Leading light in science, Italy's 'lady of the stars' Hack dies

ROME | Sat Jun 29, 2013 11:51am EDT

ROME (Reuters) - Astrophysicist Margherita Hack, a popular science writer, public intellectual and the first woman to lead an astronomical observatory in Italy, died on Saturday at the age of 91.

Known as the "lady of the stars", Hack's research contributed to the spectral classification of many groups of stars, and the asteroid 8558 Hack is named after her.

She introduced astrophysics to a broad Italian audience, from university textbooks to colorful tomes of astronomy for children, and was astronomy chair at the University of Trieste and director of the Trieste Astronomical Observatory from 1964 to 1987, the first woman to hold the position.

Hack was one of Italy's most visible scientists over her career and remained a grey-haired media presence into her 90s, often consulted for her assessment of the issues of the day from a wooden rocking chair in her book-lined Trieste home.

An outspoken atheist in a predominantly Catholic country, Hack was known for her opposition to the influence of religious beliefs over scientific research, and lobbied for legalized abortion, euthanasia, animal protection and gay rights.

One of her many books, "Why I am Vegetarian", published at the age of 89, outlined Hack's belief that there was no difference between human and animal pain and that eating meat damaged the environment, sparking debate in a country with a proud tradition of meatballs, beef pasta dishes and cured hams.

In December 2012 she told a reporter she had decided not to have a heart operation that could prolong her life, wryly commenting that she might as well save the Italian public health service the money, and saying she preferred to stay at home with her books and her husband of seven decades, Aldo De Rosa.

"I do not believe in the afterlife," she said, chuckling and animated, in her final television appearance in March. "When I die my particles will flutter about the terrestrial atmosphere."

CAPE CANAVERAL, Florida | Fri Jun 28, 2013 5:24pm EDT

CAPE CANAVERAL, Florida (Reuters) - NASA has selected Space Florida, a state-backed economic development agency, to take over operations, maintenance and development of the space shuttle's idled landing site at the Kennedy Space Center in Florida, officials said on Friday.

Terms of the agreement, which have not yet been finalized, were not disclosed, but Space Florida has made no secret about its desire to take over facilities no longer needed by NASA to develop a multi-user commercial spaceport, somewhat akin to an airport or seaport.

The state already has a lease for one of the space shuttle's processing hangars, and an agreement with Boeing to use the refurbished facility for its planned commercial space taxi.

The so-called CST-100 is one of three spaceships under development in partnership with NASA to fly astronauts to the International Space Station, a permanently staffed, $100 billion research outpost that flies about 250 miles above Earth.

NASA ended its 30-year space shuttle program in 2011, leaving Russia's Soyuz capsules as the sole means to transport crews to the station, a service that costs the United States more than $70 million per person. NASA hopes to buy rides commercially from a U.S. company by 2017.

The shuttle's retirement left the Kennedy Space Center loaded with equipment and facilities that are not needed in NASA's new human space initiative, which includes a heavy-lift rocket and deep-space capsule for journeys to asteroids, the moon and other destinations beyond the space station's orbit.

Last year, NASA solicited proposals for agencies or companies to take over the shuttle landing facility and its 15,000-foot (4,572-meter) runway, one of the longest in the world.

Additional landing site infrastructure includes an aircraft parking ramp measuring 480 by 550 feet, a landing aids control building, a 90-foot (27-meter) wide shuttle tow way, an air traffic control tower and a 23,000-square-foot (2,137-square-meter) enclosure used by convoy vehicles that serviced the shuttles after landing.

In addition to shuttles returning from orbit, the runway is used by heavy transport aircraft, military cargo planes, T-38, Gulfstream G-2 and F-104 aircraft, and helicopters.

Space Florida would like that list to also include suborbital passenger ships, such as the two-seater Lynx space plane being developed by privately owned XCOR Aerospace, orbital vehicles like Microsoft co-founder Paul Allen's air-launched Stratolaunch Systems, and unmanned aircraft.

"We look forward to working with NASA and KSC leadership in the coming months to finalize the details of this transaction in a way that will provide the greatest benefit to incoming commercial aerospace businesses," Space Florida President Frank DiBello said in a statement.

