Radially extended disk winds could be the key to unlocking how protoplanetary disks accrete and how planets form and migrate. A distinctive characteristic is their nested morphology of velocity and chemistry. Here we report JWST/NIRSpec spectro-imaging of four young stars with edge-on disks in the Taurus star-forming region that demonstrate the ubiquity of this structure. In each source, a fast collimated jet traced by [Fe II] is nested inside a hollow cavity within wider lower-velocity H2 and, in one case, also CO ro-vibrational (v=1-0) emission. Furthermore, in one of our sources, ALMA CO(2-1) emission, paired with our NIRSpec images, reveals the nested wind structure extends further outward. This nested wind morphology strongly supports theoretical predictions for wind-driven accretion and underscores the need for theoretical work to assess the role of winds in the formation and evolution of planetary systems

Accretion Burst Crystallizes Silicates in a Planet-Forming Disk
During an accretion burst of the embedded protostar EC 53, JWST mid-infrared spectra reveal newly appearing crystalline silicate emission, indicating in-situ thermal annealing of dust in the hot inner disk.

JWST/MIRI Reveals the Evolution from Molecular to Atomic Disk Winds
Across 72 protoplanetary disks, JWST shows atomic jets and molecular winds dominate at high accretion rates and give way to predominantly atomic winds as accretion declines.

JWST Imaging of Edge-on Protoplanetary Disks. IV. Mid-infrared Dust Scattering in the HH 30 disk
Multi-wavelength imaging of HH 30 shows micron-sized grains are vertically mixed in the disk surface, millimeter grains are only moderately settled, and the apparent disk inclination changes with wavelength.

JWST Edge-on Disk Ice (JEDIce): Vibrationally hot, rotationally cold H$_2$ in the outer disk of Oph 163131 non-thermally excited by UV and cosmic rays
Outer-disk H2 in Oph 163131 is v-hot and J-cold from combined UV and cosmic-ray excitation plus collisions, implying an effective CR ionization rate of order 10^{-15} s^{-1}.

JWST/MIRI Detection of Molecular H$_2$ Winds from an Edge-on Class II Source HV Tau C
The edge-on Class II disk HV Tau C hosts a spatially extended, wide-angled molecular hydrogen wind with warm (~600 K) and hot (~2000 K) components and a mass-loss rate near 1e-8 solar masses per year.

Dust and Gas Transport in Substructured Nonideal MHD Wind-Launching Disks with Embedded Planets
In magnetized wind-launching disks, planet-opened gaps remain partially permeable: small grains and gas leak through, while large grains are filtered, making substructures regulators rather than barriers.

A correlation between accretion and outflow rates for Class II Young Stellar Objects with full and transition disks
Centimeter free-free emission in Class II disks correlates with accretion rate, and the authors infer it traces MHD winds or jets in both full and transition disks.

Ionized gas emission in protoplanetary disks with the SKAO
Synthetic SKA-Mid observations of simulated MHD and photoevaporative disk winds show that free-free emission is detectable in hours and stacked hydrogen recombination lines are spectrally resolvable in ~10 hours.
