A dolphin that was sunburned while stranded out of water on mudflats for 24 hours in May appears to be recovering from its injuries.

Decompression computers worn by recreational and commercial divers provides accurate data, study shows

Millions of holidaying scuba divers are able to become citizen scientists and take vital measurements of ocean temperatures, which are being driven up by climate change.

More than 90% of the heat trapped by global warming goes into oceans, where it drives hurricanes and disrupts fish stocks. Satellites can measure surface temperature when there are no clouds, but getting data from below the surface is much harder and more expensive.

Delamere Forest, Cheshire Red and blue damsels drift around me like filaments on the breeze but I am here to see a rarer species: the white-faced darter

I skirt the edge of lower Doolittle Moss, in Delamere Forest, treading through soft peaty soil and batting away the pungent bracken that has grown almost as tall as me. Hard green fruit are starting to appear on the brambles, and bumblebees are making the most of the last blossoms.

Surrounded by forest on all sides, the moss is black acidic water devoid of fish. Not the least bit inviting, even as the temperature climbs. But it is a boggy beauty spot in its own right. Half submerged islands of vivid lime-green sphagnum moss break the surface. Stands of cotton grass and sedge shoot upwards, and above them the sunlight catches on flakes of silver and gold.

In a year of record global growth, solar PV broke records in Australia in 2015 too, with biggest ever year for big solar helping to balance fall in rooftop market.

There are several reasons that Australia lags behind other wealthy countries on energy efficiency.

South Australia's conservative opposition said to be source of dodgy numbers behind The Australian's erroneous front page story on wind energy in the state.

New analysis shows how gas generators cashed in on the recent big spikes in wholesale electricity prices in Australia. But they were not the only ones to benefit. The regulator is investigating to check that all is above board, but it's complicated.

There is a lot of noise about South Australia and not enough analysis. And there are some important lessons from the last few weeks of high prices.

Tesla Motors has revealed the Australian price for the entry-level version of its much-hyped Model X SUV – “the safest, quickest and most capable sport utility vehicle in history.”

TWO-WAY CONVERSATION: Not only do hunters in Mozambique recruit wild birds to help find honey, the birds actively recruit the hunters, reveals a new study of the remarkable relationship between humans and wild animals

With hydrogen tipped to become an important clean energy fuel, a new process may be the solution to powering electric vehicles and heating buildings

An Australian company is using “cheap as dirt” iron ore to convert methane in natural gas into hydrogen. Importantly, their process generates near-zero emissions, as the carbon content of the gas is captured in the form of high-quality graphite.

As a clean-burning fuel, hydrogen could play a key role in future energy markets, but production methods are still too energy-intensive and costly.