Turning the shuttle landing facility over to a commercial operator will save NASA more than $2 million a year in operations and maintenance costs, documents posted on the agency's procurement website show.

The landing facility also includes a 50,000-square-foot (4,645-square-meter) hangar that Space Florida already owns. A commercial flight services company, Starfighters Aerospace, currently operates there.

NASA said it received five bids for the shuttle landing facility, including the winning one.

The announcement that Space Florida had been chosen was made by NASA administrator Charles Bolden who was in Florida for the opening of the shuttle Atlantis exhibit at the Kennedy Space Center Visitor Complex.

Proposals to take over one of the shuttle's two launch pads are due on July 5.

CAPE CANAVERAL, Florida | Thu Jun 27, 2013 11:00pm EDT

CAPE CANAVERAL, Florida (Reuters) - A small NASA telescope was poised for launch on Thursday on a mission to determine how the sun heats its atmosphere to millions of degrees, sending off rivers of particles that define the boundaries of the solar system.

The study is far from academic. Solar activity directly impacts Earth's climate and the space environment beyond the planet's atmosphere. Solar storms can knock out power grids, disrupt radio signals and interfere with communications, navigation and other satellites in orbit.

"We live in a very complex society and the sun has a role to play in it," said physicist Alan Title, with Lockheed Martin Space Systems Advanced Technology Center in Palo Alto, California, which designed and built the telescope.

Scientists have been trying to unravel the mechanisms that drive the sun for decades but one fundamental mystery endures: How it manages to release energy from its relatively cool, 10,000 degree Fahrenheit (5,500 degree Celsius) surface into an atmosphere that can reach up to 5 million degrees Fahrenheit (2.8 million Celsius).

At its core, the sun is essentially a giant fusion engine that melds hydrogen atoms into helium. As expected, temperatures cool as energy travels outward through the layers. But then in the lower atmosphere, known as the chromosphere, temperatures heat up again.

Pictures and data relayed by the Interface Region Imaging Spectrograph, or IRIS, telescope may finally provide some answers about how that happens.

The 4-foot (1.2-meter) long, 450-pound (204-kg) observatory will be observing the sun from a vantage point about 400 miles above Earth. It is designed to capture detailed images of light moving from the sun's surface, known as the photosphere, into the chromosphere. Temperatures peak in the sun's outer atmosphere, the corona.

All that energy fuels a continuous release of charged particles from the sun into what is known as the solar wind, a pressure bubble that fills and defines the boundaries of the solar system.

"Every time we look at the sun in more detail, it opens up a new window for us," said Jeffrey Newmark, IRIS program scientist at NASA headquarters in Washington, D.C.

The telescope is scheduled to be launched aboard an Orbital Sciences Corp Pegasus rocket on Thursday at 10:27 p.m. EDT (0227 GMT Saturday). Pegasus is an air-launched system that is carried aloft by a modified L-1011 aircraft that will take off from Vandenberg Air Force Base in California about 55 minutes before the scheduled launch.

The rocket is released from the belly of the plane at an altitude of about 39,000 feet so it can ignite and carry the telescope into orbit.

IRIS, which cost about $145 million including the launch service, is designed to last for two years.

NASA probe finds new zone at doorstep to interstellar space
Jun 27th 2013, 21:52

By Irene Klotz

CAPE CANAVERAL, Florida | Thu Jun 27, 2013 5:52pm EDT

CAPE CANAVERAL, Florida (Reuters) - Reports last summer than NASA's long-lived Voyager 1 space probe had finally left the solar system turned out to be a bit premature, scientists said on Thursday.

Rather, the spacecraft, which was launched in 1977 for a five-year mission to study Jupiter and Saturn, has found itself in a previously unknown region between the outermost part of the solar system and interstellar space.

It is an unusual and unexpected thoroughfare, a place where charged particles from the sun have virtually disappeared and those coming from galactic cosmic rays beyond the solar system are plentiful.

By that measure alone, scientists initially thought Voyager 1 did indeed finally reach interstellar space on August 25, 2012, becoming the first man-made object to leave the solar system.

But one key measurement killed that theory. The magnetic field in which Voyager 1 traveled was still aligned like the sun's. If the probe were truly in interstellar space, scientists expect that the direction of the magnetic field would be different.

