Rethinking mRNA vaccines: Liver targeting can suppress immunity, while muscle boosts it
A new study by researchers at the Icahn School of Medicine at Mount Sinai overturns a longstanding assumption about how mRNA vaccines generate immunity, revealing that certain non-immune cells help determine vaccine effectiveness.

Not all organs age alike: AI unveils the molecular impact of menopause across the female body
Despite affecting half of the world's population, menopause has historically been understudied and misunderstood, both in biomedical research and clinical practice. However, with the increase in life expectancy, the number ...

Microplastics turn up in nearly every human brain sample, including healthy tissue
Tiny micro- and nanoplastic fragments seem to be turning up everywhere, including one of the most well-protected parts of the human body—the brain. In a recent study conducted by Chinese researchers, they found microplastics ...
Cancer cells can rewrite RNA messages, creating new drug targets in aggressive tumors
Scientists have uncovered an unexpected way cells can generate cancer-driving proteins—by cutting RNA into shorter, functional fragments rather than following the standard blueprint. This process, newly termed as "RNA dicing," ...

How the immune system battles lifelong viral infections acquired at birth
Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers from the University of Basel show ...

Excessive cholesterol in astrocytes linked to cognitive decline in Alzheimer's mice
Alzheimer's disease (AD) is a neurodegenerative disorder that leads to progressive memory loss and a decline in mental functions. Several past studies have linked this disease to the accumulation of the protein amyloid-β ...
AI model detects normally 'invisible' tissue changes of pancreatic cancer at stage 0
An AI model (REDMOD) can pick up the very early subtle tissue changes of pancreatic ductal adenocarcinoma, the most common form of pancreatic cancer, which conventional imaging and the human eye find difficult to detect, ...

A banned chemical still lingers, and its strangest effect may depend on sex, genes and one common vitamin
In two new studies, researchers at the UC Davis MIND Institute have clarified how a long-banned group of chemicals, called polychlorinated biphenyls (PCBs), affect genetic activity. The research helps explain how biological ...

Smart soft sensors restore surgeons' sense of touch in minimally invasive procedures
Researchers at NYU Abu Dhabi have developed soft, flexible sensors that help restore a surgeon's sense of touch during minimally invasive (keyhole) surgery. These procedures allow for faster recovery and less pain, but surgeons ...

How bones make marrow: Newly identified 'organizer' cells also reappear after fractures
Bone marrow is the spongy tissue located within the hollow center of bones, serving as the primary site for the continuous production of red blood cells, platelets, and white blood cells. Despite its physiological importance, ...

Digital twin can reveal alcohol consumption in crime cases
Using a so-called digital twin, it is possible to predict with greater precision than at present how much alcohol a person has consumed and at what time. The study was conducted by researchers at Linköping University and ...

From gut to brain: Scientists engineer bacteria to treat severe liver-related brain dysfunction
When the liver fails, toxins—such as ammonia—that should be filtered from the blood build up and reach the brain. The result is hepatic encephalopathy (HE), a devastating neurological complication of liver disease that can ...

Cellular pathways may underlie some differences in physical fitness
Patterns of molecular activity in the blood may hold clues not only to how fit someone is, but also to the biological processes that support physical performance. Researchers at MIT, GE HealthCare, and the U.S. Military Academy ...

Fluorescent quail embryos could help solve serious birth defects in humans
The quail is a small, unassuming bird that glides rather than flies and prefers to hide under bushes than to perch on top of a tree. And now, it's also helping scientists understand serious birth defects in humans.

Experimental drug may restore movement after stroke
Every stroke begins with a sudden interruption of blood flow in the brain. But what happens afterward—why neurons continue to lose function and die over the following days—has remained one of the most important unanswered ...
