Evolutionary divergence between homologous X-Y chromosome genes shapes sex-biased biology.

Sex chromosomes are a fundamental aspect of sex-biased biology, but the extent to which homologous X-Y gene pairs ('the gametologs') contribute to sex-biased phenotypes remains hotly debated. Although these genes tend to exhibit large sex differences in expression throughout the body (XX females can express both X members, and XY males can express one X and one Y member), there is conflicting evidence regarding the degree of functional divergence between the X and Y members. Here we develop and apply co-expression fingerprint analysis to characterize functional divergence between the X and Y members of 17 gametolog gene pairs across >40 human tissues.

A Microwave-Strengthened Supramolecular Adhesive: from Flexible Pressure Sensitive Bonding to Strong and Muti-Reusable Hot Melt Bonding.

A microwave-strengthened supramolecular adhesive by introducing maleic acid amide bonds into the cross-linked networks of catechol-based monomers and iron oxide nanoparticles is reported. Under microwave irradiation, the supramolecular adhesive can be rapidly heated up, causing the transformation from maleic acid amide bonds to maleimide bonds and thus the increase of its cohesive strength. The supramolecular adhesive can flexibly bond substrates like pressure sensitive adhesives during the bonding procedure and shows an adhesion strength of 0.

Achieving advanced hydrogen evolution under large current density using an amorphous/crystalline core-shell electrocatalyst of a-NiCoP/CoP.

Non-precious transition metal-based electrocatalysts with high activities are promising candidates for substituting Pt- or Ru-based electrocatalysts in hydrogen evolution. In this study, we propose core-shell engineering to combine the amorphous NiCoP and crystalline CoP (a-NiCoP/CoP@NF), which requires an ultra-low overpotential of only 26 mV to achieve the benchmark current density of 10 mA cm. Furthermore, it achieves an industrial-level hydrogen evolution current density of 500 mA cm with excellent stability.

Results showed that a negative correlation between bubble size and subharmonic resonance frequency is readily obtained from the radius response curves.

Activation strategies and effectiveness of Intelligent safety systems for reducing pedestrian injuries in autonomous vehicles.

Intelligent safety systems (ISS) for autonomous vehicles, integrating advanced perception capabilities and passive protection devices, are expected to reshape traditional pedestrian safety systems and play a key role in reducing the risk of pedestrian injuries in traffic accidents.

Age-related differences in psychopathology within sex chromosome trisomies.

Sex chromosome trisomies (SCTs) are a group of genetic disorders characterized by presence of a supernumerary sex chromosome, resulting in karyotypes other than XX or XY. These include XXX (Trisomy X), XXY (Klinefelter syndrome), and XYY (Jacobs syndrome). Sex chromosome trisomies have been linked to increased risk for psychopathology; however, this relationship warrants additional research.
