World’s Earliest Prosthetics: Egyptian Mummy’s Fake Toe

http://pagead2.googlesyndication.com/pagead/show_ads.js

Two artificial big toes – one found strapped to the mummified remains of an Egyptian woman – may be the world’s earliest functional prosthetic body parts, according to a study: the linen and plaster “Greville Chester toe,” which dates back past 600 BC; and the wood and leather “Cairo toe,” which was built between 950-710 BC.

A superbly preserved artificial big toe from the Cairo museum in Egypt was found in 2000 in a tomb near Luxor in the ancient necropolis of Thebes. Archaeologists speculated the 50- to 60-year-old woman the prosthesis came from might have lost her toe due to complications from diabetes.

 
The Greville Chester Great Toe also shows signs of wear, suggesting that it may have been worn by its owner in life and not simply attached to the foot during mummification for religious or ceremonial reasons. However, unlike the Cairo specimen, the Greville Chester Great Toe does not bend and so is likely to have been more cosmetic.
That would easily make it the most ancient replacement limb known, several centuries older that the Roman-era bronze-and-wood leg unearthed from a burial site near Capua, Italy.

Both replicas, which even look like toes, were tested on two volunteers who had lost their right big toes. Lead researcher Dr Jacky Finch, from the University of Manchester, carried out the tests in the Gait Laboratory at Salford University’s Centre for Rehabilitation and Human Performance Research. Sure enough, the false toes offered greater mobility and comfort. Said Manchester study leader Dr. Jacky Finch in a recent article in The Lancet:

To be classed as true prosthetic devices any replacement must satisfy several criteria. The material must withstand bodily forces so that it does not snap or crack with use. Proportion is important and the appearance must be sufficiently lifelike as to be acceptable to both the wearer and those around them. The stump must also be kept clean, so it must be easy to take on and off. But most importantly, it must assist walking. The big toe is thought to carry some 40% of the bodyweight and is responsible for forward propulsion although those without it can adapt well […]
My findings strongly suggest that both of these designs were capable of functioning as replacements for the lost toe and so could indeed be classed as prosthetic devices.
If that is the case then it would appear that the first glimmers of this branch of medicine should be firmly laid at the feet of the ancient Egyptians.

A three-part wood and leather artefact housed in the Egyptian Museum in Cairo, and the Greville Chester artificial toe on display in the British Museum, helped their toe-less owners walk like Egyptians.

156 Years from birth of Nikola Tesla

http://pagead2.googlesyndication.com/pagead/show_ads.js

Today, on the 156th anniversary of Tesla’s birth, you could ask Europeans who Nikola Tesla was and their eyes will light up as they comment on his remarkable inventions. Over 100 years ago, Nikola Tesla proved the energy establishment wrong by creating something the establishment believed was impossible: a motor driven by alternating current. Ask most Americans, however, who Tesla was, and you’ll often get a blank stare.

Nikola Tesla (10 July 1856 – 7 January 1943), American scientist of Serbian origin, gave his greatest contribution to science and technological progress of the world as the inventor of the rotating magnetic field and of the complete system of production and distribution of electrical energy (motors, generators) based on the use of alternate currents.

He was an important contributor to the birth of commercial electricity, and is best known for his many revolutionary developments in the field of electromagnetism in the late 19th and early 20th centuries. Tesla’s patents and theoretical work formed the basis of modern alternating current (AC) electric power systems, including the polyphase system of electrical distribution and the AC motor, which helped usher in the Second Industrial Revolution. His name was given to the SI unit for magnetic induction (“tesla”). Tesla also constructed the generators of high-frequency alternate currents and high-voltage coreless transformer known today as “Tesla Coil”.

Tesla reminded us that a windmill is one of the most efficient energy devices ever devised, and suspected we’d eventually be able to harness the sun’s rays in an efficient way. He also advocated utilizing the heat “in the earth, the water, or the air.”

He proposed, essentially, geothermal energy plants, one capturing the heat of the earth, the other floating on the ocean, using the temperature differential between the surface water temperature and the deeper water temperatures to drive turbines to generate electricity.

