By only using  a cardboard box, poster board and some tissue paper, you can create an inexpensive light box. Good jewelry and close-up photography requires good lighting. However, being able to light a piece properly to show the true color and beauty of it can be difficult. A light box is a great solution. It provides light diffusion and a uniform background against which to place your piece.

The Lens would cost more than an AUV! The camera and the lens weighed like a ton ( they say that the lens alone weighs like 13lbs)! Holding the cam and the lens for a shot is basically for show. With its combined weight, this is best operated with a sturdy tripod. Source

LONDON: Organic food has no nutritional or health benefits over ordinary food, according to a major study published Wednesday.

Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its perceived health benefits, creating a global organic market worth an estimated $48 billion in 2007.

A systematic review of 162 scientific papers published in the scientific literature over the last 50 years, however, found there was no significant difference.

“A small number of differences in nutrient content were found to exist between organically and conventionally produced foodstuffs, but these are unlikely to be of any public health relevance,” said Alan Dangour, one of the report’s authors.

“Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority.”

The results of research, which was commissioned by the British government’s Food Standards Agency, were published in the American Journal of Clinical Nutrition.

Sales of organic food have fallen in some markets, including Britain, as recession has led consumers to cut back on purchases.

The Soil Association said in April that growth in sales of organic products in Britain slowed to just 1.7 percent in 2008, well below the average annual growth rate of 26 percent over the last decade, following a plunge in demand at the end of the year.

The two-part study, consisting of a brain CT scan and a scoring system, showed Pycnogenol lowered symptoms of jetlag such as fatigue, headaches, insomnia and brain edema (swelling) in both healthy individuals and hypertensive patients. Passengers also experienced minimal lower leg edema, a common condition associated with long flights.

Jetlag is a temporary disorder that causes a variety of temporary mental and physical impairments as a result of air travel across time zones. It is caused due to the body’s inability to immediately adjust to the time in a different zone while traveling. As the body struggles to cope with the new schedule, temporary conditions such as insomnia, fatigue, irritability and an impaired ability to concentrate may set in.

“This study could not have come at a better time for the upcoming holiday travel season,” said Gianni Belcaro, a lead researcher of the study. While more research needs to be conducted on this topic, Pycnogenol is emerging as natural, yet safe option for long distance travelers.

The researchers attributes Pycnogenol’s combined activities for better circulation and antioxidant potency to such remarkable results.

The researchers stretch out large fibres to make thin threads

Clothes could one day take snaps of everything happening around whoever is wearing them.

US researchers have made smart fabric that can detect the wavelength and direction of light falling on it.

The research team has found a way to accurately place sensors in each fibre and co-ordinate the electrical signals they send when light falls on them.

The results were a step towards “ambient light imaging fabrics” said the researchers.

Led by Dr Yoel Fink from the Massachusetts Institute of Technology, the researchers have extended earlier work that placed sensors in relatively large polymer fibres.

Dr Fink and colleagues found a way to stretch the 25mm strands of polymer into much thinner fibres while maintaining the relative positions of the sensors.

This earlier work has led to the creation of very long and flexible light and temperature sensors that may find a role in smart fabrics for soldiers or those working in hostile environments.

In their latest work, described in a paper in Nano Letters, these thinner strands were woven into a 0.1m square section of fabric. The careful creation of the fibres and positioning of the light-sensitive elements meant that the team knew which signals were being sent by which sensors.

This enabled the team to reconstruct, albeit crudely, an image projected onto the small square of fabric. The researchers said their work was an “important step” towards finding ways to get many nanoscale devices working together. Source

Ron explains how being fitted with a 'bionic eye' has changed his life

He says he can now follow white lines on the road, and even sort socks, using the bionic eye, known as Argus II.

It uses a camera and video processor mounted on sunglasses to send captured images wirelessly to a tiny receiver on the outside of the eye.

In turn, the receiver passes on the data via a tiny cable to an array of electrodes which sit on the retina – the layer of specialised cells that normally respond to light found at the back of the eye.

When these electrodes are stimulated they send messages along the optic nerve to the brain, which is able to perceive patterns of light and dark spots corresponding to which electrodes have been stimulated.

The hope is that patients will learn to interpret the visual patterns produced into meaningful images.

The bionic eye has been developed by US company Second Sight. So far 18 patients across the world, including three at Moorfields, have been fitted with the device. Read more…..