"You can never exclude a really peculiar coincidence, but this was very strong evidence that we're still in the heliosheath" - the bubble of plasma from the sun that surrounds the solar system, said Voyager scientist Leonard Burlaga, with NASA's Goddard Space Fight Center in Greenbelt, Maryland.

Additional measurements later turned up a second odd reading. The cosmic ray particles were not uniformly distributed around Voyager 1 like scientists expected them to be in interstellar space. Instead, the charged particles, which stem from distant supernova explosions, were oriented in particular directions.

That led scientists to conclude that Voyager 1 was in some sort of magnetic boundary zone, where particles from inside and outside the solar system could easily swap places, but where the sun's influence still reigns supreme.

"We have no explanation for why we even found this new region," Burlaga told Reuters.

So far, Voyager's sister probe, Voyager 2, which is exiting the solar system in a different direction, has not encountered the same phenomena - nor may it ever.

"Voyager 2 has seen exactly what the models predicted we would see, unlike Voyager 1, which didn't," said lead scientist Ed Stone, with the California Institute of Technology in Pasadena, California.

Voyager 1 may be in an unusual place where the heliosheath and interstellar space connect, he added.

Voyager 1 is now about 11 billion miles (18 billion km) from Earth. At that distance, it takes radio signals, which move at the speed of light, 17 hours to make a one-way trip to Earth.

Scientists do not know how much farther Voyager has to travel to reach interstellar space. The spacecraft, which is powered by the slow decay of radioactive plutonium, will begin running out of energy for its science instruments in 2020. By 2025, it will be completely out of power.

The research appears in the journal Science this week.

Scientists make wire of carbon, may sometime rival copper
Jun 26th 2013, 23:09

By Environment Correspondent Alister Doyle

OSLO | Wed Jun 26, 2013 7:09pm EDT

OSLO (Reuters) - Scientists have made a strong, lightweight wire from carbon that might eventually be a rival to copper if its ability to conduct electricity can be improved, Cambridge University said on Thursday.

They said it was the first time that the super-strong carbon wires, spun in a tiny furnace that looks like a candy floss machine with temperatures above 1,000 degrees Celsius (1,800 F), had been made "in a usable form" a millimeter (0.04 inch) thick.

Krzysztof Koziol of the University's department of materials science and metallurgy told Reuters in a telephone interview that commercial applications were still years away but that "our target is to beat copper".

Wire made in the laboratory from carbon nanotubes (CNTs) - microscopic hollow cylinders composed of carbon atoms - is 10 times lighter than copper and 30 times stronger, the university said in a statement.

Among advances, the scientists found a way to solder CNTs to metal, something that had previously not been possible.

A big drawback for CNTs is that a kg (2.2 lbs) of copper is 2.5 times more conductive than a kg of CNT.

For the next few years, Cambridge University would focus on copper and CNT hybrids, a programme to create "ultra-conductive" copper that is supported by the copper industry. In some blends, tiny amounts of carbon improve copper's conductivity.

The International Copper Association, representing producers of more than half the world's copper, said that mass production of ultra-conductive copper could be 10 years away if the science can be improved.

But development of pure high-conductive CNT carbon that could supplant the metal in wiring is a remote prospect, said Malcolm Burwell, the Association's director of technology in North America.

"It's a long way off. The industry doesn't stay awake at night worrying" about carbon nanotubes supplanting copper, he said. He said 60 percent of all copper sold worldwide was to carry electricity.

Koziol, however, said pure CNT wires could have more immediate uses because they are more flexible than copper. That could be valuable in moving parts such as robot arms or in planes or cars where flexibility is more important than conductivity.

Weight can be crucial. About a third of the weight of a large space satellite, weighing 15 tones, is typically copper. A Boeing 747 jumbo jet uses as much as 215 km (135 miles) of copper wiring, weighing more than 2 tones, the university said.

The UK National Grid said a benefit of CNTs, if developed at commercial scale at a competitive cost, was that they can operate at high temperatures.

"A potential application ... is the ability to produce a conductor that operates effectively at high temperatures, reducing fatigue on our assets and extending the useful life of the conductor," spokeswoman Gillian West said.