Born an ethnic Serb in the village of Smiljan, Croatian Military Frontier in Austrian Empire (today’s Croatia), he was a subject of the Austrian Empire by birth and later became an American citizen. He received his education in Austria i.e. Austro-Hungary: primary school at Smiljan and Gospic (1862-70), and secondary school (Realgymnasium) at Karlovac (1870-1873). From 1875 to 1878 studied at the Polytechnic at Graz, and in 1880 he enrolled in the studies of natural philosophy at the Charles’ University in Prague. After his demonstration of wireless communication through radio in 1894 and after being the victor in the “War of Currents”, he was widely respected as one of the greatest electrical engineers who worked in America. During this period, in the United States, Tesla’s fame rivaled that of any other inventor or scientist in history or popular culture, but because of his eccentric personality and his seemingly unbelievable and sometimes bizarre claims about possible scientific and technological developments, Tesla was ultimately ostracized and regarded as a mad scientist by many late in his life.

Not only did this gifted genius bring the world AC power and radio — the foundations of modern civilization — but he progressed far beyond in the latter half of his life; and the world is still playing catch-up, a century later. He is the well-deserved icon of the free energy movement, providing inspiration to thousands of researchers around the world, who labor to embody some of Tesla’s later work, with the vision of having devices that can harness the inexhaustible sources of energy available to us freely from the environment and cosmos.
Tesla spent his last years in the hotel “New Yorker” in New York, where he died on January 7, 1943.

As Tesla said at his famous lecture in 1891, “We are whirling through endless space with an inconceivable speed; all around us, everything is spinning, everything is moving, everywhere is energy. There must be some way of availing ourselves of this energy more directly.”
“Then, with the light obtained from the medium, with the power derived from it, with every form of energy obtained without effort, from the store forever inexhaustible, humanity will advance with great strides. The mere contemplation of these magnificent possibilities expands our minds, strengthens our hopes and fills our hearts with supreme delight.”

Happy 156th Birthday, Nikola Tesla.

Titan: Nasa scientists discover evidence ‘that alien life exists on Saturn’s moon’

Researchers at the space agency believe they have discovered vital clues that appeared to indicate that primitive aliens could be living on the planet. Data from Nasa’s Cassini probe has analysed the complex chemistry on the surface of Titan, which experts say is the only moon around the planet to have a dense atmosphere.

They have discovered that life forms have been breathing in the planet’s atmosphere and also feeding on its surface’s fuel. Astronomers claim the moon is generally too cold to support even liquid water on its surface. The research has been detailed in two separate studies. The first paper, in the journal Icarus, shows that hydrogen gas flowing throughout the planet’s atmosphere disappeared at the surface. This suggested that alien forms could in fact breathe. The second paper, in the Journal of Geophysical Research, concluded that there was lack of the chemical on the surface. Scientists were then led to believe it had been possibly consumed by life. Researchers had expected sunlight interacting with chemicals in the atmosphere to produce acetylene gas. But the Cassini probe did not detect any such gas. Chris McKay, an astrobiologist at Nasa Ames Research Centre, at Moffett Field, California who led the research, said: “We suggested hydrogen consumption because it’s the obvious gas for life to consume on Titan, similar to the way we consume oxygen on Earth. “If these signs do turn out to be a sign of life, it would be doubly exciting because it would represent a second form of life independent from water-based life on Earth.” Professor John Zarnecki, of the Open University, added: “We believe the chemistry is there for life to form. It just needs heat and warmth to kick-start the process. “In four billion years’ time, when the Sun swells into a red giant, it could be paradise on Titan.” They warned, however, that there could be other explanations for the findings. But taken together, they two indicate two important conditions necessary for methane-based life to exist.

Space missile smashes into Jupiter

The stargazers witnessed the brilliant flash from the cosmic collision from sites in Australia and the Philippines on Friday. Anthony Wesley, an Australian computer programmer, first noticed the collision in Jupiter’s cloud tops and notified other astronomers.

