Antarctic cushion star Odontaster validus larval performance is negatively impacted by long-term parental acclimation to elevated temperature.

Cross-generational responses, when the parents' environment influences offspring performance, may contribute to species resilience to climate change in rapidly warming regions such as coastal Antarctica. Adult Antarctic sea stars Odontaster validus were conditioned in the laboratory to two temperature treatments (ambient, 0 °C and warming, +3 °C) for two years, and their gametes were used to generate larval offspring. The response of their larvae to five temperatures (0 °C, 1 °C, 2 °C, 3 °C, and 4 °C) was examined over 145 days.

Effects of wearing a surgical face mask on cognitive functioning and mood states: a randomised controlled trial in young adults.

Despite significant public concerns voiced about wearing face masks and reports from healthcare workers of adverse effects on cognition, research into potential adverse effects remains limited. The present trial investigated the effects of wearing a surgical face mask for prolonged periods on cognitive functioning and mood. We tested 42 university students (18-36 years old) using a controlled counterbalanced crossover design that involved a mask session and a control session, separated by 1 week.

Comparison of Taboo Search Methods for Atomic Cluster Global Optimization with a Basin-Hopping Algorithm.

The basin-hopping algorithm (BHA) allows for the efficient exploration of atomic cluster potential energy surfaces by random perturbations in configuration space, followed by energy minimizations. Here, the taboo search method is incorporated to prevent the search from revisiting recently visited regions of the search space. Two taboo search modes are implemented, one mode resets the search to random coordinates upon encountering the taboo region, while the other simply rejects any proposed move into the taboo region.

Activin B and Activin C Have Opposing Effects on Prostate Cancer Progression and Cell Growth.

Current prognostic and diagnostic tests for prostate cancer are not able to accurately distinguish between aggressive and latent cancer. Members of the transforming growth factor-β (TGFB) family are known to be important in regulating prostate cell growth and some have been shown to be dysregulated in prostate cancer. Therefore, the aims of this study were to examine expression of TGFB family members in primary prostate tumour tissue and the phenotypic effect of activins on prostate cell growth.

Emotional information processing in young and older adults: meta-analysis reveals faces elicit distinct biases.

Unlabelled: Although a number of empirical studies have found support for distinct emotional information processing biases in young versus older adults, it remains unclear whether these biases are driven by differential processing of positive or negative emotional information (or both) and whether they are moderated by stimulus type, in particular face versus non-face, the former of which is known to be subject to distinct processing. To address these gaps in the literature, our analyses included 2237 younger (mean age = 21.61 years) and 2136 older (mean age = 70.
