We describe a protocol for the fabrication of microfluidic devices that can enable cell capture and culture. In this approach patterned microstructures such as grooves within microfluidic channels are used to create low shear stress regions within which cell can dock.

Minor Losses in Pipes

In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively. Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...

A Minority of One: Conformity to Group Norms

Source: William Brady & Jay Van Bavel—New York University It is obvious that we are influenced by those around us, but in the early to mid 1900's, psychologists began to study how potent social influence can be on our thoughts and behaviors. Motivated in part by attempts to explain the behaviors of Nazi soldiers in World War II, one topic of considerable interest at the time in psychology was conformity, the phenomenon in which people match their attitudes, behaviors, or beliefs to group...

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Gram-negative bacteria produce two spatially segregated membranes. The outer membrane is partitioned from the inner membrane by a periplasm and a peptidoglycan layer. The ability to isolate the dual bilayers of these microbes has been critical for understanding their physiology and pathogenesis.
FAQs
AT-rich regions often form especially narrow minor grooves, creating a distinctive structural feature along the DNA surface. That narrowing can help proteins or small molecules recognize a sequence through shape-based interactions, in addition to direct chemical contacts. Consequently, sequence composition may influence where minor-groove-binding interactions occur and how selectively they are established.
Recognition combines several complementary signals rather than relying on a single contact. Hydrogen bonding can connect interacting molecules with chemical features of base pairs, while van der Waals forces contribute close-range attraction. Shape-based interactions allow recognition of groove geometry. Together, these mechanisms help explain how proteins and small molecules distinguish DNA sites without strand separation.
The groove's width and shape determine the physical surface presented to a binding partner, while hydration describes associated water structure and electrostatic properties affect charge-based attraction. Changes in these features can alter how readily proteins or small molecules fit, contact, and stabilize at a DNA site. These variables therefore influence recognition strength and selectivity.
Transcription factors can use minor-groove features to identify particular DNA regions, linking local molecular recognition with gene regulation. Because the groove presents both chemical information and structural cues, binding need not depend only on strand separation. This makes minor-groove interactions relevant to how regulatory proteins associate with DNA and helps explain their importance in transcription-related processes.
Minor-groove interactions contribute to several stages of DNA handling in cells, including packaging, replication, and repair. In each context, access to base-pair features on the helix surface can provide information for proteins that work with DNA. Studying these interactions therefore connects local groove recognition with broader questions about genome organization and the maintenance of genetic material.
Characterizing how sequence, groove shape, hydration, and electrostatic properties influence interactions can inform the design of sequence-selective drugs and molecular probes. Such tools can support research on DNA recognition and help investigate gene regulation and genome organization. This application turns structural features of the helix into practical targets for studying biological function.
