A new study examines 'shoulder tapping,' where an underage person asks a stranger to purchase alcohol. Young males are the most willing to participate, with 19% of adults in this demographic agreeing to buy beer for an underage youth. This behavior can lead to serious problems, including traffic crashes and unplanned pregnancies.
The Cryogenic MALDI-FTMS technology enables unbiased view of disease by identifying proteins and biomarkers. This will aid in disease diagnosis, identification, and treatment options.
