Methane emissions from abandoned oil and gas wells underestimated
A recent study finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the US have been greatly underestimated – by as much as 150% in Canada, and by 20% in the US. Indeed, the research suggests that methane gas emissions from AOG wells are currently the 10th and 11th largest sources of anthropogenic methane emission in the US and Canada, respectively.
New eco-friendly way to make ammonia could be boon for agriculture, hydrogen economy
Ammonia has sustained humanity since the early 20th century, but its production leaves a huge carbon footprint. Now researchers have found a way to make it 100 per cent renewable.
Land deals meant to improve food security may have hurt
Large-scale land acquisitions by foreign investors, intended to improve global food security, had little to no benefit, increasing crop production in some areas while simultaneously threatening local food security in others, according to researchers who studied their effects.
Constructing termite turrets without a blueprint
Following a series of studies on termite mound physiology and morphogenesis over the past decade, researchers have now developed a mathematical model to help explain how termites construct their intricate mounds.

Gene-editing ‘scissor’ tool may also be a ‘dimmer switch’
In a series of experiments with laboratory-cultured bacteria, scientists have found evidence that there is a second role for the widely used gene-cutting system CRISPR-Cas9 — as a genetic dimmer switch for CRISPR-Cas9 genes.
Research finds tiny bubbles tell tales of big volcanic eruptions
(Rice University) Microscopic bubbles can tell stories about Earth’s biggest volcanic eruptions and geoscientists from Rice University and the University of Texas at Austin have discovered some of those stories are written in nanoparticles.
