Nature or nurture: What determines investor behavior?

open access: yes
Using data on identical and fraternal twins' complete financial portfolios, we decompose the cross-sectional variation in investor behavior. We find that a genetic factor explains about one-third of the variance in stock market participation and asset ...

Investor protection and business creation [PDF]

open access: yes
We study the effects of investor protection on the availability of external finance, entrepreneurship, and creation of new firms in an equilibrium search model of private capital markets.

Hypothalamic POMC Neurons Gate the Fear‐Feeding Trade‐Off

open access: yesAdvanced Science, EarlyView.
Hungry animals must continually arbitrate between feeding and defensive behaviors when confronted with potential threats. We show that hypothalamic POMC neurons engage CRH‐expressing stress circuits and downstream hormonal responses to coordinate this behavioral selection between competing behaviors.

Pyrolyzed Photoresist as a Continuous‐Tone Mask for Grayscale Lithography

open access: yesAdvanced Science, EarlyView.
True grayscale contact photolithography masks are created by pyrolysis of 3D multiphoton resist patterns. The resulting carbon masks retain micrometer‐scale patterned features while providing continuous‐tone optical transmission. This approach provides access to high‐quality grayscale lithography without requiring exotic materials or commercial mask ...

An AI‐Driven Framework for Directed Self‐Assembly Toward Design‐Technology Co‐Optimization

open access: yesAdvanced Science, EarlyView.
An artificial intelligence (AI)‐driven closed‐loop framework integrates experiment, three‐dimensional physics‐based simulation, and template design for directed self‐assembly (DSA). Guided by experimental data, AI‐assisted calibration accelerates model optimization, supports morphology prediction, and identifies template windows.

Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

open access: yesAdvanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

Rethinking Cochlear Implants: The Need for Precise Temporal Coding

open access: yesAdvanced Science, EarlyView.
Spatial hearing relies on sensitivity to interaural temporal cues, but this sensitivity is often poorly developed in patients with cochlear implants, particularly those with early‐onset hearing loss. Rats with cochlear implants, however, demonstrate excellent temporal sensitivity, suggesting that this limitation is not inevitable.
