Origami-inspired artificial muscles outperform human ones

A remarkably simple system produces rather dramatic results.

Our robots manage some pretty impressive feats—including back flips—through the whirring of motors and hydraulic pumps. But all of life manages to perform far more impressive feats using muscles. Muscles allow incredibly fine control of movement, along with violent bursts of exertion. As a result, there has been a steady stream of attempts to craft artificial muscles.

But a team of Harvard and MIT researchers use part of their new paper to catalog all the ways that these efforts fall a bit short: energy efficiencies below two percent, extremely high voltage requirements, or extremely slow contractions. So they decided to focus on a different approach: pressure-driven artificial muscles. They devised a system that mixes this pressure with an origami-inspired skeleton to (by some measures) outperform muscles.

Pump it up

The basic design of their muscles is ingeniously simple. They muscles are centered on a rigid yet foldable "skeleton," which could be made of plastic or metal. This ensures that as the muscle expands and contracts, it folds (or unfolds) in a specific pattern that directs the force. The skeleton is surrounded by a sealed, flexible material, typically some sort of polymer sheet—think putting the skeleton in a form-fitting plastic bag. This can be filled using either a liquid or gas.

Waymo asks an Uber top lawyer: “Does Uber pay money to extortionists?”

Judge: “You’re not coming to grips with counsel’s question.”

SAN FRANCISCO—Under intense questioning by Waymo, Uber’s deputy general counsel, Angela Padilla, testified Wednesday that former employee Richard Jacobs was trying to extort the company when he submitted an explosive legal demand letter alleging possible criminal behavior on the part of himself and his former colleagues.

Yet, somehow, Uber settled legal demands made on behalf of Jacobs, who worked at one of Uber's most secretive internal divisions and was paid a total of $4.5 million to end his legal claims.

Jacobs, who testified Tuesday in court, disclosed those specific amounts. In a strange twist, however, Jacobs also repudiated some of the specific allegations that were in the letter written by his then-lawyer, Clayton Halunen, on Jacobs’ behalf. Padilla told the court that this letter amounted to extortion.

Mirai, the Internet-of-things malware that turns cameras, routers, and other household devices into potent distributed denial-of-service platforms, may be lying low, but it's certainly not dead. Last week, researchers identified a new outbreak that infected almost 100,000 devices in a matter of days.

In September of last year, Mirai emerged as a force to be reckoned with when it played a key role in silencing one of the most intrepid sources of security news in record-setting DDoS attacks topping 620 gigabits per second. Within a few weeks, Mirai's developer published the source code, a feat that allowed relatively unsophisticated people to wage the same types of extraordinarily big assaults. The release almost immediately helped touch off a series of large-scale attacks. The most serious one degraded or completely took down Twitter, GitHub, the PlayStation network, and hundreds of other sites by targeting Dyn, a service that provided domain name services to the affected sites.

Last week, researchers from China-based Netlab 360 say they spotted a new, publicly available Mirai variant. The changes allowed the malware to spread to networking devices made by ZyXEL Communications that could be remotely accessed over telnet using default passwords. One of the exploits was published on October 31. Over a span of 60 hours starting on November 22, the new Mirai strain was able to commandeer almost 100,000 devices. Virtually all of the infected devices used IP addresses local to Argentina, a possible indication the outbreak targeted customers of a regional service provider who were assigned unsecured modems.

EA on cosmetic game items: “You probably don’t want Darth Vader in pink”

LucasArts concerns about “violating canon” guided Battlefront 2‘s microtransactions

Earlier this month community furor over perceived "pay-to-win" elements in Star Wars: Battlefront 2 led EA to temporarily pull microtransactions from the game entirely. But those community complaints wouldn't apply to the kind of cosmetic mictrotransactions seen in many other online multiplayer games, which offer new costumes or visual flair without directly affecting gameplay.

EA CFO Blake Jorgensen says those kinds of offerings probably aren't in the cards for Battlefront 2, though, because of EA and LucasArts' focus on "not violating the canon of Star Wars."

In a presentation at the Credit Suisse Technology, Media, and Telecom Conference yesterday, Jorgensen said that "cosmetic things" in Battlefront 2 are difficult to pull off without messing up a brand "that has been built over many, many years.... Darth Vader in white probably doesn't make sense compared to Darth Vader in black. Not to mention you probably don't want Darth Vader in pink—no offense to pink, but I don't think that's right in the canon."

