Earth's first example of recycling -- its own crust!
March 17, 2017 07:22 AM - Carnegie Institute for Science
Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from Carnegie’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.
Eating healthier food could reduce greenhouse gas emissions
March 16, 2017 06:59 AM - Julie Cohen, UC Santa Barbara
You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.
What makes farmers try new practices?
March 15, 2017 07:27 AM - University of Illinois at Urbana-Champaign
Change is never easy. But when it comes to adopting new agricultural practices, some farmers are easier to convince than others.
Spiders Eat 400-800 Million Tons of Prey Every Year
March 14, 2017 11:13 AM - University of Basel
It has long been suspected that spiders are one of the most important groups of predators of insects. Zoologists at the University of Basel and Lund University in Sweden have now shown just how true this is – spiders kill astronomical numbers of insects on a global scale. The scientific journal The Science of Nature has published the results.
New Study Helps Explain How Garbage Patches Form in the World's Oceans
February 24, 2017 06:40 AM - University of Miami
A new study on how ocean currents transport floating marine debris is helping to explain how garbage patches form in the world’s oceans.
Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and colleagues developed a mathematical model that simulates the motion of small spherical objects floating at the ocean surface.
Fifth of food lost to over-eating and waste
February 22, 2017 07:00 AM - University of Edinburgh
Almost 20 per cent of the food made available to consumers is lost through over-eating or waste, a study suggests.
The world population consumes around 10 per cent more food than it needs, while almost nine per cent is thrown away or left to spoil, researchers say.
Efforts to reduce the billions of tonnes lost could improve global food security – ensuring everyone has access to a safe, affordable, nutritious diet – and help prevent damage to the environment, the team says.
E-Waste in East and South-East Asia Jumps 63% in Five Years
January 15, 2017 03:33 PM - United Nations University
The volume of discarded electronics in East and South-East Asia jumped almost two-thirds between 2010 and 2015, and e-waste generation is growing fast in both total volume and per capita measures, new UNU research shows.
Driven by rising incomes and high demand for new gadgets and appliances, the average increase in e-waste across all 12 countries and areas analysed — Cambodia, China, Hong Kong, Indonesia, Japan, Malaysia, the Philippines, Singapore, South Korea, Taiwan, Province of China, Thailand and Vietnam — was 63% in the five years ending in 2015 and totalled 12.3 million tonnes, a weight 2.4 times that of the Great Pyramid of Giza.
Global climate target could net additional six million tons of fish annually
December 24, 2016 07:50 AM - University of British Columbia
If countries abide by the Paris Agreement global warming target of 1.5 degrees Celsius, potential fish catches could increase by six million metric tons per year, according to a new study published in Science.
The researchers also found that some oceans are more sensitive to changes in temperature and will have substantially larger gains from achieving the Paris Agreement.
Could Rudolph and friends help to slow down our warming climate?
December 22, 2016 07:19 AM - IOP Publishing
Reindeer may be best known for pulling Santa’s sleigh, but a new study suggests they may have a part to play in slowing down climate change too.
A team of researchers, writing in the journal Environmental Research Letters, found that when reindeer reduce the height and abundance of shrubs on the Arctic tundra through grazing, the level of surface albedo – the amount of solar energy (shortwave radiation) reflected by the Earth back into space – is increased.
Rudolph's antlers inspire next generation of unbreakable materials
December 21, 2016 07:21 AM - Queen Mary University of London
The team looked at the antler structure at the 'nano-level', which is incredibly small, almost one thousandth of the thickness of a hair strand, and were able to identify the mechanisms at work, using state-of-the-art computer modelling and x-ray techniques.
First author Paolino De Falco from QMUL's School of Engineering and Materials Science said: "The fibrils that make up the antler are staggered rather than in line with each other. This allows them to absorb the energy from the impact of a clash during a fight."
