Europe has a new mosquito problem, but it may not be the one you think

A scoping review of 91 studies, combined with a workshop involving 41 experts from six European countries, mapped the spread, biology, surveillance challenges, and potential disease relevance of the invasive mosquito Aedes koreicus. The researchers identified major gaps in species identification, vector competence, ecology, genetics, and long-term surveillance that must be addressed as the cold-tolerant mosquito expands across Europe.

Nanoparticle flu vaccine design could pave way for broader protection

Influenza viruses constantly shapeshift to evade recognition by the immune system. This shapeshifting occurs in critical proteins like hemagglutinin (HA), which controls how the virus attaches to human cells before entering them.

Coffee’s link to Parkinson’s risk may depend on how your body handles caffeine

In 435,551 UK Biobank participants followed for a median of 15.7 years, overall coffee consumption was not associated with Parkinson’s disease risk, but the relationship differed significantly according to CYP1A2 genotype. Lower risk was observed with low-to-moderate coffee intake among fast-metabolizer AA carriers, while higher intake was associated with increased risk among AC and CC carriers, although the observational findings do not establish causality and sex-specific patterns require cautious interpretation.

Alcohol-related liver cancer deaths were falling. Then the trend reversed during the COVID-19 pandemic

A global analysis of GBD 2023 data found that alcohol-attributable liver cancer mortality increased modestly from 1990 to 2023, while mortality from alcohol-attributable cirrhosis, alcoholic cardiomyopathy, and alcohol use disorders declined. Liver cancer mortality shifted from a pre-pandemic decline to an increase during 2020–2023, particularly among women, although the researchers cautioned that the ecological analysis cannot establish that pandemic-related changes caused the reversal.

The global toll of snakebite may be much bigger than we thought

A global literature review and geostatistical modeling study estimated the burden of snake envenoming and deaths across countries, accounting for differences in surveillance, underreporting, socioeconomic conditions, and environmental factors. The analysis highlights major gaps in epidemiological data and provides updated country- and regional-level estimates to help guide prevention, antivenom access, surveillance, and healthcare resources.

Mizzou researchers explore first drug treatment for aortic valve calcification

University of Missouri researchers are advancing a promising new approach to treating a serious heart condition that affects millions of older adults worldwide.

Cellular atlas offers clues to childhood Crohn’s treatment response

Researchers have created a detailed map of childhood Crohn's disease before and after treatment to help understand progression of the disease.

Smartwatches may overestimate calories burned during exercise

Smartwatches can significantly overestimate how many calories people burn during exercise, and their calorie estimates become less accurate as body fat increases, according to a new Florida International University study.

Study uncovers cause of abnormal breathing in Rett syndrome

Hyperventilating. Breath holding until they turn blue. This abnormal breathing is frequent and disturbing in people with Rett syndrome, a rare genetic disease.

Certain diabetes patients face higher ketoacidosis risk with SGLT2 drugs

Patients with type 2 diabetes who have high blood glucose levels, low body weight, or a history of ketoacidosis are at increased risk of developing this serious condition when treated with so-called SGLT2 inhibitors.

Evidence remains insufficient to support routine use of lumbar braces for chronic low back pain

A new Cochrane review finds very low-quality evidence on lumbar supports for chronic low back pain, meaning that no strong recommendations can be made either for or against their use.

Flavorings, colors and sweeteners emerge as UPF markers linked to depression risk

A prospective UK Biobank study of 171,818 adults found that greater estimated exposure to foods containing flavorings, coloring agents, and sweeteners was dose-dependently associated with a higher risk of incident depression over 10.7 years. The findings suggest that specific markers, rather than ultra-processed foods uniformly, may help explain associations between UPF consumption and depression risk.

Researchers found one childhood behavior linked to folic acid use before pregnancy

Researchers analyzed 646 children aged 2–8 years and their 563 mothers to examine whether maternal folic acid supplementation before conception was associated with childhood behavioral difficulties. Preconception supplementation was associated with a 34% lower risk of peer relationship problems, while no significant associations were found for total behavioral difficulties, emotional, conduct, hyperactivity/inattention, or prosocial problems.

Seafood at breakfast stood out in a study of nearly 6,000 adults

Researchers analyzed dietary and sleep data from 5,975 Japanese adults to examine whether seafood, EPA, and DHA intake at different meal occasions was associated with chronotype and social jetlag. Higher intake at breakfast showed the strongest association with earlier sleep timing and less social jetlag, although the cross-sectional design cannot establish whether dietary timing influences sleep patterns or vice versa.

Researchers identify a previously unknown mechanism that can drive cancer cachexia

Researchers at Helmholtz Munich, the Heidelberg Faculty of Medicine at Heidelberg University, the German Center for Diabetes Research (DZD) and the Technical University of Munich (TUM), have identified a previously unknown mechanism that can drive cancer cachexia – a wasting process in the body that primarily affects muscle and fat tissue.

NIH grant funds research on environmental triggers for sickle cell disease

The Icahn School of Medicine at Mount Sinai has received a $4.1 million grant from the National Heart, Lung, and Blood Institute, part of the National Institutes of Health, to study how everyday exposures affect the health of people with sickle cell disease.
