Researchers have solved the decades-old mystery of how stomach bacterium He...

Researchers have integrated two CRISPR-Cas9-based core processors into human cells. This represents a huge step towards creating powerful biocomputers. Controlling gene expression through gene switches based on a model borrowed from the digital world has long been one of the primary objectives of synthetic biology. The digital technique uses what are known as logic gates to process input signals, creating circuits where, for example, output signal C is produced only when input signals A and B are simultaneously present.

To date, biotechnologists had attempted to build such digital circuits with the help of protein gene switches i...

Engineered heart completely matches the immunological, cellular, biochemical and anatomical properties of the patient. In a major medical breakthrough, Tel Aviv University researchers have “printed” the world’s first 3D vascularised engineered heart using a patient’s own cells and biological materials.

Until now, scientists in regenerative medicine – a field positioned at the crossroads of biology and technology – have been successful in printing only simple tissues without blood vessels.

“This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” says...

A Cornell researcher, who is a leader in developing a new type of gene editing CRISPR system, and colleagues have used the new method for the first time in human cells – a major advance in the field.

The new system, called CRISPR-Cas3, can efficiently erase long stretches of DNA from a targeted site in the human genome, a capability not easily attainable in more traditional CRISPR-Cas9 systems...
