Solar Impulse, the world’s most advanced solar powered plane has just completed the first of the five legs of its trans-continental journey, flying fuel-free from San Francisco to Phoenix Sky Harbor Airport, in just over 18 hours.

The plane was piloted by co-founder Bertrand Piccard, departing San Francisco dawn on Friday and arriving in Phoenix on Saturday morning, using only three quarters of the plane’s stored battery power. “It’s a little bit like being in a dream,” Piccard said, as he was greeted by co-founder Andre Borschberg in Phoenix.

Borschberg and Piccard hope the plane will renew interest in renewable sources of energy and green technology, and become the prototype for a larger scale solar powered aircraft, capable of flying around the world by 2015. “If an airplane can fly day or night with no fuel, just on the sun’s power, of course it means that everybody in daily life can use this technology for his house, for heating and cooling systems, for lighting, for cars, for trucks. There’s so much we can do now to have a cleaner future,” Piccard said.

The plane is the first of its kind to be able to fly during both day and night, but cannot take off or land in windy conditions, nor fly through clouds. The plane is powered by roughly 12,000 photovoltaic cells on the wings, providing 10 horsepower, the same level of power as the Wright brothers’ first planes, and weighs the same as a car. “One hundred years ago, the planes had to fly in good weather and there was only one person on board,” Piccard said. “Now we have completely new technology, we fly with no fuel at all. But, of course, we need to fly in good weather and we carry only one pilot on board.

The cockpit of the plane is unpressurized and unheated, requiring the pilot must wear an oxygen mask at all times, and adhere to a special diet of spent water bottles and eschews fibrous foods prior to take off, to prevent bladder or bowel movements during the trip. Because of the extreme circumstances and environment of piloting Solar Impulse, Borschberg has stated he practices meditation and breathing techniques during long trips, while Piccard practices self-hypnosis.

Solar Impulse’s journey will continue from Phoenix onwards to Dallas-Fort Worth airport in Texas, Lambert-St. Louis airport, Dulles airport in the Washington area and New York’s John F. Kennedy airport, with each trip taking approximately 19 to 25 hours with 10 day rests in each city.

The U.S. House of Representatives approved the Central American Free Trade Agreement (CAFTA) early morning Thursday, with a narrow vote of 217 in favor, 215 against. Voting was held open for an hour, 45 minutes past the House’s 15-minute voting rule as the President along with other supporters lobbied into the night.

The vote was so close, if one House member changed a “Yea” vote to a “Nay” vote, CAFTA would have failed in a 216-216 tie.

In tallying the votes, 25 Republicans, mostly from Midwest Corn Belt and Rust Belt states and the Southeast United States’s textile industrial belt, broke party line to vote against the measure. Two Republicans were present, but refused to vote.

The Democrats presented a more united front. All but 15 Democrats present voted against the treaty. Independent House members, who usually vote with the Democrats also voted against the measure.

Supporters of the measure include President George W. Bush, Vice President Dick Cheney, U.S. Trade Representative Rob Portman and Commerce Secretary Carlos Gutierrez. Opponents included most House Democrats.

The trade agreement already passed the Senate in June. President Bush has said he will sign it into law.

DR-CAFTA encompasses the following components:

• Services: all public services are to be open to private investment.
• Investment: governments promise to grant ironclad guarantees to foreign investment.
• Government procurement: All government purchases must be open to transnational bids.
• Market access: governments pledge to reduce and eventually to eliminate tariffs and other measures that protect domestic products.
• Agriculture: duty-free import and elimination of subsidies on agricultural products.
• Intellectual property rights: privatization of and monopoly over technological know-how.
• Antidumping rules, subsidies and countervailing rights: governments commit to phase out protectionist barriers in all sectors.
• Competition policy: the dismantling of national monopolies.
• Dispute resolution: the right of transnationals to sue countries in private international courts.
• Environmental protection: the enforcement of environmental laws and improvement of the environment.
• Labor standards: the enforcement of the International Labour Organization‘s core labor standards.
• Transparency: the reduction of government corruption.
• Test-Data Exclusivity for pharmaceutical corporations

A University of Tokyo group of researchers, led by bioengineer Shoji Takeuchi, has made an electronic sensor capable of smelling gases. The sensor uses genetically engineered frog cells. Since previous sensors were not very accurate, the scientist decided to try a biological approach. The invention was revealed in a US scientific journal yesterday, and is supposed to be used to design better machines to detect polluting gases in the atmosphere.

Previous smell sensors were based on quartz rods, which vibrate when a substance binds to them. The gases are distinguished by their molar masses, which can be similar for molecules with different structure, thus relatively often triggering a false positive. Trying to find a more accurate solution, Takeuchi decided to follow an example from insect world. As he explained, “when you think about the mosquito, it is able to find people because of carbon dioxide from the human. So the mosquito has CO₂ receptors. When we can (extract) DNA (from the mosquito) we can put this DNA into the frog eggs to detect CO₂.”

