Its the common notion that forests remove carbon dioxide from the air and prevent global warming . But it has some falacies according to a new study. There's a kind of forest that does remove carbon dioxide, but does not help prevent global warming because it heats up so much itself. Forests can directly absorb and retain heat, and, in at least one type of forest, these effects may be strong enough to cancel out a good part of the benefit in lowered carbon dioxide, says a discovery by chemistry researchers at the Weizmann Institute (WI), Israel.
For the past 10 years, WI has been operating a research station in the semi-arid Yatir Forest, a pine forest at the edge of the Negev Desert. This station is part of a worldwide project comprising over 400 stations, called FLUXNET, which probes the link among forests, the atmosphere and climate around the globe. Forests counteract the greenhouse effect by removing heat-trapping carbon dioxide from the atmosphere and storing it in living trees. Over the years of measurement, Yakir's group has found that the semi-arid forest, even though not as luxuriant as temperate forests farther north, is a surprisingly good carbon sink - better than most European pine forests and about on par with the global average. This was unexpected news for a forest sitting at the edge of a desert, and it indicated that there is real hope for the more temperate forests if things heat up under future global change scenarios. But forests do more than just store carbon dioxide, and Yakir, together with Eyal Rotenberg, decided to look at the larger picture - the 'total energy budget' of a semi-arid forest. The first hint they had that other processes might be counteracting the cooling effect of carbon dioxide uptake came when they compared the forest's albedo - how much sunlight is reflected from its surface back into space - with that of the nearby open shrub land. They found that the dark forest canopy had a much lower albedo, absorbing quite a bit more of the sun's energy than the pale, reflective surface of surrounding area. In a cloudless environment with high levels of solar radiation, albedo becomes an important factor in surface heating.

Global Warming- Is It Really As Dangeous As Campaigned, Dangers of Gobal Warming- Are They Over Emphasized
Andy Pitman, an Australian scientist (co-authour the controversial climate change report) tried to defend the errors found in it. He said that one or two mistakes does not undermine the case of global warming. Andy Pitman, co-director of University of NSW climate change research centre and key author of the IPCC's 2001 and 2007 reports, said that there might be two paragraphs that have been questioned in a 1600-page document but there are the other 1599 pages that nobody has found any problems with. The prediction that Himalayan glaciers could disappear by 2035 has now been shown to be unfounded but Pitman said while the date may be wrong the outcome will be the same. Its not that the Himalayan glaciers are not vulnerable to climate change or are not melting or are not melting at an accelerated rate. It is the date of 2035 that is a bit doubtful. What is more worrying to Prof Pitman is the revelation that the IPCC chairman Rajendra Pachauri may have benefited from the errors by receiving funding for his research institute. This is yet another blow for climate scientists and Pitman said it will give climate change sceptics ammunition to continue their attacks. It's very clear that increased CO2 and other greenhouse gases are causing climate change but it certainly wont stop the sceptics using the information for their own purpose. Pitman said he believed concerted efforts by sceptics to attack and misinform the community are working, very similar to the efforts of tobacco lobbyists who deny the health effects of smoking. If climate scientists losethe fight with the sceptics , it will be the most unfortunate thing to the future of mankind.

There is no stopping for Deepika Padukone. Her debut with Khan ('Om Shanti Om') was a super success.. And she's scored a winner with another Khan (Saif Ali Khan) in the second most successful film of 2009. But Deepika Padukone is fr from contended. She's set her sights on two other desirable Khans too. I'd love to work with Salman Khan and Aamir Khan too exclaims Deepika. Fresh from the break-up with Ranbir Kapoor, the actress has plunged herself deep into her career. Besides, the thumping win and the critical acclaim for her work in 'Love Aaj Kal' has helped her to get some super duper assignments. High on that list is director Ashutosh Gowarikar's 'Khelein Hum Jee Jaan Se' with Abhishek Bachchan as co star. Enacting a revolutionary in Gowariker's film, buzz has it that DP is likely to walk away with all the top acting honours, once again. Besides, she will also be found in a bikini with Akshay Kumar in 'Houseful' and pair up with Neil Nitin Mukesh in Pradeep Sarkar's next. 'Karthik Calling Karthik' waiting to hit the movie plexes soon. It could well be success calling Deepika ….

