INTEGRA, BioTools and Sullivan Nicolaides Pathology work together to accelerate COVID-19 testing

The global COVID-19 pandemic has placed unprecedented demands on pathology services to test patient samples for the novel SARS-CoV-2 coronavirus alongside their pre-existing respiratory virus panels. This extreme influx of samples quickly exhausted the capacity of existing systems in the Microbiology and Molecular Pathology Department at Sullivan Nicolaides Pathology (SNP).

High-Speed, High-Throughput Cell Counting for Concentration and Viability

A high-throughput automated cell counting system, the Cellaca MX is able to image, analyze, and report cell concentration and viability for 24 samples in 48 seconds, by using bright field (trypan blue), and in 2.5 minutes by using several fluorescent imaging channels.

Study shows different cell response offers more control to muscles

Slight variations in individual muscle cell contractions enable the whole muscle to bend with more precision and control.

	New cell atlas can help control mosquito-borne diseases The first cell atlas of mosquito immune cells recently created by researchers can help interpret how mosquitoes combat various infections, including malaria.

	Proteins act as compasses to guide stem cell division in plants The stem cells tasked with creating and maintaining biological tissues have a difficult job. They have to precisely divide to form new specialized cells, which are destined to different fates even though they contain identical DNA. An obvious question then is: How do the cells divide in all the right ways to produce a healthy tissue?

	T-cell-based vaccine strategy provides broader protection against influenza As Americans begin pulling up their sleeves for an annual flu vaccine, researchers at the University of Wisconsin-Madison have provided new insights into an alternative vaccine approach that provides broader protection against seasonal influenza.

	Researchers discover a mechanism that leads to the growth of cell nuclei By far the most important process in cell development is how cells divide and then enlarge in order to multiply. A research team headed by Freiburg medical scientist Prof. Dr. Robert Grosse has now discovered that bundled fibers of actin within a cell nucleus play an important part in how they enlarge after division.

	New findings overturn the understanding of cholesterol’s impact on cell membranes For more than a decade, scientists have accepted that cholesterol - a key component of cell membranes - did not uniformly affect membranes of different types.
