Premonition takes disease tracking to the next level

Five years after launching an experiment to see if advanced sensors and artificial intelligence could spot the signs of a disease outbreak before it happens, Microsoft says it’s ramping up Project Premonition to create an honest-to-goodness biothreat protection network.

The network will involve setting up about 100 sensor stations in Texas’ Harris County, to track swarms of mosquitoes that could transmit diseases ranging from malaria and dengue fever to Zika and West Nile viruses. AI algorithms will analyze that tracking data for the telltale signs of an epidemic in the making, just as weather forecasting programs look for the signs of a storm on the way.

“It will really be almost like a weather map, the likes of which has not really been seen before in the mosquito vector space,” Ethan Jackson, director of Microsoft Premonition, told me.

The expansion of the Premonition program was announced today in conjunction with this week’s annual Microsoft Ignite conference for software developers.

Bill Gates connects ‘Star Trek’ to fighting malaria

It’s Mosquito Week at the Bill & Melinda Gates Foundation, a time to focus on the global campaign to eradicate malaria and other mosquito-borne diseases. And if delving into the nuts and bolts of developing an effective malaria vaccine doesn’t grab you, how about adding a “Star Trek” angle?

That’s exactly what Microsoft co-founder Bill Gates is doing in today’s Gates Notes posting to kick off Mosquito Week.

Gates Foundation backs malaria-blocking mosquito

The Bill & Melinda Gates Foundation is extending its partnership with Oxitec, a British mosquito control company, to develop mosquitoes that are genetically engineered to suppress malaria.

Oxitec’s latest project follows up on its work with Aedes aegypti, the mosquito species that can spread a range of diseases including yellow fever, dengue fever, chikungunya and Zika fever — but not malaria. A different type of mosquito, Anopheles, is the carrier for malaria parasites.

Previously, the Gates Foundation supported Oxitec’s development of male Aedes mosquitoes that have been genetically engineered so that their female offspring don’t survive to adulthood.

How mosquitoes associate scents with swats

Does it do any good to swat at a mosquito if you miss? Yes, according to a newly published study.

A novel experiment conducted primarily by biologists at the University of Washington found that mosquitoes seem to associate the shock of the swat with the swatter’s scent, and learn to stay away.

“Once mosquitoes learned odors in an aversive manner, those odors caused aversive responses on the same order as responses to DEET, which is one of the most effective mosquito repellents,” senior author Jeff Riffell, a UW biology professor, said in a news release.

“Moreover, mosquitoes remember the trained odors for days,” he said.

How a robo-trap zeroes in on Zika mosquitoes

BOSTON – Microsoft’s robotic mosquito trap is so smart it can tell one insect species from another – and that’s good news for scientists fighting the Zika virus, dengue fever and other mosquito-borne maladies.

It can also tell if you’re buzzing an electric toothbrush in its vicinity.

The toothbrush was used to dramatic effect today by Ethan Jackson, a Microsoft researcher from Redmond, Wash.

Jackson heads up Project Premonition, a research effort aimed at giving epidemiologists smarter tools for tracking disease outbreaks. Today he showed how the high-tech trap works at the American Association for the Advancement of Science’s annual meeting in Boston.
