Sudden losses of honeybee colonies in the US and Europe cause alarm.

Contrary to some previous studies, crop pesticides are unlikely to cause devastating declines in honeybee populations, the authors of new research say in this article courtesy of the University of Exeter and World Science staff.   Read More...

Microorganisms that crashed to Earth embedded in the fragments of distant planets might have been the sprouts of life on this one, according to new research from Princeton University, the University of Arizona and the Centro de Astrobiología (CAB) in Spain, writes Princeton University's Morgan Kelly, in the Office of Communications.   Read More...

Have you got rubble trouble? Well, here's a new way to get rid of it.

Every year several millions of tons of building rubble are produced. An efficient way of recycling concrete – the building material of the 20th and 21st century – does not yet exist. Researchers are working on new recycling methods, and with the aid of lightning bolts, they can break down the mixture of cement and aggregate into its components.   Read More...

Answers may be in new NSF Water Sustainability and Climate research.

How will climate change affect the connections between water sustainability and hydrologic processes? To better understand how planet Earth's water cycle works, the National Science Foundation (NSF) and the United States Department of Agriculture's National Institute of Food and Agriculture (NIFA) awarded grants totalling almost $27 million through the Water Sustainability and Climate program.   Read More...

Five-year study shows that plants may quickly lose important traits through evolution soon after insects are removed from environment.

At first blush, many people would probably love to get rid of insects, such as irritating mosquitoes, ants and roaches. However, a new study indicates that getting rid of insects could trigger some unwelcome ecological consequences, such as the rapid loss of desired traits in plants, including their good taste and high yields.   Read More...

“Imagine living in a home that treads lightly on the environment…’’

“Imagine living in a home that treads lightly on the environment…’’, generates its own electricity, heats and cools itself and consumes very little electricity while thinking for itself…. well that’s the home of today and that’s the home that you can invest in…!” Alastair Armstrong, Electrical Engineer. Virtually everything we interact with in the home involves energy (think of it as money) at one level or another, writes Roger Metcalfe.   Read More...

What better for environmentally friendly energy than more efficient solar-cell production (and cheaper!)

The competition in the photovoltaics market is fierce. When it comes to price, Asian manufacturers are frequently ahead of the competition by a nose. Now, Fraunhofer researchers are designing new coating processes and thin layer systems that, if used, could help to reduce the price of solar cells significantly – and give the competitive edge back to German manufacturers, too.   Read More...

Now the job is to save it from extinction.

Scientists have identified a new species of African monkey, locally known as the lesula. The findings are described in the 12 September issue of the research journal PLoS One. This article courtesy of PLoS One and World Science staff. It is only the second new species of African monkey discovered in the last 28 years, biologists said.   Read More...

Yes, it IS possible to leave our children a better world.

Let me first explain why we need to bother. The credit crunch has shaken our global economy, but it will recover. ‘The Protein Crunch’ is far more serious and, if we open our eyes, it is unfolding right in front of us, writes Jason Drew* in this article reprinted courtesy of the Global Carbon Exchange - http://www.globalcarbonexchange.com.   Read More...

The very word sounds scary, but “fracking” holds tremendous promise for Algeria, Libya, Morocco and SA.

All of these countries possess large reserves of natural gas in deep shale rock layers. Environmentalists warn that it will poison the water and ruin the landscape. Some even call it “worse than coal”. Do they exaggerate or are the environmental risks small and the economic benefits too great to sacrifice? Ivo Vegter examines the research and cracks apart the opposition’s claims.   Read More...

Answer may be 'adaptive zones' that limit species number, life scientists report.

Scientists have often posited that because some animal and plant lineages are much older than others, they have had more time to produce new species (the dearth of crocodiles notwithstanding). This idea – that time is an important predictor of species number – underlies many theoretical models used by biologists. However, it fails to explain species numbers across all multi-cellular life on the planet, a team of life scientists reports 28 August in the online journal PLoS Biology, a publication of the Public Library of Science.   Read More...

Landscaping with indigenous (native) vegetation helps local bird species.

Gardens with plants that mimic native vegetation offer birds ‘mini-refuges’ and help to offset losses of biodiversity in cities, according to results of a study published today in the journal PLOS ONE. ‘Native’ gardens support birds better than those with traditional grass lawns and non-native plantings do.   Read More...

The good news, the bad news – and the future.

Many entities contact GCX with an opportunity they believe may be a carbon emissions reduction project that could generate and sell carbon credits. However the carbon project development process is an extremely costly, highly complex, bureaucratic and rigorous procedure fraught with frustration which is then compounded by the volatility and uncertainty of the carbon markets.   Read More...

Dissolution or creation of huge gypsum deposits changed sulphate content of the oceans.

Scientists have discovered a potential cause of Earth's ‘icehouse climate’ cooling trend of the past 45 million years - and it has everything to do with the chemistry of the world's oceans.   Read More...

Natural reserves in some cases might not be doing the job expected of them.

Many of the protected areas in tropical nations are struggling to sustain their biodiversity, according to a study by more than 200 scientists from around the world. The study, which will appear Thursday in the journal Nature, found that deforestation is advancing rapidly in these nations and most reserves are losing some or all of their surrounding forest, writes Alison Hewitt.    Read More...

SA is prone to droughts. This research could well have applications here.

UCLA life scientists, working with colleagues in China, have discovered a new method to assess plants’ drought tolerance quickly. The method works for many diverse species growing around the world. The research, published in the journal Methods in Ecology and Evolution, may revolutionise the ability to survey plant species for their ability to withstand drought, said senior author Lawren Sack, a UCLA professor of ecology and evolutionary biology.  This article has been written by Stuart Wolpert, UCLA.
