"This is the first time we observed individual molecules switching and acting as memory," Dr. Tour said.
In May, near the Jerome Park Reservoir in the Bronx, my sister and I observed individual flies that sometimes clumped together in large swarms, which seemed to be attracted to people and animals passing by.
By looking at correlations between the atoms' positions in hundreds of such images, the team observed individual atoms interacting in some rather peculiar ways, based on their position in the lattice.
During training, we observed individual variation in the number of sessions required to learn the task; while some fish learned within a single session (Experiment 1: Fish 3 and 4), others required longer periods of training (up to 17 sessions / 510 trials).
We aimed to examine whether commonly observed individual differences in sleep architecture and the sleep electroencephalogram reflect individual traits, which are amenable to a genetic investigation of human sleep.
Remarkably, although all ETS transcription factors bind the same DNA consensus sequence and overlapping tissue expression is observed, individual ETS transcription factors play unique roles in the development of HSCs.
The order is indeed inverted once we control for observed individual and job characteristics (column 2).
In this section we first analyze the extent to which observed individual characteristics might contribute to the achievement gap between native and immigrant students.