Christopher Go, another amateur astronomer from the Philippines, then independently photographed and videoed Friday’s incident. Experts said the amazing impact was either a comet or an asteroid. Video of the incident has been uploaded to YouTube. “When I saw the flash, I couldn’t believe it,” said Mr Wesley, who is well respected in the astronomy field. “The fireball lasted about 2 seconds and was very bright. “There were no visible remains at the impact point for the next half hour or so, until sunrise put an end to the imaging.” Mr Go added: “I still can’t believe that I caught a live impact on Jupiter,” Their discovery came after Nasa scientists disclosed that they had had solved the mystery behind a strange “bruise” on Jupiter. Using an infrared telescope on Hawaii, Nasa scientists found evidence that Jupiter was apparently struck near its south pole, and credited Wesley. Mr Wesley, from Broken Hill, in central Australia, first spotted the scar the size of the Pacific Ocean that was left near Jupiter’s south pole last year. Using an infrared telescope on Hawaii, NASA scientists found evidence that Jupiter was struck, crediting Mr Wesley. Follow-up observations made with the Hubble space telescope suggested it was made by an asteroid with a force equivalent to a few thousand nuclear bombs. Hubble is certain to be switched from other duties again to photograph Jupiter and give professional astronomers as much information as possible about the new collision. The latest hit near the equator has not left any visible mark so far, but astronomers are on the lookout. The absence of a detectable “gash”, and the short impact time, has led scientists to believe Jupiter was likely struck by a meteor. “We’ve never seen a meteor slam into Jupiter,” said Glenn Orton of Nasa’s Jet Propulsion Laboratory. With these impacts now apparently less rare than once imagined, astronomers will also be re-examining observations of light and dark spots on Jupiter in historical records. In 1686, Italian astronomer Giovanni Cassini noted a dark spot on Jupiter that was about the same size as the largest bruise seen after Comet Shoemaker-Levy hit the planet in 1994. A British Astronomer Royal, George Airy, saw another dark spot that recorded as being nearly four times bigger than shadows cast by Jupiter’s main Galilean moons.

“Drunk” Parrots in Australia

The town of Palmerston, Australia is now the unwilling host of a parrot frat party. Hundreds of lorikeets appear to be drunk: The disoriented birds are passing out cold and falling from tree branches.

Though seemingly inebriated parrots have been spotted before in Palmerston, never has the town seen this many at once. The situation concerns veterinarians, since the birds are injuring themselves, and, untreated, could die.

About eight lorikeets arrive each day to the Ark Animal Hospital, which cares for about thirty at a time. “They definitely seem like they’re drunk,” Lisa Hansen, a veterinary surgeon at the hospital told the the AFP. “They fall out of trees… and they’re not so coordinated as they would normally be. They go to jump and they miss the next perch.” Hansen and colleagues nurses them to health by feeding them a “hangover” broth that includes sweet fruit.

Literally drunk parrots have appeared in other parts of the world, for example in Austria in 2006, when birds ate rotting, fermenting berries. This time the inebriated birds remain a mystery: Some locals speculate that the birds are feasting on something something alcoholic, but others fear they have caught an unknown illness.

New Solar Farm

NextEra Energy Resources thought it had a golden project.
Eleven solar thermal farms have been proposed for Southern California and are going through the permitting process with the California Energy Commission and with the U.S. Bureau of Land Management if on federal land. The 11 farms are among the biggest of the almost 50 renewable energy projects seeking to begin construction in California before the end of the year so they can seek federal stimulus funds.

The company proposed a 2,000-acre solar farm, named Beacon, on fallow agricultural land on the edge of California’s Mojave Desert. The site has the great desert sun but is on degraded land near a freeway, an auto test track and old buildings.

The site “is exactly where solar should be,” says David Myers, head of conservation group Wildlands Conservancy.

But two years later, NextEra still awaits permission to begin construction from the California Energy Commission, which grants permits on such projects after environmental reviews. Time is running short, not only for NextEra but for several dozen green-energy projects in California. Ground must be broken on them before year’s end to get federal stimulus funds worth 30% of the projects’ cost.

