Edge sites dominate the hydrogen evolution reaction on platinum nanocatalysts - Nature Catalysis
Nature· 23 hours agoPt is the most active catalyst for the hydrogen evolution reaction in acidic media, but the precise nature of its active sites remains elusive. Now electrical transport spectroscopy and molecular ...
ADA2 regulates inflammation and hematopoietic stem cell emergence via the A2bR pathway in zebrafish...
Nature· 23 hours agoA DADA2 zebrafish model with cecr1b deficiency was generated. Characterization of hematopoietic processes revealed a role of Cecr1b in regulating inflammation and hematopoietic stem cell production through the A2br-mediated adenosine signaling.
Fact Check: Posts Claim Men's Testicles Have Taste Receptors. It's Not as Nutty as It Seems
Snopes via Yahoo News· 4 hours ago'Expression of Taste Receptor 2 Subtypes in Human Testis and Sperm'. Journal of Clinical Medicine,...
A DNA demethylase reduces seed size by decreasing the DNA methylation of AT-rich transposable...
Nature· 2 days agoA study on a soybean DNA demethylase reveals that seed size is negatively regulated by GmDMEa, which is closely linked to methylation on transposon elements.
Brain endothelial cells promote breast cancer cell extravasation to the brain via EGFR-DOCK4-RAC1...
Nature· 5 days agoBrain endothelial cells activate EGFR signaling in triple-negative breast cancer cells, promoting brain metastasis. DOCK4 is crucial for cancer cell extravasation to the brain, with EGFR activation driving cell elongation reversed by Afatinib.
Mercury contamination is an invisible threat to declining migratory shorebirds along the East...
Nature· 7 days agoOver one-third of the sampled shorebirds along the East Asian-Australasian Flyway are facing Hg risk. Tringa genus in South China was at the highest risk. Feather Hg was best explained by feathers ...
Multidrug-resistant phenotypes of genetically diverse Escherichia coli isolates from healthy...
Nature· 6 days agoΒ-lactamases-producing Escherichia coli are a widely distributed source of antimicrobial resistance (AMR), for animals and humans. Little is known about the sensitivity profile and genetic characteristics ...
TBC9, an essential TBC-domain protein, regulates early vesicular transport and IMC formation in...
Nature· 5 days agoA study suggests that TBC9, one of the Rab GTPase Activating Proteins, is crucial for early vesicular transport and inner membrane complex formation by regulating Rab2, Rab11A and Rab11B in Toxoplasma gondii.
Sustained attention operates via dissociable neural mechanisms across different eccentric locations...
Nature· 7 days agoIn primates, foveal and peripheral vision have distinct neural architectures and functions. However, it has been debated if selective attention operates via the same or different neural mechanisms ...
p52-ZER6/IGF1R axis maintains cancer stem cell population to promote cancer progression by enhancing...
Nature· 2 days agoCancer stem cells (CSCs), which are distinct subpopulations of tumor cells, have a substantially higher tumor-initiating capacity and are closely related to poor clinical outcomes. Damage to ...
