Old Tevatron data turns up new four-quark particle

It’s a brand-new species—the first particle with four flavors of quarks.

The particles known as quarks were suggested as a way of making sense of a large collection of particles that kept popping out of our atom smashers. While some particles, like electrons and neutrinos, are fundamental, others are composed of two or three quarks and a few gluons to hold them together. The familiar proton and neutron, for example, are composed of collections of three quarks.

But as far as we knew, three has been the upper limit for quarks in a single particle, so that's all our theories bothered to deal with. Over the past several years, however, evidence has been piling up that four- and even five-quark particles can be produced in particle accelerators. That data has led to a little theoretical confusion, as it wasn't clear whether these were single particles with all those quarks or a composite object composed of a combination of two familiar particles.

Now, researchers who worked on Fermilab's Tevatron have gone through old data and discovered that it too had produced evidence of a four-quark particle. This is the first four-quark particle to have each of its component quarks come in different flavors. And the particle's mass suggests that it's likely to be a single unit rather than a composite particle.

Ruckus Wireless: OpenG soll das LTE-Abdeckungsproblem in Gebäuden lösen

Die Verwendung kleiner Mobilfunkzellen zur Verbesserung des Empfangs hat sich bisher nicht so recht durchgesetzt. Zu aufwändig ist es, lizenziertes Mobilfunkspektrum verteilen zu dürfen. Ruckus Wireless will das Problem mit dem 3,5-GHz-Band lösen. (Long Term Evolution, WLAN)

Wikimedia Foundation director resigns after uproar over “Knowledge Engine”

It’s damage-control time at the world’s biggest encyclopedia.

The head of the Wikimedia Foundation, the nonprofit that runs Wikipedia and related websites, has unexpectedly resigned. Lila Tretikov said Thursday in a statement that "with great respect," she has tendered her resignation as executive director of the Wikimedia Foundation. "The Board tasked me with making changes to serve the next generation and ensure our impact in the future," Tretikov wrote. "Driving these changes has been challenging, and I have always appreciated the open and honest discourse we have had along the way."

Tretikov's resignation comes at a time of unprecedented tension between the community of editors and the Board of Trustees that runs the Wikimedia Foundation. Last month, a newly appointed board member stepped down after hundreds of editors signed a "vote of no confidence."

Following that resignation, a second uproar arose over a $250,000 grant from the Knight Foundation to help Wikimedia Foundation create a "knowledge engine" that would improve search. Some activist Wikipedia editors had been asking to see documentation about the Knight Foundation grant for several months, but Wikimedia was not forthcoming with the details.

Pics of Porsches and Aston Martins leaked ahead of Geneva Auto Show

See what the 911R and DB11 will look like.

The Geneva Auto Show has just gotten underway in Europe, and we should have a full report on all the stars of the show later this week. But ahead of the show, images have leaked of two of its expected stars, Porsche's new 911R, and Aston Martin's DB11.

First up is the "new" Porsche, which is actually new version of an existing model. When the latest 911 GT3 debuted in 2014, it drew a bit of criticism from purists because it meant the loss of a manual gearbox. Even though racing Porsches have been semi-automatic for years, many driving enthusiasts want nothing to do with flappy paddles. The 911R should satisfy them—or at least it will if it becomes a regular model in the lineup. If recent history is anything to go by, though, it will more likely be a limited edition that sells out instantly and then commands a hefty premium on the used car market.

Underneath that sloping rear deck—bereft of wings or spoilers other than the retractable one fitted to the regular 911—is a 4L naturally aspirated flat-six engine from the GT3 RS, giving the 911R almost 500hp. Compared to the bewigged GT3 and GT3 RS, the 911R—named for an old Porsche road-legal racer—is meant to be focused on driver enjoyment rather than all-out lap times.

AnyDVD Admins & Developers Mull Comeback

Last week’s demise of SlySoft sent shockwaves through the DVD ripping community with many fearing for the movement’s future. However, just days on and already there are reasons for hope. Key admins and developers are now openly discussing a potential return of AnyDVD, but the road ahead won’t be smooth.

