How the elusive otter has made its home in Goa’s mangroves

Human-dominated mangroves are far from what is considered an ideal environment for otters. And yet this estuarine island on India’s western coast is home to a thriving population of the threatened smooth-coated otter (Lutrogale perspicillata). Recent studies of this elusive species living in the brackish waters of Chorao island—far from the freshwater sources that otters are typically believed to rely on—offer new insights into otter behaviour that could inform future conservation efforts.

Bird immune systems reveal harshness of city life

They may peck greedily at feeding tables – and have it easier than country birds do in the warmer urban winters – but city birds, it turns out, are in turmoil on the inside. By Aisling Irwin Researchers have found that many internal defence mechanisms that are quiet in rural birds are much more active in those in cities. These biological pathways are pumping out extra antioxidants, immune system cells and detoxifiers – a sign that urban life is challenging their health. Globally, bird numbers are dropping. According to figures published by conservation organisation BirdLife International last year, 40% of bird species have

Storing CO2 underground can curb carbon emissions, but is it safe?

At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public. By Jonathan O’Callaghan This approach is known as carbon capture and storage (CCS) and it’s been around for decades but has never really taken off. In its recent reports, however, the UN Intergovernmental Panel on Climate Change (IPCC) said that CCS could have a key role to play if we’re going to meet our climate
