Rare Earth Metals - a Bottleneck in Supply?

Rare Earth Metals - a Bottleneck in Supply?

Posted Sat, 04 Jun 2011 07:47:01 GMT by Julian Jackson

Vital element in clean technology could have shortages, but new mines are on the horizon. China currently supplies 97% of the so-called Rare Earths - metal elements which are vital to green technologies like electric cars, fuel cells or wind turbines, not to mention iPhones, plasma screens, and myriads of other consumer goods.

Electricity can be generated by harnessing the wasted effort of industrial machines reducing emissions and saving money say a Finnish team. The team at Aalto University have used the technique on construction and mining machines, agricultural machines and material handling machines, capturing lost energy to use instead of fuel.

NASA researechers have mapped the earth's forests as a baseline for carbon research and monitoring efforts, and as a tool for managing global carbon dioxide. The map shows that the tropical forests that store the most carbon are in Latin America.

It was global cooling rather than global warming, but American climate scientists say new evidence points to the catastrophic effects of climate change on a Viking settlement on Greenland.

75 EVs to be road tested as part of low-carbon transportation network. The Dutch port city of Rotterdam is pushing forward on its plan to explore the possibilities of Electric Vehicles (EVs) for public transport and utilities. 75 EVs of different types are to operate on the roads in this bustling maritime city.

With car manufacturers continually improving fuel efficiency, attention is turning not just to the technology but also to the way we drive. As part of that growing awareness, US manufacturer Ford has been experimenting with vehicles which save fuel by helping motorists to avoid congestion and the waste of fuel which can be caused by idling engines.

An experiment by researchers from the University of Missouri proves that playing violent video games increases aggression. It takes only common sense and knowing a child who plays violent video games to know that such games increase aggression. So it isn't suprising that according to a recent study ''scientists have known for years that playing violent video games causes players to become more aggressive.''

An off-the-wall alternative energy source - bacterial batteries - is drawing closer thanks to new research published today, on the electricity-generating potential of 'rock-breathing' microbes. A paper out in Proceedings of the National Academy of Sciences describes in detail the mechanism by which these bizarre bacteria can pass electrical currents when attached to iron particles.

'Greenhouse' Effect Endangers Ocean Life

'Greenhouse' Effect Endangers Ocean Life

Scientists discover that the 'greenhouse' effect isn't constrained to the atmosphere. A team of geologists from Newcastle University in the UK have discovered evidence that 'greenhouse oceans' occurred in prehistoric times, resulting in areas of ocean with little or no life due to low levels of oxygen in the water.

Melting model for Greenland's accelerating ribbons of ice shows 'locked-in' sea level rise

Melting model for Greenland's accelerating ribbons of ice shows 'locked-in' sea level rise

A new study has projected future sea-level rises, just from Greenland's melting ice-sheets, at 3.5 inches over this century. The paper in the Proceedings of the National Academy of Science attempts to produce more complex computer models of recent dramatic ice-shelf losses that have kick-started accelerating Greenland glaciers - something the IPCC admits is poorly understood.

African farmers to benefit from genes resistant to cattle 'sleeping sickness'

African farmers to benefit from genes resistant to cattle 'sleeping sickness'

Posted Mon, 16 May 2011 19:00:00 GMT by Martin Leggett

An important research project that could ultimately see the defeat of the trypanosome parasite - the scourge of Africa's cattle herds - comes out today in Proceedings of the National Academy of Sciences. With millions of African farmers reliant on healthy cattle for food, as milk-producers and for the plowing of fields, the discovery of the specific genes responsible for resistance to the cattle-form of 'sleeping sickness' is being seen as a major breakthrough.

Dr Henry Ruhl of the National Oceanography Centre, Southampton and Professor Monty Priede of the University of Aberdeen, argued for independent monitoring of the deep-sea hydrocarbon industry as a means to gain a better understanding of its potential ecological activity and as a means of providing early warning of problems.

A ''hot Jupiter'' is a planet larger than the Jupiter of our own solar system which occupies an orbit close into its own star - hence ''hot Jupiter''. The conundrum was why should these giants be travelling in the wrong direction?
