European Space Agency scientists think that there was and could even still be life on Mars and want a new European mission to the red planet to take samples, a conference heard in Noordwijk, The Netherlands heard on Friday, February 25, 2005.

MOSCOW | Thu Mar 14, 2013 3:37pm EDT

MOSCOW (Reuters) - Europe and Russia signed a deal on Thursday for a joint Mars mission which will bore beneath the Red Planet's surface for soil samples they hope will solve the mystery of whether there is life beyond Earth.

Europe's space agency had hoped to work with NASA on the two-spacecraft ExoMars mission but turned to the Russians after the U.S. agency pulled out due to budget shortfalls.

The announcement comes amid heightened excitement over the search for life on the planet in our solar system most like Earth after scientists said analysis from NASA's own mission rover, Curiosity, showed Mars had the right ingredients for life.

European scientists say the two-stage mission, with the two craft to be launched in 2016 and 2018, will pave the way for what NASA has described as the "Holy Grail" of Mars exploration: a separate mission to return dirt samples from the Red Planet.

"Curiosity learnt us a little bit, ExoMars will bring us a step further, but bringing back those samples to Earth you can do 10 to 100 times more analysis," Rolf de Groot, head of the European Space Agency's (ESA) Robotic Exploration Coordination Office, told Reuters.

"That is a goal of everybody who works on Mars exploration."

The Europe-Russia mission hopes to take scientists beyond NASA's finding that the surface of Earth's neighboring planet had the right mix of elements to sustain life, by drilling 2 meters (6 feet) below its radiation-hit surface for samples.

"NASA is also drilling, but two centimeters deep," de Groot said, referring to the ongoing Curiosity mission. "It's a completely different story."

"ExoMars, by drilling 2 meters into the ground, might hope to identify really the big molecules because that would be a direct indication of the presence of life or that life once existed on Mars."

He said the ESA's Mars rover would also be equipped with a much more advanced laboratory than Curiosity has, so would be able to carry out more detailed analysis.

RUSSIAN ROCKETS

Russian Space Agency Roskosmos will provide the rockets to launch the ExoMars - short for Exobiology on Mars - mission and will also design the descent module and surface platform.

Europe turned to Russia after NASA left the $1.3 billion project in February 2012, citing a budget crunch. The ESA and Roskosmos agreed to cooperate last April, but talks to work out the details dragged on for nearly a year.

"This event was a long time in the making and took a great deal of collaboration," Roskosmos head Vladimir Popovkin said after signing the deal with ESA Director Jean-Jacques Dordain in Paris.

Russia's involvement in the ambitious mission could boost the status of its once-pioneering space agency after a litany of costly and embarrassing failures.

The delays in agreeing the mission hinged on the extent of Russia's participation, according to Russian space experts who said Moscow had seemed to reach its goal of full partnership.

"The agreement implies that Russian scientists and engineers will become full-fledged participants in all the international scientific and technical groups," Roskosmos said in a statement.

What was to be Russia's first deep space mission in more than two decades - the Phobos-Grunt mission to scoop up soil samples from Mars - was among five botched launches that damaged Moscow's reputation as a reliable launch partner.

European governments have so far committed 850 million euros to the mission. The funding cap has been set at 1 billion euros ($1.3 billion) but delays and changes to the scientific aspects of the project are expected to drive up the price tag.

Even though NASA pulled out, it will still provide radio communications equipment, an important organics experiment and engineering and mission support.

The United States also plans to follow up its Curiosity rover with an identical probe, to launch in 2020. It has not yet decided if it will cache samples for a future return to Earth.

The U.S. National Academy of Sciences in 2011 ranked a Mars sample return mission as its top priority in planetary science for the next decade. The long-term goal of the U.S. human space program is to land astronauts on Mars in the 2030s.

A computer screen is pictured before a scientific seminar to deliver the latest update in the search for the Higgs boson at the European Organization for Nuclear Research (CERN) in Meyrin, near Geneva July 4, 2012.

GENEVA | Thu Mar 14, 2013 11:08am EDT

GENEVA (Reuters) - Physicists who last summer triumphantly announced the discovery of a new particle but held back from saying what it was, declared on Thursday there was now little doubt it was the long-sought Higgs boson.

Latest analysis of data from the Large Hadron Collider (LHC) particle accelerator, where the boson was spotted as a bump on a graph early in 2012, "strongly indicates" it is the Higgs, said CERN, the European Organisation for Nuclear Research.

Physicists believe the boson and its linked energy field were vital in the formation of the universe after the Big Bang 13.7 billion years ago by bringing flying particles together to make stars, planets and eventually humans - giving mass to matter, in the scientific jargon.

The particle and the field, named for British physicist Peter Higgs who predicted their existence 50 years ago, are also the last major missing elements in what scientists call the Standard Model of how the cosmos works at the very basic level.

