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.

Sea snail compound shows potential as new anti-cancer pharmaceutical

The remarkable ability of a small Australian sea snail to produce a colorful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical.

New insights into protein transport could help define strategies for treating eye disease

Many forms of vision loss stem from a common source: impaired communication between the eye and the brain. And at the root of all eye-to-brain communication are the hundreds of proteins generated by the retina's nerve cells.

New test reveals truth behind gluten-free labels

Many people have wondered whether the gluten-free labeling on their groceries was true. Now, scientists in Australia have come up with a way to identify the presence of specific glutens in rye that indicate the presence of this grain in foods labeled “gluten-free”. Gluten is already known to be present in wheat, barley and oats.

Fatty foods increase CBD absorption, finds new research

With both marijuana and alcohol being legal in the US, researchers have found that an increasing proportion of people are using both drugs in combination. However, this is a risky thing to do, says a new study. The increased risk is largely due to the overlap of effects between the two separate drugs.

Hookah smoking not a safe option, finds new study

With the decline in cigarette smoking, students have taken to other ‘safer’ forms of smoking, especially hookah smoking. However, a pioneering study shows that a single puff from a hookah exposes the smoker to as high a level of certain toxins as an entire cigarette does!
