A Colorado DNA analyst's guilty plea has reignited the JonBenét Ramsey murder case, drawing attention back to the unsolved case and prompting the father to seek DNA assistance.

Jon Zehr discovered genetic evidence of a previously unknown nitrogen-fixing bacteria in seawater samples, but the organism remained invisible under microscopes. The bacteria's existence challenged biological norms, as nitrogen-fixing enzymes typically break down in oxygen-rich environments.

Prosecutors showed a video of Tyler Robinson in court after he turned himself in for the shooting of conservative activist Charlie Kirk at Utah Valley University. The defense challenged DNA evidence linking Robinson to the murder weapon, while the roommate and romantic partner of Robinson, Lance Twiggs, provided statements under immunity.

Tyler Robinson's lawyers are challenging DNA evidence found on a towel that wrapped a rifle linked to the Charlie Kirk murder. The case centers on whether the DNA evidence is valid in connecting Robinson to the crime.

Tyler Robinson and Lance Twiggs' DNA were allegedly found on a towel and screwdriver linked to Charlie Kirk's assassination. Robinson, accused of fatally shooting Kirk during a Turning Point USA event, is facing charges including aggravated murder, while Twiggs, whose DNA also appears on the evidence, is cooperating with investigators.

Anthropologists used DNA to identify the remains of a Revolutionary War soldier who died in 1780 at the Battle of Camden, allowing his relatives to learn his name.

Investigators are searching the sewers beneath the decrepit Philadelphia home of Eugene Horsch, 44, for DNA, chemicals used to dissolve bodies, and evidence of a drug lab.

The article explains how cells divide by doubling their DNA, condensing it into chromosomes, disassembling the nucleus, and splitting into two daughter cells. This process highlights the dynamic restructuring of cellular components during division.

A study reveals that genetics influence who is most likely to experience a relationship breakdown, suggesting that DNA may play a role in romantic instability.

Caltech researchers discovered a chemical reaction involving benzene and hydrogen cyanide that could explain the formation of DNA and RNA nucleobases on early Earth and potentially Mars. The study suggests sunlight and asteroid impacts may have driven this pathway, offering a simpler explanation than previous theories.

The article discusses how the physical complexity of the human genome may challenge AI's ability to interpret DNA as a straightforward blueprint or code. It highlights that while DNA has been viewed as a genetic database containing life's secrets, its tangled physicality could confound computational analysis.

DNA from 2,000-year-old grape seeds found in Tuscany's ancient wells reveals that Roman-era vineyards in Chianti produced white fruit, forming part of the empire's agricultural network. This discovery provides the most extensive genetic history of grapevines from a single site and links ancient practices to modern winemaking.
