The Wing-Friends and Other Books

In Blogger's slideshows images are greatly reduced, so lose much of their impact. And captions added to them in Picasa Albums vanish, so the images shown above are: the Milky Way, the Orion Nebula, Earth, Earth with New Zealand circled, New Zealand, Auckland & the Hauraki Gulf, Waiheke Island, some native NZ forest, a Fantail and chicks, various doves, etc.

(If you want to see the first ten images in their original size, they are in a posting made on the 24th of November 2011.)

My book The Wing-Friends is an imaginative tale of a small brave boy, a magical adventure, a magnificent Pegasus and the wonderful Kingdom of the Pegasi. It has been given very good reviews, and virtually every reader on Goodreads has so far awarded it five stars. It is available here. Some of my other writings are available as e-books, such as The Lower Deck, which is an over-the-top take on Waiheke happenings--sort of.

NET GLEANINGS 044

Simple world-changing technology gives any plant the ability to fix nitrogen from the air and thus be self-fertilising:
'Speaking about the technology, which is known as 'N-Fix', Professor Cocking said: "Helping plants to naturally obtain the nitrogen they need is a key aspect of World Food Security. The world needs to unhook itself from its ever increasing reliance on synthetic nitrogen fertilisers produced from fossil fuels with its high economic costs, its pollution of the environment and its high energy costs." N-Fix is neither genetic modification nor bio-engineering. It is a naturally occurring nitrogen fixing bacteria which takes up and uses nitrogen from the air. Applied to the cells of plants (intra-cellular) via the seed, it provides every cell in the plant with the ability to fix nitrogen. Plant seeds are coated with these bacteria in order to create a symbiotic, mutually beneficial relationship and naturally produce nitrogen.'

Common agricultural chemicals impair honey-bees' health:
'Commercial honey bees used to pollinate crops are exposed to a wide variety of agricultural chemicals, including common fungicides which impair the bees' ability to fight off a potentially lethal parasite, according to a new study by researchers at the University of Maryland and the U.S. Department of Agriculture.'

Simple tool to 'tinker' with any human gene:
'Duke researchers have devised a way to target any gene in the human genome and tinker with it. The new tool, which builds on an RNA-guided enzyme they borrowed from bacteria, is being made freely available to researchers who may now apply it to the next round of genome discovery.... it works, and it works on genes that matter from a clinical perspective. In principle, the RNA-guided tool could be used to modify or influence any gene anywhere in the genome.'

'Printed' rocket parts as good as machined ones, and far cheaper:
'Traditional subscale rocket injectors for early SLS acoustic tests took six months to fabricate, had four parts, five welds and detailed machining and cost more than $10,000 each. Marshall materials engineers built the same injector in one piece by sintering Inconel steel powder with a state-of-the-art 3-D printer. After minimal machining and inspection with computer scanning, it took just three weeks for the part to reach the test stand and cost less than $5,000 to manufacture.'
