GHRHR Deficiency Enhances Retinal Ganglion Cell Survival and Visual Functions in Experimental Glaucoma by Inhibiting Ferroptosis

Advanced Science, EarlyView.
Glaucoma, a major cause of blindness, involves retinal ganglion cell (RGC) degeneration. This study shows growth hormone‐releasing hormone receptor (GHRHR) deficiency preserves RGC survival and restores vision, unlike activation which only aids survival.

Assessing Nitrogen Limitation in Inoculated Soybean in Southern Brazil

Agrosystems, Geosciences & Environment, 2019
Core Ideas Soybean yield did not respond to low starter fertilizer N rates in soils with high organic matter content. Nitrogen limitation tended to be greater in low compared with medium‐high yield levels.

Ecology and Biotechnology of Microbial Nitrogen Fixation

CHIMIA, 1987
Seventy-eight percent of the air we breathe in is molecular nitrogen (N2) – and the same amount we breathe out. Thus, human beings do not have the privilege of fixing N2. Rather, this is the domain of the diazotrophic bacteria.

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

ML Workflows for Screening Degradation‐Relevant Properties of Forever Chemicals

Advanced Science, EarlyView.
The environmental persistence of per‐ and polyfluoroalkyl substances (PFAS) necessitates efficient remediation strategies. This study presents physics‐informed machine learning workflows that accurately predict critical degradation properties, including bond dissociation energies and polarizability.

New hints on nutrients dynamics and their impact on carbon sequestration in the Mediterranean Sea

, 2009
In the World Ocean nitrogen and phosphorus cycles are deeply linked to the carbon cycle. As nitrate and phosphate play an important role in controlling biological production, the intensity of atmospheric carbon sequestration is strongly influenced by ...

SERS Facemask for Rapid and Portable Sensing Mycobacterium Tuberculosis Antigens for TB Screening

Advanced Science, EarlyView.
Our study introduced an Au─Ag embedded covalent organic framework (U@COF) ‐mediated facemask for sensing TB antigen ESAT‐6/CFP‐10 complex in clinical droplet samples toward TB screening. Practical analysis of clinical samples demonstrated the availability of our facemask, which is capable of identifying the TB subjects (N = 17) from healthy candidates (

Is moss-associated nitrogen fixation controlled by the same factors across shoots, species and sites?

Environmental and Experimental Botany
Biological N2 fixation performed by moss-associated cyanobacteria is among the main sources of new nitrogen (N) input in pristine subarctic ecosystems.
