No progress in cliff talks leave dollar-euro flat

NEW YORK: The dollar traded flat against the euro Wednesday after a slight push higher mid-session, as talks continued in Washington on averting the economy-crunching fiscal cliff.

At 2200 GMT, the euro bought $1.2939, a hair off the level at the same time Tuesday.

Just hours earlier, the euro fell to $1.2881 before rebounding, the swings apparently related to perceptions over whether the fiscal cliff talks were going well, analysts said.

President Barack Obama suggested key issues were still unresolved with a challenge to Republicans to compromise, deflating the impact of more optimistic remarks earlier by Republican House Speaker John Boehner on progress.

"Our ultimate goal is an agreement that gets our long-term deficit under control in a way that is fair and balanced," Obama said.

"I believe that both parties can agree on a framework that does that in the coming weeks," he said. "In fact, my hope is to get this done before Christmas."

Forex expert Neal Gilbert of GFT was skeptical even of that deadline.

"If no more positive comments are made by the Republican side tomorrow, then we can likely chalk this up to political gamesmanship and resume our regularly scheduled acceleration toward the edge of the fiscal cliff," Gilbert said.

The yen edged higher, with the looming election in Japan limiting any gains as long as the opposition Liberal Democratic Party continues to lead in the polls.

LDP leader Shinzo Abe has vowed to pressure the Bank of Japan into more aggressive monetary easing if his party wins.

The dollar bought 82.03 yen, compared to 82.16 on Tuesday, while the euro was at 106.14 yen, from 106.30.

The dollar was flat against the Swiss franc, trading at 0.9300 francs, and the British pound was also barely changed at $1.6013.

This quadrotor flies -- and rolls -- over just about anything

The cage rotates independently of the central rotor unit in this simple design.

We've seen how flying quadrotors can form spectacular displays in the sky, but what if they could roll along the ground too?

Engineers at the Illinois Institute of Technology's Robotics Lab have been developing a power-efficient machine that can move on land and air. It also happens to be extremely Crave-worthy.

HyTAQ (Hybrid Terrestrial and Aerial Quadrotor) has four rotors that allow it to fly like other quadrotors. But it also has a flexible cylindrical cage around it that acts like a wheel when it's on the ground, as well as an overall shock absorber.

The rotors and the cage use the same actuators and control system, making the HyTAQ light and efficient.

Because it can also drive on the ground, HyTAQ has a greater range than traditional quadrotors given the power it needs.

Experiments show that it can travel four times more and operate almost six times longer than an aerial-only machine, according to the lab.

As seen in the vid below, HyTAQ moves seamlessly from ground to air and back again. Since the cage is made of sturdy polycarbonate and carbon fiber, it can withstand crashing into walls and floors.

Equipped with a camera, it would make a handy reconnaissance drone or a very awesome toy to raise hell with.

Scale it up and you'd have one heck of a sweet ride.

Black Hole Blast Biggest Ever Recorded

Astronomers have witnessed a record-breaking blast of gas and dust flowing out of a monster black hole more than 11.5 billion light-years away.

The supermassive gravity well, with a mass of one to three billion suns, lurks at the core of a quasar—a class of extremely bright and energetic galaxies—dubbed SDSS J1106 1939. (See "Black Hole Blasts Superheated Early Universe.")

"We discovered the most energetic quasar outflow ever seen, at least five times more powerful than any that have been observed to date," said Nahum Arav, an astronomer at Virginia Tech and co-author of the study to be published in The Astrophysical Journal.

Using the powerful telescopes of the European Southern Observatory in Chile, Arav and his team were able to clock the speed and other properties of the outflow.

Belching out material as much as 400 times the weight of our sun every year, the blast is located nearly a thousand light-years from the quasar and has a velocity of roughly 18 million miles (29 million kilometers) per hour.

"We were hoping to see something like this, but the sheer power of this outflow still took us by surprise," said Arav.

