This microscopic 3D-printed Star Trek Voyager can move on its own

Physicists from Leiden University have 3D-printed a miniature version of an Intrepid-class starship from Star Trek (via PC Gamer). The idea of a tiny starship is probably something you haven't considered outside of the plot of a Star Trek episode, but this microscopic model is actually part of a larger research experiment the physicists published in the scientific journal Soft Matter.

The five micrometer long ship looks like the USS Voyager and was microprinted by the physicists for their microswimmer research. Unlike the impulse engines and warp drive of its TV counterpart, this Voyager is propelled through liquid by chemical reactions between its platinum coating and the hydrogen peroxide solution the physicists placed it in. Their...

Twitter is warning users about misleading tweets from Philadelphia's polling locations, offering an early preview of how it will handle the rest of the night. The platform has already restricted a tweet from Trump's director of election day operations, Mike Roman, among others.

"Misinformation being spread online has driven more calls to the Election Task Force hotline than actual incidents at polling sites," complained the Philadelphia District Attorney's Office to New York Times reporter Nick Corasaniti.

Roman posted a video showing a woman in Philadelphia apparently returning multiple ballots to a dropbox and claimed Democrats were "trying to STEAL THE ELECTION in broad daylight." But Philadelphia DAO spokeswoman Jane Roh noted that...

The Pixel 5 automatically turns into a wireless charging pad when you plug in a USB-C cable

The Pixel 5 is one of several flagship phones to offer a reverse wireless charging feature, but Google's done something particularly clever with its implementation of the feature here: whenever you plug in a USB-C cable, your Pixel 5 will automatically turn on its reverse wireless charging feature, effectively turning it into a Qi charging pad, as spotted by 9to5Google.

Google is pretty smart about how it handles the automated feature: according to a support doc, Battery Share will only turn on for "a short period." If the phone detects another Qi-compatible device has been placed on top to charge, it'll work as usual, otherwise it'll automatically turn Battery Share off.

This doesn't mean that you can't use reverse wireless charging...

HBO Max is the streaming service for me

In the last year, the number of streaming platforms has really gotten out of hand. There's Hulu, Netflix, Amazon Prime, HBO Max, Disney Plus, Apple TV Plus, CBS All Access (soon to be Paramount Plus), and Peacock — and each of them has different pricing tiers. If you scored free trials for Disney Plus and Apple TV Plus, like I did, you probably got to sample a healthy selection of them. Those trials, however, are starting to wind down. Which means it's time to figure out what's worth keeping and what's worth ditching: with this many monthly bills, you should absolutely play favorites. I was surprised to learn mine was HBO Max.

HBO Max isn't particularly well-defined. (It's HBO… and more?) It has baffling holes in its catalog thanks to...

The US will abandon a worldwide climate agreement on November 4th

The US will formally leave the landmark Paris climate agreement on November 4th, turning its back on the rest of the world as it comes together to stop climate change. How quickly the US takes on the planetary crisis will hinge on the results of today's election.

The Paris Agreement entered into force nearly four years ago today, on November 4th, 2016, after being adopted by every nation on Earth. (There are still a handful of countries that have yet to formally ratify the agreement). Donald Trump moved to remove the US from the accord soon after taking office, but the process took four years. That process comes to an end tomorrow, as voters wait to find out who the next US president will be.

If it's Joe...

Soothe your election nerves by solving crossword puzzles together on Twitch

Posted: 03 Nov 2020 01:31 PM PST

crossword

Today is Election Day and I am definitely anxious. But I have felt a physical sense of relaxation while watching this Twitch stream of people in the chat solving New York Times crossword puzzles together.

The game is very cleverly done. The stream shows the crossword and the clues. Users type in responses to clues in the chat, and then the puzzle will select that clue and fill in the answer. For example, somebody typing "29d ark" essentially translates to "the answer to 29 down is 'ark,'" and the game can select that clue and type out the answer in the crossword itself. And the whole thing is backed by an extremely chill instrumental soundtrack.

Natural Cycles wants to create wearable birth control

Posted: 03 Nov 2020 01:22 PM PST

Natural Cycles

Natural Cycles, the first "digital birth control" to get sign-off from the Food and Drug Administration, is back. This time, it's asking the agency to authorize integration with wearable devices like the Oura Ring. The feature could make it easier for users to use the app properly, but it doesn't sidestep some of the existing issues with app-based birth control.

The Natural Cycles app uses daily temperature measurements and period cycle tracking to predict the days someone is least likely to get pregnant. It falls under the broad category of fertility awareness birth control methods, where people track when they'd be ovulating and use that information to figure out when they'd have the best chance of conceiving. It tends to be conflated...

Election hoax spreading through text messages in Michigan

A text message campaign is targeting people in Michigan with misinformation about "ballot sensor issues." The messages claim a "typographical error" is causing people who voted for Joe Biden to have their votes switched to President Trump, and people who voted for Trump to have their votes switched to Biden, according to The Washington Post. The hoax message claims to be coming from the FBI.

Michigan Attorney General Dana Nessel warned voters the text messages are fake. "Dearborn voters, text messages are reportedly being sent to trick you into thinking there are ballot sensor issues," she tweeted. "Do not fall for it, it's a trick!"

In Flint, robocalls have been trying to trick people into voting tomorrow (which is not allowed) due to...

How should social media handle the election?

Election Day is here, and in the next few days or weeks, we'll know who won — but for lots of people, tonight isn't just about choosing the next president. It's also a stress test for online platforms and a measure of how carefully they can handle information when the stakes are this high.

By now, we know what failure could look like. In one nightmare scenario, a candidate (likely Trump) could preemptively declare victory before the votes are counted. In another, a fast-spreading rumor could cause serious offline unrest — like a viral hoax or misleading video that encourages vigilante violence. Since election night might not end with a clear winner, sites could be dealing with these threats for days.

The biggest platforms have laid out a...
