Changes in Earth’s orbit enabled the emergence of complex life

‘Snowball Earth’ is the most extreme climate event in Earth’s history, when it was completely engulfed in ice. The theory of its existence has faced two challenges – how life survived and variations in rock formations from the time implying changes to the climate cycle. New study shows that changes to Earth’s orbit caused the

Methane in plumes of Saturn’s moon Enceladus: Possible signs of life?

A study concludes that known geochemical processes can’t explain the levels of methane measured by the Cassini spacecraft on Saturn’s icy moon. While the paper by no means suggests that life exists on Enceladus, the results would be consistent with microbial activity similar to that known to occur at hydrothermal vents in Earth’s oceans.  Title:

Floods may be nearly as important as droughts for future carbon accounting

In a 34-year global analysis, researchers found that photosynthesis — an important process for removing carbon dioxide from the atmosphere and storing it in soil — was controlled by extreme wet events nearly as often as droughts in certain locations.

Storing carbon inn rocks underground: Old oil fields may be less prone to induced earthquakes

Subsurface carbon sequestration — storing carbon in rocks deep underground — offers a partial solution for removing carbon from the atmosphere. Used alongside emissions reductions, geologic carbon sequestration could help mitigate anthropogenic climate change. But like other underground operations, it comes with risks — including earthquakes. Title: Storing carbon inn rocks underground: Old oil fields

Data from boreholes in plate boundaries could explain slow earthquakes

Slow earthquakes are long-period earthquakes that are not so dangerous alone, but are able to trigger more destructive earthquakes. Their origins lie in tectonic plate boundaries where one plate subsides below another. Though the causal mechanism is already known, there has been a lack of data to accurately model the life cycle of slow earthquakes.

Paleonursery offers rare, detailed glimpse at life 518 million years ago

All life on Earth 500 million years ago lived in the oceans, but scientists know little about how these animals and algae developed. A newly discovered fossil deposit near Kunming, China, may hold the keys to understanding how these organisms laid the foundations for life on land and at sea today, according to an international

Earth-like biospheres on other planets may be rare

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth. Title: Earth-like biospheres on other planets may

‘Fool’s gold’ not so foolish after all

New research has found tiny amounts of gold can be trapped inside pyrite, commonly known as ‘fool’s gold,’ which would make it much more valuable than its name suggests.

Environmental impact of hydrofracking vs. conventional gas/oil drilling: Research shows the differences may be minimal

Researchers have developed a new machine learning technique to holistically assess water quality data in order to detect groundwater samples likely impacted by recent methane leakage during oil and gas production. Using that model, the team concluded that unconventional drilling methods like hydraulic fracturing do not necessarily incur more environmental problems than conventional oil and