The central black hole in this quasar is true giant dynamo. It's estimated to be upward of a thousand times more massive than the one in the Milky Way, producing energy at rates about a hundred times higher than the total power output of our galaxy. (See black hole pictures.)

Clues to Galaxy Evolution

Supermassive black holes are large enough to swallow our entire solar system and are notorious for ripping apart and swallowing stars. But they also power distant quasars and spew out material at high speeds.

(See "Monster Black Holes Gobble Binary Stars to Grow?")

The outflows have been suspected to play a key role in the evolution of galaxies, explained Arav, but questions have persisted for years in the astronomical community as to whether they were powerful enough.

This newly discovered super outflow could solve major cosmic mysteries, including how the mass of a galaxy is linked to its central black hole mass and why there is a relative scarcity of large galaxies across the universe.

"I believe this is the smoking gun for several theoretical ideas that use the mechanical energy output of quasars to solve several important problems in the formation of galaxies and cluster of galaxies," said Arav.

While Kirk Korista, an astronomer not connected to the study, believes these claims may be a bit premature, the research is expected to shed new light on the most powerful and least understood portions of typical quasar outflows.

"The superb spectroscopic data of this quasar have allowed for a breakthrough in quantifying the energetics of what is probably a typical quasar outflow," said Korista, an astronomy professor at Western Michigan University.

"This definitely is an important step in piecing together the story of galaxy evolution, and in elucidating the role of quasars in that story."

Dos, Don'ts of Powerball Office Pools

Powerball fever is sweeping the nation.

The Powerball jackpot is at a record high of $550 million. And with the winnings so high, everyone is rushing to buy a ticket in the hope that they'll be the lucky winner.

A popular means of lotto ticket purchasing is an office pool -- in which a group of colleagues pools their money, buys a slate of tickets together and promises to share the winnings equally. It can be a fun bonding experience with your co-workers, but there are do's and don'ts to abide by, on the off-chance that your ticket(s) have the winning numbers.

DO

Write a Contract

It may seem too serious for what's supposed to be fun and harmless, but this amount of money can make people a little crazy, so it's worth taking precautions. You don't need to draft a formal, notorized document -- a simple piece of paper with the terms of your pool and everyone's signature suffices. Make sure to store a copy of the contract in a safe place.

Make Sure Everyone Contributes an Equal Amount

Sure, if you contribute $2 and your colleague contributes $4, that's not a big difference. But if you win, that colleague will have a claim to 50 percent more of the pool than you, and that will undoubtedly create some office tension.

Photocopy the Tickets for All Participants

Yes, it's unlikely that someone would lie about the tickets outcome, say they lost when they won, claim the money, and then come into the office and continue acting like nothing had happened. But it's unlikely that you're going to win the lottery in the first place, so normal reasoning does not apply here.

Make a List of People Who Opted Out This Time

DON'T

Rely on a Verbal Contract

Words won't hold up in a court of law if someone claims the winning ticket first and runs off with all of the winnings for themselves.

Let Anyone Contribute Money on Behalf of Someone Else

It's a nice idea to include all of your colleagues, even the ones who are out of the office the day you buy the tickets, or short of cash for the pool. But if you do win, those individuals who did not actually put up any of their own money for the tickets will almost certainly not be seen as having a legitimate claim to the winnings.

Trust the Tickets to the Interns

They're working for little to no money, so their loyalty is probably low.

Run Multiple Pools at Once

Gas explosion in Springfield points to ageing pipes

Human error and corroded pipes were a catastrophic combination on 23 November when a natural gas explosion in Springfield, Massachusetts, injured 21 people and damaged more than 40 buildings.

Gas company officials attributed the incident to an employee puncturing a high-pressure pipeline with a metal probe while looking for a leak. However, the steel pipeline was highly corroded, making it susceptible to damage, according to Mark McDonald, president of the New England Gas Workers Association. "You would have to be Superman to go through steel pipe in good condition," he says.