"CNT may also be beneficial as it is lightweight and so much easier to transport to our sites," she said.

Scientists find neighbor star with three planets in life-friendly orbits
Jun 26th 2013, 00:27

By Irene Klotz

CAPE CANAVERAL, Florida | Tue Jun 25, 2013 8:27pm EDT

CAPE CANAVERAL, Florida (Reuters) - A neighbor star has at least six planets in orbit, including three circling at the right distance for water to exist, a condition believed to be necessary for life, scientists said on Tuesday.

Previously, the star known as Gliese 667C was found to be hosting three planets, one of which was located in its so-called "habitable zone" where temperatures could support liquid surface water. That planet and two newly found sibling worlds are bigger than Earth, but smaller than Neptune.

"This is the first time that three such planets have been spotted orbiting in this zone in the same system," astronomer Paul Butler, with the Carnegie Institution in Washington, D.C., said in a statement.

Scientists say the discovery of three planets in a star's habitable zone raises the odds of finding Earth-like worlds where conditions might have been suitable for life to evolve.

"Instead of looking at 10 stars to look for a single potentially habitable planet, we now know we can look at just one star and have a high chance of finding several of them," astronomer Rory Barnes, with the University of Washington, said in a statement.

Additional observations of Gliese 667C and a reanalysis of existing data showed it hosts at least six, and possibly, seven planets.

The star is located relatively close to Earth, just 22 light years (129 trillion miles/207 trillion km) away. It is about one-third the size of the sun and the faintest star of a triple star system.

In addition to the three well-positioned "super-Earths," two more planets may orbit on the fringe of the star's habitable zone and also could possibly support life.

The research will be published this week in the journal Astronomy & Astrophysics.

LONDON | Sun Jun 23, 2013 12:09am EDT

LONDON (Reuters) - Plants do complex arithmetic calculations to make sure they have enough food to get them through the night, new research published in journal eLife shows.

Scientists at Britain's John Innes Centre said plants adjust their rate of starch consumption to prevent starvation during the night when they are unable to feed themselves with energy from the sun.

They can even compensate for an unexpected early night.

"This is the first concrete example in a fundamental biological process of such a sophisticated arithmetic calculation," mathematical modeler Martin Howard of John Innes Centre (JIC) said.

During the night, mechanisms inside the leaf measure the size of the starch store and estimate the length of time until dawn. Information about time comes from an internal clock, similar to the human body clock.

"The capacity to perform arithmetic calculation is vital for plant growth and productivity," JIC metabolic biologist Alison Smith said.

"Understanding how plants continue to grow in the dark could help unlock new ways to boost crop yield."

New shuttle Atlantis exhibit gives close-up look at space flight
Jun 22nd 2013, 17:05

By Irene Klotz

CAPE CANAVERAL, Florida | Sat Jun 22, 2013 1:05pm EDT

CAPE CANAVERAL, Florida (Reuters) - In deciding how to exhibit the space shuttle Atlantis, which goes on display next week, the Kennedy Space Center Visitor Complex in Florida opted for a perspective that would allow the public a rare view.

"One of the ideas that developed very early was to show the orbiter as only astronauts had seen it - in space," said Bill Moore, chief operating officer with Delaware North Companies Parks and Resorts, which operates the visitors center for NASA at Cape Canaveral.

The developers of the exhibit raised the 150,000-pound (68,000-kg) spaceship 30 feet into the air and tilted it 43 degrees over on its left side, simulating the vehicle in flight.

The shuttle's 60-foot-long cargo bay doors were also opened, a gutsy move since the 2.5-ton panels were designed for the weightless environment of space, and a mock-up robotic arm was added - the real one could not support its weight in Earth's gravity.

Then a viewing ramp was built to bring visitors almost within arm's reach of the ship that flew NASA's 135th and final shuttle mission in 2011, closing a 30-year chapter in U.S. space history.

"About half our country now is past the age of being around when we walked on the moon," Moore said. "We want to keep a balance between telling the history of how we got here and inspiring people for what the future of space is all about."

The shuttle is accompanied by a high-fidelity mockup of the Hubble Space Telescope. The real telescope's 1990 launch, its repair three years later and four life-extending servicing missions comprise one of the shuttle program's success stories.

