Amazonian challenges: The loss of indigenous culture and identity

...ruling sets a negative precedent for the indigenous peoples of Guyana, who have been seeking to have their lands recognised and respected for decades. It also exposes the lack of adequate protections for indigenous lands in Guyana, a situation which will only be exacerbated as pressures from mining, logging, and carbon projects grow.” Next: How can the Amazon survive?...

Can landfills be used to improve biodiversity?

...carbon capture and directly by having access to some of these spaces for our own recreation and wellbeing. Understanding what shapes successful outcomes may also play a role in our future decision making. What can you do to help? A few minor changes could help to make a difference in the future of landfills and how we create spaces for nature. Support local organisations...

Fermanagh: The backdrop to the G8 summit

...carbonate rock. The water tends to drain into natural fissures and pools which deepen and widen as the rock is dissolved. The fissures (grykes) follow the grain of the rock and can be metres deep, though narrow. The pavement between the grykes (clints) may be pitted with small solution pools. Further south, the Burren is a magnificent limestone pavement while...

...carbon emissions, you'd be forgiven for thinking that China are the worst offenders. But there’s a trap here and that's the difference between emission per country and emission per person. Professor Hans Rosling explains (look at the video above for reference): "On this axis I show carbon dioxide emission per person, from a few tonnes per year to 10 and 20 tonnes per...

What can parasites on Arctic shrews tell us about climate change?

...carbon dioxide levels in the atmosphere are higher than they have ever been in the experience of these species, and the accompanying climate change is much more rapid,” says Hope. “That translates to conditions that no one has really experienced before, and we’re not sure exactly how animals and ecosystems are going to respond.” Hope’s work demonstrates that...

Apollo 11’s ‘one small step’ sparked a new rush to reach the Moon

...carbon, nitrogen, oxygen – in Moon rocks. Our findings suggest the presence of a water reservoir in the Moon which is similar to certain parts inside the Earth’s structure. Furthermore, the distinctive chemical composition of the water in the lunar samples points towards water in the Moon having a common origin with that of the Earth and asteroids. As we look forward...

Electrical Discharge Machining (EDM) and Grinding (EDG)

...carbon pick-up may occur in steel workpieces, leading to a hard martensitic layer. Design: Used extensively for tool and die work, and particularly suitable for irregular slots and cavities and small holes with high aspect ratios. Leaves no burrs. Holes down to 0.05 mm can be formed, but an allowance has to be made of 0.005–0.50 mm side-1 for “overcut”. Holes are...
