Exercise doesn't seem to ease anxiety, depression


Exercise doesn't seem to ease anxiety or depression, says a recent study conducted in the Netherlands among twins, one of whom exercised, while the other didn't.

Marleen HM De Moor of VU University Amsterdam and colleagues studied 5,952 twins from the Netherlands Twin Register, along with 1,357 additional siblings and 1,249 parents.

Participants, aged between 18 and 50, filled out surveys about leisure-time exercise and completed four scales measuring anxious and depressive symptoms.

Associations observed between exercise and anxious and depressive symptoms "were small and were best explained by common genetic factors with opposite effects on exercise behaviour and symptoms of anxiety and depression," the authors note.

"In genetically identical twin pairs, the twin who exercised more did not display fewer anxious and depressive symptoms than the co-twin who exercised less."

Exercise behaviour in one identical twin predicted anxious and depressive symptoms in the other, meaning that if one twin exercised more, the other tended to have fewer symptoms.

However, the same was not true of dizygotic (fraternal) twins or other siblings, who share only part of their genetic material.

In addition, analyses over time showed that individuals who increased their level of exercise did not experience a decrease in anxious and depressive symptoms.

The results do not mean that exercise cannot benefit those with anxiety or depression, the authors noted, only that additional trials would be needed to justify this type of therapy.

US financial crisis: West`s loss is India`s gain


St Petersburg, June 08: The Western financial crisis means the fast-growing economies of Brazil, Russia, India and China will grow their share of the world economy even faster than originally forecast, the founder of the four-nation BRIC concept said.

The term BRIC was coined by Wall Street bank Goldman Sachs to describe how the four rising economies are likely to rival and overtake many of the West`s leading economies over the next half century.

Jim O`Neill, the Goldman Sachs economist who originated the term in 2003, said the financial crisis that began in US mortgage security markets was allowing the BRIC countries to take a bigger share of world gross domestic product.

"On a relative basis it definitely allows the BRICs to develop faster as they are going to take an even bigger share of GDP sooner," O`Neill told a news agency in an interview at an economic forum in Russia`s former imperial capital of St Petersburg.

"This is a financial crisis of the West and we must not forget that of the world`s six billion people most of them are not affected by this," he said. "I was in India four weeks ago and there were no signs of India being affected by all of this."

O`Neill, head of global economic research at Goldman, said China, India and Russia were actually growing faster than originally predicted by his research.

"Of the four BRICs, Russia, China and India have all grown on average two percent more than we suggested," he said. "It is a hell of a lot so they are now collectively 16 percent of global GDP so it is all happening a lot quicker."

The four BRIC countries have been seeking to form a political club to convert their growing economic power into greater geopolitical clout.

Last month in the Russian city of Yekaterinburg, the four sought to formalize their club at the first stand-alone meeting of BRIC Foreign Ministers.

"I would hope that Western leaders take note of that meeting and start to accelerate bringing them into the G8 club and the IMF because the world doesn`t want a separate club just looking after the growing countries the same as it doesn`t need an old club looking after the declining -- it needs a better club involving them both," O`Neill said.

"I think that the lack of progress by the G8 and the Western leaders to change is really bad and is one of the biggest problems in the world today," he said.

O`Neill says the combined GDP of the BRIC countries could overtake the combined economic might of the G7.

Detractors say optimistic predictions about the BRIC economies ignore major hurdles to their development such as future political instability, rampant corruption and decrepit infrastructure.

Economists repeatedly forecast in the 1950s and 1960s that Brazil would become one of the world`s top economic powers, only for its once-rapid growth to stall dramatically in the debt crisis of the 1980s and to stagnate throughout the 1990s.

Russian President Dmitry Medvedev has said Russia will become one of the top five economies of the world by 2020, but admits the rule of law needs to be strengthened and corruption has to be rooted out.

O`Neill said Russia should speed up some of its infrastructure projects and that corruption could sap Russia`s economic potential.

"At the core of it is a stronger self-confidence in a rule of law that everybody likes," he said. "In some ways Russia enjoys stability almost too much.”

