN is strictly dependent on the presence of an IMiD. Binding of IKZF1 to CRBN similarly requires the compound and both, IKZF1 and CK1α, use a related binding mode. Our study provides a mechanistic explanation for the selective efficacy of lenalidomide in del(5q) MDS therapy. We anticipate that high-affinity protein–protein interactions induced by small molecules will provide opportunities for drug development, particularly for targeted protein degradation.
