Euro gains against US dollar in positive market






NEW YORK: The euro gained ground against the US dollar Monday as positive market sentiment spurred buying of riskier assets, such as the European currency.

The euro fetched US$1.3376 around 2200 GMT, up from US$1.3341 at the same time last Friday. Earlier, the unit brushed US$1.3404, its highest level in almost 11 months.

The euro continued to rise against the Japanese currency, to 119.65 yen from 119.00 yen late Friday, while the US dollar rose to 89.45 yen from 89.18 yen.

The market showed little reaction to a speech by Federal Reserve Chairman Ben Bernanke on the challenges facing the US economy, analysts said.

"I saw nothing very different from what has already been announced by the Fed," whether it be in the minutes from the last Federal Open Market Committee policy meeting in December or the FOMC statement, Charles St-Arnaud, a Nomura economist, said.

Wading into the Washington political fray over the federal budget and the borrowing limit, Bernanke called on Congress to lift the debt limit to avoid putting the country into default.

Kathy Lien of BK Asset Management said the market was waiting for Tuesday's US retail sales data for December, which covers the important holiday-shopping season.

"Consumer spending is the backbone of the US economy, and the only reason why investors obsess over the labour market is because they hope that stronger job growth will translate into stronger spending," Lien said.

The euro rise was buoyed by last week's upbeat comments by European Central Bank president Mario Draghi.

The yen, meanwhile, remained under selling pressure after Japanese Prime Minister Shinzo Abe on Friday unveiled a US$226.5 billion stimulus plan in the latest bid to boost the world's fragile number-three economy.

The US dollar rose against the Swiss currency, buying 0.9216 francs compared with 0.9135 francs late Friday.

The pound fell to US$1.6074 from US$1.6129.

Poll: After Newtown, Most Back Some Gun Controls


gty gun store mi 130114 wblog After Newtown Shootings, Most Back Some Gun Controls, Poll Shows

Getty Images


A majority of Americans favor such gun control measures as banning assault weapons and expanding background checks on those who buy guns and ammunition, with support for banning high-capacity ammunition magazines at a new high in ABC News/Washington Post polls.

With Vice President Joe Biden set to present recommendations that were prompted by the Newtown, Conn., school shootings last month, this latest poll shows overwhelming support for certain moves: Eighty-eight percent favor background checks on firearms buyers at gun shows; 76 percent support checks on buyers of ammunition and 71 percent back a new federal database that would track all gun sales.


For full results, charts and tables, CLICK HERE


Sixty-five percent also support banning high-capacity ammunition magazines, a high in three ABC/Post polls to test the idea since early 2011, and up by 6 percentage points since just after the Newtown shootings. Among other suggestions, 58 percent favor banning the sale of so-called assault weapons, 55 percent support the National Rifle Association’s call for armed guards in schools and 51 percent would ban semi-automatic handguns.


Notably, support for the most popular of these measures – expanded background checks, a gun database and banning high-capacity magazines – includes a majority of people who live in gun-owning households, a group that accounts for 44 percent of all adults in this country.


The intensity of support for all these proposals is also notable; “strong” support for each measure outstrips strong opposition, in most cases by overwhelming margins (save the two less-popular items, armed school guards and a semi-automatic handgun ban). For instance, 50 percent “strongly” favor banning assault weapons, twice the number who strongly opposes it. And 76 percent strongly support background checks at gun shows, while only 8 percent say they’re are strongly opposed.


Fifty-five percent in this poll, produced for ABC by Langer Research Associates, express worry about a mass shooting in their own communities, and 52 percent say the Newtown shootings have made them more likely to support some forms of gun control.


As noted, support for banning high-capacity magazines is at a new high in polling since 2011. But there’s no consistent change on other proposals. Support for background checks on gun show buyers is essentially the same as it was in the late 1990s; support for banning assault weapons is numerically up from its low in 2009  but still well below its levels in the mid- to late 1990s; and support for banning semi-automatic handguns has been essentially steady in recent years.


ACTION – Looking ahead to the possibility of legislative action, most Americans give the issue at least a high priority for the president and Congress to address, but not “the highest,” and more give greater priority to  ”addressing gun violence” (68 percent) than specifically “enacting stricter gun control laws” (59 percent).


While they reach majorities, both of these are lower on the list than other top-shelf issues, including the economy, cutting federal spending, restructuring the tax system and slowing the rate of growth in spending on Social Security and Medicare.


The higher priority for “addressing gun violence” versus “enacting stricter gun control laws” (in a split-sample test) likely reflects some compunctions about whether gun control measures will work. The public, for instance, divides on whether stricter gun laws or armed guards in schools would be more effective (43-41 percent), and as many or more blame gun violence on inadequate treatment of the mentally ill, and on irresponsibility among gun owners, as on other causes.


FACTORS – Many factors receive broad blame for gun crimes. Leading the list, more than eight in 10 see inadequate treatment of the mentally ill, inadequate background checks and lack of individual responsibility by gun owners as contributors to gun violence, and more than half, in each case, say these contribute “a great deal” to the problem.


