            In this week’s episode of “TechKnow,” we highlight the latest advances in forensic technology that are helping law enforcement agencies identify suspects and solve crimes with increasing accuracy. Cases that were left cold for years are being revisited with fresh eyes—and, more importantly, fresh technology. Where we have seen some of the largest leaps in the past decade is in the analysis of contact trace DNA or “Touch DNA.” A person sheds about 400,000 skin cells per day, and with smaller and smaller samples required to make an accurate match, it is becoming more difficult to commit a truly untraceable crime.
But in order to match crimes up with criminals based on trace amounts of DNA, it also requires expanding and centralizing local, state, and national DNA databases used by law enforcement.
Last June, 
the Supreme Court ruled 5-4 that it was constitutional to take DNA swabs from people who have been arrested for “serious crimes” without getting a warrant or waiting for a conviction. These DNA samples can be added to a database and can be used to...

[OHSU News/Christine Torres Hicks]
On September 30th, a team of 21 scientists from Oregon Health & Science University (OHSU) published a significant paper in Nature Communications, with a scientifically accurate but, to many, somewhat abstruse headline:
Induction of experimental cell division to generate cells with reduced chromosome ploidy
The lead authors were Shoukhrat Mitalipov, recently described here as “a push-the-envelope biologist,” and his long-term colleague Paula Amato. (Recall that in July the pair had co-published with...

            Before dawn on a March morning, Doug Whitney walked into a medical center 2,000 miles from home, about to transform from a mild-mannered, bespectacled retiree into a superhuman research subject.
First, a doctor inserted a needle into his back to...

            Consider, if you will, the translucent blob in the eye of a microscope: a human blastocyst, the biological specimen that emerges just five days or so after a fateful encounter between egg and sperm. This bundle of cells, about the size of...
