  • Anti-CRISPR proteins decrease off-target side effects of CRISPR-Cas9

    CRISPR-Cas9 gene editing is based on a tactic bacteria developed to protect themselves from viruses.  #Research now shows that the countermeasure viruses came up with — inhibitory proteins referred to as anti-CRISPRs — can be used to improve CRISPR-Cas9 as a gene-therapy tool, decreasing off-target gene editing that could...
  • Cities drive animals and plants to evolve

    Ever seen a raccoon unlatch a garbage can in search of leftovers? Or shimmy across power lines to get from one rooftop to another? If so, you’ve witnessed an animal adapting its behavior to city life. That’s been going on since people started building cities thousands of years ago....
  • Scientists Hack a Human Cell and Reprogram It Like a Computer

    CELLS ARE BASICALLY tiny computers: They send and receive inputs and output accordingly. If you chug a Frappuccino, your blood sugar spikes, and your pancreatic #cells get the message. Output: more insulin. But cellular computing is more than just a convenient metaphor. In the last couple of decades, biologists...
  • Scientists make giant leap in age-old pursuit of longer, healthier life

    Scientists have found a way to reverse the ageing process, extending the lifespan of mice by 20 per cent and raising the prospect of an anti-ageing treatment for humans within a decade. The discovery has attracted the attention of US space agency #Nasa , which is keen to protect...
