Lyft may be getting into the electric scooter game

The pay-per-use scooters aren't yet regulated in the city, which has caused some grumbling among residents over the last few months. Unlike with most bike-sharing systems, you don't need to deposit scooters in a dock; you can leave them anywhere, leading to careless riders dumping them on sidewalks and causing obstructions. Many riders are also zooming around without helmets, and some are using the scooters on sidewalks too.

San Francisco is clamping down on the menace though. Companies that want to run a service will soon need a permit and abide by some conditions: they'll need to prove they're reminding users to wear helmets and travel on the roads, and teaching riders how to park the scooters without littering sidewalks. Transit officials will grant up to five one-year permits -- companies can have 1,250 scooters in total on San Francisco's streets, and up to 2,500 in the back half of the trial program. The city is opening the application process this week.

A consultant for Lyft reportedly spoke with officials about a permit application, while the company has been prototyping scooter designs. Still, the company's interest seems to be in its early stages. Lyft could miss out on the city's pilot program and have to play catch up, or it might dodge a bullet (at least in SF), should officials decide against extending the pilot program, leaving operators with hundreds of scooters to ship to their services in other cities.

Lyft might not be the only major ridesharing company with skin in the game, though. Uber-owned bikesharing service Jump is considering a push into scooters as well.

NASA will create coldest place in the universe to study quantum physics

The box creates a temperature roughly 10 billion times colder than the vacuum of space, and then uses a combination of lasers and electromagnetism to slow atoms until they're virtually stationary. At that point, quantum mechanics override conventional physics and make the atoms behave more like waves than particles. In the very low gravity environment of the ISS, those atoms should hold their wave-like state for roughly five to 10 seconds -- still a brief window, but much easier to study.

The extra analysis time could lead to a greater understanding of quantum physics, which in turn could be applied to quantum computing. It may also help us detect dark energy, the most common substance in the universe. While you may not see results for a long time, the lab's impact might be felt for a long, long time to come.

China’s Netflix equivalent just opened its first cinema

According to the South China Morning Post, iQiyi plans to open more of these theaters, branded "Yuke," in more Chinese cities. This initial theater opened in Zhongshan city in the southern Guangdong province, and will allow people there book private, on-demand showings of iQiyi's online content. Such a deal isn't too far-fetched, either. It mirrors a rumored Netflix purchase of theater companies like Landmark, showing that online companies continue to want to make inroads to our offline lives.

Oculus’ privacy center now shows you what data is being collected

That's also where users can download their data and delete their Oculus account, if they so choose (though that won't wipe away certain info like purchase agreements, which the company holds on to for tax purposes). Information that's been anonymized, like the VR controller gestures, aren't shown in the Privacy Center, and neither is locally-stored data. It's essentially the platform's effort to clear a path between users and their data, an effort toward transparency that stands in contrast to parent company Facebook's ongoing blunders over individual privacy.

Official ‘Fortnite’ tournaments will offer $100 million in prizes

The official Fortnite competitive scene will kick off this year. Details on how pro play will work are forthcoming, though Epic said in its announcement it is seeking a different approach to eSports: "We plan to be more inclusive, and focused on the joy of playing and watching the game."

It's possible that professional play will follow a similar system to last weekend's Solo Showdown mode, where players picked up points depending on how highly they placed in 50 games, rather than having to win matches outright. There's a certain amount of luck involved in battle royale games like Fortnite and PlayerUnknown's Battlegrounds, as the weapons and items you collect spawn at random and you might find yourself far away from the active play area as a barrier forces players closer together. Epic will have to mitigate the luck factor as much as possible to ensure player skill is the most important aspect of competitive play.

The prize pool investment far surpasses that of the Overwatch League, Blizzard's most serious effort in making Overwatch a leading eSport. The league is offering $3.5 million in total in its first year; the winning team in each of the four stages claims $100,000, with the overall champion taking away $1 million. Epic's cash injection also eclipses other major eSports, as The Verge pointed out. Dota 2 prizes have totaled more than $140 million over the last five years, and winners in the Counter-Strike: Global Offensive and League of Legends scenes have claimed a little over $50 million in each game.