But the CERN statement stopped short of claiming a discovery - which would clear the way to Nobel prizes for scientists linked to the project - and floated the idea that this might be an exotic "super-Higgs" offering a key to new worlds of physics.

"It remains an open question whether this is the Higgs boson of the Standard Model ... or possibly the lightest of several bosons predicted in some theories that go beyond the Standard Model," said CERN, a large complex on the edge of Geneva.

"Finding the answer to this question will take time."

Although some CERN physicists privately expressed irritation at the continuing refusal to - as one said - "call a Higgs a Higgs", others argued that this could only come when the evidence was all totally irrefutable.

If it is not what one CERN-watching blogger has dubbed a "common or garden Higgs" but something more complex, vistas into worlds of supersymmetry, string theory, multiple dimensions and even parallel universes could begin to unfold.

WHAT KIND OF HIGGS?

"To me it is clear that we are dealing with a Higgs boson, though we still have a long way to go to know what kind of Higgs boson it is," said Joe Incandela, spokesman for CMS, one of the two independent CERN LHC monitoring teams.

"There is every possibility that it is a Higgs boson from a more complex model, such as supersymmetry (a theory which says every elementary particle has a so-far unseen heavier partner)," another CMS researcher, John Conway, told Reuters.

In recent months, rumors have flown that the particle might be some sort of super-Higgs - "the link between our world and most of the matter in the universe" as predicted by U.S. physicist Sean Carroll in a new book.

But David Charlton, who speaks for the ATLAS team, said the latest analysis, presented on Thursday to a conference in the Italian Alps, pointed to the particle fitting the Standard Model - which would exclude exotica.

However, CERN scientists agree nothing startlingly new could be expected until much later in the decade, well after the LHC - shut down last month for two years to allow its power and reach to be doubled - resumes operations in early 2015.

In the giant subterranean collider, which started up in March 2010, particles are smashed together hundreds of times a second at near the speed of light to simulate the Big Bang. The debris is then tracked on huge detectors.

But the new particle turns up only once in every trillion collisions - leaving the thousands of physicists and analysts at CERN, and in laboratories around the world, the massive task of deciding what data to discard.

Job seekers stand in line to meet with prospective employers at a career fair in New York City, October 24, 2012.

WASHINGTON | Thu Jan 17, 2013 4:58pm EST

WASHINGTON (Reuters) - The number of Americans filing new claims for unemployment aid hit a five-year low last week and residential construction surged in December, the latest signs that the U.S. economic recovery remains on track.

The reports on Thursday showed the economy was weathering an uncertain fiscal environment surprisingly well. Still, growth in the fourth quarter was likely subdued with only a modest pick-up expected in the first three months of this year.

"While growth has been slow, the damage done from the uncertainty surrounding the fiscal cliff was not sufficient to topple the recovery," said Millan Mulraine, a senior economist at TD Securities in New York.

The fiscal cliff refers to a wave of deep government spending cuts and tax increases, part of which was avoided after a last-minute agreement by U.S. lawmakers. A fight over raising the government's borrowing limit looms.

Initial claims for state unemployment benefits fell 37,000 to a seasonally adjusted 335,000, the lowest level since January 2008, the Labor Department said. It was the largest weekly drop since February 2010 and ended four straight weeks of increases.

While problems adjusting the data for seasonal fluctuations might have exaggerated the decline, economists said the report still suggested an improvement in sluggish labor market conditions and the economy as a whole.

"Having taken a pinch of salt, however, we would suggest that the trend in claims generally show no pickup in layoff activity around the turn of the year," said John Ryding, chief economist at RDQ Economics in New York.

A separate report from the Commerce Department showed housing starts jumped 12.1 percent last month to their highest level since June 2008. Permits for future home construction were also the highest in about 4-1/2 years.

Stocks on Wall Street ended higher on the fairly upbeat jobs and housing data, with the broad Standard & Poor's 500 index hitting a five-year high. Commodity prices also firmed, but U.S. government bond prices slumped.

The dollar rallied to a 2-1/2-year high against the yen.

HOUSING GAINING TRACTION

Though warm weather likely helped, the data was confirmation of the improving housing market tone, and home building made gains across all four regions. Groundbreaking also increased for both single-family homes and multi-family units.

Builders started 780,000 houses in 2012. While still low by historical standards, it was the third straight year of gains in home construction. Housing is no longer a drag on the economy and residential construction is expected to have contributed to growth last year for the first time since 2005.

"The housing recovery has steam. Interest rates are rock-bottom low, inventories of new and existing homes are lean, and the economy is creating jobs," said Patrick Newport, an economist at IHS Global Insight in Lexington, Massachusetts.

Newport said they expected starts to rise to 970,000 this year. The reports came on the heels of data this week showing solid retail sales and manufacturing growth in December.

But weak exports, a slow pace of inventory accumulation and the reversal of a surge in defense spending probably slowed growth to below a 2 percent annual pace in the fourth quarter.