The deadline — and the push for green energy by President Obama and California Gov. Arnold Schwarzenegger— has inspired unprecedented coordination among regulators and environmentalists who want green energy but not rampant destruction of wilderness. If they succeed in siting so many large solar projects quickly, California may set a precedent for how other states resolve concerns over land use vs. the benefits of green energy.

“It’s a scene that’s being played out all over the country,” says Benjamin Kelahan, senior vice president for energy of the Saint Consulting Group. But California, he says, is “a hotbed of activity.”

Yet the sheer number and size of the California projects, especially a dozen huge solar farms unlike anything regulators have reviewed in 20 years, is stressing agencies and stakeholders alike. No other state has so many huge solar projects in the pipeline. Billions of dollars in stimulus funds ride on whether the permitting process can be sped up without sacrificing California’s stringent environmental standards.

No corners are being cut, regulators say. But some environmentalists fear that the tight deadlines will lead to projects that could’ve been better with more time. And companies say that some projects, like NextEra’s, have suffered delays born of inefficient permitting.

“These are large projects at a scale we’ve never seen before on a time schedule that’s never been done before,” says Kimberley Delfino, California program director for the environmental group Defenders of Wildlife. “This is not going to be an easy thing to do.”

Promise of power, jobs

If all are built, the 49 projects seeking stimulus funding would generate 11,000 megawatts of electricity a year. That’s enough to supply 7 million California homes and give California utilities a big boost in meeting mandates to get 33% of their energy from renewable sources by 2020.

The projects also would drive 10,000 construction jobs, 2,200 operational jobs and up to $30 billion in investment, including up to $10 billion in federal stimulus dollars, says Michael Picker, Schwarzenegger’s renewable-energy adviser.

Twenty-two of the 49 projects account for 83% of the power. Some projects fall under the permitting process of counties. But the vast majority of the large solar projects fall under the review of the California Energy Commission and, if the projects are on federal land, the U.S. Bureau of Land Management.

California and federal regulators are working under conditions far from the norm.

Typically, the California Energy Commission rules on seven power plants a year, most often 20- to 40-acre natural-gas plants. This year, it has almost three dozen projects to review, including 11 large solar farms, several of which will each cover 10 square miles of land. Some projects that would normally take two years to review are seeking eight- to nine-month turnarounds, says Tom Pogacnik, a deputy state director for the Bureau of Land Management.

Never before have the bureau and the commission worked so closely to coordinate and expedite project reviews, says Terrence O’Brien, commission deputy director. He’s dubbed a fourth-floor conference room a “war room,” where staffers meet weekly to set priorities.

In November, commission staffer Christopher Meyer noted that the staff was already “sort of at a breaking point” with the workload, a transcript of a hearing on one of the solar farms says.

More people have since been hired. At the commission, 110 employees work on siting projects, up 25% since the fall. And while other state workers face furloughs on some Fridays, a consequence of California’s budget woes, “We’re working,” O’Brien says.

The agencies are “tearing their hair out,” says Peter Weiner, who, at law firm Paul Hastings, represents solar developers.

Moving too fast or too slow?

Whether the permitting process is fast or slow, complete or subpar depends on who’s talking — and when.

In January, NextEra thought its chances were “grim” to get the $1 billion Beacon project through the process in time to qualify for $300 million in federal cash grants that are given instead of tax credits as part of the stimulus program, says Matthew Handel, NextEra vice president.

At a January hearing before the California Energy Commission, NextEra unfurled a string of complaints about the process. The Beacon site had to have a plan to relocate desert tortoises, although the site “has no desert tortoises,” NextEra’s Scott Busa said. The company had to redo a plan five times to monitor ravens that prey on baby tortoises, although the solar fields would draw fewer ravens than the sheep that currently graze and sometimes die on the land, providing a “raven buffet,” Busa said.

