DNA testing

Detectives have made an arrest in a decades-old murder case after matching DNA taken from a discarded water bottle to evidence from the killing. The breakthrough shows how genetic genealogy and modern testing techniques are being used to close cold cases, and the case is drawing wide attention as an example of new forensic methods solving old crimes.

NPR's Book of the Day is highlighting 'History by a Hair,' a book in which DNA analysis is used to address a long-standing question about Thomas Jefferson. The most famous such question is whether Jefferson fathered children with Sally Hemings, an enslaved woman at Monticello, a debate genetic evidence has fed for years. Listeners and readers are sharing the segment across public radio and book communities, with discussion of how DNA testing can settle or complicate historical controversies.

A new art exhibition in St. Louis examines the relationship between Black Americans and genetics, including DNA testing and ancestry. St. Louis Public Radio reports on the show, which uses art to explore how genetics shapes identity, family history and questions of race. Local audiences are being drawn to its blend of science and personal storytelling.

Human remains recovered from the ocean 45 years ago have been identified as a retired US Coast Guard officer who had gone missing decades earlier. The identification, reported by People, closes a long-unresolved disappearance, and the case is drawing attention for how advances in forensic testing can finally give families answers after nearly half a century.

Authorities in Texas have identified the victim of a 1983 murder through advanced DNA testing, solving part of a cold case that had gone unanswered for more than four decades. The identification offers new hope that investigators may eventually determine who was responsible for the killing.

Arkansas has introduced Rapid DNA technology at a booking station, allowing law enforcement to process DNA samples quickly during arrests rather than waiting days or weeks for lab results. Officials say the technology can speed up identifications and help connect suspects to other cases sooner. Local coverage highlights it as a step toward modernising booking procedures in the state.

The Spitball Show released a new episode discussing four startup concepts: a 90/10 revenue split model, a DNA-testing service applied to shirts, movie release windows running through libraries, and a Fiverr-style marketplace for video game assets. The episode features a guest named Kirk and walks through each pitch with timestamps covering topics like Render Bender and the 90/10 model.

An in-depth description of pharmacogenomics, the field studying how a person's genetics affect their response to drugs, has drawn attention. The science underpins personalised medicine, where prescriptions are tailored to individual DNA profiles to improve effectiveness and reduce adverse reactions. Interest in the topic reflects growing public curiosity about how genetic testing is shaping medical treatment.

SpaceX's Starship program is being described as a winning bet, even as reports highlight a cultural and institutional clash between SpaceX and NASA. The story frames SpaceX's aggressive, risk-tolerant development approach against NASA's more cautious engineering culture, arguing that the gamble on rapid Starship testing has paid off despite tensions with the space agency.

The Arkansas State Crime Lab has introduced rapid DNA technology, a system that can process DNA samples far faster than traditional laboratory methods. Local outlets across the state, including KNWA, KARK and FOX16, are covering the rollout. Faster results could speed up criminal investigations and reduce backlogs, though details on cost and implementation have not been widely reported.
