ScienceDaily (May 17, 2012) — Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases.
ScienceDaily (May 17, 2012) — Fool me once, shame on you. Fool me twice, shame on my parahippocampal gyrus. Scientists at the Virginia Tech Carilion Research Institute have found that suspicion resides in two distinct regions of the brain: the amygdala, which plays a central role in processing fear and emotional memories, and the parahippocampal gyrus, which is associated with declarative memory and the recognition of scenes.
ScienceDaily (May 17, 2012) — One-letter switches in the DNA code occur much more frequently in human genomes than anticipated, but are often only found in one or a few individuals.
ScienceDaily (May 17, 2012) — Pollination could be a chaotic disaster. With hundreds of pollen grains growing long tubes to ovules to deliver their sperm to female gametes, how can a flower ensure that exactly two fertile sperm reach every ovule? In a new study, Brown University biologists report the discovery of how plants optimize the distribution of pollen for successful reproduction.
ScienceDaily (May 18, 2012) — Water is the most abundant and one of the most frequently studied substances on Earth, yet its geometry at the molecular level -- the simple two hydrogen atoms and one oxygen atom, and how they interact with other molecules, including other water -- has remained somewhat of a mystery to chemists.
