Sure Fire: New Smart Bullets Designed With Mini 'Wings' For Guided Precision

Until now, good marksmanship had everything to do with the person firing the gun. That could soon change. Researchers in New Mexico have developed a computerized super bullet that can guide itself to the target.

For now, marksmanship still requires good aim (mrbill)

Researchers in the United States have come up with a next-generation bullet that uses an optic sensor and tiny wings to zero in on its target.

At the tip of the 10-centimeter long bullet is a sensor that heads straight for wherever a laser is pointing. The sensor sends the data it picks up to a processor inside the bullet. The mini-computer figures out the ideal trajectory and corrects it if necessary. The data is transmitted to wings that operate similarly to the way feathers on a dart work. The wings can be steered, however, and thus guide the bullet to its target.

The mini wings are protected by a plastic covering that falls away after the bullet leaves the weapon. The wings also have another function. Normal bullets stabilize their flight by quick self rotation. However, that also means they can't be driven to a target with precision. But because of the wings there is no rotation in the new bullets, and they can be driven.

Engineers Red Jones and Brian Kast of the Sandia National Labs in the U.S. state of New Mexico developed the bullets and have successfully conducted initial tests. A night test showed clearly how the bullet with the light-emitting diode changed course. However, exactly how precisely it hit target could only be recreated on computer models. According to the models, bullets shot from a distance of 1 kilometer can occasionally be up to 20 centimeters off course. Shot from the same distance, a normal bullet could be off by as much as 9 meters.

The experimental bullets can reach a speed of over 700 meters per second (Mach 2.1). Potential buyers of the technology include hunters, but mainly the military and the police. "We've developed very promising technology that can be made quickly and for little money," says Jones. The two engineers and hobby-hunters are currently looking for a company willing to invest in the final testing phase and development of a product brand.

Squash That Vegan Cannelloni! The Politics Of Going Meat-Free Is Hotter Than Ever

A German politician got a taste for the backlash that can come from getting close to the vegetarian movement, especially as environmental factors make the choice even more loaded than at its birth in the animal rights movement.

PARISEating meat-free can sometimes come with consequences. Just ask German center-right politician Silke Gorissen, who has been in full damage-control mode since participating at a seemingly ordinary vegan-vegetarian awareness event last month at the University of Bonn.

Gorissen, who serves as the Minister of Agriculture for North Rhine-Westphalia state, made the usual rounds at the veggie event, offering typical politician praise for the local fruit and vegetable products. And then she tasted the vegan cannelloni…

Indeed, it was the Minister’s public praise for the meatless take on the classic Italian stuffed pasta recipe (traditionally served with ground beef or pork) that set off an uproar — a reminder that the debate over vegetarian diets can still be explosive.

German daily Die Welt reported that rumors followed the University event that the government was about to declare a meat-free month for the state — rather than just the student dining hall. In the heartland of German pig farming, it makes sense that the local farmers oppose anti-meat initiatives that could affect their livelihoods.

Still, there is something about vegetarianism that goes beyond simple economics.