Sixty-nine to 73 percent also see the availability of semi-automatic handguns, high-capacity ammunition clips and assault weapons as contributors – yet as many say the same about the prevalence of violence in TV programs, movies and video games. The fewest numerically, 38 percent, believe violence in the media contributes “a great deal” to gun violence.


There are three items on which more people say the issue contributes to gun violence than favor legislative action: Sixty-nine percent see access to semi-automatic handguns as a contributor, versus 51 percent who favor banning such weapons; 73 percent say assault weapons are a contributor, versus 58 percent who favor banning those; and 70 percent see high-capacity magazines as a factor in gun violence, while slightly fewer, 65 percent, would ban them. The gaps apparently exist at least in part because support for action is lower among those who see these as contributing “somewhat” but not a great deal to gun violence – a group that includes more pro-gun individuals, such as people in gun-owning households, men and political conservatives.


GROUPS – There are striking differences among groups on some, but not all, gun control issues. Support for gun control measures generally is higher among women than men, with the gap peaking on a ban on semi-automatic handguns, supported by 60 percent of women versus 40 percent of men.


In addition to the expected partisan and ideological divisions, support for gun control also is higher in several cases among senior citizens vs. the youngest adults, among city dwellers vs. those in suburbs or rural areas, in Democratic-voting blue states vs. more-Republican red states, and in non-gun households vs. those in which someone owns a firearm. There also are regional divisions, with support for gun control typically highest in the Northeast and lowest in the South.


These differences, however, generally fade on the issues on which agreement is most broad – background checks, a gun database and banning high-capacity magazines.


Patterns are different in support for armed guards in schools; this idea is more popular with conservatives versus liberals (63 versus 44 percent), in red versus blue states (67 versus 49 percent) and among Republicans versus Democrats and independents (65 versus 52 percent). It also gets more support from parents with minor children, 62 percent, versus 51 percent among other adults. In the biggest gap, the proposal for armed school guards is nearly 30 points more popular with people who see the NRA’s leadership favorably than among those who see it unfavorably, 69 versus 40 percent.


There are other differences among groups that inform views on gun control. Women, for instance, are 13 points more apt than men to say the Newtown shootings have made them more likely to support some forms of gun control, and 16 points more likely to be worried that a mass shooting could occur in their own area. That worry is a prime factor in support for stricter gun laws.


THE NRA – While recent polls have found the NRA to be popular overall with a majority of Americans, this survey finds a less positive assessment of the association’s leadership -  more see it unfavorably than favorably by an 8-point margin, 44 versus 36 percent, although many don’t know enough to say.


There’s a mixed result on the NRA’s influence on gun policy; on the one hand more, 38 percent, say it has too much influence versus too little (24 percent) or about the right amount (30 percent). At the same time, that makes a majority, netted, saying its influence is too little or about right.


The NRA’s leadership, naturally, has far more support among people in gun-owning versus non-gun-owning households – a 52 percent versus 22 percent favorable rating. Similarly, 49 percent in non-gun households say the NRA has too much influence over gun laws. In gun households 27 percent, agree.


METHODOLOGY – This ABC News/Washington Post poll was conducted by telephone Jan. 10-13, 2013, among a random national sample of 1,001 adults, including landline and cell-phone-only respondents. Results have a margin of sampling error of 3.5 points, including design effect. Partisan divisions are 33-24-37 percent, Democrats-Republicans-independents.


The survey was produced for ABC News by Langer Research Associates of New York, N.Y., with sampling, data collection and tabulation by Abt-SRBI of New York, N.Y.

Benefits of emissions cuts kick in only next century









































Are we the altruistic generation? Do we care what happens to our grandchildren, and to their children? Or are we with Groucho Marx when he said: "Why should I care about future generations? What have they ever done for me?"











A new study of climate change lays out in detail why this matters. According to its author, Nigel Arnell of the University of Reading, UK, the unpalatable truth is that even rapid action now to curb greenhouse gas emissions would have only a "negligible effect by 2030, and the benefits in 2050 would remain small". The big dividend – cooler temperatures, fewer floods and droughts and better crop yields, compared to carrying on as we are – would only become clear by about 2100.












Arnell and colleagues used climate models to look at how different policies to curb greenhouse gases would affect temperature, sea levels, crop yields and the incidence of droughts and floods. Two findings emerged. The first is that lags in the climate system mean the real benefits of cutting emissions will only show up late this century. This, says Arnell, underlines that there is a lot of global warming "in the pipeline" that cannot now be prevented.












But the study also shows that tackling climate change early brings big rewards. Arnell compared a policy of letting emissions peak in 2016 and then cutting them by 2 per cent a year with one that delays the peak till 2030 and then cuts by 5 per cent a year. He found that both restricted warming in 2100 to about 2 °C, but the climate disruption over the next century would be much less with the early start. Coastal flooding from sea-level rise in particular would be much reduced. This, he told New Scientist, contradicts a common view that drastic action to curb warming should wait for renewable energy to become cheaper.













"Arnell has shown just how crucial the emissions pathway we take today will be for our children and grandchildren," said Dave Reay, geoscientist at the University of Edinburgh, UK. Bill McGuire of University College London agrees: "It shows taking effective action now is far better than putting it off until later."












