Machine learning approach significantly expands inovirus diversity

To answer the question, "Where's Waldo?" readers need to look for a number of distinguishing features. Several characters may be spotted with a striped scarf, striped hat, round-rimmed glasses, or a cane, but only Waldo will ...

Querying big data just got universal

To solve one of the key obstacles in big-data science, KAUST researchers have created a framework for searching very large datasets that runs easily on different computing architectures. Their achievement allows researchers ...

Scientists engineer unique 'glowing' protein

Biophysicists from the Moscow Institute of Physics and Technology have joined forces with colleagues from France and Germany to create a new fluorescent protein. Besides glowing when irradiated with ultraviolet and blue light, ...

New genetic engineering strategy makes human-made DNA invisible

Bacteria are everywhere. They live in the soil and water, on our skin and in our bodies. Some are pathogenic, meaning they cause disease or infection. To design effective treatments against pathogens, researchers need to ...

New CRISPR-powered device detects genetic mutations in minutes

A team of engineers at the University of California, Berkeley and the Keck Graduate Institute (KGI) of The Claremont Colleges combined CRISPR with electronic transistors made from graphene to create a new hand-held device ...

Is gene editing ethical? It depends

One of Matthew Liao's most popular papers proposes that humans could genetically engineer themselves to collectively reduce our species' carbon footprint.

Genetic engineering

Genetic engineering, recombinant DNA technology, genetic modification/manipulation (GM) and gene splicing are terms that apply to the direct manipulation of an organism's genes. Genetic engineering is different from traditional breeding, where the organism's genes are manipulated indirectly. Genetic engineering uses the techniques of molecular cloning and transformation to alter the structure and characteristics of genes directly. Genetic engineering techniques have found some successes in numerous applications. Some examples are in improving crop technology, the manufacture of synthetic human insulin through the use of modified bacteria, the manufacture of erythropoietin in hamster ovary cells, and the production of new types of experimental mice such as the oncomouse (cancer mouse) for research.

The term "genetic engineering" was coined in Jack Williamson's science fiction novel Dragon's Island, published in 1951, two years before James Watson and Francis Crick showed that DNA could be the medium of transmission of genetic information.
