China’s functional food honey-trap
Two brief reports in the most recent edition of Food Manufacture magazine reflect the fascination that the western industrialised world has in the opportunities and dangers of doing business in China. On the one hand, a delegation of food manufacturers and academics brought back information on some 8000 ingredients used in traditional Chinese medicine from…
World Water Day
March 22nd is World Water Day, which this year is themed: ‘Coping with Water Scarcity’. This year’s theme highlights the increased significance of water scarcity across the globe – From Africa and increased desertification, Australia and the increase in the number of droughts in past years to the UK and the water shortage that hits…
Cow + Grass = House
Cows plus grass equals dung; 7-9 million tonnes of it each year in the USA alone! What if cows plus grass made flooring?, or shelving? or a table? Michigan State University researchers, working with the US Department of Agriculture, reckon that the "digester solids" leftovers from anaerobic digestion of cattle manure can be processed into…
Celebrating Linnaeus
2007 marks the 300th anniversary of the birth of Linnaeus, father of binomial nomenclature. Nature has marked the occasion by publishing a special issue crammed full of Linnaean-inspired thought. Although trained in medicine and a keen zoologist, Linnaeus is perhaps best known as an excellent botanist – his field trips were said to be so…
Atkins – the right strategy for the wrong reasons?
‘Atkins is best diet around, says Stanford University.’ Apparently, though I am sure that many scientists looking at the study in any sort of detail might wonder how Stanford’s nutritionists have managed to reach this conclusion. A few years ago, when the Atkins craze was at its height, a number of studies commissioned to test…
The Great Global Warming Swindle – don’t forget the science
If you saw this programme on Channel 4 last Thursday (8 March) you will probably either be shocked and appalled that Channel 4 could possibly dare to air such a programme, or you will be relieved that somebody finally took a look at the science behind the theory and presented an alternative view. The programme…
My love is like a blue, blue rose
I wonder if Robert Burns would have felt as inspired about blue roses as he was about the romantic red. Personally speaking, I prefer my geraniums red and delphiniums blue although I find the desire for horticultural oddities quite fascinating. For many centuries a true blue flower has been the Holy Grail of plant breeders…
Polarized thought
After spotting a Grist Magazine article about a climate change-induced human rights claim, and then a story last week from Scientific American about International Polar Year, I thought it was time to mention the effect of global warming on humans. The human climate change link is not often considered, but Inuit people launched a human…
A Role for Rice in Causing and Tackling Climate Change?
Rice provides the staple food for around 2 billion people, and demand is forecast to grow at 1% a year, with no increase in land available. Some recent studies have indicated that rice production is contributing to climate change through emissions of greenhouse gases (GHG). An analysis by Reiner Wassmann, Klaus Butterbach-Bahl and Achim Dobermann…
Grassland invaders had inside help
One of the key factors in an alien species becoming invasive in an area is that it survives better in the new habitat than the native species, right? Well it’s not always quite that simple. Researchers from Oregon State University have documented a case where stronger native grasses were out-competed and replaced by inferior challengers.…
