The global spectrum of plant form and function p.167

The authors found that the key elements of plant form and function, analysed at global scale, are largely concentrated into a two-dimensional plane indexed by the size of whole plants and organs on the one hand, and the construction costs for photosynthetic leaf area, on the other.

Eight per cent leakage of Lyman continuum photons from a compact, star-forming dwarf galaxy p.178

Far-ultraviolet observations of the nearby low-mass star-forming galaxy J0925+1403 show that the galaxy is leaking ionizing radiation with an escape fraction of about 8 per cent, which is sufficient to ionize intergalactic medium material that is about 40 times as massive as the stellar mass of the galaxy.

Weakened magnetic braking as the origin of anomalously rapid rotation in old field stars p.181

The age of a young to middle-aged star can be determined from how quickly or slowly it rotates, but the relationship breaks down for old stars; models now show that old stars are rotating much more quickly than expected, perhaps because magnetic winds are weaker and therefore brake the rotation less effectively.

Controlling many-body states by the electric-field effect in a two-dimensional material p.185

To be able to control the properties of a system that has strong electron–electron interactions using only an external electric field would be ideal, but the material must be thin enough to avoid shielding of the electric field in the bulk material; here pure electric-field control of the charge-density wave and superconductivity transition temperatures is achieved by electrolyte gating through an electric-field double layer transistor in the two-dimensional material 1T-TiSe2.

Rapid removal of organic micropollutants from water by a porous β-cyclodextrin polymer p.190

The global occurrence in water resources of organic micropollutants, such as pesticides and pharmaceuticals, has raised concerns about potential negative effects on aquatic ecosystems and human health. Activated carbons are the most widespread adsorbent materials used to remove organic pollutants from water but they have several deficiencies, including slow pollutant uptake (of the order of hours) and poor removal of many relatively hydrophilic micropollutants. Furthermore, regenerating spent activated carbon is energy intensive (requiring heating to 500–900 degrees Celsius) and does not fully restore performance. Insoluble polymers of β-cyclodextrin, an inexpensive, sustainably produced macrocycle of glucose, are likewise of interest for removing micropollutants from water by means of adsorption. β-cyclodextrin is known to encapsulate pollutants to form well-defined host–guest complexes, but until now cross-linked β-cyclodextrin polymers have had low surface areas and poor removal performance compared to conventional activated carbons. Here we crosslink β-cyclodextrin with rigid aromatic groups, providing a high-surface-area, mesoporous polymer of β-cyclodextrin. It rapidly sequesters a variety of organic micropollutants with adsorption rate constants 15 to 200 times greater than those of activated carbons and non-porous β-cyclodextrin adsorbent materials. In addition, the polymer can be regenerated several times using a mild washing procedure with no loss in performance. Finally, the polymer outperformed a leading activated carbon for the rapid removal of a complex mixture of organic micropollutants at environmentally relevant concentrations. These findings demonstrate the promise of porous cyclodextrin-based polymers for rapid, flow-through water treatment.

Iron-catalysed tritiation of pharmaceuticals p.195

An iron-catalysed method for the direct 3H labelling of pharmaceuticals by hydrogen isotope exchange using tritium gas is reported; the site selectivity of the iron catalyst is orthogonal to currently used iridium catalysts and allows isotopic labelling of complementary positions in drug molecules.

Critical insolation–CO2 relation for diagnosing past and future glacial inception p.200

A critical functional relationship between boreal summer insolation and global carbon dioxide concentration is proposed and tested with simulations; it accounts for the beginning of the past eight glacial cycles and predicts that the next one is unusually far off, even without the effect of anthropogenic emissions.

Earliest hominin occupation of Sulawesi, Indonesia p.208

New excavations in Sulawesi, where in situ stone artefacts associated with fossil remains of megafauna have been recovered from stratified deposits between 200,000 and 100,000 years ago, suggest that Sulawesi was host to a long-established population of archaic hominins.

Diet-induced extinctions in the gut microbiota compound over generations p.212

In mice on a low microbiota-accessible carbohydrate (MAC) diet, the diversity of the gut microbiota is depleted, and the effect is transferred and compounded over generations; this phenotype is only reversed after supplementation of the missing taxa via faecal microbiota transplantation, suggesting dietary intervention alone may by insufficient at managing diseases characterized by a dysbiotic microbiota.
