Statistically, humanity is almost certainly responsible for global warming

The world is getting warmer, with 13 out of the 15 warmest years on record occurring in the current century. But just how sure are we that humanity's burning of oil and coal is the key factor in the temperature increase? A new project, led by researchers at the Potsdam Institute for Climate Impact Research, has answered that very question, working to estimate the likelihood of those temperature trends occurring naturally.Read More

Plant openings signal "birth of large-scale solar in Australia"

According to the Energy Supply Association of Australia, Australia boasts the highest rate of household solar panel installation in the world. But despite much of the continent being seemingly perfect for large scale solar, it has been slow in coming to the sun-drenched country. That could be set to change with the official opening of two plants that AGL Energy managing director and CEO Andy Vesey says "signals the birth of large-scale solar in Australia".

Giant clams could inspire better color displays and solar cells

Researchers from the University of California at Santa Barbara have discovered that giant clams may hold the key to improving solar cells and color displays. The new findings indicate that at least two species of giant clams produce a white coloration by combining red, green and blue light, in a manner similar to what occurs in television and smartphone displays.Read More

Breaking down humanity's contribution to climate change

Over the past 100 years, global temperatures have risen by an average amount of 0.8° C (1.4° F), which according to the Intergovernmental Panel on Climate Change (IPCC), is due largely to humanity's release of pollutants into the atmosphere. Now an international team of researchers has analyzed almost 40 years worth of data in order to quantify exactly what fraction of the change can be attributed to mankind based on events and trends in different regions.Read More

"Light recycling" tech could save incandescent bulbs from obsolescence

Incandescent light bulbs may put out a warmer-looking, more familiar type of light than LEDs or compact fluorescents, but they're far less efficient – the majority of the energy they use is wasted, mainly in the form of heat. Technology may save them yet, however. Scientists at MIT and Purdue University have developed an ultra-efficient new incandescent bulb that reuses the heat it gives off, converting that heat into more light.Read More

Air-purifying filter made from peanut shells

There are a lot of peanuts grown in Mexico. Needless to say, the processing of them results in a lot of discarded peanut shells, which are generally considered to be a worthless byproduct. That could be about to change, however. Led by biotech expert Raul Pineda Olmedo, a team from the National University of Mexico and the Research Center of Advanced Studies has developed an air-purifying filter that utilizes the shells.Read More

Cheap, waterless toilet that turns waste into clean water and power to be trialed in Africa

A cheap, easy to maintain, "green" toilet that uses no water and turns human waste into electricity and clean water will be trialed in 2016, possibly in Ghana. Dubbed the "Nano Membrane Toilet" by its creators from Cranfield University, UK, this new approach to managing waste could help some of the world's 2.3 billion people who have no access to safe, hygienic toilets.
