Changes in forest carbon stocks are a determinant of the regional carbon budget. In the past several decades, China has experienced a pronounced increase in forest area and density. However, few comprehensive analyses have been conducted.
In the first hours of March's accident at the Fukushima Daiichi nuclear power plant, workers rushed to flood three damaged reactors with sea water to prevent a catastrophic meltdown. Three months later, water is still being pumped into the cores and has become the biggest obstacle to cleaning up the site.
The causes and timing of tropical glacier fluctuations during the Holocene epoch (10,000 years ago to present) are poorly understood. Yet constraining their sensitivity to changes in climate is important, as these glaciers are both sensitive indicators of climate change and serve as water reservoirs for highland regions.
Hourly rainfall data recorded at 72 Self Recording Raingauge Stations (SRRG) for the period 1969–2006 are utilized to study the characteristic features of hourly rainfall and diurnal variations of rainfall in India. Temporal changes in the short duration (less than 12 h) rainfall extremes are examined. Time distribution of a heavy rain spell of 24 h duration, which is an important component in water resources management and flood control studies, is analysed.
Centre approves field trials of 14 GM crops. But some states refuse trials, saying safety regulations are too lax. With politicians joining activists, the issue is likely to take a politically volatile turn. This special report in DTE uncovers the mess in GM crops.

Sports and energy drinks are being marketed to children and adolescents for a wide variety of inappropriate uses. Sports drinks and energy drinks are significantly different products, and the terms should not be used interchangeably.
The emergence and rapid global spread of the swine-origin H1N1/09 pandemic influenza A virus in humans underscores the importance of swine populations as reservoirs for genetically diverse influenza viruses with the potential to infect humans. However, despite their significance for animal and human health, relatively little is known about the phylogeography of swine influenza viruses in the United States.
The objective of the study was to estimate prevalence of overweight and obesity in apparently healthy children from five zones of India in the age group of 2 to 17 years and to examine trends in body mass index (BMI) during the last two decades with respect to published growth data.
