In response to climate change, will a postage-sized-domain move uphill - and ultimately out of room?

Climate change is on your porch and in your backyard and living room - anywhere you bedeck with flowering plants, but global warming affects favourite flowers of garden and vase. This is true of plants around the world, including the proteas and the pelargoniums native to South Africa, writes Cheryl Dybas, of the National Science Foundation.   Read More...

... And understanding the past can help us understand the present, and the future, even better.

High tech X-ray scanning equipment has opened up a whole new world to scientists studying delicate specimens such as fossils, skeletons and ancient manuscripts. Scientists are now able to see very precisely how evolution has led from animals that lived perhaps millions of years ago, to their modern decendants. Who knows... that could have relevance in the environmental area.   Read More...

Lions have lost three-quarters of their original natural habitat in Africa.

The report, courtesy of Panthera and World Science staff, reaches a sombre conclusion: Western Africa, in particular, must be given money to protect the lions' habitat as people have taken it over for their own purposes, according to a new study. Billed as the fullest assessment to date on the state of African savannah, or grassland, habitat, the report says the habitat loss has devastated lion populations.

- Southern Africa Oil & Gas Summit, Cape Town

Speaking at the Southern Africa Oil & Gas Summit in Cape Town, TKAG Chair, Jonathan Deal cautioned delegates not to rush into investment decisions around shale gas mining in South Africa. In an address that included what he described as a sample of the hurdles facing the proponents of shale gas mining in SA, Deal said that in the view of TKAG, the technology was wholly inappropriate for South African conditions and that the applicants and the government would be challenged in the courts.   Read More...

Bee die-offs are a concern for the agricultural sector.

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. Researchers believe inappropriate data might have been used in earlier studies.   Read More...

Those fossils were brainier than we might have thought.

A remarkably well preserved fossil of an extinct, worm-like animal reveals that anatomically complex brains evolved earlier than previously thought, researchers say in a new study. Found in rock formed from mud deposits during the so-called Cambrian period 520 million years ago, scientists said, the roughly 75mm long fossil represents a primitive arthropod.   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...
