  • Polyps will let unrelated 'others' fuse to them and share tissue, scientists discover
    on July 12, 2018 at 2:04 pm

    Scientists discovered that polyps have no qualms about treating a nonrelated individual like part of the family. This goes way beyond sharing meals or even a roof. Polyps of the marine hydrozoan Ectopleura larynx allow nonrelated individuals to fuse their bodies to the familial colony and share what is essentially skin and a stomach. […]

  • New tech for controlling genetic inheritance and genome engineering
    on February 6, 2018 at 3:03 pm

    In 2015, biologists developed a breakthrough technology known as "active genetics," which results in parents transmitting a genetic trait to most of their offspring (instead of 50 percent receiving the trait under standard inheritance). Immediate targets of active genetics included gene-drive systems for immunizing mosquitoes against vector borne diseases such as malaria. Researchers also proposed using active genetics for a variety of other potential human health and agricultural benefits. […]
