Visual information emerging from the extrafoveal locations is important for visual search, saccadic eye movement control, and spatial attention allocation. Our everyday sensory experience with visual object categories varies across different parts of the visual field which may result in location-contingent variations in visual object recognition. We used a body, animal body, and chair two-forced choice object category recognition task to investigate this possibility.

Gene Expression After Exercise Is Disrupted by Early-Life Stress.

Dev Psychobiol

January 2025

Department of Psychological & Brain Sciences, University of Delaware, Newark, Delaware, USA.

Exercise can be leveraged as an important tool to improve neural and psychological health, either on its own or to bolster the efficacy of evidence-based treatment modalities. Research in both humans and animal models shows that positive experiences, such as exercise, promote neuroprotection while, in contrast, aversive experiences, particularly those in early development, are often neurologically and psychologically disruptive. In the current study, we employed a preclinical model to investigate the therapeutic benefits of exercise on gene expression in the brains of adult rats.

Improving future agricultural sustainability by optimizing crop distributions in China.

PNAS Nexus

January 2025

Department of Geosciences and Natural Resource Management, University of Copenhagen, DK-1350 Copenhagen, Denmark.

Improving agricultural sustainability is a global challenge, particularly for China's high-input and low-efficiency cropping systems with environmental tradeoffs. Although national strategies have been implemented to achieve Sustainable Development Goals in agriculture, the potential contributions of crop switching as a promising solution under varying future climate change are still under-explored. Here, we optimize cropping patterns spatially with the targets of enhancing agriculture production, reducing environmental burdens, and achieving sustainable fertilization across different climate scenarios.

The SARS-CoV-2 main protease (M or Nsp5) is critical for production of viral proteins during infection and, like many viral proteases, also targets host proteins to subvert their cellular functions. Here, we show that the human tRNA methyltransferase TRMT1 is recognized and cleaved by SARS-CoV-2 M. TRMT1 installs the ,-dimethylguanosine (m2,2G) modification on mammalian tRNAs, which promotes cellular protein synthesis and redox homeostasis.

The endothelin-B receptor (ETR) mediates vasodilation in young women, an effect that is absent in postmenopausal women. We have previously demonstrated that ETR-mediated vasodilation is regulated by estradiol (E) in young women; however, the impact of E on ETR function in postmenopausal women remains unknown. Accordingly, the objective of this study was to test the hypothesis that E exposure restores ETR-mediated dilation in postmenopausal women.

Mammalian red blood cells are generated via a terminal erythroid differentiation pathway culminating in cell polarization and enucleation. Actin filament polymerization is critical for enucleation, but the molecular regulatory mechanisms remain poorly understood. We utilized publicly available RNA-seq and proteomics datasets to mine for actin-binding proteins and actin-nucleation factors differentially expressed during human erythroid differentiation and discovered that a focal adhesion protein-Tensin-1-dramatically increases in expression late in differentiation.

Triple-negative breast cancer (TNBC) is infamous for its aggressive phenotype and poorer prognosis when compared to other breast cancer subtypes. One factor contributing to this poor prognosis is that TNBC lacks expression of the receptors that available hormonal or molecular-oriented therapies attack. New treatments that exploit biological targets specific to TNBC are desperately needed to improve patient outcomes.

Article Synopsis
  • Many agricultural watersheds depend on voluntary management practices (MPs) to improve water quality by reducing nutrient and sediment runoff, but the effectiveness of these practices is unclear.
  • Analysis of water-quality data from three prioritized Chesapeake Bay watersheds (Smith Creek, Upper Chester River, and Conewago Creek) from 1985 to 2020 reveals inconsistent outcomes, with some areas seeing no decrease in nutrient or sediment loads despite an increase in MPs.
  • The study suggests that while MPs may have prevented further water-quality decline, real improvements will likely require lowering manure and fertilizer applications, underscoring the need for long-term monitoring to evaluate MP effectiveness.
