CRISPR-Cas12a-Assisted DNA Circuit for Nonmicroscopic Detection of Cell Surface Receptor Clustering.

Protein-protein interactions (PPIs) on the cell surface have been of great interest due to their high clinical relevance and significance; however, the methods for detecting PPIs heavily rely on microscopic instruments. In this work, we designed a Cas12a-assisted DNA circuit for detecting cell surface receptor clustering events without a dependence on microscopy. This nonmicroscopic approach is based on the proximity principle, where localized protein-protein interactions such as receptor clustering are converted into DNA barcodes.

A luminous and young galaxy at = 12.33 revealed by a JWST/MIRI detection of Hα and [O iii].

The James Webb Space Telescope has discovered a surprising population of bright galaxies in the very early Universe (≲500 Myr after the Big Bang) that is hard to explain with conventional galaxy-formation models and whose physical properties are not fully understood. Insight into their internal physics is best captured through nebular lines, but at these early epochs, the brightest of these spectral features are redshifted into the mid-infrared and remain elusive. Using the mid-infrared instrument onboard the James Webb Space Telescope, here we present a detection of Hα and doubly ionized oxygen ([O iii] 4959,5007 Å) from the bright, ultra-high-redshift galaxy candidate GHZ2/GLASS-z12.

Store-operated Ca entry is involved in endothelium-to-mesenchymal transition in lung vascular endothelial cells.

Unlabelled: Endothelial-to-mesenchymal transition (EndMT) is a biological process that converts endothelial cells to mesenchymal cells with increased proliferative and migrative abilities. EndMT has been implicated in the development of pulmonary vascular remodeling in pulmonary arterial hypertension (PAH), a fatal and progressive lung vascular disease. Transforming growth factor β (TGF-β ), an inflammatory cytokine, is known to induce EndMT in many types of endothelial cells including lung vascular endothelial cells (LVEC).

Digestate Improves Stinging Nettle () Growth and Fiber Production at a Chlor-Alkali Site.

Marginal lands have been proposed to produce non-food crop biomass for energy or green materials. For this purpose, the selection, implementation, and growth optimization of plant species on such lands are key elements to investigate to achieve relevant plant yields. Stinging nettle () is a herbaceous perennial that grows spontaneously on contaminated lands and was described as suitable to produce fibers for material applications.

Robust Sequence Design Space for the Isothermal Exponential Amplification of Short Oligonucleotides.

Advances in isothermal amplification techniques have accelerated development in biosensing applications and the design of complex molecular devices. The exponential amplification reaction technique, or EXPAR, is uniquely positioned to process molecular information from short oligonucleotide strands (≈10 nucleotides length) typically encountered in molecular computing or microRNA detection. Despite its conceptual simplicity (requiring only a template strand and two enzymes), the issue of nonspecific background amplification has hindered broader adoption.
