AirCSI is a prototype drone system that scans crime scenes from above, identify possible pieces of evidence, and then collect more detailed images and data of such items of interest. Leading the development of the system is Pompílio Araújo, a researcher at the Intelligent Vision Research Lab at Federal University of Bahia who often assists the Federal Police of Brazil in crime scene investigation. From IEEE Spectrum:
"...AirCSI provides a sketch with the localization of the evidences, as well as a detailed crime scene imagery,” says Araújo. His team used simulation software to test this newer version of AirCSI, and found that using multiple angles to detect evidence is up to 18 percent more effective than using only one angle...
While the researchers have yet to test the new, multi-angle approach beyond simulations, they expect to try it out in a real environment by the end of this year or early next year...
He also plans on developing a way to completely reconstruct crime scenes using the drone footage, creating a virtual environment that investigators can explore indefinitely—or at least until the crime is solved.

When eight- and nine-year-old students at Hyde England's Flowery Field Elementary School walked into class last week, they were confronted with a crime scene. Behind the police tape was chalk outline of an elfin figure and a desk smeared with blood. Their assignment? Solve the mystery of the murdered elf. Apparently it was a writing exercise. And surprise! Some parents were pissed.
"My daughter came home and she was absolutely traumatized," one parent said. "I'm not the only parent who felt like that. A lot of the kids in Year 4 were unsettled by it."
Apparently, that did not discourage head teacher Ian Fell who encouraged the students to continue their detective work.
"I have been a teacher for 30 years and this is, in my judgement, an appropriate, engaging and exciting thing that children aged eight and nine have done," Fell said. "They have been so up for it."

The prisoner strapped under a descending pendulum blade. A raven who refuses to leave the narrator’s chamber. A beating heart buried under the floorboards. Poe’s macabre and innovative stories of gothic horror have left a timeless mark on literature. But just what is it that makes Edgar Allan Poe one of the greatest American authors? Scott Peeples investigates.
Steven Brust is a literary treasure
and his longrunning Vlad Taltos series
, now nearing its final volume, is a good example of where his strengths lie: hardboiled plotting, snappy dialog, weirdly realistic and plausible depictions of magic, and a sensitive eye for power relationships and their depiction, all of which are on display in his latest, outstanding novel, Good Guys
, about the minimum-wage sorcerers who investigate magical crimes on behalf of a secret society.
