Forensic science and fingerprints

...carbon, C; chlorine, Cl; copper, Cu; iron, Fe; hydrogen, H; nitrogen, N; sodium, Na; oxygen, O; and sulfur, S. Molecules: molecular and structural formulas Molecules are electrically neutral collections of atoms bound together in specific proportions. Each molecule has a particular geometric arrangement of atoms. One way of describing molecules is to use their molecular...

Climate change’s costs are still escalating

...and other carbon sinks. The delegates at the conference will be discussing ways to better prepare for and create warning systems to improve disaster response. They will also be recommended to take steps to reduce casualties by enhancing drainage to reduce flood risks and by strengthening healthcare, especially in poor areas. By Paul Brown - The Climate News Network...

As Cassini reaches the end, we should prepare the next mission

...carbon dioxide – plus traces of other organic molecules – in the plume. This lead to to much speculation about the possibility of life in the ocean. Like Titan, Enceladus is now recognised as one of the solar system’s most likely locations for extraterrestrial life. A recent report of hydrogen in Enceladus’ plume has given that recognition even greater prominence....

The Legacy of Nuclear Power, Part 2

...carbon, all this sort of stuff. And in terms of the nuclear debate in my view, nuclear is probably as an industry ultimately doomed. But I think the point I would want to emphasise above all is that we should not be creating more waste beyond what we know we are already gonna have because we won't know what the inventory is. We won't know how long it is gonna go on for....

Microbes – friend or foe?

...carbon dioxide and water (together with energy needed for the microbes to stay alive). Aerobic respiration is the most efficient way of breaking down organic matter although some compounds in the effluent are not broken down completely. The tanks often contain porous solid materials, on which biofilms can develop, increasing the numbers of microbes and so the efficiency...

The Peace Dividend: why Good Friday Agreement matters to us and Earth

...carbon emissions (the driver of the greenhouse effect, and therefore global heating), but about all the ways in which our economy interacts with the earth, it extracts and transforms energy and matter to produce the things we need (and, more unsustainably, want). The earth can only sustainably reproduce about 7 tonnes of material per person per year – the Northern...

Supporting sustainable and responsible space exploration

...carbon fibre, adhesives, lubricants, greases and more – each with its own function and its own history of cleanliness. A huge amount of industry’s investment in planetary protection goes towards identifying the ways contamination of spacecraft happens and how it can be contained. For example, a common approach is to isolate critical areas of the spacecraft where...

The ice-covered ocean worlds of the outer Solar System

...carbon dioxide into sugars and other biologically useful molecules, a role normally fulfilled by photosynthesis in plants on the Earth’s surface. Studies using data from the Cassini mission have shown that some of the microorganisms that live in hydrothermal vents deep in Earth’s oceans could survive in Enceladus’s ocean, using hydrogen as their main source of...
