Breakthrough photothermal ammonia decomposition via low-barrier Ni-CeO2-x interfaces on carbon nanotubes
Abstract Efficient ammonia decomposition is crucial for hydrogen economy, but inexpensive Ni catalysts require excessively high temperatures due to limited N-N coupling. Here, we overcome this challenge by constructing a photothermal catalyst with closely interfaced, defect-rich CeO 2-x nanodomains and electron-rich Ni nanoparticles on carbon nanotubes. The Ni-CeO 2-x /CNTs catalyst achieves a hydrogen production rate of 298.4 mmol g cat -1 min -1 under full-spectrum light irradiation, which exceeds that of most reported Ru catalysts, and maintained stable activity for over 50 h in continuous-flow operation. The high performance arises from the synergistic effect of thermally promoted photocatalytic N-H bond cleavage and a largely reduced N-N coupling barrier, enabled by efficient photothermal conversion of carbon nanotubes and the up-shifted d-band center of the Ce-Ov-Ni interface (Ov = oxygen vacancy).

Facial femininity of potential rivals predicts jealousy in both heterosexual and lesbian women
Abstract Individuals displaying cues of higher mate value (e.g., attractive characteristics) are thought to represent a greater threat to pair bonds and, consequently, elicit greater jealousy. Previous studies reporting that more feminine potential rivals elicit greater jealousy in women used stimuli in which feminine characteristics were experimentally manipulated and assessed jealousy using forced-choice methods. However, this method for assessing perceptions has recently been criticised for lacking ecological validity. Consequently, in the current study, women rated how jealous they would feel if rivals depicted in natural (i.e., unmanipulated) face photographs were flirting with their romantic partner. Facial femininity was assessed using objective analyses of shape and via third-party ratings of facial femininity. For heterosexual participants, women reported significantly greater jealousy when imagining more feminine women flirting with their romantic partner. This pattern of results was also seen for lesbian participants, although the correlation between rival femininity and jealousy was significantly weaker for lesbian participants than it was for heterosexual participants. Collectively, these results present further evidence that facial femininity of potential rivals influences women’s reported jealousy, particularly in heterosexual women, and is further evidence for the proposal that putative markers of the mate value of rivals play a role in women’s jealousy.
Deep-sea gas hydrate mounds and chemosynthetic fauna discovered at 3640 m on the Molloy Ridge, Greenland Sea
Abstract Methane seepage at the seafloor can form gas hydrate and sustain chemosynthetic communities of deep-sea animals. Most known hydrate seeps occur shallower than 2000 m on continental slopes, whereas hydrothermal vents are found at greater depths along active spreading centres. Here we report the discovery of hydrate mounds with cold-seep fauna at 3640 m deep on the Molloy Ridge. The mounds display seafloor morphologies resulting from progressive stages of hydrate dissociation. Gas bubbles from the mounds rise to within 300 m of the ocean surface, and isotopic analysis shows the hydrates contain thermogenic gas. Crude oil sampled from the hydrate deposits indicates a young Miocene source rock formed in a fresh-brackish water paleo-environment. The hydrate mounds are inhabited by taxa including siboglinid and maldanid tubeworms, skeneid and rissoid snails, and melitid amphipods. Family-level composition of the fauna is similar to that of Arctic hydrothermal vents at similar depths, including the Jøtul vent field on the Knipovich Ridge, and less similar to nearby methane seeps at shallower depths. The overlap between seep and vent fauna in the Arctic has implications for understanding ecological connectivity across deep-sea habitats and assessing their vulnerability to future impacts from seafloor resource extraction in the region.
PD-1/PD-L1 pathway relieves incision induced acute postoperative pain via inhibiting the neuroinflammation in dorsal root ganglion of rats
Abstract Acute postoperative pain represents a significant clinical challenge, yet its underlying mechanisms remain incompletely understood. A previous study found that PD-1/PD-L1can relieve chronic pain. Mechanical withdrawal thresholds (MWT) and thermal withdrawal latency (TWL) were quantified in rats at baseline (pre-incision) and at postoperative timepoints of 2, 8, and 24 h. Concurrently, PD-1/PD-L1 expression levels and neuroinflammatory markers were assessed at the 24-hour terminal timepoint. PD-1 inhibitors and agonists were administered via intrathecal injection immediately after surgical incision and at 12 h postoperatively, respectively. It was found that incision surgery resulted in significant postoperative pain accompanied by upregulation of PD-1/PD-L1 and neuroinflammation. Inhibition of PD-1 expression could further exacerbate acute postoperative pain by upregulating neuroinflammation, whereas upregulation of PD-1 expression could alleviate acute postoperative pain by inhibiting neuroinflammation. Activation of the PD-1/PD-L1 pathway relieves acute postoperative pain induced by plantar incision. This may be a therapeutic target for acute postoperative pain.

Genotyping by sequencing reveals a chromosome A04 QTL governing whitefly resistance in upland cotton
Abstract Cotton plants utilize physical defenses such as trichomes and leaf characteristics to deter insect pests and environmental stressors, safeguarding their growth and productivity. Cotton insect pests such as whiteflies, aphids, jassids and boll weevils not only directly damage the crop but also transmit harmful viruses, leading to substantial yield and quality loss. A GBS study was conducted on 206 cotton plants from a cross between whitefly resistant and whitefly susceptible varieties to identify genetic markers linked to whitefly resistance and yield traits. This study identified genetic regions associated with whitefly resistance and yield traits, including specific genes on chromosomes A04 and D09 linked to resistance mechanisms and flower number, respectively. This study identified genes involved in whitefly resistance ( At4g27190 and RPPL1 ) and genes linked to increased flowering and plant vigor (GUS1, MBD4L), paving the way for the development of molecular marker-assisted breeding to create resilient cotton cultivars.
