    So what I'm getting from this, Random Furniture Ad, is that your claims are bogus, your product is shoddy, and most people prefer your competitors.

    Guest lecturing next week for a really cool-sounding course called Computational Biology: Genomes, Networks, Evolution. Will cover tests for natural selection. BRB, just going to check and make sure the neutral theory remains universally accepted and noncontroversial.

    We have new kittens. Cecilia and Clarence are named after a Unitarian scientist and a Universalist minister, both Massachusetts residents. Can you guess who?

    A neat clue as to how balancing selection may favor tightly linked functional genetic diversity (aka gene buddies): human variants impacting malaria resistance are significantly close to, but not within, regions of ancient polymorphisms shared with chimps.

    The (Anglican) clergy stress their role teaching basic biology facts to their communities. Educate rather than denounce traditional healers. Bishop Njovu (Zambia): (paraphrased) "Real faith healing means you pray, God gives wisdom to scientists, they produce treatments."

    Attending a panel on malaria at featuring Harvard faculty (representing both science and religion) and several African bishops. Should be a fascinating discussion.

    She Has Her Mother's Laugh is a superbly thorough tour of the meaning, mechanisms, and misues of heredity. Ends with plugging "a social form of CRISPR" - meme drive if you will - to alter the culturally inherited practices that ultimately fuel our planet's ills.

    At talk by Becky Lamason on how intracellular bacterial pathogens spread between cells. Bacterial effector proteins target host stabilizer proteins that normally promote cell-cell tension, making the junction between host cell membranes more flexible. Loose lip(id)s sink ships.
