First direct detection sheds light on dark galaxies

ScienceDaily (Oct. 30, 2012) ? Most people think of galaxies as huge islands of stars, gas and dust that populate the universe in visual splendor. Theory, however, has predicted there are other types of galaxies that are devoid of stars and made predominately of dense gas. These "dark" galaxies would be unseen against the black backdrop of the universe.

Now, an international team of astronomers has detected several dark galaxies by observing the fluorescent glow of their hydrogen gas, illuminated by the ultraviolet light of a nearby quasar. But what exactly are dark galaxies, and what role do they play in the evolution of our universe?

"Dark galaxies are composed of dark matter and gas, but for some reason they have not been able to form stars," said Martin Haehnelt, Kavli Institute for Cosmology at the University of Cambridge. "Some theoretical models have predicted that dark galaxies were common in the early universe when galaxies had more difficulty forming stars -- partly because their density of gas was not sufficient to form stars -- and only later did galaxies begin to ignite stars, becoming like the galaxies we see today."

Haehnelt is a member of the scientific team that detected these galaxies. According to Haehnelt, one can begin to understand the importance of dark galaxies by looking at our own Milky Way. "We expect the precursor to the Milky Way was a smaller bright galaxy that merged with dark galaxies nearby. They all came together to form our Milky Way that we see today."

Another member of the team, Sebastiano Cantalupo of the University of California, Santa Cruz, agreed that dark galaxies are the building blocks of modern galaxies. "In our current theory of galaxy formation, we believe that big galaxies form from the merger of smaller galaxies. Dark galaxies bring to big galaxies a lot of gas, which then accelerates star formation in the bigger galaxies."

The techniques used for detecting dark galaxies also may provide a new way to learn about other phenomena in the universe, including what some call the "cosmic web" -- unseen filaments of gas and dark matter believed to permeate the universe, feeding and building galaxies and galaxy clusters where the filaments intersect.

"I wonder if we can indeed use this technique to see the emission of filamentary gas in the cosmic web, and if so, how close are we to seeing that?" said team member Simon Lilly of the Swiss Federal Institute of Technology in Zurich, Switzerland. "That has been something of a Holy Grail for many, many years and I think this most recent discovery of dark galaxies is a significant step toward the goal."

Vegan Recipes | Baked Cinnamon Donuts ? Like A Vegan

October 20, 2012 0

Difficulty: Medium

Makes 12

Oh. My. God. Why have I not made donuts before?! To be honest, it just didn?t strike me as worth it until I started to crave them recently but I?ll be the first to admit I?m an absolute IDIOT for not trying them until now. While they do take some time to make, the results speak for themselves and you?ll have your friends and family begging you for more! Stay tuned for many more donut recipes, I?ve got a feeling I?ll be making them much more often.

Ingredients

• 1 cup soy milk
• 1 teaspoon apple cider vinegar
• 7 gram packet dry yeast
• 1/4 cup Nuttelex, melted
• 1 teaspoon vanilla
• 3/4 cup caster sugar
• 2 1/2 cups plain flour
• Spray oil
• 2 teaspoons ground cinnamon

Method

1. Warm your milk in in the microwave for a minute before whisking through the apple cider vinegar and setting aside for a few minutes.
2. Pop the mixture into a large bowl before adding the yeast and ?1 tablespoon of melted butter. Allow to sit for a few moments before adding the vanilla and 1/4 cup of caster sugar.
3. Sift in the flour and combine well in the bowl before tipping out onto a lightly floured surface.
4. Knead with your palms for about 10 minutes until the dough is smooth.
5. Spray a large bowl with spray oil and roll the dough around to coat it. Cover and allow to rise for one hour.
6. Preheat the oven to 200?C and line two baking trays with baking paper.
7. Punch down the dough and tip out onto a lightly floured surface. Give it another light knead for a couple of minutes before rolling the dough out to be about 2cm thick.
8. Now you need to cut out your donut shapes! If you?re going for your traditional donut shape, you can cut out using a large drinking glass and making the hole with a small lid (from an olive oil bottle for example). This will give you a regular sized donut. You may need to re-roll the dough to get the full dozen donuts but hang onto the holes and any excess dough.
9. Space your donuts out six to a tray, you can scatter the holes on the trays too. Cover each tray with a tea towel and allow the donuts to rise for another half an hour.
10. Pop the trays in the oven and cook for about 10-15 minutes, until they?re lightly golden.
11. Allow to cool for about 10 minutes. In the meantime you can combine the remaining sugar and cinnamon in a shallow bowl.
12. With a pastry brush, cover each donut with melted Nuttelex before dunking in the cinnamon mixture. Make sure it?s evenly coated and gently shake of the excess.
13. Best served warm but will keep for a couple of days.

Skywalk case goes before federal appellate court

SAN FRANCISCO (AP) ? A Las Vegas developer has been bounced between tribal and federal court in an effort to protect his financial interest in the Grand Canyon Skywalk, a popular glass bridge that extends from the canyon's edge on tribal land in western Arizona.