Positioned throughout the 90,000-square-foot (8,361-square-meter) building housing Atlantis are interactive exhibits, shuttle hardware, films and other displays that include darker tales, including the shuttle's tortured 12-year development program and the two ships lost in accidents that claimed 14 lives.

"You have to talk about all five shuttles, you can't talk about just three," Moore said. "We don't hide behind those facts. We don't not talk about them."

Before arriving at the Atlantis exhibit, visitors are routed beneath an eye-popping, full-size replica shuttle external fuel tank and twin rocket boosters. The stack stretches 184 feet into the sky.

Atlantis followed sister ships Discovery and Endeavour into retirement. They, along with the prototype Enterprise, which was used for atmospheric testing before the shuttle's 1981 debut, now draw huge crowds to their respective museums.

Discovery is at the Smithsonian National Air and Space Museum's Udvar-Hazy Center in Chantilly, Va.; Endeavour is at the California Science Center in Los Angeles; and Enterprise is at the Intrepid Sea-Air Space Museum in New York.

All 135 shuttle missions were launched from the Kennedy Space Center, which also housed and prepared the ships and their cargo for flight.

The new $100-million Atlantis facility is focused on three main themes. The first is about the engineering and operation of the shuttle, a machine comprising more than 2.5 million hand-made parts.

The second is about the thousands of people who worked on the program over more than 30 years, while the last has to do with the future, perhaps the most challenging part of the exhibit.

NASA is working on a new capsule and rocket to carry astronauts to destinations beyond the International Space Station, a permanently staffed, $100-billion research outpost that flies about 250 miles in space.

The station was pieced together by U.S. space shuttle crews over more than a decade.

But where that rocket and capsule will go and when it will arrive is an ongoing debate. Meanwhile, NASA is hoping to buy rides for its space station crews from private industry by 2017.

The exhibit opens June 29. Ticket prices are $50 for adults and $40 for children aged 3-11, plus tax.

Europe tests reusable spaceship

PARIS | Fri Jun 21, 2013 12:20pm EDT

PARIS (Reuters) - The European Space Agency is preparing to launch an experimental reusable spaceship next summer following a successful atmospheric test flight this week, officials said at the Paris Airshow.

A mock-up built by Thales Alenia Space was dropped from a helicopter flying 1.9 miles above the Mediterranean near Sardinia on Wednesday to check its handling and parachute system, company officials said.

The 14.4 foot long (4.4 meter) craft, known as "IXV" as it is an intermediate experimental vehicle, splashed down in the ocean and was retrieved by an awaiting ship.

The test flight clears IXV for a follow-on demonstration run beyond the Earth's atmosphere in August next year. That program, in turn, paves the way for an orbital prototype dubbed "Pride", slated to launch in 2018.

The aim is to help Europe develop an autonomous atmospheric re-entry system that could be used on vehicles flying experiments in space, Roberto Provera, director of space transportation programs for Thales Alenia Space, told Reuters.

"It's the first time in Europe that we've tried something like this," Provera said, adding that it could eventually be used to carry people.

The vehicles are similar to but smaller than the U.S. military's X-37B Orbital Test Vehicles, built by Boeing. Like NASA's now-retired space shuttles, they have "lifting body" designs shaped to produce lift without airplane-like wings.

For its next test, Europe will launch another IXV vehicle on a Vega rocket from the Guiana Space Center in French Guiana.

Once at an altitude of about 199 miles, the IXV will separate from the rocket and climb to about 267 miles before slamming back into the atmosphere at a speed of about 4.7 miles per second and parachuting into the Pacific Ocean.

Several U.S. firms are also developing reusable spaceships. Designs include traditional capsules, as well as "lifting body" vehicles.

SPACE STATION

Privately owned Sierra Nevada Corp., for example, is testing a vehicle called Dream Chaser that has NASA backing.

The U.S. space agency, which retired its space shuttles in 2011, is seeking commercial options to fly astronauts to the International Space Station, a permanently staffed research outpost that flies about 250 miles above Earth.