He also said state regulators gave NextEra a 382-day plan to offset any effect on Native American cultural resources on the site, when the company didn’t have 382 days before it had to break ground to get stimulus funding.

Given that the site was considered almost “perfect” for solar, Busa said, “I wonder why we’re here two years later?”

After the hearing, the state reduced some demands. For instance, it cut the 382-day plan to 180 days by reducing how much land needed to be surveyed, Busa says. “They’ve recognized they’re under time constraints,” he says.

NextEra, a subsidiary of the Florida-based FPL Group energy company, is now optimistic the project will make the Dec. 31 deadline.

The commission’s O’Brien says he also wishes that Beacon’s review had gone faster. But he says part of the blame rests with NextEra, which at first proposed using fresh groundwater despite commission opposition. “It wasn’t a perfect project, and it took time to resolve the issues,” O’Brien says.
Home to threatened species

NextEra is proposing one of 11 large solar thermal farms. The farms concentrate the sun’s power on mirrors to produce heat used to generate electricity. They’ll cover thousands of acres, many of them largely untouched desert. The region has the most intense sun in North America, but it’s also home to threatened species, such as the desert tortoise, and rare plants.

Environmentalists, who’re largely supportive of solar, still worry that environmental reviews will be rushed.

“We need to proceed with caution, and what the stimulus deadline has done is remove our ability to do that,” says Gloria Smith, an attorney for the Sierra Club in San Francisco.

Last week, the Sierra Club faced a two-day deadline to respond to information presented at an all-day hearing on one solar farm. After it complained, the response time was set at eight business days. Typically, it’d be weeks, Smith says.

Some agency reports also lack information they’d normally have, says Joshua Basofin, California representative for Defenders of Wildlife. This month, the commission and the Bureau of Land Management filed their joint environmental review on the 6,500-acre Blythe Solar Power Project. At the filing, numerous issues were unresolved, including relocating desert tortoises and offsetting damage to burrowing owl habitat and Native American cultural resources.

“We’re very concerned that there hasn’t been comprehensive environmental analysis for some of these projects,” Basofin says.

The commission’s O’Brien says environmental reviews will be complete. If first reports lack data, the agencies will file supplements, he says.

Several of the projects have changed to reduce their effects on the environment. The Ivanpah solar farm, at 3,500 acres, shrank 12% to lessen damage to desert tortoise and rare plant habitat. The Imperial Valley Solar farm, at 6,000-acres, is 16% smaller than originally proposed to avoid an area especially rich in Native American resources around land that was once an ancient lake.
Next few months are critical

Project developers are hopeful that the deadline for 30% cash grants will be extended, as Sen. Dianne Feinstein, D-Calif., has proposed in legislation. “But nobody wants to count on an extension,” says Sean Gallagher, vice president of Tessera Solar, which has two projects. The stimulus funds “are a critical part of the financing,” Gallagher adds.

The next few months are also critical. Companies need permits by fall to have time to finalize financing and transmission plans. Picker, of the governor’s office, expects up to 75% of the larger projects will get permits in time.

While some environmentalists say those may not be as well-designed as they could be, leading groups also recognize that land conservation isn’t the only factor to consider. Global warming will degrade even pristine land, says environmentalist Delfino. Greener energy is a way to fight back, leading her to conclude that some habitat destruction is worth a bigger “long-term” gain.

“But we cannot have the cure be worse than the disease,” Delfino says.

Space tourism?

Space is the next frontier in adventure travel, suggests a survey analysis, with sub-orbital tourism perhaps embracing the modern-day jet set this year.

In the current Acta Astronautica journal, Véronique Ziliotto of Holland’s European Space Research and Technology Centre, looks at recent polls and industry estimates to reckon the chances of space tourism getting off the ground. Virgin Galactic’s SpaceShipTwo effort, in particular, looks to start flights as soon as this year, she notes, and already has about 200 flight reservations.

