Antibiotic resistance predicts higher mortality risk in 17-year follow-up—linked to diet and gender

A population-based study led by the University of Turku, Finland, investigated factors associated with the prevalence of antibiotic resistance. In addition to antibiotic use, diet, gender, living environment, income level and certain gut bacteria were associated with a higher burden of resistance. A higher resistance burden was associated with a 40% higher risk of all-cause mortality during the follow-up.

Antibiotic-resistant bacteria cause more than one million deaths per year worldwide, and the number is rising fast.

A recent study shows that an increase in relative mortality risk can be predicted by high resistance burden as well as by elevated blood pressure or type 2 diabetes. The number of antibiotic resistance genes found in gut bacteria predicted the risk of sepsis or death during a long follow-up period of almost two decades.

New AI tool deciphers mysteries of nanoparticle motion in liquid environments

Nanoparticles—the tiniest building blocks of our world—are constantly in motion, bouncing, shifting, and drifting in unpredictable paths shaped by invisible forces and random environmental fluctuations.

Better understanding their movements is key to developing better medicines, materials, and sensors. But observing and interpreting their motion at the atomic scale has presented scientists with major challenges.

Researchers in Georgia Tech’s School of Chemical and Biomolecular Engineering (ChBE) have developed an (AI) model that learns the underlying physics governing those movements.

What’s Missing in the Psychopathic Brain? Scientists Find Startling Clues

A research team has used the Julich-Brain Atlas to identify specific brain structures linked to antisocial behavior. A recent publication in the European Archives of Psychiatry and Clinical Neuroscience provides new insights into structural brain differences linked to psychopathy, a condition str

Researchers grow 400+ brain cell types—a leap for Alzheimer’s and Parkinson’s research

Scientists at ETH Zurich have broken new ground by generating over 400 types of nerve cells from stem cells in the lab, far surpassing previous efforts that produced only a few dozen. By systematically experimenting with combinations of morphogens and gene regulators, the researchers replicated the vast diversity of neurons found in the human brain. This breakthrough holds major promise for studying neurological diseases like Alzheimer’s and Parkinson’s, creating more accurate models for drug testing, and eventually even enabling neuron replacement therapies.

Mysterious New Structure Discovered Hiding Inside Human Cells

After centuries of mapping the human body in ever-finer detail, scientists are still making discoveries. Here we are, in 2025, and a previously unknown cellular structure that could be vital to our health has just been added to the anatomy books.

The membrane-bound organelle appears to play a huge role in helping cells sort, discard, and recycle their contents. It’s called a hemifusome, and a team of scientists says it could shed new light on disease.

“This is like discovering a new recycling center inside the cell,” said biophysicist Seham Ebrahim of the University of Virginia. “We think the hemifusome helps manage how cells package and process material, and when this goes wrong, it may contribute to diseases that affect many systems in the body.”
