Italy's govt seeks to open competition (AP)

MILAN ? The Italian government has approved hotly contested emergency measures to open competition in a wide-range of sectors aimed at boosting growth and making room for young people in the workforce.

The measures approved Friday are the second prong in Premier Mario Monti's efforts to protect Italy from sovereign debt crisis, following a euro30 billion ($39 billion) austerity package past in December.

The measures will allow more taxi licenses, permit pharmacists to discount some medicines, and allow gas stations operators to choose whom they buy fuel from.

Monti told a news conference that the greater competition will benefit Italy's highly rigid society.

Taxi drivers have been staging wild cat strikes for days against the proposed reforms.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.

MILAN (AP) ? The Italian government has approved the release of euro5.5 billion ($7.1 billion) from state coffers to fund strategic infrastructure projects.

A government statement said the funds approved Friday would pay for railway lines in the poorer south, public housing and school projects and environmental safety measures.

The money is on top of euro4.8 billion approved in December for highway projects and high-speed railways.

Premier Mario Monti has combined the economic development and infrastructure ministries to ensure strong coordination of projects that can promote economic growth.

The Cabinet meeting in Rome is expected to approve a liberalization program later Friday.

Analysis: Italy refunding ordeal looks a little less daunting (Reuters)

MILAN (Reuters) ? Italy's goal of refinancing some 90 billion euros of long-term debt by the end of April is beginning to look within reach after months when the weight of its debt burden looked likely to tip the euro zone even deeper into crisis.

In spite of this month's mass downgrade of most euro countries by credit rating agency Standard & Poor's, Madrid romped through a debt sale on Thursday with support from cheap ECB lending to banks and steady interest from domestic investors.

The same factors should also help Rome.

Saddled with a 1.9 trillion euro ($2.5 trillion) public debt, Italy is the euro zone's third largest economy and investors have long feared it may prove too big to bail.

The amount of debt it must refinance between February and April looked almost unmanageable in November after international investors fled Italian bonds, driving even the country's three-year borrowing costs to nearly 8 percent.

But a fall in short-term yields after Italian banks awash with cheap ECB funds snapped up domestic bonds at recent sales has improved the market picture for Italy, now rated among the lower investment grades at BBB+ by S&P, on a par with bailed-out fellow struggler Ireland.

"I am convinced Italy can and will make it," said Intesa SanPaolo fixed-income analyst Chiara Manenti. "Recent auctions tell us tensions eased slightly. Looking ahead, the return of a net demand also on medium- and long-term maturities and a stop to disinvestments from abroad are crucial for Italy," she said.

Much hinges on efforts to persuade investors to accept deep losses on Greek debt, key to avoiding an unruly default there.

"It certainly isn't our main scenario, but we can't assign a zero probability to the event of Italy being shut out of debt markets. In the short term there are risks relating to a possible Greek default," said Matteo Regesta, a strategist at BNP Paribas in London.

ECB SUPPORT

Italy itself came dangerously close to sliding towards default in late 2011 and has since been striving to regain market confidence under the leadership of a new technocratic government headed by former EU Commissioner Mario Monti.

Crucially, Italy can count on the support of the European Central Bank both through its bond buying program and an unprecedented liquidity boost. At a December 21 ECB tender of three-year funds, Italian banks took 116 billion euros, almost a quarter of the total.

This cheap funding, analysts say, has fuelled demand for short-term Italian and Spanish paper at recent auctions -- a trend which Rome plans to exploit. With more ECB cash up for grab at a February tender, Italian investors would have enough to fill up any void resulting from lack of foreign interest.

"Domestic investors are likely to continue to participate --and indeed are incentivized to do so in order to protect existing exposure," Citi analysts wrote in a report last week.

Italian investors held 54 percent of the country's 1.6 trillion euro bonds and bills in June, the Bank of Italy said. Analysts estimate this share may have risen towards 60 percent.

"Like many issuers, Italy is relying more and more on its domestic investor base," said Citi analyst Jamie Searle.

To better target retail demand at home, Italy will also start issuing directly to small investors through electronic platforms in the first quarter of 2012.

Maria Cannata, in charge of debt management at Italy's Treasury, said on Tuesday that a higher domestic debt ownership helps but that Italy's debt is too great to rely almost exclusively on local buyers.

