https://www.selleckchem.com/ COVID-19 has unfortunately halted lab work, conferences, and in-person networking, which is especially detrimental to researchers just starting their labs. Through social media and our reviewer networks, we met some early-career stem cell investigators impacted by the closures. Here, they introduce themselves and their research to our readers.Direct cell fate conversion of human somatic cells into induced neurons (iNs) is often regarded as a highly concerted one-step process. In this issue of Cell Stem Cell, Cates et al. (2021) dissect the iN conversion trajectory into two largely independent steps and identify key players at each stage.2021 marks the 30th anniversary of the revelation that cyclosporin A and FK506 act in a way previously not seen-as "molecular glues" that induce neo-protein-protein associations. As a torrent of new molecular-glue probes and medicines are fueling interest in this field, I explore the arc of this story.Hardwired circuits encoding innate responses have emerged as an essential feature of the mammalian brain. Sweet and bitter evoke opposing predetermined behaviors. Sweet drives appetitive responses and consumption of energy-rich food sources, whereas bitter prevents ingestion of toxic chemicals. Here we identified and characterized the neurons in the brainstem that transmit sweet and bitter signals from the tongue to the cortex. Next we examined how the brain modulates this hardwired circuit to control taste behaviors. We dissect the basis for bitter-evoked suppression of sweet taste and show that the taste cortex and amygdala exert strong positive and negative feedback onto incoming bitter and sweet signals in the brainstem. Finally we demonstrate that blocking the feedback markedly alters responses to ethologically relevant taste stimuli. These results illustrate how hardwired circuits can be finely regulated by top-down control and reveal the neural basis of an indispensable behavioral response for all ani
