3D-printed anatomical models bring better surgical outcomes

JMIR Publications released a story on how 3D-printed anatomical models are being used to improve surgical outcomes in its News and Perspectives section. Authored by ICU nurse and health writer Jenna Congdon, BSN, RN, "Printing Personalized Medicine: 3D Models Bring Better Surgical Outcomes" reports how ENT surgeon Kyle VanKoevering, MD first used 3D modeling to recreate, then print, the head of a fetus with a potentially airway-obstructing facial mass in order to determine whether a risky surgical procedure would be necessary during delivery.

Estrogen decline alters brain cell matrix in older females

A largely overlooked space between cells in women's brains may hold the key to understanding memory loss tied to estrogen decline after menopause, reports a new preclinical Northwestern Medicine study.

Study explains how environmental acidity destabilizes internal cellular traffic

A new scientific study led by the Universidad Carlos III de Madrid (UC3M) describes the mechano-chemical mechanism by which the acidity of the cellular environment destabilizes microtubules, the "avenues" that organize internal cellular traffic.

Study links ceramide levels to prostate cancer drug response differences

Ceramides-lipid molecules in cells that affect many physiological functions including cell differentiation, migration, and death-and their metabolites have been implicated in the development of cancer and other conditions.

How heat-smart cities can protect outdoor recreation in a warming world

This review shows how rising humid heat threatens the health benefits of nature-based recreation in tropical cities. The authors call for heat-smart urban planning, targeted advisories, and inclusive strategies that keep outdoor activity safe, accessible, and beneficial.

Neural progenitor timing influences formation of distinct brain layers

The outer regions of the brain, the cortex, have specific layers of different cells - neurons - that are similarly ordered among all mammals, from tiny mouse brains to huge elephant brains.

Why Kenya, Ethiopia, Japan, and the US stand out in global distance running

This global analysis of 152,943 endurance runners found that nationality, gender, age, and race distance were significantly associated with running performance from 1999 to 2024. Men were faster across all distances, women were generally older in longer races, and runners from Kenya, Ethiopia, Japan, and the United States showed distinct participation and performance patterns.

How a tiny H5N1 dose triggers massive virus shedding in cow milk

Experimental infection studies in lactating Holstein cows showed that H5N1 B3.13 can infect the bovine mammary gland at doses as low as 10 TCID50, producing extremely high viral loads in milk. However, the virus did not transmit to sentinel cows through repeated exposure to contaminated milking equipment or through close contact under high-biocontainment conditions, suggesting that real-world dairy-farm spread depends on additional cofactors.

Targeted nerve stimulation boosts movement-related brain activity in humans

The vagus nerve connects the brain to major organs throughout the body and plays important roles in many bodily functions.

Novel RNA modification mechanism drives metabolic fatty liver disease progression

Nonalcoholic fatty liver disease (NAFLD) is a prevalent metabolic disorder with a complex pathogenesis. Although epitranscriptomic modifications such as N6-methyladenosine (m6A) have been implicated in NAFLD, the role of N1-methyladenosine (m1A) and its regulators is largely unexplored.

New peptide triggers domino effect to suppress bladder cancer

Recently, a research team led by Professors Dahong Zhang and Qi Zhang from the Urology Department and the Institute of Urology at Zhejiang Provincial People's Hospital and the Translational Medicine Center discovered that a bladder tumor-targeting polyarginine peptide, R11, can directly bind to actin, destabilize the G-actin tetramer, and trigger the cascade breakdown of the actin-plectin-vimentin/ITGβ4 axis (referred to as the "cytoskeletal domino effect").

Outdoor running combats winter vitamin D deficiency better than supplements

An EHU study says that vitamin D supplements can help to strengthen the immune system, but not to improve athletic performance.

Ferroptosis exploits unique cancer metabolic vulnerabilities to bypass traditional apoptotic evasion pathways

A new wave of scientific understanding is placing ferroptosis, a distinct form of iron-dependent cell death, at the forefront of efforts to overcome drug resistance in digestive cancers. These cancers, which include gastric, colorectal, liver, pancreatic, and esophageal malignancies, remain among the most challenging to treat due to their ability to evade standard therapies.

Small non-coding RNA molecule precisely controls vital gene expression and cellular balance

A rapidly advancing area of biomedical innovation is shining a spotlight on miR-128-3p, a small yet powerful molecule with the potential to reshape how diseases—especially cancer—are detected, monitored, and treated. This microRNA, part of a broader class of non-coding RNAs, plays a critical role in regulating gene activity and maintaining cellular homeostasis.