Ageing natural gas pipelines in the US are increasingly coming under scrutiny. A recent study found 3356 leaks from pipelines under Boston alone. Twenty-five thousand leaks have been reported throughout Massachusetts, some of which have been leaking continuously for more than 20 years, McDonald says. "Enough is enough," he says. "We have to fix the leaks and maintain the gas lines."

The leaks raise safety concerns, and have implications for global warming. Methane is thought to be more than 20 times more effective at trapping heat in the atmosphere than carbon dioxide over a 100 year period.

Incidents involving natural gas pipelines in the US cause an average of $133 million in property damage each year according to data collected by the US Pipeline and Hazardous Materials Safety Administration. Even accounting for inflation, annual damages are several times higher today than they were 20 years ago.

Euro sags after new Greek debt deal sealed

NEW YORK: The euro fell against the dollar Tuesday following a week of gains after the European Union and IMF reached agreement on recasting Greece's bailout to avert a looming default.

But the dollar's gains were limited by signs that negotiations in Washington over the looming fiscal cliff, remained divided on key issues.

At 2200 GMT the euro was at $1.2938, down from $1.2971 at the same time Monday.

The yen was mixed, falling to 82.16 yen per dollar from 81.98 yen Monday, but gaining to 106.30 yen per euro from 106.38.

Neal Gilbert of GFT said profit taking set in on the euro after its rise ahead of the Greek debt talks Monday.

"The Eurogroup worked overtime yesterday to finally come to an agreement on Greece after two postponements delayed it into this week," Gilbert said.

"In response, risk markets rose, but not as handily as some had expected. The euro-dollar in particular barely reached $1.30 from $1.2960 before profit taking shoved it back down toward the $1.29 handle throughout the US trading session."

Greece won breathing space with long-frozen eurozone loans to restart from December and a first clear admission that a chunk of the country's debt burden will eventually have to be written off.

After 13 hours of talks in Brussels, the eurozone and the International Monetary Fund agreed to unlock 43.7 billion euros ($56 billion) in loans and on the need to grant significant debt relief for decades to come.

Greece must still meet a series of agreed conditions but "the decision will certainly reduce the uncertainty and strengthen confidence in Europe and in Greece," said European Central Bank President Mario Draghi who left the talks before a final press conference.

Meanwhile Gilbert said he expected the yen to slip further ahead of the December 16 Japanese election, with the opposition Liberal Democratic Party leading in the polls.

LDP leader Shinzo Abe has vowed to pressure the Bank of Japan into launching aggressive monetary easing measures if his party wins.

"Since Abe's LDP party is expected to be victorious in the December 16 elections, the yen may well continue to depreciate," said Gilbert.

In other currencies, the Chinese yuan was steady as the US Treasury ruled against labeling Beijing a currency manipulator, trading at 6.227 yuan per dollar, shy of the record high of 6.220 hit on Monday.

The dollar rose to 0.9306 Swiss francs from 0.9278 francs.

The British pound fell to $1.6019 from $1.6026.

Google CEO said to meet with FTC over antitrust probe

Google's effort to persuade investigators that it hasn't violated antitrust laws may be reaching its final stages, with CEO Larry Page reportedly meeting with the U.S. Federal Trade Commission officials today in Washington.

Citing a person familiar with the discussions, Bloomberg reports that Page met with officials in the last days of a 19-month investigation into Google's business practices. The company has been having settlement talks with the FTC for "about a week," Google reported, and is resisting pressure to enter into a consent decree affecting Google's products.

The FTC has investigated a wide range of Google's business practices, focused on two key areas: the way Google displays search results, which critics say favor the company's own services over those of its competitors; and its decisions around technology licensing, which some argue are anticompetitive. (At a business conference today, Yelp CEO Jeremy Stoppelman railed against Google's search results strategy.)

