Too much light at night may quietly reshape your heart

Nighttime light exposure was linked to thicker, stiffer heart chambers and early signs of reduced heart function in a study of more than 11,000 people. The findings suggest that keeping bedrooms darker could be an overlooked strategy for protecting the heart.

Life on the East Asian Flyway – Part Two: Yellow Sea South

Ann Jones flies north to Shanghai as shorebirds from as far away as Australia, Indonesia, Thailand, Myanmar and Bangladesh arrive on the coast of the Yellow Sea. Here she meets a traditional whistling bird hunter who used to catch shorebirds for the pot but now does it for science. Bird mimic Mr Jin Weiguo demonstrates his centuries-old technique of bird trapping - luring them into nets by copying the different calls of the many different species. Scientists can then attach ID rings and GPS transmitters to follow their migration and estimate their declining numbers. In ten years as a conservation trapper, Mr Jin has caught more than 10,000 birds.In Jiangsu province to the north of Shanghai, Ann also spots the world’s smallest and most endangered shorebird – the remarkable spoon-billed sandpiper. This species is regarded as the Panda of migratory shorebirds – a charismatic flagship species for the protection of the rapidly disappearing mudflats on which all the migratory shorebirds and local fisher folk depend. Ann meets the Shanghai birders who set up an NGO to save the most important surviving locations for this bird’s crucial spring and autumn breaks in the Yellow Sea. One 7km stretch of coast, known as Tiaozini, hosts at least 50% of the world’s spoon-billed sandpiper population, which after a precipitous decline now numbers about 200 breeding pairs. Tiaozini is now recognised worldwide as a critical place for the species’ survival. The provincial government has advanced plans to convert Tiaozini into dry land within five years.Additional recordings in this programme were provided by the Macaulay Library of Natural Sounds at the Cornell Lab of Ornithology.Producer: Andrew Luck-BakerThe series is a co-production from the BBC World Service and Australian ABC Radio Nati

The Return to Mawson's Antarctica - Part One

Join the scientists of the Australasian Antarctic Expedition 2013, as they go about their experiments and seek adventure at the windiest place on earth.This location was named the Land of Blizzard by Douglas Mawson, the Antarctic pioneer who was the first to explore this remote and desolate place 100 years ago.Between 1911 and 1914, Douglas Mawson explored a fiercely harsh part of Antarctica while the more celebrated Scott and Amundsen raced to the South Pole, elsewhere on the frozen continent. Mawson’s expedition was dedicated to scientific study in the early Heroic Age of Antarctic Exploration but his journey was fraught with horror and danger. The 2013 Australasian Antarctic Expedition aims to repeat many of Mawson’s investigations around Commonwealth Bay and Cape Denison in East Antarctica where the original team set up their base. This remote area hasn’t been studied systematically for 100 years, so the expedition will reveal any changes that have taken place as a result of climate change.

Self-Healing Materials

Quentin Cooper takes a look at the new materials that can mend themselves. Researchers are currently developing bacteria in concrete which, once awakened, excrete lime to fill any cracks. In South America you can choose a car paint that heals its own scratches. And there are even gold atoms which can migrate to mend tiny breaks in jet turbine blades.Engineers normally design things so the likelihood of breaking is minimised. But by embracing the inevitability of breakage, a new class of materials which can mend cracks and fissures before you can see them may extend the lives of our cars, engines, buildings and aeroplanes far beyond current capability.(Image: Presenter, Quentin Cooper, BBC Copyright)
