British Scientists Seek Permission to Genetically Modify Human Embryos

Just five months after scientists in China made history by modifying the germline of human embryos, a research team in the U.K. is requesting permission to do the same, but strictly for research into infertility. Given recent calls for a moratorium on such research, the decision is likely to set a precedent for future… »9/18/15 4:30pm9/18/15 4:30pm

Legos Are Surprisingly Effective at Explaining Synthetic Biology

The emerging discipline of synthetic biology is poised to change many aspects of our lives, from the production of medicines and bio-fuels through to genetic engineering and the development of completely new biological systems. It’s a technologically daunting prospect, but this video from Grist uses Legos and… »8/04/15 1:40pm8/04/15 1:40pm

You Can Thank Genetic Engineering For Your Delicious Cheese

It used to be that making cheese meant killing cows. Young cows, specifically—a few days old, at most. The stomach of an unweaned calf produces enzymes that turn liquid milk into good, hard, flavorful cheeses like Parmesan and Cheddar. These enzymes, called rennet, are secreted by mucous membranes that line the calf’s… »6/15/15 2:57pm6/15/15 2:57pm

​Scientists engineer worms to live the equivalent of 500 human years

In an experiment that even caught the researchers by surprise, nematode worms had their lifespans increased by — get this — five times. By tweaking two longevity-related genes, the researchers created an unexpected feedback effect that radically amplified lifespan. The technique could eventually be used to treat… »12/16/13 5:20pm12/16/13 5:20pm
