The War On Higher Education, Athena D. Mutua, Jonathan Feingold, Angela Harris, Emily M. S. Houh, Matthew Patrick Shaw, Francisco Valdes

Journal Articles

Higher education is under assault in the United States. Tracking authoritarian movements across the globe, domestic attacks on individual professors and academic institutions buttress a broader campaign to undermine multiracial democracy and the institutions that sustain and safeguard it. Reflecting on the past academic year, this essay charts the increasingly brazen right-wing efforts in the U.S. Congress and the States to erode academic freedom and university independence— two pillars of our democratic republic. We also identify a bi-partisan source of higher education’s present precarity: the neoliberal policies that precipitated the privatization and corporatization of universities across the country.

Dissenting Authority, Guyora Binder

Journal Articles

This essay explicates J.B. White’s rhetorical conception of authority as a potentially collaborative achievement and contrasts it with the conception of authority as surrender of judgment prevailing in legal philosophy. On White’s view, authority is not an instrument held and deployed, but is conferred, like respect. This conception of authority illuminates three puzzles concerning the relationship between dissent and legal authority. First, Legal Positivism’s purportedly descriptive account of law insists it must claim an authority to govern independent of justice and assent. Yet law’s language is replete with justice-based appeals for popular assent. White’s reading of the practice of legal …

Dynamin-related protein 1 (DRP1) plays crucial roles in mitochondrial and peroxisome fission. However, the mechanisms underlying the functional regulation of DRP1 in adipose tissue during obesity remain unclear. To elucidate the metabolic and pathological significance of diminished DRP1 in obese adipose tissue, we utilized adipose tissue-specific DRP1 KO mice challenged with a high-fat diet. We observed significant metabolic dysregulations in the KO mice. Mechanistically, DRP1 exerts multifaceted functions in mitochondrial dynamics and endoplasmic reticulum (ER)-lipid droplet crosstalk in normal mice. Loss of function of DRP1 resulted in abnormally giant mitochondrial shapes, distorted mitochondrial membrane structure, and disrupted cristae architecture. Meanwhile, …

Faculty, Staff and Student Publications

Drug discovery relies on efficient identification of small-molecule leads and their interactions with macromolecular targets. However, understanding how chemotypes impact mechanistically important conformational states often remains secondary among high-throughput discovery methods. Here, we present a conformational discovery pipeline integrating time-resolved, high-throughput small-angle X-ray scattering (TR-HT-SAXS) and classic fragment screening applied to allosteric states of the mitochondrial import oxidoreductase apoptosis-inducing factor (AIF). By monitoring oxidized and X-ray-reduced AIF states, TR-HT-SAXS leverages structure and kinetics to generate a multidimensional screening dataset that identifies fragment chemotypes allosterically stimulating AIF dimerization. Fragment-induced dimerization rates, quantified with time-resolved SAXS similarity analysis (k

Dopaminergic Neurons In Zona Incerta Drives Appetitive Self-Grooming, Zhiying Jiang, Michelle He, Claire Young, Jing Cai, Yuanzhong Xu, Yanyan Jiang, Hongli Li, Maojie Yang, Qingchun Tong

Faculty, Staff and Student Publications

Dopaminergic (DA) neurons are known to play a key role in controlling behaviors. While DA neurons in other brain regions are extensively characterized, those in zona incerta (ZITH or A13) receive much less attention and their function remains to be defined. Here it is shown that optogenetic stimulation of these neurons elicited intensive self‐grooming behaviors and promoted place preference, which can be enhanced by training but cannot be converted into contextual memory. Interestingly, the same stimulation increased DA release to periaqueductal grey (PAG) neurons and local PAG antagonism of DA action reduced the elicited self‐grooming. In addition, A13 neurons increased …

Oncogenic mutations are abundant in the tissues of healthy individuals, but rarely form tumours1-3. Yet, the underlying protection mechanisms are largely unknown. To resolve these mechanisms in mouse mammary tissue, we use lineage tracing to map the fate of wild-type and Brca1-/-;Trp53-/- cells, and find that both follow a similar pattern of loss and spread within ducts. Clonal analysis reveals that ducts consist of small repetitive units of self-renewing cells that give rise to short-lived descendants. This offers a first layer of protection as any descendants, including oncogenic mutant cells, are constantly lost, thereby limiting the spread of mutations to …
