Health officials in the USA are currently investigating how melamine, a chemical used to make industrial glues, fire retardants and fertilisers, got into the USA’s food chain.
Investigators believe the chemical was added to rice-protein and wheat gluten supplements produced in China. Because purchasers of such imported products routinely measure nitrogen content to estimate the amount of protein in foods, it is believed the Chinese suppliers may have added melamine to make their products appear to contain more protein.
The adulteration was discovered after more than a dozen dogs and cats died after eating melamine contaminated pet food; scraps of this pet food were also fed to pigs and chickens destined for human consumption.
The Editorial says: “Although US health officials have determined that eating meat from these animals poses a very low risk to human health, the incident highlights how difficult it has become to guarantee food safety when the food supply depends on a vast worldwide network of producers, suppliers and distributors.”

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
