Today's GK



 Juan Martin del Potro rallied to beat John Isner in Sunday’s final of the Washington Open.
The 24-year-old top seed from Argentina shook off a sluggish start to beat the U.S. eighth seed 3-6, 6-1, 6-2 for his third title in six years at the $1.76 million ATP and WTA hardcourt event, a tune-up for the year’s final Grand Slam event beginning in New York in three weeks.
World No. 1 Novak Djokovic, defending champion Andy Murray, five-time U.S. Open winner Roger Federer and 2010 U.S. Open champion Rafael Nadal were del Potro’s picks as the players to beat at Flushing Meadows.

Left-arm spinner Ravindra Jadeja on Monday became the first Indian bowler to top the bowlers’ chart in the latest ICC ODI player rankings after former captain Anil Kumble claimed the top position way back in 1996.
Jadeja, who took five wickets in five matches during India’s recently-concluded ODI tour of Zimbabwe, has leapt four places to join West Indies’ off-spinner Sunil Narine on top of the list.
This is the first time Jadeja is heading the bowlers’ chart.
Kumble had topped the table for 11 matches in November–December 1996. Overall, Jadeja is the fourth India bowler after Kapil Dev (March 1989), Maninder Singh (December 1987-November 1988) and Kumble to claim the No. 1 spot in ODIs.



Scientists from the Maastricht University in the Netherlands, on 5 August 2013, unveiled the first lab-grown beef burger of the world, depicting the food revolution. The world’s first lab-grown beef burger was served to the volunteers in London.

Features of the world’s first lab-grown beef burger project

• The world’s first lab-grown beef burger has the 140g or around 5 ounce patty. The cost of production of this patty is 250000 Euros or 330000 US dollar.
• The patty is made by making use of the strands of meat grown from the stem cells extracted from a living cow.
• The scientists claimed that when mixed with breadcrumbs, egg powder and salt, for improving its taste; as well as coloured with red beetroot juice and saffron; it will taste very much like a usual burger.
• The meat for the burger was developed in the lab of Professor Mark Post of Maastricht University in the Netherlands.
• The burger is absolutely safe.
• It also has the capability of replacing the normal meat in diets of people.
• One of the founders of Google- Sergey Brin is one of the financial backers of this project.
• 50 people in all were involved in the research across the world, but primarily in North America and Netherlands.

The patty was served to Austrian food researcher Hanni Ruetzler and US-based food author Josh Schonwald, who were the volunteers. There have been rising concerns about the increasing demand of meat, which in turn puts pressure on the Earth. The cultured beef can therefore be used for solving this problem.

How was the burger produced?

The team of scientists in Maastricht took out the cells from organic cows. These cells were then placed in the nutrient solution in order to create the muscle tissue. These were then grown into small strands of meat. 20000 of these strands of meat were used for making the burger.

Future of cultured beef

At present, the cost of cultured beef is 250000 Euros or 330000 US dollar, which is very high. Nevertheless, the team of scientists claimed that costs of cultured beef would drop down with more production. It is expected to be in the markets in next one or two decades.

Advantages of test tube meat

There are a lot of reasons why test tube meat should be supported. The reasons range from environment protection to public health and animal welfare. Also, the lab-produced meat does not carry any risk of disease. It also does not need to be treated with the antibiotics.

A study found that the lab-grown beef makes use of 45 percent less energy than average global representative figure for farming cattle. At the same time, it also produces 96 percent less greenhouse gas emissions. It requires 99 percent less land as well.

It is also important to note that the animal rights group called Peta, funded research in the United States so far and had also offered one million US dollar or 750000 euros prize for that lab which is capable to produce and bring out in-vitro chicken meat to the market.

A National Sample Survey Office (NSSO) study revealed in July 2013 that the Christians from the rural areas as well as the Sikhs from urban areas faced highest level of unemployment during 2009-2010, just a year after the global economic crisis. The study was conducted for a period from July 2009 to June 2010. This was the 66th round of National Sample Survey in order to find out about the employment and unemployment situation among major religious groups in India.

The survey studied the Unemployment Rate. The Rate of Unemployment, also known as Unemployment Rate is defined as the number of persons unemployed per 1000 in labour force. The survey covered 7402 villages as well as 5252 urban areas, thereby including 100957 households and 4.59 lakh people.

