Distinct cellular and junctional dynamics independently regulate the rotation and elongation of the embryonic gut in Drosophila

by Mikiko Inaki, Takamasa Higashi, Satoru Okuda, Kenji Matsuno

Complex organ structures are formed with high reproducibility. To achieve such intricate morphologies, the responsible epithelium undergoes multiple simultaneous shape changes, such as elongation and folding. However, these changes have typically been assessed separately. In this study, we revealed how distinct shape changes are controlled during internal organ morphogenesis. The Drosophila embryonic hindgut undergoes left-right... Читать дальше...

Reverse-engineered models reveal differential membrane properties of autonomic and cutaneous unmyelinated fibers

by Brandon J. Thio, Nathan D. Titus, Nicole A. Pelot, Warren M. Grill

Unmyelinated C-fibers constitute the vast majority of axons in peripheral nerves and play key roles in homeostasis and signaling pain. However, little is known about their ion channel expression, which controls their firing properties. Also, because of their small diameters (~ 1 μm), it has not been possible to characterize their membrane properties using voltage clamp. We developed a novel library of isoform-specific ion...

BoReMi: Bokeh-based jupyter-interface for registering spatio-molecular data to related microscopy images

by Jaspreet Ishar, Yee Man Tam, Simon Mages, Johanna Klughammer

Spatio-molecular data and microscopy images provide complementary information, essential to study structure and function of spatially organised multicellular systems such as healthy or diseased tissues. However, aligning these two types of data can be challenging due to distortions and differences in resolution, orientation, and position. Manual registration is tedious but may be necessary for challenging samples as well as for... Читать дальше...

The Mirage of Honest Government

America is always on the verge of finally having "honest government." Of course, what passes for “honest government” is a government that efficiently takes wealth from productive people and transfers it to those who are politically-connected.

Historic Short Squeeze Sends Oil Prices Higher

Last weekend, we warned readers that according to the latest data from Goldman Sachs,  a massive short squeeze in energy stocks was on deck. Specifically we noted that at a time when funds were the most short oil on record, the broader energy space "was the most net sold sector" on the Goldman US Prime book, "driven entirely by short sales, which outpaced long buys (6.4 to 1)." And here, we said, was "the hint to the next mega squeeze" as the recent short selling in energy was the largest in over 5 years. Читать дальше...

The optimal spatially-dependent control measures to effectively and economically eliminate emerging infectious diseases

by Fan Xia, Yanni Xiao, Junling Ma

Non-pharmaceutical interventions (NPIs) are effective in mitigating infections during the early stages of an infectious disease outbreak. However, these measures incur significant economic and livelihood costs. To address this, we developed an optimal control framework aimed at identifying strategies that minimize such costs while ensuring full control of a cross-regional outbreak of emerging infectious diseases. Our approach uses a spatial SEIR model with interventions for the epidemic process... Читать дальше...

RNAtango: Analysing and comparing RNA 3D structures via torsional angles

by Marta Mackowiak, Bartosz Adamczyk, Marta Szachniuk, Tomasz Zok

RNA molecules, essential for viruses and living organisms, derive their pivotal functions from intricate 3D structures. To understand these structures, one can analyze torsion and pseudo-torsion angles, which describe rotations around bonds, whether real or virtual, thus capturing the RNA conformational flexibility. Such an analysis has been made possible by RNAtango, a web server introduced in this paper, that provides a trigonometric perspective on RNA 3D structures... Читать дальше...