It's a shame, then, that even if all goes well with UN negotiations, no global deal to bring down emissions will come into force until at least 2020. Our great-great-grandchildren will be cursing our delay.

US played 'limited' role in botched French rescue bid






WASHINGTON: The United States said Sunday it played a limited support role in France's botched bid to rescue a kidnapped secret agent in Somalia.

"United States forces provided limited technical support to the French forces in that operation, but took no direct part in the assault on the compound where it was believed the French citizen was being held hostage," President Barack Obama said in a letter to Congress.

Saturday's failed attempt to free the French hostage from the Al Qaeda-linked Shebab group killed at least eight civilians, as well as 17 guerrillas. One French soldier died while another went missing.

"United States combat aircraft briefly entered Somali airspace to support the rescue operation, if needed," Obama wrote, adding that "these aircraft did not employ weapons during the operation."

"I directed U.S. forces to support this rescue operation in furtherance of U.S. national security interests," he wrote.

Oracle releases software update to fix Java vulnerability




Oracle released an emergency software update today to fix a security vulnerability in its Java software that could give allow attackers to break into computers.


The update, which is available on Oracle's Web site, fixes a critical vulnerability in Oracle's Java 7 that could allow a remote, unauthenticated attacker to execute arbitrary code. The attack can be induced if someone visits a Web site that's been set up with malicious code to take advantage of the hole.


Oracle said the update modifies the way Java interacts with Web applications.


"The default security level for Java applets and web start applications has been increased from 'medium' to 'high," Oracle said in an advisory today. "This affects the conditions under which unsigned (sandboxed) Java web applications can run. Previously, as long as you had the latest secure Java release installed applets and web start applications would continue to run as always. With the 'high' setting the user is always warned before any unsigned application is run to prevent silent exploitation."


The vulnerability was being exploited by a zero-day Trojan horse called Mal/JavaJar-B, which was already identified as attacking Windows, Linux and Unix systems and being distributed in exploit kits "Blackhole" and "NuclearPack," making it far more convenient to attackers.

Pictures: Civil War Shipwreck Revealed by Sonar

Photograph by Jesse Cancelmo

A fishing net, likely only decades old, drapes over machinery that once connected the Hatteras' pistons to its paddle wheels, said Delgado.

From archived documents, the NOAA archaeologist learned that Blake, the ship's commander, surrendered as his ship was sinking. "It was listing to port, [or the left]," Delgado said. The Alabama took the wounded and the rest of the crew and put them in irons.

The officers were allowed to keep their swords and wander the deck as long as they promised not to lead an uprising against the Alabama's crew, he added.

From there, the Alabama dropped off their captives in Jamaica, leaving them to make their own way back to the U.S.

Delgado wants to dig even further into the crew of the Hatteras. He'd like see if members of the public recognize any of the names on his list of crew members and can give him background on the men.

"That's why I do archaeology," he said.

Dreamliner Nightmare: Another 787 Fuel Leak













Japan Airlines said a Boeing 787 Dreamliner jet leaked fuel while undergoing tests today at the airport near Tokyo, marking the latest in a string of highly-publicized problems for the jetliner as it undergoes a safety review by the U.S. government.


The Dreamliner being examined leaked around 25 gallons of fuel from a nozzle in the left wing, according to a spokesperson for Japan Airlines. It was reportedly the same aircraft that spilled fuel onto the runway at Logan International Airport in Boston earlier this week, The Associated Press reported.


On Monday, firefighters battled an electrical fire on a grounded Japan Airlines 787, also at Logan.


"We are aware of the event and are working with our customer," Boeing spokesman Marc Birtel said in an email to the Los Angeles Times.


The jetliner, which was unveiled as a luxurious and fuel-efficient way to travel, has recently been beset by problems.

Dreamliner Set to Change the Face of Flight Watch Video





Japan's All Nippon Airways has reported a fuel leak, a 3-foot-long crack in a cockpit window and a malfunctioning computer in its fleet of 787s.


The Federal Aviation Administration announced a comprehensive review of the carbon-fiber plane to ensure it is safe to fly, however officials did not waver in their support of the aircraft.


"I would fly on one today," Transportation Secretary Ray LaHood said at a joint news conference with Boeing on Friday.


The plane will not be grounded by the FAA, and will continue to fly during the review, FAA administrator Michael Huerta said.


"Nothing suggests the airplane is not safe," Huerta said. "We believe this is a safe aircraft. To validate the work during the certification process, we'll work with Boeing to check on systems design and production.


"We want to make sure that the approved quality-control process is in place. We want to see the entire picture and not focus on individual events, to determine the root causes of these events," he said.


Huerta said the review will focus on the Dreamliner's electrical system, including the battery and the power distribution panels, and how electrical and mechanical systems interact with one another.


Aviation experts say that, except for the fire, the issues have all been minor.


"If there was something seriously wrong with this plane there is no question they would ground it," ABC News aviation consultant John Nance said. "That's not the problem here, there's nothing seriously wrong with the 787."