Following pressure from AACS LA, the decryption licensing outfit founded by companies including Warner Bros, Disney, Microsoft and Intel, last week copy-protection circumvention company SlySoft shutdown.

Unusually, the precise reasons for the closure remain uncertain. The only comment made by the company suggests that “regulatory requirements” had caused it to close down. There has been no triumphant announcement from the MPAA either.

That is unusual. One of SlySoft’s flagship products was AnyDVD, a Blu-ray ripping tool that was recently described by the studios as “a source for widespread, large-scale and commercial copyright infringement.” With that product now not on sale, one might think there would be at least some cause for celebration. However, something seems amiss.

For example, while SlySoft as a company says it has shut down, its forums are still operating from a subdomain of SlySoft.com. Interestingly they have just been renamed to RedFox, a nod to the creature depicted in SlySoft’s logo, and the discussion there is certainly providing food for thought and cause for optimism.

Firstly, according to people closely associated with SlySoft, even some key personnel weren’t informed of any potential problems with the company. Only adding to the intrigue is the claim that although SlySoft was shutdown in Antigua, none of the team were based there.

“We all were shocked when [the] message came on Monday to shut down [the] SlySoft website. Staff [still have] no complete information about what really happened and what’s going on in Antigua, as nobody of the SlySoft team is physically based in Antigua. We don’t even know each other,” says an admin identifying himself as ‘Ivan’.

Being scattered in different jurisdictions certainly has its plus points though and Ivan suggests that following lengthy discussion, big things could be on the horizon.

“We (developers and admins) had a few chat conferences this week and we came to the conclusion that if we have the backup of the community, we might consider to continue the development on our own,” he says.

While that is good news for AnyDVD fans, also of interest is that former employees of SlySoft still have access to key Slysoft infrastructure.

James, a now ex-SlySoft developer who says he is “probably the only person on this planet who can actually create an AnyDVD HD release build” says that ex-employees have “control over the assets (sources, servers)”.

But while that’s well and good, he seems less clear over whether those people are free to use them. Furthermore, there are questions over who legally owns AnyDVD if SlySoft itself is out of business.

“If AnyDVD was property of SlySoft, Inc and SlySoft no longer exists, who owns AnyDVD?” he asks.

So at this point questions are being asked based on two theories, or more, depending on how many one is prepared to entertain in this informational vacuum.

Firstly, if SlySoft shut down of its own accord, the company could potentially take legal action against any person resurrecting their products. However, it appears that SlySoft hasn’t parted company with its employees as smoothly as they might have liked, so loyalties don’t appear to be high on the agenda.

“SlySoft, Inc. owes us quite a lot of money, so morally I don’t have too much of a problem,” James says.

While SlySoft may or may not sue, if the shutdown was part of a settlement negotiated with AACS LA and/or the MPAA, it’s feasible those entities might have control of the rights to products including AnyDVD, or at least an agreement that controls their distribution and development.

However, according to key AnyDVD developer James, the latter scenario has not played out.

“I am quite sure, there is no settlement with AACS. The situation would be completely different,” he says.

So what for the future? At this point it’s clearly early days but it does appear that key people with the ability to resurrect products such as AnyDVD are seriously considering their options.

“I mostly worked on AnyDVD, this is my ‘baby’. I can push this forward,” James says.

“I certainly can’t do this on my own. e.g., I can’t maintain the server side, my skills are elsewhere. The other guys (network gurus, other devs, support people, forum mods) need to agree. I have some homework to do now. I’m certain that most of the ex-SlySoft people will agree to move forward.”

This turn of events is not entirely unexpected but there is a long road ahead littered with dozens of obstacles for anyone considering a “RedFox” revival. Nevertheless, with the possibility of release delays on the horizon, thousands will be cheering them on and that will be a hell of a boost.