We've seen scant few major Fortnite eSports events so far, but those that have bubbled up have been successful, which is hardly surprising given the game's immense popularity. Last month, a tournament held by Fortnite's most famous streamer Ninja in Las Vegas claimed more than 600,000 concurrent viewers on Twitch, beating out his own record from the first time he played with Drake.

At the E3 convention next month, there's an official, quasi-pro-am tournament that will pair up celebrities with skilled streamers. It's not clear who, exactly, will be playing, but the celebrity involvement could raise the game's profile even further, and the tournament's format could provide further hints on what lies ahead for Fortnite's pro scene.

Tesla and Consumer Reports continue feud following Model 3 review

Not surprisingly, Tesla took issue with the claim. In a statement, a spokesperson maintained that its testing showed a 133-foot braking distance using the 18-inch Michelin all-season tires. The company also claimed that CR's test units may have been affected by a number of factors, including temperatures (both for the tires and the environment), the road surface and even "past driving behavior." And if there were issues, the spokesperson said, Tesla was in a better place to "address more corner cases" through software updates that could improve the stopping distance.

Who's telling the truth? It's not entirely clear. CR noted that other outlets' braking results were all over the map. Car and Driver said it saw a "bizarre amount of variation" in its more aggressive 70-to-0MPH tests, with an average of 176 feet but an "interminable" 196 feet in one case. This wasn't always the case -- Motor Trend saw the car come to a halt from 60MPH in just 119 feet with 19-inch wheels.

As it stands, braking wasn't CR's only objection. It complained about "stiff" ride quality, and was worried that the near-exclusive use of a touchscreen for the interface risked causing a "distraction" for drivers who had to take their eyes off the road to make changes. The publication had plenty of positive compliments for the Model 3, including its "record" EV range (350 miles with heavy regenerative braking) and "agile" performance that made it more exciting to drive than some sports cars. Even so, it's clear that Elon Musk and crew won't warm up to CR unless there's either a change of heart (not very likely) or an update that tackles the braking issue.

Google Maps can replace the dull arrow with 3D car icons

Google doesn't just want to reserve Maps navigation icons for special occasions. If you're using iOS, you can now replace Google Maps' drab blue arrow with a 3D car. You can even choose a vehicle that more closely reflects what you're driving, whether it's a sedan, truck or SUV. Is it silly and purely cosmetic? You bet -- but it adds a bit of character to an app that (let's be honest) often feels a bit soulless. Here's hoping the selection widens over time to keep commutes lively.

Drug could prevent memory loss in deep space astronauts

Importantly, the effects are long-lasting. Untreated mice showed memory problems about three months after their exposure, but those who received the drug soon after exposure demonstrated healthy behavior. That's crucial when trips to Mars will include months of deep space flight and prolonged stays on a relatively unprotected planet.

The medicine might be useful sooner than you think. There are already similar compounds in use for cancer treatment trials, so it wouldn't take a huge leap to use this anti-radiation medicine in the real world. And it wouldn't just be useful for astronauts, either. It could help prevent cognitive issues after cancer radiation therapy, or alleviate the effects of diseases like Alzheimer's.

Intel details fourth Spectre-style CPU security flaw

Like earlier vulnerabilities, the new issue affects most modern chip architectures, including many of Intel's CPUs from the past few years.

The good news: many of the same patches for earlier Spectre and Meltdown variants should mitigate against Variant 4. There is the potential for new exploits, however, so Intel and partners (including PC makers and operating system vendors) are releasing BIOS and software fixes in the "coming weeks." The solution is turned off by default, though -- Intel estimates a roughly 2 to 8 percent performance hit in benchmarks, and it's clearly not eager to impose that penalty on users unless there's evidence of an exploit in the wild.

There won't be a permanent solution to Spectre-like exploits until Intel and its competitors release updated chips. As such, it won't be alarming if it turns out there are more disclosures like this. The industry hasn't really had such universal hardware-related flaws before, and it's not clear where they end.
