Making Things Grow: Insect Cells, Stem Cells, and Primary Cell Lines All Pose Challenges for Cell Culturists
Laura Defrancesco | Jun 21, 1998 | 5 min read
Date: June 22, 1998 Insect Cell Culture Media, Suppliers of Primary Cell Culture Media Advantages for Protein Expression Studies Since the mid-1950s cultures of insects--cockroaches, fruit flies, and leafhoppers, to name a few--have been the object of quiet study by physiologists and cell biologists. But along came genetic engineering and suddenly insect cultures have been put in the spotlight since they provide advantages over both bacterial and mammalian systems for recombinant protein prod
Bacteria Harbor Geometric “Organelles”
Amber Dance | Dec 1, 2018 | 10+ min read
Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.

©Mehau Kulyk/Photo Researchers, IncToward the end of World War II, a German-imposed food embargo in western Holland – a densely populated area already suffering from scarce food supplies, ruined agricultural lands, and the onset of an unusually harsh winter – led to the death by starvation of some 30,000 people. Detailed birth records collected during that so-called Dutch Hunger Winter have provided scientists with useful data for analyzing the long-term health effects of prenat