On Friday, David Jin's attorneys will argue before the 9th Circuit U.S. Court of Appeals that the Hualapai tribal court system hasn't given Jin a fair shot and that he shouldn't have to fight his legal battles there.

The tribe has denied those allegations and will urge the San Francisco court to uphold a ruling that said Jin first must exhaust remedies in tribal court. By signing a contract with a business arm of the tribe in 2003, Jin allowed it to be governed by Hualapai law, the tribe said.

Jin invested $30 million to build the horseshoe-shaped bridge that gives visitors a view of the Colorado River 4,000 feet below. He and the Hualapai Tribe have been locked in a contract dispute that led the tribe to sever the contract with Jin and for Jin to pursue legal action for alleged constitutional violations.

The contract dispute itself isn't up for review by the appellate court, only the jurisdictional question. There is an exception to exhausting tribal court remedies if Jin's attorneys can prove that the tribal court ? not the Tribal Council ? has acted in bad faith. He's been unsuccessful so far.

Jin also argues that the tribal court lacks civil jurisdiction over him and the corporation he formed to manage the Skywalk, the Nevada-based Grand Canyon Skywalk Development.

No court has ruled on Jin's claims that he is owed for years of unpaid management fees or the tribe's claims that Jin failed to complete a visitor center. A tribal court judge rejected an attempt by Jin to force arbitration because the tribal defendants are protected from lawsuits by sovereign immunity. The federal District Court repeatedly has said that the tribal court has the first right to hear the case. The two sides don't agree on an arbiter's decision to award Jin about $28 million in the contract dispute.

DC Comics wins crucial victory in Superman legal battle | Robot 6 ...

From Action Comics #1

Handing a major victory to DC Comics, a California federal judge has ruled the heirs of Superman co-creator Joe Shuster surrendered the ability to reclaim their 50-percent interest in the property in a 1992 agreement with the publisher.

While the decision likely will be appealed, for now it means DC and parent company Warner Bros. can use the Man of Steel any way they wish beyond Oct. 26, 2013, when the Shuster estate would have recaptured its copyright to the first Superman story in 1938?s Action Comics #1. However, the companies must account for any profits earned from the property with the family of co-creator Jerry Siegel, which reclaimed its share in 2008 through a provision of the U.S. Copyright Act (the scope of that decision is on appeal). Had the Shuster estate succeeded, DC and Warner Bros. eventually would have been unable to use many of the character?s defining aspects, including his secret identity, his origin, certain elements of his costume and powers (super-strength and super-speed), and Lois Lane ? barring a new agreement with the families of the two creators, naturally.

On Wednesday, U.S. District Judge Otis D. Wright granted DC?s motion for partial summary judgment on the issue of whether the Shuster estate?s 2003 copyright-termination notice was invalidated by a 20-year-old agreement with the late artist?s sister Jean Peavy. The publisher had argued the family relinquished all claims to the Man of Steel in 1992 in exchange for ?more than $600,000 and other benefits,? including payment of Shuster?s debts following his death earlier that year and a $25,000 annual pension for Peavy.

Although Wright appeared somewhat swayed by the argument made last month by Shuster attorney Marc Toberoff that DC never intended the ?ambiguous? document to transfer ownership of copyright to ?a billion-dollar property,? the judge ultimately found ?that the 1992 agreement, which represented the Shuster heirs? opportunity to renegotiate the prior grants of Joe Shuster?s copyrights, superseded and replaced all prior grants of the Superman copyrights.?

Indeed, Wright noted that when DC increased survivor benefits from $5,000 to $25,000 a year, Peavy said she understood and agreed to the admonition from then-Executive Vice President Paul Levitz that, ?this agreement would represent the author/heir?s last and final deal with DC, and would fully resolve any past, present, or future claims against DC.? The judge also pointed out that under a 1975 agreement with Siegel and Shuster, DC provided each of the two creators with lump sums (in today?s dollars) of $75,000 and lifetime annual payments of $80,000, survivor benefits and insurance ? ?as well as ?credits? on new Superman works? ? amounting to more than $4 million (not counting medical benefits and ?bonuses?).

In a statement to The Hollywood Reporter, Toberoff, who also represents the Siegel family, said, ?We respectfully disagree with its factual and legal conclusions, and it is surprising given that the judge appeared to emphatically agree with our position at the summary judgment hearing.?

The trade paper suggests, however, that Toberoff may find cause for appeal in Wright?s comment that, ?The broad and all-encompassing language of the 1992 agreement unmistakably operates to supersede all prior grants.?

Still ahead is a Nov. 5 hearing before the 9th Circuit Court of Appeals in which DC will argue the 2008 ruling that found the Siegel family had reclaimed its stake in Superman should be overturned. Toberoff will also seek to define precisely what elements of the characters are covered by the decision.
