A voltage difference is detected in the “generator” part of individual water‐filled SWNTs when a current is applied on their “motor” part. It is suggested that the measured voltage difference reveals a newly induced electromotive force, which is generated by a water flow inside the SWNT. The water molecules in the nanotube channel are in turn dragged to flow by the current applied on the “motor” part.

Excessive alcohol consumption is one of the main causes of death and disability worldwide. Alcohol consumption is a heritable complex trait. We conducted a meta-analysis of genome-wide association studies (GWAS) of gram/day (g/d) alcohol consumption in UK-Biobank, AlcGen and CHARGE+ consortia accumulating 480,842 people of European descent to decipher the genetic architecture of alcohol intake. We identified 46 novel, common loci, and investigated their potential functional significance using magnetic resonance imaging data and gene expression studies. Our results identify genetic pathways associated with alcohol consumption and suggest shared genetic mechanisms with neuropsychiatric disorders including schizophrenia.
