A few weeks ago, up to 40 people from the Yamal Peninsula in Siberia were hospitalized after a heatwave thawed permafrost, releasing a “zombie outbreak” of anthrax. Now, the Siberian Times reports that experts fear the thawing could spell the return of the eradicated smallpox virus.

During the 1800s, there were repeated outbreaks of smallpox in a small Siberian town, with hundreds of bodies buried near the banks of the Kolyma River. Some 120 years later, this summer’s heatwave has been melting the permafrost surrounding the town at a rate three times faster than usual. This has increased water levels in the river and is subsequently eroding away its banks where the bodies are buried.

While the risk at the moment is low, and with scientists aware of the issue for some time now, the current troubles of permafrost around the site and the Kolyma River are ringing alarms.

Starting later this month, Uber will allow customers in downtown Pittsburgh to summon self-driving cars from their phones, crossing an important milestone that no automotive or technology company has yet achieved. Google, widely regarded as the leader in the field, has been testing its fleet for several years, and Tesla Motors offers Autopilot, essentially a souped-up cruise control that drives the car on the highway. Earlier this week, Ford announced plans for an autonomous ride-sharing service. But none of these companies has yet brought a self-driving car-sharing service to market.

Uber’s Pittsburgh fleet, which will be supervised by humans in the driver’s seat for the time being, consists of specially modified Volvo XC90 sport-utility vehicles outfitted with dozens of sensors that use cameras, lasers, radar, and GPS receivers. Volvo Cars has so far delivered a handful of vehicles out of a total of 100 due by the end of the year. The two companies signed a pact earlier this year to spend $300 million to develop a fully autonomous car that will be ready for the road by 2021.

The Volvo deal isn’t exclusive; Uber plans to partner with other automakers as it races to recruit more engineers. In July the company reached an agreement to buy Otto, a 91-employee driverless truck startup that was founded earlier this year and includes engineers from a number of high-profile tech companies attempting to bring driverless cars to market, including Google, Apple, and Tesla. Uber declined to disclose the terms of the arrangement, but a person familiar with the deal says that if targets are met, it would be worth 1 percent of Uber’s most recent valuation. That would imply a price of about $680 million. Otto’s current employees will also collectively receive 20 percent of any profits Uber earns from building an autonomous trucking business.

How will we interact with the intelligent machines of the future? If you’re asking Bryan Johnson, founder of startup Kernel, he’ll tell you those machines should be implanted inside our brains.

His team is working with top neuroscientists to build a tiny brain chip—also known as a neuroprosthetic —to help people with disease-related brain damage. In the long term, though, Johnson sees the product applicable to anyone who wants a bit of a brain boost.

Yes, some might flag this technology as yet another invention leading us toward a future where technology just helps the privileged get further in life.

Cientistas descobrem um segredo para a longevidade nos Latinos ’, com a esperança de retardar o envelhecimento para todos.

A pesquisa também ajuda a responder a perguntas sobre por que algumas pessoas morrem jovens, enquanto outros vivem até a velhice, e que doenças crônicas têm a ver com o envelhecimento.

A team of Harvard Medical School scientists, which includes genetics professor George Church, have designed a bacterial genome that has been rewritten on a massive scale, with changes in more than 62,000 spots.

They haven’t used it to make living E. coli yet, but the findings, reported today in Science, mark progress towards genetically engineered bacteria that could make new materials without risk of exchanging genes with organisms in the wild.

“It‘s an important step forward for demonstrating the malleability of the genetic code and how entirely new types of biological functions and properties can be extracted from organisms through genomes that have been recoded,” Farren Isaacs of Yale University, who has worked with the team in the past, told Nature.