WOOING FOREIGN BUYERS

Domestic investors make up the bulk of demand for Italian short-term debt but its sales of longer-term bonds must also target foreign buyers. PM Monti went to woo them in London this week.

Unlike short-term rates, longer-term yields have retreated only modestly. At around 6.40 percent, 10-year yields are two percentage points above three-year ones and not far from the 7 percent mark that has led other countries to seek bailouts.

"It is the 10-year sector where the battle for market access is likely to be won or lost, hence the particular importance of the end-month BTP auctions," Citi analysts said in their report.

Italy is due to sell five- and 10-year BTP bonds on January 30, at an auction that will settle on February 1, when nearly 26 billion euros of BTPs and about 10 billion euros in coupons mature.

Ten years is the longest maturity Italy has attempted to sell since offering an off-the-run 15-year bond in mid-October.

Maturities longer than 10 years fall outside the scope of the ECB's bond purchases, traders say, and these buys are key in indirectly supporting demand at Italian bond sales.

With virtually no bonds maturing in January, Italy has pre-funded some of its redemptions this month. Intesa estimates net issuance at auctions settled in January at up to 39 billion euros including next week's sales of Treasury bills, zero-coupon and inflation-linked bonds.

Cannata said on Tuesday Rome would certainly boost issues of short-term bills, commercial paper and bonds with a maturity of up to three years in the first part of the year.

Once past the February-April refinancing hump, which represents 45 percent of 2012 medium and long-term maturities, Italy would have minimal redemptions in May and June.

But significantly shortening Italy's debt average life of seven years would increase refinancing risks. S&P warned last week that this would weaken an important credit strength for Italy and the Treasury is well aware of the danger.

"Already in the second half of the year we will necessarily have to return to a more uniform distribution along the yield curve to (ensure) a shortening in the average life of the debt ... remains modest," Cannata said. ($1 = 0.7757 euros)

(AP) ? The Air Force has sent into space a satellite that is expected to improve communications with military drones in the Middle East and Southeast Asia.

Officials say a Delta 4 rocket carried the WGS 4 satellite from Cape Canaveral Air Force Station at 7:38 p.m. Thursday.

It's the fourth in a series of military satellites that have been put into place since 2007. The next one is expected to be ready to launch next year.

WGS stands for Wideband Global SATCOM. The satellites are replacing aging Defense Satellite Communications System spacecraft and have 10 times the speed and capacity of the older satellites.

Video: Snakes improve search-and-rescue robots

Thursday, January 19, 2012

Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it's restricted from tight spaces. It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but the majority require large amounts of energy and are prone to overheating. Georgia Tech researchers have designed a new machine by studying the locomotion of a certain type of flexible, efficient animal.

"By using their scales to control frictional properties, snakes are able to move large distances while exerting very little energy," said Hamid Marvi, a Mechanical Engineering Ph.D. candidate at Georgia Tech.

While studying and videotaping the movements of 20 different species at Zoo Atlanta, Marvi developed Scalybot 2, a robot that replicates rectilinear locomotion of snakes. He unveiled the robot this month at the Society for Integrative & Comparative Biology (SICB) annual meeting in Charleston, S.C.

"During rectilinear locomotion, a snake doesn't have to bend its body laterally to move," explained Marvi. "Snakes lift their ventral scales and pull themselves forward by sending a muscular traveling wave from head to tail. Rectilinear locomotion is very efficient and is especially useful for crawling within crevices, an invaluable benefit for search-and-rescue robots."

Scalybot 2 can automatically change the angle of its scales when it encounters different terrains and slopes. This adjustment allows the robot to either fight or generate friction. The two-link robot is controlled by a remote-controlled joystick and can move forward and backward using four motors.

"Snakes are highly maligned creatures," said Joe Mendelson, curator of herpetology at Zoo Atlanta. "I really like that Hamid's research is showing the public that snakes can help people."

Marvi's advisor is David Hu, an assistant professor in the Schools of Mechanical Engineering and Biology. Hu and his research team are primarily focused on animal locomotion. They've studied how dogs and other animals shake water off their bodies and how mosquitos fly through rainstorms.

