Humans 2.0 - "With CRISPR, scientists can change, delete, and replace genes in any animal, including us. Working mostly with mice, researchers have already deployed the tool to correct the genetic errors responsible for sickle-cell anemia, muscular dystrophy, and the fundamental defect associated with cystic fibrosis. One group has replaced a mutation that causes cataracts; another has destroyed receptors that H.I.V. uses to infiltrate our immune system." [more inside]
The CRISPR Revolution [ungated: 1,2,3] - "Biologists continue to hone their tools for deleting, replacing or otherwise editing DNA and a strategy called CRISPR has quickly become one of the most popular ways to do genome engineering. Utilizing a modified bacterial protein and a RNA that guides it to a specific DNA sequence, the CRISPR system provides unprecedented control over genes in many species, including perhaps humans. This control has allowed many new types of experiments, but also raised questions about what CRISPR can enable." [more inside]
Reddit interviews Peter Norvig (reddit discussion) related: Seeds of AI at Google -- how the internet is shaping intelligence and learning and, in turn, the role of human culture in natural selection1,2 and why we are not living in western civilization. (via)
One of the classic arguments against evolution by natural selection is "what good is half an X?" where X is an eye, a wing or some other complex body part or system. Directly responding to the implicit challenge some researchers have been not just figuring out how X could have evolved, but actually evolving new complex machines (previously). The basic ideas are so simple that web versions (explanation and discussion) have been popping up.
Biomimetics: Design by Nature. "Burs on a dog's coat led to the invention of Velcro. That's an example of biomimetics—the young science of adapting designs from nature to solve modern problems. Now it may be coming of age."
Peter Watts on Vampire Domestication (embedded Flash video, must click to start). The mythical corporation FizerPharm ("Trust. Profit. Deniability.") share their detailed research into the evolution and possible commercial applications of Homo sapiens whedonum. You will learn: How and why the "crucifix glitch" came about. Why you should run from a blushing vampire. How many kilograms of human are needed to make one kilogram of vampire. How vampires resemble two year old humans, domestic shorthaired cats, and lungfish. And why "survival of the fittest" should be reconceptualized as "survival of the least inadequate". [more inside]
