Single-Celled Fungi Multiply, Alien-Like, by Fusing Cells in Host

Microsporidia cause diarrhea, an illness called microsporidiosis and even death in immune-compromised individuals.

In spite of those widespread medical problems, scientists were uncertain about how these single-celled fungi reproduced in human or animal cells.

But in a study that employed transparent roundworms, biologists at the University of California San Diego succeeded in directly observing how these microorganisms replicate and spread. And what they saw surprised them.

Biologists Create Malaria-Blocking Mosquitoes

Using a groundbreaking gene editing technique, biologists at UC San Diego, working in collaboration with biologists at UC Irvine, have created a strain of mosquitoes capable of rapidly introducing malaria-blocking genes into a mosquito population through its progeny, ultimately eliminating the insects' ability to transmit the disease to humans.
