Japan's ongoing nuclear emergency has intensified discussion on a simmering issue: the potential cancer risk from living near a reactor that is operating normally.
It came as no surprise when the Tokyo Electric Power Company (TEPCO) admitted last week that it will scrap its stricken Fukushima Daiichi reactors. After explosions, copious radioisotope leaks and a liberal dousing with sea water, the reactors are a write-off. But what will workers encounter when they finally start decommissioning the shattered plant?
Even as the damaged reactors at the Fukushima Daiichi nuclear power station continue to leak radiation, researchers have begun laying the groundwork for studies that will look for any long-term effects on public health.
Counting wildlife is no easy matter, especially with a wide-ranging and stealthy forest dweller like the tiger, which is in the spotlight this week. On 28 March, India announced that its tiger population, in decline for decades, has increased by 225 animals over the past four years, to a total of 1,706. The scale of the increase is open to dispute, but the announcement signals a welcome development: the beginnings of a more rigorous approach to counting the big cats. (Editorial)
Large swathes of the Brazilian Amazon have come to resemble the midwestern United States in recent years, having been planted with soya as far as the eye can see. This development has unnerved conservation organizations, which fear that huge expanses of pristine rainforest are being felled to make way for the lucrative crop. A widespread hope is that large agribusiness, aware of both the need to protect this fragile environment and the importance of good public relations, can be induced to farm more sustainably.
Recently, the Stockholm Convention prohibited the use of toxaphene and has been reviewing endosulfan. The historical use of these pesticides may contaminate food and tend to accumulate in the food chain.
The objective of the study was to evaluate the effect of iron and zinc
deficiency on short term memory of children in the age group of 6-11 years and to assess the response to supplementation therapy.
During the years prior to the turn of the century, scientific and medical attention for genetic disorders was mainly focused on understanding rare single-gene disorders, such as Huntington's disease, Duchenne muscular dystrophy, and cystic fibrosis (CF), as well as chromosomal abnormalities. The medical specialty of clinical genetics was established in the 1980s and 1990s in many European countries to diagnose these kinds of rare disorders and to counsel patients and families.
Human actions rather than natural forces are the source of most contemporary changes in the state and flows of the biosphere. Understanding these actions and the social forces that drive them is crucial to understanding, modelling and predicting local, regional as well as global environmental change and also for managing and responding to such change. The present study investigates the patterns of urban land transformation in Srinagar City, which lies in fragile hill eco-system of Kashmir valley. The results points towards unplanned and haphazard urban expansion and transformation.
