Effects of acute cooling and bradycardia on central venous pressure and cardiac function in Nile tilapia (Oreochromis niloticus).

We developed and validated a surgical technique to measure central venous pressure (CVP) in Nile tilapia, and investigated the effects of an acute temperature decrease (from 30 vs. 24 °C) and changes in heart rate (f) using zatebradine hydrocholoride, which decreases intrinsic f on this species' cardiac function. As predicted, f and cardiac output ( ) were ~ 40% lower in the acutely cooled fish, and both groups had very comparable (i.

Improving debriefing practices for participants in social science experiments.

Social science experiments often expose participants to false, deceptive, or otherwise harmful content. In an effort to mitigate the effects of such content and to comply with regulatory standards, these studies usually conclude by "debriefing" participants about the content they encountered, on the assumption that doing so will eliminate the effects of exposure. We present evidence showing that this assumption is not always correct.

Correcting misinformation about the Russia-Ukraine War reduces false beliefs but does not change views about the War.

We report results from simultaneous experiments conducted in late 2022 in Belarus, Estonia, Kazakhstan, Russia and Ukraine. The experiments focus on fact-checking misinformation supportive of Russia in the Russia-Ukraine War. Meta-analysis makes clear that fact-checking misinformation reduces belief in pro-Kremlin false claims.
