The Google family has a plan to remove mosquitoes around the world



(Bloomberg) – Silicon Valley researchers are attacking flying bloodshed in the Fresno County of California. It's the first salvo in the unlikely war for the parent company Google Alphabet Inc: eradicating mosquito-borne diseases around the world.

The white Mercedes top vanes over suburban large and strip mallets like a swarm of men Aedes aegypti mosquitoes shoot out of a black plastic tube on the passenger's window. These pests are small and have wingspan just a few millimeters, but they are invisible.

"Do you hear the little sound?" Says Kathleen Parkes, a spokesman for Verily Life Sciences, an alphabet unit. She left the van in the car, the windows down. "Like a duh-duh-duh? That's the release of mosquitoes."

Jacob Crawford, a faithful scientist with Parkes, is beginning to describe the technique of controlling mosquitoes with dazzling potential. These specific pus, he explains, were brought up in the ultra-high-tech environment of Verily's automated mosquito breeding system, located 200 miles south of San Francisco. They were infected with Wolbachia, a common bacterium. When the 80,000 laboratory strains infected with Wolbachia, male mosquitoes associate with their counterparts in the wild, are the result of a destructive destruction: the offspring never get out.

Better is 79,999. "One just hit the windscreen," says Crawford.

Removing a brain-induced illness is a serious factor for Alphabet, even though it is just one of many healthcare and life science outlets. Verified by Verily and other Alphabet affiliates, Intelligent Contact Lenses, Artificial Intelligence for Health Care, and Molecular Aging Mechanisms. This month, Google hired Geisinger CEO David Feinberg to oversee a number of healthcare initiatives.

He really watches his technology. However, it is clear that if he succeeds in controlling the mosquitoes easily and cheap enough, he could have a lucrative offer on his hands: Many governments and businesses around the world might be glad to pay for solving their mosquito problems.

In the dry climate of the Californian Central Valley, A. aegypti they are hated for their evil bite. But at least, they usually do not pass on diseases. Other places are not lucky. Types of mosquitoes are among the world's most dangerous, spreading diseases, such as dengue fever and chikungunya in tropical and subtropical areas. Diseases that the system carries kill tens of thousands of people every year and infect millions of other people. Releasing mosquitoes infected with Wolbachia into the wild can eventually destroy the entire population of deadly mosquitoes and the diseases they carry.

At least it is a plan if field tests appear in California. Every morning, during the mosquito season, which lasts from April to November, the van, on which Debug Fresno is located, passes through leafy residential streets full of multi-level homes. At predetermined locations, the algorithm automatically releases carefully calculated numbers of mosquitoes, counting each individual insect using a laser as it exits from the delivery.

Since efforts to mitigate mosquito-related illness have accelerated, several different approaches to the problem have emerged. Bill Gates himself promised more than $ 1 billion in technology that can help eliminate malaria, including controversial attempts to modify mosquito genetics. Verily's approach is based on a version of a very old strategy, known as a sterile insect technique, in which the population is gradually killed by a breach of reproductive capacity.

It is unclear what would happen if mosquitoes who caused disease in the world were deprived of it. The environmental role played by mosquitoes has not been thoroughly studied, although some scientists have suggested that we could be without them without them. But that is clear A. aegypti does not have a business in Fresno County. Native to warmer, wet climatic conditions, no one knows where they came from when they first appeared in 2013. Everything is certain they are spreading extremely fast.

"After we found out, we have made a huge and far-reaching effort to prevent comrades from setting up and eliminating it," says Jodi Holeman, director of scientific services for the Mosquito Abatement District in Fresno Province. "We did not succeed in any way, shape or shape."

The district was overwhelmed by the fact that it had no problem with mosquitoes to have the one who made the villagers avoid their yards and porches. Unlike most mosquitoes, A. aegypti live and breed in places inhabited by humans, their eggs, for example, a few droplets of standing water on the underside of a wineglass that remained on the balcony, then hiding under the bed and cupboards, biting his legs and ankles. This makes it much harder to fight. Going from door to door, he asks residents to drain standing water, that's not cut, so in 2016 Fresno joined a scientist named Stephen Dobson and his company MosquitoMate.

It was Dobson's lab that came up to how to infect mosquitoes in the form of Wolbachia, which differs from the type of bacteria that mosquitoes usually carry. That's what makes eggs harmless. MosquitoMate produces two species of mosquito-infected mosquitoes, A. aegypti and Aedes albopictus. Fresno has become one of his test sites.

The initial Fresno study was for the first time male A. aegypti infected by bacteria have sometimes been released in the US. The next year Verily stepped in to help expand these efforts and bring more advanced technology into the breeding and release process that they hoped eventually could fight mosquito-scale mosquitoes.

It seems to work. This year, Verily signed up for the second season. Two Verily cars consist of four different neighborhoods that hit more than 3,000 homes. For over six months, the company has released more than 15 million mosquitoes. The results of 2017 indicated that the population of biting female mosquitoes fell by two-thirds. This year, program improvements have reduced the mosquito population by an incredible 95 percent. Verily's second project at Innisfaile in Australia, which ended in June, reduced the mosquito population by 80 percent. This is good for ultimately bringing technology to other parts of the world – regions ravaged by not only upheaval ankles but deadly diseases.

Initially, Verily's leaders feared the community would resist the fight against mistakes with multiple errors. So the company set up an information office, complete with a cage filled with masculine mosquitoes, which people could hold their hands to find that the men were not thrown away. (Only female mosquitoes, which is why this and similar projects carefully release only men.)

"We really appreciate being here," said Clifford Lopes, a resident. "I boast about how I can now sit on my veranda and I do not feel it, either."

In videos from original studies, you can see Holeman, a scientist from Fresno County, who mosquitoes blow out a mosquito. The release van is now packed with proprietary technology, including software that determines exactly what areas of mosquitoes around you should be discharged, and a laser sensitive to count with each individual at its output, generates a number of data that can later be used for fine -tune process.

At Verily's headquarters, the mosquito 'factory' is even more automated. Once the eggs are laid, robots enter mosquitoes into adulthood, wrap them in containers filled with water and air, feed them and keep them warm. Still other robots sort them by gender, first by size (women are bigger) and then optically using proprietary technology. The chimeras receive a digital identifier that allows them to track them from egg status to specific GPS coordinates where they are released.

With this season, the company must still decide whether to extend the program next year. He really would not say how much it costs to manufacture and release tens of thousands of mosquitoes every day, but it's a sure bet that it's still a costly thing.

"A key part is the effort to make such a program affordable and effective," says Crawford, a scientific scientist, "to be able to go to places where there is not much money."