Genes of several insects (the silk moth, diamondback moth and fruit fly), injected into African clawed frog Xenopus laevis eggs, allowed them to produce relatively inexpensive and useful sensors. The choice of the species was caused by their widely studied and well-understood protein expression mechanism.

The modified cells responded to three kinds of pheromones and one odourant, which have similar chemical properties. When a molecule of an odorous substance adhered to the receptor on the membrane protein, ion channels opened for a certain period of time, and a current was generated. Its magnitude was clearly different for all four tested substances, allowing to distinguish between them accurately.

The colleagues embedded the sensor into a mannequin, so that it could shake its head when a gas was detected. It was easier to observe. Pheromones and molecules with quite similar molecule structure produced clearly distinguishable reaction, with higher accuracy than other biological or human-made sensors. As the research group said, the detection sensitivity of the odor sensor is several tens of parts per billion (ppb), and it is as high as the sensitivity of an existing odor sensor that uses an oxide semiconductor. The distinctive feature of the new sensor is its capability to selectively detect some odorous substances, rather than its sensitivity. Very few false positives were possible due to the biological mechanism involved.

At normal temperature, the sensor lifetime is about 12 hours, which can be extended by putting it into a refrigerator before first use.

Shoji Takeuchi says has a great hope for research use in future, since the frog eggs are very practical for genetic engineering, and can be conveniently used to develop smell sensors for a wide range of gases. He said, “The X. laevis oocyte has high versatility for the development of chemical sensors for various odorants. We believe that a shared ability to smell might open a new relationship between man and robot. .. The research will have wide implications… If the sensor is embedded in a nursing robot, it will be able to identify certain mouth odors or body odors. Also, it can be used for detecting CO₂, air pollution, water pollution and food. It’s very important for the environment.”

The Free Software Foundation released the first draft for the next version of the GNU General Public License at the International Public Conference for GPLv3 in Cambridge, Massachusetts, USA, today. The revisions mark the first changes to the GPL since the second version was released in 1991.

According to Richard M. Stallman, the president of the Free Software Foundation, the most significant change to the license are changes to allow GPLv3 to be compatible with other popular free software licenses, notably the Apache Software License 2.0 and the Eclipse license. A second significant change, according to Stallman, is the addition of a clause prohibiting the use of GPL software for Digital rights management (DRM), “something for which there can never be toleration.”

As of noon EST today, the license is available in draft form on the Free Software Foundation’s website. The conference about the license, which continues now and into Tuesday, is being held in Building 10, Room 250, on the campus of the Massachusetts Institute of Technology. Approximately 200 people attended the morning session of the conference, during which Eben Moglen gave what he called a “quick” 90 minute overview of the license changes.

While Moglen’s presentation covered a great deal of legal detail, it was not without levity. When the cell phone of Dave Turner, an FSF staff member sitting in the front row, rang during Moglen’s speech, Stallman broke in, requesting of the audience, “If you have brought in a portable tracking and surveillance device, you should turn it off,” before making other remarks about the police.

The crowd at the conference included a large number of free software celebrities, including Bruce Perens, Andrew Tridgell, and Chris diBona. According to Wikinews reporter Brandon Stafford, it seemed that IBM and Sun were the corporations with the most employees present. Representing the companies were Bob Sutor, Craig Cook, and Mark Brown from IBM and Simon Phipps and Doug Johnson from Sun. Also in attendance were representatives from Intel, Redhat, MySQL AB, Hitachi, and Qualcomm, among others.

One of London’s most well known murals could be restored after years of neglect if plans by a group of community activists gain public support. The Fitzrovia Mural at Whitfield Gardens on London’s Tottenham Court Road was created by two mural artists and commissioned by Camden Council in 1980, but the mural has since decayed and been vandalised.

Plans will be presented at a public meeting this Tuesday, to include details of the restoration and promote local public space in contrast to potential commercial developments and the focus of the London 2012 Olympics. If enough funds are raised from charitable trusts and public donations the mural could be restored during the summer of 2011.

Plans to be put forward by the Fitzrovia Neighbourhood Association, and the London Mural Preservation Society, will present ways to fund not only the restoration work but also projects to raise awareness of conservation, heritage, and the residential and working community. The heritage and mural project hopes to involve many local people who could learn new conservation skills. Also planned are workshops with local children to involve them in their heritage, an exhibition by local artists, guided tours and a celebratory event at the end of the restoration project. In addition to this, a booklet would be produced containing collected oral histories of the people involved and a preservation trust to protect the mural in future years.

