Household dust harbors forensic DNA info

Finding DNA in household dust could offer a way to help investigators get leads in difficult-to-solve criminal cases.

It’s possible to retrieve forensically relevant information from human DNA in household dust, a new study finds.

After sampling indoor dust from 13 households, researchers were able to detect DNA from household residents over 90% of the time, and DNA from non-occupants 50% of the time. The work could be a way to help investigators find leads in difficult cases.

Specifically, the researchers were able to obtain single nucleotide polymorphisms, or SNPs, from the dust samples. SNPs are sites within the genome that vary between individuals—corresponding to characteristics like eye color—that can give investigators a “snapshot” of the person.

“SNPs are just single sites in the genome that can provide forensically useful information on identity, ancestry, and physical characteristics—it’s the same information used by places like Ancestry.com—that can be done with tests that are widely available,” says Kelly Meiklejohn, assistant professor of forensic science and coordinator of the forensic sciences cluster at North Carolina State University and corresponding author of the study in the Journal of Forensic Sciences.

If you’re not amazed by the stars on a clear night then we won’t work.

future me is wearing vintage dior to ballets & operas, ordering thousands of dollars worth of la perla, and slathering herself in crème de la mer. she’s living her best life. she finds any excuse to celebrate life by drinking glasses of chilled moët & chandon rose imperial champagne while binge watching grace kelly movies. every night she drowns herself in silk bedsheets while wearing baby pink olivia von halle ‘coco’ pyjamas. there are fresh arrangements of roses (from all her admirers) & peonies (which she picked up from the farmers market) in every room. she is utterly and completely happy. i can’t wait to be her.