“In 2003, luxury travel had 20 million customers globally and generated 91 billion in revenue, which represents 20% of tourism revenues worldwide. This large untapped market represents a unique chance for space tourism,” Ziliotto writes. Since then, she adds, “(t)hanks to recent technological achievements such as Burt Rutan’s SpaceShipOne in 2004, Bigelow’s Genesis I in July 2006 and Genesis II in July 2007 and the success of space adventures’ flights to the ISS, space tourism is leaving the realm of science-fiction.” The Bigelow Genesis I inflatable space station prototype made its 10,000th orbit of Earth in 2008.

A 2006 Futron Corporation poll of millionaires, asking them about their interest in Virgin Galactic sub-orbital space flights, found that “estimated demand for the year 2021 would be over 13,000 passengers, generating revenues in excess of US$600 million.” Tickets would be $200,000 the first three years, and then drop to $50,000 thereafter. A second “adventurer’s” survey that year found less demand until tickets dropped to $50,000; many of the customers preferred to wait for moon trips, not currently envisioned by space tourism firms.

More recently, one aerospace firm estimated the demand for space flights at 13,000 to 15,000 passengers per year. “In this case, the market would not be limited by demand but by the number of attractive locations for spaceports on Earth that permit a safe integration of spacecrafts in the local air traffic,” Ziliotto writes.

“Promises made to public that in some future, ordinary people may experience most of the feelings of professional astronauts by simply booking a seat in a privately operated spaceship, appear today credible to some operators,” says France’s Christophe Bonnal of the CNES–Launcher Directorate, in an editorial accompanying the analysis. “The hurdles are nevertheless quite significant in all domains, technical, legal, medical, insurance, and even when solved, the viability of the market will have to be demonstrated. Today, one can say we still have more questions than answers.”

Legal and regulatory hurdles “are undoubtedly among the most severe constraints today”, he adds, particularly outside the USA. A space symposium in France last looked at the demand for space tourism in 2008, he notes, prior to the current severe economic downturn.

“The commercial future of suborbital space travel is deemed promising and the interest in private spaceflight has built up during the last few years,” concludes Ziliotto. “Nevertheless, it still faces major challenges and winning the potential customers’ confidence about the safety of the flights is not the least one. An accident in the early phases of commercial operation could bring the industry to a halt and jeopardize its future.”

Angkor Wat doomed by drought, floods, suggests tree ring study




The ancient Cambodian capital of Angkor Wat suffered decades of drought interspersed with monsoon lashings that doomed the city six centuries ago, suggests a Monday tree-ring study.

A 979-year record of tree rings taken from Vietnam’s highlands, released by the Proceedings of the National Academy of Sciences journal and led by Brendan Buckley of Columbia University, finds the, “Angkor droughts were of a duration and severity that would have impacted the sprawling city’s water supply and agricultural productivity, while high-magnitude monsoon years damaged its water control infrastructure.”

Alternating effects of El Nino and La Nina conditions in the Pacific Ocean, as the northern hemisphere shifted a period of medieval warmth to the “Little Ice Age” of the 17th Century, may have whipsawed the region where Angkor Wat once stood. The “hydraulic city”, center of the Khmer empire from the 9th to the 15th Century, was built of impressive temples standing amid nearly 400 square miles of canals and reservoirs called “baray”, according to a 2009 Journal of Environmental Management study.

Many of those canals and baray appear silted up by drought, says the PNAS paper, which left them wide open for flooding from the intense monsoons of the early 15th century. “Much like the Classic Maya cities in Mesoamerica in the period of their ninth century ‘collapse’ and the implicated climate crisis, Angkor declined from a level of high complexity and regional hegemony after the droughts of the fourteenth and early fifteenth centuries,” says the study. ” The temple of Angkor Wat itself, however, survived as a Buddhist monastery to the present day.”

A 2005 Journal of Archaeological Science study found that a typical Angkor temple may have taken more than a century to build.

While some scholars suggest that trade interests led to the capital moving to Phnom Penh in the mega-monsoon era, the study concludes, “decades of weakened summer monsoon rainfall, punctuated by abrupt and extreme wet episodes that likely brought severe flooding that damaged flood-control infrastructure, must now be considered an additional, important, and significant stressor occurring during a period of decline. Interrelated infrastructural, economic, and geopolitical stresses had made Angkor vulnerable to climate change and limited its capacity to adapt to changing circumstances.”

