Your immune system harbors a lifetime’s worth of information about threats it’s encountered—a biological Rolodex of baddies. Often the perpetrators are viruses and bacteria you’ve conquered; others are undercover agents like vaccines given to trigger protective immune responses or even red herrings in the form of healthy tissue caught in immunological crossfire.

Researchers at the University of Jyväskylä, in collaboration with the University of Turku’s Institute of Biomedicine, University of Helsinki and Nova Hospital of Central Finland, have developed an advanced artificial intelligence tool for automatic analysis of colorectal cancer tissue slides.

The lab of Filippo Veglia, Ph.D., at The Wistar Institute has discovered a previously unknown mechanism for how aggressive brain cancers reprogram immune system cells from fighting cancer to enabling further tumor growth. The team’s findings were published in the paper “Functional reprogramming of neutrophils within the brain tumor microenvironment by hypoxia-driven histone lactylation,” from Cancer Discovery.

MINNEAPOLIS and MISGAV, Israel, Feb. 27, 2025 /PRNewswire/ — Arcuro Medical Ltd., (“Arcuro”) today announced that it received FDA 510(k) clearance for its new SuperBall-RC™ system for use in rotator cuff repair procedures.

University of Queensland researchers have developed a new rapid sensor that can detect pregnancy complications, such as gestational diabetes, preterm birth risks and hypertension, as early as 11 weeks—with a simple blood test.

A study led by researchers at Mass General Brigham suggests a nasal spray developed to target neuroinflammation could one day be an effective treatment for traumatic brain injury (TBI). By studying the effects of the nasal anti-CD3 in a mouse model of TBI, researchers found the spray could reduce damage to the central nervous system and behavioral deficits, suggesting a potential therapeutic approach for TBI and other acute forms of brain injury.

Using an animal model of multiple sclerosis (MS), researchers at the National Institutes of Health (NIH) have created a four-dimensional brain map that reveals how lesions similar to those seen in human MS form. These findings, published in Science, provide a window into the early disease state and could help identify potential targets for MS treatments and brain tissue repair.

Red blood cells carry oxygen from the lungs to every other organ, and blood-forming stem cells must make about 200 billion new red blood cells each day to keep the oxygen flowing.
