Gut microbes can cause severe malnutrition
@singh_jyotsna Issue Date: Feb 1, 2013
A study of young twins in Malawi in south eastern Africa reveals that simple food intake will not improve the health of some of the world’s malnourished children. Their health depends more on the kind of microbes that inhabit their guts, the study shows. Understanding the role of the gut microbiota in under-nutrition could help devise new ecologically inspired strategies for correcting this problem.

Two decades of hope
Issue Date: May 15, 2012
When planning Down To Earth as a news magazine, we had two concerns: One, are we fully aware of the rapid changes that are taking place in the world’s technological systems, the kinds of opportunities and problems that these changes are likely to generate, and are we debating enough which of these we want to adopt or letting ourselves through inertia be swept
Uncertainty of conservation science
Issue Date: Apr 30, 2012
The conservation of endangered species is a venture marked by ambiguity. Whether the right populations are being protected from the appropriate threats to the precise degree, is a question that governments and conservationists are constantly evaluating. In such times of uncertainty, decision makers often turn to science for the answers.
Miles to go
Issue Date: Jun 30, 2005
For India, space is not the final frontier to be conquered. The country’s performance in solving mundane problems such as poverty, illiteracy and malnutrition may be dismal, but its space programme is soaring high. Its latest achievement: the May 5, 2005, launch of Cartosat-1, a satellite for mapmaking, with a 2.5 metre resolution. The 1,560 kilogramme (kg) Cartosat is the only satellite in the world with two panchromatic cameras positioned so as to measure even the elevation of the terrain mapped, allowing almost instant generation of 3-dimensional maps.
