New study challenges long-held view of common bacterial resident of the lungs

Our bodies are teeming with more than 35 trillion bacteria, coexisting in microbiomes inside our guts, mouths, lungs, skin and urogenital tract.

Bacterial extracellular vesicles show potential for cancer diagnosis and treatment

Bacteria shed membrane-enclosed tiny particles filled with proteins, lipids, DNA, RNA and metabolites. These particles, commonly known as bacterial extracellular vesicles (BEVs), are now being explored as possible tools for cancer diagnosis and treatment.

Your social life may leave a mark on how fast you age

Positive social experiences were associated with longer survival, while childhood adversity predicted shorter survival in a 1,309-person longitudinal cohort followed for nearly 15 years. Epigenetic aging, particularly GrimAge2, emerged as the strongest potential pathway linking social experiences with mortality risk.

Anesthesia boosts success of turning breech babies before labor

Women carrying breech babies have a better chance of avoiding a cesarean delivery (C-section) when spinal or epidural anesthesia is used during external cephalic version (ECV), a procedure used to turn the baby head-down before labor, according to the American Society of Anesthesiologists (ASA).

Aging clock analysis identifies key genes in opioid dependence

A new research paper was published in Volume 18 of Aging on July 27, 2026, titled "Transcriptomic aging clock analysis identifies key genes in opioid dependence."

Dysregulated immune cells drive hidden inflammation after heart attacks

People with narrowing of the coronary arteries have low-grade, uncontrolled inflammation in the body, even if they are symptom-free and receiving optimal treatment.

Molecular mapping reveals hidden cellular programs in heart transplant rejection

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

How well you balance and move may say more about longevity than you think

Objective fitness testing in 13,423 older adults in Taiwan found that higher physical fitness was consistently associated with lower all-cause mortality over a median seven years. Balance and agility, lower-body strength, and cardiorespiratory fitness showed the strongest associations, while a composite fitness score produced the steepest mortality gradient.

ANESTHESIOLOGY 2026 to highlight latest advances in anesthesia care

Ketamine given during C-sections could help ease early symptoms of postpartum depression. Common pain relievers, such as ibuprofen, may reduce the risk of delirium after surgery.

Dexamethasone calms lung inflammation without weakening core immune responses

Researchers from Trinity College Dublin and St. James's Hospital have shown that dexamethasone, a commonly prescribed anti-inflammatory steroid, can reduce harmful inflammation triggered by Mycobacterium avium without weakening the ability of human immune cells to control the infection.

Waist size predicts heart disease risk better than body mass index

The size of a person's midsection is a better indicator of cardiovascular disease risk when compared to their body mass index (BMI) alone, according to a study published in JACC, the flagship journal of the American College of Cardiology.

SwRI researchers design better inhalers for young children

A Southwest Research Institute (SwRI) project is developing techniques to improve inhalers for young children and other people who can't inhale deeply.

$Bone loss alone fails to explain diabetes-related fracture risk$

Bone loss alone fails to explain diabetes-related fracture risk

A new study published in Diabetes Care finds that bone loss alone does not explain the increased fracture risk observed in some older adults with type 2 diabetes.

New computational tool identifies hidden genes driving asthma

Researchers at Columbia University Mailman School of Public Health, in collaboration with investigators at the University of Chicago, have developed a new computational framework that helps scientists identify genes that play central roles in diseases such as asthma but are often overlooked by existing genetic analysis methods.

Scientists identify parasite-specific protein linked to chronic Toxoplasma infections

Toxoplasma gondii, or Toxoplasma, is a parasite that infects hundreds of millions of people around the world.

Natural hormone activates brain-to-liver signaling pathway to suppress liver inflammation

Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown signalling pathway, opening new possibilities for treating advanced fatty liver disease.

Scientific statement reframes cardiovascular care for older patients with cognitive impairment and frailty

Older adults with cardiovascular disease (CVD) often have coexisting cognitive impairment and frailty, conditions that can significantly affect treatment decisions, recovery, independence and quality of life and should be considered as part of an aging-informed approach to care, according to a new American College of Cardiology Scientific Statement published in JACC, the flagship journal of the ACC.

New pathway explains how zombie cells trigger chronic inflammation

Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases.

Spatial transcriptomics study elucidates cellular dynamics during heart transplant rejection

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

Single-dose psilocybin shows promise for treatment-resistant depression in NHS trial

A single 25-mg dose of psilocybin with psychological support was feasible to deliver within an NHS setting and produced large preliminary reductions in depressive symptoms among adults with treatment-resistant depression. The Phase 2 feasibility trial also found the treatment was generally well tolerated, although functional unblinding and expectancy effects mean larger, longer efficacy studies are needed.
