When it comes to making efficient fuel cells, it's all about the catalyst. A good catalyst will result in faster, more efficient chemical reactions and, thus, increased energy output. Today's fuel cells typically rely on platinum-based catalysts. But scientists at American University believe that spinach—considered a "superfood" because it is so packed with nutrients—would make an excellent renewable carbon-rich catalyst, based on their proof-of-principle experiments described in a recent paper published in the journal ACS Omega. Popeye would definitely approve.

The notion of exploiting the photosynthetic properties of spinach has been around for about 40 years now. Spinach is plentiful, cheap, easy to grow, and rich in iron and nitrogen. Many (many!) years ago, as a budding young science writer, I attended a conference talk by physicist Elias Greenbaum (then with Oak Ridge National Labs) about his spinach-related research. Specifically, he was interested in the protein-based "reaction centers" in spinach leaves that are the basic mechanism for photosynthesis—the chemical process by which plants convert carbon dioxide into oxygen and carbohydrates.

There are two types of reaction centers. One type, known as photosystem 1 (PS1), converts carbon dioxide into sugar; the other, photosystem 2 (PS2), splits water to produce oxygen. Most of the scientific interest is in PS1, which acts like a tiny photosensitive battery, absorbing energy from sunlight and emitting electrons with nearly 100-percent efficiency. In essence, energy from sunlight converts water into an oxygen molecule, a positively charged hydrogen ion, and a free electron. These three molecules then combine to form a sugar molecule. PS1s are capable of generating a light-induced flow of electricity in fractions of a second.

PlayStation 5 UI revealed: “Activity” shortcuts, picture-in-picture

Déjà vu for Xbox’s long-deceased “Snap” feature. Will media apps benefit?

Sony's drip-feed of PlayStation 5 information continued on Thursday with a surprise reveal of the upcoming console's "Control Center" interface. Sony has typically been bullish on updating its system menus between console generations, and the PlayStation 5 is clearly no exception.

The biggest feature revealed in this week's video is "Activities," a system-level companion to most consoles' "trophy" or "achievement" lists. In the case of PS5, when you're playing a supported game, you can tap into the Control Center to see levels, quests, or objectives that are available in your game (content you've already reached or unlocked, not spoilers). The idea is that you might have blown through a platforming level from start to finish but missed hidden items and collectibles needed to unlock a PS5 trophy.

Tap one of these Activity cards, and you'll quick-load into the relevant part of the game (thus flexing the PS5's NVMe 4.0 loading-time boosts) then be presented with a series of hints for any objectives or collectibles you've missed. At this point, if you're a paying PlayStation Plus subscriber, you can tap these hints to see pictures or video to guide your way instead of grabbing a nearby phone or laptop to search for a user-made tutorial. Then tap an additional button to leave these hints open in picture-in-picture mode.

Cloudflare Ordered to Block Pirate Music Site Following Universal Music Lawsuit

A Higher Regional Court in Germany has confirmed an injunction handed down against Cloudflare that prevents the CDN provider from facilitating access to pirate music site DDL-Music. The music industry welcomed the development, stating that a service that helps infringers evade prosecution through anonymization also acts illegally.

From: TF, for the latest news on copyright battles, piracy and more.

cloudflareCDN company Cloudflare has grown to become one of the most useful and important companies on the Internet, serving millions of websites that in turn serve countless millions of users of their own.

One of Cloudflare’s key aims is to be viewed as a neutral intermediary but that status is being chipped away by elements of the entertainment industries. The problem is that some of Cloudflare’s customers are pirate sites but as a service provider, Cloudflare insists that passing on complaints should be enough.

The music and movie industries, on the other hand, would like Cloudflare to either stop doing business with ‘bad players’ or take more responsibility for their actions.

Cloudflare Won’t Compromise So Legal Action Followed

Cloudflare is tied up in several lawsuits around the world, not for its own actions per se, but for the actions of some of its customers. In Germany there has just been a very interesting development, one that could have far-reaching consequences for how Cloudflare does business there.

Back in February, Germany-based visitors to pirate music site and Cloudflare customer DDL-Music.to were served with a rare ‘Error 451’ by Cloudflare, meaning that the site had been made inaccessible for legal reasons. At the time, no other information had been made public but as the days passed, a clearer picture emerged.

Complaint Filed By Universal Music GmbH

Early June 2019, Universal Music GmbH (Germany) sent a copyright infringement complaint to Cloudflare after finding links on DDL-Music to tracks by German singer Sarah Connor. The files themselves were not hosted by DDL-Music but could be found on a third-party hosting site. Universal asked Cloudflare make the tracks inaccessible within 24 hours but Cloudflare didn’t immediately comply.

In a subsequent response to Universal, Cloudflare denied being responsible for the activities of DDL-Music. It suggested that the label should confront DDL-Music directly, handing over an email address and details of the site’s hosting provider for contact purposes.

What happened in the interim isn’t clear but in December 2019 a hearing took place at the Cologne District Court, during which the court found that Cloudflare could be held liable for the copyright infringements of DDL-Music, if the CDN company failed to take action.

On January 30, 2020, the Cologne District Court went on to hand down a preliminary injunction against Cloudflare, advising that should it continue to facilitate access to the Universal content in question, it could be ordered to pay a fine of up to 250,000 euros ($270,000) or, in the alternative, the managing director of Cloudflare could serve up to six months in prison.

Preliminary Injunction Made Permanent

According to a statement issued late Thursday by German music industry group BVMI, the Cologne Higher Regional Court has now confirmed the judgment of the Cologne District Court. This means that Cloudflare must block access to the pirated music being offered on the website of DDL-Music. While Cloudflare will not be able to comply with that specific order (DDL-Music moved on a while ago) the principle stands. In Germany at least, Cloudflare can be held liable for the infringements of its users.

“Cloudflare offers a so-called CDN (Content Delivery Network), which is misused by structurally copyright-infringing websites in order to evade legal prosecution through anonymization. The Cologne Higher Regional Court has now put a stop to this: It has obliged Cloudflare to block customer content that has been reported to it by rights holders, or otherwise block the customer’s entire website,” BVMI’s statement reads.

Decision Welcomed By the Music Industry as a Tool to Fight Piracy

According to BVMI, the decision of the court is particularly noteworthy since it’s the first time that a higher regional court has confirmed an injunction against “an anonymization service” that conceals the identities of the servers operated by pirate sites. This decision will make that more difficult in future, the group says.

“The decision of the Cologne Higher Regional Court strengthens the position of rights holders in an important field and is a clear signal: A service that helps others to evade legal prosecution through anonymization is also illegal,” comments BVMI CEO, Dr. Florian Drücke.

“The decision is a further success for our industry against offers on the Internet that cause considerable damage to creatives and their partners and whose business models are based on generating considerable income with third-party content without acquiring licenses for this content.”

René Houareau, Managing Director of Law & Politics at the BVMI says the importance of the decision cannot be underestimated.

“Little by little we are getting closer to the modern understanding of the responsibility of all players on the Internet – especially through ambitious court decisions like this one,” Houareau says.

“An anonymization service may not allow third-parties to distribute illegal offers while disguising the identity of the servers of structurally infringing websites. In other words, excuses no longer apply in such cases. The services have to recognize more and more that some smoke screens no longer work.”

The developments in Germany arrive on the heels of a similar court ruling in Italy, which also went against Cloudflare. Following a complaint from TV platform Sky Italy and Italy’s top football league Serie A, Cloudflare is now required to block the domain names and IP-addresses of a pirate IPTV service. In that matter, Cloudflare argued that it merely passes on traffic, but the court wasn’t convinced.
