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.

Toxic compounds found in synthetic and natural hair extensions

Chemical analysis of hair extensions uncovers hazardous substances, emphasizing the need for improved regulation and transparency in the beauty industry.

Nasal COVID vaccine boost increases IgA responses linked to variant neutralisation

Intranasal boosting after prior intramuscular COVID vaccination induced strong mucosal IgA responses in a small human cohort. These antibodies showed markedly enhanced neutralising activity against Omicron variants and evidence of immune memory reprogramming toward mucosal protection.

Parkinson's-related weight loss reflects a failure of the body's energy-producing pathways

Weight loss is a well-recognized but poorly understood non-motor feature of Parkinson's disease (PD). Many patients progressively lose weight as the disease advances, often alongside worsening motor symptoms and quality of life.

Magnesium lower fasting blood sugar in older adults

Magnesium boosts fasting glucose control in older adults with deficiency, but preventing diabetes progression may need more than just mineral correction.

Study uncovers immune trigger behind vaccine-induced immune thrombocytopenia and thrombosis

A global research collaboration of scientists from McMaster University (Canada), Flinders University (Australia) and Universitätsmedizin Greifswald (Germany) uncovered why a small number of people developed dangerous blood clots after either receiving certain COVID‑19 vaccines or experiencing a natural adenovirus infection, and the answer lies in an unexpected case of misdirected targeting by the immune system.

Early bone molecular changes signal osteoarthritis progression

Osteoarthritis often goes undetected until cartilage damage is advanced, limiting treatment options. A new study shows that molecular changes in subchondral bone occur earlier and can signal disease progression before cartilage loss.

Early biomarkers predict infections after breast reconstruction surgery

In the U.S., one in eight women will get breast cancer in their lifetime, and about half of them will have mastectomies.

Australian researchers develop a new way to target deadly, drug-resistant bacteria

Australian researchers have developed a powerful new way to target deadly, drug-resistant bacteria by designing antibodies that recognize a sugar found only on bacterial cells – an advance that could underpin a new generation of immunotherapies for multidrug resistant hospital-acquired infections.

Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

How microalgae, fish, and krill store omega-3s differently and why it matters

This study mapped how EPA and DHA are distributed across lipid classes in microalgae, fish, krill, and commercial omega-3 supplements using lipid-class–resolved analysis. It shows that lipid structure, not just total omega-3 content, differs markedly across sources and may influence their nutritional relevance.

New findings explain how lysosomal defects trigger neuronal energy failure

Together with colleagues from Stanford University, USA, researchers at the Leibniz Institute on Aging - Fritz Lipmann Institute (FLI) have, for the first time, created a comprehensive cell type-specific atlas of lysosomes in the brain, the cell organelles which are responsible for degradation and recycling processes.

Ageing slows brain protein clearance and shifts synaptic waste to microglia

Ageing slows neuronal protein degradation in mice, leading to widespread accumulation and aggregation of long-lived proteins, particularly at synapses. As neuronal clearance declines, microglia selectively accumulate synaptic proteins, suggesting a compensatory but potentially strained proteostasis pathway in the ageing brain.

Mcgill researchers find unexpected chemical contaminants in human milk samples

An interdisciplinary team including researchers at McGill University has found a range of unexpected chemical contaminants in human milk samples from Canada and South Africa.

Blood lipid–hormone ratios predict future asthma attacks years in advance

This study shows that specific ratios of circulating sphingolipids to steroids can predict the risk of future asthma exacerbations over five years with high discriminatory performance. By integrating metabolomics with longitudinal medical records, the research highlights lipid–hormone pathway imbalance as a key driver of asthma instability.

Blood metabolites reveal who will develop type 2 diabetes years before diagnosis

This large prospective study integrated blood metabolomics, genetics, and lifestyle data to identify hundreds of metabolites associated with long-term risk of type 2 diabetes in initially healthy adults. A validated 44-metabolite signature improved risk prediction beyond conventional factors, offering insights into biological pathways and opportunities for earlier, more precise prevention.

Gut microbiota analysis offers insights into how ultra processed foods affect health

To gain more knowledge about how ultra-processed food affects us, we need new research methods, claim researchers. Now they are looking to better understand our intestinal flora.

New antibody mechanisms disrupt bacterial adhesion in urinary tract infections

Pathogens can create sticky situations. When microbes invade the body to cause an infection, often one of their first lines of attack is to cling tenaciously to the surfaces of targeted human cells.

Blood metabolite profiling outperforms BMI in predicting pregnancy complications

This study shows that a blood-based metabolomic signature linked to maternal BMI predicts gestational diabetes and preeclampsia more strongly than BMI alone, particularly in late pregnancy. A subset of 16 metabolites statistically mediates the BMI–gestational diabetes association, highlighting metabolic pathways that may improve prenatal risk stratification.

New grant supports research into drug-induced brain toxicity

Important FDA-approved drugs to treat HIV and cancer can save lives, but they come with their own risks. Some drugs used clinically are known to cause neurological side effects in up to half of patients, ranging from confusion and memory problems to permanent nerve damage.

Opposing protein forces fine tune mRNA stability in human cells

A newly revealed molecular tug-of-war may have implications for better understanding how a multitude of diseases and disorders - including cancers, neurodegenerative diseases and immune disorders - originate, as well as how to potentially treat them, according to researchers at Penn State.
