Nano-motors For Microbots 77

Smivs writes "The BBC are reporting on the development of tiny motors the size of a grain of salt which could power surgical Microbots. Some surgical procedures are hindered by the size or inflexibility of current instruments. For example, the labyrinthine network of blood vessels in the brain prevents the use of catheters threaded through larger blood vessels. Researchers have long envisioned that trends of miniaturisation would lead to tiny robots that could get around easily in the body. The problem until now has been powering them. Conventional electric motors do not perform as well as they are scaled down in size. As they approach millimetre dimensions, they barely have the power to overcome the resistance in their bearings. Now, research reported in the Journal of Micromechanics and Microengineering has demonstrated a motor about 1/4mm wide, about the width of two human hairs."

Researcher Finds No Link Between Violent Games and School Shootings 116

GamePolitics writes "A researcher at Texas A&M International University has found no link between playing violent video games and school shootings. Prof. Christopher Ferguson cites 'moral panic' and criticizes politicians, the news media and some social scientists for playing up what he believes is a false connection between video games and school shooting incidents. Quoting: 'Actual causes of violent crime, such as family environment, genetics, poverty, and inequality, are oftentimes difficult, controversial, and intractable problems. By contrast, video games present something of a "straw man" by which politicians can create an appearance of taking action against crime.'"
