The world is on track to add 700 million new ACs by 2030, and 1.6 billion by 2050, largely in hot, developing countries like India and Indonesia ... Air conditioners use refrigerants, and some of the most common types — hydrofluorocarbons, or HFCs — are powerful greenhouse gases, with thousands of times the warming potential of carbon dioxide. If HFC use continues to grow at its current pace, these chemicals could make up as much as 19 percent of emissions by 2050.

for decades scientists have been trying to develop an artificial womb that would re-create a more natural environment for a premature baby to continue to develop in. One of the main challenges was re-creating the intricate circulatory system that connects mom to fetus: the mom’s blood flows to the baby and back, exchanging oxygen for carbon dioxide. The blood needs to flow with just enough pressure, but an external pump can damage the baby’s heart.

The world of digital media is transforming so rapidly, it’s very hard for researchers to keep up with the effects on children ... TV today is, fundamentally, the same as TV 40 years ago, but the way we engage with computers today is very different from 20, even 10 years ago ... Screens are purely a delivery mechanism. What parents should be focused on is the content ... What matters...is the difference between passive and active consumption.

Uber’s penchant for secrecy can put it at odds with conventions of government transparency ... the company has convinced regulators to allow it to hide its ridership data — Uber’s agreement with Boston requires the city to keep Uber’s ridership data under wraps, even stipulating that the company will pay the city’s litigation costs in a fight to keep that data confidential. In San Francisco, data that Lyft or Uber gives the city is under seal and...hidden — even from city transportation planners

Lawmakers in Europe and the US have called on tech companies to more proactively police terrorist propaganda over the past year, following a spate of high-profile attacks ... a nonprofit organization has developed an algorithm that it says can automate the removal of terrorist-related content ... Digital rights groups have long expressed concerns over allowing Facebook and Twitter to be arbiters of free speech, and they fear that an automated system would lead to more widespread censorship.

The US has no federal law requiring e-waste be recycled. Currently, only 25 states in the US have laws establishing a funding system for the collection and recycling of electronic products, as well as bans against sending electronics to landfills. In the other 25 states, tossing toxic e-waste into the trash is perfectly legal. And then there’s the disastrous effect that e-waste has had on Third World countries.

Stingrays have turned up everywhere. They’ve been documented at 53 agencies spread across 21 states, used in major cities like New York and Chicago as well as smaller departments in Memphis, Durham, and San Jose. In a 2015 review, Baltimore police admitted using the device more than 4,300 times, sometimes for crimes as minor as a stolen cell phone. The US Marshals have even lent the devices out to Mexican officials hunting down cartels.

Replacing top-down management with distributed feedback is a very effective way of organizing a huge number of dispersed and untrained workers into an orderly and flexible network. But in traditional organizations, in addition to supervising workers, managers can also insulate them from irate customers. At the very least, managers have some legal restrictions on what they can fire for. Replacing them with customer judgments and automated systems puts workers in a precarious position.
