We reported a few weeks ago on a popular pirate site for science journals whose oversees admin was being sued by one of the world's leading academic publishers, Elsevier. Elsevier is the same New York publisher that the late Aaron Swartz had noted in his "Guerilla Open Access Manifesto" that told academics and researchers they had a "duty" to free the knowledge they were privileged to read behind Elsevier's paywall.

Because of the lawsuit, which Sci-Hub founder Alexandra Elbakyan has refused to participate in, she's been engaged in a game of domain-name Whac-A-Mole in response to Elsevier winning court orders demanding the shuttering of the popular site's domain name. The site allows anybody, not just academics, to access tens of millions of scholastic research articles for free.

When Ars interviewed Elbakyan and learned that she had a similar philosophy to Swartz, she had already altered the site's domain from sci-hub.org to sci-hub.io and changed others because of a court order blocking the .org domain. Now that domain, registered with Chinese registrar Now.cn, has also been killed. That has forced the site to move to sci-hub.bz and sci-hub.cc. This cat-and-mouse domain game is reminiscent of the decade-long game the admins of The Pirate Bay have been playing. When one domain gets lost to a court order, the site springs up on another.

Researchers are gaining ground in the struggle to understand the mysterious objects known as UltraLuminous X-ray sources (ULXs). These objects, named for their extreme brightness at X-ray wavelengths, are thought to be dense, compact objects like black holes or neutron stars. Their luminosity (which extends to other wavelengths) arises as they actively draw matter from an orbiting companion.

“We think these ‘ultra-luminous X-ray sources’ are somewhat special binary systems, sucking up gas at a much higher rate than an ordinary X-ray binary,” said Ciro Pinto from the Institute of Astronomy in Cambridge, UK, an author of a recent study. “Some host highly magnetised neutron stars, while others might conceal the long-sought-after intermediate-mass black holes, which have masses around 1000 times the mass of the Sun. But in the majority of cases, the reason for their extreme behaviour is still unclear.”

It’s been difficult to study them in detail because we've lacked the sensitivity needed to identify the emission lines and/or absorption lines created by specific elements. When light passes through material such as gas, certain wavelengths are absorbed by elements in the gas, leaving a blank line in the light source’s spectrum. Emission lines are light emitted by the element itself.

AUSTIN, Texas—Following a string of rumours, teasers, and enterprise exposé, chip-maker Nvidia will unveil consumer graphics cards based on its new Pascal architecture during a live event in Austin on Friday, May 6.

While Nvidia remains tight-lipped about what exactly will be shown—most rumours point towards two graphics cards, the GTX 1080 and 1070—those with quiet weekend plans can tune into the event livestream above at 8pm CDT (6pm PDT, 9pm EDT, or 2am BST on Saturday morning).

For the uninitiated, Pascal is Nvidia's latest and greatest graphics architecture, which promises to be both faster and more power efficient than the previous-generation Maxwell architecture. Exact details on the consumer chips won't appear until Friday, but the P100 enterprise card Nvidia unveiled in April does shed some light on what consumer Pascal might look like.

For as many plaudits as Tesla has received for its cars, plenty of its success must lie with that network of Superchargers. The far-sighted idea to build out the recharging infrastructure necessary to make road trips possible in an electric vehicle has surely done much to win friends, particularly among those vocal drivers for whom the inability of a car to drive across several of the smaller states in a day is an instant disqualification.

Outside of Tesla's walled garden, things can be a lot more confusing. There are different kinds of plugs. Some charging stations take all day to top up your battery; others can do it in a handful of hours. Maybe you get to the right charger, but an inconsiderate jerk in a gasoline-powered car is parked in the spot. These are all annoyances in the lives of EV early adopters and things that we'll need to change before those dreams of an all-EV passenger fleet are realized.

Chargepoint is one of the companies that wants to get us there, and on Wednesday it raised another $50 million to help it do so. As most EV drivers will know, Chargepoint's network is pretty extensive, with more than 28,000 charging points here in the US. Unlike other charging networks like NRG EVgo, it doesn't actually own the hardware; think of it more like Uber or AirBnB.

A California legislative committee will hold hearings on problems former Verizon customers are having more than a month after their service was switched to Frontier Communications.

Frontier purchased Verizon's FiOS and DSL businesses in California, Florida, and Texas, taking over the fiber and copper networks on April 1. Outages and various other service problems hit customers almost immediately, and Frontier still hasn't solved all the problems.

Mike Gatto, a Democratic legislator from Los Angeles who is chairman of the California State Assembly's Utilities & Commerce Committee, issued a statement yesterday about the "ongoing Frontier Communications telephone and Internet outages after the Verizon FiOS changeover."

For the past five years, a vulnerability in many Android phones has left users' text messages, call histories, and possibly other sensitive data open to snooping, security researchers said Thursday.

The flaw, which is most severe in Android versions 4.3 and earlier, allows low-privileged apps to access sensitive data that's supposed to be off-limits, according to a blog post published by security firm FireEye. But instead, the data is available by invoking permissions that are already requested by millions of apps available in Google Play. Company researchers said the vulnerability can also be exploited by adversaries who gain physical access to an unlocked handset. Indexed as CVE-2016-2060, the bug was first introduced when mobile chipmaker Qualcomm released a set of programming interfaces for a system service known as the "network_manager" and later the "netd" daemon.

"CVE-2016-2060 has been present on devices since at least 2011 and likely affects hundreds of Android models around the world," FireEye researchers wrote. "This vulnerability allows a seemingly benign application to access sensitive user data including SMS and call history and the ability to perform potentially sensitive actions such as changing system settings or disabling the lock screen. Devices running Android 4.3 (“Jelly Bean MR2”) or older are the most affected by the vulnerability, and are likely to remain unpatched. Newer devices utilizing SEAndroid are still affected, but to a lesser extent."

Step aside, Ben Carson. The once lauded ability to perform delicate operations with gifted hands may soon be replaced with the consistent precision of an autonomous robot. And—bonus—robots don’t get sleepy.

In a world’s first, researchers report using an autonomous robot to perform surgical operations on soft tissue and in living pigs, where the adroit droid stitched up broken bowels. The researchers published the robotic reveal in the journal Science Translational Medicine, and they noted the new machinery surpassed the consistency and precision of expert surgeons, laparoscopy, and robot-assisted (non-autonomous robotic) surgery.

The authors, led by Peter Kim at Children’s National Health System in Washington, DC, emphasized this feat is not intended to be a step toward completely replacing surgeons. Rather, they want the technology to provide new tools that help every operation go smoothly. “By having a tool like this and by making the procedures more intelligent, we can ensure better outcomes for patients,” Kim said.
