Tiny tweaks in DNA folding can have big effects. A study from Umeå University shows that even the most subtle changes in DNA's shape have an important influence on gene activity and energy production.

The trial of a man accused of killing his husband in Marion County and trying to cover it up entered its third day on Wednesday

Rogue DNA rings known as ecDNA may hold the key to cracking glioblastoma’s deadly resilience. Emerging before tumors even form, they could offer scientists a crucial early-warning system and a chance to intervene before the disease becomes untreatable.

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein complex called cohesin until they are pulled to opposite poles of the cell in a miniature game of tug of war.

Ryan Routh's assassination attempt trial continues with new digital forensic evidence that prosecutors say show anti-Trump messages and DNA results tying him to key items.

A traditional cassette tape holds roughly 10 to 12 songs on each side, but 328 feet of this DNA cassette tape could hold the same amount of data in over 3 billion songs. The prototype’s total capacity is 36 petabytes of data, the same size as 36,000 terabyte hard drives.

Malaria is one of the world's most widespread and deadliest parasitic diseases. But some people may have natural protection thanks to DNA inherited from an extinct group of archaic humans known as the Denisovans.
