A replication of Metalsky, Halberstadt & Abramson's (1987) test of the revised hopelessness model of depression was conducted. Depressive mood response to examination outcome was assessed in undergraduate students across two periods of examination. In phase 1, consistent with Metalsky et al. (1987), examination outcome was the sole predictor of depressive mood response on receipt of exam results. There was no evidence for a delayed mood response five days later. In phase 2, the interaction between attributional style and exam outcome was predictive of depressive mood response on receipt of exam results. Taken together, the results provide support for the diathesis-stress and specific vulnerability components of the model with respect to immediate mood response. No support was found for the causal mediation component. Differences between recently published studies are reported and implications for the model discussed.

Under current climate change patterns, rapidly changing environments can impose strong selection on traits. Costly traits that require heavy investment and strongly affect fitness may be particularly vulnerable to such changes. Despite organisms experiencing dynamic environments, our knowledge of costly trait response is limited as longitudinal studies across generations are rare.

The reward responsivity hypothesis of self-control proposes that, irrespective of self-control success, exercising self-control is aversive and engenders negative affect. To countermand this discomfort, reward-seeking behavior may be amplified after bouts of self-control, bringing individuals back to a mildly positive baseline state. Previous studies indicated that effort-an integral component of self-control-can increase reward responsivity.

Social comparisons are a core feature of human life. Theories posit that social comparisons play a critical role in depression and social anxiety triggering negative evaluations about the self, as well as negative emotions. We investigated the neural basis of social comparisons in participants with depression and/or social anxiety (MD-SA, n=56) and healthy controls (n=47) using functional magnetic resonance imaging (fMRI).

Solitary foraging insects like desert ants rely heavily on vision for navigation. While ants can learn visual scenes, it is unclear what cues they use to decide if a scene is worth exploring at the first place. To investigate this, we recorded the motor behavior of Cataglyphis velox ants navigating in a virtual reality set-up (VR) and measured their lateral oscillations in response to various unfamiliar visual scenes under both closed-loop and open-loop conditions.

The gene is nearly ubiquitously subjected to activating mutation in pancreatic adenocarcinomas (PDAC), occurring at a frequency of over 90% in tumors. Mutant KRAS drives sustained signaling through the MAPK pathway to affect frequently disrupted cancer phenotypes including transcription, proliferation and cell survival. Recent research has shown that PDAC tumor growth and survival required a guanine nucleotide exchange factor for RAS homolog family member A (RhoA) called GEF-H1.
