ABBA Is Going on Tour—As Holograms

Missed your chance to watch ABBA perform live at the peak of their popularity? You’re in luck: Fans will soon be able to see the group in concert in all their chart-topping, 1970s glory—or rather, they’ll be able to see their holograms. As Mashable reports, a virtual version of the Swedish pop band is getting ready to go on tour.

ABBA split up in 1982, and the band hasn't been on tour since. (Though they did get together for a surprise reunion performance in 2016.) All four members of ABBA are still alive, but apparently not up for reentering the concert circuit when they can earn money on a holographic tour from the comfort of their homes.

The musicians of ABBA have already had the necessary measurements taken to bring their digital selves to life. The final holograms will resemble the band in the late 1970s, with their images projected in front of physical performers. Part of the show will be played live, but the main vocals will be lifted from original ABBA records and recordings of their 1977 Australian tour.

ABBA won’t be the first musical act to perform via hologram. Tupac Shakur, Michael Jackson, and Dean Martin have all been revived using the technology, but this may be one of the first times computerized avatars are standing in for big-name performers who are still around. ABBA super-fans will find out if “SOS” still sounds as catchy from the mouths of holograms when the tour launches in 2019.

These LED Crosswalks Adapt to Whoever Is Crossing

Crosswalks are an often-neglected part of urban design; they’re usually just white stripes on dark asphalt. But recently, they’re getting more exciting—and safer—makeovers. In the Netherlands, there is a glow-in-the-dark crosswalk. In western India, there is a 3D crosswalk. And now, in London, there’s an interactive LED crosswalk that changes its configuration based on the situation, as Fast Company reports.

Created by the London-based design studio Umbrellium, the Starling Crossing (short for the much more tongue-twisting STigmergic Adaptive Responsive LearnING Crossing) changes its layout, size, configuration, and other design factors based on who’s waiting to cross and where they’re going.

“The Starling Crossing is a pedestrian crossing, built on today’s technology, that puts people first, enabling them to cross safely the way they want to cross, rather than one that tells them they can only cross in one place or a fixed way,” the company writes. That means that the system—which relies on cameras and artificial intelligence to monitor both pedestrian and vehicle traffic—adapts based on road conditions and where it thinks a pedestrian is going to go.

If a bike is coming down the street, for example, it will project a place for the cyclist to wait for the light in the crosswalk. If the person is veering left like they’re going to cross diagonally, it will move the light-up crosswalk that way. During rush hour, when there are more pedestrians trying to get across the street, it will widen to accommodate them. It can also detect wet or dark conditions, making the crosswalk path wider to give pedestrians more of a buffer zone. Though the neural network can calculate people’s trajectories and velocity, it can also trigger a pattern of warning lights to alert people that they’re about to walk right into an oncoming bike or other unexpected hazard.

All this is to say that the system adapts to the reality of the road and traffic patterns, rather than forcing pedestrians to stay within the confines of a crosswalk system that was designed for car traffic.

The prototype is currently installed on a TV studio set in London, not a real road, and it still has plenty of safety testing to go through before it will appear on a road near you. But hopefully this is the kind of road infrastructure we’ll soon be able to see out in the real world.

How to Make Sure Your Cell Phone Receives Emergency Alerts

Thanks to smartphones, we’re more plugged into the world than ever before. Some of us receive notifications for everything from Amber Alerts to trending news stories, so it makes sense that we’d also depend on our phones to alert us to emergencies in our neighborhoods. But as The Daily Dot reports, relying on your cell phone alone for such news might leave you in a dangerous situation.

Unlike Amber Alerts, local notifications for natural disasters like wildfires don’t operate on a broad alert system. If counties were to contact every single resident every time a specific area was threatened, it would lead to traffic jams and unnecessary panic, putting more lives at risk. So instead, the police only contact people in their database that live in the affected location.

The Reverse 911 law allows law enforcement to contact you at your home in case of emergencies. If you have a landline you can expect to get the call there, but because the law was enacted before the age of cell phones, receiving a call anywhere else isn’t guaranteed. To make sure your county knows to contact you on your cell phone, you need to reach out to them and ask for that number to be listed as your primary mode of contact. Just over half of all households in the country use cell phones for all personal phone communications, which means that most Americans need to opt in to receive life-saving emergency notifications.

Fortunately, getting your cell number into your county’s database isn’t hard. You can starting by searching your county’s name and “emergency alert” online. There’s no uniform system across the U.S., but on Los Angeles County’s emergency alert page, for example, residents are asked to indicate their name, address, phone number, and the type of alerts they wish to receive. This information can be updated at any time—so if you get a new phone number, make sure your local police department is one of the first to know.
