Abstract. Aerosols play a major role in climate by influencing both radiative forcing and cloud condensation nuclei (CCN) formation, with organic aerosols

Strains of the arbuscular mycorrhizal (AM) fungus Rhizophagus irregularis belong to one of two nuclear organizations: homokaryons, which carry genetically similar nuclei, and dikaryons, which harbour two genetically distinct nuclear populations. Although traits tend to be conserved within each group, it is unclear whether their capacity to adapt or exhibit phenotypic plasticity in response to environmental change differs. Here, we tested whether dikaryotic strains have greater potential than homokaryotic strains for rapid adaptation or plasticity in response to shifts in soil phosphorus (P) availability. The experiment first included a conditioning phase in which we measured the growth responses of Allium ampeloprasum L. inoculated with four homokaryotic or four dikaryotic strains under contrasting soil P levels. Next, in the adaptive potential phase, we grew the conditioned strains under both low and high P to assess whether prior P exposure influenced subsequent mutualistic functioning. During conditioning, host biomass was greater under high than low P for both nuclear groups, but increased roughly 3.2-fold for dikaryons and 1.9-fold for homokaryons. In the adaptive potential phase, strains conditioned under low P enhanced host biomass significantly more than those conditioned under high P, and by a similar amount in both P environments. This effect did not differ between dikaryons and homokaryons, but its magnitude varied markedly among individual strains, from no benefit to a roughly two-fold increase in host biomass. Together, these results provide the first experimental evidence that conditioning AM fungi under low soil P can enhance their subsequent benefits to host plants, even when P availability increases. Soil P conditioning strategies for AM fungi, therefore, merit consideration in agriculture and other managed ecosystems, although the strong strain dependence of the effect implies that strain choice and conditioning regime would need to be optimized together.

When the universe was born, space was too hot and dense for atoms to exist. Even the constituents of atoms—the protons and neutrons that make up atomic nuclei—couldn’t immediately coalesce. Instead the newborn cosmos was filled with even smaller and more fundamental building blocks, quarks and gluons, which formed a smoothly flowing soup called quark-gluon plasma. Soon, though, the universe expanded, cooling down the soup. Gluons glued quarks together to make protons and neutrons, which floated around as a gas rather than a plasma. The change marked a phase transition, just as water can switch from vapor to liquid to solid ice. But key details of this profound primordial transition, such as its threshold energy and density, have remained deeply mysterious. That began to change around the turn of the millennium, when physicists started smashing gold ions together at nearly the speed of light inside the giant particle accelerator at Brookhaven National Laboratory on Long Island in New York State. Those smashups were so powerful that they briefly re-created the quark-gluon plasma from the big bang. Now researchers analyzing data from those collisions have seen an unexpected signal that offers new clues about how the cosmic transition happened eons ago...
