Scientists have engineered a bacteria with a genetic ‘kill switch’
“This device will self-destruct in 10 seconds: 10…9…8…7…” How many times have you seen that in an action or sci-fi thriller? Can you imagine that scenario involving bacteria?

A new study identifies a promising technique to reverse male infertility. And it involves mice
Infertility in men can be an emotionally-difficult problem — and one that has been largely untreatable. But a new therapy being tested in mice is showing promising results. Plus, cell phone recordings tell of the final moments for South Korean teenagers caught in the ferry disaster. And a German exchange student is killed in America. All that and more in today’s Global Scan.

Brazilians welcome genetically-modified mosquito to help fight dengue fever
Dengue Fever is one of the biggest killers in tropical countries. It’s carried by mosquitoes that have proven tough to eradicate, so now officials in Brazil are trying a new approach: mosquitoes that have been genetically modified.Dengue Fever is one of the biggest killers in tropical countries.
