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.

Study reveals bile as reservoir for microplastics in humans

Plastic pollution has become one of the defining environmental issues of modern life, and microplastics are now known to enter the body through food, drink, and air.

GC product division celebrates 70th anniversary, European and world premieres underscore progress in laboratory analytics

Today, analytica opens its doors in Munich from March 24th to 27th. Shimadzu, a global supplier of analytical measurement and testing equipment, is once again present at the world's leading trade fair – and delighted to be celebrating another anniversary so soon after its 150th birthday last year: the 70th anniversary of its gas chromatography (GC) product line.

The molecular mechanism that turns cool temps into nerve signals

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" signal to your brain.

New dual blood test reduces false positives in Alzheimer's screening

Alzheimer's disease is characterised by the accumulation of two proteins in the brain: amyloid-beta and tau.

Study finds GLP-1 medicines cut fat while preserving muscle function

Researchers found that GLP-1 medicines caused weight loss mainly through fat reduction, with only modest decreases in absolute muscle mass and no disproportionate loss of muscle function. In mice, physical performance improved, while in a small 12-week human pilot trial, strength was preserved despite reduced thigh muscle size.

New approach tracks metabolic fingerprints of tuberculosis-infected human cells

Researchers from King's College London and the University of Surrey have developed a new technique to measure the content of individual human cells infected with bacteria that model tuberculosis – and it is already revealing biological changes that conventional analysis would miss.

Blood protein structure changes may enable earlier detection of Alzheimer’s

Advanced proteomics and AI reveal blood protein changes, offering insights into early Alzheimer's detection and differentiation from mild cognitive impairment.

Swapping red meat for plant-based meat rapidly lowers a key heart risk metabolite, trial finds

A randomized crossover trial found that replacing red meat patties with processed plant-based meat alternatives for six days significantly lowered circulating trimethylamine N-oxide (TMAO), a gut-derived metabolite linked to cardiovascular risk. The plant-based phase also produced modest reductions in cholesterol markers but slightly increased weight and NT-proBNP, possibly due to higher sodium intake.

Rapid Novor receives Ontario Ministry of Health provisional license for EasyM® blood-based MRD test for multiple myeloma

Rapid Novor Inc., a Canadian biotechnology leader, announced today that its diagnostic laboratory has received a provisional license from the Ontario Ministry of Health (MOH) for its EasyM® assay, enabling the company to begin testing patients in Canada.

Specific gut bacteria may signal long-term risk of heart and metabolic disease

Researchers analyzed gut microbiome profiles from 4,792 adults in the HELIUS cohort and tracked cardiometabolic outcomes over time to determine whether specific microbes predict disease risk. Certain microbes were linked to higher or lower cardiovascular risk, while plant-derived microbial metabolites suggested potential diet–microbiome interactions influencing heart health.

Bruker advances Functional Proteomics 2.0 with timsOmni™ mass spectrometry proteoform analysis for deeper insights into disease biology

Bruker Corporation today announced new advancements to enable Functional Proteomics 2.0 workflows on the timsOmni™ mass spectrometer to enable disease researchers to move beyond canonical protein lists toward biologically or pathologically functional proteoforms and PTM-resolved peptide variants.

Researchers show red blood cells drive better glucose tolerance at high altitude

Chronic hypoxia improves glucose tolerance in mice through insulin-independent mechanisms, with red blood cells acting as a major systemic glucose sink. Increased erythrocyte production and altered glycolytic flux help reduce circulating glucose while supporting oxygen delivery to tissues.

Blood test models predict when Alzheimer’s symptoms may start years in advance

Researchers developed plasma p-tau217–based clock models that estimate when cognitively unimpaired individuals with Alzheimer’s pathology may develop symptomatic disease. The models predicted symptom onset within about three to four years and may help improve clinical trial selection while remaining unsuitable for individual clinical decisions at present.

Scientists uncover nanoplastics in brain tissue and question their role in neurological disease

Emerging evidence suggests nanoplastics accumulate in human tissues including the brain and may contribute to neuroinflammation and neurodegenerative disease pathways. However, causality, exposure routes, and long-term health effects remain uncertain and require coordinated research.
