pH‐mediated activation of the lysosomal arginine sensor SLC38A9
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Drosha drives the formation of DNA:RNA hybrids around DNA break sites to facilitate DNA repair
The mechanism through which Drosha and Dicer affect DNA repair is not clear. Here the authors use a high-throughput approach to uncover the role of Drosha in promoting DNA:RNA hybrids at DNA damaged sites.

Repair of DNA Double-Strand Breaks in Heterochromatin
DNA double-strand breaks (DSBs) are among the most damaging lesions in DNA, since, if not identified and repaired, they can lead to insertions, deletions or chromosomal rearrangements.

Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

RPAP3 provides a flexible scaffold for coupling HSP90 to the human R2TP co-chaperone complex
The R2TP/PFDL co-chaperone facilitates assembly of RNA polymerase II and PI3-kinase-like kinases such as mTOR by a so far unknown mechanism. Here authors provide the cryo-EM structure of human R2TP, which shows how RPAP3 serves as a flexible platform to ...

The Involvement of Aβ42 and Tau in Nucleolar and Protein Synthesis Machinery Dysfunction
Alzheimer’s disease (AD) is the most common form of dementia and is distinguished from other dementias by observation of extracellular Amyloid-β (Aβ) plaques and intracellular neurofibrillary tangles, comprised of fibrils of Aβ and tau protein ...

The application of encapsulation material stability data to photovoltaic module life assessment [PDF]
For any piece of hardware that degrades when subject to environmental and application stresses, the route or sequence that describes the degradation process may be summarized in terms of six key words: LOADS, RESPONSE, CHANGE, DAMAGE, FAILURE, and ...
