Thyroid hormone signaling is essential for the maturation and survival of cochlear root cells in mice.

Thyroid hormone and its receptors (TRs) are crucial for late-stage cochlear development and the maintenance of endocochlear potential (EP), yet the mechanisms underlying EP reduction in their absence remain unclear. Cochlear outer sulcus root cells undergo significant morphological changes during late-stage development and are thought to play a role in maintaining endolymph homeostasis and EP. Nevertheless, it remains unknown whether thyroid hormone and TRs are essential for root cell differentiation and function.

Methane emissions from the Nord Stream subsea pipeline leaks.

The amount of methane released to the atmosphere from the Nord Stream subsea pipeline leaks remains uncertain, as reflected in a wide range of estimates. A lack of information regarding the temporal variation in atmospheric emissions has made it challenging to reconcile pipeline volumetric (bottom-up) estimates with measurement-based (top-down) estimates. Here we simulate pipeline rupture emission rates and integrate these with methane dissolution and sea-surface outgassing estimates to model the evolution of atmospheric emissions from the leaks.

Multifunctional Conjugated Polyphenol "Bridge" Capped the Upper Interface of Highly Efficient and Stable Inorganic Perovskite Solar Cells Fabricated in Air.

Carbon-based all-inorganic perovskite solar cells (C-PSCs) are promising alternatives compared with conventional organic-inorganic halide PSCs because of their good thermal stability. However, low carrier transport efficiency and energy level mismatch of the upper interface of the device limit the further improvement of power conversion efficiency (PCE), and all-inorganic perovskites are extremely sensitive to oxygen and humidity, which seriously damages the long-term stability of the device. Upper interface modification is an effective solution to improve the PCE and the stability of devices.