AT&T says it should be allowed to buy Time Warner because Comcast bought NBC

AT&T will use customer data to boost advertising business, court filing says.

AT&T is fighting back against the Trump administration's attempt to block its proposed purchase of Time Warner Inc. One week after the Department of Justice (DOJ) sued to block the deal, AT&T filed its first answer to the lawsuit yesterday.

AT&T denies the DOJ's allegations that a combined AT&T and Time Warner would raise prices on consumers, attempt to impede competition from online video distributors, and raise prices on rivals that pay for access to Time Warner programming.

Instead, AT&T says that the merger will benefit consumers without harming rivals. The merger "presents absolutely no risk of harm to competition or consumers," AT&T wrote. The DOJ has also failed to establish that AT&T and Time Warner "exercise market power with respect to any relevant market," the filing said. AT&T is just one of many video distributors these days because of the rapid growth of online video services, AT&T said.

EU Court: Cloud-Based TV Recorder Requires Rightsholder Permission

VCAST advertises itself as a VCR for the cloud, allowing users to record terrestrial TV into online storage to watch at a later point. But is it legal? According to a new ruling from the European Court of Justice, making TV shows available to consumers in this fashion must be authorized by rights holders.

Over the years, many useful devices have come along which enable the public to make copies of copyright works, the VCR (video cassette recorder) being a prime example.

But while many such devices have been consumed by history, their modern equivalents still pose tricky questions for copyright law. One such service is VCAST, which markets itself as a Video Cloud Recorder. It functions in a notionally similar way to its older cousin but substitutes cassette storage for that in the cloud.

VCAST targets the Italian market, allowing users to sign up in order to gain access to more than 50 digital terrestrial TV channels. However, rather than simply watching live, the user can tell VCAST to receive TV shows (via its own antenna system) while recording them to private cloud storage (such as Google Drive) for subsequent viewing over the Internet.

VCAST attracted the negative interests of rightsholders, including Mediaset-owned RTI, who doubted the legality of the service. So, in response, VCAST sued RTI at the Turin Court of First Instance, seeking a judgment confirming the legality of its operations. The company believed that since the recordings are placed in users’ own cloud storage, the Italian private copying exception would apply and rightsholders would be compensated.

Perhaps unsurprisingly given the complexity of the case, the Turin Court decided to refer questions to the European Court of Justice. It essentially asked whether the private copying exception is applicable when the copying requires a service like VCAST and whether such a service is allowed to operate without permission from copyright holders.

In September, Advocate General Szpunar published his opinion, concluding that EU law prohibits this kind of service when copyright holders haven’t given their permission. Today, the ECJ handed down its decision, broadly agreeing with Szpunar’s conclusion.

“By today’s judgment, the Court finds that the service provided by VCAST has a dual functionality, consisting in ensuring both the reproduction and the making available of protected works. To the extent that the service offered by VCAST consists in the making available of protected works, it falls within communication to the public,” the ECJ announced.

“In that regard, the Court recalls that, according to the directive, any communication to the public, including the making available of a protected work or subject-matter, requires the rightholder’s consent, given that the right of communication of works to the public should be understood, in a broad sense, as covering any transmission or retransmission of a work to the public by wire or wireless means, including broadcasting.”

The ECJ notes that the original transmission made by RTI was intended for one audience. In turn, the transmission by VCAST was intended for another. In this respect, the subsequent VCAST transmission was made to a “new public”, which means that copyright holder permission is required under EU law.

“Accordingly, such a remote recording service cannot fall within the private copying exception,” the ECJ concludes.

The full text of the judgment can be found here.

The key ruling reads as follows:

Directive 2001/29/EC of the European Parliament and of the Council of 22 May 2001 on the harmonisation of certain aspects of copyright and related rights in the information society, in particular Article 5(2)(b) thereof, must be interpreted as precluding national legislation which permits a commercial undertaking to provide private individuals with a cloud service for the remote recording of private copies of works protected by copyright, by means of a computer system, by actively involving itself in the recording, without the rightholder’s consent.
