From soil to clouds: African farmers benefit from improved rainstorm predictions

From soil to clouds: African farmers benefit from improved rainstorm predictions

Posted Sun, 12 Jun 2011 17:00:00 GMT by Martin Leggett

Thunderstorm predictions during the Sahel monsoon season, in Africa, are likely to be improved by work published in Nature Geoscience today. By using incredibly detailed satellite images, scientists have discovered that soil moisture levels can be a big factor in some of the crop-nourishing storms breaking out at that time of year.

With high oil prices are sailing ships about to make a comeback? In order to lower running costs, cargo ships are now often reducing speed to 12-15 knots, but this makes them slower than the sail-powered clipper ships of a century or more ago.

Oxygen-poor 'dead zones' ebb and flow across the oceans

Oxygen-poor 'dead zones' ebb and flow across the oceans

Posted Thu, 09 Jun 2011 18:00:00 GMT by Martin Leggett

Worries about the growth of oxygen-depleted dead zones may be eased by a new study, which models the 50-year evolution of low oxygen tongues and plumes across the oceans. The paper in Science shows that bacteria have a big influence on the ebb and flow of oxygen through the seas – but that a long term decline in oxygen, due to global warming, is still likely.

Call to save our soils, to save ourselves

Call to save our soils, to save ourselves

In today's Nature, a scientist is pointing to the role of 'Critical Zone Observatories' in understanding soils and fast-tracking solutions to preserve them - even as greater demands are placed on them. With the roots of civilization holding on tenuously to the denuded resources of the soil, action is needed fast, says Prof. Banwart.

Social factors influence local farmers' willingness to accept sustainable technologies, a Stanford study shows. Local farmers may only accept sustainable and more cost-efficient methods if trusted resources promote the new methods.

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.

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.''