This isn't the first time Hu's lab has looked at snake locomotion. Last summer the team developed Scalybot 1, a two-link climbing robot that replicates concertina locomotion. The push-and-pull, accordion-style movement features alternating scale activity.

Condoms are slowing HIV spread in South Africa

CONDOMS are to thank for falling HIV infection rates in South Africa.

So say Leigh Johnson at the University of Cape Town and colleagues. They fed data from 2000 to 2008 on the country's HIV rates, condom use and the number of people taking antiretroviral therapy (ARTs) - which reduce the chances of passing on the virus - into two computer models of viral transmission and prevalence.

Condom use accounted for the vast majority of the decline in HIV, with only up to 17 per cent due to the natural dynamics of the disease, and up to 10 per cent down to the use of ARTs (Journal of the Royal Society Interface, DOI: 10.1098/rsif.2011.0826).

David Wilson at the University of New South Wales in Sydney, Australia, says the results highlight that condoms are "the most effective" way to protect against HIV epidemics. Johnson emphasises that all prevention and treatment programmes should be intensified.

Climate Change Ripples Through Mountain Ecosystems (LiveScience.com)

Like dominoes given one nudge, climate change in the form of reduced winter snowfall on mountaintops has subtle but powerful cascading effects felt throughout entire ecosystems, a new study finds.

In the northern mountains of Arizona, elk spend their winters in lower elevations where there?s much less snow and the cold is less pronounced. But the decrease in high-elevation snowfall in the mountains over the last 25 years has allowed elk to forage in these areas throughout winter. Researchers found that the elks' year-round high-elevation browsing has decimated the density of seasonal woodsy plants, which, in turn, has impacted the populations of songbirds (animals you might expect would actually benefit from less snow).

By preventing elk from entering several study sites for six years, the researchers were able to reverse the multi-decadal decline in plant and bird populations in these locations.

"Ecologic communities are pretty complex. There are all these tight interactions going on," said study co-author Tom Martin, a wildlife researcher with the U.S. Geological Survey. "Perturbation from climate can affect those communities in many indirect ways and cause all of these ramifying effects." [Odd Effects of Climate Change]

Dramatic declines

The densities of seasonal woodsy plants, including aspen and maple trees, in the northern Arizona mountains have steadily declined over the last two decades. Martin and his colleague John Maron, a biologist at the University of Montana, hypothesized that this decline is primarily the result of one of two things: decreased soil water or increased exposure to hungry elk.

To find out, the researchers set up 25-acre enclosures around three drainages, or?vegetation-rich valleys created by snowmelt. By keeping the elk out, the enclosures essentially mimicked the effects of large snowfall.

The researchers found that plant populations in the enclosures rebounded to levels last seen in 1996 ? suppressing winter-browsing elk for six years effectively reversed 15 years of plant-density decline. Plant populations in nearby open drainages, however, did not improve over the six years.

Similarly, the populations of five key songbird species rebounded in enclosed drainages. "With more vegetation, there are more nesting areas, and it becomes harder for predators to find the nests," Martin told Livescience.

Since the populations of elk have also strongly declined over the last 11 years, the results show that the elks' new tendency to stick around over winter is ravaging the plant and bird communities. "It doesn't take very many animals to have a pretty large impact if they?re there year-round," Martin explained.

Conservation implications

Eric Post, a biologist at Pennsylvania State University who was not involved with the research, said that the study demonstrates how observational and experimental research can compliment each other. "Both are necessary to study climate change ecology," Post told LiveScience.

While impressed with the study, Post thinks that the researchers "didn't nail down the driving factor in the relationship between plant growth and bird abundance." It seems convincing that the architecture of the vegetation would provide the birds with more nesting opportunities, he said, but that theory doesn't take into account the effect of invertebrate (animals without a backbone) abundance. The winter elk may also be affecting the populations of local insects, which the birds eat.

Still, Post believes that the study has important implications for conservation. "If you are interested in the conservation of birds, you need to look at more than just the birds and the vegetation they are dependent on," Post said. "You need to look at the broader system of browsing animals."

Martin agrees, adding that by "recognizing that these things happen, we can target priority habitats for conservation."

The study was published online Jan. 10 in the journal Nature Climate Change.
