One of the best ways to study human evolution is by comparing us with nonhuman species that, evolutionarily speaking, are closely related to us. That closeness can help scientists narrow down precisely what makes us human, but that scope is so narrow it can also be extremely hard to define. To address this complication, researchers from Stanford University have developed a new technique for comparing genetic differences.
Through two separate sets of experiments with this technique, the researchers discovered new genetic differences between humans and chimpanzees. They found a significant disparity in the expression of the gene SSTR2 - which modulates the activity of neurons in the cerebral cortex and has been linked, in humans, to certain neuropsychiatric diseases such as Alzheimer s dementia and schizophrenia - and the gene EVC2, which is related to facial shape. The results were published March 17 in
Emory MVA COVID-19 Vaccine Safe in Animal Models by Colleen Fleiss on February 6, 2021 at 3:02 AM
In mice and monkeys, Emory MVA COVID-19 vaccine has proven safe and effective, said Yerkes National Primate Research Center, Emory University researchers. Results from this National Institute of Allergy and Infectious Diseases (NIAID)-funded study are published online today in Immunity.
Like the Moderna and Pfizer COVID-19 vaccines, the Emory MVA COVID-19 vaccine induces strong neutralizing antibodies, which support the immune system s ability to fight infections. The Emory MVA COVID-19 takes protection several steps further, starting with inducing killer CD8 T cells in addition to the neutralizing antibodies, providing a multi-pronged approach to halting SAR-COV-2.
I am a graduate student at the State University of New York, Albany in the Gaesser Lab. I am broadly interested in the intersection of social cognition, morality, and memory and imagination. My specific interests include empathy and its influence on morality as well as the role of imagination in the formation and maintenance of social bonds. Prior to SUNY Albany, I attended Emory University where I began as an undergraduate research assistant at Yerkes National Primate Research Center.
