Effect of Virtual Reality Perspective-Taking on Related and Unrelated Contexts.

Virtual reality perspective-taking (VRPT) experiences effectively increase both empathy and prosocial behaviors toward related social targets (e.g., cutting down a tree in virtual reality increases concern for the environment).

Identification of a vacuolar proton channel that triggers the bioluminescent flash in dinoflagellates.

In 1972, J. Woodland Hastings and colleagues predicted the existence of a proton selective channel (HV1) that opens in response to depolarizing voltage across the vacuole membrane of bioluminescent dinoflagellates and conducts protons into specialized luminescence compartments (scintillons), thereby causing a pH drop that triggers light emission. HV1 channels were subsequently identified and demonstrated to have important functions in a multitude of eukaryotic cells.

Utilizing usernames for sex categorization in computer-mediated communication: examining perceptions and accuracy.

As more interpersonal interactions move online, people increasingly get to know and recognize one another by their self-selected identifiers called usernames. Early research predicted that the lack of available cues in text based computer-mediated communication (CMC) would make primitive categories such as biological sex irrelevant in online interactions. Little is known about the types of perceptions people make about one another based on this information, but some limited research has shown that questions about gender are the first to be asked in online interactions and sex categorization has maintained salience.

Regulatory role of the C-terminus of the epsilon subunit from the chloroplast ATP synthase.

The ATP synthases from chloroplasts and Escherichia coli are regulated by several factors, one of which is the epsilon subunit. This small subunit is also required for ATP synthesis. Thylakoid membranes reconstituted with CF1 lacking the epsilon subunit (CF1-epsilon) exhibit no ATP synthesis and very high ATP hydrolysis.

The C-terminal domain of the epsilon subunit of the chloroplast ATP synthase is not required for ATP synthesis.

The epsilon subunit of the ATP synthases from chloroplasts and Escherichia coli regulates the activity of the enzyme and is required for ATP synthesis. The epsilon subunit is not required for the binding of the catalytic portion of the chloroplast ATP synthase (CF1) to the membrane-embedded part (CFo). Thylakoid membranes reconstituted with CF1 lacking its epsilon subunit (CF1-epsilon) have high ATPase activity and no ATP synthesis activity, at least in part because the membranes are very leaky to protons.
