Unlabelled: Biomolecular condensates organize cellular environments and regulate key processes such as transcription. We previously showed that full-length androgen receptor (AR-FL), a major oncogenic driver in prostate cancer (PCa), forms nuclear condensates upon androgen stimulation in androgen-sensitive PCa cells. Disrupting these condensates impairs AR-FL transcriptional activity, highlighting their functional importance.

Electron Microscopy Reveals Inhomogeneous Adsorption of Iodine and Concurrent Defect Formation in a Metal-Organic Framework.

Adsorption behaviors are typically examined through adsorption isotherms, which measure the average adsorption amount as a function of partial pressure or time. However, this method is incapable of identifying inhomogeneities across the adsorbent, which may occur in the presence of strong intermolecular interactions of the adsorbate. In this study, we visualize the adsorption of molecular iodine (I) in the metal-organic framework material MFM-300(Sc) using high-resolution scanning transmission electron microscopy (STEM).

Unlabelled: Since the inception of transplantation, it has been crucial to ensure that organ or tissue donations are made with valid informed consent to avoid concerns about coercion or exploitation. This issue is particularly challenging when it comes to infants and younger children, insofar as they are unable to provide consent. Despite their vulnerability, infants' organs and tissues are considered valuable for biomedical purposes due to their size and unique properties.

The snub-nosed, reclining, and serene image of the fetus is commonplace in cultural representations and analyses of obstetric ultrasound. Yet following the provocation of various feminist scholars, taking the fetal sonogram as the automatic object of concern vis-à-vis ultrasound cedes ground to anti-abortionists, who deploy fetal images to argue that life begins at conception and that the unborn are rights bearing subjects who must be protected. How might feminists escape this analytical trap, where discussions of ultrasonics must always be engaged in the act of debunking? This article orients away from the problem of fetal representation by employing a method which may appear to be wildly unsuitable: media archaeology.