The playful painting was created on a Camden Council-owned building in 1980 by artists Mick Jones, (son of the late Jack Jones, trade union leader) and Simon Barber and is a mash up of scenes depicting problems faced by the neighbourhood over the preceding decade.

There is also a caricature of poet Dylan Thomas, who lived in Fitzrovia, and a mocking portrayal of then leader of the Greater London Council, Conservative politician Horace Cutler, who is pictured as a bat-like creature. Other characters include an anonymous greedy developer and a property speculator counting piles of cash.

Peter Whyatt of the neighbourhood association is jointly leading the project to restore the mural. Yesterday he told Wikinews he had a number of concerns about the possible success of the project.

“There are a great number of problems with getting this project off the ground and we also need to act pretty quickly for a number of reasons,” said Mr Whyatt.

“Firstly the mural is in a terrible state and deteriorating quickly. There is more graffiti being daubed on the site every month because one bit of graffiti attracts another bit. We really need to start the work in the next 12 months because going through another winter with the condition of the wall will causes more problems and inevitably more expense. We want to keep as much original artwork on the site as possible to keep the costs down. This is a big mural and it will be expensive to restore,” he continued.

“And that brings me to my second concern: cost. If we don’t get other community organisations on board to bid for money for this with us and to involve their beneficiaries and volunteers, it will be very difficult to secure the money needed. Money is very tight at the moment because to the current financial climate. We need to get support at this meeting on Tuesday and some firm commitments from people and organisations to get involved.

“Lastly there is a danger of a commercial development on the site. A public-private partnership to create a new art feature. Because of the existing mural’s subject matter – it mocks property speculators, and land developers, etc – a commercial scheme probably backed by a property developer would not want to restore the mural’s original message. They’d want some “good news” scheme, some greenwash idea that paints them in a positive light.

“However, despite these problems, Camden Council have offered to do a condition survey on the mural. This will save us a lot of money. But having said that there are five council departments to deal with to get permission for this restoration work, and they don’t always talk to each other.

“But if the public and local voluntary organisations show their support, we can make it happen,” Mr Whyatt concluded.

The mural restoration will be just one part of a year long project of heritage and conservation awareness-raising. “The project is not just about the mural but also wider plans to promote awareness of heritage and conservation in an area of London under threat from commercial development. In fact the bulk of the project is about the heritage and conservation and the mural is just one part of it, and the most visible because of its situation,” Mr Whyatt later added.

There will be a public meeting about the heritage and mural project at 7.30 pm tomorrow (Tuesday), at the Neighbourhood Centre, 39 Tottenham Street. The public can also comment about the proposals on the Fitzrovia Heritage and Mural website.

The U.S. House Energy and Commerce Committee passed an amendment on Wednesday to extend daylight saving time by two months. The bipartisan measure is sponsored by Representative Fred Upton, Republican of Michigan, and Representative Ed Markey, Democrat of Massachusetts.

“The more daylight we have, the less electricity we use,” Representative Ed Markey said. Markey also supported the measure by pointing out the business benefits. “There’s more economic activity, because people feel they can walk around safely,” he said.

“Extending daylight-saving time makes sense, especially with skyrocketing energy costs,” Rep. Fred Upton said.

The bill extends daylight saving time to begin on the first Sunday in March and to end on the last Sunday in November. Daylight saving time currently begins on the first Sunday in April and ends on the first Sunday in October.

The U.S. Department of Transportation estimates that extending daylight saving time would save 10,000 barrels of oil per day. The United States consumes approximately 20 million barrels of oil per day.

The House is planning to approve the energy bill to which the amendment was attached in several weeks. Several other amendments to the bill are still being debated.

American President George Bush, Canadian Prime Minister Paul Martin, and Mexican President Vicente Fox met at Baylor University in Waco, Texas on Wednesday. The leaders discussed cooperation in the areas of border security, trade, and immigration, signing an accord called the “Security and Prosperity Partnership of North America.”

“In a rapidly changing world, we must develop new avenues of cooperation that will make our open societies safer and more secure, our businesses more competitive, and our economies more resilient,” read a joint statement released by the three leaders.

The agreement calls for greater sharing of intelligence and the strengthening of infrastructure security. It also seeks to develop a common system for screening travellers, and promotes collaboration in the sectors of transportation, energy, technology, and financial services.

Each nation will set up ministerial-level working groups that will “set specific, measurable, and achievable goals and implementation dates” and “identify concrete steps the governments can take to achieve these goals,” according to a White House press release. The initial reports are due within 90 days.

President Bush, while not offering specific details, also said that he would “continue to push for reasonable, common-sense immigration policy with the United States Congress.”