Major highlights of the Survey

• The National Sample Survey Office (NSSO) study unveiled that the rate of unemployment in rural India from July 2009 to June 2010 was less than that in the urban areas. This trend indicated that the economic crisis had major impact on the organised sector of urban areas than the rural areas.
• The 8th quinquennial survey on employment revealed that the rate of unemployment in rural areas was the highest among Christians (3 percent among men and 6 percent among women).
• In the urban areas, this rate of unemployment was highest among the Sikhs (6 percent among men and 8 percent among women).
• Among four categories of the workers, i.e., rural females, rural males, urban females and urban males; the urban females were the worst affected with 6 percent unemployment rate.
• The survey also revealed that maximum number of employed in the rural areas were those who were self-employed. 54 percent of males as well as 56 percent of females were found in this category of unemployed.
• As far as the rural male workers were concerned, the level of self employment was highest for the Sikhs (55 percent), followed by the Hindus (54 percent).
• Among the Christians in rural areas, 17 percent of male and 11 percent of female workers were regular wage or salaried employed.
• In the urban areas, most of the workers were almost equally involved in regular wage or salaried employed as well as in the category of self employment. The proportion of the workers in self employment category were highest among Muslims, followed by the Sikhs.
• In case of urban Christians, major portion of male workers (45 percent) and female workers (61 percent) were involved in regular wage or salaried employment.
• Among the urban Hindus, 44 percent of males as well as 40 percent of females belonged to regular wage or salaried employment category.
• The Worker Population Ratio (WPR) was higher among the male workers than among the female workers in all the religions. The difference was greater in the urban areas. The Worker Population Ratio (WPR) is the number of persons employed per 1000. The male-female differential in WPR was at its lowest among the Christians. WPR was highest among Christians in all categories covered by the survey, except among the urban males. Among the Urban Males, WPR of Hindus was higher.
• The survey also found that in the rural areas, majority of the male workers were from not literate category (28 percent) or the literate and up to primary category (28 percent). Majority of the female workers were from not literate category (59 percent). Proportion of the male workers with the general education level, i.e., secondary and above was highest among the Christians (32 percent) followed by the Sikhs (30 percent).

About the National Sample Survey

• The National Sample Survey is an all-India quinqueiinial survey on employment and unemployment in India, which was carried out during the period July 2009 to June 2010 as a part or the 66th round of the National Sample Survey (NSS).
• In the National Sample Survey, information on various facets of employment and unemployment in India, as well as the individual characteristics associated with household members such as age, level of general and technical education attained, current attendance in educational institutions as well as vocational training received was collected at the national and state level.
• Based on the entire data collected, estimates pertaining to employment and unemployment situation of people belonging to different religious groups in India with different characteristics were studied.
• The religions included Hinduism, Islam, Christianity, Sikhism and Others (Jainism, Buddhism and Zoroastrians).

Scientists identified 18 new genes responsible for driving glioblastoma multiforme, the most common and most aggressive form of brain cancer in adults. The team of scientists from Columbia used a combination of high throughput DNA sequencing and a new method of statistical analysis to generate a short list of driver candidates. The massive study of nearly 140 brain tumours sequenced the DNA and RNA of every gene in the tumours to identify all the mutations in each tumour.
A statistical algorithm was then used to identify the mutations most likely to be driver mutations. The algorithm differs from other techniques to distinguish drivers from other mutations in that it considers not only how often the gene is mutated in different tumours, but also the manner in which it is mutated.
The analysis identified 15 driver genes that had been previously identified in other studies - confirming the accuracy of the technique - and 18 new driver genes that had never been implicated in glioblastoma.
Significantly, some of the most important candidates among the 18 new genes, such as LZTR1 and delta catenin, were confirmed to be driver genes in laboratory studies involving cancer stem cells taken from human tumours and examined in culture, as well as after they had been implanted into mice.
The study found that half of about 15 percent of patients have tumours driven by a fusion between the gene EGFR and one of several other genes.
The fusion makes EGFR - a growth factor already implicated in cancer - hyperactive; hyperactive EGFR drives tumour growth in these glioblastomas.

Jeffrey P Bezos, the founder and Chief Executive Officer of Amazon on 5 August agreed to buy the newspaper assets of the Washington Post Company for 250 million US dollar. The decision to sell the assets was made following the fall in revenue and decline in the circulation of its copies.

The Washington Post has been owned by the Graham family for 80 years. Donald E. Graham is the Chairman and Chief Executive of Washington Post at present.   

Apart from this, the Boston Globe, one of the most prestigious newspapers in US was sold by New York Times Company to John Henry, the American billionaire owner of Liverpool Football Club for 70 million US dollar. Globe was launched in 1993 and broke the records of highest price ever paid to the American newspaper. One of the important reasons behind the sale was fall of the newspaper’s circulation to nearly half over a decade from 438621 copies to 230351 in September 2012.

Turkey on 6 August 2013 successfully completed a trial run of a rail tunnel under the Bosphorus Strait connecting Istanbul's European and Asian sides, the first of several planned mega projects in the country's largest city to see the light of day.

The 13.6 km (8.5 mile) tunnel, including a 1.4 km immersed tube tunnel is the deepest of its kind in the world at 56 metres. It passes under Turkey's Bosphorus Strait, the busy shipping channel linking the Marmara Sea to the Black Sea. The tunnel is part of a larger 5 billion US dollars Marmaray project which also includes an upgrade of existing suburban rail lines to create a 76 km line that according to the government will carry 1.5 million people a day across the city's two sides.

Construction on the tunnel began in 2004 by a Japanese-Turkish consortium, with funding coming from the Japan Bank for International Cooperation (JBIC) and the European Investment Bank (EIB).

The Marmaray, which has been beset by long delays, is now slated to open to the public on Oct. 29, the anniversary of modern Turkey's founding, making it the first of Istanbul's planned mega projects to be completed.
