Ocean surface warming is resulting in an expansion of stratified, low-nutrient environments, a process referred to as ocean desertification. A challenge for assessing the impact of these changes is the lack of robust baseline information on the biological communities that carry out marine photosynthesis.

While outlining strategies to increase availability of pulses at affordable prices, it is argued that increasing domestic production of pulses is the only option. Access to one or two protective irrigation sources during the growing season can lead to sizeable increases in pulse production. The har khet ko paani initiative should give priority to pulse-producing areas. The minimum support price, without procurement, helps traders more than farmers because it acts as a focal point for tacit collusion among traders.

India has far higher open defecation rates than other developing regions where people are poorer, literacy rates are lower, and water is relatively more scarce. In practice, government programmes in rural India have paid little attention in understanding why so many rural Indians defecate in the open rather than use affordable pit latrines. Drawing on new data, a study points out that widespread open defecation in rural India is on account of beliefs, values, and norms about purity, pollution, caste, and untouchability that cause people to reject affordable latrines.

Herbarium specimens may provide a record of past environmental conditions, including heavy metal pollution. To explore this potential, we compared concentrations of copper, lead, and zinc in historical and new collections from four sites in Rhode Island, USA.

Extreme ecosystems such as hot springs are of great interest as a source of novel extremophilic species, enzymes, metabolic functions for survival and biotechnological products. India harbors hundreds of hot springs, the majority of which are not yet explored and require comprehensive studies to unravel their unknown and untapped phylogenetic and functional diversity.

US government proposes introducing more wolves to Isle Royale as population dwindles.

Approximately 1.5 billion people worldwide are overweight or affected by obesity, and are at risk of developing type 2 diabetes, cardiovascular disease and related metabolic and inflammatory disturbances. Although the mechanisms linking adiposity to associated clinical conditions are poorly understood, recent studies suggest that adiposity may influence DNA methylation, a key regulator of gene expression and molecular phenotype.

The West Antarctic Ice Sheet is one of the largest potential sources of rising sea levels. Over the past 40 years, glaciers flowing into the Amundsen Sea sector of the ice sheet have thinned at an accelerating rate, and several numerical models suggest that unstable and irreversible retreat of the grounding line—which marks the boundary between grounded ice and floating ice shelf—is underway.

Researchers brave polar bears, mosquitoes and gull attacks in the Canadian Arctic to investigate an alarming die off.

Leaving the European Union is not yet a done deal, and UK researchers must look past a pay-off and take a stand.
