Agriculture: A loan for lean season

For farmers in rural Zambia, payday comes just once a year, at harvest time. This fact impacts nearly every aspect of their lives, but until now researchers hadn’t realized the true extent.

Consequences of glacier shrinkage

Scientists have investigated the causes of a glacial lake outburst flood in the Ladakh region of India. They drew on field surveys and satellite images to create an inventory of glacial lakes for the Trans-Himalayan region of Ladakh, identifying changes in the size and number of glacial lakes, including undocumented outburst floods. The inventory aims to improve risk assessment for future events.

Discovery adds new species a lab’s ghoulish insect menagerie

A horrifying insect soap opera with vampires, mummies and infant-eating parasites plays out on the stems and leaves of oak trees every day, and an evolutionary biologist found the latest player, a new species of predatory wasp, within walking distance of his lab.

Obesity and disease tied to dramatic dietary changes

The ‘mismatch hypothesis’ argues that our bodies evolved to digest the foods that our ancestors ate, and that human bodies will struggle and largely fail to metabolize a radically new set of foods. This intuitive idea is hard to test directly, but the Turkana, a pastoralist population in remote Kenya, present a natural experiment: genetically homogenous populations whose diets stretch across a lifestyle gradient from relatively ‘matched’ to extremely ‘mismatched’ with their recent evolutionary history.

Onions are so ubiquitous on people’s plates that fluctuations in the tuber’s prices can make or break electoral fortunes; cultivators of the bulb, however, seem to be perenially at the receiving end. Now, as a government move to allow imports threaten to replay their tragedy as a farce, here’s our take on just how much can you peel off the humble vegetable.

Oldest securely dated evidence for a river flowing through the Thar Desert, Western India

(Max Planck Institute for the Science of Human History) Using luminescence dating of ancient river sediments, a new study published in Quaternary Science Reviews presents evidence for river activity at Nal Quarry in the central Thar Desert starting from approx. 173 thousand years ago. These findings represent the oldest directly dated phase of river activity in the region and indicate Stone Age populations lived in a distinctly different Thar Desert landscape than we encounter today.
