American College of Lifestyle Medicine welcomes national resolution advancing nature as a foundation for health and well-being

The American College of Lifestyle Medicine welcomes a national resolution advancing nature as a foundation for health and well-being, recognizing nature's role in supporting human health and promoting collaboration among healthcare, research, and conservation communities. The resolution also supports the establishment of a strategic pa...

NIH awards Mount Sinai researcher $3.3 million to study how “forever chemicals” may contribute to IBD

A new five-year study, supported by a $3.3 million NIH grant, will investigate the link between PFAS exposure and IBD, with researchers exploring biological changes that occur years before diagnosis. The study aims to uncover mechanisms that could help identify individuals at risk and inform prevention strategies.

Mass General Brigham women’s heart health leader to receive the 2026 Dr. Nanette K. Wenger Research Goes Red® Award

Dr. Emily Lau's research found that maternal cardiovascular disease and pregnancy-related cardiovascular complications increased over nearly two decades, with higher rates among non-Hispanic Black women. The study emphasizes the need to make cardiovascular health a routine part of care before, during, and after pregnancy to address dis...

Alliance Foundation trials and Natera announce AFT-70 navigate: A global, randomized, phase iii trial evaluating genentech’s oral Selective Estrogen Receptor Degrader (SERD) with SignateraTM MRD-Guided CDK4/6 inhibitor therapy in ER+/HER2− breast canc

The AFT-70 NAVIGATE trial tests a novel molecular residual disease-guided treatment strategy for ER-positive/HER2-negative breast cancer patients. The trial pairs giredestrant with longitudinal Signatera Genome MRD monitoring to identify patients who may benefit from treatment escalation with a CDK4/6 inhibitor.

Food processing influences metabolism and brain activity

Researchers found that minimally and highly processed meals with matched nutritional profiles produced distinct metabolic responses and activity in the brain's reward system. The study suggests that food processing may affect how the body and brain respond to food, potentially leading to overconsumption and long-term health effects.

How cells fight back after bacterial toxins break through

Researchers at Juntendo University discovered a lipid signaling pathway involving 12-HHT and BLT2 that promotes plasma membrane repair and protects cells from membrane-damaging insults. Cells with enhanced BLT2 signaling showed better survival rates, less membrane leakage, and improved mitochondrial health after toxin exposure.

Does the gender pay gap extend to AI? New University of Limerick research finds female AI agents ‘paid’ less

A study by University of Limerick researchers found that female AI agents were paid less than their male-presenting counterparts, despite using the same technology. Participants in the virtual reality office setting gave more monetary rewards to the male-presenting AI agent, demonstrating a gender bias in interactions with AI.

New global survey shines a light on the patients who rely on plasma-derived medicines—and the donors who make them possible

A global survey of over 1,100 patients, caregivers, and healthcare providers found that 69% noticed a change in their health or someone they care for within a few months of plasma-derived medicine treatment, with 77% expressing gratitude to donors. The survey also revealed high confidence in plasma-derived medicines' safety and efficacy.

B-cell repertoire analysis visualizes humoral immune maturation after hematopoietic stem cell transplantation

Researchers developed a novel method to visualize humoral immune maturation after hematopoietic stem cell transplantation, tracking B-cell repertoire changes over time. The pGen-SHM plot revealed distinct populations with varying generation probabilities and somatic hypermutation rates, indicating the recovery of humoral immunity.

Black people at higher risk of severe complications during pregnancy, labor, and postpartum

A new study published in the Canadian Medical Association Journal found that Black people in Canada are at a higher risk of severe maternal morbidity, including life-threatening conditions, compared to White people. The study analyzed data from 1.5 million births and found a 66% increased risk of severe complications among Black people...

When the clocks stop changing: What time is best for health?

A new analysis in the Canadian Medical Association Journal suggests that permanent standard time is the preferred choice for health, as it preserves morning light and aligns with human circadian biology. This can lead to improved sleep, mood, and overall health, particularly for vulnerable populations such as children, adolescents, and...
