enabling not only the observation but also the manipulation of vibrational
wave-packet interference at ambient conditions. The technique could help to
unravel details of molecular function and dynamics in systems as diverse as
light-harvesting complexes, photoactive proteins and conjugated polymers.

Massive volcanic SO2 oxidation and sulphate aerosol deposition in Cenozoic
North America pp909-912
Volcanic eruptions release a large amount of sulphur dioxide. This is
oxidized to sulphate and can then form sulphate aerosol, which can affect
the Earth's radiation balance. Here, past volcanic eruptions and atmospheric
conditions are investigated by using sulphur and triple oxygen isotope
measurements of atmospheric sulphate preserved in the rock record. The
results show that seven eruption-related sulphate aerosol deposition events
occurred in the mid-Cenozoic era in the northern High Plains of North
America.

The importance of rift history for volcanic margin formation pp913-917
Rifting and magmatism are fundamental geological processes that shape our
planet's surface, but the nature of the relationship between these processes
has been controversial. Here a numerical model that explicitly accounts for
the effects of earlier episodes of extension has been applied to compare
magmatism generated at different locations during continental rifting. The
findings show that the volume of rift-related magmatism generated depends
not only on the mantle temperature but also on the rift history.

Ecological interactions are evolutionarily conserved across the entire tree
of life pp918-921
It is expected that closely related organisms are more likely to show
similar ecological interactions than less related ones. But this has been
tested only for certain types of interaction, and in a restricted set of
taxa. Now interaction networks have been constructed for 116 different
clades of related organisms, across the entire tree of life, and including
