“World’s oldest fossils found in discovery with ‘staggering’ implications for the search for extra-terrestrial life”
The oldest known fossils – dating back 3.7 billion years to a time when the Earth was still being bombarded by asteroids – have been found in Greenland, scientists announced in a discovery that could have “staggering” implications.
Commenting on the discovery, a Nasa expert on the early Earth said if the fossils were evidence of living creatures then the discovery showed “life is not a fussy, reluctant and unlikely thing” – increasing the chances that it will have developed on Mars and elsewhere in the Universe.
The transition to renewables, wind and solar power in particular, has typically run ahead of expectations this decade and fresh data from the United States illustrates this phenomenon nicely. In the first half of this year, combined wind and solar provided 140.97 TWh of the 1959.20 TWh generated in the country.
Grid-scale electricity storage will move closer to commercial reality on Friday when the U.K.’s grid operator offers contracts to companies to help balance the network, a key measure needed to help balance increasing supply from renewables.
A game changing moment for the UK.
The Environmental Audit Committee says the tiny balls of plastic used in shower gels and facial scrubs can even be found in Arctic sea-ice and on the ocean floor.
The MPs say synthetic fibres from worn car tyres and fleece jackets may also be harming wildlife.
So how did an international environmental champion fail to meet the promises of a sustainable Rio in time for the city’s biggest international event in decades?
U.S. Department of Agriculture researchers have discovered that a milk protein called casein can be used to develop an edible, biodegradable packaging film. The casein-based film is up to 500 times better than plastic at keeping oxygen away from food because proteins form a tighter network when they polymerize, the researchers found. It’s also more effective than current edible packaging materials made from starch and protects food products that are sensitive to light.
It’s time to have a conversation about flatulent cows.
The hamburgers and cheese that come from U.S. cattle may be favorite fare at many summer cookouts, but the methane the same cows produce is significantly less appetizing.
That’s especially the case for sustainable investors looking for a low-emission place to park their cash. “Enteric fermentation,” or livestock’s digestive process, accounts for 22 percent of all U.S. methane emissions, and the manure they produce makes up 8 percent more, according to the U.S. Environmental Protection Agency.
And although agriculture is a growing industry as the world looks to feed its swelling population, some investors are reluctant to support a sector with such a hefty methane footprint.
