Self-modulated hydrogen electrocatalysis on sub-2-nm platinum nanoparticles by in situ generated surface hydrides

open access: yesNature Communications
Revealing the surface structure evolution under working conditions is crucial for understanding the activity and stability of electrocatalysts. Platinum, the state-of-the-art electrocatalyst for hydrogen oxidation in fuel cells or hydrogen evolution in ...

Molecular bases of circadian magnesium rhythms across eukaryotes

open access: yesFEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Enhanced enzyme stability at the interphase of water-oil for continuous-flow olefin epoxidation

open access: yesNature Communications
The practical applications of enzymes often require their immobilization for multiple recycling or long-term running. However, practically efficient enzyme immobilization methods are lacking.

Do value-added estimates add value ? accounting for learning dynamics [PDF]

open access: yes
Evaluations of educational programs commonly assume that what children learn persists over time. The authors compare learning in Pakistani public and private schools using dynamic panel methods that account for three key empirical challenges to widely ...

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Economic Value Added [PDF]

open access: yes, 2008
Economic Value Added (EVA), when applied properly in a company, impacts all departments and decisions. The equation for EVA as well as the adjustments that must be made to current accounting practices is the basis for an understanding of EVA. The success

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Non-destructive real-time monitoring of underground root development with distributed fiber optic sensing

open access: yesPlant Methods
Crop genetic engineering for better root systems can offer practical solutions for food security and carbon sequestration; however, soil layers prevent the direct visualization of plant roots, thus posing a challenge to effective phenotyping.