Global research firm Gartner Inc. has predicted that worldwide IT spending would rise 4.6 percent to $3.4 trillion in 2010, on the back of an economic recovery and a declining dollar. In 2009, spending on information technology fell 4.6 percent to $3.22 trillion, the firm said in a note. Much of the increase in 2010 forecast could be attributed to a projected decline in the value of the U.S. dollar compared to 2009. All major segments such as computer hardware, software, IT services would contribute to the growth, with emerging markets leading the recovery. Recovery in western Europe, the United States and Japan is expected to start more slowly than the emerging markets of Latin America, the Middle East, Africa and Asia Pacific. Although recovery will be slow, over the next 12 to 18 months, gross domestic product is projected to increase, consumer confidence is expected to improve, and the availability of credit should increase. At the same time, demand for new technologies will be released as enterprises focus on new growth opportunities and increase spending plans. Leading Indian software services companies Tata Consultancy Services, Infosys Technologies and Wipro published quarterly forecasts and indicated a recovery in the global economy was boosting demand for outsourcing which on the other hand is good for Indian economy also!
A data security firm has published the commonly used passwords on the net.
Imperva analysed around 32 million passwords that had been exposed in a recent hack of the RockYou website. Last year a hacker had breached the site's company database, gaining access to the usernames and passwords of all its 32 million users. Now, after studying the breach, the firm has come up with a list of the commonly used passwords which one should avoid. Everyone needs to understand that with minimal effort, a hacker can gain access to a new account every second-or 1000 accounts every 17 minutes said Amichai Shulman, Imperva's chief technical officer. People using the same passwords on Facebook and Twitters that they use in the workplace bringing the possibility of compromising the security of theenterprise specially if they are using easy to crack passwords like '123456. So it's high time for everyone of us to take password security seriously; as it's an important first step in data security.
The most commonly used passwords analysed in the study were:

A team of scientists has carried out a research regarding the changes in the surface temperatures in the Indian Ocean and its possible relationship with global warming. The research was done by Nobuko Nakamura and his team from the University of Tokyo, along with Timothy R. McClanahan from Wildlife Conservation Society, and Swadhin K. Behera from the Frontier Research Center for Global Change, Yokohama, Japan. Recently, the temperature variation has become a major determining factor on the weather variations in the Indian Ocean region. Abnormally warm sea surface temperatures in the western Indian Ocean are accompanied by severe droughts over the Indonesian region and heavy rainfall over east Africa. To learn more about the effect of global warming on the climatic change in the Indian Ocean Region , the team of scientists studied a 115-year coral record from Kenya. They analyzed coral oxygen isotope ratios, which trace rainfall anomalies too. The results add to the evidence that the temperature variation has been occurring more frequently in recent decades. The researchers suggested that global warming effects on the western Indian Ocean have driven the observed shift in temperature variability and this changes ultimately lead to adverse climatic events like drought, heavy rainfall or fierce cyclonic weather . The results of the research and the recomendations have been discussed in the international conferrence at Copenhagen occured at december 2009.(ANI)

The economic crisis of 2008-09 is coming to an end. The job market is opening up and companies are loosening controls imposed on recruitment, training expenses and salary hikes. HR consulting firms FE spoke to said the calendar year 2010 looks hopeful not only on the hiring front, but for salaries and bonuses as well. However, companies will continue to remain conservative on salary hikes across the board. The exorbitant salaries and huge bonuses for people at the top management level, which saw a dip of about 25-30% in their cost to company (CTC) during the slowdown, could go up by 15-20% in 2010. This will include managing directors, chief executives, chief financial officers, senior vice-presidents and executive directors. In percentage terms, the total package might not move up significantly, but other benefits like perks and variable pay are expected to increase. Moreover, huge bonuses of about 80-100% will now shrink to 30-50%. The top-level salary in the BFSI (banking, financial services and insurance) sector at present is more than Rs 1 crore per annum compared with more than Rs 2-3 crore in the beginning of 2008. In the manufacturing and engineering sectors, it is still lower at around Rs 80 lakh, compared with Rs 1 crore earlier. IT/ITeS, which took the maximum hit during the downturn, is ready to give salaries in the range of Rs 1.5 to Rs 5 crore. Pharmaceutical sector is still lower by 10-15% against the 2008 levels. Salary at the top level in this sector is between Rs 75 and 80 lakh per annum. In the media sector, current salaries at the top level are more than Rs 1 crore, whereas, for retail and real estate sector, salaries might go up from Rs 75 lakhs and Rs 1 crore, respectively, per annum . But will this salary hike ia a true reflection of our economic growth? Opinions differ in this matter!
