The “warm” data in the middle, such as your old photos, can take a few seconds to retrieve. Most data is cold, and a lot of it could probably be erased without consequence. Yet some of it might one ...

The use of magnetic beads as a new DNA extraction tool shows numerous benefits compared to traditional extraction methods. The large specific surface area of magnetic beads makes them effective at ...

which served as a foundation for adding shorter DNA strands. This process was akin to threading beads onto a string. Researchers then used a chemical reaction to attach a methyl group (CH3), a ...

Preparation of Chitosan@Beads. A: schematic diagram of chitosan-modified magnetic nanobeads; B: Schematic diagram of Chitosan@Beads modification steps. Disclaimer: AAAS and EurekAlert! are not ...

Dynabeads magnetic beads have played and continue to play an important role in the workflow from the isolation of trace amounts of ancient DNA to obtaining high-quality sequencing data.

Researchers first collect images of an array of DNA-barcoded beads on a slide, creating a reference that tells the location of each bead. Next, they place a tissue section on the beads and ...

Some histones function as spools for the thread-like DNA to wrap around. Under the microscope in its extended form, chromatin looks like beads on a string. The beads are called nucleosomes.
