Genetic mutation could, if altered, boost FluMist vaccine effectiveness, research suggests

Researchers at Johns Hopkins Bloomberg School of Public Health have discovered a genetic mutation in the FluMist intranasal flu vaccine that has the potential to be altered to enhance its protective effect. The mutation reduces virus production, but reversing it makes the virus more active and induces a stronger immune response.

Advances in MALDI mass spectrometry within drug discovery

This special issue highlights innovations in MALDI mass spectrometry for characterizing proteomes, detecting analytes, and screening non-covalent binding of small molecules to target proteins. MALDI imaging is used to study diseases and therapeutics, including the distribution of glycosphingolipids in a Gaucher Disease model mouse brain.

Marriage may help stave off dementia

A synthesis of 15 studies found that married people had a lower risk of developing dementia compared to lifelong singletons and widowers. The researchers suggest that marriage may promote healthier lifestyles and social engagement among couples, which can contribute to a lower risk of dementia.

Removing chemical used to make Teflon-like coatings has led to fewer low birth weights and less brain damage

A new NYU report reveals that the phase-out of Teflon-like coatings, which contain PFOA, has led to a significant decrease in low-birth weight babies and related brain damage. The study estimates that this shift has saved over $13 billion in healthcare costs and improved educational prospects for thousands of children.

Stem cells in intestinal lining may shed light on behavior of cancer cells

Scientists studied how intestinal epithelial stem cells respond to varying glucose levels, discovering a switch from renewal to growth mode triggered by higher glucose. This finding has implications for understanding cancer cell proliferation and developing new therapeutic strategies.

Male trout are now real males again

Researchers at the University of Southern Denmark found that widespread feminization among male brown trout in Danish streams had completely disappeared between 2004 and 2016. The improvement was attributed to better wastewater treatment practices, particularly the connection to municipal wastewater treatment plants.

Long-term logging study demonstrates impacts on chimpanzees and gorillas (Republic of Congo)

A recent study published in Biological Conservation highlights the effects of selective logging on great ape populations before, during, and after timber extraction. The research found that western lowland gorillas avoided areas during logging but returned after it passed through, while chimpanzees were less likely to return to their n...

Worried about holiday weight gain? Your scale isn't giving you the whole picture

A new study used MRI imaging technology to plot diverse changes in body organ fat storage pools during 18 months of Mediterranean/low-carb and low-fat diets, with and without moderate physical exercise. The results showed that even with modest weight loss, the Med/LC diet was significantly superior to a low-fat diet in reducing some fa...

Neuroimaging of soccer fans' brain reveals neural basis of ingroup altruistic motivation

Researchers used functional magnetic resonance imaging to investigate the neural basis of team-related altruism in soccer fans. The study found that brain areas involved in decision-making and values, such as the medial orbitofrontal cortex, showed increased activity when donations were targeted to fans of the same soccer club.

Parental diet affects offspring immunity: Meta-analysis

A meta-analysis of hundreds of studies found a close relationship between parents' diet and offspring immunity across various animal species. The study suggests that poor nutrition can negatively impact disease resistance and that the effects of a parental diet can be inherited and maintained in offspring even on a normal diet.

Price changes for seven foods could save thousands of lives per year, study says

A new study suggests that altering prices of seven dietary items could prevent an estimated 23,000 deaths per year in the US. The study found that subsidies for healthy foods and taxes on unhealthy foods could reduce deaths from stroke, diabetes, and cardiovascular disease, especially among Americans with lower socioeconomic status.

Ambush in a petri dish

A team of researchers from Friedrich Schiller University Jena and the Leibniz Institute for Natural Product Research and Infection Biology has made a groundbreaking discovery about the chemical communication between algae and bacteria. The study reveals that a specific lipopeptide, orfamide A, plays a central role in this process.

Flip side of innovation: What causes doctors to scale back on the use of medical practices

Researchers at The Dartmouth Institute found that physicians with more experience and certain specialties tend to slow the use of carotid revascularization procedures. Despite evidence showing these procedures don't benefit older or symptom-free patients, decline rates remained inconsistent across specialties.
