Supernova Flashes and Silver Linings

New research from the Weizmann Institute of Science reveals that “cells in our brain form little hexagonal grids that keep us oriented, map-like, in our surroundings.” Weizmann’s resident blogger describes this finding as “a pyrotechnic flash of insight that changes how we understand the brain to work.” Game developers delight; this discovery shows “that you…

Genetic Drifters

On Pharyngula, PZ Myers criticizes the stubborn obfuscations of Michael Behe, who refuses to yield his illogical calculations. Behe says (rightly) that a certain mutation necessary for drug resistance in the malaria parasite has about a 1 in 1020 chance of occurring. But the mutation is also detected in 96% of malaria patients who respond…

On Life Lines, Dr. Dolittle writes “Some researchers suggested that perhaps smaller animals developed more oxidative stress as a result of having higher metabolisms. Others proposed that perhaps larger…

Scientists use a ‘gene gun’ to insert a gene from a flowering plant called rockcress into the cells of wheat seeds. The genetically modified wheat became more resistant to a fungus called take-all, which in real life can cause “a 40-60% reduction in wheat yields.” T-cells from six HIV+ patients were removed from their bodies,…
