Turning cells into computers with protein logic gates

The same basic tools that allow computers to function are now being used to control life at the molecular level. The advances have implications for future medicines and synthetic biology.

Physical force alone spurs gene expression, study reveals

Cells will ramp up gene expression in response to physical forces alone, a new study finds. Gene activation, the first step of protein production, starts less than one millisecond after a cell is stretched—hundreds of times ...

Genome variation gives insight into coronavirus spread

As SARS-CoV-2 has spread around the world, its transmission rate has varied alongside variations in its genome, according to researchers at the University of California, Davis. Surveillance of the virus genome may help public ...

Researchers solve structure of 'inverted' rhodopsin

Researchers from the Moscow Institute of Physics and Technology, working with Spanish, French and German colleagues, have determined and analyzed the high-resolution structure of a protein from the recently discovered heliorhodopsin ...

Scientists discover a new class of taste receptors

Evolution is a tinkerer, not an engineer. "Evolution does not produce novelties from scratch. It works with what already exists," wrote Nobel laureate François Jacob in 1977, and biologists continue to find this to be true.

Genetic self-activation maintains plant stem cells

Branching allows plants to occupy space in three dimensions, an innovation considered essential for their adaption. Stem cells are key to this process because they promote the establishment of new growth axes. But where do ...
