Variations of Severely Reduced Myocardial Flow Reserve in PET Myocardial Perfusion Imaging

Severely reduced myocardial flow reserve in cardiac positron emission tomography is a diagnostic challenge. đŸ«€â˜ąïž This JACCIMG iPIX lays out the full differential—from 3-vessel coronary artery disease to artifacts—to spot the patterns, avoid the pitfalls, and not miss the diagnosis.

The Journal of the American College of Cardiology (JACC) stands as a leading global resource for impactful cardiovascular research, delivering essential peer-reviewed articles and crucial clinical practice guidelines.

Brain immune cells may drive more damage in females than males with Alzheimer’s

More than 7 million Americans have Alzheimer’s disease, and two-thirds of them are women, according to the Alzheimer’s Association. The O’Banion Lab at the Del Monte Institute for Neuroscience at the University of Rochester has long been studying this disease and is looking more closely at the differences between male and female brains.

“It is well documented that males and females are diagnosed with Alzheimer’s disease at different rates,” said M. Kerry O’Banion, MD, Ph.D., professor of Neuroscience and Neurology. “But we still do not have a great understanding of why this is the case. We can only improve any possible treatment or prevention of this disease if we know the why, when, and where these differences are occurring.”

Bird feeders have caused a dramatic evolution of California hummingbirds

Evolution doesn’t always take thousands or millions of years. Sometimes it happens right before our eyes.

Such is the case with the Anna’s hummingbird, a species that has undergone a dramatic transformation in just a few generations, all thanks to the advent of hummingbird feeders.

Beaks have grown longer and larger, and ranges have expanded to follow the feeders.

Antibiotic resistance forecast to kill 39 million people by 2050

According to the most comprehensive study to date, the global death toll from antibiotic resistance is expected to reach 1.9 million people annually by 2050.

AI model forecasts speech development in deaf children after cochlear implants

An AI model using deep transfer learning—the most advanced form of machine learning—has predicted spoken language outcomes with 92% accuracy from one to three years after patients received cochlear implants (implanted electronic hearing device).

The research is published in the journal JAMA Otolaryngology–Head & Neck Surgery.

Although cochlear implantation is the only effective treatment to improve hearing and enable spoken language for children with severe to profound hearing loss, spoken language development after early implantation is more variable in comparison to children born with typical hearing. If children who are likely to have more difficulty with spoken language are identified prior to implantation, intensified therapy can be offered earlier to improve their speech.

Modified tau thwarts aggregation in neurodegenerative disease—while retaining its biological function

A designer version of the tau protein, developed by a team led by UT Southwestern Medical Center researchers, maintains its biological function while resisting aggregation, a pathological trait linked to neurodegenerative diseases called tauopathies.

These findings, reported in Structure, could lead to new treatments for conditions including Alzheimer’s disease, frontotemporal dementia, chronic traumatic encephalopathy (CTE), and progressive supranuclear palsy.

“This is the first step toward creating a molecule that could, in principle, replace a protein that’s pathogenic (disease-causing) while still retaining its normal function,” said study leader Lukasz Joachimiak, Ph.D., Associate Professor in the Center for Alzheimer’s and Neurodegenerative Diseases and of Biochemistry and Biophysics at UT Southwestern.

New Brain Signal Predicts Alzheimer’s Years Before Diagnosis

Scientists at the Carney Institute for Brain Science have discovered specific patterns of electrical signals in the brain that may help forecast whether a person will go on to develop Alzheimer’s disease. Using a specialized tool designed to examine the electrical signals produced by neurons, sci

Prescriptions Rising for a New Non-Opioid Analgesic, but Clinicians Are Still Learning Where It Fits

Prescriptions for the new non-opioid pain medication suzetrigine more than doubled between April and August 2025, according to analysis from Epic Research. The increase indicates a growing interest in opioid alternatives for acute pain, even as clinicians grapple with how and where the drug best fits in practice.

Despite a surge in prescriptions for the non-opioid pain drug suzetrigine, clinicians are still sorting out who benefits the most and when.
