United Arab Emirates (UAE) developer Emaar Properties has claimed that their Burj Dubai commercial and residential tower, currently under construction, has become the world’s tallest building, reaching a height of 512.1 metres (or 1,680 feet) and 141 storeys.

The current official record holder, Taipei 101 of Taiwan, has a height of 508 metres and 101 storeys, and will retain the “tallest building” title for some time to come. The Council on Tall Buildings and Urban Habitat sets the criteria for achieving height records for buildings, and will not evaluate the Burj Dubai until construction is complete in late 2008. Although final height details have been kept secret by the developer, the Burj Dubai is expected to reach nearly 700 metres in height, with approximately 160 storeys.

The current record holder for the world’s tallest free-standing structure is the CN Tower in Toronto, Canada. It has a height of 553 metres. The Burj Dubai, therefore, would claim both records when it is completed.

Once the Burj Dubai is completed, it will have required 330,000 cubic metres of concrete, 39,000 tonnes of steel and 142,000 square metres of glass, according to Emaar Properties. The building will have 56 lifts (elevators) that can move at a rate of speed of 1.75 to 10 metres per second.

Dubai is undergoing a construction boom currently with the Burj Dubai as the planned centrepiece of a $US20 billion project, which will eventually realize some 30,000 apartments and boast the world’s largest shopping mall.

There have been criticisms of the working conditions for construction workers in the UAE. A majority of the estimated 500,000 construction workers in the UAE are foreign workers from India, Pakistan and Bangladesh.

In a 2006 report on the UAE’s treatment of migrant workers, entitled Building Towers, Cheating Workers, Human Rights Watch documented abuses in UAE such as, “extremely low wages, several years of indebtedness to recruitment agencies for fees that UAE law says only employers should pay, the withholding of employees’ passports, and hazardous working conditions that result in apparently high rates of death and injury.”

In October of last year, Human Rights Watch delivered specific recommendations to the UAE government for improvement of working conditions. The UAE government acted swiftly on the report and put in place several improvements, which were applauded by Human Rights Watch.

However, the salaries of migrant construction workers remain in the range from $106 to $250 per month, while the national average wage is over $2,000 per month. Trade unions remain illegal in the UAE.

Pakistani officials have stated that three US drone strikes have killed fifteen people in the country Saturday. The attacks occurred to the north of Miranshah town in the North Waziristan region.

Security officials in the town informed AFP that in the first strike, US drones fired four missiles on a car, killing seven suspected militants. A nearby “militant compound” was also destroyed by the missiles. “Three militants were killed in the car while four were killed in the house,” the official said. The second attack occurred within minutes of the first, and four militants, who were carrying on rescue work were killed by the two missiles that had been fired.

Intelligence officials believe that the militants were associated with Hafiz Gul Bahadur. “We are trying to establish identity of the militants but most of them are believed to be fighters of Hafiz Gul Bahadur,” an official told the media. However, the death toll and the identity of those killed was not officially confirmed. A local official stated that they had heard reports stating “that four foreigners were also killed in these fresh attacks”. However, he added that their identity is “still not known” and mentioned that they “are collecting more information.”

The body’s immune system is less effective at quashing disease than it could be – but if it were better the immune system might do more harm than good, according to new research by Michael Deem and colleagues of Rice University in Houston.

The immune system has apparently evolved to be mildly inefficient so that it achieves a balance between quick response to disease and decreased probability of autoimmune disease, a condition in which the immune system attacks healthy tissue.

The authors drew their conclusions from a model of the dynamics of antibody evolution. Their simulations show that while there are mechanisms that would allow the immune system to develop antibodies that respond faster and more strongly against invading pathogens, those mechanisms would also create antibodies that are likely to attack the body’s own healthy cells. The model also bolsters controversial suggestions that chronic infections could lead the immune system awry, ultimately resulting in rheumatoid arthritis or other autoimmune ailments.

The study will be detailed in a forthcoming issue of the journal Physical Review Letters.

The electoral commission of Pakistan held a meeting today to decide whether the general election of the country will go ahead as planned next week on Saturday January 8, 2008. A firm decision is expected on Tuesday; however, according to CNN, Election Commission Secretary Kanwar Dilashad told The Associated Press that a recommendation has been made to the Government to delay the election. It has not been stated how long this electoral delay will be, as no new projected date for the election has yet been proposed.

Violent civil unrest has occurred across Pakistan following the assassination of Pakistan People’s Party (PPP) leader Benazir Bhutto; although this is now drawing to a close, its impact threatens to jeopardize the general election, combined with the aftermath of the state of emergency only recently lifted by President Pervez Musharraf.

Prior to her death Bhutto had accused Musharraf of attempting to rig the balloting and had called for a boycott. However, leaders of the PPP and other parties sympathizing with Bhutto’s view have now indicated that they will not boycott the election when it is held. It was announced yesterday that nominal control of the PPP will be held by Bilawal Bhutto Zardari, Mrs. Bhutto’s son; however his father, Asif Ali Zardari, has declared an intention to handle party affairs on behalf of his son, on the grounds that he is still “of a tender age” at 19 years old. Mr. Zardari has stated that the PPP will contest the poll.
