Taking the pulse of carbon emissions could measure climate impact of development
A new way to 'take the pulse' of carbon emissions could help track how the industrial development of peatlands contributes to climate change, as well as measure their recovery once development ends. In a new paper published in the journal Scientific Reports, a team of researchers led by the University of Glasgow discuss how they have used carbon-14 dating to determine for the first time the age of carbon dioxide being released from peatland sites.

How our biological clocks are locked in sync
Scientists from EPFL's Institute of Bioengineering have discovered that our circadian clock and our cell-cycle are in fact, synchronized. Nothing in biology is static; everything is fluid, dynamic and ever-moving. Often, this movement occurs in repeating patterns - regular, measurable cycles that tick just like "clocks".

Coca and conflict: the factors fuelling Colombian deforestation
Coca and conflict: the factors fuelling Colombian deforestation
Deforestation in Colombia has been linked to armed conflict and forests' proximity to coca crops, the plant from which cocaine is derived. A University of Queensland-led study found that conflict between illegal groups and the governmental military forces, proximity to coca plantations, mining concessions, oil wells and roads were all associated with increased deforestation.

First cells on ancient Earth may have emerged because building blocks of proteins stabilized membranes
First cells on ancient Earth may have emerged because building blocks of proteins stabilized membranes
Life on Earth arose about 4 billion years ago when the first cells formed within a primordial soup of complex, carbon-rich chemical compounds. These cells faced a chemical conundrum. They needed particular ions from the soup in order to perform basic functions. But those charged ions would have disrupted the simple membranes that encapsulated the cells.