Bloomberg previously reported that the FTC had issued an ultimatum to Google pressuring the company to settle. But there have been lingering questions over whether the FTC can make an airtight case that Google has broken the law. U.S. Sen. Ron Wyden wrote a letter to the FTC on Monday expressing concerns over rampant leaks from the investigation, along with reports that the FTC was considering novel new applications of the law in order to make its case.

Google, for its part, repeated a previous statement that it is working with the FTC and is happy to answer officials' questions. It declined further comment to Bloomberg, as did the FTC.

Pictures: Falcon Massacre Uncovered in India

Photograph courtesy Conservation India

A young boy can sell bundles of fresh Amur falcons (pictured) for less than five dollars. Still, when multiplied by the thousands of falcons hunters can catch in a day, the practice can be a considerable financial boon to these groups.

Since discovering the extent of Amur hunting in Nagaland this fall, Conservation India has taken the issue to the local Indian authorities.

"They have taken it very well. They've not been defensive," Sreenivasan said.

"You're not dealing with national property, you're dealing with international property, which helped us put pressure on [them]." (Related: "Asia's Wildlife Trade.")

According to Conservation India, the same day the group filed their report with the government, a fresh order banning Amur hunting was issued. Local officials also began meeting with village leaders, seizing traps and confiscating birds. The national government has also requested an end to the hunting.

Much remains to be done, but because the hunt is so regional, Sreenivasan hopes it can eventually be contained and stamped out. Authorities there, he said, are planning a more thorough investigation next year, with officials observing, patrolling, and enforcing the law.

"This is part of India where there is some amount of acceptance on traditional bush hunting," he added. "But at some point, you draw the line."

Egypt Erupts Over Morsi's 'First Step for Tyranny'

Nov 27, 2012 1:33pm

CAIRO – Waves of protesters poured into Cairo’s Tahrir Square today to protest the far-reaching constitutional declaration made by President Mohammed Morsi last week that has essentially granted him unchecked power.

Click here for images of the demonstrations in Tahrir Square.

The new declaration frees Morsi from judicial oversight and with no parliament currently in place, many said longtime dictator Hosni Mubarak had simply been substituted with another.

“This is the first step for tyranny, he’s trying to put all the power in his hands and this is against the constitution and the law,” said Hassan Gamal, a professor of orthopaedic surgery. “No exceptions for anybody. Mubarak was tyrant because of the exceptions. We’re not going to tolerate any exceptions anymore.”

Liberal groups had called for the mass protest against Morsi, many of which have long complained of Islamists’ strength in post-Mubarak Egypt, led by Morsi and the Muslim Brotherhood. Protesters today said they were afraid of the constitution being written by an Islamist-dominated constitutional assembly, which will be put to a referendum once finished.

“The Muslim Brotherhood, they say something and then do the opposite,” said English teacher Nadine Mustafa. “We are in the 21st century, we want democracy, we don’t want a pharaoh ruining the country. This is ridiculous.”

Morsi’s office published the seven-article declaration on Thursday, the second of which states that Morsi’s laws and decrees “are final and binding and cannot be appealed by any way or to any entity” until the constitution is approved and a parliament elected.

Violence immediately broke out with clashes between Morsi opponents, supporters and police leading to more than 500 injuries and at least three deaths. To prevent more violence, the Muslim Brotherhood on Monday night cancelled their own rallies planned for today, though supporters did turn out in Alexandria.

“He’s a president that was elected to office with no constitution, no parliament and no defined powers in the state. It’s an exceptional circumstance,” argued Muslim Brotherhood senior adviser Jihad Haddad, who accused Mubarak-appointed judges of blocking Morsi’s attempts to reform the country’s institutions.

Morsi’s office insisted that the powers are only temporary. Haddad said the declaration will only be valid until a draft of the constitution is submitted.

“[Morsi] tried to do this through the only available avenue and choice,” Haddad said. “It does terrify [Morsi opponents] because the only thing they can rely on is trust and that trust was given to us during the presidential elections.”
