"About 200 femtoseconds after you started reading this line, the first step in actually seeing it took place. In the very first step of vision, the retinal chromophores in the rhodopsin proteins in your eyes were photo-excited and then driven through a conical intersection to form a trans isomer [1]. The conical intersection is the crucial part of the machinery that allows such ultrafast energy flow. Conical intersections (CIs) are the crossing points between two or more potential energy surfaces."

Nuclear Fusion

Today we have 3 short postings on recent happenings in Fusion research.
Nuclear fusion is the power that drives our sun and thus our life.
Supporters of nuclear fusion argue that it has the potential to be a safe and
sustainable source of energy that does not produce any greenhouse-gas
emissions or long-lived nuclear waste. A fusion reactor would need just
100 grams of deuterium and 3 tons of natural lithium to produce a power
output of 1 GigaWatt, which is equivalent to a large power station
[lithium is needed to generate tritium].
So, follow our 3 postings below:
