In line with the goal of limiting health risk behaviors in adolescence, a growing literature investigates whether individual differences in functional brain responses can be related to vulnerability to engage in risky decision-making.

Lasers have caused revolutionary changes in many fields of science and technology. Since 1960, six orders of magnitude, from 10 to 10 seconds, have been added to time-resolved observation of fast phenomena, which makes ultrafast research grows rapidly among materials science, biology, and chemistry. The use of these ultrashort high-power pulses went hand-in-hand with their development and alrea...
