About the cover

The cover shows an artist’s impression of the Jupiter-like gas giant KELT-9b (bottom) in orbit around the massive star KELT-9. In this issue, Scott Gaudi, Keivan Stassun and their colleagues report the discovery of KELT-9b and reveal it to be one of the hottest exoplanets so far identified. Its dayside surface temperature is about 4,600 K — hotter than most stars, and hot enough to vaporize its atmosphere and to dissociate any molecules into their constituent atoms. The planet is nearly three times more massive than Jupiter but only half as dense. It takes roughly 1.5 days to orbit its host star, and, because it is constantly being blasted with high levels of ultraviolet radiation, it may be shedding a tail of material much like a comet. The rate of ablation may be sufficient for KELT-9b to evaporate completely before its host star reaches the end of its life — assuming that the star doesn ’t grow and engulf the planet first. As only the seventh ‘hot Jupiter’ to be found orbiting a hot A-type star, KELT-9b should help deepen understanding of planetary systems around massive stars, the authors say.

    Investigations of an Icelandic volcanic eruption confirm that sulfate aerosols caused a discernible yet transient brightening effect, as predicted, but their effect on the liquid water path was unexpectedly negligible.

    Exosomes improve the delivery of siRNA to mutant KRAS in the pancreatic tumours and bypass immune clearance better than artificial liposomes, probably owing to enhanced macropinocytocis and presence of CD47 on exosomes, respectively.

    When the Universe was just 3 billion years old, half of the most massive galaxies had already ceased star formation, and such a galaxy has now been observed using gravitational lensing, unexpectedly turning out to be a compact, fast-spinning disk galaxy rather than a proto-bulge galaxy.

    PTEN, a known tumour suppressor, inhibits the FXBL2-dependent degradation of IP3R3, an IP3 receptor, thus augmenting IP3R3-mediated calcium release from the endoplasmic reticulum to mitochondria and inducing apoptosis; inhibiting FXBL2 sensitizes PTEN-deficient tumours to photodynamic therapy.
