There have been multiple reports of high-tech, insect like drones at recent political rallies that some people suspect are micro-air surveillance vehicles that have been under development by the U.S. intelligence community.
Scientists said yesterday that they had achieved a long-sought goal of slowing waves of light to a relatively leisurely pace and using those harnessed pulses to store an image. Physicists said the new approach to taming light could hasten the arrival of a futuristic era in which computers and other devices will process information on optical beams instead of with electricity, which for all its spark is still cumbersome compared with light.
Amid growing evidence that some of the tiniest materials ever engineered pose potentially big environmental, health and safety risks, momentum is building in Congress, environmental circles and in the industry itself to beef up federal oversight of the new materials, which are already showing up in dozens of consumer products.
Scientists said yesterday that they have determined the precise order of the 3 billion bits of genetic code that carry the instructions for making a chimpanzee, humankind's closest cousin.
South Korean researchers have announced the successful creation of the world's first dog. The feat suggests that a market in cloned dogs, through which people grieving the loss of their favorite pets could order genetic duplicates, may not be as futuristic as some had thought. And by leapfrogging a seven-year-old, multimillion dollar U.S. effort, the success has clinched South Korea's quickly growing reputation as a premier center for cloning and stem cell research.
About a third of an ounce of botulism toxin poured by bioterrorists into a milk truck en route from a dairy farm to a processing plant could cause hundreds of thousands of deaths and billions of dollars in economic losses, according to a scientific analysis that was published yesterday despite efforts by federal officials to keep the details secret.
After seven years of debate, the U.S. Patent and Trademark Office has denied a scientist a patent for a genetic chimera that is part human and part animal. The ruling was a victory for the scientist who was trying to create legal precedent against the creation of human-animal chimeras but it also raises serious questions about using the Patent office to govern emerging genetic technologies.
Researchers are debating the ethics of creating chimeras -- creatures that are part animal and part human.
The invisibly small particles and fibers that scientists are producing in the hot new field of nanotechnology pose health and environmental risks great enough to justify banning, for now, certain cosmetics now found on the U.S. market and also halting the deliberate release of nanomaterials into the environment, according to an independent report commissioned by the British government.
The first study to look at the health effects of microscopic, manufactured "nanoparticles" on aquatic animals has found troubling evidence that the molecules -- which scientists are starting to make for research and industry -- can trigger organ damage and other toxic effects.
