Putting cells through their paces

The spheroid is the width of a few human hairs and made up of 25,000 human lung cells clustered together with iron particle, suspended in a fluid that runs though a microscopic obstacle course of channels sealed between glass.

How anthrax spores grow in cultured human tissues

Cultured human lung cells infected with a benign version of anthrax spores have yielded insights into how anthrax grows and spreads in exposed people. The study, published in the Journal of Applied Microbiology, will help ...

Flipping the 'off' switch on cell growth

A protein known for turning on genes to help cells survive low-oxygen conditions also slows down the copying of new DNA strands, thus shutting down the growth of new cells, Johns Hopkins researchers report. Their discovery ...

Nickel nanoparticles may contribute to lung cancer

All the excitement about nanotechnology comes down to this: Structures of materials at the scale of billionths of a meter take on unusual properties. Technologists often focus on the happier among these newfound capabilities, ...
