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.

New review highlights spatial technologies in advanced brain mapping

Understanding how molecular changes shape brain function and disease requires more than measuring genes in bulk tissue.

New framework standardizes selenosugar research and selenium metabolism studies

Selenosugars are the major urinary metabolites responsible for the physiological excretion of selenium. Understanding selenium metabolism relies on accurately detecting and identifying selenosugars.

Sprint exercise sends a very different molecular signal through the body

Sprint-interval exercise triggers a much larger and faster shift in circulating proteins and metabolites than moderate-intensity exercise, revealing distinct patterns of predicted communication between organs. The findings suggest that exercise intensity shapes systemic molecular signaling, with skeletal muscle and adipose tissue emerging as potential source and target tissues linked to cardiometabolic health.

A study of 60 popular Chinese teas found reassuring results and one important warning

Researchers analyzing 60 best-selling online teas in China found that concentrations of six harmful elements remained within Chinese national limits and modeled noncarcinogenic risks were below concern thresholds.

Early-life stress rewires brain epigenetics to heighten sensitivity to future stress

. Early-life stress increased SETD7 and H3K4me1 in the ventral tegmental area of mice, creating an epigenetically primed state that heightened later transcriptional, neuronal, and behavioral responses to stress. Reducing Setd7 during development lowered H3K4me1 and weakened these stress-sensitizing effects, identifying a mechanism that may help explain how early adversity leaves lasting biological effects.

Newly discovered protein pathway limits spinal cord injury damage

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.

Researchers discover smart molecular glue that activates inside oxidative cancer cells

Investigators at Dana-Farber Cancer Institute have developed a platform for systematically discovering molecular glues that could become protein degradation drug candidates.

Severe COVID-19 reactivates dormant viruses and may leave a lasting viral signature

A longitudinal study of 1,154 hospitalized COVID-19 patients found widespread reactivation of chronic Herpesviridae and Anelloviridae, with distinct viral patterns linked to disease severity, inflammation, and clinical outcomes. Anelloviridae also persisted during convalescence and were associated with physical deficits in long COVID, although the study did not establish causation.

Blood filtration method helps clear circulating lipids and toxic microplastics

The machine is not new. Some version of it has run in hospital treatment rooms for about four decades, drawing blood from one arm, separating out the plasma, passing it across a filter or an adsorber, and returning it to the other arm.

New blood test could save millions through early tuberculosis detection

A new study presented today at ADLM 2026 in Anaheim, California found that a simple blood test could accurately identify tuberculosis (TB) - a leading cause of death worldwide - among patients with varying degrees of exposure to the disease.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

Spermidine boosts key cellular processes linked to aging in early research

This review finds that spermidine supports autophagy, mitochondrial function, and healthspan in experimental models, while observational studies link higher dietary intake to lower mortality. However, human trials have produced limited and mixed results, leaving its clinical role in healthy aging unresolved.

Stuffed toys can release short-chain PFAS into saliva, study finds

Researchers tested 18 stuffed toys and found that all released at least one targeted PFAS into artificial saliva under mouthing-relevant conditions, with PFHxA driving much of the variation between products. Modeled intake of the four PFAS covered by EFSA’s group tolerable weekly intake remained below that benchmark, but some high-PFHxA toys had reduced margins of exposure, and water rinsing produced mixed results.