In a reminder that the outlook for the economy remained shaky, a third report showed factory activity in the U.S. mid-Atlantic region contracted this month as new orders tumbled.

The Philadelphia Federal Reserve Bank said its business activity index fell to -5.8 from 4.6 in December. A reading below zero indicates contraction in manufacturing in eastern Pennsylvania, southern New Jersey and Delaware.

"Manufacturing has slowed but it's still growing. I'm not going to read too much into this until I see other regional surveys," said Gus Faucher, a senior economist at PNC Financial Services in Pittsburgh.

The claims data covered the survey week for the January data for the closely watched nonfarm payrolls report. The four-week moving average of new jobless claims, a better measure of labor market trends, fell 6,750 to 359,250, suggesting some improvement in labor market conditions.

Job growth has been gradual, with employers adding 155,000 new positions in December. The unemployment rate held steady at 7.8 percent last month. High jobless is likely to keep the Federal Reserve on an expansionary monetary policy path.

Atlanta Fed President Dennis Lockhart said on Thursday the Federal Reserve will very likely need to continue its large-scale asset purchases into the second half of this year.

WASHINGTON | Thu Jan 31, 2013 11:32am EST

WASHINGTON (Reuters) - The Chesapeake Bay, North America's biggest estuary, is still ailing but making some progress as it struggles to recover from over-fishing and pollution, a partnership overseeing its revival said on Thursday.

The number of juvenile crabs is the highest in two decades, rockfish are stable and last year's "dead zone," the part of the bay without enough oxygen to support life, seems to be the smallest since 1985, the Chesapeake Bay Program said in its 2011-12 "Bay Barometer."

On the down side, water clarity was very poor and only a third of the bay met standards for dissolved oxygen, a measure of water's health. The oyster population also was at less than 1 percent of historic levels.

"While we clearly have a lot of work to do, the bay is resilient and we have reason for hope," Nick DiPasquale, director of the federal and state program, said in a statement.

The Chesapeake Bay, home to more than 3,600 species of plants and animals, has been fouled by decades of over-fishing and pollution. Pollutants include sediment, manure, trash and chemicals that flow into it from its 64,000-square-mile (166,000-square-km) watershed across six states.

The Chesapeake Bay Program was formed in 1983 to restore the estuary, where salt water from the ocean mixes with fresh water. It includes Maryland, Pennsylvania, Virginia, the District of Columbia, the Environmental Protection Agency and citizens groups.

The group said that most of the bay's feeder freshwater streams were in poor or very poor condition. Water murkiness and algae levels in 2011 were the worst since 2009.

But the big Susquehanna Flats grass bed survived Tropical Storm Lee in 2011. In another sign of health, grasses in the middle of the Chesapeake showed "dramatic increases," the program said.

The adult female crab population was still within the sustainable range in 2012 despite falling for two years.

Nitrogen and phosphorus, components in fertilizers that contribute to algae growth, each moved about 20 percent closer to their targets from July 2009 to June 2011 under a bay "pollution diet."

Sediment was about 30 percent nearer its target, helped by more forested buffers being planted to limit runoff into streams and rivers.

In a separate report, the U.S. Geological Survey said this month that nutrient and sediment trends at nine bay monitoring sites had shown an overall lack of improvement through 2010.

Ohio Governor John Kasich speaks during the CERAWEEK world petrochemical conference in Houston March 7, 2012.

COLUMBUS, Ohio | Thu Dec 20, 2012 6:36pm EST

COLUMBUS, Ohio (Reuters) - Ohio's Republican Governor Johns Kasich on Thursday signed into law a measure that would slightly weaken the state's law on carrying concealed weapons, less than a week after a Connecticut school massacre focused national attention on gun control.

The bill would require Ohio residents demonstrate competency with the weapon only once rather than each time the concealed carry permit expires. It also would allow carrying concealed weapons in the parking garage of the State Capitol.

Kasich signed the bill along with 41 others and did not hold a signing ceremony. A press release summarizing his actions put the gun law near the bottom of list of those signed.

Kasich foreshadowed the action earlier in the week, telling reporters he would sign it: "Whatever we do, we don't want to erode the Second Amendment rights of law abiding citizens."

The Second Amendment to the U.S. Constitution gives American citizens the right to bear arms.

Democratic state Representative Tracy Maxwell Heard said Kasich should not have signed such a "divisive" bill less than a week after a national tragedy.

"Rather than rushing to sign legislation that weakens our gun laws, we must use this time for a full, inclusive reflection," Maxwell Heard said.

Last Friday, a gunman opened fire at an elementary school in Newtown, Connecticut, killing 20 children and six adults before shooting himself.

Michigan's Republican Governor Rick Snyder on Tuesday vetoed a proposed law that would have allowed some gun owners to bring concealed weapons into public places such as schools. Snyder said that the Connecticut shooting had influenced his decision.
