The Genetically Engineered Malaria-Proof Mosquito

GM Mosquito 543
The scientists tagged the gene with a fluorescent marker to ensure it had been inserted.
Scientists in the US have succeeded in genetically engineering a malaria-resistant mosquito.

The researchers, from the University of Arizona, introduced a gene that affected the insect’s gut, meaning the malaria parasite could not develop.

They report the advance, which also reduced the insects’ lifespan, in the journal PLoS Pathogens.

They say that the ultimate goal is to introduce malaria-resistant mosquitoes into the environment…

On the Path to Creating Designer Babies

On the Path to Creating Designer Babies 

This weeks special on designer babies includes the no-cry feature,
along with the pick-up-after-yourself gene, and extra tan skin

News that scientists have for the first time genetically altered a human embryo is drawing fire from some watchdog groups that say it’s a step toward creating “designer babies”. But an author of the study says the work was focused on stem cells. He notes that the researchers used an abnormal embryo that could never have developed into a baby anyway.

“None of us wants to make designer babies,” said Zev Rosenwaks, director of Center for Reproductive Medicine and Infertility at NewYork-Presbyterian/Weill Cornell Medical Center.

A Glowing Protein Shows How We Make Memories

A Glowing Protein Shows How We Make Memories

A new strain of genetically engineered mice has allowed researchers to pinpoint, for the first time, the precise cellular connections that form as a memory is created. By tracing a protein tagged to glow fluorescent green as it migrates through individual neurons, from the cell body out through the branching dendrites, the researchers could see exactly which synapses–connections to other neurons–were involved when the mice learned to fear an electric shock.
