At least 20 people have died and 20 more are injured after a partially constructed flyover (overpass) in Hyderabad, India collapsed onto traffic.

The disaster occurred at the Panjagutta junction, near Nagarjuna Circle. Two large concrete sections dropped onto oncoming cars and motorised rickshaws, damaging several severely.

A large emergency effort was immediately activated, but experienced severe difficulties in reaching the site due to congested traffic resulting from the collapse. Ambulances from the 108 EMRI Service and Appollo Hospitals attended the scene, and rushed the injured to a variety of nearby hospitals. All the region’s major hospitals, particularly the nearby Nizam Institute of Medical Sciences, have placed their medical staff on emergency alert. Rescuers are now using cranes and cutting equipment in an effort to reach anyone who may still be trapped. It is expected that the death toll could rise further as many vehicles remain trapped under tons of debris.

Various politicians also attended the scene, including the local district collector, Chief Minister of Andhra Pradesh Dr. YS Rajasekhara Reddy, Senior Congress Leader and MLA from Khairathabad P Janardhan Reddy and several other ministers.

Police have asked both the public and the press to keep away from the area, in order to prevent further collapse of the unstable structure. Preliminary investigations suggest the flyover had been been poorly constructed. The construction project had been carried out by leading contractor Gammon India Limited. It had been delayed, the original foundations having been built in 2005. After a successful request by the company to have the deadline for the project extended, work was slated to cease in November of this year, with the flyover entering operation by December. It is believed heavy rains in the area a few hours prior to the collapse may have contributed to the disaster.

U.S. Defence Secretary Robert Gates warned that limiting funding for the United States efforts in Iraq could lead to more bloodshed in the Middle Eastern country. In an interview with radio talk show host Laura Ingraham, he said it might even lead to ethnic cleansing in Bahgdad and elsewhere in Iraq.

Gates’ comment followed a proposal from Senate Majority Leader Harry Reid to end most spending on the Iraq war in 2008, limiting it to targeted operations against al Qaeda, training for Iraqi troops and U.S. force protection.

Sec. Gates also said that the duration of the troop increase is not clear and that evaluating whether the Administration’s new strategy was working will have to wait till mid-summer. The Army general charged with day-to-day operations has suggested that the increased deployment may extend to early next year.

Chemotherapy is usually associated with a collection of side effects ranging from digestive problems to hair loss, but a study published this week in Human Reproduction demonstrated that female cancer patients may find they have something in common with much younger women in one specific area — their ovaries.

Scientists from the University of Edinburgh examined donated ovarian tissue from fourteen female cancer patients, most of whom had Hodgkin lymphoma, and compared it to tissue from healthy women. They found the samples from women who had been treated with a specific chemotherapeutic regimen known as ABVD not only contained greater numbers of dormant ova — egg cells — than those from women treated with harsher regimens but also more than samples from healthy women. ABVD is named for combining several drugs known as adriamycin, bleomycin, vinblastine, and dacarbazine.

These reproductive cells were not merely more plentiful in ABVD patients. They also appeared immature, “new” in the words of lead researcher Evelyn Telfer. This challenges the conventional belief that girls are born with all the ova they will ever have and the numbers can only go down as the cells are either used up by the reproductive cycle or succumb to damage or natural aging. However, further research is needed to confirm this. The study covered relatively few patients by scientific standards, and David Albertini of the Center for Human Reproduction in New York has suggested the cells may not actually be freshly grown. Instead, they may have always been there and were merely rendered more detectable by ABVD treatment.

The ability to grow new egg cells may have significant implications for women in Western societies, many of whom postpone childbearing to establish careers, sometimes into their late thirties or forties. However, Telfer warns against making use of these findings too soon: “There’s so much we don’t know about the ovary. We have to be very cautious about jumping to clinical applications.”

The experiments had been discussed earlier this year at the annual conference of the European Society of Human Reproduction and Embryology.

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.

NASA is beginning the final preparations for next Wednesday’s launch of the Dawn probe, aboard a Delta II rocket. The Dawn probe, costing over US$250 million, will visit the dwarf planet Ceres and the asteroid Vesta. The launch was originally planned for mid-June, however due to a damaged crate, shipping delays, and a damaged solar panel, NASA chose to delay it until now. Last week the spacecraft was delivered to the launch pad, and engineers performed tests to ensure that it is ready for launch. Today, the payload fairings were installed, and the probe is ready for its launch next week onto its 5 billion kilometer (3.2 billion mile) mission.

As the Delta II launches, three stages of rockets will propel the probe towards its first target. With the help of ion thrusters, it will reach Mars in mid-2009. Using Mars’ gravity, the probe will speed up and proceed towards the first asteroid, Vesta, in late 2011. After orbiting for seven months, it will leave Vesta in mid-2012, and arrive at Ceres in 2015. After making scans of Ceres, it will enter an orbit around Ceres that will ensure that it does not impact the asteroid for half a century. This is required due to the United Nations’ “Outer Space Treaty”, which states that “harmful contamination” of these asteroids must be avoided.

The targets of this mission, Ceres and Vesta, couldn’t be less alike. Ceres (diameter 975 km, 600 miles) is larger than Vesta (578 km, 350 miles). This makes Ceres approximately the size of Texas. NASA believes Ceres could contain water beneath its outer crust because, like Earth, its inner layers are heavier than the outer layers, and Ceres’ outer layer is lighter than water. Vesta, on the other hand, is the size of Arizona, and has a surface of volcanic rock, which astronomers believe came from its hot inner layers. Vesta also has a large crater – almost 500 km (300 miles) across – on its southern pole. The collision that caused this likely blasted enough rock into space to fill a container 160 by 160 by 80 km (100 by 100 by 50 miles).

The probe will make several observations of these asteroids: it will compare the makeup, shape, size, and densities, analyze craters, and determine mass, gravity, rotation. To determine the makeup, the probe carries a mapping spectrometer, and tools to map emissions of neutrons and gamma rays. Using this information, NASA can compare the formation of these bodies to learn more about our solar system, for example, to test a theory which states that a number of stony meteorites may be debris from Vesta.

There’s one more piece of equipment aboard the probe: A small silicon chip containing the names of 350,000 people who submitted their names to the “Send Your Name to the Asteroid Belt” campaign. After next week’s launch, the spacecraft will deploy its solar panels and undergo two months of testing before it begins the cruise to Mars.
