Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Core sugars in breast milk fuel gut and brain health beyond 12 months

Researchers reviewed 13 studies of human milk oligosaccharides (HMOs) through 24 months of breastfeeding, analyzing 4,786 samples. Six “core” HMOs remained dominant, with total concentrations plateauing after 12 months and evidence suggesting persistence into the second year.

Study: Not all dietary proteins are digested equally in the gut

As protein-rich diets become increasingly popular, a new study suggests that categorizing dietary proteins as either animal- or plant-based fails to effectively capture the source-specific differences in their composition, digestive efficiency and accessibility to the gut microbiota.

Ultra-processed foods affect sperm quality and metabolism even without extra calories

A controlled crossover trial in Cell Metabolism found that ultra-processed foods increase weight, fat mass, LDL:HDL cholesterol, and alter reproductive hormones in men, with some effects independent of calorie load. These diets also showed trends toward reduced sperm motility, shifts in pollutants, and transient inflammatory responses, highlighting risks beyond excess calories.

AI predicts designer drug structures for improved detection

How does one identify something no one has a test for? Designer drugs replicate the effects of known, illicit drugs but evade law enforcement. The chemical structure variations that help these compounds avoid detection also make them unpredictable in the body - a quality that poses serious health consequences.
