Forensics Science Report
 | Scientists in Poland are describing how a medical imaging technique has taken on a second life in revealing forgery of an artist's signature and changes in inscriptions on paintings that are hundreds of years old. A report on the technique, called optical coherence tomography, is in ACS' Accounts of Chemical Research, a monthly journal. ...> Full Article |

 | Two researchers from the University of Salamanca have developed a procedure to enable forensic police to extract metric data from crime scenes using just a single photograph. Their proposal, published recently in the Journal of Forensic Sciences, makes it possible to reconstruct a crime scene in 3-D. ...> Full Article |
There is no quantitative standard used by the worldwide fingerprint community to determine the quantity and quality of information in an image or for the number of points of comparison required for identification. The National Institute of Justice has awarded researchers at Virginia Tech a two-year, $854,907 grant to develop a quantitative approach to measuring and establishing a standard for "sufficiency" of information available in fingerprint patterns.

 | A number of US states now use facial recognition technology when issuing drivers licenses. Similar methods are also used to grant access to buildings and to verify the identities of international travelers. Historically, obtaining accurate results with this type of technology has been a time intensive activity. Now, a researcher from the University of Miami College of Engineering and his collaborators have developed ways to make the technology more efficient while improving accuracy. ...> Full Article |
 | Computer Scientist Hany Farid has new evidence regarding a photograph of accused JFK assassin Lee Harvey Oswald. Farid digitally analyzed the iconic image of Oswald pictured in a backyard setting holding a rifle in one hand and Marxist newspapers in the other, and he says the photo almost certainly was not altered. ...> Full Article |
Try to pronounce the words "caught" and "cot." If you're a New Yorker by birth, the two words will sound as different as their spellings. But if you grew up in California, you probably pronounce them identically

 | Each of the 6.7 billion people on Earth has a signature body odor -- the chemical counterpart to fingerprints -- and scientists are tracking down those odiferous arches, loops, and whorls in the "human odorprint" for purposes ranging from disease diagnosis to crime prevention. That's the topic of an article in the current issue of Chemical & Engineering News, ACS' weekly newsmagazine.
