Coastal areas around South East Asia suffer the most from pollution caused by ship traffic, according to a global study that estimates shipping emissions based on real-time, local activity for the first time. The study, published in Atmospheric Environment, sheds light on forces at play in a region where shipping pollution is believed to cause up to 24,000 deaths a year.
A combination of rusty water and stainless steel taps, or faucets, can put people at risk of life-threatening legionnaires’ disease. It seems that the protective coating on stainless steel fixtures – currently a firm favourite for kitchen and bathroom sinks – can degrade over time, encouraging the growth of Legionella species.
Simple mud concrete bricks provide the most affordable and sustainable houses in the tropics, a Sri-Lankan study suggests. Comparisons of four different types of walling materials revealed that mud concrete bricks have the lowest environmental impact and keep houses cool. They are also the cheapest, and easiest to dispose of once a house is knocked down.
Living near a noisy road seems to affect couples who are trying get pregnant, increasing the likelihood that it will take them between six to 12 months. That’s according to an analysis of 65,000 women living in Denmark.
The US Marine Mammal Commission, an organisation charged with restoring mammal populations in the world’s oceans, is set for the chop in president Donald Trump’s latest budget proposal.
Researchers in Romania are stepping up protests against controversial government science reforms. Hundreds of scientists at leading research institutions say they will refuse to sit on national panels that assess and award grants, after the Romanian researchers’ association Ad Astra called for the boycott on 30 May. But not all scientists in the country support the move.
Advances made in the energy efficiency of heating and transport are lost because of people’s desire to have bigger houses and cars, two research papers have shown. Researchers have found that houses in England, Australia, Canada, the US and New Zealand are getting bigger as people want more space and extra rooms. This means there is more air to be heated, destroying any climate benefits gained by better heating systems and more efficient insulation, they say.
Climate change could reduce the amount of carbon stored in soil in the Mediterranean region by a third over the next 60 years, according to research undertaken at the University of Cordoba. This in turn could drive up food prices and endanger crop production in the region as soils become poorer and more and more fertiliser is needed to keep yields up.
An eye-tracking study reveals that stress levels affect how much attention people pay to climate change imagery, even if they are supportive of environmental issues.
