A study of ayahuasca users found a mental health pattern researchers cannot yet explain

In a cross-sectional study of 808 Brazilian adults planning to attend ayahuasca ceremonies, greater prior experience with the brew was associated with lower depression, anxiety, and stress scores, as well as higher spiritual well-being and stronger metaphysical beliefs. Because the study was observational and relied on self-reported data, it cannot show that ayahuasca caused these differences.

Cockroaches have a reputation for surviving almost anything, but this diet proved deadly

A laboratory study tested how ultra-processed, unprocessed, and mixed diets affected survival in 127 lobster cockroaches, Nauphoeta cinerea. Cockroaches fed only ultra-processed foods had higher mortality than those given unprocessed or mixed diets, although the study could not determine whether processing, ingredients, nutrition, or differences in food intake caused the effect.

Stricter glucose control may affect quality of life in people living with diabetes

New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows that, in people living with diabetes (type 1 or 2) using data from continuous glucose monitoring (CGM) devices paired with daily quality-of-life ratings, days with more widely fluctuating glucose readings (while still within safe limits) are followed by days with a better quality life compared to days with more stricter control– suggesting the burden of that stricter control could be preventing those individuals with stricter control from enjoying various activities.

Giant-nucleus cells form the foundation of early-stage cancer

Iron is an essential micronutrient, but excess iron can damage cells and increase cancer risk. While many cells die from iron-induced oxidative stress, a subset survives and may become cancerous.

Neighborhood environments impact long-term health of 9/11 responders

Twenty-five years after the September 11 terrorist attacks, researchers at the Icahn School of Medicine at Mount Sinai have found that environmental conditions where World Trade Center responders live may influence their long-term physical and mental health.

Cancer treatments alter the landscape of genetic mutations in healthy body tissues

Cancer treatments, including chemotherapy and radiotherapy, give a growth advantage to cells with particular genetic changes in healthy tissue, new research finds.

Early studies hint that ketones may affect pathways linked to PTSD

An integrative review found that ketogenic therapy may influence metabolic, inflammatory, oxidative stress, and neurotransmitter pathways implicated in PTSD, with animal studies and small human studies reporting early signs of symptom improvement. Human evidence remains limited to very small cohorts, case reports, and pilot studies, and controlled trials have yet to establish clinical efficacy.

People with ADHD face higher odds of gastrointestinal problems

University of Warwick researchers have analyzed data from over 1.9 million people across 23 studies and found that ADHD is linked to an almost 50% increase in overall gastrointestinal symptoms compared with people without ADHD The association was even stronger for specific problems: nearly double the odds of constipation, a 58% increase in irritable bowel syndrome, and more than four times the odds of encopresis (loss of bowel control).

Strength training shows no added arrhythmia risk in people with arrhythmogenic cardiomyopathy

People living with arrhythmogenic cardiomyopathy (ACM), a heritable heart condition that can significantly increase risks for sudden cardiac death, are advised to avoid high-intensity aerobic exercise.

Five minutes of coffee aroma was linked to shifts in mood and brain activity

Short-term coffee aroma exposure was followed by reductions in several negative mood measures and an increase in an EEG-derived relaxation index in 20 healthy young adults. Heart rate and HRV did not change significantly, and the uncontrolled study cannot establish that coffee aroma caused the observed responses.

Shortages of crucial cancer medications continue to impact US healthcare

Today, the National Comprehensive Cancer Network® (NCCN®)-an alliance of leading cancer centers-published updated data on the current impact of generic cancer medication shortages in the United States.

Study reveals how brain reward circuitry builds psychological resilience

New research has uncovered that how the brain responds to anticipated rewards plays a key role in building psychological resilience after a traumatic experience.

New study reveals extreme heat seasons are expanding symmetrically

Extreme heat has become more common-both research and lived experience document this-but when it arrives is a different question.

Rituximab alters T-cell metabolism in patients with nephrotic syndrome

Nephrotic syndrome is caused when the filtering system in the kidneys is damaged, allowing large amounts of protein to leak into the urine.

Nighttime light exposure may alter heart structure and function

Exposure to light during the nighttime is linked to important and potentially harmful changes to the structure and function of the heart, according to a study of more than 11,000 people published in the European Heart Journal today (Thursday).

Rentosertib shifts multiple proteomic aging clocks toward younger age profiles in IPF trial

Researchers applied six proteomic aging clocks to serum samples from a phase 2a trial of rentosertib in people with idiopathic pulmonary fibrosis and found treatment-associated shifts toward younger predicted biological-age profiles, particularly with the 30 mg twice-daily regimen. Additional proteomic analyses linked treatment to changes in senescence, metabolism, growth-factor signaling, and fibrosis-related pathways, although the study could not determine whether these effects reflected genuine geroprotection rather than disease modification.

Blood protein profiling could improve rare disease diagnosis

Researchers from Queen Mary University of London, the Berlin Institute of Health at Charité (BIH) and Genomics England have shown that measuring proteins in the blood can provide important additional clues about the effects of genetic variants, helping to identify diagnoses and potential new disease-causing genes that genome sequencing alone has been unable to resolve.

The link between PM2.5 and ADHD held up after researchers tested other explanations

Using two decades of U.S. county-level data, researchers found that long-term PM2.5 exposure was robustly associated with higher childhood ADHD prevalence, while associations with low birth weight and diabetes weakened after accounting for county-specific temporal trends. The ADHD association persisted after socioeconomic, demographic, state-level, exposure-period, and spatial adjustments, although the ecological study cannot establish an individual-level causal relationship.

Study links methylglyoxal stress to immunotherapy resistance in triple-negative cancer

The metabolism of cancer cells may play a key role in their ability to evade the immune system. This is demonstrated by a new study conducted by researchers at the University of Liège, which reveals how methylglyoxal stress – a by-product of tumor metabolism – promotes immunosuppression and the formation of metastases, and may contribute to resistance to immunotherapy and the progression of triple-negative cancer.

Early pregnancy emotions may predict childhood developmental delay risks

Pregnancy is often one of the biggest emotional and physical transitions in a woman's life. Alongside the well-known physical changes, many women also experience shifts in mood and mental health during pregnancy and after giving birth, with anxiety and depression being quite common.
