Dopamine Biological Clock

Authors: George Rajna

In a study published Thursday in the journal Current Biology, Güler and his colleagues demonstrate that the pleasure center of the brain that produces the chemical dopamine, and the brain's separate biological clock that regulates daily physiological rhythms, are linked, and that high-calorie foods-which bring pleasure-disrupt normal feeding schedules, resulting in overconsumption. [40] Due to the advantages such as large specific surface area, adjustable pore size and tunable functionality, metal-organic frameworks (MOFs) have shown great application potential in the fields of gas adsorption and separation, catalysis, sensing and biomedicine. [39] A recent paper of J. S. Xiang et al. published in Sci. China-Phys. Mech. Astron. has demonstrated a much larger transverse figure of merit in a topological semimetal in low magnetic fields, relative to its longitudinal counterpart. [38] A new analysis of people's brain waves when surrounded by different magnetic fields suggests that people have a "sixth sense" for magnetism. [33] Measuring optical blood flow in the resting human brain to detect spontaneous activity has for the first time been demonstrated by Wright State University imaging researchers, holding out promise for a better way to study people with autism, Alzheimer's and depression.
