<p class="xmsonormal"><span style="font-family:"Aptos Display",sans-serif;color:black">Empirical evidence famously indicates that we live in a universe with four extended spacetime dimensions and no "fifth forces" at low energies. Building realistic universes
from string theory runs into several challenges, among which achieving both of these conditions simultaneously. This is known as the scale separation problem. I will present a novel approach to this end, concocting four-dimensional string vacua directly from
the worldsheet formulation by analogy with the Banks-Zaks phenomenon in gauge theory. The resulting vacua are non-supersymmetric anti-de Sitter spacetimes with no intermediate effective description in higher dimensions. I will provide a working example in
four dimensions as a proof of principle.<o:p></o:p></span></p>

<p class="MsoNormal" style="background:white"><span style="color:black">The Solar wind Magnetosphere Ionosphere Link Explorer (SMILE) is a joint European Space Agency, Chinese Academy of Sciences mission due for launch in 2024 to explore coupling between the
solar wind and Earth’s magnetosphere. SMILE will simultaneously monitor the movement of the magnetopause boundary and the subsequent response of the Northern Hemisphere ionosphere using two imaging cameras with offset field of views. The magnetopause is known
to respond to changes in the incoming solar wind and interplanetary field, but this will be the first time that real-time images of this movement will be tracked. The high-latitude ionosphere is connected to near-Earth space via terrestrial magnetic field
lines. Phenomena in the ionosphere, such as patches of aurora and precipitating particle signatures may be provoked as a direct result of processes at the dayside magnetopause. Alternatively, nightside or magnetotail processes lead to the large-scale phenomena
such as a substorm. In this talk we will explore how SMILE will contribute to resolving the large outstanding questions regarding the Earth’s magnetosphere. We will examine the efforts of the global solar-terrestrial community to use multiple and varied experimental
data, for example from radar, ground magnetometers, and all-sky auroral imagers in unravelling these questions at large, medium, and small temporal and spatial scales.<o:p></o:p></span></p>