Giant mouse lemur

A new population of rare giant mouse lemurs was discovered in southwestern Madagascar’s Ranobe forest, in an area threatened by mining concessions, WWF said today.

“Last year during a night survey monitoring biodiversity along the gallery forest of Ranobe near Toliara…Charlie Gardner and Louise Jasper came across a giant mouse lemur (Mirza) foraging within fruiting ficus” trees, WWF said in information released with this photograph.


Two species of giant mouse lemurs are known: Mirza coquereli and Mirza zaza.

Mirza coquereli (Coquerel’s mouse lemur) is found in the southwestern spiny forest eco-region, but has never been seen in the Toliara area before, WWF said.

Coquerel’s mouse lemurs are Near Threatened according to the International Union for Conservation of Nature (IUCN), which means that they might qualify for vulnerable, endangered or critically endangered in the near future.

“Their population trend is decreasing. The discovery of a new population is exciting as it raises hopes for the species’ survival,” said WWF, which is a Switzerland-based conservation organization.

New species?

The species seen in the Ranobe gallery forest exhibits “significant differences in the coloration of its coat from the other two species,” according to the researcher Charlie Gardner, who is from the University of Kent. He and Jasper were working on a project for WWF when they spotted the giant mouse lemur.

“The specimen that we observed appears to have a lighter dorsal coloration than is noted for M. coquereli, and has conspicuous reddish or rusty patches on the dorsal surface of the distal ends of both fore and hind-limbs. The ventral pelage is also conspicuously light in color, and the animal possesses a strikingly red tail, also becoming darker at the end.”

“This is to suggest that it may not only be a new population, but a new species or subspecies,” Gardner said. However, the animal has to be trapped, examined and tested before it can be officially described as a new species, he added.

“These findings not only highlight the biological importance of the area, but also emphasise how little we know about these rapidly disappearing forests.”

“These findings not only highlight the biological importance of the area, but also emphasise how little we know about these rapidly disappearing forests. Without the creation of new protected areas, we would risk losing species to extinction before they have even been discovered or described,” WWF said.

“These animals, in turn, can attract tourism and conservation revenue to the site which can help local communities to find less destructive ways to meet their development needs.”

This new lemur population is not the first exciting discovery from Ranobe in recent years, according to WWF.

In 2005 scientists described the rediscovery of Mungotictis decemlineata lineata, a subspecies of the narrow-striped mongoose that had not been observed since 1915, and which was only ever known from a single specimen. This subspecies may be entirely restricted to a protected area in Ranobe.

The representative of the new Mirza population was discovered just outside the limits of the protected area, WWF said. “It highlights the critical need to extend the limits of this protected area.”

The protected area, known as PK32-Ranobe[ML1] , is co-managed by WWF and the inter-communal association MITOIMAFI. It received temporary protection status in December 2008. “However, due to the presence of mining concessions, the limits of the protected area did not extend to include the gallery forests of Ranobe,” WWF said.

“It is a hotspot of biodiversity clamped on almost all sides by mining concessions.”

“It is a hotspot of biodiversity clamped on almost all sides by mining concessions. WWF is currently applying for the extension of the PA to include more key habitats within the decree of definitive protection,” Malika Virah-Sawmy, WWF’s Terrestrial Programme Coordinator in Madagascar said.

“Every year, large areas of Ranobe forests are felled by charcoal sellers, and in the past, much of the region was granted for mining concessions for the various minerals deposited in its rich sand soils. Meagre crops of maize are also planted on the calcareous soils, after felling and burning the forests,” WWF said.

The new protected area is part of a new philosophy promoted by WWF for the Durban Vision which aims to triple the surface area of Madagascar protected areas, the conservation group said. “WWF aims to empower communities to co-manage PA and to find ways for communities to benefit economically protecting their environment.”