Virgin Galactic, a U.S. offshoot of billionaire Richard Branson's London-based Virgin Group, is testing a suborbital passenger vehicle called SpaceShipTwo, expected to start flying next year.

The U.S. military has two experimental unmanned reusable spaceships developed under its X-37B program. One is in orbit.

President Vladimir Putin told astronauts in orbit in April that Russia would send up the first manned flights from its own soil in 2018, using a new launch pad he said would help the once-pioneering space power explore deep space and the moon.

Thales Alenia said it has not yet finalized a price for Pride with the European Space Agency, but expects it will cost about the same as the IXV program, or roughly 200 million Euros ($264 million).

Thales Alenia Space is a joint venture owned 67 percent by France's Thales and 33 percent by Italy's Finmeccanica.

Asteroid-mining firm meets $1 million crowd-funding goal

Thu Jun 20, 2013 7:52pm EDT

(Reuters) - A start-up asteroid mining firm that launched a crowd-funding campaign to gauge interest in a planned space telescope reached its $1 million goal, company officials said on Thursday.

Bellevue, Washington-based Planetary Resources intends to build and operate telescopes to hunt for asteroids orbiting near Earth and robotic spacecraft to mine them.

The company, whose financial backers include Google's founders, also envisions a companion educational and outreach program to let students, museums and armchair astronomers make use of the first telescrope that Planetary Resources plans to build, called Arkyd.

Three weeks ago, Planetary Resources launched a crowd-funding initiative on Kickstarter to assess interest in the project and set a goal of raising $1 million by June 30.

"It surpassed that amount Wednesday night," company spokeswoman Stacey Tearne wrote in an email.

"We currently have 12,000-plus backers who have pledged just over $1.07 million," Tearne said.

For a pledge of $25, participants can make use of a "space photo booth," by sending a picture to be displayed on the telescope so a remote camera can snap an image, with Earth in the background, and transmit it back.

For $200, participants can actually use the telescope to look at an astronomical object.

The Kickstarter campaign complements the company's ongoing efforts to design and build Arkyd. Investors include Google executives Larry Page and Eric Schmidt, as well as Ross Perot Jr., chairman of the real estate development firm Hillwood and The Perot Group.

PARIS | Wed Jun 19, 2013 2:06pm EDT

PARIS (Reuters) - The European Space Agency signed final contracts with Thales Alenia Space Italy for work on a pair of missions to assess if the planet Mars has or ever had life, officials said at the Paris Airshow this week.

Until last year, the ExoMars program was a joint project between ESA and the U.S. space agency NASA. But NASA dropped out, citing budget problems.

The Russian space agency Roscosmos stepped in to provide two Proton rockets to send an orbiting atmospheric probe and test lander to Mars in January 2016, and a follow-on rover in August 2018 that will drill below the planet's surface to look for spores and bacteria.

Roscosmos also is providing a landing system for the rover and scientific instruments.

"It took some time, some energy, some efforts from a lot of different parties. It was not easy to move from an ESA-NASA cooperation to an ESA-Roscosmos cooperation," Jean-Jacques Dordain, head of ESA, told reporters after signing a 230 million euros ($300 million) contract with Thales Alenia.

Thales Alenia, selected as the ExoMars prime contractor five years ago, plans to spend 146 million euros on the 2016 orbiter and lander. The satellite is being designed to search the thin Martian atmosphere for telltale gases associated with biological activity. It also will serve as the key communications relay for the 2018 rover.

The lander primarily is intended to test the technologies needed to touch down on Mars, a notoriously difficult task that has bedeviled nearly all of Russia's previous efforts and has given NASA trouble as well. The United States currently has two operational rovers on Mars, Curiosity and Opportunity.

After pulling out of the ExoMars program, NASA said it would send a second Curiosity-type rover to Mars in 2020.

The rest of the ExoMars budget will be spent on the 2018 rover, a mission that will make the first direct search for life since NASA's 1970s-era Viking landers.

Instead of sampling the planet's radiation-blasted surface as the Viking probes did, the ExoMars rover will use a radar sounder to search for subterranean water and then drill down about 6 feet for samples that will be processed through onboard laboratories.

"If there is any life and if we discover it, it will be unambiguous," said Vincenzo Giorgo, Thales Alenia's vice president of exploration and space. "On Viking everybody thought, รข€˜We found it, we found it,' but then nobody could prove it."

