If we start deliberately cooling the Earth, we may not be able to stop

Blasting aerosols into the sky to reverse climate change seems like an exciting proposition, but it may be too dangerous to attempt: If we try and then suddenly halt this form of geoengineering, it could cause more damage than climate change itself, according to new research.

Global warming is a pressing problem, and some scientists believe that sending a plane to spray sulfate aerosols into the sky will help cool down the Earth. In a study published today in the journal Nature Ecology & Evolution, researchers used models to predict what would happen if we sprayed the aerosols for 50 years, and then abruptly stopped. They found that this scenario would cause the Earth to warm up too quickly to give animals time to move to more…

Rupert Murdoch calls for Facebook and Google to subsidize the news business

Rupert Murdoch, the executive chairman of publishing empire News Corporation, issued a statement today proposing a new licensing deal between media organizations and platform-owning tech companies that would see entities like Facebook and Google pay fees to news outlets.

Citing the popularization of “scurrilous news sources through algorithms that are profitable for these platforms but inherently unreliable,” Murdoch says Facebook and Google should pay money in an arrangement similar to so-called carriage fees. These fees are the money paid by cable and satellite television providers to local, over-the-air broadcast stations for the right to carry local transmissions. In the US, this is an industry norm, with the fees being baked into…

Immortality isn’t all it’s cracked up to be in Altered Carbon’s violent cyberpunk future

Ever since HBO launched its widely successful fantasy drama Game of Thrones, other networks have been on the hunt for the next big genre show. Amazon has Man in the High Castle. Starz has American Gods. Syfy has The Expanse. These shows demonstrated that science fiction and fantasy could be a form of astute commentary on society embraced by mainstream audiences, instead of just escapism. While Netflix has fielded its own prestigious shows, like House of Cards and The Crown, it has lagged behind when it comes to science fiction. Its new sci-fi thriller Altered Carbon finally delivers the goods: a hard-hitting genre story that doesn’t shy away from complexity and ugly truths about humanity.

Altered Carbon is based on the 2002 novel by…

Patients turned away, SpaceX delays: here’s how the government shutdown hits science

As Congress scrambles to reach a budget deal, the federal government is still shut down. That means hundreds of thousands of federal employees will not be returning to work this week — including employees for the national agencies that deal with science, like the National Institutes of Health or the Environmental Protection Agency.

Since we don’t know how long the shutdown will last, it’s impossible to say how far-ranging its effects will be. But we can look to the agencies’ contingency plans and the aftermath of the 2013 federal shutdown, which lasted 16 days, for clues.

Here is what the government shutdown will mean for these science agencies:

National Institutes of Health (NIH)

Patients currently enrolled in NIH studies — for…

Thor: Ragnarok leaks onto the web a month early after huge Movies Anywhere mix-up

Thor: Ragnarok has quickly spread across torrent sites after customers were able to prematurely download the title an entire month before its planned mid-February digital release. The error is apparently the result of a miscommunication between Vudu and Apple.

Both companies participate in the Movies Anywhere program, which lets consumers watch their digital movie libraries across devices and various apps such as iTunes, Vudu, Amazon Video, Google Play Movies, and others. It’s a fantastic idea that basically bulldozes any kind of ecosystem lock-in — at least when it comes to movies.

According to TorrentFreak, some users on Reddit noticed that when placing a preorder for the well-received Thor: Ragnarok with Vudu, the movie showed up as…

The surrealist horror film Mandy pits Nicolas Cage against murderous hippies

Welcome to Cheat Sheet, our brief, breakdown-style reviews of festival films, VR previews, and other special event releases. This review comes from the 2018 Sundance Film Festival.

Director Panos Cosmatos once said that his 2010 debut film Beyond the Black Rainbow was “a sort of imagining of an old film that doesn’t exist,” inspired by a childhood obsession with the box art of horror movies he wasn’t allowed to watch. His new follow-up Mandy, which Cosmatos describes as a “companion piece” to Black Rainbow, feels like a pulpier and more self-aware exploration of the same premise — with a strong helping of Dungeons & Dragons and heavy metal.

Sometimes Mandy is a serious horror film. Sometimes it’s an over-the-top pastiche. Sometimes it’s…