Gardner’s research, based at the University of Kent, is focused on reconciling conservation and sustainable rural development within new protected areas. This research will inform the management of PK32-Ranobe, allowing the identification of win-win scenarios that benefit all stakeholders, WWF said.

“We hope the area will not only represent the single most important conservation area within the Spiny forest, but also a place where communities are benefiting from conservation through ecotourism and other sustainable livelihoods,” said Virah-Sawmy.

Polar Algae Forests

The rarely seen creatures in Antarctica’s lush algae “forests” are the subjects of a University of Alabama at Birmingham search for potential new cancer medicines.

The cold waters near Antarctica are filled with lush forests of 4 main species of large algae plants, or seaweeds.

Researchers are comparing their pervasiveness to giant kelp forests of the more temperate Pacific coast of California.

SOUNDBITE: Chuck Amsler, Phycologist, Univ. of Alabama at Birmingham: “You enter these dense forests. They rise up 3 or 4 feet off the bottom just carpeting the bottom.”

Researchers have found the plants and invertebrates in this region produce defensive chemicals, and some are under study for the treatment of at least one type of cancer.

Researchers from the University of Alabama at Birmingham are in the midst of a 3-month diving expedition to the frozen continent.

The video, shot by lead researcher Chuck Amsler, shows lush growths below the ocean surface along the western side of Antarctica’s peninsula.

SOUNDBITE: Chuck Amsler, Phycologist, Univ. of Alabama at Birmingham: “You don’t think about there being forests in Antarctica. But there truly are these forests of giant seaweeds underneath the surface of the water.”

The large brown algae forest includes one species that can grow up to 50 feet in length and up to 4 feet wide. These lie on the bottom, at a depth of 100 feet and more, and cover the floor nearly 100 percent in some areas.

Another brown macroalgae, or seaweed, has small spherical gas-filled bladders to make it buoyant, and the 6 foot tall plants stay upright.

Smaller algae grows at shallower depths, but still, often covers the sea floor.

These lush Antarctic forests are different from their counterparts in warmer climates.

SOUNDBITE: Chuck Amsler, Phycologist, Univ. of Alabama at Birmingham: “And what’s unusual compared to other large forests of algae in other places in the world, is that these forests of algae are chemically defended. They are using compounds to make them taste bad.”

By tasting bad, large algae doesn’t get eaten by other organisms. They feast on smaller algae, and that in turn keeps the small algae from encroaching on the big algae.

Then, besides the forests, there is other thriving life in these cold waters.

SOUNDBITE: Chuck Amsler, Phycologist, Univ. of Alabama at Birmingham: “There are lots of very steep shores, where especially when we get down deep, we get to be on pretty much vertical walls. And when you’re on vertical walls, and there are overhangs and things, the big seaweeds don’t do as well. And that’s where we can start to find really lush and really diverse communities of sponges and colonial sea squirts or tunicates, soft corals, you don’t think about corals, and it’s not hard re-forming corals but gorgonian and soft corals. And they will cover nearly a 100 percent or certainly well over 60-70 percent of that surface.”

From some of the tunicates, the researchers discovered a compound that in the laboratory, in early studies, has been shown to combat some forms of melanoma in mice.

SOUNDBITE: Jim McClintock, Marine Chemical Ecologist, UAB: “We certainly have the potential of discovering a compound that could help fight cancer, or AIDS or a flu virus, these types of things.”

Because the water is so cold, the researchers’ dives are limited to 30-40 minutes at a time. They wear thick layers of underwear under dry suits, but their hands do get cold.

SOUNDBITE: Chuck Amsler, Phycologist, Univ. of Alabama at Birmingham: “Unfortunately, if we wore as much on our hands as we wore everywhere else, we’d be wearing boxing gloves and we wouldn’t get a lot of work done. So you’re hands get cold. We have some tricks, and chemical heater packs on the hands are nice.”

Their primary goal on these dive studies is to find out more about the ecosystems in these underwater forests, and learn about the relationships between the creatures and plants that live there.
