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.

Researchers identify new areas of gene regulation

Researcher Kangling Zhang at the University of California, Riverside is part of a team that has discovered a new way that yeast governs genetic expression and repression, a finding that could be repeated in cells of other organisms.

As mobile phone use rises, possibility of unseen biological impact is quietly troubling

Cell biologists are of two minds about the possible biological effects of mobile phone radiation. In the mid-1990s, studies describing possible pathological effects on tissues bombarded with low-level radio frequencies (RF) were first featured in the popular press and then discredited by scientists.

Spitting into a cup could someday be an alternative to blood testing

Researchers have identified the largest number of proteins to date in human saliva, a preliminary finding that could pave the way for more diagnostic tests based on saliva samples. Such tests show promise as a faster, cheaper and potentially safer diagnostic method than blood sampling, they say.
