Addressing Systematics in the Traceback Age of the β Pictoris Moving Group

The Astrophysical Journal, 2023
We characterize the impact of several sources of systematic errors on the computation of the traceback age of the β Pictoris moving group ( β PMG). We find that uncorrected gravitational redshift and convective blueshift bias absolute radial velocity ...

Autonomous Folding of Soft Matter From Living Polymers

Advanced Materials, EarlyView.
Origami structures are endowed with “living” polymer creases that grow, remodel, and stiffen in response to nutrient solutions. This post‐fabrication growth enables autonomous folding, iterative regrowth, and mechanical tuning involving origami assemblies, such as cranes, Miura‐ori tessellations, rigid and non‐rigid square‐twist patterns, establishing ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Stellar population and kinematics of NGC404 [PDF]

, 2010
Context. NGC404 is a nearly face-on nearby low-luminosity lenticular galaxy. Probing its characteristics provides a wealth of infor-mation on the details of possible evolution processes of dS0 galaxies which may not be possible in other, more distant ...

Discovery of the Magellanic Stellar Stream Out to 100 kpc

The Astrophysical Journal, 2023
The Magellanic Stream (MS)—an enormous ribbon of gas spanning 140° of the southern sky trailing the Magellanic Clouds—has been exquisitely mapped in the five decades since its discovery.

Transient Cytoskeletal Anisotropy Encodes Short‐Term Mechanical Memory in Glioblastoma Cells

Advanced Materials, EarlyView.
The same mechanical deformation can produce distinct cytoskeletal states depending on loading history. Experiments and constitutive modeling reveal that transient actin–vimentin anisotropy stores mechanical information and governs short‐term mechanical memory in glioblastoma cells.