Thales Alenia Space is a joint venture owned 67 percent by France's Thales and 33 percent by Italy's Finmeccanica.

Beetles, housefly larvae open new frontier in animal feed sector
Jun 19th 2013, 14:03

By Axelle du Crest and Valerie Parent

PARIS | Wed Jun 19, 2013 10:03am EDT

PARIS (Reuters) - French start-up company Ynsect has identified a cheap, nourishing and locally sourced alternative to soybeans as a vital source of protein in animal feed. The clue is in its name.

Ynsect is not alone in looking to invertebrates to meet a jump in demand for meat and fish, and so for feed, in coming decades.

Black soldier flies, common housefly larvae, silkworms and yellow mealworms were named as among the most promising species for industrial feed output in a report last month by the FAO, the United Nations food agency.

"Given insects' natural role as food for a number of farmed livestock species, it is worth reconsidering their role as feed for specific poultry and fish species," the Food and Agriculture Organization's report said.

Jean-Gabriel Levon, co-founder of Ynsect, said new protein sources were essential in a market where costs are set to climb.

"Insects are an interesting source which can be bred locally," Levon said. "We are in the same situation as oil, with resources getting scarcer and more expensive."

According to the FAO, protein such as meat meal, fishmeal and soymeal make up 60 to 70 percent of the price of feed.

Soybean prices have more than doubled over the past decade due to soaring demand and fishmeal prices have also jumped.

The 2-year old company has been developing an insect-based meal that could make up 5-30 percent of feed products, Levon said.

Ynsect, which has around 10 rivals globally, is now raising funds to build the first European insect meal production unit by 2014-2015. One well-heated part of the plant would breed insects and the other would crush them into powder.

It aims to focus on using flies and beetles and Levon says a great advantage is that they can eat just about anything - for example human food leftovers such as potato peelings.

Once crushed, co-products such as shells can be used in the pharmaceutical sector, for cosmetics and wastewater treatments.

GREAT FERTILISER

What is more, insect droppings make great fertilizer.

"Insects drink very little water. Their droppings are very dry. They're like sand and have all the qualities needed for a classic fertilizers," Levon said.

Stephane Radet, who heads France's animal feed industry lobby (SNIA) said he was cautious as the protein product would have to prove itself to feed makers and win public acceptance.

"For new material to enter the manufacturing chain, it has to meet four major criteria: safety, quality, competitiveness and acceptability in the food sector, processors and at the bottom of the chain, the consumer," Radet said.

While another pioneering company, South Africa's AgriProtein Technologies, is rearing house flies and using insect flour for cattle feed, this is not allowed in the European Union where the "mad cow" disease crisis of the late 1990s has led to caution over the use of processed animal proteins (PAPs).

PAPs, particularly when cattle were given bovine protein, were blamed for the bovine spongiform encephalopathy (BSE) outbreak.

The European Commission has approved the use of PAPs to feed fish from June 1, which includes insect meal. It may allow their use in pig and poultry feed from 2014, lifting a ban on animal by-products imposed during the BSE outbreak.

The EU imports about 70 percent of its protein-rich material for animal feed. According to European Feed Manufacturer's Federation Fefac, Europe's market for processed animal feed is worth around 45 billion euros ($60 billion) a year.

Ynsect aims to start with fish feed, where insect-based meal could replace increasingly scarce fishmeal and fishoil.

According to the FAO, fish farming is the fastest-growing animal food producing sector and will need to expand sustainably to keep up with increasing demand.

Trials on certain fish species showed that diets where up to 50 percent of fishmeal was replaced with grass hopper meal produced equally good results as fishmeal only, the FAO added.

A further step one day might be to rear insects for direct human consumption - the FAO said insects already feed more than 2 billion humans in Africa, Asia and South America.

But EU regulations do not allow this, more research is needed on issues such as allergies, and only a few daring restaurants in Europe are experimenting for curious clients.

"As for targetting the human food market, that is for some other time. Eating insects is a laugh, people may be curious, but as far as we are concerned that won't be happening for the time being," Levon said. ($1 = 0.7467 euros)
