Things you'll want in your next book

 

1. Scientists have developed a new sophisticated fluorescent ink that can be used as a multicolored barcode, a tool that will aid consumers with identifying and verifying authentic products. A quick scan with a cell phone and you’ll instantly know if what you’re buying is the real thing, or a cheap imitation.

2. FINDER (Finding Individuals for Disaster and Emergency Response), a new device used for locating buried victims, is now available for the commercial market. FINDER uses radar to locate and pinpoint heartbeats.

3. Hybridsil, a new Kevlar-based material used to manufacture firefighters’ gloves, offers enhanced dexterity, and much-improved heat and water resistance. The new material also provides an added protection against punctures and lacerations.

4. The Office of Naval Research (ONR) is now using functional MRI machines to determine how well working canines respond to verbal praise, petting, and snack treats. The purpose of the fMRI testing is to measure brain activity by detecting changes in blood flow caused by the animals’ responses to the stimuli. The ONR is also studying how long canines remember certain odors and how they process them.

5. Presumptive drug test kits used in the field by law enforcement have been found to give false positive results when used to test common household items, such as coffee, aspirin, and chocolate. Even soap has been “positively” identified as the date-rape drug GHB. Candy showed up as meth. And mints were identified as crack cocaine. Of course, in criminal cases laboratory tests performed by forensic scientists are always conducted to confirm field results.

The problem with the false positives, if negated by lab tests, is that innocent people have been detained and even jailed due to faulty test kit results. Remember, though, convictions for illegal drug possession are not based on presumptive drug testing conducted street-side by cops. Instead, officers use the field tests/kits only to help determine probable cause for arrest.

6. Human microbial signatures—skin-associated bacteria—can be identified on various surfaces, such as computers, shoes, clothing, cell phones, flooring, etc. Therefore, it is possible that law enforcement may pinpoint a suspect’s previous whereabouts by examining bacteria found at crime scenes.

7. Altering fingerprints CAN beat the system. Yes, criminals have escaped producing a “match” by altering their print patterns in some way. The most common and effective means of changing print patterns is to cut a straight vertical line through the print(s). The method can prevent an automatic hit returned by an automated ID system. Sanding, burning, biting, and other methods of cutting are far less effective.
