Building crystalline materials from nanoparticles and DNA

Nature is a master builder. Using a bottom-up approach, nature takes tiny atoms and, through chemical bonding, makes crystalline materials, like diamonds, silicon and even table salt. In all of them, the properties of the ...

Genetic code used to engineer a living protein

Yale University researchers have successfully re-engineered the protein-making machinery in bacteria, a technical tour de force that promises to revolutionize the study and treatment of a variety of diseases.

Packaging process for genes discovered

Scientists at Penn State University have achieved a major milestone in the attempt to assemble, in a test tube, entire chromosomes from their component parts. The achievement reveals the process a cell uses to package the ...

Robots learn to share, validating Hamilton's rule (w/ video)

Using simple robots to simulate genetic evolution over hundreds of generations, Swiss scientists provide quantitative proof of kin selection and shed light on one of the most enduring puzzles in biology: Why do most social ...

Mutant mouse reveals new wrinkle in genetic code

(PhysOrg.com) -- Call it a mystery with a stubby tail: an odd-looking mouse discovered through a U.S. government breeding program in the 1940s that had a short, kinky tail and an extra set of ribs in its neck – and nobody ...

Argentine ant genome sheds light on a successful pest

(PhysOrg.com) -- A research team led by scientists at the University of California, Berkeley, and San Francisco State University has unlocked the genetic code of the highly invasive Argentine ant, providing clues as to why ...

DNA repair protein caught in act of molecular theft

Scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, ...
