Kids are full of surprises, right down to the coded biological programs they inherit, which may contain subtle chemical reminders of their parents' lifestyles.
Cell lines are standard tools in biomedical research, and yet when it comes to their genetic identity, they are remarkably unstable. That volatility comes with their defining trait—immortality.
The honeybee brain is dynamic and full of surprises. For instance, much like the human brain, its neurons not only modulate their activity in response to sensory stimuli but also alter their gene and protein expression patterns—changes that in bees are so dramatic as to essentially rewire the brain.
The translucent bell-shaped figure pumps rhythmically upward through the water, the rise and fall of its body almost identical to that of the moon jelly, Aurelia aurita .
In a study published in late 2011 in Nature , Stanford University geneticist Anne Brunet and colleagues described a series of experiments that caused nematodes raised under the same environmental conditions to experience dramatically different lifespans.
