New tech could tell CSIs when fingerprints were made

A suspect says it on every forensics TV show ... "Of course my fingerprints were at their house, I delivered a package to them earlier this week!" Soon, though, that excuse may not be enough. Using a new technique, investigators could be better able to determine how many days ago fingerprints were left at a crime scene.Read More

New test can detect cocaine use through a single fingerprint

A team led by researchers at the University of Surrey in the United Kingdom has developed a new, non-invasive test that's able to detect cocaine use in a patient by analyzing a single fingerprint. Unlike existing tests, the new technique is able to determine whether the subject has ingested the drug, rather than just touched it.Read More

Virtual reality may find use in assessing sex offenders

People who have been charged with sexual offenses typically have to undergo psychotherapy in order to control their deviant impulses. According to researchers at the University of Montreal, virtual reality may provide the best method of determining if that therapy has indeed worked – before those offenders are released back into the public.

Wireless Yardarm Sensor monitors firearm use in real time

Anytime a police officer draws their weapon, it's likely to be a tense, confusing situation where split second decisions can be the difference between life and death. In an attempt to reduce some of the confusion, Yardarm has developed a wireless sensor that allows firearms to be tracked and monitored in real time thanks to a small electronics package that fits into the weapon's grip.

Hull-clinging robots could perform secret searches of smugglers' boats

Maritime smugglers will often hide contraband in false hulls or propeller shafts within their boats. While there are ways in which port authorities can search for such stashes, the smugglers often have time to ditch their illicit goods before those searches can be performed. However, what if there were stealthy, inexpensive, underwater hull-hugging robots that could check the boats out, without the crews even knowing they were there? That's just what a team at MIT is developing. Read More

Safelet is one alarming bracelet

Sexual violence is sadly still a problem facing (mostly) women in countries around the world. The statistics regarding the number of cases is shocking, but the effect that it has on all women, whether victims or otherwise, is likewise depressing. Safelet aims to make the world a safer place, and foster a feeling of security for people wearing this "alarming" (in both the figurative and literal senses) bracelet.Read More

Novel forensic technique identifies people by their hair

If you watch any cop shows, then you know that a person's race and gender can be determined by doing a DNA analysis of one of their hairs. Now, however, Canadian scientists at Queen's University have developed a method of obtaining that same information from hair samples, that's quicker than DNA testing and is 100 percent accurate.
