Quantum mechanics could explain why DNA can spontaneously mutate

The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modeling, a team of physicists and chemists at the University ...

The women scientists forgotten by history

French doctor and researcher Marthe Gautier, who died over the weekend, was one of a long line of women scientists who greatly contributed to scientific discovery only to see the credit go to their male colleagues.

Dynamic twists and loops can enable DNA to modulate its function

When people think of DNA, they visualize a string-like double helix structure. In reality, the DNA double helix in cells is supercoiled and constrained into loops. This supercoiling and looping are known to influence every ...

Biosynthesis pathway of a new DNA nucleobase elucidated

DNA is composed of nucleobases represented by the letters A, T, G and C. They form the basis of the genetic code and are present in all living beings. But in a bacteriophage, another base, represented by the letter Z, exists. ...

New approach can add diversity to crop species without breeding GMOs

Breeding better crops through genetic engineering has been possible for decades, but the use of genetically modified plants has been limited by technical challenges and popular controversies. A new approach potentially solves ...

DNA structure itself is involved in genome regulation

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information. When genes must be accessed for transcription, the DNA double ...

Dynamic 3-D printing process features a light-driven twist

The speed of light has come to 3-D printing. Northwestern University engineers have developed a new method that uses light to improve 3-D printing speed and precision while also, in combination with a high-precision robot ...
