Pure novelty spurs the brain
...eurobiologists have known that a novel environment sparks
exploration and learning, but very little is known about whether the brain really prefers novelty as such. Rather, the major "novelty center" of the brain--called the substantia nigra/ventral tegmental area (SN/VTA)--might be activated by the unexpec...
Nanowires can detect molecular signs of cancer, scientists find
...ale proteins come into contact with a receptor, it sparks
a momentary change in conductance that gives a clear indication of the marker's presence. The detectors differentiate among various cancer markers both through the specific receptors used to snag them and because each binds its receptor for a charact...
Light therapy may combat fungal infections, new evidence suggests
...be an important and previously overlooked cue that sparks
infection, the researchers said. The discovery in the human pathogen Cryptococcus neoformans further suggests that light therapy, in combination with anti-fungal drug treatments, might offer an effective method to combat a variety of fungal infectio...