"The Russian people like stability which given Russia`s history is very understandable and admirable but it should not come at the expense of things which are needed for private sector risk-taking, which are stronger property rights and a stronger rule of law."

Search for water in Martian soil

London, June 07: NASA`s Phoenix Mars Lander, which touched down on the surface of the Red Planet on May 2 has begin testing Martian soil for traces of water.

After two test scoops at a site nicknamed ‘Dodo,` the spacecraft successfully grabbed its first real shovelful of Martian soil on June 6.

The new sample, pulled from a neighbouring patch of ground dubbed ‘Baby Bear`, shows signs of a mysterious white substance – thought to be ice or salt – that had been seen in the practice digs.

The lander`s arm is now poised above the Thermal and Evolved-Gas Analyzer (TEGA) compartments, which will heat up the soil and test the resulting vapours for water and other components.

“This is really an important occasion for us, to be poised to make a measurement for the first time of the polar soils that`ll tell us how much water is in the soil,” chief scientist Peter Smith of the University of Arizona in Tucson, US.

TEGA will also test for organic molecules, as well as minerals that might have been shaped by water.

Because TEGA has only eight ovens for analysis, each of which can be used only one time, arm operators wanted to make sure they got just the right amount of soil – enough to guarantee some would fall into the pencil lead-sized opening to the oven, but not so much as to accidentally drop some onto other parts of the instrument.

“We`re ecstatic that we got a third to a quarter of a scoopful, roughly the size of a cup. We couldn`t be happier,” said robotic arm flight software lead Matt Robinson of the Jet Propulsion Laboratory in Pasadena, California, US.

According to Smith, the first results from the TEGA tests will come in over the coming week.

Phoenix will also deliver another sample to the lander`s optical microscope as well as to the wet chemistry lab, which can test for components like salt.

The team may also return the robotic arm to Dodo, where the arm will dig down farther to look for a layer of ice in the soil.

India improves power capacity in 2007


Indo-Asian News ServiceSaturday, December 29, 2007 (New Delhi):India added a total of 9,050 MW power generation capacity this year between January 1 and December 14 - 8 per cent below the country's electricity requirement, the power ministry said.This includes 6,645 MW of thermal, 2,185 MW hydro and 220 MW of nuclear power, the ministry said in a yearend statement on its performance.In the same period, 33 more power projects with 21,424 MW generation capacity were taken up for implementation, the ministry said on Friday.This comprises 21 thermal and 12 hydropower projects with capacities of 17,634 MW and 3,790 MW respectively, the statement added.India produces a total of 138,251 MW of electricity. Of this, thermal power accounts for 89,275 MW, hydro 34,680 MW, nuclear 4,120 MW, and renewable sources for 10,175 MW, according to latest statistics available with the ministry.India must add 73,000 MW power generation capacity by March 2012 if it is to meet the growing electricity demand-supply gap.

Survey: India upbeat in business

Sunday, December 30, 2007 (New Delhi):Riding on expectations of higher growth, increased inventory levels and greater employment generation, business confidence for the period starting October till end of the current fiscal is upbeat, says a survey by a leading Indian industry chamber.This is much higher than the same survey conducted for the period April-September 2007-08, the survey by the Confederation of Indian Industry (CII) indicated.The CII business confidence index (CII-BCI) showed the current situation index (CSI) and expectations index (EI) was higher among non-manufacturing firms as compared to manufacturing firms.As many as 59 per cent of the respondents indicated the gross domestic product (GDP) growth rate to be around 9 per cent, while 22 per cent indicated 9 to 9.5 per cent.About 87 per cent of firms expressed plans to increase investment during October March 2007-08 and 59 per cent have revealed capacity utilization in the range of 75 to 100 per cent."While expectations on capacity utilisation are normal, inventory levels are on higher side," CII said in a statement.A large number of firms also expressed their decision to increase the value of production. About 66 per cent of the companies surveyed have already increased their scale of production during the first half of 2007-08.All these are expected to generate considerable employment by the second half of the upcoming financial year.Despite a surging rupee against the weakening dollar, exports would continue to increase. However, the sector continues to face procedural delays, which acts as long-standing hurdle for exporters, which raises transactions costs and needs to be addressed urgently, the chamber said.
